# PART	I

# ITEM	1. Business.

# General

We	are	a	global	security	and	aerospace	company	principally	engaged	in	the	research,	design,	development,	manufacture,	integration	and	sustainment	of	advanced technology	systems,	products	and	services.	We	also	provide	a	broad	range	of	management,	engineering,	technical,	scientific,	logistics	and	information	services.	We serve	both	U.S.	and	international	customers	with	products	and	services	that	have	defense,	civil	and	commercial	applications,	with	our	principal	customers	being	agencies of	the	U.S.	Government.	In	2015,	78%	of	our	$46.1	billion	in	net	sales	were	from	the	U.S.	Government,	either	as	a	prime	contractor	or	as	a	subcontractor	(including	58% from	the	Department	of	Defense	(DoD)),	21%	were	from	international	customers	(including	foreign	military	sales	(FMS)	contracted	through	the	U.S.	Government)	and 1%	were	from	U.S.	commercial	and	other	customers.	Our	main	areas	of	focus	are	in	defense,	space,	intelligence,	homeland	security	and	information	technology, including	cybersecurity.

We	operate	in	an	environment	characterized	by	both	increasing	complexity	in	global	security	and	continuing	economic	pressures	in	the	U.S.	and	globally.	A significant	component	of	our	strategy	in	this	environment	is	to	focus	on	program	execution,	improving	the	quality	and	predictability	of	the	delivery	of	our	products	and services,	and	placing	security	capability	quickly	into	the	hands	of	our	U.S.	and	international	customers	at	affordable	prices.	Recognizing	that	our	customers	are	resource constrained,	we	are	endeavoring	to	develop	and	extend	our	portfolio	domestically	in	a	disciplined	manner	with	a	focus	on	adjacent	markets	close	to	our	core	capabilities, as	well	as	growing	our	international	sales.	We	continue	to	focus	on	affordability	initiatives.	We	also	expect	to	continue	to	invest	in	technologies	to	fulfill	new	mission requirements	for	our	customers	and	invest	in	our	people	so	that	we	have	the	technical	skills	necessary	to	succeed	without	limiting	our	ability	to	return	cash	to	our investors	in	the	form	of	dividends	and	share	repurchases.

We	operate	in	five	business	segments:	Aeronautics,	Information	Systems	&	Global	Solutions	(IS&GS),	Missiles	and	Fire	Control	(MFC),	Mission	Systems	and Training	(MST)	and	Space	Systems.	We	organize	our	business	segments	based	on	the	nature	of	the	products	and	services	offered.

# Strategic	Actions

# Acquisition	of	Sikorsky	Aircraft	Corporation

On	November	6,	2015,	pursuant	to	a	Stock	Purchase	Agreement,	dated	as	of	July	19,	2015	by	and	between	us	and	United	Technologies	Corporation	(UTC)	and certain	wholly-owned	subsidiaries	of	UTC,	we	completed	the	acquisition	of	Sikorsky	Aircraft	Corporation	(Sikorsky)	for	$9.0	billion,	net	of	cash	acquired.	Sikorsky,	a global	company	primarily	engaged	in	the	design,	manufacture	and	support	of	military	and	commercial	helicopters,	has	become	a	wholly-owned	subsidiary	of	ours, aligned	under	the	MST	business	segment.	We	funded	the	acquisition	with	new	debt	issuances,	commercial	paper	and	cash	on	hand.	We	and	UTC	made	a	joint	election under	Section	338(h)(10)	of	the	Internal	Revenue	Code,	which	treats	the	transaction	as	an	asset	purchase	for	tax	purposes.	This	election	generates	a	cash	tax	benefit	with an	estimated	net	present	value	of	$1.9	billion	for	us	and	our	stockholders.	The	financial	results	of	the	acquired	Sikorsky	business	have	been	included	in	our	consolidated results	of	operations	from	the	November	6,	2015	acquisition	date	through	December	31,	2015.	Accordingly,	the	consolidated	financial	results	for	the	year	ended December	31,	2015	do	not	reflect	a	full	year	of	Sikorsky	operations.

# Strategic	Review	of	Government	Information	Technology	(IT)	and	Technical	Services	Businesses

# Information	Systems	&	Global	Solutions	Divestiture

On	January	26,	2016	we	entered	into	definitive	agreements	to	separate	and	combine	our	IS&GS	business	segment	with	Leidos	Holdings,	Inc.	(Leidos)	in	a	tax- efficient	Reverse	Morris	Trust	transaction	anticipated	to	unlock	approximately	$5.0	billion	in	estimated	enterprise	value	for	our	stockholders,	including	a	$1.8	billion one-time	special	cash	payment	to	us.	We	intend	to	use	the	net	proceeds	of	the	transaction	to	repay	debt,	pay	dividends	or	repurchase	our	stock.	Additionally,	our stockholders	will	receive	approximately	50.5	percent	of	the	outstanding	equity	of	Leidos	on	a	fully	diluted	basis	(approximately	77	million	shares)	with	an	estimated value	of	$3.2	billion	based	on	Leidos'	stock	price	on	the	date	of	announcement.	However,	the	actual	value	of	the	stock	to	be	received	by	our	stockholders	will	depend	on the	value	of	such	shares	at	the	time	of	closing	of	the	transaction	and	our	stockholders	may	receive	more	or	less	than	the	anticipated	value.	At	our	election,	the distribution	may	be	effected	by	means	of	a	pro	rata	dividend	in	a	spin-off	transaction	or	in	an	exchange	offer

for	outstanding	Lockheed	Martin	shares	in	a	split-off	transaction.	The	transaction	structure,	which	is	subject	to	market	conditions,	is	currently	contemplated	to	be	a	split- off	transaction	resulting	in	a	decrease	in	our	outstanding	common	shares	and	a	significant	book	gain	at	closing.	In	a	split-off	transaction,	only	those	stockholders	that elect	to	participate	will	receive	Leidos	shares	in	the	merger	transaction,	provided,	that,	if	the	exchange	offer	is	not	fully	subscribed,	Lockheed	Martin	will	spin-off	the remaining	shares	to	be	converted	into	Leidos	stock	in	the	merger	pro	rata.

Subsequent	to	the	program	realignment	described	below,	our	IS&GS	business	segment	represents	the	government	IT	and	technical	services	businesses	that	were under	strategic	review.	The	transaction	is	expected	to	close	in	the	third	or	fourth	quarter	of	2016.	Until	closing,	IS&GS	will	operate	as	a	business	segment	and	financial results	for	the	IS&GS	business	segment	will	be	reported	in	our	continuing	operations.

# Program	Realignment

During	the	fourth	quarter	of	2015,	we	realigned	certain	programs	among	our	business	segments	in	connection	with	the	strategic	review	of	our	government	IT	and technical	services	businesses.	As	part	of	the	realignment:

•command,	control,	communications,	computers,	intelligence,	surveillance	and	reconnaissance	(C4ISR)	and	government	cyber	programs	were	transferred	from	the IS&GS	business	segment	to	the	MST	business	segment;

•energy	solutions	programs	were	transferred	from	the	IS&GS	business	segment	to	the	MFC	business	segment;

•space	ground	station	programs	were	transferred	from	the	IS&GS	business	segment	to	Space	Systems	business	segment;	and

•technical	services	programs	were	transferred	from	the	MFC	business	segment	to	the	IS&GS	business	segment.

In	connection	with	the	realignment,	goodwill	was	reallocated	between	affected	reporting	units	on	a	relative	fair	value	basis.	We	performed	goodwill	impairment tests	prior	and	subsequent	to	the	realignment,	and	there	was	no	indication	of	goodwill	impairment.

Subsequent	to	the	program	realignment,	the	government	IT	and	technical	services	businesses	that	were	under	strategic	review	are	now	aligned	under	the	IS&GS business	segment.

# Business	Segments

The	amounts,	discussion	and	presentation	of	our	business	segments	as	set	forth	in	this	Annual	Report	on	Form	10-K	reflect	the	program	realignment	described above	for	all	periods	presented.	The	realignment	did	not	impact	our	consolidated	results	of	operations.	See	"Note	5	–	Information	on	Business	Segments"	for	additional information	including	revised	historical	segment	results	under	our	new	structure.

# Aeronautics

In	2015,	our	Aeronautics	business	segment	generated	net	sales	of	$15.6	billion,	which	represented	34%	of	our	total	consolidated	net	sales.	Aeronautics'	customers include	the	military	services	and	various	other	government	agencies	of	the	U.S.	and	other	countries.	In	2015,	U.S.	Government	customers	accounted	for	72%	and international	customers	accounted	for	28%	of	Aeronautics'	net	sales.	Net	sales	from	Aeronautics'	combat	aircraft	products	and	services	represented	25%,	23%,	and	21% of	our	total	consolidated	net	sales	in	2015,	2014,	and	2013.

Aeronautics	is	engaged	in	the	research,	design,	development,	manufacture,	integration,	sustainment,	support	and	upgrade	of	advanced	military	aircraft,	including combat	and	air	mobility	aircraft,	unmanned	air	vehicles	and	related	technologies.	Aeronautics'	major	programs	include:

•F-35	Lightning	II	Joint	Strike	Fighter	–	international	multi-role,	multi-variant,	fifth	generation	stealth	fighter

•	 C-130	Hercules	–	international	tactical	airlifter

•F-16	Fighting	Falcon	–	low-cost,	combat-proven,	international	multi-role	fighter

•	 C-5M	Super	Galaxy	–	strategic	airlifter

•F-22	Raptor	–	air	dominance	and	multi-mission	fifth	generation	stealth	fighter.

The	F-35	program	is	our	largest	program,	generating	20%	of	our	total	consolidated	net	sales,	as	well	as	59%	of	Aeronautics'	net	sales	in	2015.	The	F-35	program consists	of	development	contracts,	multiple	production	contracts,	and

sustainment	activities.	The	development	contracts	are	being	performed	concurrent	with	the	production	contracts.	Concurrent	performance	of	development	and	production contracts	is	used	for	complex	programs	to	test	aircraft,	shorten	the	time	to	field	systems	and	achieve	overall	cost	savings.	We	expect	the	System	Development	and Demonstration	portion	of	the	development	contracts	will	be	substantially	complete	in	2017,	with	less	significant	efforts	continuing	into	2019.	Production	of	the	aircraft is	 expected	 to	 continue	 for	 many	 years	 given	 the	 U.S.	 Government's	 current	 inventory	 objective	 of	 2,443	 aircraft	 for	 the	Air	 Force,	 Marine	 Corps	 and	 Navy; commitments	from	our	eight	international	partners	and	three	international	customers;	as	well	as	expressions	of	interest	from	other	countries.	During	2015,	we	delivered 45	aircraft	to	our	U.S.	and	international	partners,	resulting	in	total	deliveries	of	154	production	aircraft	as	of	December	31,	2015.	We	have	114	production	aircraft	in backlog	as	of	December	31,	2015,	including	orders	from	our	international	partners.	For	additional	information	on	the	F-35	program,	see	"Status	of	the	F-35	Program"	in Management's	Discussion	and	Analysis	of	Financial	Condition	and	Results	of	Operations.

Aeronautics	produces	and	provides	support	and	sustainment	services	for	the	C-130J	Super	Hercules,	as	well	as	upgrades	and	support	services	for	the	legacy	C-130 Hercules	worldwide	fleet.	We	delivered	21	C-130J	aircraft	in	2015,	including	one	to	international	customers.	We	have	97	aircraft	in	our	backlog	as	of	December	31, 2015	with	advanced	funding	from	customers	for	additional	C-130J	aircraft	not	currently	in	backlog.	Our	C-130J	backlog	extends	into	2020.

Aeronautics	 currently	 produces	 F-16	 aircraft	 for	 international	 customers.	Aeronautics	 also	 provides	 service-life	 extension,	 modernization	 and	 other	 upgrade programs	for	our	customers'	F-16	aircraft.	We	delivered	11	F-16	aircraft	in	2015.	As	of	December	31,	2015,	we	have	20	F-16	aircraft	in	backlog	with	backlog	extending into	2017.

Aeronautics	provides	sustainment	services	for	the	existing	U.S.	Air	Force	C-5	Galaxy	fleet	and	modernization	activities	to	convert	49	C-5	Galaxy	aircraft	to	the	C- 5M	Super	Galaxy	configuration.	These	modernization	activities	include	the	installation	of	new	engines,	landing	gear	and	systems	and	other	improvements	that	enable	a shorter	takeoff,	a	higher	climb	rate,	an	increased	cargo	load	and	longer	flight	range.	As	of	December	31,	2015,	we	had	delivered	29	C-5M	aircraft	under	these modernization	activities,	including	nine	C-5M	aircraft	delivered	in	2015.	As	of	December	31,	2015,	we	have	20	C-5	aircraft	in	backlog	with	backlog	extending	into 2018.

While	production	and	deliveries	of	F-22	aircraft	were	completed	in	2012,	Aeronautics	continues	to	provide	modernization	and	sustainment	activities	for	the	U.S. Air	 Force's	 F-22	 aircraft	 fleet.	 The	 modernization	 program	 comprises	 upgrading	 existing	 systems	 requirements,	 developing	 new	 systems	 requirements,	 adding capabilities	and	enhancing	the	performance	of	the	weapon	systems.	The	sustainment	program	consists	of	sustaining	the	weapon	systems	of	the	F-22	fleet,	providing training	systems,	customer	support,	integrated	support	planning,	supply	chain	management,	aircraft	modifications	and	heavy	maintenance,	systems	engineering	and support	products.

In	addition	 to	 the	above	aircraft	programs,	Aeronautics	 is	 involved	 in	advanced	development	programs	 incorporating	 innovative	design	and	rapid	prototype applications.	Our	Advanced	Development	Programs	(ADP)	organization,	also	known	as	Skunk	Works®,	is	focused	on	future	systems,	including	unmanned	aerial systems	and	next	generation	capabilities	for	advanced	strike,	intelligence,	surveillance,	reconnaissance,	situational	awareness	and	air	mobility.	We	continue	to	explore technology	advancement	and	insertion	in	our	existing	aircraft.	We	also	are	involved	in	numerous	network-enabled	activities	that	allow	separate	systems	to	work	together to	increase	effectiveness	and	we	continue	to	invest	in	new	technologies	to	maintain	and	enhance	competitiveness	in	military	aircraft	design,	development	and	production.

# Information	Systems	&	Global	Solutions

In	2015,	our	IS&GS	business	segment	generated	net	sales	of	$5.6	billion,	which	represented	12%	of	our	total	consolidated	net	sales.	IS&GS'	customers	include various	government	agencies	of	the	U.S.	and	other	countries,	military	services,	as	well	as	commercial	and	other	customers.	In	2015,	U.S.	Government	customers accounted	for	89%,	international	customers	accounted	for	9%	and	U.S.	commercial	and	other	customers	accounted	for	2%	of	IS&GS'	net	sales.	IS&GS	has	been impacted	by	the	continued	downturn	in	certain	federal	agencies'	information	technology	budgets	and	increased	re-competition	on	existing	contracts	coupled	with	the fragmentation	of	large	contracts	into	multiple	smaller	contracts	that	are	awarded	primarily	on	the	basis	of	price.

IS&GS	provides	advanced	technology	systems	and	expertise,	integrated	information	technology	solutions	and	management	services	across	a	broad	spectrum	of applications	for	civil,	defense,	intelligence	and	other	government	customers.	In	addition,	IS&GS	supports	the	needs	of	customers	in	data	analytics,	data	center	operation and	air	traffic	management.	IS&GS	provides	network-enabled	situational	awareness	and	integrates	complex	global	systems	to	help	our	customers	gather,	analyze	and securely	distribute	critical	data.	While	IS&GS	has	a	portfolio	of	many	smaller	contracts,	as	compared	to	our	other	business	segments,	this	business	segment's	major programs	include:

•	 The	Hanford	Mission	Support	contract,	a	program	to	provide	infrastructure	and	site	support	services	to	the	Department	of	Energy.

•	 The	En	Route	Automation	Modernization	(ERAM)	contract,	a	program	to	replace	the	Federal	Aviation	Administration's	infrastructure	with	a	modern	automation environment	that	includes	new	functions	and	capabilities.

•	 QTC	business	that	provides	IT-enabled	case	management	of	outsourced	medical	evaluations	for	federal,	state	and	commercial	customers.

•	 The	National	Science	Foundation	Antarctic	Support	program,	which	manages	sites	and	equipment	to	enable	universities,	research	institutions	and	federal	agencies	to conduct	scientific	research	in	the	Antarctic.

IS&GS'	 Technical	 Services	 business,	 which	 has	 been	 realigned	 to	 IS&GS	 from	 our	 MFC	 business	 segment	 as	 part	 of	 our	 strategic	 review,	 provides	 a comprehensive	portfolio	of	technical	and	sustainment	services	to	enhance	our	customers'	mission	success,	with	core	capabilities	in	engineering	services;	global	aviation solutions;	command,	control,	communications,	computers,	intelligence,	surveillance	and	reconnaissance	(C4ISR)	product	support;	counter	threat	services;	and	education and	sustainment	services.

# Missiles	and	Fire	Control

In	2015,	our	MFC	business	segment	generated	net	sales	of	$6.7	billion,	which	represented	14%	of	our	total	consolidated	net	sales.	MFC's	customers	include	the military	services,	principally	the	U.S.	Army,	and	various	government	agencies	of	the	U.S.	and	other	countries,	as	well	as	commercial	and	other	customers.	In	2015,	U.S. Government	customers	accounted	for	61%,	international	customers	accounted	for	36%	and	U.S.	commercial	and	other	customers	accounted	for	3%	of	MFC's	net	sales.

MFC	 provides	 air	 and	 missile	 defense	 systems;	 tactical	 missiles	 and	 air-to-ground	 precision	 strike	 weapon	 systems;	 logistics;	 fire	 control	 systems;	 mission operations	support,	readiness,	engineering	support	and	integration	services;	manned	and	unmanned	ground	vehicles;	and	energy	management	solutions.	MFC's	major programs	include:

•	 The	Patriot	Advanced	Capability-3	(PAC-3)	and	Terminal	High	Altitude	Area	Defense	(THAAD)	air	and	missile	defense	programs.	PAC-3	is	an	advanced	defensive missile	for	the	U.S.	Army	and	international	customers	designed	to	intercept	and	eliminate	incoming	airborne	threats	using	kinetic	energy.	THAAD	is	a	transportable defensive	missile	system	for	the	U.S.	Government	and	international	customers	designed	to	engage	targets	both	within	and	outside	of	the	Earth's	atmosphere. •	 The	Multiple	Launch	Rocket	System	(MLRS),	Hellfire,	Joint	Air-to-Surface	Standoff	Missile	(JASSM)	and	Javelin	tactical	missile	programs.	MLRS	is	a	highly mobile,	automatic	system	that	fires	surface-to-surface	rockets	and	missiles	from	the	M270	and	High	Mobility	Artillery	Rocket	System	platforms	produced	for	the U.S.	Army	and	international	customers.

On	November	6,	2015,	we	acquired	Sikorsky	and	aligned	the	Sikorsky	business	under	our	MST	business	segment.	The	results	of	the	acquired	Sikorsky	business have	been	included	in	our	financial	results	from	the	period	subsequent	to	the	completion	of	the	acquisition	on	November	6,	2015.	Accordingly,	our	consolidated operating	results	and	MST	business	segment	operating	results	for	the	year	ended	December	31,	2015	do	not	reflect	a	full	year	of	Sikorsky	operations.

Sikorsky	is	one	of	the	world's	largest	helicopter	companies	and	manufactures	military	and	commercial	helicopters.	Sikorsky	designs,	manufactures,	services	and supports	military	and	commercial	helicopters.	Current	major	production	programs	include	the	UH-60M	Black	Hawk	medium-transport	helicopter	and	HH-60M	medical evacuation	helicopter	for	the	U.S.	and	foreign	governments,	the	S-70	Black	Hawk	for	foreign	governments,	the	MH-60S	Seahawk	helicopter	for	the	U.S.	Navy	and	the MH-60R	 Seahawk	 helicopter	 for	 the	 U.S.	 and	 foreign	 navies,	 the	 S-70B	 Seahawk	 helicopter	 for	 foreign	 naval	 missions,	 and	 the	 S-76	 and	 S-92	 helicopters	 for commercial	operations.

# Space	Systems

In	2015,	our	Space	Systems	business	segment	generated	net	sales	of	$9.1	billion,	which	represented	20%	of	our	total	consolidated	net	sales.	Space	Systems' customers	include	various	U.S.	government	agencies	and	commercial	customers.	In	2015,	U.S.	Government	customers	accounted	for	97%,	international	customers accounted	for	2%	and	U.S.	commercial	and	other	customers	accounted	for	1%	of	Space	Systems'	net	sales.	Net	sales	from	Space	Systems'	satellite	products	and services	represented	11%	of	our	total	consolidated	net	sales	in	2015	and	12%	in	both	2014	and	2013.

Space	Systems	is	engaged	in	the	research	and	development,	design,	engineering	and	production	of	satellites,	strategic	and	defensive	missile	systems	and	space transportation	systems.	Space	Systems	provides	network-enabled	situational	awareness	and	integrates	complex	global	systems	to	help	our	customers	gather,	analyze	and securely	distribute	critical	intelligence	data.	Space	Systems	is	also	responsible	for	various	classified	systems	and	services	in	support	of	vital	national	security	systems. Space	Systems'	major	programs	include:

•	 The	Trident	II	D5	Fleet	Ballistic	Missile,	a	program	with	the	U.S.	Navy	for	the	only	submarine-launched	intercontinental	ballistic	missile	currently	in	production	in the	U.S.

# Financial	and	Other	Business	Segment	Information

For	additional	information	regarding	our	business	segments,	including	comparative	segment	net	sales,	operating	profit	and	related	financial	information	for	2015, 2014,	and	2013,	see	"Business	Segment	Results	of	Operations"	in	Management's	Discussion	and	Analysis	of	Financial	Condition	and	Results	of	Operations	and	"Note	5 –	Information	on	Business	Segments"	of	our	consolidated	financial	statements.

# Competition

Our	broad	portfolio	of	products	and	services	competes	both	domestically	and	internationally	against	products	and	services	of	other	large	aerospace,	defense	and information	 technology	 companies,	 as	 well	 as	 numerous	 smaller	 competitors,	 particularly	 in	 certain	 of	 our	 services	 businesses.	 We	 often	 form	 teams	 with	 our competitors	in	efforts	to	provide	our	customers	with	the	best	mix	of	capabilities	to	address	specific	requirements.	In	some	areas	of	our	business,	customer	requirements are	changing	to	encourage	expanded	competition,	such	as	information	technology	contracts	where	there	may	be	a	wide	range	of	small	to	large	contractors	bidding	on procurements.	Additionally,	information	technology	procurements	are	increasingly	focusing	on	price	over	other	factors	of	competition.	Principal	factors	of	competition include	the	value	of	our	products	and	services	to	the	customer;	technical	and	management	capability;	the	ability	to	develop	and	implement	complex,	integrated	system architectures;	total	cost	of	ownership;	our	demonstrated	ability	to	execute	and	perform	against	contract	requirements;	and	our	ability	to	provide	timely	solutions.

The	competition	for	international	sales	is	generally	subject	to	U.S.	Government	stipulations	(e.g.,	export	restrictions,	market	access,	technology	transfer,	industrial cooperation	 and	 contracting	 practices).	 We	 may	 compete	 against	 U.S.	 and	 non-U.S.	 companies	 (or	 teams)	 for	 contract	 awards	 by	 international	 governments. International	competitions	also	may	be	subject	to	different	laws	or	contracting	practices	of	international	governments	that	may	affect	how	we	structure	our	bid	for	the procurement.	In	many	international	procurements,	the	purchasing	government's	relationship	with	the	U.S.	and	its	industrial	cooperation	programs	are	also	important factors	 in	determining	 the	outcome	of	a	competition.	It	 is	common	for	 international	customers	 to	require	contractors	 to	comply	with	 their	 industrial	cooperation regulations,	sometimes	referred	to	as	offset	requirements,	and	we	have	entered	into	foreign	offset	agreements	as	part	of	securing	some	international	business.	For	more information	 concerning	 offset	 agreements,	 see	 "Contractual	 Commitments	 and	 Off-Balance	 Sheet	Arrangements"	 in	 Management's	 Discussion	 and	Analysis	 of Financial	Condition	and	Results	of	Operations.

# Patents

We	routinely	apply	for	and	own	a	substantial	number	of	U.S.	and	international	patents	related	to	the	products	and	services	we	provide.	In	addition	to	owning	a	large portfolio	of	intellectual	property,	we	also	license	intellectual	property	to	and	from	third	parties.	The	U.S.	Government	has	licenses	in	our	patents	that	are	developed	in performance	of	government	contracts	and	it	may	use	or	authorize	others	to	use	the	inventions	covered	by	these	patents	for	government	purposes.	Unpatented	research, development	and	engineering	skills	also	make	an	important	contribution	to	our	business.	Although	our	intellectual	property	rights	in	the	aggregate	are	important	to	the operation	of	our	business,	we	do	not	believe	that	any	existing	patent,	license	or	other	intellectual	property	right	is	of	such	importance	that	its	loss	or	termination	would have	a	material	adverse	effect	on	our	business	taken	as	a	whole.

# Raw	Materials	and	Seasonality

Certain	of	our	products	require	relatively	scarce	raw	materials.	Historically,	we	have	been	successful	in	obtaining	the	raw	materials	and	other	supplies	needed	in our	manufacturing	processes.	We	seek	to	manage	raw	materials	supply	risk	through	long-term	contracts	and	by	maintaining	an	acceptable	level	of	the	key	materials	in inventories.

Aluminum	and	titanium	are	important	raw	materials	used	in	certain	of	our	Aeronautics	and	Space	Systems	programs.	Long-term	agreements	have	helped	enable	a continued	supply	of	aluminum	and	titanium.	Carbon	fiber	is	an	important	ingredient	in	composite	materials	used	in	our	Aeronautics	programs,	such	as	the	F-35	aircraft. Aluminum	lithium,	which	we	use	for	F-16	aircraft	structural	components,	is	currently	only	available	from	limited	sources.	We	have	been	advised	by	some	suppliers	that pricing	and	the	timing	of	availability	of	materials	in	some	commodities	markets	can	fluctuate	widely.	These	fluctuations	may	negatively	affect	the	price	and	availability of	certain	materials.	While	we	do	not	anticipate	material	problems	regarding	the	supply	of	our	raw	materials	and	believe	that	we	have	taken	appropriate	measures	to mitigate	these	variations,	if	key	materials	become	unavailable	or	if	pricing	fluctuates	widely	in	the	future,	it	could	result	in	delay	of	one	or	more	of	our	programs, increased	costs	or	reduced	operating	profits.

No	material	portion	of	our	business	is	considered	to	be	seasonal.	Various	factors	can	affect	the	distribution	of	our	sales	between	accounting	periods,	including	the timing	of	government	awards,	the	availability	of	government	funding,	product	deliveries	and	customer	acceptance.

# Government	Contracts	and	Regulations

Our	business	is	heavily	regulated.	We	contract	with	numerous	U.S.	Government	agencies	and	entities,	including	all	branches	of	the	U.S.	military,	the	departments of	 Defense,	 Homeland	 Security,	 Justice,	 Commerce,	 Health	 and	 Human	 Services,	 Transportation	 and	 Energy,	 the	 U.S.	 Postal	 Service,	 the	 Social	 Security Administration,	the	Federal	Aviation	Administration,	NASA,	the	U.S.	Environmental	Protection	Agency	and	Veterans	Affairs.	Similar	government	authorities	exist	in other	countries	and	regulate	our	international	efforts.

We	must	comply	with,	and	are	affected	by,	laws	and	regulations	relating	to	the	formation,	administration	and	performance	of	U.S.	Government	and	other	contracts. These	laws	and	regulations,	among	other	things:

•require	certification	and	disclosure	of	all	cost	or	pricing	data	in	connection	with	certain	types	of	contract	negotiations;

•impose	specific	and	unique	cost	accounting	practices	that	may	differ	from	U.S.	generally	accepted	accounting	principles;

•impose	 acquisition	 regulations,	 which	 may	 change	 or	 be	 replaced	 over	 time,	 that	 define	 allowable	 and	 unallowable	 costs	 and	 otherwise	 govern	 our right to reimbursement	under	certain	cost-based	U.S.	Government	contracts;

•require	specific	security	controls	to	protect	DoD	controlled	unclassified	technical	information	and	restrict	the	use	and	dissemination	of	information	classified	for national	security	purposes	and	the	export	of	certain	products,	services	and	technical	data;	and

•require	the	review	and	approval	of	contractor	business	systems,	defined	in	the	regulations	as:	(i)	Accounting	System;	(ii)	Estimating	System;	(iii)	Earned	Value Management	System,	for	managing	cost	and	schedule	performance	on	certain	complex	programs;	(iv)	Purchasing	System;	(v)	Material	Management	and	Accounting System,	for	planning,	controlling	and	accounting	for	the	acquisition,	use,	issuing	and	disposition	of	material;	and	(vi)	Property	Management	System.

The	U.S.	Government	may	terminate	any	of	our	government	contracts	and	subcontracts	either	at	its	convenience	or	for	default	based	on	our	performance.	If	a contract	is	terminated	for	convenience,	we	generally	are	protected	by	provisions	covering	reimbursement	for	costs	incurred	on	the	contract	and	profit	on	those	costs.	If	a contract	is	terminated	for	default,	we	generally	are	entitled	to	payments	for	our	work	that	has	been	accepted	by	the	U.S.	Government;	however,	the	U.S.	Government could	make	claims	to	reduce	the	contract	value	or	recover	its	procurement	costs	and	could	assess	other	special	penalties.	For	more	information	regarding	the	U.S. Government's	 right	 to	 terminate	 our	 contracts,	 see	 Item	 1A	 –	 Risk	 Factors.	 For	 more	 information	 regarding	 government	 contracting	 laws	 and	 regulations,	 see Item	1A	–	Risk	Factors	as	well	as	"Critical	Accounting	Policies	–	Contract	Accounting	/	Sales	Recognition"	in	Management's	Discussion	and	Analysis	of	Financial Condition	and	Results	of	Operations.

A	portion	of	our	business	is	classified	by	the	U.S.	Government	and	cannot	be	specifically	described.	The	operating	results	of	these	classified	contracts	are	included in	our	consolidated	financial	statements.	The	business	risks	associated	with	classified	contracts	historically	have	not	differed	materially	from	those	of	our	other	U.S. Government	contracts.	Our	internal	controls	addressing	the	financial	reporting	of	classified	contracts	are	consistent	with	our	internal	controls	for	our	non-classified contracts.

Our	operations	are	subject	to	and	affected	by	various	federal,	state,	local	and	foreign	environmental	protection	laws	and	regulations	regarding	the	discharge	of materials	into	the	environment	or	otherwise	regulating	the	protection	of	the	environment.	While	the	extent	of	our	financial	exposure	cannot	in	all	cases	be	reasonably estimated,	the	costs	of	environmental	compliance	have	not	had,	and	we	do	not	expect	that	these	costs	will	have,	a	material	adverse	effect	on	our	earnings,	financial position	and	cash	flow,	primarily	because	most	of	our	environmental	costs	are	allowable	in	establishing

the	price	of	our	products	and	services	under	our	contracts	with	the	U.S.	Government.	For	information	regarding	these	matters,	including	current	estimates	of	the	amounts that	we	believe	are	required	for	remediation	or	cleanup	to	the	extent	that	they	are	probable	and	estimable,	see	"Critical	Accounting	Policies	–	Environmental	Matters"	in Management's	Discussion	and	Analysis	of	Financial	Condition	and	Results	of	Operations	and	"Note	14	–	Legal	Proceedings,	Commitments	and	Contingencies"	of	our consolidated	financial	statements.	See	also	the	discussion	of	environmental	matters	within	Section	1A	–	Risk	Factors.

# Backlog

At	December	31,	2015,	our	backlog	was	$99.6	billion	compared	with	$80.5	billion	at	December	31,	2014.	Backlog	at	December	31,	2015	includes	$15.6	billion related	to	Sikorsky	and	$4.8	billion	related	to	our	IS&GS	business	segment,	which	we	plan	to	divest	in	2016.	Sikorsky	backlog	may	change	as	we	complete	our	acquired backlog	analysis.	Backlog	is	converted	into	sales	in	future	periods	as	work	is	performed	or	deliveries	are	made.	Approximately	$43.0	billion,	or	43%,	of	our	backlog	at December	31,	2015	is	expected	to	be	converted	into	sales	in	2016.

Our	backlog	includes	both	funded	(firm	orders	for	our	products	and	services	for	which	funding	has	been	both	authorized	and	appropriated	by	the	customer –	Congress,	in	the	case	of	U.S.	Government	agencies)	and	unfunded	(firm	orders	for	which	funding	has	not	been	appropriated)	amounts.	We	do	not	include	unexercised options	or	potential	orders	under	indefinite-delivery,	indefinite-quantity	agreements	in	our	backlog.	If	any	of	our	contracts	with	firm	orders	were	to	be	terminated,	our backlog	would	be	reduced	by	the	expected	value	of	the	unfilled	orders	of	such	contracts.	Our	backlog	would	also	be	reduced	in	connection	with	the	planned	divestiture	of our	IS&GS	business	segment.	Funded	backlog	was	$70.7	billion	at	December	31,	2015,	as	compared	to	$56.5	billion	at	December	31,	2014.	For	backlog	related	to	each of	our	business	segments,	see	"Business	Segment	Results	of	Operations"	in	Management's	Discussion	and	Analysis	of	Financial	Condition	and	Results	of	Operations.

# Research	and	Development

We	conduct	research	and	development	(R&D)	activities	under	customer-sponsored	contracts	and	with	our	own	independent	R&D	funds.	Our	independent	R&D costs	include	basic	research,	applied	research,	development,	systems	and	other	concept	formulation	studies.	Generally,	these	costs	are	allocated	among	all	contracts	and programs	in	progress	under	U.S.	Government	contractual	arrangements.	Costs	we	incur	under	customer-sponsored	R&D	programs	pursuant	to	contracts	are	included	in net	sales	and	cost	of	sales.	Under	certain	arrangements	in	which	a	customer	shares	in	product	development	costs,	our	portion	of	the	unreimbursed	costs	is	expensed	as incurred	in	cost	of	sales.	Independent	R&D	costs	charged	to	cost	of	sales	were	$839	million	in	2015,	$751	million	in	2014,	and	$697	million	in	2013.	See	"Research	and development	and	similar	costs"	in	"Note	1	–	Significant	Accounting	Policies"	of	our	consolidated	financial	statements.

# Employees

At	December	31,	2015,	we	had	approximately	126,000	employees,	about	93%	of	whom	were	located	in	the	U.S.	Approximately	18%	of	our	employees	are	covered by	collective	bargaining	agreements	with	various	unions.	A	number	of	our	existing	collective	bargaining	agreements	expire	in	any	given	year.	Historically,	we	have been	successful	in	negotiating	renewals	to	expiring	agreements	without	any	material	disruption	of	operating	activities.	Management	considers	employee	relations	to	be good.

Except	where	required	by	applicable	law,	we	expressly	disclaim	a	duty	to	provide	updates	to	forward-looking	statements	after	the	date	of	this	Form	10-K	to	reflect subsequent	events,	changed	circumstances,	changes	in	expectations,	or	the	estimates	and	assumptions	associated	with	them.	The	forward-looking	statements	in	this	Form 10-K	are	intended	to	be	subject	to	the	safe	harbor	protection	provided	by	the	federal	securities	laws.

# ITEM	1A. Risk	Factors.

An	investment	in	our	common	stock	or	debt	securities	involves	risks	and	uncertainties.	We	seek	to	identify,	manage	and	mitigate	risks	to	our	business,	but	risk	and uncertainty	cannot	be	eliminated	or	necessarily	predicted.	The	outcome	of	one	or	more	of	these	risks	could	have	a	material	effect	on	our	operating	results,	financial position,	or	cash	flows.	You	should	carefully	consider	the	following	factors,	in	addition	to	the	other	information	contained	in	this	Annual	Report	on	Form	10-K,	before deciding	to	purchase	our	common	stock	or	debt	securities.

# We	depend	heavily	on	contracts	with	the	U.S.	Government	for	a	substantial	portion	of	our	business.

We	derived	78%	of	our	total	net	sales	from	the	U.S.	Government	in	2015,	including	58%	from	the	Department	of	Defense	(DoD).	We	expect	to	continue	to	derive most	 of	 our	 sales	 from	 work	 performed	 under	 U.S.	 Government	 contracts.	 Those	 contracts	 are	 conditioned	 upon	 the	 continuing	 availability	 of	 Congressional appropriations.	Congress	usually	appropriates	funds	on	a	fiscal-year	basis	even	though	contract	performance	may	extend	over	many	years.	Consequently,	contracts	are often	partially	funded	initially	and	additional	funds	are	committed	only	as	Congress	makes	further	appropriations.	If	we	incur	costs	in	excess	of	funds	obligated	on	a contract,	we	may	be	at	risk	for	reimbursement	of	those	costs	unless	and	until	additional	funds	are	obligated	to	the	contract.

As	 discussed	 within	 the	 "Industry	 Considerations"	 in	 Management's	 Discussion	 and	Analysis	 of	 Financial	 Condition	 and	 Results	 of	 Operations,	 the	 U.S. Government	continues	to	face	significant	deficit	reduction	pressures	and	it	is	likely	that	discretionary	spending	by	the	U.S.	Government	will	remain	constrained	for	a number	of	years.	Under	such	conditions,	large	or	complex	programs,	which	consist	of	multiple	contracts	and	phases,	are	potentially	subject	to	increased	scrutiny.	Our largest	program,	the	F-35,	represented	20%	of	our	total	net	sales	in	2015	and	is	expected	to	represent	a	higher	percentage	of	our	sales	in	future	years.	A	decision	to	cut spending	or	reduce	planned	orders	could	have	an	adverse	impact	on	our	results	of	operations.	For	more	information	regarding	the	F-35	program,	see	"Status	of	the	F-35 Program"	in	Management's	Discussion	and	Analysis	of	Financial	Condition	and	Results	of	Operations.

Based	upon	our	diverse	range	of	defense,	homeland	security	and	information	technology	products	and	services,	we	believe	that	this	makes	it	less	likely	that	cuts	in any	specific	contract	or	program	will	have	a	long-term	effect	on	our	business.	However,	termination	of	multiple	or	large	programs	or	contracts	could	adversely	affect our	business	and	future	financial	performance.	Potential	changes	in	funding	priorities	may	afford	new	or	additional	opportunities	for	our	businesses	in	terms

of	existing,	follow-on	or	replacement	programs.	While	we	would	expect	to	compete	and	be	well	positioned	as	the	incumbent	on	existing	programs,	we	may	not	be successful	or	the	replacement	programs	may	be	funded	at	lower	levels.

Generally,	we	expect	that	the	impact	of	budget	reductions	on	our	operating	results	will	lag	in	certain	of	our	businesses	with	longer	cycles	such	as	our	Aeronautics and	Space	Systems	business	segments	and	in	our	products	businesses	within	our	Missiles	and	Fire	Control	(MFC)	and	Mission	Systems	and	Training	(MST)	business segments	due	 to	our	production	contract	backlog.	However,	our	businesses	with	smaller,	short-term	contracts	are	 the	most	susceptible	 to	 the	 impacts	of	budget reductions,	such	as	our	Information	Systems	&	Global	Solutions	(IS&GS)	business	segment.	We	have	also	experienced	increased	market	pressures	in	these	services businesses	including	lower	in-theater	support	as	troop	levels	are	drawn	down	and	increased	re-competition	on	existing	contracts	coupled	with	the	fragmentation	of	large contracts	into	multiple	smaller	contracts	that	are	awarded	primarily	on	the	basis	of	price.	Additionally,	our	services	businesses	across	most	of	our	business	segments have	experienced	lower	volume	due	to	improved	product	field	performance	that	require	less	service	support.	Changes	in	our	business	environment	require	us	to	be	agile and	evolve	our	business	models,	processes	and	products.

# We	are	subject	to	a	number	of	procurement	laws	and	regulations.	Our	business	and	our	reputation	could	be	adversely	affected	if	we	fail	to	comply	with	these laws.

We	must	comply	with	and	are	affected	by	laws	and	regulations	relating	to	the	award,	administration	and	performance	of	U.S.	Government	contracts.	Government contract	laws	and	regulations	affect	how	we	do	business	with	our	customers	and	impose	certain	risks	and	costs	on	our	business.	A	violation	of	specific	laws	and regulations,	by	us,	a	supplier	or	a	venture	partner,	could	harm	our	reputation	and	result	in	the	imposition	of	fines	and	penalties,	the	termination	of	our	contracts, suspension	or	debarment	from	bidding	on	or	being	awarded	contracts,	loss	of	our	ability	to	export	products	or	services	and	civil	or	criminal	investigations	or	proceedings.

In	some	instances,	these	laws	and	regulations	impose	terms	or	rights	that	are	different	from	those	typically	found	in	commercial	transactions.	For	example,	the	U.S. Government	may	terminate	any	of	our	government	contracts	and	subcontracts	either	at	its	convenience	or	for	default	based	on	our	performance.	Upon	termination	for convenience	of	a	fixed-price	type	contract,	we	normally	are	entitled	to	receive	the	purchase	price	for	delivered	items,	reimbursement	for	allowable	costs	for	work-in- process	and	an	allowance	for	profit	on	the	contract	or	adjustment	for	loss	if	completion	of	performance	would	have	resulted	in	a	loss.

Upon	termination	for	convenience	of	a	cost-reimbursable	contract,	we	normally	are	entitled	to	reimbursement	of	allowable	costs	plus	a	portion	of	the	fee.	Allowable costs	would	include	our	cost	to	terminate	agreements	with	our	suppliers	and	subcontractors.	The	amount	of	the	fee	recovered,	if	any,	is	related	to	the	portion	of	the	work accomplished	prior	to	termination	and	is	determined	by	negotiation.	We	attempt	to	ensure	that	adequate	funds	are	available	by	notifying	the	customer	when	its	estimated costs,	 including	 those	associated	with	a	possible	 termination	for	convenience,	approach	 levels	specified	as	being	allotted	 to	 its	programs.	As	funds	are	 typically appropriated	on	a	fiscal-year	basis	and	as	the	costs	of	a	termination	for	convenience	may	exceed	the	costs	of	continuing	a	program	in	a	given	fiscal	year,	occasionally programs	do	not	have	sufficient	funds	appropriated	to	cover	the	termination	costs	were	the	government	to	terminate	them	for	convenience.	Under	such	circumstances,	the U.S.	Government	could	assert	that	it	is	not	required	to	appropriate	additional	funding.

A	termination	arising	out	of	our	default	may	expose	us	to	liability	and	have	a	material	adverse	effect	on	our	ability	to	compete	for	future	contracts	and	orders.	In addition,	on	those	contracts	for	which	we	are	teamed	with	others	and	are	not	the	prime	contractor,	the	U.S.	Government	could	terminate	a	prime	contract	under	which	we are	a	subcontractor,	notwithstanding	the	quality	of	our	services	as	a	subcontractor.	In	the	case	of	termination	for	default,	the	U.S.	Government	could	make	claims	to reduce	the	contract	value	or	recover	its	procurement	costs	and	could	assess	other	special	penalties.	However,	under	such	circumstances	we	have	rights	and	remedial actions	under	laws	and	the	Federal	Acquisition	Regulation	(FAR).

In	addition,	certain	of	our	U.S.	Government	contracts	span	one	or	more	base	years	and	multiple	option	years.	The	U.S.	Government	generally	has	the	right	not	to exercise	option	periods	and	may	not	exercise	an	option	period	for	various	reasons.	However,	the	U.S.	Government	may	exercise	option	periods,	even	for	contracts	for which	it	is	expected	that	our	costs	may	exceed	the	contract	price	or	ceiling.

U.S.	Government	agencies,	including	the	Defense	Contract	Audit	Agency,	the	Defense	Contract	Management	Agency	and	various	agency	Inspectors	General, routinely	audit	and	investigate	government	contractors.	These	agencies	review	a	contractor's	performance	under	its	contracts,	its	cost	structure,	its	business	systems	and compliance	with	applicable	laws,	regulations	and	standards.	Any	costs	found	to	be	misclassified	may	be	subject	to	repayment.	We	have	unaudited	and/or

unsettled	incurred	cost	claims	related	to	past	years,	which	places	risk	on	our	ability	to	issue	final	billings	on	contracts	for	which	authorized	and	appropriated	funds	may be	expiring.

Certain	deficiencies	identified	during	government	audits	of	contractor	business	systems	may	result	in	the	government	withholding	payments	on	our	billings.	Such deficiencies	have	not	impacted	our	internal	control	over	financial	reporting.	Withholding	payments	on	billings	are	capped	at	5%	of	billings	when	deficiencies	impact	a single	business	system	and	10%	when	deficiencies	impact	multiple	systems.	Such	withholdings	are	typically	reduced	to	2%	after	the	contractor's	corrective	action	plan has	 been	 accepted	 and	 progress	 to	 implement	 the	 corrective	 actions	 has	 been	 demonstrated,	 and	 withholdings	 are	 withdrawn	 upon	 satisfactory	 completion	 and verification	of	the	corrective	action	plan.

If	an	audit	or	 investigation	uncovers	 improper	or	 illegal	activities,	we	may	be	subject	 to	civil	or	criminal	penalties	and	administrative	sanctions,	 including reductions	of	the	value	of	contracts,	contract	modifications	or	terminations,	forfeiture	of	profits,	suspension	of	payments,	penalties,	fines	and	suspension,	or	prohibition from	doing	business	with	the	U.S.	Government.	In	addition,	we	could	suffer	serious	reputational	harm	if	allegations	of	impropriety	were	made	against	us.	Similar government	oversight	exists	in	most	other	countries	where	we	conduct	business.

# Our	profitability	and	cash	flow	may	vary	based	on	the	mix	of	our	contracts	and	programs,	our	performance,	our	ability	to	control	costs	and	evolving	U.S. Government	procurement	policies.

Our	profitability	and	cash	flow	may	vary	materially	depending	on	the	types	of	government	contracts	undertaken,	the	nature	of	products	produced	or	services performed	under	those	contracts,	the	costs	incurred	in	performing	the	work,	the	achievement	of	other	performance	objectives	and	the	stage	of	performance	at	which	the right	to	receive	fees	is	determined,	particularly	under	award	and	incentive-fee	contracts.

Our	backlog	includes	a	variety	of	contract	types	that	are	intended	to	address	changing	risk	and	reward	profiles	as	a	program	matures.	Contract	types	include	cost- reimbursable,	fixed-price	incentive-fee,	fixed-price	and	time-and-materials	contracts.	Contracts	for	development	programs	with	complex	design	and	technical	challenges are	typically	cost-reimbursable.	Under	cost-reimbursable	contracts,	we	are	reimbursed	for	allowable	costs	and	paid	a	fee,	which	may	be	fixed	or	performance-based.	In these	cases,	the	associated	financial	risks	primarily	relate	to	a	reduction	in	fees	and	the	program	could	be	cancelled	if	cost,	schedule	or	technical	performance	issues arise.

Other	contracts	in	backlog	are	for	the	transition	from	development	to	production	(e.g.,	low-rate	initial	production	(LRIP)	contracts),	which	includes	the	challenge	of starting	and	stabilizing	a	manufacturing	production	and	test	line	while	the	final	design	is	being	validated.	These	generally	are	cost-reimbursable	or	fixed-price	incentive- fee	contracts.	Under	a	fixed-price	incentive-fee	contract,	the	allowable	costs	incurred	are	eligible	for	reimbursement	but	are	subject	to	a	cost-share	arrangement,	which affects	 profitability.	 Generally,	 if	 our	 costs	 exceed	 the	 contract	 target	 cost	 or	 are	 not	 allowable	 under	 the	 applicable	 regulations,	 we	 may	 not	 be	 able	 to	 obtain reimbursement	for	all	costs	and	may	have	our	fees	reduced	or	eliminated.

There	are	also	contracts	for	production,	as	well	as	operations	and	maintenance	of	the	delivered	products,	that	have	the	challenge	of	achieving	a	stable	production and	delivery	rate,	while	maintaining	operability	of	the	product	after	delivery.	These	contracts	are	mainly	fixed-price,	although	some	operations	and	maintenance contracts	are	time-and-materials	type.	Under	fixed-price	contracts,	we	receive	a	fixed	price	regardless	of	the	actual	costs	we	incur.	We	have	to	absorb	any	costs	in	excess of	the	fixed	price.	Under	time-and-materials	contracts,	we	are	paid	for	labor	at	negotiated	hourly	billing	rates	and	for	certain	expenses.

The	failure	to	perform	to	customer	expectations	and	contract	requirements	may	result	in	reduced	fees	or	losses	and	affect	our	financial	performance	in	that	period. Under	each	type	of	contract,	if	we	are	unable	to	control	costs,	our	operating	results	could	be	adversely	affected,	particularly	if	we	are	unable	to	justify	an	increase	in contract	value	to	our	customers.	Cost	overruns	or	the	failure	to	perform	on	existing	programs	also	may	adversely	affect	our	ability	to	retain	existing	programs	and	win future	contract	awards.

The	U.S.	Government	is	currently	pursuing	and	implementing	policies	that	could	negatively	impact	our	profitability.	Changes	in	procurement	policy	favoring	more incentive-based	 fee	 arrangements,	 different	 award	 fee	 criteria	 or	 government	 contract	 negotiation	 offers	 that	 indicate	 what	 our	 costs	 should	 be	 may	 affect	 the predictability	of	our	profit	rates.	Our	customers	are	subject	to	pressures	that	may	result	in	a	change	in	contract	types	referenced	above	earlier	in	a	program's	maturity than	is	traditional.	An	example	of	this	is	the	use	of	fixed-price	incentive-fee	contracts	for	recent	LRIP	contracts	on	the	F-35	program	while	the	development	contract	is being	performed	concurrently.	Our	customers	also	may	pursue	non-

traditional	contract	provisions	in	negotiation	of	contracts.	For	example,	changes	resulting	from	the	F-35	development	contract	may	need	to	be	implemented	on	the production	contracts,	a	concept	referred	to	as	concurrency,	which	may	require	us	to	pay	for	a	portion	of	the	concurrency	costs.	An	example	of	customer	budget	pressures includes	the	U.S.	Government	requiring	that	bid	and	proposal	costs	be	included	in	general	and	administrative	costs,	rather	than	charged	directly	to	contracts	in	certain circumstances.

Other	policies	could	negatively	impact	our	working	capital	and	cash	flow.	For	example,	the	government	has	expressed	a	preference	for	requiring	progress	payments rather	than	performance	based	payments	on	new	fixed-price	contracts,	which	if	implemented,	delays	our	ability	to	recover	a	significant	amount	of	costs	incurred	on	a contract	and	thus	affects	the	timing	of	our	cash	flows.

# Increased	competition	and	bid	protests	in	a	budget-constrained	environment	may	make	it	more	difficult	to	maintain	our	financial	performance	and	customer relationships.

We	are	facing	increased	competition,	particularly	in	information	technology	at	our	IS&GS	business	segment	and	cybersecurity	at	our	MST	business	segment,	from non-traditional	competitors	outside	of	the	aerospace	and	defense	industry.	At	the	same	time,	our	customers	are	facing	budget	constraints,	trying	to	do	more	with	less	by cutting	costs,	identifying	more	affordable	solutions,	performing	certain	work	internally	rather	than	hiring	a	contractor,	and	reducing	product	development	cycles.	We have	also	experienced	increased	market	pressures	in	our	services	businesses	due	to	the	fragmentation	of	large	contracts	into	multiple	smaller	contracts	that	are	awarded primarily	on	the	basis	of	price.	It	is	critical	we	maintain	strong	customer	relationships	and	seek	to	understand	the	priorities	of	their	requirements	in	this	price	competitive environment.

In	international	sales,	we	face	substantial	competition	from	both	U.S.	manufacturers	and	international	manufacturers	whose	governments	sometimes	provide research	and	development	assistance,	marketing	subsidies	and	other	assistance	for	their	products.	Additionally,	our	competitors	are	also	focusing	on	increasing	their international	 sales	 to	 partially	 mitigate	 the	 effect	 of	 reduced	 U.S.	 Government	 budgets.	To	 remain	 competitive,	 we	 consistently	 must	 maintain	 strong	 customer relationships	and	provide	superior	performance,	advanced	technology	solutions	and	service	at	an	affordable	cost	and	with	the	agility	that	our	customers	require	to	satisfy their	mission	objectives.

A	substantial	portion	of	our	business	is	awarded	through	competitive	bidding.	The	U.S.	Government	increasingly	has	relied	upon	competitive	contract	award	types, including	indefinite-delivery,	indefinite-quantity,	GSA	Schedule	and	other	multi-award	contracts,	which	has	the	potential	to	create	pricing	pressure	and	increase	our	cost by	requiring	that	we	submit	multiple	bids	and	proposals.	In	addition,	multi-award	contracts	require	that	we	make	sustained	efforts	to	obtain	task	orders	under	the contract.	The	competitive	bidding	process	entails	substantial	costs	and	managerial	time	to	prepare	bids	and	proposals	for	contracts	that	may	not	be	awarded	to	us	or	may be	split	among	competitors.	Following	award,	we	may	encounter	significant	expenses,	delays,	contract	modifications	or	bid	protests	from	unsuccessful	bidders	on	new program	awards.	Unsuccessful	bidders	are	more	frequently	protesting	in	the	hope	of	being	awarded	a	subcontract	for	a	portion	of	the	work	in	return	for	withdrawing	the protest.	Bid	protests	could	result	in	significant	expenses	to	us,	contract	modifications	or	even	loss	of	the	contract	award.	Even	where	a	bid	protest	does	not	result	in	the loss	of	a	contract	award,	the	resolution	can	extend	the	time	until	the	contract	activity	can	begin	and,	as	a	result,	delay	our	recognizing	sales.	We	also	may	not	be successful	in	our	efforts	to	protest	or	challenge	any	bids	for	contracts	that	were	not	awarded	to	us	and	we	could	incur	significant	time	and	expense	in	such	efforts.

# We	are	the	prime	contractor	on	most	of	our	contracts	and	if	our	subcontractors,	suppliers	or	teaming	agreement	or	venture	partners	fail	to	perform	their obligations,	our	performance	and	our	ability	to	win	future	business	could	be	harmed.

For	most	of	our	contracts	we	rely	on	other	companies	to	provide	materials,	major	components	and	products,	and	to	perform	a	portion	of	the	services	that	we	provide to	our	customers.	Such	arrangements	may	involve	subcontracts,	teaming	arrangements,	ventures	or	supply	agreements	with	other	companies	upon	which	we	rely (contracting	parties).	There	is	a	risk	that	we	may	have	disputes	with	our	contracting	parties,	including	disputes	regarding	the	quality	and	timeliness	of	work	performed, the	workshare	provided	to	that	party,	customer	concerns	about	the	other	party's	performance,	our	failure	to	extend	existing	task	orders	or	issue	new	task	orders,	or	our hiring	the	personnel	of	a	subcontractor,	teammate	or	venture	partner	or	vice	versa.	In	addition,	changes	in	the	economic	environment,	including	defense	budgets	and constraints	on	available	financing,	may	adversely	affect	the	financial	stability	of	our	contracting	parties	and	their	ability	to	meet	their	performance	requirements	or	to provide	needed	supplies	on	a	timely	basis.	A	failure,	for	whatever	reason,	by	one	or	more	of	our	contracting	parties	to	provide	the	agreed-upon	supplies	or	perform	the agreed-upon	services	on	a	timely	basis	may	affect	our	ability	to	perform	our	obligations	and	require	that	we	transition	the	work	to	other	companies.	Contracting	party

performance	deficiencies	may	affect	our	operating	results	and	could	result	in	a	customer	terminating	our	contract	for	default	or	convenience.	A	default	termination	could expose	us	to	liability	and	affect	our	ability	to	compete	for	future	contracts	and	orders.	Additionally,	our	efforts	to	increase	the	efficiency	of	our	operations	and	improve the	affordability	of	our	products	and	services	could	negatively	impact	our	ability	to	attract	and	retain	suppliers.

# International	sales	may	pose	different	risks.

In	2015,	21%	of	our	total	net	sales	were	from	international	customers.	We	have	a	strategy	to	grow	international	sales	over	the	next	several	years,	inclusive	of	sales of	F-35	aircraft	to	our	international	partners	and	other	countries.	International	sales	are	subject	to	numerous	political	and	economic	factors,	regulatory	requirements, significant	competition	and	other	risks	associated	with	doing	business	in	foreign	countries.	Our	exposure	to	such	risks	increased	as	a	result	of	our	acquisition	of	Sikorsky and	may	further	increase	if	our	international	sales	grow	as	we	anticipate.

Our	international	business	is	conducted	through	foreign	military	sales	(FMS)	contracted	through	the	U.S.	Government	or	by	direct	commercial	sales	(DCS)	with international	customers.	In	2015,	approximately	62%	of	our	sales	to	international	customers	were	FMS	and	about	38%	were	DCS.	These	transaction	types	differ	as	FMS transactions	represent	sales	by	the	U.S.	Government	to	international	governments	and	our	contract	with	the	U.S.	Government	is	subject	to	FAR.	By	contrast,	DCS transactions	represent	sales	directly	to	another	international	government	or	commercial	customer.	All	sales	to	international	customers	are	subject	to	U.S.	and	foreign	laws and	regulations,	including,	without	limitation,	regulations	relating	to	anti-corruption,	import-export	control,	technology	transfer	restrictions,	taxation,	repatriation	of earnings,	exchange	controls,	the	Foreign	Corrupt	Practices	Act	and	other	anti-corruption	laws,	and	the	anti-boycott	provisions	of	the	U.S.	Export	Administration	Act. While	we	have	stringent	policies	in	place	to	comply	with	such	laws	and	regulations,	failure	by	us,	our	employees	or	others	working	on	our	behalf	to	comply	with	these laws	and	regulations	could	result	in	administrative,	civil,	or	criminal	liabilities,	including	suspension,	debarment	from	bidding	for	or	performing	government	contracts, or	suspension	of	our	export	privileges,	which	could	have	a	material	adverse	effect	on	us.	We	frequently	team	with	international	subcontractors	and	suppliers	who	are also	exposed	to	similar	risks.

While	international	sales,	whether	contracted	as	FMS	or	DCS,	present	risks	that	are	different	and	potentially	greater	than	those	encountered	in	our	U.S.	business, DCS	with	international	customers	may	impose	even	greater	risks.	DCS	transactions	involve	commercial	relationships	with	parties	with	whom	we	have	less	familiarity and	where	there	may	be	significant	cultural	differences.	Additionally,	international	procurement	rules	and	regulations,	contract	laws	and	regulations,	and	contractual terms	differ	from	those	in	the	U.S.	and	are	less	familiar	to	us.	International	regulations	may	be	interpreted	by	foreign	courts	less	bound	by	precedent	and	with	more discretion;	these	interpretations	frequently	have	terms	less	favorable	to	us	than	the	FAR.	Export	and	import,	tax	and	currency	risk	also	may	be	increased	for	DCS	with international	customers.	While	these	risks	are	potentially	greater	than	those	encountered	in	our	U.S.	business,	the	pricing	of	our	products	and	services	is	commensurate with	the	risk	profile	on	DCS	with	international	customers.

Our	international	business	is	highly	sensitive	to	changes	in	regulations,	political	environments	or	security	risks	that	may	affect	our	ability	to	conduct	business outside	of	the	U.S.,	including	those	regarding	investment,	procurement,	taxation	and	repatriation	of	earnings.	Our	international	business	also	may	be	impacted	by changes	in	foreign	national	priorities,	foreign	government	budgets,	global	economic	conditions,	and	fluctuations	in	foreign	currency	exchange	rates.	Our	acquisition	of Sikorsky	is	expected	to	increase	our	international	sales	further	exposing	us	to	the	risks	of	international	business.	Sales	of	military	products	are	also	affected	by	defense budgets	and	U.S.	foreign	policy.	Additionally,	the	timing	of	orders	from	our	international	customers	can	be	less	predictable	than	for	our	U.S.	customers	and	may	lead	to fluctuations	in	the	amount	reported	each	year	for	our	international	sales.

In	conjunction	with	defense	procurements,	some	international	customers	require	contractors	to	comply	with	industrial	cooperation	regulations,	including	entering into	industrial	cooperation	agreements,	sometimes	referred	to	as	offset	agreements.	Offset	agreements	may	require	in-country	purchases,	technology	transfers,	local manufacturing	support,	investments	in	foreign	joint	ventures	and	financial	support	projects	as	an	incentive	or	as	a	condition	to	a	contract	award.	In	some	countries,	these offset	agreements	may	require	the	establishment	of	a	venture	with	a	local	company,	which	must	control	the	venture.	The	costs	to	satisfy	our	offset	obligations	are included	in	the	estimates	of	our	total	costs	to	complete	the	contract	and	may	impact	our	profitability	and	cash	flows.	The	ability	to	recover	investments	that	we	make	is generally	dependent	upon	the	successful	operation	of	ventures	that	we	do	not	control	and	may	involve	products	and	services	that	are	dissimilar	to	our	business	activities. In	these	and	other	situations,	we	could	be	liable	for	violations	of	law	for	actions	taken	by	these	entities	such	as	laws	related	to	anti-corruption,	import	and	export,	and anti-boycott	restrictions.	Offset	agreements	generally	extend	over	several	years	and	may	provide	for	penalties	in	the	event	we	fail	to	perform	in	accordance	with	the offset	requirements	which	are	typically	subjective	and	can	be	outside	our	control.

# Our	business	could	be	negatively	affected	by	cyber	or	other	security	threats	or	other	disruptions.

We	routinely	experience	cybersecurity	threats,	threats	to	our	information	technology	infrastructure,	and	unauthorized	attempts	to	gain	access	to	our	company sensitive	information,	as	do	our	customers,	suppliers,	subcontractors	and	venture	partners.	We	may	experience	similar	security	threats	at	customer	sites	that	we	operate and	manage	as	a	contractual	requirement.

Prior	cyberattacks	directed	at	us	have	not	had	a	material	impact	on	our	financial	results	and	we	believe	our	threat	detection	and	mitigation	processes	and	procedures are	adequate.	The	threats	we	face	vary	from	attacks	common	to	most	industries	to	more	advanced	and	persistent,	highly	organized	adversaries	who	target	us	because	we protect	national	security	information.	If	we	are	unable	to	protect	sensitive	information,	our	customers	or	governmental	authorities	could	question	the	adequacy	of	our threat	mitigation	and	detection	processes	and	procedures.	Due	to	the	evolving	nature	of	these	security	threats,	the	impact	of	any	future	incident	cannot	be	predicted.

Although	we	work	cooperatively	with	our	customers,	suppliers,	subcontractors,	venture	partners	and	acquisitions	to	seek	to	minimize	the	impact	of	cyber	threats, other	security	threats,	or	business	disruptions,	we	must	rely	on	the	safeguards	put	in	place	by	these	entities,	which	may	affect	the	security	of	our	information.	These entities	have	varying	levels	of	cybersecurity	expertise	and	safeguards,	and	their	relationships	with	government	contractors,	such	as	Lockheed	Martin,	may	increase	the likelihood	that	they	are	targeted	by	the	same	cyber	threats	we	face.

On	July	9,	2015,	the	U.S.	Office	of	Personnel	Management	(OPM)	announced	that	the	background	investigation	records	of	21.5	million	current,	former	and prospective	Federal	employees	and	contractors	had	been	compromised	as	a	result	of	a	cyber-security	incident.	Many	of	our	current	as	well	as	former	employees	were	the subjects	of	background	investigations	in	connection	with	former	government	service	or	as	part	of	the	screening	process	for	a	security	clearance.	We	are	currently assessing	the	impact	of	this	cyber-security	incident	but	do	not	yet	know	the	impact,	if	any,	on	Lockheed	Martin	or	our	current	or	former	employees.

The	costs	related	to	cyber	or	other	security	threats	or	disruptions	may	not	be	fully	insured	or	indemnified	by	other	means.	Additionally,	some	cyber	technologies	we develop	under	contract	for	our	customers,	particularly	those	related	to	homeland	security,	may	raise	potential	liabilities	related	to	intellectual	property	and	civil	liberties, including	privacy	concerns,	which	may	not	be	fully	insured	or	indemnified	by	other	means.	Occurrence	of	any	of	these	events	could	adversely	affect	our	internal operations,	the	services	we	provide	to	our	customers,	our	future	financial	results,	our	reputation,	or	our	stock	price.	Additionally,	such	events	could	result	in	the	loss	of competitive	advantages	derived	from	our	research	and	development	efforts	or	other	intellectual	property;	early	obsolescence	of	our	products	and	services;	or	contractual penalties.

# If	we	fail	to	manage	acquisitions,	divestitures,	equity	investments	and	other	transactions	successfully	or	if	acquired	entities	or	equity	investments	fail	to perform	as	expected,	our	financial	results,	business	and	future	prospects	could	be	harmed.

In	pursuing	our	business	strategy,	we	routinely	conduct	discussions,	evaluate	companies,	and	enter	into	agreements	regarding	possible	acquisitions,	divestitures, ventures	and	equity	investments.	We	seek	to	identify	acquisition	or	investment	opportunities	that	will	expand	or	complement	our	existing	products	and	services	or customer	base,	at	attractive	valuations.	We	often	compete	with	others	for	the	same	opportunities.	To	be	successful,	we	must	conduct	due	diligence	to	identify	valuation issues	and	potential	loss	contingencies;	negotiate	transaction	terms;	complete	and	close	complex	transactions;	integrate	acquired	companies	and	employees;	and	realize anticipated	operating	synergies	efficiently	and	effectively.	Acquisition,	divestiture,	venture	and	investment	transactions	often	require	substantial	management	resources and	have	 the	potential	 to	divert	our	attention	from	our	existing	business.	Unidentified	pre-closing	 liabilities	could	affect	our	future	financial	results,	particularly successor	liability	under	procurement	laws	and	regulations	such	as	the	False	Claims	Act	or	Truth	in	Negotiations	Act,	anti-corruption,	tax,	import-export	and	technology transfer	laws	which	provide	for	civil	and	criminal	penalties	and	the	potential	for	debarment.	We	also	may	incur	unanticipated	costs	or	expenses,	including	post-closing asset	impairment	charges,	expenses	associated	with	eliminating	duplicate	facilities,	employee	retention,	transaction-related	or	other	litigation,	and	other	liabilities.	Any of	the	foregoing	could	adversely	affect	our	business	and	results	of	operations.

Ventures,	or	non-controlling	equity	investments,	operate	under	shared	control	with	other	parties.	Under	the	equity	method	of	accounting	for	nonconsolidated ventures	and	investments,	we	recognize	our	share	of	the	operating	profit	of	these	ventures	in	our	results	of	operations.	Our	operating	results	may	be	affected	by	the performance	of	businesses	over	which	we	do	not	exercise	control	and	which	face	many	of	the	same	risks	and	uncertainties	as	we	do.	The	most	significant	impact	of	our

equity	investments	is	in	our	Space	Systems	business	segment	where	approximately	21%	of	its	2015	operating	profit	was	derived	from	its	share	of	earnings	from	equity method	investees,	particularly	that	in	United	Launch	Alliance	(ULA).

Our	ULA	investment	may	be	negatively	impacted	by	restrictions	in	the	National	Defense	Authorization	Act	for	Fiscal	Year	2015	that	prevent	the	award	or	renewal of	contracts	after	December	29,	2014	for	evolved	expendable	launch	vehicle	services	that	utilize	a	rocket	engine	designed	or	manufactured	in	the	Russian	Federation such	as	the	RD-180	engine	used	by	the	Atlas	V	launch	vehicle.	The	Consolidated	Appropriations	Act	of	2016	lifts	these	restrictions	for	fiscal	year	2016.	Accordingly, Lockheed	Martin	does	not	anticipate	an	impact	on	the	carrying	value	of	its	equity	investment	in	ULA	in	2016.	If	restrictions	are	re-imposed	for	fiscal	year	2016,	as some	in	Congress	advocate,	or	the	lifting	of	the	restrictions	is	not	extended	to	later	fiscal	years,	or	if	sanctioned	individuals	are	found	to	be	too	closely	connected	to	the engine	manufacturer,	ULA	will	be	challenged	to	compete	effectively	for	national	security	launch	procurements	which	could	negatively	impact	ULA	and	the	carrying value	of	our	investment	in	ULA.	ULA	continues	to	evaluate	domestic	engine	alternatives	and	we	will	continue	to	monitor	the	carrying	value	of	our	investment.

The	acquired	Sikorsky	business	may	underperform	relative	to	our	expectations,	the	transaction	may	cause	our	financial	results	to	differ	from	our	expectations or	the	expectations	of	the	investment	community	and	we	may	not	be	able	to	achieve	anticipated	cost	savings	or	other	anticipated	synergies.

On	November	6,	2015,	we	completed	the	acquisition	of	Sikorsky	Aircraft	Corporation	(Sikorsky)	by	purchasing	all	of	the	issued	and	outstanding	equity	of	Sikorsky for	$9.0	billion,	net	of	cash	acquired.	We	believe	that	we	will	benefit	from	the	integration	of	our	products	and	technologies	with	those	of	the	Sikorsky	business	and realize	synergies	and	potential	for	long-term	growth,	as	well	as	expanded	capabilities	and	customer	relationships	as	a	result	of	the	acquisition.	However,	the	integration process	is	complex,	costly	and	time-consuming	and	we	may	not	be	able	to	capture	anticipated	synergies,	tax	benefits,	cost	savings,	and	business	opportunities	in	the	time frame	anticipated,	or	at	all.	Sikorsky	also	may	not	perform	as	expected,	or	demand	for	its	products	may	be	adversely	affected	by	global	economic	conditions,	including oil	and	gas	trends	that	are	outside	of	its	control.	The	acquisition	could	also	cause	disruptions	in	our	and	Sikorsky's	business,	including	potential	adverse	reactions	or changes	to	business	relationships	and	competitive	responses.	The	DoD	has	expressed	concerns	regarding	greater	consolidation	in	the	defense	industry	at	the	prime contractor	level	in	the	context	of	our	acquisition	of	Sikorsky	and	indicated	the	potential	that	they	will	seek	to	work	with	Congress	to	explore	additional	legal	tools	and policy	to	preserve	diversity	at	the	prime	contract	level.	Changes	in	DoD	policy	or	perception	of	our	size	could	have	adverse	impacts	on	our	business,	including	our success	in	future	contract	pursuits.	Any	of	the	foregoing	could	adversely	affect	our	business,	financial	condition	and	results	of	operations.

We	are	pursuing	a	plan	to	separate	and	combine	our	government	information	technology	and	technical	services	businesses	with	Leidos,	Holdings,	Inc.	in	a	tax- efficient	Reverse	Morris	Trust	transaction.	The	proposed	transaction	may	not	be	completed	on	the	currently	contemplated	timeline	or	at	all	and	may	not achieve	the	intended	benefits.

On	January	26,	2016,	we	entered	into	definitive	agreements	to	separate	and	combine	our	Information	Systems	&	Global	Solutions	(IS&GS)	business	segment	with Leidos	Holdings,	Inc.	(Leidos)	in	a	tax-efficient	Reverse	Morris	Trust	transaction.	As	part	of	the	transaction,	we	will	receive	a	$1.8	billion	one-time	special	cash payment.	The	cash	payment	is	subject	to	adjustment	and	could	be	less	or	more	than	anticipated	due	to	variances	in	working	capital.	Additionally,	our	stockholders	will receive	approximately	50.5	percent	of	the	outstanding	equity	of	Leidos	on	a	fully	diluted	basis	(approximately	77	million	shares)	with	an	estimated	value	of	$3.2	billion based	on	Leidos'	stock	price	on	the	date	of	announcement.	However,	the	actual	value	of	the	stock	to	be	received	by	our	stockholders	will	depend	on	the	value	of	such shares	at	the	time	of	closing	of	the	transaction	and	our	stockholders	may	receive	more	or	less	than	the	anticipated	value.	At	our	election,	the	distribution	may	be	effected by	means	of	a	pro	rata	dividend	in	a	spin-off	transaction	or	in	an	exchange	offer	for	outstanding	Lockheed	Martin	shares	in	a	split-off	transaction.	The	transaction structure,	which	is	subject	to	market	conditions,	is	currently	contemplated	to	be	a	split-off	transaction	resulting	in	a	decrease	in	our	outstanding	common	shares	and	a significant	book	gain	at	closing.	In	a	split-off	transaction,	only	those	stockholders	that	elect	to	participate	will	receive	Leidos	shares	in	the	merger	transaction,	provided, that,	if	the	exchange	offer	is	not	fully	subscribed,	Lockheed	Martin	will	spin-off	the	remaining	shares	to	be	converted	into	Leidos	stock	in	the	merger	pro	rata.	The	value of	the	shares	of	Leidos	stock	to	be	received	and	the	value	of	our	stock	at	the	time	of	the	split-off	will	also	impact	the	number	of	any	shares	of	our	stock	retired	in	the split-off	and	the	amount	of	any	book	gain.	Although	the	transaction	structure	is	currently	contemplated	to	be	a	split-off	transaction,	there	is	no	assurance	that	the transaction	will	be	structured	as	a	split-off	transaction	or	that	it	will	result	in	a	reduction	in	our	shares	or	a	gain	at	closing.

There	can	be	no	assurance	of	the	timing	of	a	transaction	with	Leidos,	or	whether	any	such	transaction	will	take	place	at	all.	The	transaction	is	subject	to	closing conditions,	including	the	receipt	of	approval	of	Leidos	stockholders,	regulatory	approvals	and	receipt	of	opinions	of	tax	counsel,	and	there	can	be	no	assurance	that	we will	receive	the	required	approvals	in

a	timely	manner	or	at	all,	or	that	such	approvals	will	not	contain	adverse	conditions.	We	also	have	no	assurance	that	we	will	be	able	to	realize	the	intended	benefits	and tax	treatment	of	the	transaction	or	that	the	new	combined	company	will	perform	as	expected.	The	announcement	and	pendency	of	the	transaction	could	also	cause disruptions	in	our	and	Leidos'	business,	including	potential	adverse	reactions	or	changes	to	business	relationships	and	competitive	responses	to	the	transaction.	The transaction	will	also	require	significant	amounts	of	time	and	effort	which	could	divert	management's	attention	from	operating	and	growing	our	business.	Any	of	the foregoing	could	adversely	affect	our	business,	financial	condition	and	results	of	operations.	Declines	in	our	sales,	earnings	and	cash	flows	could	also	result	in	future asset	impairments	(including	goodwill).	Additionally,	the	former	IS&GS	programs	we	moved	to	our	other	business	segments	and	retained	could	experience	increased pricing	pressures	which	could	have	a	negative	impact	on	operating	margins	and	impact	our	ability	to	win	future	renewals.

In	addition,	as	part	of	the	transaction	with	Leidos,	it	is	contemplated	that	immediately	prior	to	the	transaction,	the	IS&GS	business	would	enter	into	third-party financing	in	an	aggregate	principal	amount	of	approximately	$1.8	billion	to	finance	the	$1.8	billion	special	cash	payment	and	the	payment	of	certain	fees	and	expenses. The	IS&GS	business	(through	a	subsidiary	created	for	the	transaction)	has	entered	into	a	commitment	letter	(the	"Commitment	Letter")	with	certain	financial	institutions to	provide	this	financing	through	$710	million	of	Term	Loan	A	facilities	and	a	$1.13	billion	Term	Loan	B	facility.	Under	the	terms	of	the	Commitment	Letter,	if	the closing	does	not	occur	by	July	26,	2016,	the	lenders	(in	consultation	with	us)	could	require	the	IS&GS	business	subsidiary	to	borrow	up	to	the	full	amount	of	the	Term Loan	B	facility	in	advance	of	the	closing	of	the	transaction	(the	"Loan	Demand")	and	deposit	the	proceeds	of	such	borrowing	in	escrow	to	secure	such	loan,	which	would increase	our	total	outstanding	debt	for	the	period	from	the	date	the	Loan	Demand	is	exercised	until	closing	of	the	transaction.	If	the	closing	of	the	transaction	were	not	to occur	and	our	agreement	with	Leidos	was	terminated,	we	would	cause	the	IS&GS	business	to	repay	any	amounts	borrowed	and	would	be	entitled	to	reimbursement	for financing	costs	from	Leidos	under	the	term	of	our	agreement	with	Leidos.

# Our	business	involves	significant	risks	and	uncertainties	that	may	not	be	covered	by	indemnity	or	insurance.

A	significant	portion	of	our	business	relates	to	designing,	developing	and	manufacturing	advanced	defense	and	technology	products	and	systems.	New	technologies may	be	untested	or	unproven.	Failure	of	some	of	these	products	and	services	could	result	in	extensive	loss	of	life	or	property	damage.	Accordingly,	we	also	may	incur liabilities	that	are	unique	to	our	products	and	services,	including	combat	and	air	mobility	aircraft,	missile	and	space	systems,	command	and	control	systems,	air	traffic control	management	systems,	cybersecurity,	homeland	security	and	training	programs.	In	some	but	not	all	circumstances,	we	may	be	entitled	to	certain	legal	protections or	indemnifications	from	our	customers,	either	through	U.S.	Government	indemnifications	under	Public	Law	85-804	or	the	Price-Anderson	Act,	qualification	of	our products	and	services	by	the	Department	of	Homeland	Security	under	the	SAFETY	Act	provisions	of	the	Homeland	Security	Act	of	2002,	contractual	provisions	or otherwise.	We	endeavor	to	obtain	insurance	coverage	from	established	insurance	carriers	to	cover	these	risks	and	liabilities.	The	amount	of	insurance	coverage	that	we maintain	may	not	be	adequate	to	cover	all	claims	or	liabilities.	Existing	coverage	may	be	cancelled	while	we	remain	exposed	to	the	risk,	and	it	is	not	possible	to	obtain insurance	to	protect	against	all	operational	risks	and	liabilities.	For	example,	we	are	limited	in	the	amount	of	insurance	we	can	obtain	to	cover	certain	natural	hazards, such	as	earthquakes.	We	have	significant	operations	in	geographic	areas	prone	to	this	risk,	such	as	Sunnyvale,	California.	Even	if	insurance	coverage	is	available,	we may	not	be	able	to	obtain	it	at	a	price	or	on	terms	acceptable	to	us.	Additionally,	disputes	with	insurance	carriers	over	coverage	terms	or	the	insolvency	of	one	or	more	of our	insurance	carriers	may	significantly	affect	the	amount	or	timing	of	our	cash	flows.

Substantial	costs	resulting	from	an	accident;	failure	of	or	defect	in	our	products	or	services;	natural	catastrophe	or	other	incident;	or	liability	arising	from	our products	and	services	in	excess	of	any	legal	protection,	indemnity,	and	our	insurance	coverage	(or	for	which	indemnity	or	insurance	is	not	available	or	not	obtained) could	adversely	impact	our	financial	condition,	cash	flows,	or	operating	results.	Any	accident,	failure	of,	or	defect	in	our	products	or	services,	even	if	fully	indemnified or	insured,	could	negatively	affect	our	reputation	among	our	customers	and	the	public	and	make	it	more	difficult	for	us	to	compete	effectively.	It	also	could	affect	the cost	and	availability	of	adequate	insurance	in	the	future.

# Pension	funding	and	costs	are	dependent	on	several	economic	assumptions	which if	changed	may	cause	our	future	earnings	and	cash	flow	to	fluctuate significantly	as	well	as	affect	the	affordability	of	our	products	and	services.

Many	of	our	employees	are	covered	by	defined	benefit	pension	plans,	and	we	provide	certain	health	care	and	life	insurance	benefits	to	eligible	retirees.	The	impact of	these	plans	on	our	U.S.	generally	accepted	accounting	principles	(GAAP)	earnings	may	be	volatile	in	that	the	amount	of	expense	we	record	for	our	postretirement benefit	 plans	 may	 materially	 change	 from	 year	 to	 year	 because	 those	 calculations	 are	 sensitive	 to	 funding	 levels	 as	 well	 as	 changes	 in	 several	 key	 economic assumptions,	including	interest	rates,	rates	of	return	on	plan	assets,	and	other	actuarial	assumptions	including	participant	longevity	(also	known	as	mortality),	employee turnover,	as	well	as	the	timing	of	cash	funding.	Changes	in	these

factors,	including	actual	returns	on	plan	assets,	may	also	affect	our	plan	funding,	cash	flow	and	stockholders'	equity.	In	addition,	the	funding	of	our	plans	and	recovery of	costs	on	our	contracts,	as	described	below,	also	may	be	subject	to	changes	caused	by	legislative	or	regulatory	actions.	We	have	taken	certain	actions	over	the	last	few years	to	mitigate	the	volatility	the	plans	may	have	on	our	cash	flows	and	earnings,	including	amendments	made	in	June	2014	to	certain	of	our	qualified	and	nonqualified defined	benefit	pension	plans	for	non-union	employees	to	freeze	future	retirement	benefits.	However,	the	impact	of	these	actions	on	our	cash	flow	and	earnings	may	be less	than	anticipated	or	may	be	offset	by	other	factors	such	as	changes	in	actuarial	assumptions	and	plan	asset	investment	returns.

With	regard	to	cash	flow,	we	have	made	substantial	cash	contributions	to	our	plans	in	excess	of	the	amounts	required	by	the	Employee	Retirement	Income	Security Act	of	1974	(ERISA),	as	amended	by	the	Pension	Protection	Act	of	2006	(PPA).	We	generally	are	able	to	recover	these	contributions	related	to	our	plans	as	allowable costs	on	our	U.S.	Government	contracts,	including	FMS,	but	there	is	a	lag	between	when	we	contribute	cash	to	our	plans	under	pension	funding	rules	and	recover	it under	U.S.	Government	Cost	Accounting	Standards	(CAS).	Effective	February	2012,	the	CAS	rules	were	revised	to	harmonize	the	measurement	and	period	assignment of	the	pension	cost	allocable	to	government	contracts	with	the	PPA	(CAS	Harmonization).	In	2013,	the	cost	impact	of	CAS	Harmonization	started	being	phased	in	with the	goal	of	better	aligning	the	CAS	pension	cost	and	ERISA	funding	requirements	being	fully	achieved	in	2017.	The	enactment	of	the	Highway	and	Transportation Funding	Act	of	2014	and	Bipartisan	Budget	Act	of	2015	increased	the	interest	rate	assumption	used	to	determine	our	CAS	pension	costs,	which	has	the	effect	of lowering	the	recovery	of	pension	contributions	during	the	affected	periods	as	it	decreases	our	CAS	pension	costs.

For	more	 information	on	how	 these	factors	could	 impact	earnings,	financial	position,	cash	flow	and	stockholders'	equity,	see	"Critical	Accounting	Policies –	Postretirement	Benefit	Plans"	in	Management's	Discussion	and	Analysis	of	Financial	Conditions	and	Results	of	Operations	and	"Note	11	–	Postretirement	Plans"	of our	consolidated	financial	statements.

# Environmental	costs	could	affect	our	future	earnings	as	well	as	the	affordability	of	our	products	and	services.

Our	operations	are	subject	to	and	affected	by	a	variety	of	federal,	state,	local	and	foreign	environmental	protection	laws	and	regulations.	We	are	involved	in environmental	responses	at	some	of	our	facilities,	former	facilities,	and	at	third-party	sites	not	owned	by	us	where	we	have	been	designated	a	potentially	responsible party.	In	addition,	we	could	be	affected	by	future	regulations	imposed	or	claims	asserted	in	response	to	concerns	over	climate	change,	other	aspects	of	the	environment	or natural	resources.	We	have	an	ongoing	comprehensive	sustainability	program	to	reduce	the	effects	of	our	operations	on	the	environment.

We	manage	various	government-owned	facilities	on	behalf	of	the	government.	At	such	facilities,	environmental	compliance	and	remediation	costs	historically	have been	the	responsibility	of	the	government,	and	we	have	relied,	and	continue	to	rely	with	respect	to	past	practices,	upon	government	funding	to	pay	such	costs.	Although the	government	remains	responsible	for	capital	and	operating	costs	associated	with	environmental	compliance,	responsibility	for	fines	and	penalties	associated	with environmental	noncompliance	typically	is	borne	by	either	the	government	or	the	contractor,	depending	on	the	contract	and	the	relevant	facts.	Some	environmental	laws include	criminal	provisions.	An	environmental	law	conviction	could	affect	our	ability	to	be	awarded	future,	or	perform	existing,	U.S.	Government	contracts.

We	have	incurred	and	will	continue	to	incur	liabilities	under	various	federal,	state,	local	and	foreign	statutes	for	environmental	protection	and	remediation.	The extent	of	our	financial	exposure	cannot	in	all	cases	be	reasonably	estimated	at	this	time.	Among	the	variables	management	must	assess	in	evaluating	costs	associated with	these	cases	and	remediation	sites	generally	are	the	status	of	site	assessment,	extent	of	the	contamination,	impacts	on	natural	resources,	changing	cost	estimates, evolution	of	technologies	used	to	remediate	the	site,	and	continually	evolving	governmental	environmental	standards	and	cost	allowability	issues.	For	information regarding	these	matters,	including	current	estimates	of	the	amounts	that	we	believe	are	required	for	remediation	or	cleanup	to	the	extent	probable	and	estimable,	see "Critical	Accounting	Policies	–	Environmental	Matters"	in	Management's	Discussion	and	Analysis	of	Financial	Condition	and	Results	of	Operations	and	"Note	14 –	Legal	Proceedings,	Commitments	and	Contingencies"	of	our	consolidated	financial	statements.

# We	are	involved	in	a	number	of	legal	proceedings.	We	cannot	predict	the	outcome	of	litigation	and	other	contingencies	with	certainty.

Our	business	may	be	adversely	affected	by	the	outcome	of	legal	proceedings	and	other	contingencies	that	cannot	be	predicted	with	certainty.	As	required	by GAAP,	we	estimate	loss	contingencies	and	establish	reserves	based	on	our	assessment	of	contingencies	where	liability	is	deemed	probable	and	reasonably	estimable	in light	of	the	facts	and	circumstances	known	to	us	at	a	particular	point	in	time.	Subsequent	developments	in	legal	proceedings	may	affect	our

assessment	and	estimates	of	the	loss	contingency	recorded	as	a	liability	or	as	a	reserve	against	assets	in	our	financial	statements.	For	a	description	of	our	current	legal proceedings,	see	Item	3	–	Legal	Proceedings	and	"Note	14	–	Legal	Proceedings,	Commitments	and	Contingencies"	of	our	consolidated	financial	statements.

# Our	success	depends,	in	part,	on	our	ability	to	maintain	a	qualified	workforce.

Due	to	the	specialized	nature	of	our	business,	our	future	performance	is	highly	dependent	upon	our	ability	to	maintain	a	workforce	with	the	requisite	skills	in multiple	 areas	 including:	 engineering,	 science,	 manufacturing,	 information	 technology,	 cybersecurity,	 business	 development	 and	 strategy	 and	 management.	 Our operating	performance	is	also	dependent	upon	personnel	who	hold	security	clearances	and	receive	substantial	training	in	order	to	work	on	certain	programs	or	tasks. Additionally,	 as	 we	 expand	 our	 operations	 internationally,	 it	 will	 be	 increasingly	 important	 to	 hire	 and	 retain	 personnel	 with	 relevant	 experience	 in	 local	 laws, regulations,	customs,	traditions	and	business	practices.

We	face	a	number	of	challenges	that	may	affect	personnel	retention	such	as	our	endeavors	to	increase	the	efficiency	of	our	operations	and	improve	the	affordability of	our	products	and	services	such	as	workforce	reductions	and	consolidating	and	relocating	certain	operations.	Additionally,	our	workforce	demographic	continues	to shift	toward	a	higher	proportion	of	employees	nearing	retirement.	In	June	2014,	we	amended	certain	of	our	defined	benefit	pension	plans	for	non-union	employees	to freeze	future	retirement	benefits,	which	may	encourage	retirement-eligible	personnel	to	elect	to	retire	earlier	than	anticipated.

To	the	extent	that	we	lose	experienced	personnel,	it	is	critical	that	we	develop	other	employees,	hire	new	qualified	personnel,	and	successfully	manage	the	transfer of	critical	knowledge.	Competition	for	personnel	is	intense,	and	we	may	not	be	successful	in	hiring	or	retaining	personnel	with	the	requisite	skills	or	clearances.	We increasingly	compete	with	commercial	technology	companies	outside	of	the	aerospace	and	defense	industry	for	qualified	technical,	cyber	and	scientific	positions	as	the number	of	qualified	domestic	engineers	is	decreasing	and	the	number	of	cyber	professionals	is	not	keeping	up	with	demand.	To	the	extent	that	these	companies	grow	at a	faster	rate	or	face	fewer	cost	and	product	pricing	constraints,	they	may	be	able	to	offer	more	attractive	compensation	and	other	benefits	to	candidates	or	our	existing employees.	To	the	extent	that	the	demand	for	skilled	personnel	exceeds	supply,	we	could	experience	higher	labor,	recruiting	or	training	costs	in	order	to	attract	and	retain such	employees;	we	could	experience	difficulty	in	performing	our	contracts	if	we	were	unable	to	do	so.	We	also	must	manage	leadership	development	and	succession planning	throughout	our	business.	While	we	have	processes	in	place	for	management	transition	and	the	transfer	of	knowledge,	the	loss	of	key	personnel,	coupled	with	an inability	to	adequately	train	other	personnel,	hire	new	personnel	or	transfer	knowledge,	could	significantly	impact	our	ability	to	perform	under	our	contracts.

Approximately	 18%	 of	 our	 employees	 are	 covered	 by	 collective	 bargaining	 agreements	 with	 various	 unions.	 Historically,	 where	 employees	 are	 covered	 by collective	bargaining	agreements	with	various	unions,	we	have	been	successful	in	negotiating	renewals	to	expiring	agreements	without	any	material	disruption	of operating	activities.	This	does	not	assure,	however,	that	we	will	be	successful	in	our	efforts	to	negotiate	renewals	of	our	existing	collective	bargaining	agreements	in	the future.	If	we	encounter	difficulties	with	renegotiations	or	renewals	of	collective	bargaining	arrangements	or	are	unsuccessful	in	those	efforts,	we	could	incur	additional costs	and	experience	work	stoppages.	Union	actions	at	suppliers	can	also	affect	us.	Any	delays	or	work	stoppages	could	adversely	affect	our	ability	to	perform	under	our contracts,	which	could	negatively	impact	our	results	of	operations,	cash	flows,	and	financial	condition.

# Our	estimates	and	projections	may	prove	to	be	inaccurate.

The	accounting	for	some	of	our	most	significant	activities	is	based	on	judgments	and	estimates,	which	are	complex	and	subject	to	many	variables.	For	example, accounting	for	sales	using	the	percentage-of-completion	method	requires	that	we	assess	risks	and	make	assumptions	regarding	schedule,	cost,	technical	and	performance issues	for	each	of	our	thousands	of	contracts,	many	of	which	are	long-term	in	nature.	Additionally,	we	initially	allocate	the	purchase	price	of	acquired	businesses	based on	a	preliminary	assessment	of	the	fair	value	of	identifiable	assets	acquired	and	liabilities	assumed.	The	size	and	breadth	of	significant	acquisitions,	such	as	Sikorsky, necessitate	the	use	of	a	one	year	measurement	period	to	adequately	analyze	and	assess	a	number	of	factors	used	in	establishing	the	asset	and	liability	fair	values	as	of	the acquisition	date	and	could	result	in	adjustments	to	asset	and	liability	balances,	including	changes	in	fair	values	of	contracts	assumed,	fixed	assets,	inventories	and deferred	revenue	and	changes	in	fair	values	of	intangible	assets	and	goodwill,	as	well	as	changes	to	the	amortization	periods	assigned	to	these	assets.	Any	potential adjustments	made	could	be	material	in	relation	to	the	preliminary	purchase	price	allocations	recorded	on	acquisition	dates.	Another	example	is	the	$13.6	billion	of goodwill	assets	recorded	on	our	Balance	Sheet	as	of	December	31,	2015	from	previous	acquisitions	which	represent	greater	than	27%	of	our	total	assets.	These	goodwill assets	are	subject	to	annual	impairment	testing	and	more	frequent	testing	upon	the	occurrence	of	certain

events	or	significant	changes	in	circumstances	that	indicate	goodwill	may	be	impaired.	If	we	experience	changes	or	factors	arise	that	negatively	affect	the	expected	cash flows	of	a	reporting	unit,	we	may	be	required	to	write	off	all	or	a	portion	of	the	reporting	unit's	related	goodwill	assets.

Changes	in	U.S.	or	foreign	tax	laws,	including	those	with	retroactive	effect,	and	audits	by	tax	authorities	could	result	in	unanticipated	increases	in	our	tax	expense and	affect	profitability	and	cash	flows.	For	example,	proposals	to	lower	the	U.S.	corporate	income	tax	rate	would	require	us	to	reduce	our	net	deferred	tax	assets	upon enactment	of	the	related	tax	legislation,	with	a	corresponding	material,	one-time	increase	to	income	tax	expense;	however,	our	income	tax	expense	and	payments	would be	materially	reduced	in	subsequent	years.

Actual	financial	results	could	differ	from	our	judgments	and	estimates.	Refer	to	"Critical	Accounting	Policies"	in	Management's	Discussion	and	Analysis	of Financial	Condition	and	Results	of	Operations	and	"Note	1	–	Significant	Accounting	Policies"	of	our	consolidated	financial	statements	for	a	complete	discussion	of	our significant	accounting	policies	and	use	of	estimates.

# ITEM	2. Properties.

At	December	31,	2015,	we	owned	or	leased	building	space	(including	offices,	manufacturing	plants,	warehouses,	service	centers,	laboratories	and	other	facilities) at	approximately	591	locations	primarily	in	the	U.S.	Additionally,	we	manage	or	occupy	various	U.S.	Government-owned	facilities	under	lease	and	other	arrangements.

At	December	31,	2015,	we	had	significant	operations	in	the	following	locations:

•	 Aeronautics	–	Palmdale,	California;	Marietta,	Georgia;	Greenville,	South	Carolina;	Fort	Worth	and	San	Antonio,	Texas;	and	Montreal,	Canada.

•Information	Systems	&	Global	Solutions	–	Gaithersburg,	Maryland.

•	 Missiles	and	Fire	Control	–	Camden,	Arkansas;	Orlando,	Florida;	and	Grand	Prairie,	Texas.

•	 Mission Systems and Training	–	 Stratford	 and	 Shelton,	 Connecticut;	 Colorado	 Springs,	 Colorado;	 Orlando	 and	 Jupiter,	 Florida;	 Baltimore,	 Maryland; Moorestown/Mt.

•	 Corporate	activities	–	Lakeland,	Florida;	and	Bethesda,	Maryland.

In	connection	with	the	acquisition	of	Sikorsky	Aircraft	Corporation,	we	assumed	6.5	million	square	feet	of	building	space.	However,	as	a	result	of	our	ongoing consolidation	efforts	we	reduced	our	overall	floor	space	by	2.1	million	square	feet	at	our	previously	owned	heritage	properties	in	2015.

The	following	is	a	summary	of	our	square	feet	of	floor	space	by	business	segment	at	December	31,	2015	(in	millions):

We	believe	our	facilities	are	in	good	condition	and	adequate	for	their	current	use.	We	may	improve,	replace	or	reduce	facilities	as	considered	appropriate	to	meet the	needs	of	our	operations.

# ITEM	3. Legal	Proceedings.

We	are	a	party	to	or	have	property	subject	to	litigation	and	other	proceedings	that	arise	in	the	ordinary	course	of	our	business,	including	matters	arising	under provisions	relating	to	the	protection	of	the	environment,	and	are	subject	to	contingencies	related	to	certain	businesses	we	previously	owned.	These	types	of	matters	could result	in	fines,	penalties,	compensatory	or	treble	damages	or	non-monetary	sanctions	or	relief.	We	believe	the	probability	is	remote	that	the	outcome	of	these	matters	will have	a	material	adverse	effect	on	the	Corporation	as	a	whole,	notwithstanding	that	the	unfavorable	resolution	of	any	matter	may	have	a	material	effect	on	our	net earnings	in	any	particular	interim	reporting	period.	We	cannot	predict	the	outcome	of	legal	or	other	proceedings	with	certainty.	These	matters	include	the	proceedings summarized	in	"Note	14	–	Legal	Proceedings,	Commitments	and	Contingencies"	of	our	consolidated	financial	statements.

We	are	subject	 to	federal,	state,	 local	and	foreign	requirements	for	protection	of	 the	environment,	 including	 those	for	discharge	of	hazardous	materials	and remediation	of	contaminated	sites.	As	a	result,	we	are	a	party	to	or	have	property	subject	to	various	lawsuits	or	proceedings	involving	environmental	protection	matters. Due	 in	part	 to	 their	complexity	and	pervasiveness,	such	requirements	have	resulted	 in	us	being	 involved	with	related	 legal	proceedings,	claims	and	remediation obligations.	The	extent	of	our	financial	exposure	cannot	in	all	cases	be	reasonably	estimated	at	this	time.	For	information	regarding	these	matters,	including	current estimates	of	the	amounts	that	we	believe	are	required	for	remediation	or	clean-up	to	the	extent	estimable,	see	"Critical	Accounting	Policies	–	Environmental	Matters"	in Management's	Discussion	and	Analysis	of	Financial	Condition	and	Results	of	Operations	and	"Note	14	–	Legal	Proceedings,	Commitments	and	Contingencies"	of	our consolidated	financial	statements.

On	October	26,	2015,	 the	New	Mexico	Environmental	Department	(NMED)	 issued	 a	 Notice	 of	Violation	 (NOV)	 related	 to	 a	 hazardous	 waste	 compliance evaluation	 that	 NMED	 conducted	 at	 Sandia	 National	 Laboratories	 in	 April	 2015.	 Sandia	 Corporation	 manages	 Sandia	 National	 Laboratories	 on	 behalf	 of	 the Department	of	Energy.	The	NOV	sets	forth	several	violations	of	New	Mexico's	Hazardous	Waste	Regulations	generally	related	to	alleged	failures	to:	make	hazardous waste	 determinations,	 determine	 if	 waste	 meets	 land	 disposal	 standards,	 prepare	 proper	 manifests,	 properly	 train	 personnel,	 complete	 inspection	 forms,	 maintain inspection	records,	properly	label	waste	and	comply	with	time-based	waste	storage	limits.	Unlawful	disposal	of	waste	as	a	result	of	the	foregoing	was	also	alleged. NMED	proposed	a	civil	penalty	of	approximately	$151,000	which	Sandia	Corporation	paid.	We	do	not	currently	believe	that	it	is	probable	that	we	will	incur	a	material loss	related	to	this	matter.

We	have	reached	an	agreement	to	settle	with	the	U.S.	Department	of	Justice	(DOJ)	and	the	qui	tam	relators	two	previously	disclosed	lawsuits	in	which	the	DOJ filed	 complaints	 in	 partial	 intervention	 on	August	 28,	 2003.	The	 lawsuits,	 United	 States	 ex	 rel.	 Natural	 Resources	 Defense	 Council,	 et	 al.,	 v.	 Lockheed	 Martin Corporation,	et	al.,	and	United	States	ex	rel.	John	D.	Tillson	v.	Lockheed	Martin	Energy	Systems,	Inc.,	et	al.,	were	filed	by	the	relators	in	1999	under	the	civil	qui	tam provisions	 of	 the	 False	 Claims	Act	 in	 the	 U.S.	 District	 Court	 for	 the	Western	 District	 of	 Kentucky	 and	 alleged	 that	 we	 committed	 violations	 of	 the	 Resource Conservation	and	Recovery	Act	(RCRA)	at	the	Paducah	Gaseous	Diffusion	Plant	by	not	properly	handling,	storing	and	transporting	hazardous	waste	and	that	we violated	the	False	Claims	Act	by	misleading	Department	of	Energy	officials	and	state	regulators	about	the	nature	and	extent	of	environmental	noncompliance	at	the plant.	The	parties	are	finalizing	the	terms	of	the	settlement	agreement,	which	is	considered	a	tentative	agreement	until	it	is	formally	approved	by	the	United	States Government.	Under	the	terms	of	our	agreement,	we	will	pay	$5	million,	of	which	$4	million	will	be	allocated	to	all	Defendants,	including	the	Corporation	and	its predecessor,	Martin	Marietta	Corporation;	wholly-owned	subsidiary	Lockheed	Martin	Energy	Systems,	Inc.	and	its	predecessor,	Martin	Marietta	Energy	Systems,	Inc.; and	wholly-owned	subsidiary	Lockheed	Martin	Utility	Services,	Inc.	and	its	predecessor	Martin	Marietta	Utility	Services,	Inc.	and	the	False	Claims	Act	allegations; $500,000	will	be	allocated	to	Lockheed	Martin	Energy	Systems,	Inc.	and	RCRA	civil	penalties;	and	$500,000	will	be	allocated	to	Lockheed	Martin	Utility	Services,	Inc. and	RCRA	civil	penalties.	We	believe	that	we	have	substantial	defenses	to	all	of	the	allegations	and	have	agreed	to	settle	the	case	to	avoid	the	costs	of	further	litigation of	this	matter	which	has	been	ongoing	in	excess	of	sixteen	years.	We	will	admit	no	liability	or	wrongdoing	in	resolving	the	matter.

As	a	U.S.	Government	contractor,	we	are	subject	to	various	audits	and	investigations	by	the	U.S.	Government	to	determine	whether	our	operations	are	being conducted	in	accordance	with	applicable	regulatory	requirements.	U.S.	Government	investigations	of	us,	whether	relating	to	government	contracts	or	conducted	for	other reasons,	could	result	in	administrative,	civil,	or	criminal	liabilities,	including	repayments,	fines	or	penalties	being	imposed	upon	us,	suspension,	proposed	debarment, debarment	from	eligibility	for	future	U.S.	Government	contracting,	or	suspension	of	export	privileges.	Suspension	or	debarment	could	have	a	material	adverse	effect	on us	because	of	our	dependence	on	contracts	with	the	U.S.	Government.	U.S.	Government	investigations	often	take	years	to	complete	and	many	result	in	no	adverse	action against	us.	We	also	provide	products	and	services	to	customers	outside	of	the	U.S.,	which	are	subject	to	U.S.	and	foreign	laws	and	regulations	and	foreign	procurement policies	and	practices.	Our	compliance	with	local	regulations	or	applicable	U.S.	Government	regulations	also	may	be	audited	or	investigated.

(a) We	close	our	books	and	records	on	the	last	Sunday	of	each	month	to	align	our	financial	closing	with	our	business	processes,	except	for	the	month	of	December,	as	our	fiscal year	ends	on	December	31.	As	a	result,	our	fiscal	months	often	differ	from	the	calendar	months.	For	example,	September	28,	2015	was	the	first	day	of	our	October	2015 fiscal	month.

(b) In	October	2010,	our	Board	of	Directors	approved	a	share	repurchase	program	pursuant	to	which	we	are	authorized	to	repurchase	our	common	stock	in	privately	negotiated transactions	or	in	the	open	market	at	prices	per	share	not	exceeding	the	then-current	market	prices.	On	September	24,	2015,	our	Board	of	Directors	authorized	a	$3.0	billion increase	to	the	program.	Under	the	program,	management	has	discretion	to	determine	the	dollar	amount	of	shares	to	be	repurchased	and	the	timing	of	any	repurchases	in compliance	with	applicable	law	and	regulation.	This	includes	purchases	pursuant	to	Rule	10b5-1	plans.	The	program	does	not	have	an	expiration	date.

(c) During	the	quarter	ended	December	31,	2015,	the	total	number	of	shares	purchased	included	10,090	shares	that	were	transferred	to	us	by	employees	in	satisfaction	of minimum	tax	withholding	obligations	associated	with	the	vesting	of	restricted	stock	units.	These	purchases	were	made	pursuant	to	a	separate	authorization	by	our	Board	of Directors	and	are	not	included	within	the	program.

(b) The	impact	of	our	postretirement	benefit	plans	can	cause	our	operating	profit,	net	earnings,	cash	flows	and	amounts	recorded	on	our	Balance	Sheets	to	fluctuate.	Accordingly, our	earnings	were	affected	by	FAS/CAS	pension	income	of	$471	million	and	$376	million	in	2015	and	2014	and	expense	of	$482	million,	$830	million,	and	$922	million	in 2013,	2012,	and	2011.	We	had	$5	million	in	pension	contributions	in	2015	(for	Sikorsky	plans),	as	compared	to	$2.0	billion	in	2014,	$2.25	billion	in	2013,	$3.6	billion	in	2012 and	$2.3	billion	in	2011,	and	these	contributions	caused	fluctuations	in	our	operating	cash	flows	and	cash	balance	between	each	of	those	years.	Fluctuations	in	our	total	assets, total	liabilities	and	stockholders'	equity	between	years	from	2011	to	2014	primarily	were	due	to	the	annual	measurement	of	the	funded	status	of	our	postretirement	benefit plans.	See	"Critical	Accounting	Policies	–	Postretirement	Benefit	Plans"	in	Management's	Discussion	and	Analysis	of	Financial	Condition	and	Results	of	Operations	for	more information.

(c) Certain	prior	period	amounts	have	been	reclassified	to	conform	to	current	year	presentation.

(d) The	increase	in	our	goodwill	and	total	assets	from	2014	to	2015	was	primarily	attributable	to	the	Sikorsky	acquisition,	which	resulted	in	an	increase	in	goodwill	and	total assets	of	$2.8	billion	and	$11.7	billion,	respectively.

(e) The	increase	in	our	total	debt	and	total	liabilities	from	2014	to	2015	was	primarily	a	result	of	the	debt	incurred	to	fund	the	Sikorsky	acquisition,	as	well	as	the	issuance	of debt	in	February	of	2015	for	general	corporate	purposes	(Note	3	and	Note	10).

(f) The	fluctuations	in	our	net	cash	provided	by	operating	activities	between	years	from	2011	to	2015	were	due	to	changes	in	pension	contributions,	working	capital	and	tax payments	made.	See	"Liquidity	and	Cash	Flows"	in	Management's	Discussion	and	Analysis	of	Financial	Condition	and	Results	of	Operations	for	more	information.

(g) The	increase	in	our	cash	used	for	investing	activities	in	2015	and	2014	was	attributable	to	acquisitions	of	businesses,	including	the	$9.0	billion	acquisition	of	Sikorsky	in 2015,	net	of	cash	acquired	(Note	3).

(h) The	increase	in	our	cash	provided	by	financing	activities	in	2015	was	primarily	a	result	of	the	debt	incurred	to	fund	the	Sikorsky	acquisition	(Note	10).	The	increase	in	our cash	used	for	financing	activities	in	2014	was	due	to	decreased	proceeds	from	stock	option	exercises,	higher	dividends	paid	and	increased	payments	for	repurchases	of common	stock.	See	"Liquidity	and	Cash	Flows"	in	Management's	Discussion	and	Analysis	of	Financial	Condition	and	Results	of	Operations	for	more	information.

(i) Backlog	at	December	31,	2015	includes	approximately	$15.6	billion	related	to	Sikorsky	and	$4.8	billion	related	to	our	IS&GS	business	segment,	which	we	plan	to	divest	in 2016.	Sikorsky	backlog	may	change	as	we	complete	our	acquired	backlog	analysis.

# ITEM	7. Management's	Discussion	and	Analysis	of	Financial	Condition	and	Results	of	Operations.

# Business	Overview

We	operate	in	five	business	segments:	Aeronautics,	Information	Systems	&	Global	Solutions	(IS&GS),	Missiles	and	Fire	Control	(MFC),	Mission	Systems	and Training	(MST)	and	Space	Systems.	We	organize	our	business	segments	based	on	the	nature	of	products	and	services	offered.

We	operate	in	an	environment	characterized	by	both	increasing	complexity	in	global	security	and	continuing	economic	pressures	in	the	U.S.	and	globally.	A significant	component	of	our	strategy	in	this	environment	is	to	focus	on	program	execution,	improving	the	quality	and	predictability	of	the	delivery	of	our	products	and services	and	placing	security	capability	quickly	into	the	hands	of	our	U.S.	and	international	customers	at	affordable	prices.	Recognizing	that	our	customers	are	resource constrained,	we	are	endeavoring	to	develop	and	extend	our	portfolio	domestically	in	a	disciplined	manner	with	a	focus	on	adjacent	markets	close	to	our	core	capabilities, as	well	as	growing	our	international	sales.	We	continue	to	focus	on	affordability	initiatives.	We	also	expect	to	continue	to	invest	in	technologies	to	fulfill	new	mission requirements	for	our	customers	and	invest	in	our	people	so	that	we	have	the	technical	skills	necessary	to	succeed	without	limiting	our	ability	to	return	substantially	all	of our	free	cash	flow1	to	our	investors	in	the	form	of	dividends	and	share	repurchases	over	the	next	two	years.

We	expect	2016	net	sales	will	increase	in	the	high	single	digit	range	from	2015	levels.	The	projected	growth	is	driven	by	the	addition	of	Sikorsky	and	increased volume	expected	on	the	F-35	program,	offset	by	volume	declines	at	our	IS&GS	and	Space	Systems	business	segments.	We	expect	our	2016	segment	operating	profit will	decline	in	the	high	single	digit	range	from	2015	levels	due	to	an	expected	decrease	in	segment	operating	profit	at	our	IS&GS,	MFC	and	Space	Systems	business segments.	Operating	margin	is	expected	to	decline	due	to	costs	associated	with	the	Sikorsky	acquisition,	including	the	impact	of	purchase	accounting	adjustments, integration	costs	and	inherited	restructuring	costs	associated	with	actions	committed	to	by	Sikorsky	prior	to	acquisition.	Accordingly,	we	expect	2016	segment	operating profit	margin	will	be	below	2015	levels,	in	the	10%	range.	Our	2016	outlook	includes	amounts	for	the	government	IT	infrastructure	services	and	technical	services businesses	we	expect	to	divest.	The	2016	outlook	will	not	be	adjusted	to	exclude	these	businesses	until	a	divestiture	is	completed.	Our	outlook	for	2016	assumes	the	U.S. Government	continues	to	support	and	fund	our	key	programs,	consistent	with	the	government	fiscal	year	(GFY)	2016	budget.	Changes	in	circumstances	may	require	us to	revise	our	assumptions,	which	could	materially	change	our	current	estimate	of	2016	net	sales	and	operating	profit	margin.	For	additional	information	related	to	trends in	net	sales	and	operating	profit	at	our	business	segments,	see	the	"Business	Segment	Results	of	Operations"	section	below.

# Portfolio	Shaping	Activities

We	continuously	strive	to	strengthen	our	portfolio	of	products	and	services	to	meet	the	current	and	future	needs	of	our	customers.	We	accomplish	this	in	part	by	our independent	research	and	development	activities	and	through	acquisition,	divestiture	and	internal	realignment	activities.

We	selectively	pursue	the	acquisition	of	businesses	and	investments	at	attractive	valuations	that	will	expand	or	complement	our	current	portfolio	and	allow	access to	new	customers	or	technologies.	We	also	may	explore	the	divestiture	of	businesses	that	no	longer	meet	our	needs	or	strategy	or	that	could	perform	better	outside	of	our organization.	In	pursuing	our	business	strategy,	we	routinely	conduct	discussions,	evaluate	targets	and	enter	into	agreements	regarding	possible	acquisitions,	divestitures, ventures	and	equity	investments.

1	We	define	free	cash	flow	as	cash	from	operations	as	determined	under	U.S.	generally	accepted	accounting	principles	(GAAP),	less	capital	expenditures	as	presented	on	our Statements	of	Cash	Flows.

On	November	6,	2015,	pursuant	to	a	Stock	Purchase	Agreement,	dated	as	of	July	19,	2015	by	and	between	us	and	United	Technologies	Corporation	(UTC)	and certain	wholly-owned	subsidiaries	of	UTC,	we	completed	the	acquisition	of	Sikorsky	Aircraft	Corporation	(Sikorsky)	for	$9.0	billion,	net	of	cash	acquired.	Sikorsky,	a global	company	primarily	engaged	in	the	design,	manufacture,	service	and	support	of	military	and	commercial	helicopters,	has	become	a	wholly-owned	subsidiary	of ours,	aligned	under	the	MST	business	segment.	We	funded	the	acquisition	with	new	debt	issuances,	commercial	paper	and	cash	on	hand.	We	and	UTC	made	a	joint election	under	Section	338(h)(10)	of	the	Internal	Revenue	Code,	which	treats	the	transaction	as	an	asset	purchase	for	tax	purposes.	This	election	generates	a	cash	tax benefit	with	an	estimated	net	present	value	of	$1.9	billion	for	us	and	our	stockholders.	The	financial	results	of	the	acquired	Sikorsky	business	have	been	included	in	our consolidated	results	of	operations	from	the	November	6,	2015	acquisition	date	through	December	31,	2015.	Accordingly,	the	consolidated	financial	results	for	the	year ended	December	31,	2015	do	not	reflect	a	full	year	of	Sikorsky	operations.	See	"Capital	Structure,	Resources	and	Other"	below	for	a	discussion	of	the	debt	we	incurred in	connection	with	the	Sikorsky	acquisition.

On	January	26,	2016	we	entered	into	definitive	agreements	to	separate	and	combine	our	Information	Systems	&	Global	Solutions	(IS&GS)	business	segment	with Leidos	Holdings,	Inc.	(Leidos)	in	a	tax-efficient	Reverse	Morris	Trust	transaction	anticipated	to	unlock	approximately	$5.0	billion	in	estimated	enterprise	value	for	our stockholders,	including	a	$1.8	billion	one-time	special	cash	payment	to	us.	We	intend	to	use	the	net	proceeds	of	the	transaction	to	repay	debt,	pay	dividends	or repurchase	our	stock.	Additionally,	our	stockholders	will	receive	approximately	50.5	percent	of	the	outstanding	equity	of	Leidos	on	a	fully	diluted	basis	(approximately 77	million	shares)	with	an	estimated	value	of	$3.2	billion	based	on	Leidos'	stock	price	on	the	date	of	announcement.	However,	the	actual	value	of	the	stock	to	be received	by	our	stockholders	will	depend	on	the	value	of	such	shares	at	the	time	of	closing	of	the	transaction	and	our	stockholders	may	receive	more	or	less	than	the anticipated	value.	At	our	election,	the	distribution	may	be	effected	by	means	of	a	pro	rata	dividend	in	a	spin-off	transaction	or	in	an	exchange	offer	for	outstanding Lockheed	Martin	Shares	in	a	split-off	transaction.	The	transaction	structure,	which	is	subject	to	market	conditions,	is	currently	contemplated	to	be	a	split-off	transaction resulting	in	a	decrease	in	our	outstanding	common	shares	and	a	significant	book	gain	at	closing.	In	a	split-off	transaction,	only	those	stockholders	that	elect	to	participate will	receive	Leidos	shares	in	the	merger	transaction,	provided,	that,	if	the	exchange	offer	is	not	fully	subscribed,	Lockheed	Martin	will	spin-off	the	remaining	shares	to be	converted	into	Leidos	stock	in	the	merger	pro	rata.

Subsequent	to	the	program	realignment,	the	government	IT	and	technical	services	businesses	that	were	under	strategic	review	are	now	aligned	under	the	IS&GS business	segment.	The	program	realignment	did	not	impact	our	consolidated	results	of	operations.	The	amounts,	discussion	and	presentation	of	our	business	segment financial	results	for	all	periods	presented	reflect	this	realignment.

# Other	Acquisitions

In	addition	to	the	previously	described	acquisition	of	Sikorsky	in	2015,	we	had	the	following	significant	acquisition	related	activity	in	each	of	the	prior	two	years:

In	2014,	we	paid	$898	million	for	acquisitions	of	businesses	and	investments	in	affiliates,	net	of	cash	acquired,	primarily	related	to	the	following	acquisitions:

•Systems	Made	Simple	–	a	provider	of	health	information	technology	solutions,	which	is	included	in	our	IS&GS	business	segment;

•	 Zeta	Associates,	 Inc.	 –	 a	 designer	 of	 systems	 that	 enable	 collection,	 processing,	 safeguarding	 and	 dissemination	 of	 information for intelligence	 and	 defense communities,	which	is	included	in	our	Space	Systems	business	segment;	and

•Industrial	Defender	–	a	provider	of	cybersecurity	solutions	for	control	systems	in	the	oil	and	gas,	utility	and	chemical	industries,	which	is	included	in	our	IS&GS business	segment.

In	2013,	we	paid	$269	million	for	acquisitions	of	businesses	and	investments	in	affiliates,	net	of	cash	acquired,	primarily	related	to	the	acquisition	of	Amor	Group, a	United	Kingdom-based	company	specializing	in	information	technology,	civil	government	services	and	the	energy	market.	Amor	Group	is	included	in	our	IS&GS business	segment.

For	additional	information,	see	"Note	3	–	Acquisitions	and	Divestitures"	of	our	consolidated	financial	statements.

# Industry	Considerations

# U.S.	Government	Funding	Constraints

The	U.S.	Government,	our	principal	customer,	continues	to	face	significant	fiscal	and	economic	challenges	such	as	financial	deficits,	budget	uncertainty,	increasing debt	levels,	and	an	economy	with	restrained	growth.	To	address	these	challenges,	the	U.S.	Government	continues	to	focus	on	discretionary	spending,	entitlement programs,	taxes,	and	other	initiatives	to	stimulate	the	economy,	create	jobs,	and	reduce	the	deficit.	In	doing	so,	the	Administration	and	Congress	must	balance	decisions regarding	defense,	homeland	security	and	other	federal	spending	priorities	in	a	constrained	fiscal	environment	largely	imposed	by	the	Budget	Control	Act	of	2011 (Budget	Control	Act).	The	Budget	Control	Act	established	limits	on	discretionary	spending,	which	provided	for	reductions	to	planned	defense	spending	of	$487	billion over	a	10	year	period	that	began	with	GFY	2012	(a	U.S.	Government	fiscal	year	starts	on	October	1	and	ends	on	September	30).	The	Budget	Control	Act	also	provided for	additional	automatic	spending	reductions,	known	as	sequestration,	which	went	into	effect	on	March	1,	2013,	that	would	have	reduced	planned	defense	spending	by an	additional	$500	billion	over	a	nine-year	period	that	began	in	GFY	2013.

On	November	2,	2015,	the	President	signed	into	law	the	Bipartisan	Budget	Act	of	2015	(BBA	2015).	BBA	2015	raises	the	limit	on	the	government's	debt	until March	2017	and	raises	the	sequester	caps	imposed	by	the	Budget	Control	Act	by	$80	billion,	split	equally	between	defense	and	non-defense	spending	over	the	next	two years	($50	billion	in	GFY	2016	and	$30	billion	in	GFY	2017).	On	December	18,	2015,	the	President	signed	into	law	the	Consolidated	Appropriations	Act	of	2016, funding	the	government	through	September	30,	2016	and	on	February	9,	2016,	the	President	submitted	a	budget	proposal	for	GFY	2017,	consistent	with	BBA	2015 funding	levels.	BBA	2015	includes	discretionary	funding	for	DoD	of	approximately	$580	billion	in	GFY	2016	and	$583	billion	in	GFY	2017.	This	funding	includes	a base	budget	for	the	DoD	of	approximately	$521	billion	in	GFY	2016	and	$524	billion	in	GFY	2017.	BBA	2015	also	provides	approximately	$59	billion	for	DoD Overseas	Contingency	Operations	(OCO)	spending	in	each	of	GFY	2016	and	GFY	2017.

The	Bipartisan	Budget	Act	of	2013	(BBA	2013)	passed	by	Congress	in	December	2013	alleviated	some	budget	cuts	that	would	have	otherwise	been	instituted through	sequestration	in	GFY	2014	and	GFY	2015.	Together,	BBA	2013	and	BBA	2015	(collectively,	the	Bipartisan	Budget	Acts)	increased	discretionary	spending limits	through	GFY	2017.	However,	the	Bipartisan	Budget	Acts	retained	sequestration	cuts	for	GFYs	2018	through	2021,	including	the	across-the-board	spending reduction	methodology	provided	for	in	the	Budget	Control	Act.	As	a	result,	there	remains	uncertainty	regarding	how,	or	if,	sequestration	cuts	will	be	applied	in	GFY 2018	and	beyond.	DoD	and	other	agencies	may	have	significantly	less	flexibility	in	how	to	apply	budget	cuts	in	future	years.	While	the	defense	budget	sustained	the largest	single	reductions	under	the	Budget	Control	Act,	other	civil	agencies	and	programs	have	also	been	impacted	by	significant	spending	reductions.	In	light	of	the Budget	Control	Act	and	deficit	reduction	pressures,	it	is	likely	that	discretionary	spending	by	the	U.S.	Government	will	remain	constrained	for	a	number	of	years. Additionally,	if	an	annual	appropriations	bill	is	not	enacted	for	GFY	2017	or	beyond,	the	U.S.	Government	may	operate	under	a	continuing	resolution,	restricting	new contract	or	program	starts	and

government	shutdowns	could	arise.	We	anticipate	there	will	continue	to	be	significant	debate	within	the	U.S.	Government	over	defense	spending	throughout	the	budget appropriations	process	for	GFY	2017	and	beyond.	The	outcome	of	these	debates	could	have	long-term	consequences	for	our	industry	and	company	as	described	below. However,	we	continue	to	believe	that	our	portfolio	of	products	and	services	will	continue	to	be	well	supported	in	a	strategically	focused	allocation	of	budget	resources.

# Potential	Impacts	of	Budget	Reductions

While	recent	budget	actions	provide	a	more	measured	and	strategic	approach	to	addressing	the	U.S.	Government's	fiscal	challenges,	sequestration	remains	a	long- term	concern.	If	not	further	modified,	sequestration	could	have	significant	negative	impacts	on	our	industry	and	company	in	future	periods.	There	may	be	disruption	of ongoing	programs,	impacts	to	our	supply	chain,	contractual	actions	(including	partial	or	complete	terminations),	potential	facilities	closures,	and	thousands	of	personnel reductions	across	the	industry	that	will	severely	impact	advanced	manufacturing	operations	and	engineering	expertise,	and	accelerate	the	loss	of	skills	and	knowledge. Sequestration,	or	other	budgetary	cuts	in	lieu	of	sequestration,	could	have	a	material	negative	effect	on	our	company.

Despite	the	continued	uncertainty	surrounding	U.S.	Government	budgets,	we	have	sought	to	align	our	businesses	with	what	we	believe	are	the	most	critical	national priorities	and	mission	areas.	Additionally,	we	are	seeking	to	lessen	our	dependence	on	contracts	with	the	U.S.	Government	by	focusing	on	expanding	into	adjacent markets	close	to	our	core	capabilities	and	growing	international	sales	but	we	may	not	be	successful	in	this	strategy.	The	possibility	remains,	however,	that	our	programs could	be	materially	reduced,	extended,	or	terminated	as	a	result	of	the	U.S.	Government's	continuing	assessment	of	priorities,	changes	in	government	priorities,	or budget	 reductions,	 including	 sequestration	 (particularly	 in	 those	 circumstances	 where	 sequestration	 is	 implemented	 across-the-board	 without	 regard	 to	 national priorities).	Additionally,	 decreases	 in	 production	 volume	 associated	 with	 budget	 cuts,	 including	 sequestration,	 will	 increase	 unit	 costs	 making	 our	 products	 less affordable	for	both	our	U.S.	and	international	customers.	In	particular,	if	sequestration	level	spending	cuts	are	reinstated	in	GFY	2018,	we	may	experience	significant rescheduling	or	termination	activity	with	our	supplier	base.	Such	activity	could	result	in	claims	from	our	suppliers,	which	may	include	the	amount	established	in	any settlement	agreements,	the	costs	of	evaluating	the	supplier	settlement	proposals,	and	the	costs	of	negotiating	settlement	agreements.	Budget	cuts,	including	sequestration, could	result	 in	restructuring	charges,	 impairment	of	assets,	 including	goodwill,	or	other	charges.	We	expect	costs	associated	with	claims	from	our	suppliers	and restructuring	charges	will	be	recovered	from	our	customers.

Generally,	we	expect	that	the	impact	of	budget	reductions	on	our	operating	results	will	lag	in	certain	of	our	businesses	with	longer	cycles	such	as	our	Aeronautics and	Space	Systems	business	segments,	and	our	products	businesses	within	our	MFC	and	MST	business	segments,	due	to	our	production	contract	backlog.	However,	our businesses	with	smaller,	short-term	contracts	are	 the	most	susceptible	 to	 the	 impacts	of	budget	reductions,	such	as	our	IS&GS	business	segment.	We	have	also experienced	increased	market	pressures	in	these	services	businesses	including	lower	in-theater	support	as	troop	levels	are	drawn	down	and	increased	re-competition	on existing	contracts	coupled	with	the	fragmentation	of	large	contracts	into	multiple	smaller	contracts	that	are	awarded	primarily	on	the	basis	of	price.	Additionally,	our services	businesses	across	most	of	our	business	segments	have	experienced	lower	volume	due	to	improved	product	field	performance	that	require	less	service	support.

# International	Business

A	key	component	of	our	strategic	plan	is	to	grow	our	international	sales.	To	accomplish	this	growth,	we	continue	to	focus	on	expanding	our	in-country	presence and	strengthening	our	relationships	internationally	through	partnerships	and	local	production	joint	technology	offices.	Since	2013,	we	have	acquired	Amor	Group,	a United	Kingdom-based	company,	and	we	have	opened	new	in-country	offices	including	in	Israel,	United	Kingdom,	the	United	Arab	Emirates	(UAE),	Saudi	Arabia	and Qatar	that	will	enable	development	of	ventures	to	create	products	and	enhance	our	offerings	in	technology,	aerospace	and	security	sectors.	We	conduct	business	with international	customers	primarily	through	our	Aeronautics,	MFC	and	MST	business	segments.

In	 our	Aeronautics	 business	 segment,	 there	 remains	 strong	 international	 interest	 in	 the	 F-35	 program.	The	 F-35	 program	 includes	 commitments	 from	 eight international	partner	countries	and	three	international	customers;	as	well	as	expressions	of	interest	from	other	countries.	The	U.S.	Government	and	the	eight	partner countries	continue	to	work	together	on	the	design,	testing,	production	and	sustainment	of	the	F-35.	The	international	role	on	the	program	continues	to	grow	as	we	have successfully	delivered	aircraft	to	five	international	partners,	including	the	first	two	Norwegian	aircraft.	In	2015,	the	first	Italian	Final	Assembly	and	Check-Out	Facility produced	F-35	aircraft	was	delivered.	The	award	of	the	Low	Rate	Initial	Production	(LRIP)	9	undefinitized	contract	action	in	2015	included	21	international	orders	for four	international	partners	and	customers.

Other	areas	of	international	expansion	at	our	Aeronautics	business	segment	include	the	F-16	and	C-130J	programs.	In	2015,	the	Iraqi	F-16	contract	was	definitized and	production	continues	into	2017.	Also,	the	award	from	Singapore	in	2015	for	F-16	aircraft	upgrades	establishes	work	into	2023.	The	C-130J	Super	Hercules	aircraft continued	to	draw	interest	from	various	international	customers	in	2015.

Our	MFC	business	segment	produces	the	Patriot	Advanced	Capability-3	(PAC-3)	and	Terminal	High	Altitude	Area	Defense	(THAAD)	air	and	missile	defense systems,	which	continue	to	generate	significant	international	interest.	The	PAC-3	is	an	advanced	missile	defense	system	designed	to	intercept	incoming	airborne	threats. During	2015	we	received	orders	for	PAC-3	systems	from	the	Kingdom	of	Saudi	Arabia	and	South	Korea,	in	addition	to	the	award	we	received	in	2014	to	provide	PAC-3 missile	defense	equipment	to	Qatar.	THAAD	international	customers	include	the	UAE.	Other	international	customers	include	Japan,	Germany,	the	Netherlands,	Taiwan and	Kuwait.	Other	countries	in	the	Middle	East,	Europe	and	the	Asia-Pacific	region	have	also	expressed	interest	in	our	air	and	missile	defense	systems.	Additionally,	we continue	to	see	international	demand	for	our	tactical	missile	and	fire	control	products.

In	our	MST	business	segment,	we	continue	 to	experience	 international	 interest	 in	 the	Aegis	Ballistic	Missile	Defense	System.	We	perform	activities	 in	 the development,	production,	ship	integration	and	test	and	lifetime	support	for	ships	of	international	customers	such	as	Japan,	Spain,	Korea	and	Australia.	We	have	an ongoing	program	in	Canada	for	combat	systems	equipment	upgrades	on	13	Halifax-class	frigates.	In	our	training	and	logistics	solutions	portfolio,	we	have	active programs	and	pursuits	in	United	Kingdom,	Saudi	Arabia,	Canada,	Singapore,	Qatar,	and	Australia.

Our	acquisition	of	Sikorsky	adds	a	significant	international	component	to	the	MST	business	segment	with	an	installed	base	of	over	1,000	aircraft	internationally. We	have	active	development,	production,	and	sustainment	support	of	the	UH-60	Black	Hawk	and	MH-60	Seahawk	aircraft	to	foreign	military	customers,	including Australia,	Denmark,	Taiwan,	Saudi	Arabia,	and	Colombia.	The	S-76	and	S-92	aircraft	is	sold	to	commercial	customers	in	the	oil	and	gas	industry,	emergency	medical evacuation,	and	search	and	rescue	fleets	in	over	30	countries,	including	customers	and	end-users	in	China,	Japan,	Brazil,	Saudi	Arabia,	the	UAE,	and	the	United Kingdom.

# Status	of	the	F-35	Program

The	F-35	program	consists	of	a	development	contracts,	multiple	production	contracts	and	sustainment	activities.	The	development	contracts	are	being	performed concurrent	with	the	production	contracts.	Concurrent	performance	of	development	and	production	contracts	is	used	for	complex	programs	to	test	aircraft,	shorten	the time	to	field	systems,	and	achieve	overall	cost	savings.	We	expect	the	System	Development	and	Demonstration	portion	of	the	development	contracts	will	be	substantially complete	in	2017,	with	less	significant	efforts	continuing	into	2019.	Production	of	the	aircraft	is	expected	to	continue	for	many	years	given	the	U.S.	Government's current	inventory	objective	of	2,443	aircraft	for	the	Air	Force,	Marine	Corps,	and	Navy;	commitments	from	our	eight	international	partners	and	three	international customers;	as	well	as	expressions	of	interest	from	other	countries.

The	U.S.	Government	continues	to	complete	various	operational	tests,	including	ship	trials,	mission	system	evaluations,	and	weapons	testing,	with	the	F-35	aircraft fleet	recently	surpassing	50,000	flight	hours.	Progress	continues	to	be	made	on	the	production	of	aircraft.	In	July	2015,	the	U.S.	Marine	Corps	declared	that	the	F-35B had	reached	initial	operating	capability,	which	makes	it	the	first	variant	available	for	combat.	As	of	December	31,	2015,	we	have	delivered	154	production	aircraft	to	our U.S.	and	international	partners	including	delivery	of	the	first	Italian	Final	Assembly	and	Check-Out	Facility	produced	F-35,	and	have	114	production	aircraft	in	backlog, including	orders	from	our	international	partners.

Given	the	size	and	complexity	of	the	F-35	program,	we	anticipate	that	there	will	be	continual	reviews	related	to	aircraft	performance,	program	schedule,	cost,	and requirements	as	part	of	the	DoD,	Congressional,	and	international	partners'	oversight	and	budgeting	processes.	Current	program	challenges	include,	but	are	not	limited to,	supplier	and	partner	performance,	software	development,	level	of	cost	associated	with	life	cycle	operations	and	sustainment	and	warranties,	receiving	funding	for production	contracts	on	a	timely	basis,	executing	future	flight	tests,	findings	resulting	from	testing,	and	operating	the	aircraft.

# Cybersecurity

On	July	9,	2015,	the	U.S.	Office	of	Personnel	Management	(OPM)	announced	that	the	background	investigation	records	of	21.5	million	current,	former	and prospective	Federal	employees	and	contractors	had	been	compromised	as	a	result	of	a	cyber-security	incident.	Many	of	our	current	as	well	as	former	employees	were	the subjects	of	background	investigations	in

connection	with	former	government	service	or	as	part	of	the	screening	process	for	a	security	clearance.	We	are	currently	assessing	the	impact	of	this	cyber-security incident	but	do	not	yet	know	the	impact,	if	any,	on	Lockheed	Martin	or	our	current	or	former	employees.

# Consolidated	Results	of	Operations

Since	our	operating	cycle	is	primarily	long	term	and	involves	many	types	of	contracts	for	the	design,	development	and	manufacture	of	products	and	related activities	with	varying	delivery	schedules,	the	results	of	operations	of	a	particular	year,	or	year-to-year	comparisons	of	sales	and	profits,	may	not	be	indicative	of	future operating	results.	The	following	discussions	of	comparative	results	among	years	should	be	reviewed	in	this	context.	All	per	share	amounts	cited	in	these	discussions	are presented	on	a	"per	diluted	share"	basis,	unless	otherwise	noted.	Our	consolidated	results	of	operations	were	as	follows	(in	millions,	except	per	share	data):

(a) Operating	profit	includes	$45	million	of	operating	loss	at	Sikorsky,	which	is	less	than	one	percent	of	consolidated	operating	profit	in	2015.	Sikorsky's	operating	loss	is	net	of intangible	amortization	and	adjustments	required	to	account	for	the	acquisition	of	this	business	in	the	fourth	quarter	of	2015.

Certain	amounts	reported	in	other	income,	net,	primarily	our	share	of	earnings	or	losses	from	equity	method	investees,	are	included	in	the	operating	profit	of	our business	segments.	Accordingly,	such	amounts	are	included	in	our	discussion	of	our	business	segment	results	of	operations.

# Net	Sales

We	generate	sales	from	the	delivery	of	products	and	services	to	our	customers.	Product	sales	are	predominantly	generated	in	our	Aeronautics,	MFC,	MST	and Space	Systems	business	segments	and	most	of	our	service	sales	are	generated	in	our	IS&GS	and	MST	business	segments.	Our	consolidated	net	sales	were	as	follows	(in millions):

|  | 2015 | 2014 | 2013 |
| :--- | :--- | :--- | :--- |
| Products | $35,882 | $36,093 | $35,691 |
| Services | \t 10,250 | 9,507 | 9,667 |
| Total\tnet\tsales | $46,132 | $45,600 | $45,358 |

Substantially	all	of	our	contracts	are	accounted	for	using	the	percentage-of-completion	method.	Under	the	percentage-of-completion	method,	we	record	net	sales	on contracts	based	upon	our	progress	towards	completion	on	a	particular	contract,	as	well	as	our	estimate	of	the	profit	to	be	earned	at	completion.	The	following	discussion of	material	changes	in	our	consolidated	net	sales	should	be	read	in	tandem	with	the	subsequent	discussion	of	changes	in	our	consolidated	cost	of	sales	and	our	business segment	results	of	operations	because	changes	in	our	sales	are	typically	accompanied	by	a	corresponding	change	in	our	cost	of	sales	due	to	the	nature	of	the	percentage- of-completion	method.

# Product	Sales

Our	product	sales	represent	78%	of	our	total	sales	in	2015	and	79%	of	our	total	sales	in	2014.	Product	sales	decreased	$211	million,	or	1%,	in	2015	as	compared	to 2014.	Lower	product	sales	of	about	$290	million	at	Space	Systems,	approximately	$250	million	at	MFC	and	approximately	$110	million	at	IS&GS	were	offset	by	higher product	sales	of	about	$320	million	at	MST	and	approximately	$120	million	at	Aeronautics.	The	decrease	in	product	sales	at	Space	Systems	was	attributable	to	lower volume	for	government	satellite	programs	(primarily	Advanced	Extremely	High	Frequency	(AEHF).	Product	sales	at	MFC	decreased	due	to	lower	volume	on	air	and missile	defense	systems	programs	(primarily	PAC-3).	The	decline	in	product	sales	at	IS&GS	was	a	result	of	key	program	completions,	lower	customer	funding	levels and	increased	competition,	coupled	with	the	fragmentation	of	existing	large	contracts	into	multiple	smaller	contracts	that	are	awarded	primarily	on	the	basis	of	price.	The increase	in	product	sales	at	MST	was	primarily	attributable	to	product	sales	from	Sikorsky,	which	we	acquired	in	the	fourth	quarter	of	2015.	Product	sales	at	Aeronautics increased	primarily	due	to	higher	volume	on	F-35	production	contracts,	as	well	as	increased	deliveries	on	our	C-5	program;	partially	offset	by	fewer	aircraft	deliveries for	our	C-130	and	F-16	programs	and	lower	sustainment	activities	on	our	F-22	program.

Our	product	sales	represent	79%	of	our	total	sales	in	both	2014	and	2013.	Product	sales	increased	$402	million,	or	1%,	in	2014	as	compared	to	2013.	Higher	product sales	of	about	$815	million	at	Aeronautics	and	approximately	$280	million	at	MFC	were	partially	offset	by	lower	product	sales	of	about	$275	million	at	Space	Systems, approximately	$235	million	at	IS&GS	and	approximately	$185	million	at	MST.	The	increase	in	product	sales	at	Aeronautics	was	attributable	to	higher	volume	on	F-35 production	contracts	and	sustainment	activities,	increased	aircraft	deliveries	(F-16	program)	and	increased	risk	retirements	(F-22	program).	Product	sales	at	MFC increased	as	a	result	of	increased	volume	on	air	and	missile	defense	systems	programs	(primarily	THAAD),	and	increased	deliveries	on	fire	control	programs	(including the	Apache	Fire	Control	System	(Apache)).	The	decline	in	product	sales	at	Space	Systems	was	due	to	lower	volume	for	government	satellite	programs	(primarily Advanced	Extremely	High	Frequency	(AEHF),	Global	Positioning	System	III	(GPS-III),	and	Mobile	User	Objective	System	(MUOS));	and	as	a	result	of	mission solutions'	programs	transitioning	from	development	to	operations	and	support,	wind-down	or	completion	of	certain	programs,	and	defense	budget	cuts.	The	decline	in product	sales	at	Space	Systems	was	partially	offset	by	increased	volume	in	the	Orion	program	(primarily	the	first	unmanned	test	flight	of	the	Orion	Multi-Purpose	Crew Vehicle	(MPCV)).	Lower	product	sales	at	IS&GS	were	primarily	due	to	the	wind	down	or	completion	of	certain	programs	and	decreased	volume	in	technical	services programs	 reflecting	 market	 pressures.	 Lower	 product	 sales	 at	 MST	 were	 primarily	 driven	 by	 the	 wind-down	 or	 completion	 of	 certain	 command,	 control, communications,	computers,	intelligence,	surveillance	and	reconnaissance	(C4ISR)	programs	(primarily	PTDS).

# Service	Sales

Our	service	sales	represent	22%	of	our	total	sales	in	2015	and	21%	of	our	total	sales	in	2014.	Service	sales	increased	$743	million,	or	8%,	in	2015	as	compared	to 2014.	The	increase	in	service	sales	was	primarily	attributable	to	higher	service	sales	of	approximately	$530	million	at	Aeronautics	and	about	$190	million	at	Space Systems.	Higher	service	sales	at	Aeronautics	were	primarily	due	to	increased	sustainment	activities	(primarily	F-35).	The	increase	in	service	sales	at	Space	Systems	was primarily	due	to	service	sales	of	entities	acquired	in	the	third	quarter	of	2014.

Our	service	sales	represent	21%	of	our	total	sales	in	both	2014	and	2013.	Service	sales	decreased	$160	million,	or	2%,	in	2014	as	compared	to	2013.	Lower	service sales	of	approximately	$225	million	at	IS&GS	and	approximately	$120	million	at	MST	were	partially	offset	by	higher	service	sales	at	Space	Systems	of	about	$190 million.	The	decline	in	service	sales	at	IS&GS	was	primarily	due	to	various	technical	services	programs	as	a	result	of	decreased	volume	reflecting	market	pressures.	The decline	in	service	sales	at	MST	was	primarily	due	to	the	wind-down	or	completion	of	certain	programs.	The	increase	in	sales	at	Space	Systems	was	primarily	due	to commercial	space	transportation	programs	resulting	from	launch-related	activities.

# Cost	of	Sales

Cost	 of	 sales,	 for	 both	 products	 and	 services,	 consist	 of	 materials,	 labor,	 subcontracting	 costs,	 an	 allocation	 of	 indirect	 costs	 (overhead	 and	 general	 and administrative),	as	well	as	the	costs	to	fulfill	our	industrial	cooperation	agreements,	sometimes	referred	to	as	offset	agreements,	required	under	certain	contracts	with international	customers.	For	each	of	our	contracts,	we	monitor	the	nature	and	amount	of	costs	at	the	contract	level,	which	form	the	basis	for	estimating	our	total	costs	to complete	the	contract.	Our	consolidated	cost	of	sales	were	as	follows	(in	millions):

|  | 2015 | 2014 | 2013 |
| :--- | :--- | :--- | :--- |
| Cost\tof\tsales\t–\tproducts | $(32,006) | $(31,965) | $(31,346) |
| %\tof\tproduct\tsales | 89.2% | 88.6% | 87.8% |
| Cost\tof\tsales\t–\tservices | (9,011) | (8,393) | (8,588) |
| %\tof\tservice\tsales | 87.9% | 88.3% | 88.8% |
| Goodwill\timpairment\tcharges | — | (119) | (195) |
| Severance\tcharges | (102) | — | (201) |
| Other\tunallocated,\tnet | 187 | 132 | (841) |
| Total\tcost\tof\tsales | $(40,932) | $(40,345) | $(41,171) |

Due	to	the	nature	of	percentage-of-completion	accounting,	changes	in	our	cost	of	sales	for	both	products	and	services	are	typically	accompanied	by	changes	in	our net	sales.	The	following	discussion	of	material	changes	in	our	consolidated	cost	of	sales	for	products	and	services	should	be	read	in	tandem	with	the	preceding	discussion of	changes	in	our	consolidated	net	sales	and	our	business	segment	results	of	operations.	We	have	not	identified	any	developing	trends	in	cost	of	sales	for	products	and services	that	would	have	a	material	impact	on	our	future	operations.

# Product	Costs

Product	costs	increased	approximately	$41	million,	or	less	than	1%,	in	2015	as	compared	to	2014.	Increased	product	costs	of	approximately	$445	million	at	MST and	about	$180	million	at	Aeronautics,	were	offset	by	decreases	in	product	costs	of	approximately	$325	million	at	Space	Systems,	$195	million	at	MFC	and	$65	million at	IS&GS.	Increases	 in	product	costs	at	MST	were	due	primarily	 to	 the	Sikorsky	acquisition,	 including	costs	of	Sikorsky	products,	 intangible	amortization	and adjustments	required	to	account	for	the	acquisition	in	the	fourth	quarter	of	2015.	Higher	product	costs	at	Aeronautics	were	attributable	to	the	reasons	stated	above	for higher	product	sales,	as	well	as	decreased	risk	retirements	(primarily	F-22).	The	changes	in	product	costs	at	Space	Systems,	MFC	and	IS&GS	were	attributable	to	the reasons	stated	above	for	higher	product	sales.

Product	costs	increased	$619	million,	or	2%,	in	2014	as	compared	to	2013.	Product	costs	increased	approximately	$815	million	at	Aeronautics	and	approximately $325	million	at	MFC.	Increases	in	product	costs	at	Aeronautics	and	MFC	were	primarily	due	to	the	reasons	described	above	for	higher	product	sales	at	each	respective business	segment	and	net	warranty	reserve	adjustments	recorded	in	2014	at	MFC	(including	Joint	Air-to-Surface	Standoff	Missile	(JASSM),	and	Guided	Multiple Launcher	Rocker	Systems	(GMLRS)).	These	increases	in	product	costs	were	partially	offset	by	decreases	of	about	$195	million	at	IS&GS,	$255	million	at	Space Systems	and	$70	million	at	MST,	primarily	due	to	the	reasons	described	above	for	lower	product	sales	at	each	respective	business	segment.	Additionally,	lower	product costs	at	MST	were	partially	offset	by	costs	related	to	the	settlements	of	contract	cost	matters	on	certain	programs	in	the	prior	year	(including	a	portion	of	the	terminated presidential	helicopter	program)	that	were	not	repeated	in	2014	and	higher	reserves	recorded	on	certain	training	and	logistics	solutions	programs	during	2014.	The	0.8% increase	in	product	costs	as	a	percentage	of	product	sales	in	2014	compared	to	2013	was	primarily	due	to	the	reasons	described	above	for	increasing	product	costs	at MFC,	and	decreased	risk	retirements	at	Aeronautics	(primarily	F-16).

# Service	Costs

Service	costs	increased	$618	million,	or	7%,	in	2015	compared	to	2014.	Higher	service	costs	of	approximately	$450	million	at	Aeronautics	and	about	$230	million at	Space	Systems	were	due	to	the	reasons	stated	above	for	higher	service	sales.	These	increases	in	service	costs	were	partially	offset	by	a	decrease	in	service	costs	of about	$80	million	at	MFC	due	primarily	to	lower	service	costs	on	various	air	and	missile	defense	programs.

Service	costs	decreased	$195	million,	or	2%,	in	2014	as	compared	to	2013.	Lower	service	costs	of	about	$230	million	at	IS&GS,	approximately	$100	million	at MST,	and	approximately	$40	million	at	Aeronautics	were	partially	offset	by	an	increase	in	service	costs	of	approximately	$160	million	at	Space	Systems.	The	decline	at IS&GS	was	primarily	attributable	to

lower	volume	for	various	technical	services	programs.	The	decline	at	MST	was	primarily	attributable	to	lower	costs	upon	wind-down	or	completion	of	certain	programs. The	decline	at	Aeronautics	was	mostly	attributable	to	decreased	sustainment	activities.	The	increase	at	Space	Systems	was	primarily	attributable	to	commercial	space transportation	programs	due	to	launch-related	activities.	The	0.5%	decrease	in	service	costs	as	a	percentage	of	service	sales	in	2014	compared	to	2013	was	primarily	due to	items	decreasing	service	costs	at	IS&GS.

# Goodwill	Impairment	Charges

In	the	fourth	quarter	of	2015,	we	performed	our	annual	goodwill	impairment	test	for	each	of	our	reporting	units.	Additionally,	as	part	of	our	previously	described program	realignment,	goodwill	was	re-allocated	between	affected	reporting	units	on	a	relative	fair	value	basis	and	goodwill	impairment	tests	were	performed	prior	and subsequent	to	the	realignment.	In	connection	with	our	goodwill	impairment	testing	in	2015,	we	determined	there	was	no	goodwill	impairment.

In	the	fourth	quarters	of	2014	and	2013,	we	recorded	non-cash	goodwill	impairment	charges	of	$119	million	and	$195	million,	which	reduced	our	net	earnings	by $107	million	($.33	per	share)	and	$176	million	($.54	per	share).	For	additional	information,	see	the	"Critical	Accounting	Policies	–	Goodwill"	section	below	and	"Note	1 –	Significant	Accounting	Policies"	of	our	consolidated	financial	statements.

# Restructuring	Charges

During	2015,	we	recorded	charges	related	to	certain	severance	actions	totaling	$102	million,	of	which	$67	million	related	to	our	MST	business	segment	and	$35 million	related	to	our	IS&GS	business	segment	(prior	to	realignment).	These	charges	reduced	our	2015	net	earnings	by	$66	million	($.21	per	share).	These	severance actions	resulted	from	a	review	of	future	workload	projections	and	to	reduce	our	costs	in	order	to	improve	the	affordability	of	our	products	and	services.	The	charges consisted	of	severance	costs	associated	with	the	planned	elimination	of	certain	positions	through	either	voluntary	or	involuntary	actions.	Upon	separation,	terminated employees	will	receive	lump-sum	severance	payments	primarily	based	on	years	of	service,	the	majority	of	which	are	expected	to	be	paid	over	the	next	several	quarters. As	of	December	31,	2015,	we	have	paid	approximately	$18	million	in	severance	payments	associated	with	these	actions.

In	connection	with	the	Sikorsky	acquisition,	we	assumed	obligations	related	to	certain	restructuring	actions	committed	to	by	Sikorsky	in	June	2015.	These	actions included	a	global	workforce	reduction	of	approximately	1,400	production-related	positions	and	facilities	consolidations.	As	of	December	31,	2015,	accrued	restructuring costs	associated	with	these	actions	are	approximately	$15	million,	all	of	which	are	expected	to	be	paid	in	2016.	Net	of	amounts	we	anticipate	to	recover	through	the pricing	of	our	products	and	services	to	our	customers,	we	also	expect	to	incur	an	additional	$40	million	of	costs	in	2016	related	to	these	actions.

During	2013,	we	recorded	charges	related	to	certain	severance	actions	totaling	$201	million,	of	which	$83	million,	$37	million	and	$81	million	related	to	our IS&GS,	MST	and	Space	Systems	business	segments	(prior	to	realignment).	These	charges	reduced	our	2013	net	earnings	by	$130	million	($.40	per	share)	and	primarily related	to	a	plan	we	committed	to	in	November	2013	to	close	and	consolidate	certain	facilities	and	reduce	our	total	workforce	by	approximately	4,000	positions.	These charges	also	include	$30	million	related	to	certain	severance	actions	that	occurred	in	the	first	quarter	of	2013,	which	were	subsequently	paid	in	2013.

The	November	2013	plan	resulted	from	a	strategic	review	of	these	businesses'	facility	capacity	and	future	workload	projections.	Upon	separation,	terminated employees	receive	lump-sum	severance	payments	primarily	based	on	years	of	service.	As	of	December	31,	2015,	we	have	paid	approximately	$153	million	in	severance payments	associated	with	this	action,	of	which	approximately	$46	million,	$92	million	and	$15	million	was	paid	in	2015,	2014	and	2013,	respectively.	The	remaining severance	payments	are	expected	to	be	paid	in	2016.

We	also	expect	to	incur	total	accelerated	costs	(e.g.,	accelerated	depreciation	expense	related	to	long-lived	assets	at	sites	closed)	and	incremental	costs	(e.g., relocation	of	equipment	and	other	employee	related	costs)	of	approximately	$10	million,	$50	million	and	$180	million	at	our	IS&GS,	MST	and	Space	Systems	business segments	through	the	completion	of	this	plan	in	2016.	As	of	December	31,	2015,	we	have	incurred	total	accelerated	and	incremental	costs	of	approximately	$225 million,	of	which	approximately	$115	million,	$90	million	and	$20	million	was	recorded	in	2015,	2014	and	2013,	respectively.	The	accelerated	and	incremental	costs are	recorded	as	incurred	in	cost	of	sales	on	our	Statements	of	Earnings	and	included	in	the	respective	business	segment's	results	of	operations.

We	expect	 to	recover	a	substantial	amount	of	 the	restructuring	charges	 through	 the	pricing	of	our	products	and	services	 to	 the	U.S.	Government	and	other customers,	with	the	impact	included	in	the	respective	business	segment's	results	of	operations.	Of	the	total	severance,	accelerated	and	incremental	costs	mentioned above,	we	recovered	approximately	$65	million	in	2015	and	$50	million	in	2014	and	expect	to	recover	approximately	$60	million	in	2016.

# Other	Unallocated,	Net

Other	unallocated,	net	primarily	includes	the	FAS/CAS	pension	adjustment	as	described	in	the	Business	Segment	Results	of	Operations	section	below,	stock-based compensation	and	other	corporate	costs.	These	items	are	not	allocated	to	the	business	segments	and,	therefore,	are	excluded	from	the	cost	of	sales	for	products	and services.	Other	unallocated,	net	was	$187	million	of	income	in	2015,	$132	million	of	income	in	2014	and	$841	million	of	expense	in	2013.

The	fluctuation	between	each	respective	period	was	primarily	attributable	to	the	change	in	the	FAS/CAS	pension	adjustment	to	income	of	$471	million	in	2015	and $376	million	in	2014,	compared	to	expense	of	$482	million	in	2013,	partially	offset	by	fluctuations	in	other	costs	associated	with	various	corporate	items,	none	of	which were	individually	significant.	The	changes	in	the	FAS/CAS	pension	adjustment	between	the	periods	were	attributable	to	various	items	impacting	the	calculations	of financial	accounting	standards	(FAS)	pension	expense	and	U.S.	Government	Cost	Accounting	Standards	(CAS)	pension	cost.	FAS	pension	expense	in	2015	and	2014 was	less	than	2013	primarily	due	to	the	June	2014	plan	amendments	to	certain	of	our	defined	benefit	pension	plans	to	freeze	future	retirement	benefits,	partially	offset by	the	impact	of	using	new	longevity	(also	known	as	mortality)	assumptions	(Note	11).	The	higher	CAS	pension	cost	in	2015	and	2014	compared	to	2013	primarily reflects	the	impact	of	phasing	in	CAS	Harmonization.	See	"Critical	Accounting	Policies	–	Postretirement	Benefit	Plans"	for	more	discussion	of	our	CAS	pension	cost.

# Other	Income,	Net

Other	income,	net	primarily	includes	our	share	of	earnings	or	losses	from	equity	method	investees	and	other	various	items.	Other	income,	net	in	2015	was	$236 million,	compared	to	$337	million	in	2014	and	$318	million	in	2013.	The	decrease	in	2015,	compared	to	2014,	was	primarily	due	to	a	$90	million	non-cash	impairment charge	related	to	our	decision	to	divest	Lockheed	Martin	Commercial	Flight	Training	(LMCFT)	in	2016	and	non-recoverable	transaction	costs	of	approximately	$45 million	associated	with	the	Sikorsky	acquisition	and	the	strategic	review	of	our	government	IT	and	technical	services	businesses,	partially	offset	by	fluctuations	in	other various	costs,	none	of	which	were	individually	significant.	The	asset	impairment	charge	was	partially	offset	by	a	net	deferred	tax	benefit	related	to	LMCFT	of	about $80	million,	which	is	recorded	in	income	tax	expense.	Earnings	from	equity	method	investees	in	2015	were	comparable	to	2014	(reflecting	decreased	earnings	from equity	method	investees	in	our	Space	Systems	business	segment,	offset	by	increased	earnings	form	Sikorsky	equity	method	investees).	The	increase	in	2014,	compared to	2013,	was	primarily	due	to	fluctuations	in	earnings	from	equity	method	investees	in	our	Aeronautics	and	Space	Systems	business	segments,	as	discussed	in	the "Business	Segment	Results	of	Operations"	section	below.

# Interest	Expense

Interest	expense	in	2015	was	$443	million,	compared	to	$340	million	in	2014	and	$350	million	in	2013.	The	increase	in	interest	expense	in	2015	relates	to	debt	we incurred	to	fund	the	acquisition	of	Sikorsky,	and	the	issuance	of	notes	in	February	of	2015	for	general	corporate	purposes.	See	"Capital	Structure,	Resources	and	Other" for	a	discussion	of	our	debt.

# Other	Non-Operating	Income,	Net

Other	non-operating	income,	net	increased	$24	million	from	2014	to	2015	primarily	due	to	a	gain	from	the	sale	of	an	investment	in	2015.	Other	non-operating income,	net	in	2014	was	comparable	to	2013.

# Income	Tax	Expense

Our	effective	income	tax	rate	from	continuing	operations	was	28.2%	for	2015,	31.3%	for	2014,	and	29.0%	for	2013.	The	rates	for	all	periods	benefited	from	tax deductions	for	U.S.	manufacturing	activities,	deductions	for	dividends	paid	to	our	defined	contribution	plans	with	an	employee	stock	ownership	plan	feature	and	the retroactive	reinstatement	of	the	U.S.	research	and	development	(R&D)	tax	credit.	These	benefits	were	partially	offset	by	the	unfavorable	impacts	of	the	non-cash goodwill	impairment	charges	in	2014	and	2013.	The	U.S.	manufacturing	deduction	benefit	for	2015,	2014	and	2013	reduced	our	effective	tax	rate	by	approximately	two percentage	points.

In	2015,	the	R&D	tax	credit	was	permanently	extended	and	reinstated,	retroactive	to	the	beginning	of	2015,	which	reduced	our	effective	income	tax	rate	by	1.4 percentage	points.	In	2014,	the	R&D	tax	credit	was	temporarily	reinstated	for	one	year,	retroactive	to	the	beginning	of	2014,	which	reduced	our	effective	tax	rate	by	0.9 percentage	point.	In	2013,	the	R&D	tax	credit	was	temporarily	reinstated	for	two	years,	retroactive	to	the	beginning	of	2012.	As	a	result,	the	effective	income	tax	rate	for 2013	reflects	the	credit	for	all	of	2013	and	2012,	which	reduced	our	effective	tax	rate	by	1.8	percentage	points.

As	a	result	of	electing	to	treat	the	acquisition	of	the	stock	of	Sikorsky	as	an	asset	acquisition	under	section	338(h)(10)	of	the	Internal	Revenue	Code,	we	expect	tax deductions	for	the	amortization	of	intangibles	and	goodwill	over	15	years	to	reduce	our	tax	payments	by	a	net	present	value	of	approximately	$1.9	billion.

As	a	result	of	a	decision	in	2015	to	divest	LMCFT	in	2016,	we	recorded	an	asset	impairment	charge	of	approximately	$90	million.	This	charge	was	partially	offset by	a	net	deferred	tax	benefit	of	about	$80	million.	The	net	impact	of	the	resulting	tax	benefit	reduced	the	effective	income	tax	rate	by	1.0	percentage	point	in	2015.

A	limited	amount	of	the	non-cash	goodwill	impairment	charges	will	be	deductible	for	tax	purposes.	Accordingly,	the	non-cash	goodwill	impairment	charges increased	our	effective	income	tax	rates	by	0.6	percentage	point	for	2014	and	1.2	percentage	points	for	2013	(Note	1).

Future	changes	in	tax	law	could	significantly	impact	our	provision	for	income	taxes,	the	amount	of	taxes	payable,	and	our	deferred	tax	asset	and	liability	balances. Recent	proposals	to	lower	the	U.S.	corporate	income	tax	rate	would	require	us	to	reduce	our	net	deferred	tax	assets	upon	enactment	of	new	tax	legislation,	with	a corresponding	material,	one-time,	non-cash	increase	in	income	tax	expense,	but	our	income	tax	expense	and	payments	would	be	materially	reduced	in	subsequent	years. Our	net	deferred	tax	assets	as	of	December	31,	2015	and	2014	were	$5.9	billion	and	$5.5	billion,	based	on	a	35%	Federal	statutory	income	tax	rate,	and	primarily	relate to	our	postretirement	benefit	plans.	If	legislation	reducing	the	Federal	statutory	income	tax	rate	to	25%	had	been	enacted	at	December	31,	2015,	our	net	deferred	tax assets	would	have	been	reduced	by	$1.7	billion	and	we	would	have	recorded	a	corresponding	one-time,	non-cash	increase	in	income	tax	expense	of	$1.7	billion.	This additional	expense	would	be	less	if	the	legislation	phased	in	the	tax	rate	reduction	or	if	the	final	rate	was	higher	than	25%.	The	amount	of	net	deferred	tax	assets	will change	 periodically	 based	 on	 several	 factors,	 including	 the	 measurement	 of	 our	 postretirement	 benefit	 plan	 obligations	 and	 actual	 cash	 contributions	 to	 our postretirement	benefit	plans.

# Net	Earnings	from	Continuing	Operations

We	reported	net	earnings	from	continuing	operations	of	$3.6	billion	($11.46	per	share)	in	2015,	$3.6	billion	($11.21	per	share)	in	2014	and	$3.0	billion	($9.04	per share)	in	2013.	Both	net	earnings	and	earnings	per	share	from	continuing	operations	were	affected	by	the	factors	mentioned	above.	Earnings	per	share	also	benefited from	a	net	decrease	of	approximately	eleven	million	common	shares	outstanding	from	December	31,	2014	to	December	31,	2015	and	approximately	five	million common	shares	outstanding	from	December	31,	2013	to	December	31,	2014	as	a	result	of	share	repurchases,	which	were	partially	offset	by	share	issuance	under	our stock-based	awards	and	certain	defined	contribution	plans.

# Net	Earnings	from	Discontinued	Operations

Net	earnings	from	discontinued	operations	for	2013	include	a	benefit	of	$31	million	resulting	from	the	resolution	of	certain	tax	matters	related	to	a	business	sold prior	to	2013.

# Business	Segment	Results	of	Operations

We	operate	in	five	business	segments:	Aeronautics,	IS&GS,	MFC,	MST	and	Space	Systems.	We	organize	our	business	segments	based	on	the	nature	of	products and	services	offered.	Net	sales	of	our	business	segments	exclude	intersegment	sales	as	these	activities	are	eliminated	in	consolidation.	The	amounts,	discussion	and presentation	of	our	business	segments	as	set	forth	in	this	Annual	Report	on	Form	10-K	reflect	the	program	realignment	described	above	for	all	periods	presented	and include	the	results	of	the	acquired	Sikorsky	business	from	the	November	6,	2015	acquisition	date	through	December	31,	2015.

Operating	profit	of	our	business	segments	includes	our	share	of	earnings	or	losses	from	equity	method	investees	because	the	operating	activities	of	the	equity method	investees	are	closely	aligned	with	the	operations	of	our	business	segments.	United	Launch	Alliance	(ULA),	which	is	part	of	our	Space	Systems	business segment,	is	our	primary	equity	method	investee.	Operating	profit	of	our	business	segments	excludes	the	FAS/CAS	pension	adjustment	described	below;	expense	for stock-based	compensation;	the	effects	of	items	not	considered	part	of	management's	evaluation	of	segment	operating	performance,	such	as	charges	related	to	goodwill impairments	(Note	1)	and	significant	severance	actions	(Note	15);	gains	or	losses	from	divestitures	(Note	3);	the	effects	of	certain	legal	settlements;	corporate	costs	not allocated	to	our	business	segments;	and	other	miscellaneous	corporate	activities.	These	items	are	included	in	the	reconciling	item	"Unallocated	items"	between	operating profit	from	our	business	segments	and	our	consolidated	operating	profit.

Our	business	segments'	results	of	operations	include	pension	expense	only	as	calculated	under	U.S.	Government	Cost	Accounting	Standards,	which	we	refer	to	as CAS	pension	cost.	We	recover	CAS	pension	cost	through	the	pricing	of	our	products	and	services	on	U.S.	Government	contracts	and,	therefore,	the	CAS	pension	cost	is recognized	in	each	of	our	business	segments'	net	sales	and	cost	of	sales.	Since	our	consolidated	financial	statements	must	present	pension	expense	calculated	in accordance	with	FAS	requirements	under	U.S.	generally	accepted	accounting	principles	(GAAP),	which	we	refer	to	as	FAS	pension	expense,	the	FAS/CAS	pension adjustment	increases	or	decreases	the	CAS	pension	cost	recorded	in	our	business	segments'	results	of	operations	to	equal	the	FAS	pension	expense.	As	a	result,	to	the extent	that	CAS	pension	cost	exceeds	FAS	pension	expense,	which	occurred	for	2015	and	2014,	we	have	FAS/CAS	pension	income	and,	conversely,	to	the	extent	FAS pension	expense	exceeds	CAS	pension	cost,	which	occurred	for	2013,	we	have	FAS/CAS	pension	expense.

The	operating	results	in	the	following	tables	exclude	businesses	included	in	discontinued	operations	(Note	13)	for	all	years	presented.	Summary	operating	results for	each	of	our	business	segments	were	as	follows	(in	millions):

(a) FAS	pension	expense	in	2015	and	2014	was	less	than	in	2013	primarily	due	to	the	June	2014	plan	amendments	to	certain	of	our	defined	benefit	pension	plans	to	freeze	future retirement	benefits,	partially	offset	by	the	impact	of	using	new	longevity	assumptions	(Note	11).

(b) The	higher	CAS	pension	cost	primarily	reflects	the	impact	of	phasing	in	CAS	Harmonization.

(c) We	expect	FAS/CAS	pension	income	in	2016	of	about	$975	million	as	further	discussed	in	"Critical	Accounting	Policies	–	Postretirement	Benefit	Plans"	below.

(d) We	 recognized	 non-cash	 goodwill	 impairment	 charges	 related	 to	 the	 Technical	 Services	 reporting	 unit	 within	 our	 MFC	 business	 segment	 in	 2014	 and	 2013.	 For	 more information,	see	"Note	1	–	Significant	Accounting	Policies"	of	our	consolidated	financial	statements.

(e) See	"Consolidated	Results	of	Operations	–	Restructuring	Charges"	for	information	on	charges	related	to	certain	severance	actions	at	our	business	segments.	Severance	charges for	initiatives	that	are	not	significant	are	included	in	business	segment	operating	profit.

(f) Other,	net	in	2015	includes	a	non-cash	asset	impairment	charge	of	approximately	$90	million	related	to	our	decision	to	divest	LMCFT	in	2016.	This	charge	was	partially	offset by	a	net	deferred	tax	benefit	of	about	$80	million,	which	is	recorded	in	income	tax	expense.	The	net	impact	reduced	net	earnings	by	about	$10	million.

(g) Other,	 net	 in	 2015	 includes	 approximately	 $45	 million	 of	 non-recoverable	 transaction	 costs	 associated	 with	 the	 acquisition	 of	 Sikorsky	 and the	 strategic review	 of	 our government	IT	and	technical	services	businesses.

The	following	segment	discussions	also	include	information	relating	to	backlog	for	each	segment.	Backlog	was	approximately	$99.6	billion,	$80.5	billion	and $82.6	billion	at	December	31,	2015,	2014	and	2013.	Backlog	at	December	31,	2015	includes	approximately	$15.6	billion	of	Sikorsky	backlog	and	$4.8	billion	of backlog	related	to	our	IS&GS	business	segment,	which	we	plan	to	divest	in	2016.	These	amounts	included	both	funded	backlog	(firm	orders	for	which	funding	has	been both	authorized	and	appropriated	by	the	customer	–	Congress	in	the	case	of	U.S.	Government	agencies)	and	unfunded	backlog	(firm	orders	for	which	funding	has	not	yet been	appropriated).	Backlog	does	not	include	unexercised	options	or	task	orders	to	be	issued	under	indefinite-delivery,	indefinite-quantity	contracts.	Funded	backlog was	approximately	$70.7	billion	at	December	31,	2015.

Management	evaluates	performance	on	our	contracts	by	focusing	on	net	sales	and	operating	profit	and	not	by	type	or	amount	of	operating	expense.	Consequently, our	discussion	of	business	segment	performance	focuses	on	net	sales	and	operating	profit,	consistent	with	our	approach	for	managing	the	business.	This	approach	is consistent	throughout	the	life	cycle	of	our	contracts,	as	management	assesses	the	bidding	of	each	contract	by	focusing	on	net	sales	and	operating	profit	and	monitors performance	on	our	contracts	in	a	similar	manner	through	their	completion.

We	regularly	provide	customers	with	reports	of	our	costs	as	the	contract	progresses.	The	cost	information	in	the	reports	is	accumulated	in	a	manner	specified	by	the requirements	of	each	contract.	For	example,	cost	data	provided	to	a	customer	for	a	product	would	typically	align	to	the	subcomponents	of	that	product	(such	as	a	wing- box	on	an	aircraft)	and	for	services	would	align	to	the	type	of	work	being	performed	(such	as	help-desk	support).	Our	contracts	generally	are	cost-based,	which	allows for	the	recovery	of	costs	in	the	pricing	of	our	products	and	services.	Most	of	our	contracts	are	bid	and	negotiated	with	our	customers	under	circumstances	in	which	we are	required	to	disclose	our	estimated	total	costs	to	provide	the	product	or	service.	This	approach	for	negotiating	contracts	with	our	U.S.	Government	customers generally	allows	for	the	recovery	of	our	costs.	We	also	may	enter	into	long-term	supply	contracts	for	certain	materials	or	components	to	coincide	with	the	production schedule	of	certain	products	and	to	ensure	their	availability	at	known	unit	prices.

Many	of	our	contracts	span	several	years	and	include	highly	complex	technical	requirements.	At	the	outset	of	a	contract,	we	identify	and	monitor	risks	to	the achievement	of	the	technical,	schedule	and	cost	aspects	of	the	contract	and	assess	the	effects	of	those	risks	on	our	estimates	of	total	costs	to	complete	the	contract.	The estimates	consider	the	technical	requirements	(e.g.,	a	newly-developed	product	versus	a	mature	product),	the	schedule	and	associated	tasks	(e.g.,	the	number	and	type	of milestone	events)	and	costs	(e.g.,	material,	labor,	subcontractor,	overhead	and	the	estimated	costs	to	fulfill	our	industrial	cooperation	agreements	required	under	certain contracts	with	international	customers).	The	initial	profit	booking	rate	of	each	contract	considers	risks	surrounding	the	ability	to	achieve	the	technical	requirements, schedule	and	costs	in	the	initial	estimated	total	costs	to	complete	the	contract.	Profit	booking	rates	may	increase	during	the	performance	of	the	contract	if	we	successfully retire	risks	surrounding	the	technical,	schedule	and	cost	aspects	of	the	contract	which	decreases	the	estimated	total	costs	to	complete	the	contract.	Conversely,	our	profit booking	rates	may	decrease	if	the	estimated	total	costs	to	complete	the	contract	increase.	All	of	the	estimates	are	subject	to	change	during	the	performance	of	the	contract and	may	affect	the	profit	booking	rate.

We	have	a	number	of	programs	that	are	designated	as	classified	by	the	U.S.	Government	which	cannot	be	specifically	described.	The	operating	results	of	these classified	programs	are	included	in	our	consolidated	and	business	segment	results	and	are	subjected	to	the	same	oversight	and	internal	controls	as	our	other	programs.

Our	net	sales	are	primarily	derived	from	long-term	contracts	for	products	and	services	provided	to	the	U.S.	Government	as	well	as	FMS	contracted	through	the	U.S. Government.	We	 account	 for	 these	 contracts,	 as	 well	 as	 product	 contracts	 with	 non-U.S.	 Government	 customers,	 using	 the	 percentage-of-completion	 method	 of accounting,	which	represent	substantially	all	of	our	net	sales.	We	derive	our	remaining	net	sales	from	contracts	to	provide	services	to	non-U.S.	Government	customers, which	we	account	for	under	the	services	method	of	accounting.

Under	the	percentage-of-completion	method	of	accounting,	we	record	sales	on	contracts	based	upon	our	progress	towards	completion	on	a	particular	contract	as well	as	our	estimate	of	the	profit	to	be	earned	at	completion.	Cost-reimbursable	contracts	provide	for	the	payment	of	allowable	costs	plus	a	fee.	For	fixed-priced contracts,	net	sales	and	cost	of	sales	are	recognized	as	products	are	delivered	or	as	costs	are	incurred.	Due	to	the	nature	of	the	percentage-of-completion	method	of accounting,	changes	in	our	cost	of	sales	are	typically	accompanied	by	a	related	change	in	our	net	sales.

Changes	in	net	sales	and	operating	profit	generally	are	expressed	in	terms	of	volume.	Changes	in	volume	refer	to	increases	or	decreases	in	sales	or	operating	profit resulting	from	varying	production	activity	levels,	deliveries	or	service	levels	on	individual	contracts.	Volume	changes	in	segment	operating	profit	are	typically	based	on the	current	profit	booking	rate	for	a	particular	contract.

In	addition,	comparability	of	our	segment	sales,	operating	profit	and	operating	margins	may	be	impacted	favorably	or	unfavorably	by	changes	in	profit	booking rates	on	our	contracts	accounted	for	using	the	percentage-of-completion	method	of	accounting.	Increases	in	the	profit	booking	rates,	typically	referred	to	as	risk retirements,	usually	relate	to	revisions	in	the	estimated	total	costs	that	reflect	improved	conditions	on	a	particular	contract.	Conversely,	conditions	on	a	particular	contract may	deteriorate	resulting	in	an	increase	in	the	estimated	total	costs	to	complete	and	a	reduction	in	the	profit	booking	rate.	Increases	or	decreases	in	profit	booking	rates are	recognized	in	the	current	period	and	reflect	the	inception-to-date	effect	of	such	changes.	Segment	operating	profit	and	margins	may	also	be	impacted	favorably	or unfavorably	by	other	items.	Favorable	items	may	include	the	positive	resolution	of	contractual	matters,	cost	recoveries	on	restructuring	charges,	insurance	recoveries and	gains	on	sales	of	assets.	Unfavorable	items	may	include	the	adverse	resolution	of	contractual	matters;	restructuring	charges,	except	for	significant	severance	actions as	mentioned	above	which	are	excluded	from	segment	operating	results;	reserves	for	disputes;	asset	impairments;	and	losses	on	sales	of	assets.	Segment	operating	profit and	items	such	as	risk	retirements,	reductions	of	profit	booking	rates	or	other	matters	are	presented	net	of	state	income	taxes.

Our	consolidated	net	adjustments	not	related	to	volume,	including	net	profit	booking	rate	adjustments	and	other	matters,	net	of	state	income	taxes,	increased segment	operating	profit	by	approximately	$1.9	billion,	$1.8	billion	and	$2.1	billion	for	2015,	2014	and	2013.	The	increase	in	our	consolidated	net	adjustments	in	2015 compared	to	2014	was	primarily	due	to	an	increase	in	profit	booking	rate	adjustments	at	our	Space	Systems,	Aeronautics	and	IS&GS	business	segments,	offset	by	a decrease	in	profit	booking	rate	adjustments	at	our	MST	and	MFC	business	segments.	The	decrease	in	our	consolidated	net	adjustments	in	2014	compared	to	2013	was primarily	due	to	a	decrease	in	profit	booking	rate	adjustments	at	our	Aeronautics,	MFC	and	MST	business	segments.	The	consolidated	net	adjustments	for	2015	are inclusive	of	approximately	$645	million	in	unfavorable	items,	which	include	reserves	for	performance	matters	on	an	international	program	at	MST	and	on	commercial satellite	programs	at	Space	Systems.	The	consolidated	net	adjustments	for	2014	are	inclusive	of	approximately	$650	million	in	unfavorable	items,	which	include	reserves recorded	on	certain	training	and	logistics	solutions	programs	at	MST	and	net	warranty	reserve	adjustments	for	various	programs	(including	JASSM	and	GMLRS)	at MFC	as	described	in	the	respective	business	segment's	results	of	operations	below.	The	consolidated	net	adjustments	for	2013	are	inclusive	of	approximately	$600 million	in	unfavorable	items,	which	include	significant	profit	reductions	on	the	F-35	development	contract	and	on	the	C-5	program.

Our	Aeronautics	business	segment	is	engaged	in	the	research,	design,	development,	manufacture,	integration,	sustainment,	support	and	upgrade	of	advanced military	aircraft,	including	combat	and	air	mobility	aircraft,	unmanned	air	vehicles	and	related	technologies.	Aeronautics'	major	programs	include	the	F-35	Lightning	II Joint	Strike	Fighter,	C-130	Hercules,	F-16	Fighting	Falcon,	C-5M	Super	Galaxy	and	F-22	Raptor.	Aeronautics'	operating	results	included	the	following	(in	millions):

|  | 2015 | 2014 | 2013 |
| :--- | :--- | :--- | :--- |
| Net\tsales | $15,570 | $14,920 | $14,123 |

| Backlog\tat\tyear-end | $31,800 | $27,600 | $28,000 |

Aeronautics'	net	sales	in	2015	increased	$650	million,	or	4%,	compared	to	2014.	The	increase	was	attributable	to	higher	net	sales	of	approximately	$1.4	billion	for F-35	production	contracts	due	to	increased	volume	on	aircraft	production	and	sustainment	activities;	and	approximately	$150	million	for	the	C-5	program	due	to increased	deliveries	(nine	aircraft	delivered	in	2015	compared	to	seven	delivered	in	2014).	The	increases	were	partially	offset	by	lower	net	sales	of	approximately	$350 million	for	the	C-130	program	due	to	fewer	aircraft	deliveries	(21	aircraft	delivered	in	2015,	compared	to	24	delivered	in	2014),	lower	sustainment	activities	and	aircraft contract	mix;	approximately	$200	million	due	to	decreased	volume	and	lower	risk	retirements	on	various	programs;	approximately	$195	million	for	the	F-16	program due	to	fewer	deliveries	(11	aircraft	delivered	in	2015,	compared	to	17	delivered	in	2014);	and	approximately	$190	million	for	the	F-22	program	as	a	result	of	decreased sustainment	activities.

Aeronautics'	operating	profit	 in	2015	 increased	$32	million,	or	2%,	compared	 to	2014.	Operating	profit	 increased	by	approximately	$240	million	for	F-35 production	contracts	due	to	increased	volume	and	risk	retirements;	and	approximately	$40	million	for	the	C-5	program	due	to	increased	risk	retirements.	These	increases were	offset	by	lower	operating	profit	of	approximately	$90	million	for	the	F-22	program	due	to	lower	risk	retirements;	approximately	$70	million	for	the	C-130	program as	 a	 result	 of	 the	 reasons	 stated	 above	 for	 lower	 net	 sales;	 and	 approximately	 $80	 million	 due	 to	 decreased	 volume	 and	 risk	 retirements	 on	 various	 programs. Adjustments	not	related	to	volume,	including	net	profit	booking	rate	adjustments	and	other	matters,	were	approximately	$100	million	higher	in	2015	compared	to	2014.

Aeronautics'	net	sales	increased	$797	million,	or	6%,	in	2014	as	compared	to	2013.	The	increase	was	primarily	attributable	to	higher	net	sales	of	approximately $790	million	for	F-35	production	contracts	due	to	increased	volume	and	sustainment	activities;	about	$55	million	for	the	F-16	program	due	to	increased	deliveries	(17 aircraft	delivered	in	2014	compared	to	13	delivered	in	2013)	partially	offset	by	contract	mix;	and	approximately	$45	million	for	the	F-22	program	due	to	increased	risk retirements.	The	increases	were	partially	offset	by	lower	net	sales	of	approximately	$55	million	for	the	F-35	development	contract	due	to	decreased	volume,	partially offset	by	the	absence	in	2014	of	the	downward	revision	to	the	profit	booking	rate	that	occurred	in	2013;	and	about	$40	million	for	the	C-130	program	due	to	fewer deliveries	(24	aircraft	delivered	in	2014	compared	to	25	delivered	in	2013)	and	decreased	sustainment	activities,	partially	offset	by	contract	mix.

Aeronautics'	operating	profit	increased	$37	million,	or	2%,	in	2014	as	compared	to	2013.	The	increase	was	primarily	attributable	to	higher	operating	profit	of approximately	$85	million	for	the	F-35	development	contract	due	to	the	absence	in	2014	of	the	downward	revision	to	the	profit	booking	rate	that	occurred	in	2013;	about $75	million	for	the	F-22	program	due	to	increased	risk	retirements;	approximately	$50	million	for	the	C-130	program	due	to	increased	risk	retirements	and	contract	mix, partially	offset	by	fewer	deliveries;	and	about	$25	million	for	the	C-5	program	due	to	the	absence	in	2014	of	the	downward	revisions	to	the	profit	booking	rate	that occurred	in	2013.	The	increases	were	partially	offset	by	lower	operating	profit	of	approximately	$130	million	for	the	F-16	program	due	to	decreased	risk	retirements, partially	offset	by	increased	deliveries;	and	about	$70	million	for	sustainment	activities	due	to	decreased	risk	retirements	and	volume.	Operating	profit	was	comparable for	F-35	production	contracts	as	higher	volume	was	offset	by	lower	risk	retirements.	Adjustments	not	related	to	volume,	including	net	profit	booking	rate	adjustments and	other	matters,	were	approximately	$105	million	lower	for	2014	compared	to	2013.

Backlog	increased	in	2015	compared	to	2014	primarily	due	to	higher	orders	on	F-35	and	C-130	programs.	Backlog	decreased	slightly	in	2014	compared	to	2013 primarily	due	to	lower	orders	on	F-16	and	F-22	programs.

# Trends

We	expect	Aeronautics'	2016	net	sales	to	increase	in	the	mid-single	digit	percentage	range	as	compared	to	2015	due	to	increased	volume	on	the	F-35	and	C-130 programs,	partially	offset	by	decreased	volume	on	the	F-16	program.	Operating	profit	is	also	expected	to	increase	in	the	low	single-digit	percentage	range,	driven	by increased	volume	on	the	F-35	program	offset	by	contract	mix	that	results	in	a	slight	decrease	in	operating	margins	between	years.

Our	IS&GS	business	segment	provides	advanced	technology	systems	and	expertise,	integrated	information	technology	solutions	and	management	services	across	a broad	spectrum	of	applications	for	civil,	defense,	intelligence	and	other	government	customers.	IS&GS'	Technical	Services	business	provides	a	comprehensive	portfolio of	technical	and	sustainment	services.	IS&GS	has	a	portfolio	of	many	smaller	contracts	as	compared	to	our	other	business	segments.	IS&GS	has	been	impacted	by	the continued	downturn	in	certain	federal	agencies'	information	technology	budgets	and	increased	re-competition	on	existing	contracts	coupled	with	the	fragmentation	of large	contracts	into	multiple	smaller	contracts	that	are	awarded	primarily	on	the	basis	of	price.	IS&GS'	operating	results	included	the	following	(in	millions):

|  | 2015 | 2014 | 2013 |
| :--- | :--- | :--- | :--- |
| Net\tsales | $5,596 | $5,654 | $6,115 |
| Operating\tprofit | 508 | 472 | 498 |
| Operating\tmargins | 9.1% | 8.3% | 8.1% |
| Backlog\tat\tyear-end | $4,800 | $6,000 | $6,300 |

IS&GS'	net	sales	decreased	$58	million,	or	1%,	in	2015	as	compared	to	2014.	The	decrease	was	attributable	to	lower	net	sales	of	approximately	$395	million	as	a result	of	key	program	completions,	lower	customer	funding	levels	and	increased	competition,	coupled	with	the	fragmentation	of	existing	large	contracts	into	multiple smaller	contracts	that	are	awarded	primarily	on	the	basis	of	price	when	re-competed	(including	CMS-CITIC).	These	decreases	were	partially	offset	by	higher	net	sales	of approximately	$230	million	for	businesses	acquired	in	2014;	and	approximately	$110	million	due	to	the	start-up	of	new	programs	and	growth	in	recently	awarded programs.

IS&GS'	operating	profit	increased	$36	million,	or	8%,	in	2015	as	compared	to	2014.	The	increase	was	attributable	to	improved	program	performance	and	risk retirements,	offset	by	decreased	operating	profit	resulting	from	the	activities	mentioned	above	for	net	sales.	Adjustments	not	related	to	volume,	including	net	profit booking	rate	adjustments	and	other	matters,	were	approximately	$70	million	higher	in	2015	compared	to	2014.

IS&GS'	net	sales	decreased	$461	million,	or	8%,	in	2014	as	compared	to	2013.	The	decrease	was	primarily	attributable	to	lower	net	sales	of	about	$475	million	due to	the	wind-down	or	completion	of	certain	programs,	driven	by	reductions	in	direct	warfighter	support	(including	JIEDDO);	and	approximately	$320	million	due	to decreased	volume	in	technical	services	programs	reflecting	market	pressures.	The	decreases	were	offset	by	higher	net	sales	of	about	$330	million	due	to	the	start-up	of new	programs,	growth	in	recently	awarded	programs	and	integration	of	recently	acquired	companies.

IS&GS'	operating	profit	decreased	$26	million,	or	5%,	in	2014	as	compared	to	2013.	The	decrease	was	primarily	attributable	to	the	activities	mentioned	above	for sales,	partially	offset	by	severance	recoveries	related	to	the	restructuring	announced	in	November	2013	of	approximately	$20	million	in	2014.	Adjustments	not	related	to volume,	including	net	profit	booking	rate	adjustments,	were	comparable	in	2014	and	2013.

Backlog	decreased	in	2015	compared	to	2014	primarily	due	to	sales	being	recognized	on	several	multi-year	programs	(such	as	HMSC,	NISC	III,	CIOG	and	NSF ASC)	related	to	prior	year	awards	and	a	limited	number	of	large	new	business	awards.	Backlog	decreased	in	2014	compared	to	2013	primarily	due	to	lower	customer funding	levels	and	declining	activities	on	direct	warfighter	support	programs	impacted	by	defense	budget	reductions.

We	expect	IS&GS'	2016	net	sales	to	decline	in	the	high-single	digit	percentage	range	as	compared	to	2015,	primarily	driven	by	key	loss	contracts	in	an	increasingly competitive	environment,	along	with	volume	contraction	on	the	segment's	major	contracts.	Operating	profit	is	expected	to	decline	at	a	higher	percentage	range	in	2016, as	compared	to	net	sales	percentage	declines,	driven	by	higher	margin	program	losses	and	re-compete	programs	awarded	at	lower	margins.	Accordingly,	2016	margins are	expected	to	be	lower	than	2015	results.

Our	MFC	business	segment	provides	air	and	missile	defense	systems;	tactical	missiles	and	air-to-ground	precision	strike	weapon	systems;	logistics;	fire	control systems;	mission	operations	support,	readiness,	engineering	support	and	integration	services;	manned	and	unmanned	ground	vehicles;	and	energy	management	solutions. MFC's	major	programs	include	PAC-3,	THAAD,	Multiple	Launch	Rocket	System,	Hellfire,	JASSM,	Javelin,	Apache,	Sniper ®,	Low	Altitude	Navigation	and	Targeting Infrared	for	Night	(LANTIRN®)	and	SOF	CLSS.	MFC's	operating	results	included	the	following	(in	millions):

|  | 2015 | 2014 | 2013 |
| :--- | :--- | :--- | :--- |
| Net\tsales | $6,770 | $7,092 | $6,795 |

| Backlog\tat\tyear-end | $15,500 | $13,300 | $14,300 |

MFC's	net	sales	in	2015	decreased	$322	million,	or	5%,	compared	to	the	same	period	in	2014.	The	decrease	was	attributable	to	lower	net	sales	of	approximately $345	million	for	air	and	missile	defense	programs	due	to	fewer	deliveries	(primarily	PAC-3)	and	lower	volume	(primarily	THAAD);	and	approximately	$85	million	for tactical	missile	programs	due	to	fewer	deliveries	(primarily	Guided	Multiple	Launch	Rocket	System	(GMLRS))	and	Joint	Air-to-Surface	Standoff	Missile,	partially offset	by	increased	deliveries	for	Hellfire.	These	decreases	were	partially	offset	by	higher	net	sales	of	approximately	$55	million	for	energy	solutions	programs	due	to increased	volume.

MFC's	operating	profit	in	2015	decreased	$62	million,	or	5%,	compared	to	2014.	The	decrease	was	attributable	to	lower	operating	profit	of	approximately	$100 million	for	fire	control	programs	due	primarily	 to	 lower	risk	retirements	(primarily	LANTIRN	and	SNIPER);	and	approximately	$65	million	for	 tactical	missile programs	due	to	lower	risk	retirements	(primarily	Hellfire	and	GMLRS)	and	fewer	deliveries.	These	decreases	were	partially	offset	by	higher	operating	profit	of approximately	$75	million	for	air	and	missile	defense	programs	due	to	increased	risk	retirements	(primarily	THAAD).	Adjustments	not	related	to	volume,	including	net profit	booking	rate	adjustments	and	other	matters,	were	approximately	$60	million	lower	in	2015	compared	to	2014.

MFC's	net	sales	increased	$297	million,	or	4%,	in	2014	as	compared	to	2013.	The	increase	was	primarily	attributable	to	higher	net	sales	of	approximately	$180 million	for	air	and	missile	defense	programs	primarily	due	to	increased	volume	for	THAAD;	about	$115	million	for	fire	control	programs	due	to	increased	deliveries (including	Apache);	 and	 about	 $125	 million	 for	 various	 other	 programs	 due	 to	 increased	 volume.	 These	 increases	 were	 partially	 offset	 by	 lower	 net	 sales	 of approximately	$115	million	for	tactical	missile	programs	due	to	fewer	deliveries	(primarily	High	Mobility	Artillery	Rocket	System	and	Army	Tactical	Missile	System).

MFC's	operating	profit	decreased	$35	million,	or	3%,	in	2014	as	compared	to	2013.	The	decrease	was	primarily	attributable	to	lower	operating	profit	of	about	$20 million	 for	 tactical	 missile	 programs	 due	 to	 net	 warranty	 reserve	 adjustments	 for	 various	 programs	 (including	 JASSM	 and	 GMLRS)	 and	 fewer	 deliveries;	 and approximately	$45	million	for	various	other	programs	due	to	lower	risk	retirements.	The	decreases	were	offset	by	higher	operating	profit	of	approximately	$20	million for	air	and	missile	defense	programs	due	to	increased	volume	(primarily	THAAD	and	PAC-3);	and	about

$15	million	for	fire	control	programs	due	to	increased	deliveries	(primarily	Apache),	partially	offset	by	lower	risk	retirements	(primarily	Sniper®).	Adjustments	not related	to	volume,	including	net	profit	booking	rate	adjustments	and	other	matters,	were	approximately	$95	million	lower	for	2014	compared	to	2013.

Backlog	increased	in	2015	compared	to	2014	primarily	due	to	higher	orders	on	PAC-3,	LANTIRN/Sniper	and	certain	tactical	missile	programs,	partially	offset	by lower	orders	on	THAAD.	Backlog	decreased	in	2014	compared	to	2013	primarily	due	to	lower	orders	on	THAAD	and	fire	control	systems	programs,	partially	offset	by higher	orders	on	certain	tactical	missile	programs	and	PAC-3.

We	expect	MFC's	net	sales	to	be	flat	or	experience	a	slight	decline	in	2016	as	compared	to	2015.	Operating	profit	is	expected	to	decrease	by	approximately	20 percent,	driven	by	contract	mix	and	fewer	risk	retirements	in	2016	compared	to	2015.	Accordingly,	operating	profit	margin	is	expected	to	decline	from	2015	levels.

As	previously	described,	on	November	6,	2015,	we	acquired	Sikorsky	and	aligned	the	Sikorsky	business	under	our	MST	business	segment.	The	results	of	the acquired	Sikorsky	business	have	been	included	in	our	financial	results	from	the	November	6,	2015	acquisition	date	through	December	31,	2015.	As	a	result,	our consolidated	operating	results	and	MST	business	segment	operating	results	for	the	year	ended	December	31,	2015	do	not	reflect	a	full	year	of	Sikorsky	operations.

Our	MST	business	segment	provides	design,	manufacture,	service	and	support	for	a	variety	of	military	and	civil	helicopters,	ship	and	submarine	mission	and combat	systems;	mission	systems	and	sensors	for	rotary	and	fixed-wing	aircraft;	sea	and	land-based	missile	defense	systems;	radar	systems;	the	Littoral	Combat	Ship (LCS);	simulation	and	training	services;	and	unmanned	systems	and	technologies.	In	addition,	MST	supports	the	needs	of	customers	in	cybersecurity	and	delivers communication	and	command	and	control	capabilities	through	complex	mission	solutions	for	defense	applications.

| Operating\tmargins | 9.3% | 10.7% | 11.8% |
| Backlog\tat\tyear-end | $30,100 | $13,300 | $12,600 |

MST's	net	sales	in	2015	increased	$359	million,	or	4%,	compared	to	2014.	The	increase	was	attributable	to	net	sales	of	approximately	$400	million	from	Sikorsky, net	of	adjustments	required	to	account	for	the	acquisition	of	this	business	in	the	fourth	quarter	of	2015;	and	approximately	$220	million	for	integrated	warfare	systems and	 sensors	 programs,	 primarily	 due	 to	 the	 ramp-up	 of	 recently	 awarded	 programs	 (Space	 Fence).	 These	 increases	 were	 partially	 offset	 by	 lower	 net	 sales	 of approximately	$150	million	for	undersea	systems	programs	due	to	decreased	volume	as	a	result	of	in-theater	force	reductions	(primarily	Persistent	Threat	Detection System);	and	approximately	$105	million	for	ship	and	aviation	systems	programs	primarily	due	to	decreased	volume	(Merlin	Capability	Sustainment	Program).

MST's	operating	profit	in	2015	decreased	$92	million,	or	10%,	compared	to	2014.	Operating	profit	decreased	by	approximately	$75	million	due	to	performance matters	on	an	international	program;	approximately	$45	million	for	Sikorsky	due	primarily	to	intangible	amortization	and	adjustments	required	to	account	for	the acquisition	of	 this	business	 in	 the	fourth	quarter	of	2015;	and	approximately	$15	million	for	 integrated	warfare	systems	and	sensors	programs,	primarily	due	 to investments	made	in	connection	with	a	recently	awarded	next	generation	radar	technology	program,	partially	offset	by	higher	risk	retirements	(including	Halifax	Class Modernization).	These	decreases	were	partially	offset	by	approximately	$20	million	in	increased	operating	profit	for	training	and	logistics	services	programs,	primarily due	to	reserves	recorded	on	certain	programs	in	2014	that	were	not	repeated	in	2015.	Adjustments	not	related	to	volume,	including	net	profit	booking	rate	adjustments and	other	matters,	were	approximately	$100	million	lower	in	2015	compared	to	2014.

MST's	net	sales	decreased	$305	million,	or	3%,	in	2014	as	compared	to	2013.	Net	sales	decreased	by	approximately	$305	million	due	to	the	wind-down	or completion	of	certain	C4ISR	programs	(primarily	PTDS);	about	$85	million	for	undersea	systems	programs	due	to	decreased	volume	and	deliveries;	and	about	$55 million	related	to	the	settlements	of	contract	cost	matters	on	certain	programs	in	2013	that	were	not	repeated	in	2014	(including	a	portion	of	the	terminated	presidential helicopter	program).	The	decreases	were	partially	offset	by	higher	net	sales	of	approximately	$80	million	for	integrated	warfare	systems	and	sensors	programs	due	to increased	volume	(primarily	Space	Fence);	and	approximately	$40	million	for	training	and	logistics	solutions	programs	due	to	increased	deliveries	(primarily	Close Combat	Tactical	Trainer).

MST's	operating	profit	decreased	$129	million,	or	12%,	in	2014	as	compared	to	2013.	The	decrease	was	primarily	attributable	to	lower	operating	profit	of approximately	$120	million	related	to	the	settlements	of	contract	cost	matters	on	certain	programs	in	2013	that	were	not	repeated	in	2014	(including	a	portion	of	the terminated	presidential	helicopter	program);	approximately	$55	million	due	to	the	reasons	described	above	for	lower	C4ISR	program	sales,	as	well	as	performance matters	on	an	international	program;	and	approximately	$45	million	due	to	higher	reserves	recorded	on	certain	training	and	logistics	solutions	programs.	The	decreases were	partially	offset	by	higher	operating	profit	of	approximately	$45	million	for	performance	matters	and	reserves	recorded	in	2013	that	were	not	repeated	in	2014;	and about	$60	million	for	various	programs	due	to	increased	risk	retirements	(including	MH-60	and	radar	surveillance	programs).	Adjustments	not	related	to	volume, including	net	profit	booking	rate	adjustments	and	other	matters,	were	approximately	$85	million	lower	for	2014	compared	to	2013.

Backlog	increased	in	2015	compared	to	2014	primarily	due	to	the	addition	of	Sikorsky	backlog,	as	well	as	higher	orders	on	new	program	starts	(such	as	Australian Defence	Force	Pilot	Training	System).	Backlog	increased	in	2014	compared	to	2013	primarily	due	to	higher	orders	on	new	program	starts	(such	as	Space	Fence).

We	expect	MST's	2016	net	sales	to	increase	in	the	mid-double	digit	percentage	range	compared	to	2015	net	sales	due	to	the	inclusion	of	Sikorsky	programs	for	a	full year,	partially	offset	by	a	decline	in	volume	due	to	the	wind-down	or	completion	of	certain	programs.	Operating	profit	is	expected	to	be	equivalent	to	2015	on	higher volume,	and	operating	margin	is	expected	to	decline	due	to	costs	associated	with	the	Sikorsky	acquisition,	including	the	impact	of	purchase	accounting	adjustments, integration	costs	and	inherited	restructuring	costs	associated	with	actions	committed	to	by	Sikorsky	prior	to	acquisition.

Our	Space	Systems	business	segment	is	engaged	in	the	research	and	development,	design,	engineering	and	production	of	satellites,	strategic	and	defensive	missile systems	and	space	transportation	systems.

| Backlog\tat\tyear-end | $17,400 | $20,300 | $21,400 |

Space	Systems'	net	sales	in	2015	decreased	$97	million,	or	1%,	compared	to	2014.	The	decrease	was	attributable	to	approximately	$335	million	lower	net	sales	for government	satellite	programs	due	to	decreased	volume	(primarily	AEHF)	and	the	wind-down	or	completion	of	mission	solutions	programs;	and	approximately	$55 million	for	strategic	missile	and	defense	systems	due	to	lower	volume.	These	decreases	were	partially	offset	by	higher	net	sales	of	approximately	$235	million	for businesses	acquired	in	2014;	and	approximately	$75	million	for	the	Orion	program	due	to	increased	volume.

Space	Systems'	operating	profit	in	2015	decreased	$16	million,	or	1%,	compared	to	2014.	Operating	profit	increased	approximately	$85	million	for	government satellite	programs	due	primarily	to	increased	risk	retirements.	This	increase	was	offset	by	lower	operating	profit	of	approximately	$65	million	for	commercial	satellite programs	due	to	performance	matters	on	certain	programs;	and	approximately	$35	million	due	to	decreased	equity	earnings	in	joint	ventures.	Adjustments	not	related	to volume,	including	net	profit	booking	rate	adjustments	and	other	matters,	were	approximately	$105	million	higher	in	2015	compared	to	2014.

Space	Systems'	net	sales	decreased	$86	million,	or	1%,	in	2014	as	compared	to	2013.	The	decrease	was	primarily	attributable	to	lower	net	sales	of	approximately $335	million	for	government	satellite	programs	due	to	decreased	volume	(primarily	AEHF,	GPS-III	and	MUOS);	$190	million	due	to	mission	solutions'	programs transitioning	from	development	to	operations	and	support,	wind-down	or	completion	of	certain	programs,	and	defense	budget	cuts;	and	about	$45	million	for	various other	programs	due	to	decreased	volume.	The	decreases	were	partially	offset	by	higher	net	sales	of	approximately	$340	million	for	the	Orion	program	due	to	increased volume	(primarily	the	first	unmanned	test	flight	of	the	Orion	MPCV);	and	about	$145	million	for	commercial	space	transportation	programs	due	to	launch-related activities.

Space	Systems'	operating	profit	for	2014	was	comparable	to	2013.	Operating	profit	decreased	by	approximately	$20	million	for	government	satellite	programs	due to	lower	volume	(primarily	AEHF	and	GPS-III),	partially	offset	by	increased	risk	retirements	(primarily	MUOS);	and	about	$20	million	due	to	decreased	equity	earnings for	joint	ventures.	The	decreases	were	offset	by	higher	operating	profit	of	approximately	$30	million	for	the	Orion	program	due	to	increased	volume.	Operating	profit was	reduced	by	approximately	$40	million	for	charges,	net	of	recoveries,	related	to	the	restructuring	action	announced	in	November	2013.	Adjustments	not	related	to volume,	including	net	profit	booking	rate	adjustments	and	other	matters,	were	approximately	$10	million	lower	for	2014	compared	to	2013.

# Equity	earnings

Total	equity	earnings	recognized	by	Space	Systems	(primarily	ULA)	represented	approximately	$245	million,	$280	million	and	$300	million,	or	21%,	24%	and 25%	of	this	business	segment's	operating	profit	during	2015,	2014	and	2013.

Backlog	decreased	in	2015	compared	to	2014	primarily	due	to	lower	orders	for	government	satellite	programs	and	the	Orion	program	and	higher	sales	on	the	Orion program.	Backlog	decreased	in	2014	compared	to	2013	primarily	due	to	lower	orders	and	higher	sales	on	the	Orion	program,	partially	offset	by	higher	orders	on	SBIRS.

We	expect	Space	Systems'	2016	net	sales	to	decline	in	the	mid-single	digit	percentage	range	as	compared	to	2015,	primarily	driven	by	program	lifecycles	on government	satellite	programs.	Operating	profit	is	expected	to	decline	by	approximately	10	percent,	primarily	driven	by	contract	mix	and	slightly	lower	equity	earnings in	2016	compared	to	2015.	As	a	result,	operating	profit	margin	is	expected	to	decline	slightly	between	the	years.

# Liquidity	and	Cash	Flows

We	have	a	balanced	cash	deployment	strategy	to	enhance	stockholder	value	and	position	ourselves	to	take	advantage	of	new	business	opportunities	when	they	arise. Consistent	with	that	strategy,	we	have	continued	to	invest	in	our	business,	including	capital	expenditures,	independent	research	and	development	and	made	selective business	acquisitions,	while	returning	cash	to	stockholders	through	dividends	and	share	repurchases,	and	managing	our	debt	levels,	maturities	and	interest	rates.

We	 have	 generated	 strong	 operating	 cash	 flows,	 which	 have	 been	 the	 primary	 source	 of	 funding	 for	 our	 operations,	 capital	 expenditures,	 debt	 service	 and repayments,	dividends,	share	repurchases	and	postretirement	benefit	plan	contributions.	Our	strong	operating	cash	flows	enabled	our	Board	of	Directors	to	approve	two key	cash	deployment	initiatives	in	September	2015.	First,	we	increased	our	fourth	quarter	dividend	rate	by	10%	to	$1.65	per	share.	Second,	the	Board	of	Directors approved	a	$3.0	billion	increase	to	our	share	repurchase	program.	Inclusive	of	this	increase,	the	total	remaining	authorization	for	future	common	share	repurchases under	our	program	was	$3.6	billion	as	of	December	31,	2015.	Further,	based	on	a	cash	deployment	initiative	we	announced	in	October	2014,	we	plan	to	reduce	our	total outstanding	share	count	to	below	300	million	shares	by	the	end	of	2017,	market	conditions	and	our	fiduciary	obligations	permitting.	This	plan	was	not	affected	by	our acquisition	of	Sikorsky.

We	have	accessed	the	capital	markets	opportunistically	as	we	did	in	February	2015	when	we	issued	$2.25	billion	of	long-term	debt	and	as	needed	as	we	did	in November	2015	when	we	issued	$7.0	billion	of	long-term	debt	in	connection	with	our	acquisition	of	Sikorsky.	We	also	used	a	combination	of	short-term	debt	financing, commercial	 paper	 and	 available	 cash	 to	 fund	 the	 Sikorsky	 acquisition,	 as	 discussed	 in	 "Capital	 Structure,	 Resources	 and	 Other"	 and	 "Note	 10	 –	 Debt"	 of	 our consolidated	financial	statements.	We	expect	our	cash	from	operations	will	continue	to	be	sufficient	to	support	our	operations	and	anticipated	capital	expenditures	for	the foreseeable	future.	However,	we	expect	to	continue	to	issue	commercial	paper	backed	by	our	revolving	credit	facility	to	manage	the	timing	of	our	cash	flows.	We	expect to	receive	a	tax-free	special	cash	payment	of	approximately	$1.8	billion	as	a	result	of	the	anticipated	divestiture	of	our	IS&GS	business	segment	in	the	third	or	fourth quarter	of	2016	that	we	intend	to	use	to	repay	debt,	pay	dividends	or	repurchase	stock,	although	the	timing	and	closing	of	the	transaction	are	uncertain	and	subject	to obtaining	Leidos	stockholder	and	regulatory	approvals	and	receipt	of	opinions	of	tax	counsel.	As	described	in	the	"Capital	Structure,	Resources	and	Other"	section below,	we	have	financing	resources	available	to	fund	potential	cash	outflows	that	are	less	predictable	or	more	discretionary,	should	they	occur.	We	also	have	access	to credit	markets,	if	needed,	for	liquidity	or	general	corporate	purposes,	including,	but	not	limited	to,	our	revolving	credit	facility	or	the	ability	to	issue	commercial	paper, and	letters	of	credit	to	support	customer	advance	payments	and	for	other	trade	finance	purposes	such	as	guaranteeing	our	performance	on	particular	contracts.

Cash	received	from	customers,	either	from	the	payment	of	invoices	for	work	performed	or	for	advances	in	excess	of	costs	incurred,	is	our	primary	source	of	cash. We	generally	do	not	begin	work	on	contracts	until	funding	is	appropriated	by	the	customer.	However,	we	may	determine	to	fund	customer	programs	ourselves	pending government	appropriations	and	are	doing	so	with	increased	frequency.	If	we	incur	costs	in	excess	of	funds	obligated	on	the	contract,	we	may	be	at	risk	for	reimbursement of	the	excess	costs.

Billing	timetables	and	payment	terms	on	our	contracts	vary	based	on	a	number	of	factors,	including	the	contract	type.	We	generally	bill	and	collect	cash	more frequently	under	cost-reimbursable	and	time-and-materials	contracts,	which	together	represent	approximately	half	of	the	sales	we	recorded	in	2015,	as	we	are	authorized to	bill	as	the	costs	are	incurred	or	work	is	performed.	A	number	of	our	fixed-price	contracts	may	provide	for	performance-based	payments,	which	allow	us	to	bill	and collect	cash	as	we	perform	on	the	contract.	The	amount	of	performance-based	payments	and	the	related	milestones	are	encompassed	in	the	negotiation	of	each	contract. The	timing	of	such	payments	may	differ	from	our	incurrence	of	costs	related	to	our	contract	performance,	thereby	affecting	our	cash	flows.

The	U.S.	Government	has	indicated	that	it	would	consider	progress	payments	as	the	baseline	for	negotiating	payment	terms	on	fixed-price	contracts,	rather	than performance-based	payments.	In	contrast	to	negotiated	performance-based	payment	terms,	progress	payment	provisions	correspond	to	a	percentage	of	the	amount	of costs	incurred	during	the	performance	of	the	contract.	While	the	total	amount	of	cash	collected	on	a	contract	is	the	same,	performance-based	payments	have	had	a	more favorable	impact	on	the	timing	of	our	cash	flows.	In	addition,	our	cash	flows	may	be	affected	if	the	U.S.	Government	decides	to	withhold	payments	on	our	billings. While	the	impact	of	withholding	payments	delays	the	receipt	of	cash,	the	cumulative	amount	of	cash	collected	during	the	life	of	the	contract	will	not	vary.

The	majority	of	our	capital	expenditures	for	2015	and	those	planned	for	2016	are	for	equipment,	facilities	infrastructure	and	information	technology.	Expenditures for	equipment	and	facilities	infrastructure	are	generally	incurred	to	support	new	and	existing	programs	across	all	of	our	business	segments.	For	example,	we	have projects	underway	in	our	Aeronautics	business	segment	for	facilities	and	equipment	to	support	higher	production	of	the	F-35	combat	aircraft.	In	addition,	we	have projects	underway	to	modernize	certain	of	our	facilities,	inclusive	of	our	efforts	to	consolidate	and	reduce	leased	facilities.	We	also	incur	capital	expenditures	for information	technology	to	support	programs	and	general	enterprise	information	technology	infrastructure,	inclusive	of	costs	for	the	development	or	purchase	of	internal- use	software.

The	following	table	provides	a	summary	of	our	cash	flow	information	followed	by	a	discussion	of	the	key	elements	(in	millions):

# Operating	Activities

Net	cash	provided	by	operating	activities	increased	$1.2	billion	in	2015	compared	to	2014	primarily	due	to	lower	pension	contributions,	partially	offset	by	decreases in	working	capital	and	higher	tax	payments.	The	$1.8	billion	increase	in	cash	flows	related	to	Other,	net	in	the	table	above	is	primarily	because	we	made	no	contributions to	our	heritage	qualified	defined	benefit	pension	trust	in	2015	compared	to	$2.0	billion	in	2014.	We	made	$5.0	million	in	contributions	to	our	new	Sikorsky	bargained qualified	defined	benefit	pension	plan	in	2015.	The	increase	in	cash	flows	related	to	Other,	net	was	offset	by	higher	federal	and	foreign	income	tax	payments,	net	of refunds	received,	of	approximately	$210	million	in	2015	compared	to	2014	due	primarily	to	the	absence	of	refunds	received	in	2015	(prior	year's	tax	refunds	were attributable	to	timing	of	discretionary	pension	contributions	made	during	the	fourth	quarter	of	the	respective	previous	years).	The	$474	million	decrease	in	cash	flows related	to	working	capital	(defined	as	receivables	and	inventories	less	accounts	payable	and	customer	advances	and	amounts	in	excess	of	costs	incurred)	was	attributable to	an	increase	in	receivables	due	to	timing	of	customer	collections	(primarily	F-35	contracts)	as	well	as	timing	of	production	and	billing	cycles	affecting	customer advances	and	progress	payments	applied	to	inventories	(primarily	C-130	program).	See	"Critical	Accounting	Policies	–	Postretirement	Benefit	Plans"	(under	the	caption "Funding	Considerations")	for	discussion	of	future	postretirement	benefit	plan	funding.

Net	cash	provided	by	operating	activities	decreased	$680	million	in	2014	compared	to	2013	primarily	due	to	higher	tax	payments,	net	of	refunds	received	and increases	in	working	capital.	Our	federal	and	foreign	income	tax	payments,	net	of	refunds	received,	were	approximately	$760	million	higher	in	2014	compared	to	2013 due	to	an	increase	in	net	income	and	lower	refunds	received	in	2014	(attributable	to	timing	of	discretionary	pension	contributions	made	during	the	fourth	quarter	of 2012).	The	decrease	of	$274	million	in	cash	provided	by	working	capital	(defined	as	receivables	and	inventories	less	accounts	payable	and	customer	advances	and amounts	in	excess	of	costs	incurred)	was	primarily	attributable	to	lower	cash	receipts	related	to	accounts	receivable,	primarily	timing	on	the	F-35	production	contracts (including	amounts	received	in	2013	from	resolving	U.S.	Government	contractual	withholds	that	were	not	repeated	in	2014).	Partially	offsetting	the	decreases	in operating	cash	flows	were	lower	pension	contributions	in	2014.	We	made	$2.0	billion	in	contributions	to	our	qualified	defined	benefit	pension	plans	in	2014,	compared to	$2.25	billion	in	2013.

# Investing	Activities

Net	cash	used	for	investing	activities	increased	$8.0	billion	and	$602	million	in	2015	and	2014,	respectively,	compared	to	the	prior	year,	primarily	due	to	increased acquisition	activities.	Acquisition	activities	include	both	the	acquisition	of	businesses	and	investments	in	affiliates.	We	paid	$9.0	billion	in	2015	for	the	Sikorsky acquisition,	net	of	cash	acquired	(Note	3).	We	paid	$898	million	in	2014	for	acquisition	activities,	primarily	related	to	the	acquisitions	of	Zeta,	Systems	Made	Simple, and	Industrial	Defender.	In	2013,	we	paid	$269	million	for	acquisition	activities,	primarily	related	to	the	acquisition	of	Amor	Group.

Capital	expenditures	amounted	to	$939	million	in	2015,	$845	million	in	2014	and	$836	million	in	2013.	The	majority	of	our	capital	expenditures	were	for equipment	and	facilities	infrastructure	that	generally	are	incurred	to	support	new	and	existing	programs	across	all	of	our	business	segments.	We	also	incur	capital expenditures	for	information	technology	to	support	programs	and	general	enterprise	information	technology	infrastructure,	inclusive	of	costs	for	the	development	or purchase	of	internal-use-software.

Additionally,	in	2015,	we	received	cash	proceeds	of	approximately	$165	million	related	to	three	properties	sold	in	California.

# Financing	Activities

Net	cash	provided	by	financing	activities	increased	$7.6	billion	in	2015	compared	to	2014	primarily	due	to	proceeds	from	new	debt	issuances,	partially	offset	by increased	repurchases	of	common	stock	and	higher	dividends	paid.	Net	cash	used	for	financing	activities	increased	$608	million	in	2014	compared	to	2013	primarily	due to	decreased	proceeds	from	stock	option	exercises	in	2014,	higher	dividends	paid	and	increased	repurchases	of	common	stock,	partially	offset	by	the	repayment	of	long- term	notes	in	2013.

In	February	2015,	we	received	net	proceeds	of	$2.21	billion	for	the	issuance	of	$2.25	billion	of	fixed	interest-rate	long-term	notes.	In	November	2015,	we	borrowed $7.0	billion	of	fixed	interest-rate	long-term	notes	and	received	net	proceeds	of	$6.9	billion	(the	November	2015	Notes).	These	proceeds	were	used	to	repay	$6.0	billion	of outstanding	borrowings	under	a	364-day	revolving	credit	facility	that	was	used	to	finance	a	portion	of	the	purchase	price	for	the	Sikorsky	acquisition.	Additionally,	in	the fourth	quarter	of	2015,	to	partially	finance	the	Sikorsky	acquisition	we	borrowed	and	repaid	approximately	$1.0	billion	under	our	commercial	paper	program.	See "Capital	Structure,	Resources	and	Other"	for	more	information	about	our	debt	financing	activities.

We	paid	dividends	totaling	$1.9	billion	($6.15	per	share)	in	2015,	$1.8	billion	($5.49	per	share)	in	2014	and	$1.5	billion	($4.78	per	share)	in	2013.	We	have increased	our	quarterly	dividend	rate	in	each	of	the	last	three	years,	including	a	10%	increase	in	the	quarterly	dividend	rate	in	the	fourth	quarter	of	2015.	We	declared quarterly	dividends	of	$1.50	per	share	during	each	of	the	first	three	quarters	of	2015	and	$1.65	per	share	during	the	fourth	quarter	of	2015;	$1.33	per	share	during	each of	the	first	three	quarters	of	2014	and	$1.50	per	share	during	the	fourth	quarter	of	2014;	and	$1.15	per	share	during	each	of	the	first	three	quarters	of	2013	and	$1.33	per share	during	the	fourth	quarter	of	2013.

Cash	received	from	the	issuance	of	our	common	stock	in	connection	with	employee	stock	option	exercises	during	2015,	2014	and	2013	totaled	$174	million,	$308 million	and	$827	million.	The	exercises	resulted	in	the	issuance	of	2.2	million	shares,	3.7	million	shares	and	10.0	million	shares	of	our	common	stock.

In	2013,	we	repaid	$150	million	of	long-term	notes	with	a	fixed	interest	rate	of	7.38%	due	to	their	scheduled	maturities.

# Capital	Structure,	Resources	and	Other

At	December	31,	2015,	we	held	cash	and	cash	equivalents	of	$1.1	billion.	As	of	December	31,	2015,	approximately	$400	million	of	our	cash	and	cash	equivalents was	held	outside	of	the	U.S.	by	foreign	subsidiaries.	Although	those	balances	are	generally	available	to	fund	ordinary	business	operations	without	legal	or	other restrictions,	a	significant	portion	is	not	immediately	available	to	fund	U.S.	operations	unless	repatriated.	Our	intention	is	to	permanently	reinvest	earnings	from	our foreign	subsidiaries.	While	we	do	not	intend	to	do	so,	if	this	cash	had	been	repatriated	at	the	end	of	2015,	we	estimate	that	about	$48	million	of	U.S.	federal	income	tax would	have	been	due	after	considering	foreign	tax	credits.

Our	outstanding	debt,	net	of	unamortized	discounts	and	deferred	financing	costs,	amounted	to	$15.3	billion	at	December	31,	2015	and	mainly	is	in	the	form	of publicly-issued	notes	that	bear	interest	at	fixed	rates.	As	of	December	31,	2015,	we	were	in	compliance	with	all	covenants	contained	in	our	debt	and	credit	agreements.

We	actively	seek	to	finance	our	business	in	a	manner	that	preserves	financial	flexibility	while	minimizing	borrowing	costs	to	the	extent	practicable.	We	review changes	in	financial	market	and	economic	conditions	to	manage	the	types,	amounts	and	maturities	of	our	indebtedness.	We	may	at	times	refinance	existing	indebtedness, vary	our	mix	of	variable-rate	and	fixed-rate	debt	or	seek	alternative	financing	sources	for	our	cash	and	operational	needs.

# Revolving	Credit	Facilities

On	October	9,	2015,	we	entered	into	a	new	$2.5	billion	revolving	credit	facility	(the	5-year	Facility)	with	various	banks	and	concurrently	terminated	our	existing $1.5	billion	revolving	credit	facility,	which	was	scheduled	to	expire	in	August	2016.	The	5-year	Facility,	which	expires	on	October	9,	2020,	is	available	for	general corporate	purposes.	The	undrawn	portion	of	the	5-year	Facility	is	also	available	to	serve	as	a	backup	facility	for	the	issuance	of	commercial	paper.	We	may	request	and the	banks	may	grant,	at	their	discretion,	an	increase	to	the	new	credit	facility	up	to	an	additional	$500	million.	There	were	no	borrowings	outstanding	under	the	5-year Facility	as	of	and	for	the	year	ended	December	31,	2015.

In	contemplation	of	our	acquisition	of	Sikorsky,	on	October	9,	2015,	we	also	entered	into	a	364-day	revolving	credit	facility	(the	364-day	Facility,	and	together	with the	5-year	Facility,	the	Facilities)	with	various	banks	that	provided	$7.0	billion	of	funding	for	general	corporate	purposes,	including	the	acquisition	of	Sikorsky. Concurrent	with	the	consummation	of	the	Sikorsky	acquisition,	we	borrowed	$6.0	billion	under	the	364-day	Facility.	On	November	23,	2015,	we	repaid	all	outstanding borrowings	 under	 the	 364-day	 Facility	 with	 proceeds	 received	 from	 the	 issuance	 of	 the	 November	 2015	 Notes	 described	 below	 and	 terminated	 any	 remaining commitments	of	the	lenders	under	the	364-day	Facility.

Borrowings	under	the	Facilities	are	unsecured	and	bear	interest	at	rates	based,	at	our	option,	on	a	Eurodollar	Rate	or	a	Base	Rate,	as	defined	in	the	Facilities' agreements.	Each	bank's	obligation	to	make	loans	under	the	5-year	Facility	is	subject	to,	among	other	things,	our	compliance	with	various	representations,	warranties and	covenants,	including	covenants	limiting	our	ability	and	certain	of	our	subsidiaries'	ability	to	encumber	assets	and	a	covenant	not	to	exceed	a	maximum	leverage ratio,	as	defined	in	the	5-year	Facility	agreement.

# Long-Term	Debt

On	November	23,	2015,	we	issued	$7.0	billion	of	notes	(the	November	2015	Notes)	in	a	registered	public	offering.	We	received	net	proceeds	of	$6.9	billion	from the	offering,	after	deducting	discounts	and	debt	issuance	costs,	which	are	being	amortized	as	interest	expense	over	the	life	of	the	debt.	The	November	2015	Notes	consist of:

We	may,	at	our	option,	redeem	some	or	all	of	the	November	2015	Notes	and	unpaid	interest	at	any	time	by	paying	the	principal	amount	of	notes	being	redeemed plus	any	make-whole	premium	and	accrued	and	unpaid	interest	to	the	date	of	redemption.	Interest	is	payable	on	the	2018	Notes	and	the	2020	Notes	on	May	23	and November	23	of	each	year,	beginning	on	May	23,	2016;	on	the	2023	Notes	and	the	2026	Notes	on	January	15	and	July	15	of	each	year,	beginning	on	July	15,	2016;	and on	the	2036	Notes	and	the	2046	Notes	on	May	15	and	November	15	of	each	year,	beginning	on	May	15,	2016.	The	November	2015	Notes	rank	equally	in	right	of payment	with	all	of	our	existing	unsecured	and	unsubordinated	indebtedness.	The	proceeds	of	the	November	2015	Notes	were	used	to	repay	the	$6.0	billion	of borrowings	under	our	364-day	Facility	and	for	general	Corporate	purposes.

On	February	20,	2015,	we	issued	$2.25	billion	of	notes	(the	February	2015	Notes)	in	a	registered	public	offering.	We	received	net	proceeds	of	$2.21	billion	from the	offering,	after	deducting	discounts	and	debt	issuance	costs,	which	are	being	amortized	as	interest	expense	over	the	life	of	the	debt.	The	February	2015	Notes	consist of	$750	million	maturing	in	2025	with	a	fixed	interest	rate	of	2.90%,	$500	million	maturing	in	2035	with	a	fixed	interest	rate	of	3.60%	and	$1.0	billion	maturing	in	2045 with	a	fixed	interest	rate	of	3.80%.	We	may,	at	our	option,	redeem	some	or	all	of	the	notes	at	any	time	by	paying	the	principal	amount	of	notes	being	redeemed	plus	any make-whole	premium	and	accrued	and	unpaid	interest	to	the	date	of	redemption.	Interest	on	the	notes	is	payable	on	March	1	and	September	1	of	each	year,	beginning	on September	1,	2015.	These	notes	rank	equally	in	right	of	payment	with	all	of	our	existing	unsecured	and	unsubordinated	indebtedness.	The	proceeds	of	the	February	2015 Notes	were	used	for	general	Corporate	purposes.

We	also	have	an	effective	shelf	registration	statement	on	Form	S-3	on	file	with	the	U.S.	Securities	and	Exchange	Commission	to	provide	for	the	issuance	of	an indeterminate	amount	of	debt	securities.

# Commercial	Paper

We	have	agreements	in	place	with	financial	institutions	to	provide	for	the	issuance	of	commercial	paper	backed	by	our	$2.5	billion	credit	facility.	In	connection with	the	Sikorsky	acquisition,	in	the	fourth	quarter	of	2015	we	borrowed	and	repaid	approximately	$1.0	billion	under	our	commercial	paper	program.	There	were	no commercial	paper	borrowings	outstanding	as	of	December	31,	2015.	However,	we	expect	to	continue	to	issue	commercial	paper	backed	by	our	credit	facility	to	manage the	timing	of	our	cash	flows.

# Stockholders'	Equity

Our	stockholders'	equity	was	$3.1	billion	at	December	31,	2015,	a	decrease	of	$303	million	from	December	31,	2014.	The	decrease	was	primarily	due	to	the repurchase	of	15.2	million	common	shares	for	$3.1	billion;	and	dividends	declared	of	$1.9	billion	during	the	year.	These	decreases	were	partially	offset	by	net	earnings of	$3.6	billion;	employee	stock	activity	of	$660	million	(including	the	impacts	of	stock	option	exercises,	ESOP	activity	and	stock-based	compensation);	and	the amortization	of	$850	million	in	2015	postretirement	benefit	plan	expense,	offset	by	the	re-measurements	of	our	postretirement	benefit	plans	of	$351	million.

As	we	repurchase	our	common	shares,	we	reduce	common	stock	for	the	$1	of	par	value	of	the	shares	repurchased,	with	the	excess	purchase	price	over	par	value recorded	as	a	reduction	of	additional	paid-in	capital.	Due	to	the	volume	of	repurchases	made	under	our	share	repurchase	program,	additional	paid-in	capital	was	reduced to	zero,	with	the	remainder	of	the	excess	purchase	price	over	par	value	of	$2.4	billion	recorded	as	a	reduction	of	retained	earnings	in	2015.

# Contractual	Commitments	and	Off-Balance	Sheet	Arrangements

At	December	31,	2015,	we	had	contractual	commitments	to	repay	debt,	make	payments	under	operating	leases,	settle	obligations	related	to	agreements	to	purchase goods	and	services	and	settle	tax	and	other	liabilities.	Capital	lease	obligations	were	not	material.	Payments	due	under	these	obligations	and	commitments	are	as	follows (in	millions):

|  |  | Payments	Due	By	Period | Payments	Due	By	Period |  |  |
| :--- | :--- | :--- | :--- | :--- | :--- |
|  |  | Less\tThan | Years | Years | After |
|  | Total | 1\tYear | 2\tand\t3 | 4\tand\t5 | 5\tYears |
| Long-term\tdebt\t(a) | \t$16,181 | \t\t\t\t$953 | $750 | \t\t$2,150 | $12,328 |
| Interest\tpayments | 11,224 | 623 | 1,259 | 1,192 | 8,150 |
| Other\tliabilities | 2,892 | 313 | 546 | 365 | 1,668 |
| Operating\tlease\tobligations | 793 | 205 | 289 | 165 | 134 |
| Purchase\tobligations: |  |  |  |  |  |
| Operating\tactivities | 40,455 | 18,492 | \t 15,700 | 4,792 | 1,471 |
| Capital\texpenditures | 290 | 233 | 55 | 2 | — |
| Total\tcontractual\tcash\tobligations | \t$71,835 | \t\t\t\t$20,819 | $18,599 | \t\t$8,666 | $23,751 |

(a) Long-term	debt	includes	scheduled	principal	payments	only	and	excludes	$18	million	of	debt	issued	by	a	consolidated	joint	venture,	for	which	the	debt	is	not	guaranteed	by	us.

Amounts	related	to	other	liabilities	represent	the	contractual	obligations	for	certain	long-term	liabilities	recorded	as	of	December	31,	2015.	Such	amounts	mainly include	expected	payments	under	non-qualified	pension	plans,	environmental	liabilities	and	deferred	compensation	plans.

Purchase	obligations	related	to	operating	activities	include	agreements	and	contracts	that	give	the	supplier	recourse	to	us	for	cancellation	or	nonperformance	under the	contract	or	contain	terms	that	would	subject	us	to	liquidated	damages.	Such	agreements	and	contracts	may,	for	example,	be	related	to	direct	materials,	obligations	to subcontractors	and	outsourcing	arrangements.	Total	purchase	obligations	for	operating	activities	in	the	preceding	table	include	approximately	$36.7	billion	related	to contractual	commitments	entered	into	as	a	result	of	contracts	we	have	with	our	U.S.	Government	customers.	The	U.S.	Government	generally	would	be	required	to	pay	us for	any	costs	we	incur	relative	to	these	commitments	if	they	were	to	terminate	the	related	contracts	"for	convenience"	under	the	Federal	Acquisition	Regulation	(FAR), subject	to	available	funding.	This	also	would	be	true	in	cases	where	we	perform	subcontract	work	for	a	prime	contractor	under	a	U.S.	Government	contract.	The termination	for	convenience	language	also	may	be	included	in	contracts	with	foreign,	state	and	local	governments.	We	also	have	contracts	with	customers	that	do	not include	termination	for	convenience	provisions,	including	contracts	with	commercial	customers.

Purchase	obligations	in	the	preceding	table	for	capital	expenditures	generally	include	facilities	infrastructure,	equipment	and	information	technology.

We	also	may	enter	into	industrial	cooperation	agreements,	sometimes	referred	to	as	offset	agreements,	as	a	condition	to	obtaining	orders	for	our	products	and services	from	certain	customers	in	foreign	countries.	These	agreements	are	designed	to	enhance	the	social	and	economic	environment	of	the	foreign	country	by	requiring the	contractor	to	promote	investment	in	the	country.	Offset	agreements	may	be	satisfied	through	activities	that	do	not	require	us	to	use	cash,	including	transferring technology,	providing	manufacturing	and	other	consulting	support	to	in-country	projects	and	the	purchase	by	third	parties	(e.g.,	our	vendors)	of	supplies	from	in-country vendors.	These	agreements	also	may	be	satisfied	through	our	use	of	cash	for	such	activities	as	purchasing	supplies	from	in-country	vendors,	providing	financial	support for	in-country	projects,	establishment	of	ventures	with	local	companies	and	building	or	leasing	facilities	for	in-country	operations.	We	typically	do	not	commit	to	offset agreements	until	orders	for	our	products	or	services	are	definitive.	The	amounts	ultimately	applied	against	our	offset	agreements	are	based	on	negotiations	with	the customer	and	typically	require	cash	outlays	that	represent	only	a	fraction	of	the	original	amount	in	the	offset	agreement.	The	costs	to	satisfy	our	offset	obligations	are included	in	the	estimates	of	our	total	costs	to	complete	the	contract	and	may	impact	our	profitability	and	cash	flows.	The	ability	to	recover	investments	that	we	make	is generally	dependent	upon	the	successful	operation	of	ventures	that	we	do	not	control	and	may	involve	products	and	services	that	are	dissimilar	to	our	business	activities. At	December	31,	2015,	the	remaining	obligations	under	our	outstanding	offset	agreements	totaled	$16	billion,	which	primarily	relate	to	our	Aeronautics,	MFC	and	MST business	segments,	most	of	which	extend	 through	2028.	To	 the	extent	we	have	entered	 into	purchase	obligations	at	December	31,	2015	 that	also	satisfy	offset agreements,	 those	 amounts	 are	 included	 in	 the	 preceding	 table.	 Offset	 programs	 usually	 extend	 over	 several	 years	 and	 may	 provide	 for	 penalties,	 estimated	 at approximately	$1.4	billion	at	December	31,	2015,	in	the	event	we	fail	to	perform	in	accordance	with	offset	requirements.	While	historically	we	have	not	been	required	to pay	material	penalties,	resolution	of	offset	requirements	are	often	the	result	of	negotiations	and	subjective	judgments.

In	connection	with	our	50%	ownership	interest	of	ULA,	we	and	The	Boeing	Company	(Boeing)	are	required	to	provide	ULA	an	additional	capital	contribution	if ULA	is	unable	to	make	required	payments	under	its	inventory	supply	agreement	with	Boeing.	As	of	December	31,	2015,	ULA's	total	remaining	obligation	to	Boeing under	 the	 inventory	 supply	 agreement	 was	 $120	 million.	The	 parties	 have	 agreed	 to	 defer	 the	 remaining	 payment	 obligation	 as	 it	 is	 more	 than	 offset	 by	 other commitments	to	ULA.	Accordingly,	we	do	not	expect	to	be	required	to	make	a	capital	contribution	to	ULA	under	this	agreement.

In	addition,	both	we	and	Boeing	have	cross-indemnified	each	other	for	guarantees	by	us	and	Boeing	of	the	performance	and	financial	obligations	of	ULA	under certain	launch	service	contracts.	We	believe	ULA	will	be	able	to	fully	perform	its	obligations,	as	it	has	done	through	December	31,	2015,	and	that	it	will	not	be necessary	to	make	payments	under	the	cross-indemnities	or	guarantees.

We	have	entered	into	standby	letters	of	credit,	surety	bonds	and	third-party	guarantees	with	financial	institutions	and	other	third	parties	primarily	relating	to advances	received	from	customers	and	the	guarantee	of	future	performance	on	certain	contracts.	Letters	of	credit	and	surety	bonds	generally	are	available	for	draw	down in	the	event	we	do	not	perform.	In	some	cases,	we	may	guarantee	the	contractual	performance	of	third	parties	such	as	venture	partners.	At	December	31,	2015,	we	had the	following	outstanding	letters	of	credit,	surety	bonds	and	third-party	guarantees	(in	millions):

|  |  | Commitment	Expiration	By	Period | Commitment	Expiration	By	Period |  |  |
| :--- | :--- | :--- | :--- | :--- | :--- |
|  | Total | Less\tThan | Years | Years | After |
|  | Commitment | 1\tYear | 2\tand\t3 | 4\tand\t5 | 5\tYears |
| Standby\tletters\tof\tcredit\t(a) | $2,718 | $1,374 | $408 | $811 | $125 |
| Surety\tbonds | 425 | 420 | 2 | 3 | — |
| Guarantees | 678 | 21 | 14 | 130 | 513 |
| Total\tcommitments | $3,821 | $1,815 | $424 | $944 | $638 |

(a) Approximately	$1.1	billion	of	standby	letters	of	credit	in	the	"Less	Than	1	Year"	category,	$93	million	in	the	"Years	2	and	3"	category	and	$724	million	in	the	"Years	4	and	5" category	are	expected	to	renew	for	additional	periods	until	completion	of	the	contractual	obligation.

At	December	31,	2015,	third-party	guarantees	totaled	$678	million,	of	which	approximately	79%	related	to	guarantees	of	contractual	performance	of	ventures	to which	we	currently	are	or	previously	were	a	party.	This	amount	represents	our	estimate	of	the	maximum	amount	we	would	expect	to	incur	upon	the	contractual	non- performance	of	the	venture	partners.	In	addition,	we	generally	have	cross-indemnities	in	place	that	may	enable	us	to	recover	amounts	that	may	be	paid	on	behalf	of	a

venture	partner.	We	believe	our	current	and	former	venture	partners	will	be	able	to	perform	their	obligations,	as	they	have	done	through	December	31,	2015,	and	that	it will	not	be	necessary	to	make	payments	under	the	guarantees.	In	determining	our	exposures,	we	evaluate	the	reputation,	technical	capabilities	and	credit	quality	of	our current	and	former	venture	partners.

# Critical	Accounting	Policies

# Contract	Accounting	/	Sales	Recognition

Substantially	all	of	our	net	sales	are	accounted	for	using	the	percentage-of-completion	method,	which	requires	that	significant	estimates	and	assumptions	be	made	in accounting	for	the	contracts.	Our	remaining	net	sales	are	derived	from	contracts	to	provide	services	to	non-U.S.	Government	customers,	which	we	account	for	under	a services	accounting	model.

We	evaluate	new	or	significantly	modified	contracts	with	customers	other	than	the	U.S.	Government,	to	the	extent	the	contracts	include	multiple	elements,	to determine	if	the	individual	deliverables	should	be	accounted	for	as	separate	units	of	accounting.	When	we	determine	that	accounting	for	the	deliverables	as	separate units	is	appropriate,	we	allocate	the	contract	value	to	the	deliverables	based	on	their	relative	estimated	selling	prices.	The	contracts	or	contract	modifications	we	evaluate for	multiple	elements	typically	are	long-term	in	nature	and	include	the	provision	of	both	products	and	services.	Based	on	the	nature	of	our	business,	we	generally account	for	components	of	such	contracts	using	the	percentage-of-completion	accounting	model	or	the	services	accounting	model,	as	appropriate.

We	classify	net	sales	as	products	or	services	on	our	Statements	of	Earnings	based	on	the	predominant	attributes	of	the	underlying	contract.	Most	of	our	long-term contracts	are	denominated	in	U.S.	dollars,	including	contracts	for	sales	of	military	products	and	services	to	international	governments	contracted	through	the	U.S. Government.	We	record	sales	for	both	products	and	services	under	cost-reimbursable,	fixed-price	and	time-and-materials	contracts.

# Contract	Types

# Cost-reimbursable	contracts

Cost-reimbursable	contracts,	which	accounted	for	about	43%,	40%,	and	45%	of	our	total	net	sales	in	2015,	2014,	and	2013,	provide	for	the	payment	of	allowable costs	incurred	during	performance	of	the	contract	plus	a	fee,	up	to	a	ceiling	based	on	the	amount	that	has	been	funded.	We	generate	revenue	under	two	general	types	of cost-reimbursable	contracts:	cost-plus-award-fee/incentive-fee	contracts,	which	represent	a	substantial	majority	of	our	cost-reimbursable	contracts;	and	cost-plus-fixed- fee	contracts.

Cost-plus-award-fee	contracts	provide	for	an	award	fee	that	varies	within	specified	limits	based	on	the	customer's	assessment	of	our	performance	against	a predetermined	set	of	criteria,	such	as	targets	based	on	cost,	quality,	technical	and	schedule	criteria.	Cost-plus-incentive-fee	contracts	provide	for	reimbursement	of	costs plus	a	fee	which	is	adjusted	by	a	formula	based	on	the	relationship	of	total	allowable	costs	to	total	target	costs	(incentive	based	on	cost)	or	reimbursement	of	costs	plus an	incentive	to	exceed	stated	performance	targets	(incentive	based	on	performance).	The	fixed	fee	in	a	cost-plus-fixed-fee	contract	is	negotiated	at	the	inception	of	the contract	and	that	fixed	fee	does	not	vary	with	actual	costs.

# Fixed-price	and	other	contracts

Under	fixed-price	contracts,	which	accounted	for	about	54%,	55%,	and	50%	of	our	total	net	sales	in	2015,	2014,	and	2013,	we	agree	to	perform	the	specified	work for	a	pre-determined	price.	To	the	extent	our	actual	costs	vary	from	the	estimates	upon	which	the	price	was	negotiated,	we	will	generate	more	or	less	profit	or	could	incur a	loss.	Some	fixed-price	contracts	have	a	performance-based	component	under	which	we	may	earn	incentive	payments	or	incur	financial	penalties	based	on	our performance.

Under	time-and-materials	contracts,	which	accounted	for	about	3%	of	our	total	net	sales	in	2015	and	5%	of	our	total	net	sales	in	2014	and	2013,	we	are	paid	a	fixed hourly	rate	for	each	direct	labor	hour	expended	and	we	are	reimbursed	for	allowable	material	costs	and	allowable	out-of-pocket	expenses.	To	the	extent	our	actual	direct labor	and	associated	costs	vary	in	relation	to	the	fixed	hourly	billing	rates	provided	in	the	contract,	we	will	generate	more	or	less	profit	or	could	incur	a	loss.

# Percentage-of-Completion	Method

We	record	net	sales	and	an	estimated	profit	on	a	percentage-of-completion	basis	for	cost-reimbursable	and	fixed-price	contracts	for	product	and	services	contracts with	the	U.S.	Government.

The	percentage-of-completion	method	for	product	contracts	depends	on	the	nature	of	the	products	provided	under	the	contract.	For	example,	for	contracts	that require	us	to	perform	a	significant	level	of	development	effort	in	comparison	to	the	total	value	of	the	contract	and/or	to	deliver	minimal	quantities,	sales	are	recorded using	the	cost-to-cost	method	to	measure	progress	toward	completion.	Under	the	cost-to-cost	method,	we	recognize	sales	and	an	estimated	profit	as	costs	are	incurred based	on	the	proportion	that	the	incurred	costs	bear	to	total	estimated	costs.	For	contracts	that	require	us	to	provide	a	substantial	number	of	similar	items	without	a significant	level	of	development,	we	record	sales	and	an	estimated	profit	on	a	percentage-of-completion	basis	using	units-of-delivery	as	the	basis	to	measure	progress toward	completing	the	contract.	For	contracts	to	provide	services	to	the	U.S.	Government,	sales	are	generally	recorded	using	the	cost-to-cost	method.

Award	and	incentive	fees,	as	well	as	penalties	related	to	contract	performance,	are	considered	in	estimating	sales	and	profit	rates	on	contracts	accounted	for	under the	percentage-of-completion	method.	Estimates	of	award	fees	are	based	on	past	experience	and	anticipated	performance.	We	record	incentives	or	penalties	when	there	is sufficient	information	to	assess	anticipated	contract	performance.	Incentive	provisions	that	increase	or	decrease	earnings	based	solely	on	a	single	significant	event	are	not recognized	until	the	event	occurs.

Accounting	for	contracts	using	the	percentage-of-completion	method	requires	judgment	relative	to	assessing	risks,	estimating	contract	sales	and	costs	(including estimating	award	and	incentive	fees	and	penalties	related	to	performance)	and	making	assumptions	for	schedule	and	technical	issues.	Due	to	the	number	of	years	it	may take	to	complete	many	of	our	contracts	and	the	scope	and	nature	of	the	work	required	to	be	performed	on	those	contracts,	the	estimation	of	total	sales	and	costs	at completion	is	complicated	and	subject	to	many	variables	and,	accordingly,	is	subject	to	change.	When	adjustments	in	estimated	total	contract	sales	or	estimated	total costs	are	required,	any	changes	from	prior	estimates	are	recognized	in	the	current	period	for	the	inception-to-date	effect	of	such	changes.

Our	estimates	of	costs	at	completion	of	the	contract	are	based	on	assumptions	we	make	for	variables	such	as	labor	productivity	and	availability,	the	complexity	of the	work	to	be	performed,	the	availability	of	materials,	the	length	of	time	to	complete	the	contract	(to	estimate	increases	in	wages	and	prices	for	materials),	performance by	our	subcontractors	and	the	availability	and	timing	of	funding	from	our	customer,	among	other	variables.	When	estimates	of	total	costs	to	be	incurred	on	a	contract exceed	total	estimates	of	sales	to	be	earned,	a	provision	for	the	entire	loss	on	the	contract	is	recorded	in	the	period	in	which	the	loss	is	determined.

Many	of	our	contracts	span	several	years	and	include	highly	complex	technical	requirements.	At	the	outset	of	a	contract,	we	identify	and	monitor	risks	to	the achievement	of	the	technical,	schedule	and	cost	aspects	of	the	contract	and	assess	the	effects	of	those	risks	on	our	estimates	of	total	costs	to	complete	the	contract.	The estimates	consider	the	technical	requirements	(e.g.,	a	newly-developed	product	versus	a	mature	product),	the	schedule	and	associated	tasks	(e.g.,	the	number	and	type	of milestone	events)	and	costs	(e.g.,	material,	labor,	subcontractor,	overhead	and	the	estimated	costs	to	fulfill	our	industrial	cooperation	agreements,	sometimes	referred	to as	offset	agreements,	required	under	certain	contracts	with	international	customers).	The	initial	profit	booking	rate	of	each	contract	considers	risks	surrounding	the ability	to	achieve	the	technical	requirements,	schedule	and	costs	in	the	initial	estimated	total	costs	to	complete	the	contract.	Profit	booking	rates	may	increase	during	the performance	of	the	contract	if	we	successfully	retire	risks	surrounding	the	technical,	schedule	and	cost	aspects	of	the	contract	which	decreases	the	estimated	total	costs	to complete	the	contract.	Conversely,	our	profit	booking	rates	may	decrease	if	the	estimated	total	costs	to	complete	the	contract	increase.	All	of	the	estimates	are	subject	to change	during	the	performance	of	the	contract	and	may	affect	the	profit	booking	rate.

# Services	Method

Under	a	fixed-price	service	contract,	we	are	paid	a	predetermined	fixed	amount	for	a	specified	scope	of	work	and	generally	have	full	responsibility	for	the	costs associated	with	the	contract	and	the	resulting	profit	or	loss.	We	record	net	sales	under	fixed-price	service	contracts	to	non-U.S.	Government	customers	on	a	straight-line basis	over	 the	period	of	contract	performance,	unless	evidence	suggests	 that	net	sales	are	earned	or	 the	obligations	are	fulfilled	 in	a	different	pattern.	For	cost- reimbursable	contracts	for	services	to	non-U.S.	Government	customers	that	provide	for	award	and	incentive	fees,	we	record	net	sales	as	services	are	performed,	exclusive of	award	and	incentive	fees.	Award	and	incentive	fees	are	recorded	when	they	are	fixed	or	determinable,	generally	at	the	date	the	amount	is	communicated	to	us	by	the customer.	This	approach	results	in	the	recognition	of	such	fees	at	contractual	intervals	(typically	every	six	months)	throughout	the	contract	and	is	dependent	on	the customer's	processes	for	notification	of	awards	and	issuance	of	formal	notifications.	Costs	for	all	service	contracts	are	expensed	as	incurred.

# Other	Contract	Accounting	Considerations

The	majority	of	our	sales	are	driven	by	pricing	based	on	costs	incurred	to	produce	products	or	perform	services	under	contracts	with	the	U.S.	Government.	Cost- based	pricing	is	determined	under	the	FAR.	The	FAR	provides	guidance	on	the	types	of	costs	that	are	allowable	in	establishing	prices	for	goods	and	services	under	U.S. Government	contracts.	For	example,	costs	such	as	those	related	to	charitable	contributions,	interest	expense	and	certain	advertising	and	public	relations	activities	are unallowable	and,	therefore,	not	recoverable	through	sales.	In	addition,	we	may	enter	into	advance	agreements	with	the	U.S.	Government	that	address	the	subjects	of allowability	and	allocability	of	costs	to	contracts	for	specific	matters.	For	example,	most	of	the	environmental	costs	we	incur	for	environmental	remediation	related	to sites	operated	in	prior	years	are	allocated	to	our	current	operations	as	general	and	administrative	costs	under	FAR	provisions	and	supporting	advance	agreements	reached with	the	U.S.	Government.

We	closely	monitor	compliance	with	and	the	consistent	application	of	our	critical	accounting	policies	related	to	contract	accounting.	Costs	incurred	and	allocated	to contracts	are	reviewed	for	compliance	with	U.S.	Government	regulations	by	our	personnel	and	are	subject	to	audit	by	the	Defense	Contract	Audit	Agency.

# Postretirement	Benefit	Plans

# Overview

Many	of	our	employees	participate	in	qualified	and	nonqualified	defined	benefit	pension	plans,	retiree	medical	and	life	insurance	plans	and	other	postemployment plans	(collectively,	postretirement	benefit	plans	–	see	Note	11).	The	majority	of	our	accrued	benefit	obligations	relate	to	our	qualified	defined	benefit	pension	plans	and retiree	medical	and	life	insurance	plans.	We	recognize	on	a	plan-by-plan	basis	the	net	funded	status	of	these	postretirement	benefit	plans	under	GAAP	as	either	an	asset or	a	liability	on	our	Balance	Sheets.	There	is	a	corresponding	non-cash	adjustment	to	accumulated	other	comprehensive	loss,	net	of	tax	benefits	recorded	as	deferred	tax assets,	in	stockholders'	equity.	The	GAAP	funded	status	represents	the	difference	between	the	fair	value	of	each	plan's	assets	and	the	benefit	obligation	of	the	plan.	The GAAP	benefit	obligation	represents	the	present	value	of	the	estimated	future	benefits	we	currently	expect	to	pay	to	plan	participants	based	on	past	service.

In	June	2014,	we	amended	certain	of	our	qualified	and	nonqualified	defined	benefit	pension	plans	for	non-union	employees	to	freeze	future	retirement	benefits.	The freeze	will	take	effect	in	two	stages.	Beginning	on	January	1,	2016,	the	pay-based	component	of	the	formula	used	to	determine	retirement	benefits	was	frozen	so	that future	pay	increases,	annual	incentive	bonuses	or	other	amounts	earned	for	or	related	to	periods	after	December	31,	2015	will	not	be	used	to	calculate	retirement benefits.	On	January	1,	2020,	the	service-based	component	of	the	formula	used	to	determine	retirement	benefits	will	also	be	frozen	so	that	participants	will	no	longer earn	further	credited	service	for	any	period	after	December	31,	2019.	When	the	freeze	is	complete,	the	majority	of	our	salaried	employees	will	have	transitioned	to	an enhanced	defined	contribution	retirement	savings	plan.

Notwithstanding	these	actions,	the	impact	of	these	plans	and	benefits	on	our	earnings	may	be	volatile	in	that	the	amount	of	expense	we	record	and	the	funded	status for	our	postretirement	benefit	plans	may	materially	change	from	year	to	year	because	those	calculations	are	sensitive	to	funding	levels	as	well	as	changes	in	several	key economic	assumptions,	including	interest	rates,	actual	rates	of	return	on	plan	assets	and	other	actuarial	assumptions	including	participant	longevity	and	employee turnover,	as	well	as	the	timing	of	cash	funding.

# Actuarial	Assumptions

The	plan	assets	and	benefit	obligations	are	measured	at	the	end	of	each	year	or	more	frequently,	upon	the	occurrence	of	certain	events	such	as	a	significant	plan amendment,	settlement	or	curtailment.	The	amounts	we	record	are	measured	using	actuarial	valuations,	which	are	dependent	upon	key	assumptions	such	as	discount rates,	employee	turnover,	participant	longevity,	the	expected	long-term	rate	of	return	on	plan	assets	and	the	health	care	cost	trend	rates	for	our	retiree	medical	plans.	The assumptions	we	make	affect	both	the	calculation	of	the	benefit	obligations	as	of	the	measurement	date	and	the	calculation	of	net	periodic	benefit	cost	in	subsequent periods.	When	reassessing	these	assumptions	we	consider	past	and	current	market	conditions	and	make	judgments	about	future	market	trends.	We	also	consider	factors such	as	the	timing	and	amounts	of	expected	contributions	to	the	plans	and	benefit	payments	to	plan	participants.

We	utilized	a	discount	rate	of	4.375%	when	calculating	our	benefit	obligations	related	to	our	defined	benefit	pension	plans	at	December	31,	2015,	compared	to 4.00%	at	December	31,	2014	and	4.75%	at	December	31,	2013.	We	utilized	a	discount	rate	of	4.25%	when	calculating	our	benefit	obligations	related	to	our	retiree medical	plans	at	December	31,	2015,	compared	to	3.75%	at	December	31,	2014	and	4.50%	at	December	31,	2013.	We	evaluate	several	data	points	in	order	to	arrive	at an	appropriate	discount	rate,	including	results	from	cash	flow	models,	quoted	rates	from	long-term	bond	indices	and	changes	in	long-term	bond	rates	over	the	past	year. As	part	of	our	evaluation,	we	calculate	the	approximate	average	yields	on	corporate	bonds	rated	AA	or	better	selected	to	match	our	projected	postretirement	benefit	plan cash	flows.

We	utilized	an	expected	 long-term	rate	of	return	on	plan	assets	of	8.00%	at	December	31,	2015,	consistent	with	 the	rate	used	at	December	31,	2014	and December	31,	2013.	The	long-term	rate	of	return	assumption	represents	the	expected	long-term	rate	of	return	on	the	funds	invested	or	to	be	invested,	to	provide	for	the benefits	included	in	the	benefit	obligations.	This	assumption	is	based	on	several	factors	including	historical	market	index	returns,	the	anticipated	long-term	allocation	of plan	assets,	the	historical	return	data	for	the	trust	funds,	plan	expenses	and	the	potential	to	outperform	market	index	returns.	The	difference	between	the	long-term	rate	of return	on	plan	assets	assumption	we	select	and	the	actual	return	on	plan	assets	in	any	given	year	affects	both	the	funded	status	of	our	benefit	plans	and	the	calculation	of FAS	pension	expense	in	subsequent	periods.	Although	the	actual	return	in	any	specific	year	likely	will	differ	from	the	assumption,	the	average	expected	return	over	a long-term	future	horizon	should	be	approximately	equal	to	the	assumption.	As	a	result,	changes	in	this	assumption	are	less	frequent	than	changes	in	the	discount	rate.

Our	stockholders'	equity	has	been	reduced	cumulatively	by	$11.3	billion	from	the	annual	year-end	measurements	of	the	funded	status	of	postretirement	benefit plans.	The	cumulative	non-cash,	after-tax	reduction	primarily	represents	net	actuarial	losses	resulting	from	declines	in	discount	rates	from	6.375%	at	the	end	of	2007	to 4.375%	at	the	end	of	2015	and	investment	losses	incurred	during	2008	and	2015,	which	will	be	amortized	to	expense	over	the	average	future	service	period	of	employees expected	to	receive	benefits	under	the	plans	of	approximately	10	years	as	of	December	31,	2015.	During	2015,	$850	million	of	these	amounts	was	recognized	as	a component	of	postretirement	benefit	plans	expense	and	about	$693	million	is	expected	to	be	recognized	as	expense	in	2016.

The	discount	rate	and	long-term	rate	of	return	on	plan	assets	assumptions	we	select	at	the	end	of	each	year	are	based	on	our	best	estimates	and	judgment.	A	change of	plus	or	minus	25	basis	points	in	the	4.375%	discount	rate	assumption	at	December	31,	2015,	with	all	other	assumptions	held	constant,	would	have	decreased	or increased	the	amount	of	the	qualified	pension	benefit	obligation	we	recorded	at	the	end	of	2015	by	approximately	$1.5	billion,	which	would	result	in	an	after-tax	increase or	decrease	in	stockholders'	equity	at	the	end	of	the	year	of	approximately	$1.0	billion.	If	the	4.375%	discount	rate	at	December	31,	2015	that	was	used	to	compute	the expected	2016	FAS	pension	expense	for	our	qualified	defined	benefit	pension	plans	had	been	25	basis	points	higher	or	lower,	with	all	other	assumptions	held	constant, the	amount	of	FAS	pension	expense	projected	for	2016	would	be	lower	or	higher	by	approximately	$120	million.	If	the	8.00%	expected	long-term	rate	of	return	on	plan assets	assumption	at	December	31,	2015	that	was	used	to	compute	the	expected	2016	FAS	pension	expense	for	our	qualified	defined	benefit	pension	plans	had	been	25 basis	 points	 higher	 or	 lower,	 with	 all	 other	 assumptions	 held	 constant,	 the	 amount	 of	 FAS	 pension	 expense	 projected	 for	 2016	 would	 be	 lower	 or	 higher	 by approximately	$85	million.

# Funding	Considerations

We	made	contributions	related	to	our	qualified	defined	benefit	pension	plans	of	$2.0	billion	in	2014	and	$2.25	billion	in	2013	inclusive	of	amounts	in	excess	of	our required	contributions.	We	made	$5	million	in	contributions	to	our	new	Sikorsky	bargained	qualified	defined	benefit	pension	plan	in	2015.	Funding	of	our	qualified defined	benefit	pension	plans	is	determined	in	a	manner	consistent	with	CAS	and	in	accordance	with	the	Employee	Retirement	Income	Security	Act	of	1974	(ERISA), as	amended	by	the	Pension	Protection	Act	of	2006	(PPA).	Our	goal	has	been	to	fund	the	pension	plans	to	a	level	of	at	least	80%,	as	determined	under	the	PPA.	This ERISA	funded	status	is	calculated	on	a	different	basis	than	under	GAAP.	In

July	2012,	the	U.S.	Government	passed	the	Moving	Ahead	for	Progress	in	the	21st	Century	Act	of	2012	(MAP-21),	which	included	a	provision	that	changed	the methodology	for	calculating	the	interest	rate	assumption	used	in	determining	the	minimum	funding	requirements	under	the	PPA.	As	a	result	of	MAP-21	there	was	an increase	in	the	interest	rate	assumption,	which	in	turn	lowered	the	minimum	funding	requirements.	The	impact	of	MAP-21	decreased	each	year	and	was	scheduled	to phase	out	by	2016.	On	August	8,	2014,	the	Highway	and	Transportation	Funding	Act	of	2014	(HATFA)	was	enacted;	and	on	November	2,	2015,	the	Bipartisan	Budget Act	of	2015;	which	extend	the	methodology	put	in	place	by	MAP-21	to	calculate	the	interest	rate	assumption	so	that	the	impact	will	begin	to	decrease	in	2021	and	phase out	by	2024.	This	has	the	effect	of	lowering	our	minimum	funding	requirements	during	the	affected	periods	from	what	they	otherwise	would	have	been	had	the legislation	not	been	enacted.	The	ERISA	funded	status	of	our	qualified	defined	benefit	pension	plans	was	about	90%	and	92%	as	of	December	31,	2015	and	2014.	The GAAP	funded	status	of	our	qualified	defined	benefit	pension	plans	was	about	73%	and	76%	funded	at	December	31,	2015	and	2014.

Contributions	to	our	defined	benefit	pension	plans	are	recovered	over	time	through	the	pricing	of	our	products	and	services	on	U.S.	Government	contracts,	including FMS,	and	are	recognized	in	our	cost	of	sales	and	net	sales.	CAS	govern	the	extent	to	which	our	pension	costs	are	allocable	to	and	recoverable	under	contracts	with	the U.S.	Government,	including	FMS.	We	recovered	$1.6	billion	in	2015	and	$1.5	billion	in	both	2014	and	2013	as	CAS	pension	costs.	Effective	February	27,	2012,	CAS rules	were	revised	to	better	align	the	recovery	of	pension	costs,	including	prepayment	credits,	on	U.S.	Government	contracts	with	the	minimum	funding	requirements	of the	PPA	(referred	to	as	CAS	Harmonization).	Specifically,	CAS	Harmonization	shortened	the	amortization	period	for	allocating	gains	and	losses	to	U.S.	Government contracts	from	15	to	10	years	and	requires	the	use	of	an	interest	rate	to	determine	CAS	pension	cost	consistent	with	the	interest	rate	used	to	determine	minimum	pension funding	requirements	under	the	PPA.	While	the	change	in	the	amortization	period	was	applicable	beginning	in	2013,	there	is	a	transition	period	for	the	impact	of	the change	in	the	CAS	liability	measurement	due	to	the	revised	interest	rate	that	will	be	phased	in	with	the	full	impact	occurring	in	2017.	We	expect	the	incremental	impact of	CAS	Harmonization	will	 increase	successively	 through	2017,	primarily	due	 to	 the	 liability	 measurement	 transition	 period	 included	 in	 the	 amended	 rule.	The enactment	of	the	HATFA	and	Bipartisan	Budget	Act	of	2015	also	increased	the	interest	rate	assumption	used	to	determine	our	CAS	pension	costs,	which	has	the	effect of	lowering	the	recovery	of	pension	contributions	during	the	affected	periods	as	it	decreases	our	CAS	pension	costs.

Pension	cost	recoveries	under	CAS	occur	in	different	periods	from	when	pension	contributions	are	made	under	the	PPA.	Amounts	contributed	in	excess	of	the	CAS pension	costs	recovered	under	U.S.	Government	contracts	are	considered	to	be	prepayment	credits	under	the	CAS	rules.	As	of	December	31,	2015,	our	prepayment credits	were	approximately	$9.0	billion	as	compared	to	$10.8	billion	at	December	31,	2014.	The	prepayment	balance	will	increase	or	decrease	based	on	our	actual investment	return	on	plan	assets.

We	do	not	plan	to	make	contributions	to	our	heritage	pension	plans	in	2016	or	2017	because	none	are	required	using	current	assumptions,	including	anticipated investment	returns	on	plan	assets.	However,	we	do	plan	to	make	contributions	of	approximately	$25	million	in	2016	and	about	$35	million	in	2017	to	our	new	Sikorsky bargained	qualified	defined	benefit	pension	plan.	We	anticipate	recovering	approximately	$2.0	billion	of	CAS	pension	cost	in	2016	with	a	higher	CAS	recovery projected	in	2017.	Since	the	annual	amount	of	CAS	cost	is	more	than	our	planned	cash	funding	in	each	of	these	years,	we	will	recover	a	portion	of	the	$9.0	billion	of prepayment	credits	existing	at	December	31,	2015.

We	expect	our	2016	FAS	pension	expense	to	be	$1.0	billion,	which	is	comparable	to	our	2015	FAS	pension	expense	of	$1.1	billion.	Also,	we	expect	FAS/CAS pension	income	in	2016	of	about	$975	million,	as	compared	to	FAS/CAS	pension	income	of	$471	million	in	2015,	primarily	due	to	higher	CAS	pension	costs	due	to CAS	Harmonization.

# Environmental	Matters

We	are	a	party	to	various	agreements,	proceedings	and	potential	proceedings	for	environmental	cleanup	issues,	including	matters	at	various	sites	where	we	have been	designated	a	potentially	responsible	party	(PRP).	At	December	31,	2015	and	2014,	the	total	amount	of	liabilities	recorded	on	our	Balance	Sheet	for	environmental matters	was	$1.0	billion	and	$965	million.	We	have	recorded	receivables	totaling	$858	million	and	$836	million	at	December	31,	2015	and	2014	for	the	portion	of environmental	costs	that	are	probable	of	future	recovery	in	pricing	of	our	products	and	services	for	agencies	of	the	U.S.	Government,	as	discussed	below.	The	amount that	is	expected	to	be	allocated	to	our	non-U.S.	Government	contracts	or	that	is	determined	to	not	be	recoverable	under	U.S.	Government	contracts	has	been	expensed through	cost	of	sales.	We	project	costs	and	recovery	of	costs	over	approximately	20	years.	Our	acquisition	of	Sikorsky	included	certain	environmental	remediation liabilities	that	are	among	those	recorded	on	our	Balance	Sheet,	along	with	the	related	receivables	for	probable	future	recovery.	These	amounts	did	not	materially	impact our	consolidated	financial	statements.

We	enter	into	agreements	(e.g.,	administrative	orders,	consent	decrees)	that	document	the	extent	and	timing	of	our	environmental	remediation	obligation.	We	also are	involved	in	remediation	activities	at	environmental	sites	where	formal	agreements	either	do	not	exist	or	do	not	quantify	the	extent	and	timing	of	our	obligation. Environmental	cleanup	activities	usually	span	many	years,	which	makes	estimating	the	costs	more	judgmental	due	to,	for	example,	changing	remediation	technologies. To	determine	the	costs	related	to	cleanup	sites,	we	have	to	assess	the	extent	of	contamination,	effects	on	natural	resources,	the	appropriate	technology	to	be	used	to accomplish	the	remediation	and	evolving	governmental	environmental	standards.

We	perform	quarterly	reviews	of	environmental	remediation	sites	and	record	liabilities	and	receivables	in	the	period	it	becomes	probable	that	a	liability	has	been incurred	and	the	amounts	can	be	reasonably	estimated	(see	the	discussion	under	"Environmental	Matters"	in	"Note	1	–	Significant	Accounting	Policies"	and	"Note	14	– Legal	Proceedings,	Commitments	and	Contingencies"	to	our	consolidated	financial	statements).	We	consider	the	above	factors	in	our	quarterly	estimates	of	the	timing and	amount	of	any	future	costs	that	may	be	required	for	remediation	activities,	which	results	in	the	calculation	of	a	range	of	estimates	for	a	particular	environmental	site. We	do	not	discount	the	recorded	liabilities,	as	the	amount	and	timing	of	future	cash	payments	are	not	fixed	or	cannot	be	reliably	determined.	Given	the	required	level	of judgment	and	estimation,	it	is	likely	that	materially	different	amounts	could	be	recorded	if	different	assumptions	were	used	or	if	circumstances	were	to	change	(e.g.,	a change	in	environmental	standards	or	a	change	in	our	estimate	of	the	extent	of	contamination).

On	July	1,	2014,	a	regulation	became	effective	in	California	setting	the	maximum	level	of	the	contaminant	hexavalent	chromium	in	drinking	water	at	10	parts	per billion	(ppb).	In	May	2014,	the	California	Manufacturers	and	Technology	Association	filed	a	suit	alleging	the	10	ppb	threshold	is	lower	than	is	required	to	protect	public health	and	thus	imposes	unjustified	costs	on	the	regulated	community.	We	cannot	predict	the	outcome	of	this	suit	or	whether	other	challenges	may	be	advanced	by	the regulated	community	or	environmental	groups	which	had	sought	a	significantly	higher	and	lower	standard,	respectively.	If	the	new	standard	remains	at	10	ppb,	it	will	not have	a	material	impact	on	our	existing	remediation	costs	in	California.	In	addition,	California	is	reevaluating	its	existing	drinking	water	standard	with	respect	to	a	second contaminant,	perchlorate,	and	the	U.S.	Environmental	Protection	Agency	(U.S.	EPA)	is	also	considering	whether	to	regulate	perchlorate	and	hexavalent	chromium	in drinking	water.	In	February	2016,	the	Natural	Resources	Defense	Council	filed	suit	in	federal	court	in	New	York	against	the	U.S.	EPA	to	compel	the	U.S.	EPA	to	set	an enforceable	drinking	water	standard	for	perchlorate.	If	substantially	lower	standards	are	adopted,	in	either	California	or	at	the	federal	level,	for	perchlorate	or,	if	the	U.S. EPA	were	to	adopt	a	standard	for	hexavalent	chromium	lower	than	10	ppb,	we	expect	a	material	increase	in	our	estimates	for	environmental	liabilities	and	the	related assets	for	the	portion	of	the	increased	costs	that	are	probable	of	future	recovery	in	the	pricing	of	our	products	and	services	for	the	U.S.	Government.	The	amount	that would	be	allocable	to	our	non-U.S.	Government	contracts	or	that	is	determined	to	not	be	recoverable	under	U.S.	Government	contracts	would	be	expensed,	which	may have	a	material	effect	on	our	earnings	in	any	particular	interim	reporting	period.

Under	agreements	reached	with	the	U.S.	Government,	most	of	the	amounts	we	spend	for	environmental	remediation	are	allocated	to	our	operations	as	general	and administrative	costs.	Under	existing	government	regulations,	these	and	other	environmental	expenditures	relating	to	our	U.S.	Government	business,	after	deducting	any recoveries	received	from	insurance	or	other	PRPs,	are	allowable	in	establishing	prices	of	our	products	and	services.	As	a	result,	most	of	the	expenditures	we	incur	are included	in	our	net	sales	and	cost	of	sales	according	to	U.S.	Government	agreement	or	regulation,	regardless	of	the	contract	form	(e.g.	cost-reimbursable,	fixed-price). We	continually	evaluate	the	recoverability	of	our	environmental	receivables	by	assessing,	among	other	factors,	U.S.	Government	regulations,	our	U.S.	Government business	base	and	contract	mix	and	our	history	of	receiving	reimbursement	of	such	costs.

As	disclosed	above,	we	may	record	changes	in	the	amount	of	environmental	remediation	liabilities	as	a	result	of	our	quarterly	reviews	of	the	status	of	our environmental	remediation	sites,	which	would	result	in	a	change	to	the	corresponding	environmental	receivable	and	a	charge	to	earnings.	For	example,	if	we	were	to determine	that	the	liabilities	should	be	increased	by	$100	million,	the	corresponding	receivables	would	be	increased	by	approximately	$87	million,	with	the	remainder recorded	as	a	charge	to	earnings.	This	allocation	is	determined	annually,	based	upon	our	existing	and	projected	business	activities	with	the	U.S.	Government.

We	reasonably	cannot	determine	the	extent	of	our	financial	exposure	at	all	environmental	sites	with	which	we	are	involved.	There	are	a	number	of	former	operating facilities	we	are	monitoring	or	investigating	for	potential	future	remediation.	In	some	cases,	although	a	loss	may	be	probable,	it	is	not	possible	at	this	time	to	reasonably estimate	the	amount	of	any	obligation	for	remediation	activities	because	of	uncertainties	(e.g.,	assessing	the	extent	of	the	contamination).	During	any	particular	quarter, such	uncertainties	may	be	resolved,	allowing	us	to	estimate	and	recognize	the	initial	liability	to	remediate	a	particular	former	operating	site.	The	amount	of	the	liability could	be	material.	Upon	recognition	of	the	liability,	a	portion	will	be	recognized	as	a	receivable	with	the	remainder	charged	to	earnings	which	may	have	a	material	effect in	any	particular	interim	reporting	period.

If	we	are	ultimately	found	to	have	liability	at	those	sites	where	we	have	been	designated	a	PRP,	we	expect	that	the	actual	costs	of	remediation	will	be	shared	with other	liable	PRPs.	Generally,	PRPs	that	are	ultimately	determined	to	be	responsible	parties	are	strictly	liable	for	site	cleanup	and	usually	agree	among	themselves	to share,	on	an	allocated	basis,	the	costs	and	expenses	for	investigation	and	remediation.	Under	existing	environmental	laws,	responsible	parties	are	jointly	and	severally liable	and,	therefore,	we	are	potentially	liable	for	the	full	cost	of	funding	such	remediation.	In	the	unlikely	event	that	we	were	required	to	fund	the	entire	cost	of	such remediation,	the	statutory	framework	provides	that	we	may	pursue	rights	of	cost	recovery	or	contribution	from	the	other	PRPs.	The	amounts	we	record	do	not	reflect	the fact	that	we	may	recover	some	of	the	environmental	costs	we	have	incurred	through	insurance	or	from	other	PRPs,	which	we	are	required	to	pursue	by	agreement	and U.S.	Government	regulation.

# Goodwill

The	assets	and	liabilities	of	acquired	businesses	are	recorded	under	the	acquisition	method	of	accounting	at	their	estimated	fair	values	at	the	date	of	acquisition. Goodwill	represents	costs	in	excess	of	fair	values	assigned	to	the	underlying	identifiable	net	assets	of	acquired	businesses.

Our	goodwill	balances	were	$13.6	billion	and	$10.9	billion	at	December	31,	2015	and	2014.	During	2015,	our	goodwill	balance	increased	$2.7	billion,	primarily	as a	result	of	$2.8	billion	in	preliminary	goodwill	recorded	in	connection	with	the	Sikorsky	acquisition.	We	perform	an	impairment	test	of	our	goodwill	at	least	annually	in the	fourth	quarter	or	more	frequently	whenever	events	or	changes	in	circumstances	indicate	the	carrying	value	of	goodwill	may	be	impaired.	Such	events	or	changes	in circumstances	 may	 include	 a	 significant	 deterioration	 in	 overall	 economic	 conditions,	 changes	 in	 the	 business	 climate	 of	 our	 industry,	 a	 decline	 in	 our	 market capitalization,	operating	performance	indicators,	competition,	reorganizations	of	our	business,	U.S.	Government	budget	restrictions	or	the	disposal	of	all	or	a	portion	of	a reporting	unit.	Our	goodwill	has	been	allocated	to	and	is	tested	for	impairment	at	a	level	referred	to	as	the	reporting	unit,	which	is	our	business	segment	level	or	a	level below	the	business	segment.	The	level	at	which	we	test	goodwill	for	impairment	requires	us	to	determine	whether	the	operations	below	the	business	segment	constitute	a self-sustaining	business	for	which	discrete	financial	information	is	available	and	segment	management	regularly	reviews	the	operating	results.

We	may	use	both	qualitative	and	quantitative	approaches	when	testing	goodwill	for	impairment.	Under	the	qualitative	approach	for	selected	reporting	units	we perform	a	qualitative	evaluation	of	events	and	circumstances	impacting	the	reporting	unit	to	determine	the	likelihood	of	goodwill	impairment.	Based	on	that	qualitative evaluation,	if	we	determine	it	is	more	likely	than	not	that	the	fair	value	of	a	reporting	unit	exceeds	its	carrying	amount,	no	further	evaluation	is	necessary.	Otherwise	we perform	a	quantitative	two-step	impairment	test.	For	certain	reporting	units	we	only	perform	a	quantitative	impairment	test.

Under	step	one	of	the	quantitative	two	step	impairment	test,	we	compare	the	fair	value	of	a	reporting	unit	to	its	carrying	value,	including	goodwill.	If	the	fair	value of	a	reporting	unit	exceeds	its	carrying	value,	goodwill	of	the	reporting	unit	is	not	impaired.	If	the	carrying	value	of	a	reporting	unit	exceeds	its	fair	value,	we	then perform	step	two	of	the	quantitative	impairment	test	and	compare	the	implied	value	of	the	reporting	unit's	goodwill	with	the	carrying	value	of	its	goodwill.	The	implied value	of	the	reporting	unit's	goodwill	is	calculated	by	creating	a	hypothetical	balance	sheet	as	if	the	reporting	unit	had	just	been	acquired.	This	balance	sheet	contains	all assets	and	liabilities	recorded	at	fair	value	(including	any	assumed	intangible	assets	that	may	not	have	any	corresponding	carrying	value	in	our	balance	sheet).	The implied	value	of	the	reporting	unit's	goodwill	is	calculated	by	subtracting	the	fair	value	of	the	net	assets	from	the	fair	value	of	the	reporting	unit.	If	the	carrying	value	of the	reporting	unit's	goodwill	exceeds	the	implied	value	of	that	goodwill,	an	impairment	loss	is	recognized	in	an	amount	equal	to	that	excess.

We	estimate	the	fair	value	of	each	reporting	unit	using	a	combination	of	a	discounted	cash	flow	(DCF)	analysis	and	market-based	valuation	methodologies	such	as comparable	public	company	trading	values	and	values	observed	in	recent	business	acquisitions.	Determining	fair	value	requires	the	exercise	of	significant	judgments, including	the	amount	and	timing	of	expected	future	cash	flows,	long-term	growth	rates,	discount	rates	and	relevant	comparable	public	company	earnings	multiples	and relevant	transaction	multiples.	The	cash	flows	employed	in	the	DCF	analyses	are	based	on	our	best	estimate	of	future	sales,	earnings	and	cash	flows	after	considering factors	such	as	general	market	conditions,	U.S.	Government	budgets,	existing	firm	orders,	expected	future	orders,	contracts	with	suppliers,	labor	agreements,	changes	in working	capital,	long	term	business	plans	and	recent	operating	performance.	The	discount	rates	utilized	in	the	DCF	analysis	are	based	on	the	respective	reporting	unit's weighted	average	cost	of	capital,	which	takes	into	account	the	relative	weights	of	each	component	of	capital	structure	(equity	and	debt)	and	represents	the	expected	cost of	new	capital,	adjusted	as	appropriate	to	consider	the	risk	inherent	in	future	cash	flows	of	the	respective	reporting	unit.

The	carrying	value	of	each	reporting	unit	includes	the	assets	and	liabilities	employed	in	its	operations,	goodwill	and	allocations	of	amounts	held	at	the	business segment	and	corporate	levels.	Corporate	allocations	include	our	postretirement	benefit	plans	liabilities,	as	determined	in	accordance	with	CAS,	in	order	to	align	the	basis of	the	carrying	values	with	the	determination	of	the	fair	values	of	our	reporting	units,	which	are	measured	using	CAS	pension	cost.	CAS	pension	cost	is	recovered through	the	pricing	of	our	products	and	services	on	U.S.	Government	contracts	and,	therefore,	affects	the	fair	value	of	each	reporting	unit.	The	amount	of	CAS	pension liability	allocated	to	each	reporting	unit	is	significantly	influenced	by	a	number	of	factors,	including	the	discount	rate	used	to	estimate	the	obligation.	On	August	8,	2014, the	HATFA,	and	on	November	2,	2015,	the	Bipartisan	Budget	Act	of	2015	was	enacted,	which	extended	the	pension	interest	rate	relief	of	the	prior	MAP-21.	As	a	result, the	interest	rate	used	to	calculate	CAS	pension	costs	recovered	under	our	contracts	with	the	U.S.	Government	increased	with	the	resulting	effect	of	decreasing	the amount	of	CAS	pension	liability	allocated	to	each	reporting	unit,	contributing	to	an	increase	in	the	carrying	value	of	each	reporting	unit.

In	the	fourth	quarter	of	2015,	we	performed	our	annual	goodwill	impairment	test	for	each	of	our	reporting	units.	In	connection	with	our	fourth	quarter	2015	program realignment,	goodwill	was	reallocated	between	affected	reporting	units	on	a	relative	fair	value	basis.	We	performed	goodwill	impairment	tests	prior	and	subsequent	to	the realignment.	The	results	of	our	2015	annual	impairment	tests	of	goodwill	indicated	that	no	impairment	existed.

In	the	fourth	quarter	of	2014,	we	performed	our	annual	goodwill	impairment	test	for	each	of	our	reporting	units.	The	results	of	these	tests	indicated	that	the estimated	fair	values	of	our	reporting	units	exceeded	their	carrying	values,	with	the	exception	of	our	Technical	Services	reporting	unit	within	our	IS&GS	business segment.	Technical	Services,	for	which	we	recorded	a	$195	million	goodwill	impairment	in	2013,	experienced	further	declines	in	fair	value	during	2014.	Technical Services	which	typically	has	smaller	customer	contracts	of	a	shorter	duration,	has	been	adversely	impacted	by	market	pressures	such	as	lower	in-theater	support	as	troop levels	are	drawn	down	and	increased	re-competition	on	existing	contracts	that	are	awarded	primarily	on	the	basis	of	price.	As	a	result,	we	compared	the	implied	value	of that	reporting	unit's	goodwill	with	the	carrying	value	of	its	goodwill,	and	since	the	carrying	value	exceeded	the	implied	value,	we	recorded	a	non-cash	impairment charge	of	$119	million	in	the	fourth	quarter	of	2014	equal	to	that	differential.

As	a	result	of	the	2014	annual	goodwill	impairment	test,	our	Civil	reporting	unit	was	considered	at	risk	of	future	goodwill	impairment	due	to	market	factors	and because	the	fair	value	of	the	Civil	reporting	unit	exceeded	its	carrying	value	by	a	margin	of	approximately	15%.	The	results	of	our	2015	annual	goodwill	impairment	test indicated	that	our	Civil	reporting	unit's	fair	value	was	no	longer	considered	at	risk	of	future	goodwill	impairment	due	to	an	increase	in	assessed	fair	value.

Impairment	assessments	inherently	involve	management	judgments	regarding	a	number	of	assumptions	such	as	those	described	above.	Due	to	the	many	variables inherent	in	the	estimation	of	a	reporting	unit's	fair	value	and	the	relative	size	of	our	recorded	goodwill,	differences	in	assumptions	could	have	a	material	effect	on	the estimated	fair	value	of	one	or	more	of	our	reporting	units	and	could	result	in	a	goodwill	impairment	charge	in	a	future	period.

# Intangible	Assets

Intangible	assets	from	acquired	businesses	are	recognized	at	their	estimated	fair	values	at	the	date	of	acquisition	and	consist	of	customer	programs,	trademarks, customer	relationships,	technology	and	other	intangible	assets.	Customer	programs	include	values	assigned	to	major	programs	of	acquired	businesses	and	represent	the aggregate	value	associated	with	the	customer	relationships,	contracts,	technology	and	trademarks	underlying	the	associated	program.	Acquired	intangibles	deemed	to have	indefinite	lives	are	not	amortized,	but	are	subject	to	annual	impairment	testing.	This	testing	compares	carrying	value	to	fair	value	and,	when	appropriate,	the carrying	value	of	these	assets	is	reduced	to	fair	value.	Finite-lived	intangibles	are	amortized	to	expense	over	the	applicable	useful	lives,	ranging	from	three	to	twenty years,	based	on	the	nature	of	the	asset	and	the	underlying	pattern	of	economic	benefit	as	reflected	by	future	net	cash	inflows.

# Recent	Accounting	Pronouncements

In	May	2014,	the	Financial	Accounting	Standards	Board	(FASB)	issued	a	new	standard	that	will	change	the	way	we	recognize	revenue	and	significantly	expand	the disclosure	requirements	for	revenue	arrangements.	On	July	9,	2015,	the	FASB	approved	a	one-year	deferral	of	the	effective	date	of	the	standard	to	2018	for	public companies,	with	an	option	that	would	permit	companies	to	adopt	the	standard	in	2017.	Early	adoption	prior	to	2017	is	not	permitted.	The	new	standard	may	be	adopted either	 retrospectively	 or	 on	 a	 modified	 retrospective	 basis	 whereby	 the	 new	 standard	 would	 be	 applied	 to	 new	 contracts	 and	 existing	 contracts	 with	 remaining performance	obligations	as	of	the	effective	date,	with	a	cumulative	catch-up	adjustment	recorded	to	beginning	retained	earnings	at	the	effective	date	for	existing contracts	with	remaining	performance

obligations.	In	addition,	the	FASB	is	contemplating	making	additional	changes	to	certain	elements	of	the	new	standard.	We	are	currently	evaluating	the	methods	of adoption	allowed	by	the	new	standard	and	the	effect	the	standard	is	expected	to	have	on	our	consolidated	financial	statements	and	related	disclosures.	As	the	new standard	will	supersede	substantially	all	existing	revenue	guidance	affecting	us	under	GAAP,	it	could	impact	revenue	and	cost	recognition	on	thousands	of	contracts across	all	our	business	segments,	in	addition	to	our	business	processes	and	our	information	technology	systems.	As	a	result,	our	evaluation	of	the	effect	of	the	new standard	will	extend	over	future	periods.

In	September	2015,	 the	FASB	 issued	a	new	standard	 that	simplifies	 the	accounting	for	adjustments	made	 to	preliminary	amounts	recognized	 in	a	business combination	by	eliminating	 the	requirement	 to	retrospectively	account	for	 those	adjustments.	Instead,	adjustments	will	be	recognized	 in	 the	period	 in	which	 the adjustments	are	determined,	including	the	effect	on	earnings	of	any	amounts	that	would	have	been	recorded	in	previous	periods	if	the	accounting	had	been	completed	at the	acquisition	date.	We	adopted	the	standard	on	January	1,	2016	and	will	prospectively	apply	the	standard	to	business	combination	adjustments	identified	after	the	date of	adoption.

In	November	2015,	the	FASB	issued	a	new	standard	that	simplifies	the	presentation	of	deferred	income	taxes	and	requires	that	deferred	tax	assets	and	liabilities,	as well	as	any	related	valuation	allowance,	be	classified	as	noncurrent	in	our	consolidated	balance	sheets.	The	standard	is	effective	January	1,	2017,	with	early	adoption permitted.	The	standard	may	be	applied	either	prospectively	from	the	date	of	adoption	or	retrospectively	to	all	prior	periods	presented.	We	are	currently	evaluating	when we	will	adopt	the	standard	and	the	method	of	adoption.

# ITEM	7A. Quantitative	and	Qualitative	Disclosures	About	Market	Risk.

We	maintain	active	relationships	with	a	broad	and	diverse	group	of	U.S.	and	international	financial	institutions.	We	believe	that	they	provide	us	with	sufficient access	to	the	general	and	trade	credit	we	require	to	conduct	our	business.	We	continue	to	closely	monitor	the	financial	market	environment	and	actively	manage counterparty	exposure	to	minimize	the	potential	impact	from	adverse	developments	with	any	single	credit	provider	while	ensuring	availability	of,	and	access	to, sufficient	credit	resources.

Our	main	exposure	to	market	risk	relates	to	interest	rates,	foreign	currency	exchange	rates	and	market	prices	on	certain	equity	securities.	Our	financial	instruments that	are	subject	to	interest	rate	risk	principally	include	fixed-rate	long-term	debt.	The	estimated	fair	value	of	our	outstanding	debt	was	$16.5	billion	at	December	31, 2015	and	the	outstanding	principal	amount	was	$16.2	billion,	excluding	unamortized	discounts	and	deferred	financing	costs	of	$1.0	billion.	A	10%	change	in	the	level	of interest	rates	would	not	have	a	material	impact	on	the	fair	value	of	our	outstanding	debt	at	December	31,	2015.

We	use	derivative	instruments	principally	to	reduce	our	exposure	to	market	risks	from	changes	in	foreign	currency	exchange	rates	and	interest	rates.	We	do	not enter	into	or	hold	derivative	instruments	for	speculative	trading	purposes.	We	transact	business	globally	and	are	subject	to	risks	associated	with	changing	foreign currency	exchange	rates.	We	enter	into	foreign	currency	hedges	such	as	forward	and	option	contracts	that	change	in	value	as	foreign	currency	exchange	rates	change.	Our most	significant	foreign	currency	exposures	relate	to	the	British	Pound	Sterling	and	the	Canadian	Dollar.	These	contracts	hedge	forecasted	foreign	currency	transactions in	order	to	mitigate	fluctuations	in	our	earnings	and	cash	flows	associated	with	changes	in	foreign	currency	exchange	rates.	We	designate	foreign	currency	hedges	as cash	flow	hedges.	We	also	are	exposed	to	the	impact	of	interest	rate	changes	primarily	through	our	borrowing	activities.	For	fixed	rate	borrowings,	we	may	use	variable interest	rate	swaps,	effectively	converting	fixed	rate	borrowings	to	variable	rate	borrowings	indexed	to	LIBOR	in	order	to	reduce	the	amount	of	interest	paid.	These swaps	are	designated	as	fair	value	hedges.	For	variable	rate	borrowings,	we	may	use	fixed	interest	rate	swaps,	effectively	converting	variable	rate	borrowings	to	fixed rate	borrowings	in	order	to	mitigate	the	impact	of	interest	rate	changes	on	earnings.	These	swaps	are	designated	as	cash	flow	hedges.	We	also	may	enter	into	derivative instruments	that	are	not	designated	as	hedges	and	do	not	qualify	for	hedge	accounting,	which	are	intended	to	mitigate	certain	economic	exposures.

The	classification	of	gains	and	losses	resulting	from	changes	in	the	fair	values	of	derivatives	is	dependent	on	our	intended	use	of	the	derivative	and	its	resulting designation.	Adjustments	to	reflect	changes	in	fair	values	of	derivatives	attributable	to	the	effective	portion	of	hedges	are	either	reflected	in	earnings	and	largely	offset	by corresponding	adjustments	to	the	hedged	items	or	reflected	net	of	income	taxes	in	accumulated	other	comprehensive	loss	until	the	hedged	transaction	is	recognized	in earnings.	Changes	in	the	fair	value	of	the	derivatives	that	are	attributable	to	the	ineffective	portion	of	the	hedges,	or	of	derivatives	that	are	not	considered	to	be	highly effective	hedges,	if	any,	are	immediately	recognized	in	earnings.	The	aggregate	notional	amount	of	our	outstanding	interest	rate	swaps	at	December	31,	2015	and	2014 was	$1.5	billion	and	$1.3	billion.	The	aggregate	notional	amount	of	our	outstanding	foreign	currency	hedges	at	December	31,	2015	and	2014	was	$4.1	billion	and	$804 million.	At	December	31,	2015	and	2014,	the	net	fair	value	of	our	derivative	instruments	was	not

material	(Note	15).	A	10%	appreciation	or	devaluation	of	the	hedged	currency	as	compared	to	the	level	of	foreign	exchange	rates	for	currencies	under	contract	at December	31,	2015	would	not	have	a	material	impact	on	the	aggregate	net	fair	value	of	such	contracts	or	our	consolidated	financial	statements.

We	evaluate	the	credit	quality	of	potential	counterparties	to	derivative	transactions	and	only	enter	into	agreements	with	those	deemed	to	have	acceptable	credit	risk at	 the	 time	 the	agreements	are	executed.	Our	foreign	currency	exchange	hedge	portfolio	 is	diversified	across	several	banks.	We	periodically	monitor	changes	 to counterparty	credit	quality	as	well	as	our	concentration	of	credit	exposure	to	individual	counterparties.	We	do	not	hold	or	issue	derivative	financial	instruments	for trading	or	speculative	purposes.

We	maintain	a	separate	trust	that	includes	investments	to	fund	certain	of	our	non-qualified	deferred	compensation	plans.	As	of	December	31,	2015,	investments	in the	trust	totaled	$1.1	billion	and	are	reflected	at	fair	value	on	our	Balance	Sheet	in	other	noncurrent	assets.	The	trust	holds	investments	in	marketable	equity	securities and	fixed-income	securities	that	are	exposed	to	price	changes	and	changes	in	interest	rates.	A	portion	of	the	liabilities	associated	with	the	deferred	compensation	plans supported	by	the	trust	is	also	impacted	by	changes	in	the	market	price	of	our	common	stock	and	certain	market	indices.	Changes	in	the	value	of	the	liabilities	have	the effect	of	partially	offsetting	the	impact	of	changes	in	the	value	of	the	trust.	Both	the	change	in	the	fair	value	of	the	trust	and	the	change	in	the	value	of	the	liabilities	are recognized	on	our	Statements	of	Earnings	in	other	unallocated,	net	and	were	not	material	for	the	year	ended	December	31,	2015.

# ITEM	8. Financial	Statements	and	Supplementary	Data.

# Report	of	Ernst	&	Young	LLP,

# Independent	Registered	Public	Accounting	Firm,

# on	the	Audited	Consolidated	Financial	Statements

# Board	of	Directors	and	Stockholders

We	have	audited	the	accompanying	consolidated	balance	sheets	of	Lockheed	Martin	Corporation	as	of	December	31,	2015	and	2014,	and	the	related	consolidated statements	of	earnings,	comprehensive	income,	stockholders'	equity,	and	cash	flows	for	each	of	the	three	years	in	the	period	ended	December	31,	2015.	These	financial statements	are	the	responsibility	of	the	Corporation's	management.	Our	responsibility	is	to	express	an	opinion	on	these	financial	statements	based	on	our	audits.

We	conducted	our	audits	in	accordance	with	the	standards	of	the	Public	Company	Accounting	Oversight	Board	(United	States).	Those	standards	require	that	we plan	and	perform	the	audit	to	obtain	reasonable	assurance	about	whether	the	financial	statements	are	free	of	material	misstatement.	An	audit	includes	examining,	on	a test	basis,	evidence	supporting	the	amounts	and	disclosures	in	the	financial	statements.	An	audit	also	includes	assessing	the	accounting	principles	used	and	significant estimates	made	by	management,	as	well	as	evaluating	the	overall	financial	statement	presentation.	We	believe	that	our	audits	provide	a	reasonable	basis	for	our	opinion.

In	our	opinion,	the	financial	statements	referred	to	above	present	fairly,	in	all	material	respects,	the	consolidated	financial	position	of	Lockheed	Martin	Corporation at	December	31,	2015	and	2014,	and	the	consolidated	results	of	its	operations	and	its	cash	flows	for	each	of	the	three	years	in	the	period	ended	December	31,	2015,	in conformity	with	U.S.	generally	accepted	accounting	principles.

We	also	have	audited,	in	accordance	with	the	standards	of	the	Public	Company	Accounting	Oversight	Board	(United	States),	Lockheed	Martin	Corporation's internal	control	over	financial	reporting	as	of	December	31,	2015,	based	on	criteria	established	in	Internal	Control	–	Integrated	Framework	issued	by	the	Committee	of Sponsoring	Organizations	of	the	Treadway	Commission	(2013	framework)	and	our	report	dated	February	24,	2016	expressed	an	unqualified	opinion	thereon.

# Notes	to	Consolidated	Financial	Statements

# Note	1	–	Significant	Accounting	Policies

Organization	 –	 We	 are	 a	 global	 security	 and	 aerospace	 company	 principally	 engaged	 in	 the	 research,	 design,	 development,	 manufacture,	 integration	 and sustainment	of	advanced	technology	systems,	products	and	services.	We	also	provide	a	broad	range	of	management,	engineering,	technical,	scientific,	logistics	and information	services.	We	serve	both	U.S.	and	international	customers	with	products	and	services	that	have	defense,	civil	and	commercial	applications,	with	our	principal customers	being	agencies	of	the	U.S.	Government.

Basis	of	presentation	–	Our	consolidated	financial	statements	include	the	accounts	of	subsidiaries	we	control	and	variable	interest	entities	if	we	are	the	primary beneficiary.	We	eliminate	intercompany	balances	and	transactions	in	consolidation.	Our	receivables,	inventories,	customer	advances	and	amounts	in	excess	of	costs incurred	and	certain	amounts	in	other	current	liabilities	primarily	are	attributable	to	long-term	contracts	or	programs	in	progress	for	which	the	related	operating	cycles are	longer	than	one	year.	In	accordance	with	industry	practice,	we	include	these	items	in	current	assets	and	current	liabilities.	Unless	otherwise	noted,	we	present	all	per share	amounts	cited	in	these	consolidated	financial	statements	on	a	"per	diluted	share"	basis.	Certain	prior	period	amounts	have	been	reclassified	to	conform	with	current year	presentation.

On	November	6,	2015,	we	completed	the	acquisition	of	Sikorsky	Aircraft	Corporation	(Sikorsky)	for	$9.0	billion,	net	of	cash	acquired.	Sikorsky,	a	global	company primarily	engaged	in	the	design,	manufacture,	service	and	support	of	military	and	commercial	helicopters,	has	become	a	wholly-owned	subsidiary	of	ours,	aligned	under our	MST	business	segment.	The	financial	results	of	the	acquired	Sikorsky	business	have	been	included	in	our	consolidated	results	of	operations	from	the	November	6, 2015	acquisition	date	through	December	31,	2015.	Accordingly,	the	consolidated	financial	results	for	the	year	ended	December	31,	2015	do	not	reflect	a	full	year	of Sikorsky	operations.

During	the	fourth	quarter	of	2015,	we	realigned	certain	programs	between	our	business	segments	in	connection	with	the	strategic	review	of	our	government informational	technology	(IT)	and	technical	services	businesses.	The	amounts,	discussion	and	presentation	of	our	business	segments	as	set	forth	in	all	years	presented	in our	consolidated	financial	statements	have	been	reclassified	from	prior	year	presentation	to	reflect	the	realignment.	The	realignment	did	not	impact	the	Corporation's previously	reported	consolidated	financial	statements.	See	"Note	5	–	Information	on	Business	Segments"	for	additional	information	including	revised	historical	segment results	under	our	new	structure.

On	January	26,	2016	we	entered	into	definitive	agreements	to	separate	and	combine	our	Information	Systems	&	Global	Solutions	(IS&GS)	business	segment	with Leidos	Holdings,	Inc.	(Leidos)	in	a	tax-efficient	Reverse	Morris	Trust	transaction.	Subsequent	to	the	program	realignment	described	above,	our	IS&GS	business segment	represents	the	government	IT	and	technical	services	businesses	that	were	under	strategic	review.	The	transaction	is	expected	to	close	in	the	third	or	fourth quarter	of	2016.	Until	closing,	IS&GS	will	operate	as	a	business	segment	and	financial	results	for	the	IS&GS	business	segment	will	be	reported	in	our	continuing operations.	See	"Note	3	–	Acquisitions	and	Divestitures"	for	additional	information	about	the	planned	divestiture	of	our	IS&GS	business	segment.

Use	of	estimates	–	We	prepare	our	consolidated	financial	statements	in	conformity	with	U.S.	generally	accepted	accounting	principles	(GAAP).	In	doing	so,	we	are required	to	make	estimates	and	assumptions	that	affect	the	amounts	reported	in	the	consolidated	financial	statements	and	accompanying	notes.	We	base	these	estimates on	historical	experience	and	on	various	other	assumptions	that	we	believe	are	reasonable	under	the	circumstances,	the	results	of	which	form	the	basis	for	making judgments	about	the	carrying	amounts	of	assets	and	liabilities	that	are	not	readily	apparent	from	other	sources.	Our	actual	results	may	differ	materially	from	these estimates.	Significant	estimates	 inherent	 in	 the	preparation	of	our	consolidated	financial	statements	 include,	but	are	not	 limited	 to,	accounting	for	sales	and	cost recognition,	postretirement	benefit	plans,	environmental	receivables	and	liabilities,	evaluation	of	goodwill	and	other	assets	for	impairment,	income	taxes	including deferred	tax	assets,	fair	value	measurements	and	contingencies.

Sales	and	earnings	 –	We	 record	 net	 sales	 and	 estimated	 profits	 for	 substantially	 all	 of	 our	 contracts	 using	 the	 percentage-of-completion	 method	 for	 cost- reimbursable	and	fixed-price	contracts	for	products	and	services	with	the	U.S.	Government.	Sales	are	recorded	on	all	time-and-materials	contracts	as	the	work	is performed	based	on	agreed-upon	hourly	rates	and	allowable	costs.	We	account	for	our	services	contracts	with	non-U.S.	Government	customers	using	the	services	method of	accounting.	We	classify	net	sales	as	products	or	services	on	our	Statements	of	Earnings	based	on	the	attributes	of	the	underlying	contracts.

Percentage-of-Completion	Method	–	The	percentage-of-completion	method	for	product	contracts	depends	on	the	nature	of	the	products	provided	under	the	contract. For	example,	for	contracts	that	require	us	to	perform	a	significant	level	of	development	effort	in	comparison	to	the	total	value	of	the	contract	and/or	to	deliver	minimal quantities,	sales	are	recorded	using	the	cost-to-cost	method	to	measure	progress	toward	completion.	Under	the	cost-to-cost	method	of	accounting,	we	recognize	sales	and an	estimated	profit	as	costs	are	incurred	based	on	the	proportion	that	the	incurred	costs	bear	to	total	estimated	costs.	For	contracts	that	require	us	to	provide	a	substantial number	of	similar	items	without	a	significant	level	of	development,	we	record	sales	and	an	estimated	profit	on	a	percentage-of-completion	basis	using	units-of-delivery as	the	basis	to	measure	progress	toward	completing	the	contract.	For	contracts	to	provide	services	to	the	U.S.	Government,	sales	are	generally	recorded	using	the	cost-to- cost	method.

Accounting	for	contracts	using	the	percentage-of-completion	method	requires	judgment	relative	to	assessing	risks,	estimating	contract	sales	and	costs	(including estimating	award	and	incentive	fees	and	penalties	related	to	performance)	and	making	assumptions	for	schedule	and	technical	issues.	Due	to	the	number	of	years	it	may take	to	complete	many	of	our	contracts	and	the	scope	and	nature	of	the	work	required	to	be	performed	on	those	contracts,	the	estimation	of	total	sales	and	costs	at completion	is	complicated	and	subject	to	many	variables	and,	accordingly,	is	subject	to	change.	When	adjustments	in	estimated	total	contract	sales	or	estimated	total costs	are	required,	any	changes	from	prior	estimates	are	recognized	in	the	current	period	for	the	inception-to-date	effect	of	such	changes.	When	estimates	of	total	costs	to be	incurred	on	a	contract	exceed	estimates	of	total	sales	to	be	earned,	a	provision	for	the	entire	loss	on	the	contract	is	recorded	in	the	period	in	which	the	loss	is determined.

In	addition,	comparability	of	our	business	segment	sales,	operating	profit	and	operating	margins	may	be	impacted	by	changes	in	profit	booking	rates	on	our contracts	accounted	for	using	the	percentage-of-completion	method	of	accounting.	Increases	in	the	profit	booking	rates,	typically	referred	to	as	risk	retirements,	usually relate	to	revisions	in	the	estimated	total	costs	that	reflect	improved	conditions	on	a	particular	contract.	Conversely,	conditions	on	a	particular	contract	may	deteriorate resulting	in	an	increase	in	the	estimated	total	costs	to	complete	and	a	reduction	in	the	profit	booking	rate.	Increases	or	decreases	in	profit	booking	rates	are	recognized	in the	current	period	and	reflect	the	inception-to-date	effect	of	such	changes.	Segment	operating	profit	and	margins	may	also	be	impacted	favorably	or	unfavorably	by	other items.	Favorable	items	may	include	the	positive	resolution	of	contractual	matters,	cost	recoveries	on	restructuring	charges,	insurance	recoveries	and	gains	on	sales	of assets.	Unfavorable	items	may	include	the	adverse	resolution	of	contractual	matters;	restructuring	charges,	except	for	significant	severance	actions	(such	as	those mentioned	below	in	Note	15)	which	are	excluded	from	segment	operating	results;	reserves	for	disputes;	asset	impairments;	and	losses	on	sales	of	assets.	Segment operating	profit	and	items	such	as	risk	retirements,	reductions	of	profit	booking	rates	or	other	matters	are	presented	net	of	state	income	taxes.

Our	consolidated	net	adjustments	not	related	to	volume,	including	net	profit	booking	rate	adjustments	and	other	matters,	net	of	state	income	taxes,	increased segment	operating	profit,	by	approximately	$1.9	billion	in	2015,	$1.8	billion	in	2014	and	$2.1	billion	in	2013.	These	adjustments	increased	net	earnings	by	approximately $1.2	billion	($3.87	per	share)	in	2015,	$1.1	billion	($3.55	per	share)	in	2014	and	$1.3	billion	($4.09	per	share)	in	2013.

Services	Method	–	For	cost-reimbursable	contracts	for	services	to	non-U.S.	Government	customers,	we	record	net	sales	as	services	are	performed,	except	for	award and	incentive	fees.	Award	and	incentive	fees	are	recorded	when	they	are	fixed	or

determinable,	generally	at	the	date	the	amount	is	communicated	to	us	by	the	customer.	This	approach	results	in	the	recognition	of	such	fees	at	contractual	intervals (typically	every	six	months)	throughout	the	contract	and	is	dependent	on	the	customer's	processes	for	notification	of	awards	and	issuance	of	formal	notifications.	Under fixed-price	service	contracts,	we	are	paid	a	predetermined	fixed	amount	for	a	specified	scope	of	work	and	generally	have	full	responsibility	for	the	costs	associated	with the	contract	and	the	resulting	profit	or	loss.	We	record	net	sales	under	fixed-price	service	contracts	with	non-U.S.	Government	customers	on	a	straight-line	basis	over	the period	of	contract	performance,	unless	evidence	suggests	that	net	sales	are	earned	or	the	obligations	are	fulfilled	in	a	different	pattern.	Costs	for	all	service	contracts	are expensed	as	incurred.

Research	and	development	and	similar	costs	–	Except	for	certain	arrangements	described	below,	we	account	for	independent	research	and	development	costs	as part	of	the	general	and	administrative	costs	that	are	allocated	among	all	of	our	contracts	and	programs	in	progress	under	U.S.	Government	contractual	arrangements	and charged	to	cost	of	sales.	Under	certain	arrangements	in	which	a	customer	shares	in	product	development	costs,	our	portion	of	unreimbursed	costs	is	expensed	as	incurred in	cost	of	sales.	Independent	research	and	development	costs	charged	to	cost	of	sales	totaled	$839	million	in	2015,	$751	million	in	2014	and	$697	million	in	2013.	Costs we	incur	under	customer-sponsored	research	and	development	programs	pursuant	to	contracts	are	included	in	net	sales	and	cost	of	sales.

Stock-based	compensation	–	Compensation	cost	related	to	all	share-based	payments	is	measured	at	the	grant	date	based	on	the	estimated	fair	value	of	the	award. We	generally	recognize	the	compensation	cost	ratably	over	a	three-year	vesting	period.

Income	taxes	–	We	calculate	our	provision	for	income	taxes	using	the	asset	and	liability	method,	under	which	deferred	tax	assets	and	liabilities	are	recognized based	on	the	future	tax	consequences	attributable	to	temporary	differences	that	exist	between	the	financial	statement	carrying	amount	of	assets	and	liabilities	and	their respective	tax	bases,	as	well	as	from	operating	loss	and	tax	credit	carry-forwards.	We	measure	deferred	tax	assets	and	liabilities	using	enacted	tax	rates	that	will	apply	in the	years	in	which	we	expect	the	temporary	differences	to	be	recovered	or	paid.

We	periodically	assess	our	tax	filing	exposures	related	to	periods	that	are	open	to	examination.	Based	on	the	latest	available	information,	we	evaluate	our	tax positions	to	determine	whether	the	position	will	more-likely-than-not	be	sustained	upon	examination	by	the	Internal	Revenue	Service	(IRS)	or	other	taxing	authorities.	If we	cannot	reach	a	more-likely-than-not	determination,	no	benefit	is	recorded.	If	we	determine	that	the	tax	position	is	more-likely-than-not	to	be	sustained,	we	record	the largest	amount	of	benefit	that	is	more-likely-than-not	to	be	realized	when	the	tax	position	is	settled.	We	record	interest	and	penalties	related	to	income	taxes	as	a component	of	income	tax	expense	on	our	Statements	of	Earnings.	Interest	and	penalties	were	not	material.

Cash	and	cash	equivalents	–	Cash	equivalents	include	highly	liquid	instruments	with	original	maturities	of	90	days	or	less.

Receivables	–	Receivables	include	amounts	billed	and	currently	due	from	customers	and	unbilled	costs	and	accrued	profits	primarily	related	to	sales	on	long-term contracts	that	have	been	recognized	but	not	yet	billed	to	customers.	Pursuant	to	contract	provisions,	agencies	of	the	U.S.	Government	and	certain	other	customers	have title	to,	or	a	security	interest	in,	assets	related	to	such	contracts	as	a	result	of	advances,	performance-based	payments	and	progress	payments.	We	reflect	those	advances and	payments	as	an	offset	to	the	related	receivables	balance	for	contracts	that	we	account	for	on	a	percentage-of-completion	basis	using	the	cost-to-cost	method	to measure	progress	towards	completion.

Inventories	–	We	record	inventories	at	the	lower	of	cost	or	estimated	net	realizable	value.	Costs	on	long-term	contracts	and	programs	in	progress	represent recoverable	costs	incurred	for	production	or	contract-specific	facilities	and	equipment,	allocable	operating	overhead,	advances	to	suppliers	and,	in	the	case	of	contracts with	the	U.S.	Government	and	substantially	all	other	governments,	research	and	development	and	general	and	administrative	expenses.	Pursuant	to	contract	provisions, agencies	of	the	U.S.	Government	and	certain	other	customers	have	title	to,	or	a	security	interest	in,	inventories	related	to	such	contracts	as	a	result	of	advances, performance-based	payments	and	progress	payments.	We	reflect	those	advances	and	payments	as	an	offset	against	the	related	inventory	balances	for	contracts	that	we account	for	on	a	percentage-of-completion	basis	using	units-of-delivery	as	the	basis	to	measure	progress	toward	completing	the	contract.	We	determine	the	costs	of	other product	and	supply	inventories	by	the	first-in	first-out	or	average	cost	methods.

Property,	 plant	 and	 equipment	–	We	record	property,	plant	and	equipment	at	cost.	We	provide	for	depreciation	and	amortization	on	plant	and	equipment generally	using	accelerated	methods	during	the	first	half	of	the	estimated	useful	lives	of	the	assets	and	the	straight-line	method	thereafter.	The	estimated	useful	lives	of our	plant	and	equipment	generally	range	from

10	to	40	years	for	buildings	and	five	to	15	years	for	machinery	and	equipment.	No	depreciation	expense	is	recorded	on	construction	in	progress	until	such	assets	are placed	into	operation.	Depreciation	expense	related	to	plant	and	equipment	was	$738	million	in	2015,	$739	million	in	2014	and	$714	million	in	2013.

We	review	the	carrying	amounts	of	long-lived	assets	for	impairment	if	events	or	changes	in	the	facts	and	circumstances	indicate	that	their	carrying	amounts	may not	be	recoverable.	We	assess	impairment	by	comparing	the	estimated	undiscounted	future	cash	flows	of	the	related	asset	grouping	to	its	carrying	amount.	If	an	asset	is determined	to	be	impaired,	we	recognize	an	impairment	charge	in	the	current	period	for	the	difference	between	the	fair	value	of	the	asset	and	its	carrying	amount.

Capitalized	software	–	We	capitalize	certain	costs	associated	with	the	development	or	purchase	of	internal-use	software.	The	amounts	capitalized	are	included	in other	noncurrent	assets	on	our	Balance	Sheets	and	are	amortized	on	a	straight-line	basis	over	the	estimated	useful	life	of	the	resulting	software,	which	ranges	from	two	to six	years.	As	of	December	31,	2015	and	2014,	capitalized	software	totaled	$481	million	and	$547	million,	net	of	accumulated	amortization	of	$1.9	billion	and	$1.8 billion.	No	amortization	expense	is	recorded	until	the	software	is	ready	for	its	intended	use.	Amortization	expense	related	to	capitalized	software	was	$172	million	in 2015,	$206	million	in	2014	and	$228	million	in	2013.

Goodwill	–	The	assets	and	liabilities	of	acquired	businesses	are	recorded	under	the	acquisition	method	of	accounting	at	their	estimated	fair	values	at	the	date	of acquisition.	Goodwill	represents	costs	in	excess	of	fair	values	assigned	to	the	underlying	identifiable	net	assets	of	acquired	businesses.

We	perform	an	impairment	test	of	our	goodwill	at	least	annually	in	the	fourth	quarter	and	more	frequently	whenever	certain	events	or	changes	in	circumstances indicate	 the	 carrying	 value	 of	 goodwill	 may	 be	 impaired.	 Such	 events	 or	 changes	 in	 circumstances	 may	 include	 a	 significant	 deterioration	 in	 overall	 economic conditions,	changes	in	the	business	climate	of	our	industry,	a	decline	in	our	market	capitalization,	operating	performance	indicators,	competition,	reorganizations	of	our business	or	the	disposal	of	all	or	a	portion	of	a	reporting	unit.	Our	goodwill	has	been	allocated	to	and	is	tested	for	impairment	at	a	level	referred	to	as	the	reporting	unit, which	is	our	business	segment	level	or	a	level	below	the	business	segment.	The	level	at	which	we	test	goodwill	for	impairment	requires	us	to	determine	whether	the operations	below	the	business	segment	constitute	a	business	for	which	discrete	financial	information	is	available	and	segment	management	regularly	reviews	the operating	results.

Under	step	one	of	the	quantitative	impairment	test,	we	compare	the	fair	value	of	each	reporting	unit	to	its	carrying	value,	including	goodwill.	If	the	fair	value	of	a reporting	unit	exceeds	its	carrying	value,	goodwill	of	the	reporting	unit	is	not	impaired.	If	the	carrying	value	of	a	reporting	unit	exceeds	its	fair	value,	we	then	perform step	two	of	the	quantitative	impairment	test	and	compare	the	implied	value	of	the	reporting	unit's	goodwill	with	the	carrying	value	of	its	goodwill.	The	implied	value	of the	reporting	unit's	goodwill	is	calculated	by	creating	a	hypothetical	balance	sheet	as	if	the	reporting	unit	had	just	been	acquired.	This	balance	sheet	contains	all	assets and	liabilities	recorded	at	fair	value	(including	any	intangible	assets	that	may	not	have	any	corresponding	carrying	value	in	our	balance	sheet).	The	implied	value	of	the reporting	unit's	goodwill	is	calculated	by	subtracting	the	fair	value	of	the	net	assets	from	the	fair	value	of	the	reporting	unit.	If	the	carrying	value	of	the	reporting	unit's goodwill	exceeds	the	implied	value	of	that	goodwill,	an	impairment	loss	is	recognized	in	an	amount	equal	to	that	excess.

We	estimate	the	fair	value	of	each	reporting	unit	using	a	combination	of	a	discounted	cash	flow	(DCF)	analysis	and	market-based	valuation	methodologies	such	as comparable	public	company	trading	values	and	values	observed	in	recent	business	acquisitions.	Determining	fair	value	requires	the	exercise	of	significant	judgments, including	judgments	about	the	amount	and	timing	of	expected	future	cash	flows,	long-term	growth	rates,	discount	rates	and	relevant	comparable	public	company earnings	multiples	and	relevant	transaction	multiples.	The	cash	flows	employed	in	the	DCF	analyses	are	based	on	our	best	estimate	of	future	sales,	earnings	and	cash flows	after	considering	factors	such	as	general	market	conditions,	U.S.	Government	budgets,	existing	firm	orders,	expected	future	orders,	contracts	with	suppliers,	labor agreements,	changes	in	working	capital,	long-term	business	plans	and	recent	operating	performance.	The	discount	rates	utilized	in	the	DCF	analysis	are	based	on	the respective	reporting	unit's	weighted	average	cost	of	capital,	which	takes	into	account	the	relative	weights	of

each	component	of	capital	structure	(equity	and	debt)	and	represents	the	expected	cost	of	new	capital,	adjusted	as	appropriate	to	consider	the	risk	inherent	in	future	cash flows	of	the	respective	reporting	unit.

In	the	fourth	quarter	of	2015,	we	performed	our	annual	goodwill	impairment	test	for	each	of	our	reporting	units.	During	the	fourth	quarter	of	2015,	we	realigned certain	programs	between	our	business	segments	in	connection	with	our	strategic	review	of	our	government	IT	and	technical	services	businesses.	As	part	of	the realignment,	goodwill	was	reallocated	between	affected	reporting	units	on	a	relative	fair	value	basis.	We	performed	goodwill	impairment	tests	prior	and	subsequent	to	the realignment.	The	results	of	our	2015	annual	impairment	tests	of	goodwill	indicated	that	no	impairment	existed.

In	the	fourth	quarter	of	2014,	we	completed	our	annual	goodwill	impairment	test	for	each	of	our	reporting	units.	The	results	of	these	tests	indicated	that	the estimated	fair	values	of	our	reporting	units	exceeded	their	carrying	values,	with	the	exception	of	our	Technical	Services	reporting	unit	within	our	IS&GS	business segment.	The	impact	of	market	pressures	such	as	lower	in-theater	support	as	troop	levels	are	drawn	down	and	increased	re-competition	on	existing	contracts	that	are awarded	primarily	on	the	basis	of	price	adversely	impacted	the	fair	value	of	this	reporting	unit.	As	a	result,	we	compared	the	implied	value	of	that	reporting	unit's goodwill	with	the	carrying	value	of	its	goodwill,	and	since	the	carrying	value	exceeded	the	implied	value,	we	recorded	a	non-cash	impairment	charge	of	$119	million	in the	fourth	quarter	of	2014	equal	to	that	differential.	This	charge	reduced	our	net	earnings	by	$107	million	($.33	per	share).

During	the	fourth	quarter	of	2013,	due	to	the	continuing	impact	of	defense	budget	reductions	and	related	competitive	pressures	on	the	Technical	Services	business, we	recorded	a	non-cash	goodwill	impairment	charge	of	$195	million.	This	charge	reduced	our	2013	net	earnings	by	$176	million	($.54	per	share).

Intangible	assets	–	Intangible	assets	from	acquired	businesses	are	recognized	at	their	estimated	fair	values	at	the	date	of	acquisition	and	consist	of	customer programs,	trademarks,	customer	relationships,	technology	and	other	intangible	assets.	Customer	programs	include	values	assigned	to	major	programs	of	acquired businesses	and	represent	the	aggregate	value	associated	with	the	customer	relationships,	contracts,	technology	and	trademarks	underlying	the	associated	program. Acquired	intangibles	deemed	to	have	indefinite	lives	are	not	amortized,	but	are	subject	to	annual	impairment	testing.	This	testing	compares	carrying	value	to	fair	value and,	when	appropriate,	the	carrying	value	of	these	assets	is	reduced	to	fair	value.	Finite-lived	intangibles	are	amortized	to	expense	over	the	applicable	useful	lives, ranging	from	three	to	twenty	years,	based	on	the	nature	of	the	asset	and	the	underlying	pattern	of	economic	benefit	as	reflected	by	future	net	cash	inflows.

Customer	advances	and	amounts	in	excess	of	cost	incurred	–	We	receive	advances,	performance-based	payments	and	progress	payments	from	customers	that may	exceed	costs	incurred	on	certain	contracts,	including	contracts	with	agencies	of	the	U.S.	Government.	We	classify	such	advances,	other	than	those	reflected	as	a reduction	of	receivables	or	inventories	as	discussed	above,	as	current	liabilities.

Debt	issuance	costs	–	In	2015,	we	early	adopted	a	new	standard	of	the	Financial	Accounting	Standards	Board	(FASB)	which	simplifies	the	presentation	of	debt issuance	costs.	In	accordance	with	the	new	standard,	we	now	reflect	debt	issuance	costs	as	a	reduction	from	the	face	amount	of	debt	on	our	consolidated	balance	sheets. These	costs,	which	are	$95	million	and	$27	million	as	of	December	31,	2015	and	2014,	are	amortized	as	interest	expense	over	the	life	of	the	related	debt.	In	prior	year presentation,	these	costs	were	reflected	within	other	noncurrent	assets	on	our	consolidated	balance	sheets.

Postretirement	benefit	plans	–	Many	of	our	employees	are	covered	by	defined	benefit	pension	plans	and	we	provide	certain	health	care	and	life	insurance	benefits to	eligible	retirees	(collectively,	postretirement	benefit	plans).	GAAP	requires	that	the	amounts	we	record	related	to	our	postretirement	benefit	plans	be	computed,	based on	service	to	date,	using	actuarial	valuations	that	are	based	in	part	on	certain	key	economic	assumptions	we	make,	including	the	discount	rate,	the	expected	long-term rate	of	return	on	plan	assets	and	other	actuarial	assumptions	including	participant	longevity	(also	known	as	mortality)	estimates,	health	care	cost	trend	rates	and employee	turnover,	each	as	appropriate	based	on	the	nature	of	the	plans.	We	recognize	on	a	plan-by-plan	basis	the	funded	status	of	our	postretirement	benefit	plans under	 GAAP	 as	 either	 an	 asset	 recorded	 within	 other	 noncurrent	 assets	 or	 a	 liability	 recorded	 within	 noncurrent	 liabilities	 on	 our	 Balance	 Sheets.	 There	 is	 a corresponding	non-cash	adjustment	to	accumulated	other	comprehensive	loss,	net	of	tax	benefits	recorded	as	deferred	tax	assets,	in	stockholders'	equity.	The	GAAP funded	status	is	measured	as	the	difference	between	the	fair	value	of	the	plan's	assets	and	the	benefit	obligation	of	the	plan.	The	funded	status	under	the	Employee Retirement	Income	Security	Act	of	1974	(ERISA),	as	amended	by	the	Pension	Protection	Act	of	2006	(PPA),	is	calculated	on	a	different	basis	than	under	GAAP.

Environmental	matters	–	We	record	a	liability	for	environmental	matters	when	it	is	probable	that	a	liability	has	been	incurred	and	the	amount	can	be	reasonably estimated.	The	amount	of	liability	recorded	is	based	on	our	estimate	of	the	costs	to	be	incurred	for	remediation	at	a	particular	site.	We	do	not	discount	the	recorded liabilities,	as	the	amount	and	timing	of

future	cash	payments	are	not	fixed	or	cannot	be	reliably	determined.	Our	environmental	liabilities	are	recorded	on	our	Balance	Sheets	within	other	liabilities,	both current	and	noncurrent.	We	expect	to	include	a	substantial	portion	of	environmental	costs	in	our	net	sales	and	cost	of	sales	in	future	periods	pursuant	to	U.S.	Government agreement	or	regulation.	At	the	time	a	liability	is	recorded	for	future	environmental	costs,	we	record	a	receivable	for	estimated	future	recovery	considered	probable through	the	pricing	of	products	and	services	to	agencies	of	the	U.S.	Government,	regardless	of	the	contract	form	(e.g.,	cost-reimbursable,	fixed-price).	We	continuously evaluate	the	recoverability	of	our	environmental	receivables	by	assessing,	among	other	factors,	U.S.	Government	regulations,	our	U.S.	Government	business	base	and contract	mix	and	our	history	of	receiving	reimbursement	of	such	costs.	We	include	the	portion	of	those	environmental	costs	expected	to	be	allocated	to	our	non-U.S. Government	contracts,	or	that	is	determined	to	not	be	recoverable	under	U.S.	Government	contracts,	in	our	cost	of	sales	at	the	time	the	liability	is	established.	Our environmental	 receivables	 are	 recorded	 on	 our	 Balance	 Sheets	 within	 other	 assets,	 both	 current	 and	 noncurrent.	 We	 project	 costs	 and	 recovery	 of	 costs	 over approximately	20	years.

Investments	in	marketable	securities	–	Investments	in	marketable	securities	consist	of	debt	and	equity	securities	and	are	classified	as	trading	securities.	As	of December	31,	2015	and	2014,	the	fair	value	of	our	trading	securities	totaled	$1.1	billion	and	$1.1	billion	and	was	included	in	other	noncurrent	assets	on	our	Balance Sheets.	Our	trading	securities	are	held	in	a	separate	trust,	which	includes	investments	to	fund	our	deferred	compensation	plan	liabilities.	Net	losses	on	trading	securities in	2015	were	$11	million	and	net	gains	on	trading	securities	in	2014	and	2013	were	$65	million	and	$64	million.	Gains	and	losses	on	these	investments	are	included	in other	unallocated,	net	within	cost	of	sales	on	our	Statements	of	Earnings	in	order	to	align	the	classification	of	changes	in	the	market	value	of	investments	held	for	the	plan with	changes	in	the	value	of	the	corresponding	plan	liabilities.

Equity	method	investments	–	Investments	where	we	have	the	ability	to	exercise	significant	influence,	but	do	not	control,	are	accounted	for	under	the	equity method	of	accounting	and	are	included	in	other	noncurrent	assets	on	our	Balance	Sheets.	Significant	influence	typically	exists	if	we	have	a	20%	to	50%	ownership interest	in	the	investee.	Under	this	method	of	accounting,	our	share	of	the	net	earnings	or	losses	of	the	investee	is	included	in	operating	profit	in	other	income,	net	on	our Statements	of	Earnings	since	the	activities	of	the	investee	are	closely	aligned	with	the	operations	of	the	business	segment	holding	the	investment.	We	evaluate	our	equity method	investments	for	impairment	whenever	events	or	changes	in	circumstances	indicate	that	the	carrying	amounts	of	such	investments	may	be	impaired.	If	a	decline	in the	value	of	an	equity	method	investment	is	determined	to	be	other	than	temporary,	a	loss	is	recorded	in	earnings	in	the	current	period.	As	of	December	31,	2015	and 2014,	our	equity	method	investments	totaled	$1.3	billion	and	$971	million,	which	primarily	are	composed	of	our	Space	Systems	business	segment's	investment	in United	Launch	Alliance	(ULA),	as	further	described	in	Note	14,	and	our	Aeronautics	and	MST	business	segments'	investments	in	Advanced	Military	Maintenance, Repair	and	Overhaul	Center.	Our	share	of	net	earnings	related	to	our	equity	method	investees	was	$343	million	in	2015,	$342	million	in	2014	and	$321	million	in	2013, of	which	approximately	$245	million,	$280	million	and	$300	million	related	to	our	Space	Systems	business	segment.

Derivative	financial	instruments	–	We	use	derivative	instruments	principally	to	reduce	our	exposure	to	market	risks	from	changes	in	foreign	currency	exchange rates	and	interest	rates.	We	do	not	enter	into	or	hold	derivative	instruments	for	speculative	trading	purposes.	We	transact	business	globally	and	are	subject	to	risks associated	with	changing	foreign	currency	exchange	rates.	We	enter	into	foreign	currency	hedges	such	as	forward	and	option	contracts	that	change	in	value	as	foreign currency	exchange	rates	change.	These	contracts	hedge	forecasted	foreign	currency	 transactions	 in	order	 to	mitigate	fluctuations	 in	our	earnings	and	cash	flows associated	with	changes	in	foreign	currency	exchange	rates.	We	designate	foreign	currency	hedges	as	cash	flow	hedges.	We	also	are	exposed	to	the	impact	of	interest rate	changes	primarily	through	our	borrowing	activities.	For	fixed	rate	borrowings,	we	may	use	variable	interest	rate	swaps,	effectively	converting	fixed	rate	borrowings to	variable	rate	borrowings	in	order	to	reduce	the	amount	of	interest	paid.	These	swaps	are	designated	as	fair	value	hedges.	For	variable	rate	borrowings,	we	may	use fixed	interest	rate	swaps,	effectively	converting	variable	rate	borrowings	to	fixed	rate	borrowings	in	order	to	mitigate	the	impact	of	interest	rate	changes	on	earnings. These	swaps	are	designated	as	cash	flow	hedges.	We	also	may	enter	into	derivative	instruments	that	are	not	designated	as	hedges	and	do	not	qualify	for	hedge accounting,	which	are	intended	to	mitigate	certain	economic	exposures.

We	record	derivatives	at	their	fair	value.	The	classification	of	gains	and	losses	resulting	from	changes	in	the	fair	values	of	derivatives	is	dependent	on	our	intended use	of	the	derivative	and	its	resulting	designation.	Adjustments	to	reflect	changes	in	fair	values	of	derivatives	attributable	to	the	effective	portion	of	hedges	are	either reflected	in	earnings	and	largely	offset	by	corresponding	adjustments	to	the	hedged	items	or	reflected	net	of	income	taxes	in	accumulated	other	comprehensive	loss	until the	hedged	transaction	is	recognized	in	earnings.	Changes	in	the	fair	value	of	the	derivatives	that	are	attributable	to	the	ineffective	portion	of	the	hedges	or	of	derivatives that	are	not	considered	to	be	highly	effective	hedges,	if	any,	are	immediately	recognized	in	earnings.	The	aggregate	notional	amount	of	our	outstanding	interest	rate swaps	at	December	31,

2015	and	2014	was	$1.5	billion	and	$1.3	billion.	The	aggregate	notional	amount	of	our	outstanding	foreign	currency	hedges	at	December	31,	2015	and	2014	was	$4.1 billion	and	$804	million.	Derivative	instruments	did	not	have	a	material	impact	on	net	earnings	and	comprehensive	income	during	2015,	2014	and	2013.	Substantially all	of	our	derivatives	are	designated	for	hedge	accounting.	See	Note	16	for	more	information	on	the	fair	value	measurements	related	to	our	derivative	instruments.

Recent	Accounting	Pronouncements	–	In	May	2014,	the	FASB	issued	a	new	standard	that	will	change	the	way	we	recognize	revenue	and	significantly	expand	the disclosure	requirements	for	revenue	arrangements.	On	July	9,	2015,	the	FASB	approved	a	one-year	deferral	of	the	effective	date	of	the	standard	to	2018	for	public companies,	with	an	option	that	would	permit	companies	to	adopt	the	standard	in	2017.	Early	adoption	prior	to	2017	is	not	permitted.	The	new	standard	may	be	adopted either	 retrospectively	 or	 on	 a	 modified	 retrospective	 basis	 whereby	 the	 new	 standard	 would	 be	 applied	 to	 new	 contracts	 and	 existing	 contracts	 with	 remaining performance	obligations	as	of	the	effective	date,	with	a	cumulative	catch-up	adjustment	recorded	to	beginning	retained	earnings	at	the	effective	date	for	existing contracts	with	remaining	performance	obligations.	In	addition,	the	FASB	is	contemplating	making	additional	changes	to	certain	elements	of	the	new	standard.	We	are currently	evaluating	the	methods	of	adoption	allowed	by	the	new	standard	and	the	effect	the	standard	is	expected	to	have	on	our	consolidated	financial	statements	and related	disclosures.	As	the	new	standard	will	supersede	substantially	all	existing	revenue	guidance	affecting	us	under	GAAP,	it	could	impact	revenue	and	cost	recognition on	thousands	of	contracts	across	all	our	business	segments,	in	addition	to	our	business	processes	and	our	information	technology	systems.	As	a	result,	our	evaluation	of the	effect	of	the	new	standard	will	extend	over	future	periods.

# Note	2	–	Earnings	Per	Share

The	weighted	average	number	of	shares	outstanding	used	to	compute	earnings	per	common	share	were	as	follows	(in	millions):

|  | 2015 | 2014 | 2013 |
| :--- | :--- | :--- | :--- |
| Weighted\taverage\tcommon\tshares\toutstanding\tfor\tbasic\tcomputations | \t310.3 | \t316.8 | \t320.9 |
| Weighted\taverage\tdilutive\teffect\tof\tequity\tawards | 4.4 | 5.6 | 5.6 |
| Weighted\taverage\tcommon\tshares\toutstanding\tfor\tdiluted\tcomputations | \t314.7 | \t322.4 | \t326.5 |

We	compute	basic	and	diluted	earnings	per	common	share	by	dividing	net	earnings	by	the	respective	weighted	average	number	of	common	shares	outstanding	for the	periods	presented.	Our	calculation	of	diluted	earnings	per	common	share	also	includes	the	dilutive	effects	for	the	assumed	vesting	of	outstanding	restricted	stock units	and	exercise	of	outstanding	stock	options	based	on	the	treasury	stock	method.

The	computation	of	diluted	earnings	per	common	share	excluded	2.4	million	stock	options	for	the	year	ended	December	31,	2013	because	their	inclusion	would have	been	anti-dilutive,	primarily	due	to	their	exercise	prices	exceeding	the	average	market	prices	of	our	common	stock	during	the	respective	periods.	There	were	no anti-dilutive	equity	awards	for	the	years	ended	December	31,	2015	and	2014.

# Note	3	–	Acquisitions	and	Divestitures

# Acquisitions

On	November	6,	2015,	we	completed	the	acquisition	of	Sikorsky	Aircraft	Corporation	and	certain	affiliated	companies	(collectively	"Sikorsky")	from	United Technologies	Corporation	(UTC)	and	certain	of	UTC's	subsidiaries.	The	purchase	price	of	the	acquisition	was	$9.0	billion,	net	of	cash	acquired.	As	a	result	of	the acquisition,	Sikorsky	became	a	wholly-owned	subsidiary	of	ours.	Sikorsky	is	a	global	company	primarily	engaged	in	the	research,	design,	development,	manufacture and	support	of	military	and	commercial	helicopters.	Sikorsky's	products	include	military	helicopters	such	as	the	H-60	Black	Hawk,	MH-60R	Seahawk,	CH-53K,	H-92; and	commercial	helicopters	such	as	the	S-76	and	S-92.	The	acquisition	enables	us	to	extend	our	core	business	into	the	military	and	commercial	rotary	wing	markets, allowing	us	to	strengthen	our	position	in	the	aerospace	and	defense	industry.	Further,	this	acquisition	will	expand	our	presence	in	commercial	and	international	markets. Sikorsky	has	been	aligned	under	our	MST	business	segment.

To	fund	the	$9.0	billion	acquisition	price,	we	utilized	$6.0	billion	of	proceeds	borrowed	under	our	364-day	revolving	credit	facility	(the	364-day	Facility),	$2.0 billion	of	cash	on	hand	and	$1.0	billion	from	the	issuance	of	commercial	paper.	In	the	fourth	quarter	of	2015,	we	repaid	all	outstanding	borrowings	under	the	364-day Facility	with	the	proceeds	from	the	issuance	of	$7.0	billion	of	fixed	interest-rate	long-term	notes	in	a	public	offering	(the	November	2015	Notes).	In	the	fourth	quarter	of 2015,	we	also	repaid	the	$1.0	billion	in	commercial	paper	borrowings	(see	Note	10).

We	and	UTC	made	a	joint	election	under	Section	338(h)(10)	of	the	Internal	Revenue	Code,	which	treats	the	transaction	as	an	asset	purchase	for	tax	purposes.	This election	generates	a	cash	tax	benefit	with	an	estimated	net	present	value	of	$1.9	billion	for	Lockheed	Martin	and	its	stockholders.

# Preliminary	Allocation	of	Acquisition	Price	to	Assets	Acquired	and	Liabilities	Assumed

We	accounted	for	the	acquisition	of	Sikorsky	as	a	business	combination,	which	requires	us	to	record	the	assets	acquired	and	liabilities	assumed	at	fair	value.	The amount	by	which	the	purchase	price	exceeds	the	fair	value	of	the	net	assets	acquired	is	recorded	as	goodwill.	We	have	commenced	the	appraisals	necessary	to	assess	the fair	values	of	the	tangible	and	intangible	assets	acquired	and	liabilities	assumed	and	the	amount	of	goodwill	to	be	recognized	as	of	the	acquisition	date.	The	amounts recorded	for	certain	assets	and	liabilities	are	preliminary	in	nature	and	are	subject	to	adjustment	as	additional	information	is	obtained	about	the	facts	and	circumstances that	existed	as	of	the	acquisition	date.	The	final	determination	of	the	fair	values	of	certain	assets	and	liabilities	will	be	completed	within	the	measurement	period	of	up	to one	year	from	the	acquisition	date	permitted	under	GAAP.	The	size,	breadth,	and	timing	of	the	Sikorsky	acquisition	could	necessitate	the	need	to	use	the	full	one	year measurement	period	to	adequately	analyze	and	assess	a	number	of	the	factors	used	in	establishing	the	asset	and	liability	fair	values	as	of	the	acquisition	date	including contractual	and	operational	factors	underlying	the	customer	programs	intangible	assets,	the	tradename	intangible	asset,	customer	contractual	obligations,	property,	plant and	equipment,	inventories,	receivables	and	deferred	revenue;	and	the	assumptions	underpinning	certain	reserves	such	as	those	for	environmental	and	legal	obligations. The	final	values	may	also	result	in	changes	to	depreciation	and	amortization	expense	related	to	certain	assets	such	as	buildings,	equipment	and	intangible	assets.	Any potential	adjustments	made	could	be	material	in	relation	to	the	preliminary	values	presented	in	the	table	below.

The	following	table	summarizes	the	estimated	fair	values	of	the	assets	acquired	and	liabilities	assumed	at	the	acquisition	date	(in	millions):

(a) Recorded	in	Other	noncurrent	liabilities	on	the	consolidated	balance	sheet.

Intangible	assets	related	to	customer	programs	were	recognized	for	each	major	helicopter	and	aftermarket	program	and	represent	the	aggregate	value	associated with	the	customer	relationships,	contracts,	technology	and	tradenames	underlying	the	associated	program.	These	intangible	assets	will	be	amortized	over	a	weighted- average	useful	life	of	approximately	15	years	in	accordance	with	the	underlying	pattern	of	economic	benefit	as	reflected	by	the	future	net	cash	inflows.

Customer	contractual	obligations	represent	liabilities	on	certain	development	programs	where	the	expected	costs	exceed	the	expected	sales	under	contract.	We measured	these	liabilities	based	on	the	price	to	transfer	the	obligation	to	a	market	participant	at	the	measurement	date,	assuming	that	the	liability	will	remain	outstanding in	the	marketplace.	Based	on	the	estimated	net	cash	outflows	of	the	developmental	programs	plus	a	reasonable	contracting	profit	margin	required	to	transfer	the	contracts to	market	participants,	we	recorded	assumed	liabilities	of	approximately	$480	million.	These	liabilities	will	be	liquidated	in	accordance	with	the	underlying	economic pattern	of	the	contractual	obligations,	as	reflected	by	the	estimated	future	net	cash	outflows	incurred	on	the	associated	contracts.	Estimated	liquidation	of	the	contractual obligation	is	estimated	is	as	follows:	$85	million	in	2016,	$90	million	in	2017,	$65	million	in	2018,	$60	million	in	2019,	$60	million	in	2020	and	$110	million thereafter.

The	fair	values	of	the	assets	acquired	and	liabilities	assumed	were	preliminarily	determined	using	income,	market	and	cost	valuation	methodologies.	The	fair	value measurements	were	estimated	using	significant	inputs	that	are	not	observable	in	the	market	and	thus	represent	a	Level	3	measurement	as	defined	in	Accounting Standards	Codification	(ASC)	820.	The	income	approach	was	primarily	used	to	value	the	customer	programs	and	trademarks	intangible	assets.	The	income	approach indicates	value	for	an	asset	or	liability	based	on	the	present	value	of	cash	flow	projected	to	be	generated	over	the	remaining	economic	life	of	the	asset	or	liability	being measured.	Both	the	amount	and	the	duration	of	the	cash	flows	are	considered	from	a	market	participant	perspective.	Our	estimates	of	market	participant	net	cash	flows considered	historical	and	projected	pricing,	remaining	developmental	effort,	operational	performance	 including	company	specific	synergies,	aftermarket	retention, product	life	cycles,	material	and	labor	pricing,	and	other	relevant	customer,	contractual	and	market	factors.	Where	appropriate,	the	net	cash	flows	are	adjusted	to	reflect the	uncertainties	associated	with	the	underlying	assumptions,	as	well	as	the	risk	profile	of	the	net	cash	flows	utilized	in	the	valuation.	The	adjusted	future	cash	flows	are then	discounted	to	present

value	using	an	appropriate	discount	rate.	Projected	cash	flow	is	discounted	at	a	required	rate	of	return	that	reflects	the	relative	risk	of	achieving	the	cash	flow	and	the time	value	of	money.	The	market	approach	is	a	valuation	technique	that	uses	prices	and	other	relevant	information	generated	by	market	transactions	involving	identical or	comparable	assets,	liabilities,	or	a	group	of	assets	and	liabilities.	Valuation	techniques	consistent	with	the	market	approach	often	use	market	multiples	derived	from	a set	of	comparables.	The	cost	approach,	which	estimates	value	by	determining	the	current	cost	of	replacing	an	asset	with	another	of	equivalent	economic	utility,	was	used, as	appropriate,	for	property,	plant	and	equipment.	The	cost	to	replace	a	given	asset	reflects	the	estimated	reproduction	or	replacement	cost	for	the	property,	less	an allowance	for	loss	in	value	due	to	depreciation.

The	preliminary	purchase	price	allocation	resulted	in	the	recognition	of	$2.8	billion	of	goodwill,	all	of	which	is	expected	to	be	amortizable	for	tax	purposes.	All	of the	goodwill	was	assigned	to	our	MST	business	segment.	The	goodwill	recognized	is	attributable	to	expected	revenue	synergies	generated	by	the	integration	of	our products	and	technologies	with	those	of	Sikorsky,	costs	synergies	resulting	from	the	consolidation	or	elimination	of	certain	functions,	and	intangible	assets	that	do	not qualify	for	separate	recognition,	such	as	the	assembled	workforce	of	Sikorsky.

Determining	the	fair	value	of	assets	acquired	and	liabilities	assumed	requires	the	exercise	of	significant	judgments,	including	the	amount	and	timing	of	expected future	cash	flows,	long-term	growth	rates	and	discount	rates.	The	cash	flows	employed	in	the	DCF	analyses	are	based	on	our	best	estimate	of	future	sales,	earnings	and cash	flows	after	considering	factors	such	as	general	market	conditions,	customer	budgets,	existing	firm	orders,	expected	future	orders,	contracts	with	suppliers,	labor agreements,	changes	in	working	capital,	long	term	business	plans	and	recent	operating	performance.	Use	of	different	estimates	and	judgments	could	yield	different results.

# Impact	to	2015	Financial	Results

Sikorsky's	financial	results	have	been	included	in	our	consolidated	financial	results	only	for	the	period	from	the	November	6,	2015	acquisition	date	through December	31,	2015.	As	a	result,	our	consolidated	financial	results	for	the	year	ended	December	31,	2015	do	not	reflect	a	full	year	of	Sikorsky's	results.	From	the November	6,	2015	acquisition	date	through	December	31,	2015,	Sikorsky	generated	net	sales	of	approximately	$400	million	and	operating	loss	of	approximately	$45 million,	inclusive	of	intangible	amortization	and	adjustments	required	to	account	for	the	acquisition.

We	incurred	approximately	$38	million	of	non-recoverable	transaction	costs	associated	with	the	Sikorsky	acquisition	in	2015	that	were	expensed	as	incurred.	These costs	are	included	in	"Other	income,	net"	on	our	Consolidated	Statements	of	Earnings.	We	also	incurred	approximately	$48	million	in	costs	associated	with	issuing	the $7.0	billion	November	2015	Notes	used	to	repay	all	outstanding	borrowings	under	the	364-day	Facility	used	to	finance	the	acquisition.	The	financing	costs	were recorded	as	a	reduction	of	debt	and	will	be	amortized	to	interest	expense	over	the	term	of	the	related	debt.

# Supplemental	Pro	Forma	Financial	Information	(unaudited)

The	following	table	presents	summarized	unaudited	pro	forma	financial	information	as	if	Sikorsky	had	been	included	in	our	financial	results	for	the	entire	years	in 2015	and	2014	(in	millions):

|  | 2015 | 2014 |
| :--- | :--- | :--- |
| Net\tSales | $\t50,962 | $ \t53,023 |
| Net\tEarnings\tfrom\tcontinuing\toperations | 3,538 | 3,480 |
| Basic\tearnings\tper\tcommon\tshare\tfrom\tcontinuing\toperations | 11.40 | 10.99 |
| Diluted\tearnings\tper\tcommon\tshare\tfrom\tcontinuing\toperations | 11.24 | 10.79 |

The	unaudited	supplemental	pro	forma	financial	data	above	has	been	calculated	after	applying	our	accounting	policies	and	adjusting	the	historical	results	of Sikorsky	with	pro	forma	adjustments,	net	of	tax,	that	assume	the	acquisition	occurred	on	January	1,	2014.	Significant	pro	forma	adjustments	include	the	recognition	of additional	amortization	expense	related	to	acquired	intangible	assets	and	additional	interest	expense	related	to	the	short-term	debt	used	to	finance	the	acquisition.	These adjustments	assume	the	application	of	fair	value	adjustments	to	intangibles	and	the	debt	issuance	occurred	on	January	1,	2014	and	are	as	follows:	amortization	expense of	$125	million	and	$148	million	in	2015	and	2014,	respectively;	and	interest	expense	$42	million	and	$48	million	in	2015	and	2014,	respectively.	In	addition, significant	nonrecurring	adjustments	include	the	elimination	of	a	$72	million	pension	curtailment	loss,	net	of	tax,	recognized	in	2015	and	the	elimination	of	a	$58	million income	tax	charge	related	to	historic	earnings	of	foreign	subsidiaries	recognized	by	Sikorsky	in	2015.

The	unaudited	supplemental	pro	forma	financial	information	also	reflects	an	increase	in	interest	expense,	net	of	tax,	of	$109	million	and	$121	million	in	2015	and 2014,	respectively.	The	increase	in	interest	expense	is	the	result	of	assuming	the	November	2015	Notes	were	issued	on	January	1,	2014.	Proceeds	of	the	November	2015 Notes	were	used	to	repay	all	outstanding	borrowings	under	the	364-day	Facility	used	to	finance	a	portion	of	the	purchase	of	Sikorsky,	as	contemplated	at	the	date	of acquisition.

The	unaudited	supplemental	pro	forma	financial	information	does	not	reflect	the	realization	of	any	expected	ongoing	cost	or	revenue	synergies	relating	to	the integration	of	the	two	companies.	Further,	the	pro	forma	data	should	not	be	considered	indicative	of	the	results	that	would	have	occurred	if	the	acquisition,	related financing	and	associated	notes	issuance	and	repayment	of	the	364-day	credit	facility	had	been	consummated	on	January	1,	2014,	nor	are	they	indicative	of	future	results.

We	paid	$898	million	in	2014	for	acquisitions	of	businesses	and	investments	in	affiliates,	net	of	cash	acquired,	primarily	related	to	the	acquisitions	of	Systems Made	Simple,	Zeta	and	Industrial	Defender.	On	December	1,	2014,	we	completed	 the	acquisition	of	all	 interests	 in	Systems	Made	Simple,	a	provider	of	health information	technology	solutions,	which	is	included	in	our	IS&GS	business	segment.	On	August	18,	2014,	we	completed	the	acquisition	of	all	interests	in	Zeta,	a designer	of	systems	that	enable	collection,	processing,	safeguarding	and	dissemination	of	information	for	intelligence	and	defense	communities,	which	is	included	in	our Space	Systems	business	segment.	On	April	7,	2014,	we	completed	the	acquisition	of	all	interest	in	Industrial	Defender,	a	provider	of	cybersecurity	solutions	for	control systems	in	the	oil	and	gas,	utility	and	chemical	industries,	which	is	included	in	our	IS&GS	business	segment.	In	connection	with	the	2014	acquisitions,	we	preliminarily recorded	goodwill	of	$657	million,	related	to	expected	synergies	from	combining	operations	and	value	of	the	existing	workforce.	The	recorded	goodwill	is	not	deductible for	tax	purposes.	Additionally,	we	recorded	other	intangible	assets	of	$223	million,	primarily	related	to	customer	relationships	and	technologies,	which	will	be	amortized over	a	weighted	average	period	of	eight	years.	We	plan	to	include	Systems	Made	Simple	and	Industrial	Defender	in	any	future	divestiture	of	our	IS&GS	business segment.

We	paid	$269	million	in	2013	for	acquisitions	of	businesses	and	investments	in	affiliates,	net	of	cash	acquired,	primarily	related	to	the	acquisition	of	Amor	Group,	a United	Kingdom-based	company	specializing	in	information	technology,	civil	government	services	and	the	energy	market.	Amor	Group	is	included	in	our	IS&GS business	segment.	In	connection	with	these	acquisitions,	we	recorded	goodwill	of	$175	million,	which	is	not	deductible	for	tax	purposes.	Additionally,	we	recorded	other intangible	assets	of	$34	million,	related	to	customer	relationships	and	technologies,	which	will	be	amortized	over	a	weighted	average	period	of	eight	years.

Systems	Made	Simple,	Industrial	Defender	and	Amor	Group	will	be	divested	as	part	of	the	IS&GS	business	segment	in	connection	with	the	proposed	transaction with	Leidos	(discussed	below).

# Divestitures

# IS&GS	Divestiture

On	January	26,	2016,	we	entered	into	definitive	agreements	to	separate	and	combine	our	IS&GS	business	segment	with	Leidos	in	a	tax-efficient	Reverse	Morris Trust	transaction.	As	part	of	the	transaction,	we	will	receive	a	$1.8	billion	one-time	special	cash	payment	.	The	cash	payment	is	subject	to	adjustment	and	could	be	less or	more	than	anticipated	due	to	variances	in	working	capital.	Additionally,	our	stockholders	will	receive	approximately	50.5	percent	of	the	outstanding	equity	of	Leidos on	a	fully	diluted	basis	(approximately	77	million	shares)	with	an	estimated	value	of	$3.2	billion	based	on	Leidos'	stock	price	on	the	date	of	announcement.	However, the	actual	value	of	the	stock	to	be	received	by	our	stockholders	will	depend	on	the	value	of	such	shares	at	the	time	of	closing	of	the	transaction	and	our	stockholders	may receive	more	or	less	than	the	anticipated	value.	At	our	election,	the	distribution	may	be	effected	by	means	of	a	pro	rata	dividend	in	a	spin-off	transaction	or	in	an exchange	 offer	 for	 outstanding	 Lockheed	 Martin	 shares	 in	 a	 split-off	 transaction.	 The	 transaction	 structure,	 which	 is	 subject	 to	 market	 conditions,	 is	 currently contemplated	to	be	a	split-off	transaction	resulting	in	a	decrease	in	our	outstanding	common	shares	and	a	significant	book	gain	at	closing.	In	a	split-off	transaction,	only those	stockholders	that	elect	to	participate	will	receive	Leidos	shares	in	the	merger	transaction,	provided,	that,	if	the	exchange	offer	is	not	fully	subscribed,	Lockheed Martin	will	spin-off	the	remaining	shares	to	be	converted	into	Leidos	stock	in	the	merger	pro	rata.	The	value	of	the	shares	of	Leidos	stock	to	be	received	and	the	value	of our	stock	at	the	time	of	the	split-off	will	also	impact	the	number	of	any	shares	of	our	stock	retired	in	the	split-off	and	the	amount	of	any	book	gain.	Although	the transaction	structure	is	currently	contemplated	to	be	a	split-off	transaction,	there	is	no	assurance	that	the	transaction	will	be	structured	as	a	split-off	transaction	or	that	it will	result	in	a	reduction	in	our	shares	or	a	gain	at	closing.

Subsequent	to	the	program	realignment	completed	in	the	fourth	quarter	of	2015,	the	IS&GS	business	segment	consists	solely	of	government	IT	and	technical services	businesses.	The	transaction	is	expected	to	close	in	the	third	or	fourth	quarter	of	2016.	Until	closing,	IS&GS	will	operate	as	a	business	segment	and	financial results	for	the	IS&GS	business	segment	will	be	reported	in	our	continuing	operations.

# Prior	Year	Divestiture

Discontinued	operations	for	2013	included	a	benefit	of	$31	million	resulting	from	the	resolution	of	certain	tax	matters	related	to	a	business	previously	sold	prior	to

Amortization	 expense	 for	 acquired	 finite-lived	 intangible	 assets	 was	 $116	 million,	 $49	 million	 and	 $48	 million	 in	 2015,	 2014	 and	 2013.	 Estimated	 future amortization	expense	is	as	follows:	$292	million	in	2016;	$274	million	in	2017;	$260	million	in	2018;	$254	million	in	2019;	$248	million	in	2020	and	$710	million thereafter.	Our	estimates	of	amortization	expense	for	finite-lived	intangible	assets	are	subject	to	change,	pending	the	final	determination	of	the	fair	value	of	intangible assets	acquired	in	connection	with	the	Sikorsky	acquisition	(See	Note	3).

# Note	5	–	Information	on	Business	Segments

During	the	fourth	quarter	of	2015,	we	realigned	certain	programs	among	our	business	segments	in	connection	with	the	strategic	review	of	our	government	IT	and technical	services	businesses.	As	part	of	the	realignment,	command,	control,	communications,	computers,	intelligence,	surveillance	and	reconnaissance	(C4ISR)	and government	cyber	programs	were	transferred	from	the	IS&GS	business	segment	to	the	MST	business	segment,	energy	solutions	programs	were	transferred	from	the IS&GS	business	segment	to	the	MFC	business	segment,	space	ground	station	programs	were	transferred	from	the	IS&GS	business	segment	to	Space	Systems	business segment,	and	substantially	all	technical	services	programs	were	transferred	from	the	MFC	business	segment	to	the	IS&GS	business	segment.	Subsequent	to	the	program realignment,	our	IS&GS	business	segment	which	we	plan	to	divest	in	the	third	or	fourth	quarter	of	2016	represents	the	government	IT	and	technical	services	businesses that	were	under	strategic	review.

The	amounts,	discussion	and	presentation	of	our	business	segments	as	set	forth	in	our	consolidated	financial	statements	have	been	reclassified	from	prior	year presentation	 to	 reflect	 the	 program	 realignment	 described	 above	 for	 all	 years	 presented.	 The	 realignment	 did	 not	 impact	 the	 Corporation's	 previously	 reported consolidated	financial	statements.

Following	is	a	brief	description	of	the	activities	of	our	business	segments:

•	 Aeronautics	–	Engaged	in	the	research,	design,	development,	manufacture,	integration,	sustainment,	support	and	upgrade	of	advanced	military	aircraft,	including combat	and	air	mobility	aircraft,	unmanned	air	vehicles	and	related	technologies.

•Information	Systems	&	Global	Solutions	–	Provides	advanced	technology	systems	and	expertise,	integrated	information	technology	solutions	and	management services	across	a	broad	spectrum	of	applications	for	civil,	defense,	intelligence	and	other	government	customers.	IS&GS'	technical	services	business	provides	a comprehensive	portfolio	of	technical	and	sustainment	services.

•	 Missiles	and	Fire	Control	–	Provides	air	and	missile	defense	systems;	tactical	missiles	and	air-to-ground	precision	strike	weapon	systems;	logistics;	fire	control systems;	mission	operations	support,	readiness,	engineering	support	and	integration	services;	manned	and	unmanned	ground	vehicles;	and	energy	management solutions.

•	 Mission	Systems	and	Training	–	Provides	design,	manufacture,	service	and	support	for	a	variety	of	military	and	civil	helicopters;	ship	and	submarine	mission	and combat	systems;	mission	systems	and	sensors	for	rotary	and	fixed-wing	aircraft;	sea	and	land-based	missile	defense	systems;	radar	systems;	the	Littoral	Combat	Ship; simulation	 and	 training	 services;	 and	 unmanned	 systems	 and	 technologies.	 In	 addition,	 MST	 supports	 the	 needs	 of	 customers	 in	 cybersecurity	 and	 delivers communications	and	command	and	control	capability	through	complex	mission	solutions	for	defense	applications.	The	results	of	the	acquired	Sikorsky	business	have been	included	in	our	consolidated	results	of	operations	from	the	November	6,	2015	acquisition	date	through	December	31,	2015.	Accordingly,	the	consolidated results	of	operations	for	the	year	ended	December	31,	2015	do	not	reflect	a	full	year	of	Sikorsky	operations.

•Space	Systems	–	Engaged	in	the	research	and	development,	design,	engineering	and	production	of	satellites,	strategic	and	defensive	missile	systems	and	space transportation	systems.	Space	systems	provides	network-enabled	situational	awareness	and	integrates	complex	global	systems	to	help	our	customers	gather,	analyze and	securely	distribute	critical	intelligence	data.	Space	Systems	is	also	responsible	for	various	classified	systems	and	services	in	support	of	vital	national	security systems.	Operating	profit	for	our	Space	Systems	business	segment	includes	our	share	of	earnings	for	our	investment	in	ULA,	which	provides	expendable	launch services	to	the	U.S.	Government.

The	financial	information	in	the	following	tables	includes	the	results	of	businesses	we	have	acquired	during	the	past	three	years	(Note	3)	from	their	respective	dates of	acquisition.	The	business	segment	operating	results	in	the	following	tables	exclude	businesses	included	in	discontinued	operations	(Note	3)	for	all	years	presented. Net	sales	of	our	business	segments	exclude	intersegment	sales	as	these	activities	are	eliminated	in	consolidation.

Operating	profit	of	our	business	segments	includes	our	share	of	earnings	or	losses	from	equity	method	investees	as	the	operating	activities	of	the	equity	method investees	are	closely	aligned	with	the	operations	of	our	business	segments.	United	Launch	Alliance	(ULA),	which	is	part	of	our	Space	Systems	business	segment,	is	our primary	equity	method	 investee.	Operating	profit	of	our	business	segments	excludes	 the	FAS/CAS	pension	adjustment	described	below;	expense	for	stock-based compensation;	the	effects	of	items	not	considered	part	of	management's	evaluation	of	segment	operating	performance,	such	as	charges	related	to	significant	severance actions	(Note	15)	and	goodwill	impairments;	gains	or	losses	from

divestitures;	the	effects	of	certain	legal	settlements;	corporate	costs	not	allocated	to	our	business	segments;	and	other	miscellaneous	corporate	activities.	These	items	are included	in	the	reconciling	item	"Unallocated	items"	between	operating	profit	from	our	business	segments	and	our	consolidated	operating	profit.	See	Note	1	(under	the caption	"Use	of	Estimates")	for	a	discussion	related	to	certain	factors	that	may	impact	the	comparability	of	net	sales	and	operating	profit	of	our	business	segments.

Our	business	segments'	results	of	operations	include	pension	expense	only	as	calculated	under	U.S.	Government	Cost	Accounting	Standards	(CAS),	which	we	refer to	as	CAS	pension	cost.	We	recover	CAS	pension	cost	through	the	pricing	of	our	products	and	services	on	U.S.	Government	contracts	and,	therefore,	the	CAS	pension cost	is	recognized	in	each	of	our	business	segments'	net	sales	and	cost	of	sales.	Since	our	consolidated	financial	statements	must	present	pension	expense	calculated	in accordance	with	the	financial	accounting	standards	(FAS)	requirements	under	GAAP,	which	we	refer	to	as	FAS	pension	expense,	the	FAS/CAS	pension	adjustment increases	or	decreases	the	CAS	pension	cost	recorded	in	our	business	segments'	results	of	operations	to	equal	the	FAS	pension	expense.

This	charge	was	partially	offset	by	a	net	deferred	tax	benefit	of	about	$80	million,	which	is	recorded	in	income	tax	expense.	The	net	impact	reduced	net earnings	by	about	$10	million.

State	income	taxes	are	included	in	our	operations	as	general	and	administrative	costs	and,	under	U.S.	Government	regulations,	are	allowable	costs	in	establishing prices	for	the	products	and	services	we	sell	to	the	U.S.	Government.	Therefore,	a	substantial	portion	of	state	income	taxes	is	included	in	our	net	sales	and	cost	of	sales. As	a	result,	the	impact	of	certain	transactions	on	our	operating	profit	and	of	other	matters	presented	in	these	financial	statements	is	disclosed	net	of	state	income	taxes. Our	total	net	state	income	tax	expense	was	$127	million	for	2015,	$207	million	for	2014,	and	$121	million	for	2013.

Our	reconciliation	of	the	35%	U.S.	federal	statutory	income	tax	rate	to	actual	income	tax	expense	for	continuing	operations	is	as	follows	(in	millions):

We	recognized	tax	benefits	of	$71	million	in	2015,	$66	million	in	2014,	and	$96	million	in	2013	from	U.S.	research	and	development	(R&D)	tax	credits,	including benefits	attributable	to	prior	periods.	In	2015,	the	R&D	tax	credit	was	permanently	extended	and	reinstated,	retroactive	to	the	beginning	of	2015,	which	reduced	income tax	expenses	by	approximately	$71	million.	In	2014,	the	R&D	tax	credit	was	temporarily	reinstated	for	one	year,	retroactive	to	the	beginning

of	2014,	which	reduced	income	tax	expense	by	approximately	$45	million.	In	2013,	the	R&D	tax	credit	was	temporarily	reinstated	for	two	years,	retroactive	to	the beginning	of	2012.	As	a	result,	income	tax	expense	for	2013	reflects	the	credit	for	all	of	2013	and	2012,	which	reduced	income	tax	expense	by	approximately	$76 million.

We	receive	a	tax	deduction	for	dividends	paid	on	shares	of	our	common	stock	held	by	certain	of	our	defined	contribution	plans	with	an	employee	stock	ownership plan	feature.	The	amount	of	the	tax	deduction	has	increased	as	we	increased	our	dividend	over	the	last	three	years,	partially	offset	by	a	decline	in	the	number	of	shares	in these	plans.

A	limited	amount	of	the	2014	and	2013	non-cash	goodwill	impairment	charges	will	be	deductible	for	tax	purposes.	Accordingly,	the	2014	and	2013	non-cash goodwill	impairment	charges	(Note	1)	of	$119	million	and	$195	million,	respectively,	increased	our	2014	and	2013	effective	tax	rates.

As	a	result	of	a	decision	in	2015	to	divest	Lockheed	Martin	Commercial	Flight	Training	in	2016,	we	recorded	an	asset	impairment	charge	of	approximately	$90 million.	This	charge	was	partially	offset	by	a	net	deferred	tax	benefit	of	about	$80	million.	The	net	impact	of	the	resulting	tax	benefit	reduced	the	effective	income	tax rate	by	1.0	percentage	point	in	2015.

We	participate	in	the	IRS	Compliance	Assurance	Process	program.	The	IRS	examination	of	the	year	2012	was	completed	in	the	fourth	quarter	of	2013.	The examinations	of	the	years	2013	and	2014	remain	under	review.

The	primary	components	of	our	federal	and	foreign	deferred	income	tax	assets	and	liabilities	at	December	31	were	as	follows	(in	millions):

| Net\tdeferred\ttax\tassets\t(d) | $5,925 | $5,452 |

(a) The	increase	in	2015	was	primarily	due	to	the	negative	investment	return	on	postretirement	plan	assets	(Note	11).

(b) A	valuation	allowance	was	provided	against	certain	foreign	company	deferred	tax	assets	arising	from	carryforwards	of	unused	tax	benefits.

(c) Includes	deferred	taxes	associated	with	the	exchange	of	debt	securities	in	prior	years.

(d) Includes	net	foreign	current	deferred	tax	liabilities,	which	are	included	on	the	Balance	Sheets	in	other	current	liabilities.

As	of	December	31,	2015	and	2014,	our	liabilities	associated	with	unrecognized	tax	benefits	are	not	material.

We	and	our	subsidiaries	file	income	tax	returns	in	the	U.S.	federal	jurisdiction	and	various	foreign	jurisdictions.	With	few	exceptions,	the	statute	of	limitations	is	no longer	open	for	U.S.	federal	or	non-U.S.	income	tax	examinations	for	the	years	before	2012,	other	than	with	respect	to	refunds.

U.S.	income	taxes	and	foreign	withholding	taxes	have	not	been	provided	on	earnings	of	$353	million,	$291	million,	and	$222	million	that	have	not	been	distributed by	our	non-U.S.	companies	as	of	December	31,	2015,	2014,	and	2013.	Our	intention	is	to	permanently	reinvest	these	earnings,	thereby	indefinitely	postponing	their remittance	to	the	U.S.	If	these	earnings	had	been	remitted,	we	estimate	that	the	additional	income	taxes	after	foreign	tax	credits	would	have	been	approximately	$48 million	in	2015,	$55	million	in	2014,	and	$50	million	in	2013.

Our	federal	and	foreign	income	tax	payments,	net	of	refunds	received,	were	$1.8	billion	in	2015,	$1.5	billion	in	2014,	and	$787	million	in	2013.	Our	2014	net payments	reflect	a	$200	million	refund	from	the	IRS	primarily	attributable	to	our	tax-deductible	discretionary	pension	contributions	during	the	fourth	quarters	of	2013.

Our	long-term	debt	consisted	of	the	following	(in	millions):

On	October	9,	2015,	we	entered	into	a	new	$2.5	billion	revolving	credit	facility	(the	5-year	Facility)	with	various	banks	and	concurrently	terminated	our	existing $1.5	billion	revolving	credit	facility,	which	was	scheduled	to	expire	in	August	2019.	The	5-year	Facility,	which	expires	on	October	9,	2020,	is	available	for	general corporate	purposes.	The	undrawn	portion	of	the	5-year	Facility	is	also	available	to	serve	as	a	backup	facility	for	the	issuance	of	commercial	paper.	We	may	request	and the	banks	may	grant,	at	their	discretion,	an	increase	in	the	borrowing	capacity	under	the	5-year	Facility	of	up	to	an	additional	$500	million.	There	were	no	borrowings outstanding	under	the	5-year	Facility	as	of	and	during	the	year	ended	December	31,	2015.

In	contemplation	of	our	acquisition	of	Sikorsky,	on	October	9,	2015,	we	also	entered	into	a	364-day	revolving	credit	facility	(the	364-day	Facility,	and	together	with the	5-year	Facility,	the	Facilities)	with	various	banks	that	provided	$7.0	billion	of	funding	for	general	corporate	purposes,	including	the	acquisition	of	Sikorsky. Concurrent	with	the	consummation	of	the	Sikorsky	acquisition,	we	borrowed	$6.0	billion	under	the	364-day	Facility.	On	November	23,	2015,	we	repaid	all	outstanding borrowings	under	the	364-day	facility	with	proceeds	received	from	an	issuance	of	new	debt	(see	below)	and	terminated	any	remaining	commitments	of	the	lenders	under the	364-day	Facility.

Borrowings	under	the	Facilities	bear	interest	at	rates	based,	at	our	option,	on	a	Eurodollar	Rate	or	a	Base	Rate,	as	defined	in	the	Facilities'	agreements.	Each	bank's obligation	to	make	loans	under	the	5-year	Facility	is	subject	to,	among	other	things,	our	compliance	with	various	representations,	warranties,	and	covenants,	including covenants	limiting	our	ability	and	certain	of	our	subsidiaries'	ability	to	encumber	assets	and	a	covenant	not	to	exceed	a	maximum	leverage	ratio,	as	defined	in	the	Five- year	Facility	agreement.	As	of	December	31,	2015,	we	were	in	compliance	with	all	covenants	contained	in	the	5-year	Facility	agreement,	as	well	as	in	our	debt agreements.

We	may,	at	our	option,	redeem	some	or	all	of	the	November	2015	Notes	and	unpaid	interest	at	any	time	by	paying	the	principal	amount	of	notes	being	redeemed plus	any	make-whole	premium	and	accrued	and	unpaid	interest	to	the	date	of	redemption.	Interest	is	payable	on	the	2018	Notes	and	the	2020	Notes	on	May	23	and November	23	of	each	year,	beginning	on	May	23,	2016;	on	the	2023	Notes	and	the	2026	Notes	on	January	15	and	July	15	of	each	year,	beginning	on	July	15,	2016;	and on	the	2036	Notes	and	the	2046	Notes	on	May	15	and	November	15	of	each	year,	beginning	on	May	15,	2016.	The	November	2015	Notes	rank	equally	in	right	of payment	with	all	of	our	existing	unsecured	and	unsubordinated	indebtedness.	The	proceeds	of	the	November	2015	Notes	were	used	to	repay	$6.0	billion	of	borrowings under	our	364-day	Facility	and	for	general	corporate	purposes.

We	have	agreements	in	place	with	financial	institutions	to	provide	for	the	issuance	of	commercial	paper.	In	connection	with	the	Sikorsky	acquisition,	in	the	fourth quarter	of	2015	we	borrowed	and	repaid	approximately	$1.0	billion	under	our	commercial	paper	programs.	There	were	no	commercial	paper	borrowings	outstanding	as of	December	31,	2015.	If	we	were	to	issue	commercial	paper	in	the	future,	the	borrowings	would	be	supported	by	the	credit	facility.

# Note	11	–	Postretirement	Plans

# Defined	Benefit	Pension	Plans	and	Retiree	Medical	and	Life	Insurance	Plans

Many	of	our	employees	are	covered	by	qualified	defined	benefit	pension	plans	and	we	provide	certain	health	care	and	life	insurance	benefits	to	eligible	retirees (collectively,	postretirement	benefit	plans).	We	also	sponsor	nonqualified	defined	benefit	pension	plans	to	provide	for	benefits	in	excess	of	qualified	plan	limits.	Non- union	employees	hired	after	December	2005	do	not	participate	in	our	qualified	defined	benefit	pension	plans,	but	are	eligible	to	participate	in	a	qualified	defined contribution	plan	in	addition	to	our	other	retirement	savings	plans.	They	also	have	the	ability	to	participate	in	our	retiree	medical	plans,	but	we	do	not	subsidize	the	cost of	their	participation	in	those	plans	as	we	do	with	employees	hired	before	January	1,	2006.	Over	the	last	few	years,	we	have	negotiated	similar	changes	with	various labor	organizations	such	that	new	union	represented	employees	do	not	participate	in	our	defined	benefit	pension	plans.	In	June	2014,	we	amended	certain	of	our qualified	and	nonqualified	defined	benefit	pension	plans	for	non-union	employees	to	freeze	future	retirement	benefits.	The	calculation	of	retirement	benefits	under	the affected	defined	benefit	pension	plans	is	determined	by	a	formula	that	takes	into	account	the	participants'	years	of	credited	service	and	average	compensation.	The freeze	will	take	effect	in	two	stages.	Beginning	on	January	1,	2016,	the	pay-based	component	of	the	formula	used	to	determine	retirement	benefits	is	frozen	so	that	future pay	increases,	annual	incentive	bonuses	or	other	amounts	earned	for	or	related	to	periods	after	December	31,	2015	are	not	used	to	calculate	retirement	benefits.	On January	1,	2020,	the	service-based	component	of	the	formula	used	to	determine	retirement	benefits	will	also	be	frozen	so	that	participants	will	no	longer	earn	further credited	service	for	any	period	after	December	31,	2019.	When	the	freeze	is	complete,	the	majority	of	our	salaried	employees	will	have	transitioned	to	an	enhanced defined	contribution	retirement	savings	plan.	As	part	of	the	November	6,	2015	acquisition	of	Sikorsky,	we	established	a	new	open	defined	benefit	pension	plan	for Sikorsky's	union	workforce	that	provides	benefits	for	their	prospective	service	with	us.	The	Sikorsky	salaried	employees	participate	in	a	defined	contribution	plan.	We did	not	transfer	any	legacy	pension	liability	from	UTC.

We	have	made	contributions	to	trusts	established	to	pay	future	benefits	to	eligible	retirees	and	dependents,	including	Voluntary	Employees'	Beneficiary	Association trusts	and	401(h)	accounts,	the	assets	of	which	will	be	used	to	pay	expenses	of	certain	retiree	medical	plans.	We	use	December	31	as	the	measurement	date.	Benefit obligations	as	of	the	end	of	each	year	reflect	assumptions	in	effect	as	of	those	dates.	Net	periodic	benefit	cost	is	based	on	assumptions	in	effect	at	the	end	of	the respective	preceding	year.

The	rules	related	to	accounting	for	postretirement	benefit	plans	under	GAAP	require	us	to	recognize	on	a	plan-by-plan	basis	the	funded	status	of	our	postretirement benefit	plans	as	either	an	asset	or	a	liability	on	our	Balance	Sheets.	There	is	a	corresponding	non-cash	adjustment	to	accumulated	other	comprehensive	loss,	net	of	tax benefits	recorded	as	deferred	tax	assets,	in	stockholders'	equity.	The	funded	status	is	measured	as	the	difference	between	the	fair	value	of	the	plan's	assets	and	the benefit	obligation	of	the	plan.

The	net	periodic	benefit	cost	recognized	each	year	included	the	following	(in	millions):

(a) Total	net	periodic	benefit	cost	associated	with	our	qualified	defined	benefit	plans	represents	pension	expense	calculated	in	accordance	with	GAAP	(FAS	pension	expense).	We are	required	to	calculate	pension	expense	in	accordance	with	both	GAAP	and	CAS	rules,	each	of	which	results	in	a	different	calculated	amount	of	pension	expense.	The	CAS pension	cost	is	recovered	through	the	pricing	of	our	products	and	services	on	U.S.	Government	contracts	and,	therefore,	is	recognized	in	net	sales	and	cost	of	sales	for	products and	services.	We	include	the	difference	between	FAS	pension	expense	and	CAS	pension	cost,	referred	to	as	the	FAS/CAS	pension	adjustment,	as	a	component	of	other unallocated,	net	on	our	Statements	of	Earnings.	The	FAS/CAS	pension	adjustment,	which	was	income	of	$471	million	in	2015;	income	of	$376	million	in	2014;	and	expense	of $482	million	in	2013,	effectively	adjusts	the	amount	of	CAS	pension	cost	in	the	business	segment	operating	profit	so	that	pension	expense	recorded	on	our	Statements	of Earnings	is	equal	to	FAS	pension	expense.

The	following	table	provides	a	reconciliation	of	benefit	obligations,	plan	assets	and	unfunded	status	related	to	our	qualified	defined	benefit	pension	plans	and	our retiree	medical	and	life	insurance	plans	(in	millions):

(a) Benefits	paid	 in	2014	for	qualified	defined	benefit	pension	plans	 include	$427	million	 in	 the	form	of	 lump-sum	settlement	payments	 to	former	employees	who	had	not commenced	receiving	their	vested	benefit	payments.	The	corresponding	benefit	obligation	that	was	released	was	$529	million.	The	settlement	payments	had	no	impact	on	our 2014	FAS	pension	expense	and	CAS	pension	cost.

(b) The	June	2014	plan	amendment	which	resulted	in	freezing	the	pay-based	component	of	the	formula	used	to	determine	retirement	benefits	under	the	affected	plans	reduced	our qualified	defined	benefit	pension	obligations	by	$4.6	billion,	which	resulted	in	a	corresponding	reduction,	net	of	tax,	in	the	accumulated	other	comprehensive	loss	(AOCL) component	of	stockholders'	equity.	This	amount	is	being	recognized	as	a	reduction	of	net	periodic	benefit	cost	(i.e.,	amortization	of	net	prior	service	credit)	over	the	estimated remaining	service	period	of	the	covered	employees,	which	is	approximately	10	years	and	began	in	the	third	quarter	of	2014.	The	November	2015	acquisition	of	Sikorsky increased	our	qualified	defined	benefit	pension	obligations	by	about	$30	million.

The	following	table	provides	amounts	recognized	on	our	Balance	Sheets	related	to	our	qualified	defined	benefit	pension	plans	and	our	retiree	medical	and	life insurance	plans	(in	millions):

(a) Accumulated	other	comprehensive	loss	related	to	postretirement	benefit	plans,	after	tax,	of	$11.3	billion	and	$11.8	billion	at	December	31,	2015	and	2014	(Note	12)	includes $16.1	billion	($10.4	billion	after	tax)	and	$16.8	billion	($10.8	billion	after	tax)	for	qualified	defined	benefit	pension	plans,	$794	million	($514	million	after	tax)	and	$755	million ($488	million	after	tax)	for	retiree	medical	and	life	insurance	plans	and	$620	million	($408	million	after	tax)	and	$692	million	($460	million	after	tax)	for	other	plans.

The	accumulated	benefit	obligation	(ABO)	for	all	qualified	defined	benefit	pension	plans	was	$43.5	billion	and	$45.2	billion	at	December	31,	2015	and	2014,	of which	$43.4	billion	and	$45.0	billion	related	to	plans	where	the	ABO	was	in	excess	of	plan	assets.	The	ABO	represents	benefits	accrued	without	assuming	future compensation	increases	to	plan	participants.	Certain	key	information	related	to	our	qualified	defined	benefit	pension	plans	as	of	December	31,	2015	and	2014	is	as follows	(in	millions):

(b) Represent	prepaid	pension	assets,	which	are	included	on	our	Balance	Sheets	in	other	noncurrent	assets.

We	also	sponsor	nonqualified	defined	benefit	plans	to	provide	benefits	in	excess	of	qualified	plan	limits.	The	aggregate	liabilities	for	these	plans	at	December	31, 2015	and	2014	were	$1.2	billion	and	$1.1	billion,	which	also	represent	the	plans'	unfunded	status.	We	have	set	aside	certain	assets	totaling	$421	million	and	$397 million	as	of	December	31,	2015	and	2014	in	a	separate	trust	which	we	expect	to	be	used	to	pay	obligations	under	our	nonqualified	defined	benefit	plans.	In	accordance with	GAAP,	those	assets	may	not	be	used	to	offset	the	amount	of	the	benefit	obligation	similar	to	the	postretirement	benefit	plans	in	the	table	above.	The	unrecognized net	actuarial	losses	at	December	31,	2015	and	2014	were	$632	million	and	$662	million.	The	unrecognized	prior	service	credit	at	December	31,	2015	was	$95	million and	was	$121	million	at	December	31,	2014.	The	expense	associated	with	these	plans	totaled	$117	million	in	2015,	$115	million	in	2014	and	$108	million	in	2013.	We also	sponsor	a	small	number	of	other	postemployment	plans	and	foreign	benefit	plans.	The	aggregate	liability	for	the	other	postemployment	plans	was	$70	million	and $88	million	as	of	December	31,	2015	and	2014.	The	expense	for	the	other	postemployment	plans,	as	well	as	the	liability	and	expense	associated	with	the	foreign	benefit plans,	was	not	material	to	our	results	of	operations,	financial	position	or	cash	flows.	The	actuarial	assumptions	used	to	determine	the	benefit	obligations	and	expense associated	with	our	nonqualified	defined	benefit	plans	and	postemployment	plans	are	similar	to	those	assumptions	used	to	determine	the	benefit	obligations	and	expense related	to	our	qualified	defined	benefit	pension	plans	and	retiree	medical	and	life	insurance	plans	as	described	below.

The	following	table	provides	the	amounts	recognized	in	other	comprehensive	income	(loss)	related	to	postretirement	benefit	plans,	net	of	tax,	for	the	years	ended December	31,	2015,	2014	and	2013	(in	millions):

We	expect	that	approximately	$1.1	billion,	or	about	$693	million	net	of	tax,	of	actuarial	losses	and	net	prior	service	credit	related	to	postretirement	benefit	plans included	in	accumulated	other	comprehensive	loss	at	the	end	of	2015	to	be	recognized	in	net	periodic	benefit	cost	during	2016.	Of	this	amount,	$1.0	billion,	or	$629 million	net	of	tax,	relates	to	our	qualified	defined	benefit	plans	and	is	included	in	our	expected	2016	pension	expense	of	$1.0	billion.

The	actuarial	assumptions	used	to	determine	the	benefit	obligations	at	December	31	of	each	year	and	to	determine	the	net	periodic	benefit	cost	for	each	subsequent year,	were	as	follows:

The	increase	in	the	discount	rate	from	December	31,	2014	to	December	31,	2015	resulted	in	a	decrease	in	the	projected	benefit	obligations	of	our	qualified	defined benefit	pension	plans	of	approximately	$2.1	billion	at	December	31,	2015.	The	decrease	in	the	discount	rate	from	December	31,	2013	to	December	31,	2014	resulted	in an	increase	in	the	projected	benefit	obligations	of	our	qualified	defined	benefit	pension	plans	of	approximately	$4.8	billion	at	December	31,	2014.

The	long-term	rate	of	return	assumption	represents	the	expected	long-term	rate	of	earnings	on	the	funds	invested,	or	to	be	invested,	to	provide	for	the	benefits included	in	the	benefit	obligations.	That	assumption	is	based	on	several	factors	including	historical	market	index	returns,	the	anticipated	long-term	allocation	of	plan assets,	the	historical	return	data	for	the	trust	funds,	plan	expenses	and	the	potential	to	outperform	market	index	returns.

# Plan	Assets

Investment	 policies	 and strategies	 –	 Lockheed	 Martin	 Investment	 Management	 Company	 (LMIMCo),	 our	 wholly-owned	 subsidiary,	 has	 the	 fiduciary responsibility	for	making	investment	decisions	related	to	the	assets	of	our	postretirement	benefit	plans.	LMIMCo's	investment	objectives	for	the	assets	of	these	plans	are (1)	to	minimize	the	net	present	value	of

expected	funding	contributions;	(2)	to	ensure	there	is	a	high	probability	that	each	plan	meets	or	exceeds	our	actuarial	long-term	rate	of	return	assumptions;	and	(3)	to diversify	assets	to	minimize	the	risk	of	large	losses.	The	nature	and	duration	of	benefit	obligations,	along	with	assumptions	concerning	asset	class	returns	and	return correlations,	are	considered	when	determining	an	appropriate	asset	allocation	to	achieve	the	investment	objectives.

Investment	policies	and	strategies	governing	the	assets	of	the	plans	are	designed	to	achieve	investment	objectives	within	prudent	risk	parameters.	Risk	management practices	include	the	use	of	external	investment	managers;	the	maintenance	of	a	portfolio	diversified	by	asset	class,	investment	approach	and	security	holdings;	and	the maintenance	of	sufficient	liquidity	to	meet	benefit	obligations	as	they	come	due.

LMIMCo's	investment	policies	require	that	asset	allocations	of	postretirement	benefit	plans	be	maintained	within	the	following	approximate	ranges:

|  | Asset	Allocation |
| :--- | :--- |
| Asset\tClass | Ranges |
| Cash\tand\tcash\tequivalents | \t\t0-20% |
| Equity | 15-65% |

| Commodities | \t\t0-25% |

Fair	value	measurements	 –	The rules	 related	 to	 accounting	 for	 postretirement	 benefit	 plans	 under	 GAAP	 require	 certain	 fair	 value	 disclosures	 related	 to postretirement	benefit	plan	assets,	even	though	those	assets	are	not	included	on	our	Balance	Sheets.	The	following	table	presents	the	fair	value	of	the	assets	(in	millions) of	our	qualified	defined	benefit	pension	plans	and	retiree	medical	and	life	insurance	plans	by	asset	category	and	their	level	within	the	fair	value	hierarchy,	which	has three	levels	based	on	the	reliability	of	the	inputs	used	to	determine	fair	value.	Level	1	refers	to	fair	values	determined	based	on	quoted	prices	in	active	markets	for identical	assets,	Level	2	refers	to	fair	values	estimated	using	significant	other	observable	inputs	and	Level	3	includes	fair	values	estimated	using	significant	unobservable inputs.

LMIMCO's	investment	policies	restrict	the	use	of	derivatives	to	either	establish	long	exposures	for	purposes	of	expediency	or	capital	efficiency	or to	hedge	risks	to	the	extent	of	a	plan's	current	exposure	to	such	risks.	Most	derivative	transactions	are	settled	on	a	daily	basis.

Valuation	techniques	–	Cash	equivalents	are	mostly	comprised	of	short-term	money-market	instruments	and	are	valued	at	cost,	which	approximates	fair	value.

U.S.	equity	securities	and	international	equity	securities	categorized	as	Level	1	are	traded	on	active	national	and	international	exchanges	and	are	valued	at	their closing	prices	on	the	last	trading	day	of	the	year.	For	U.S.	equity	securities	and	international	equity	securities	not	traded	on	an	active	exchange,	or	if	the	closing	price	is not	available,	the	trustee	obtains	indicative	quotes	from	a	pricing	vendor,	broker	or	investment	manager.	These	securities	are	categorized	as	Level	2	if	the	custodian obtains	corroborated	quotes	from	a	pricing	vendor	or	categorized	as	Level	3	if	the	custodian	obtains	uncorroborated	quotes	from	a	broker	or	investment	manager.

Commingled	equity	funds	are	investment	vehicles	valued	using	the	Net	Asset	Value	(NAV)	provided	by	the	fund	managers.	The	NAV	is	the	total	value	of	the	fund divided	by	the	number	of	shares	outstanding.	Commingled	equity	funds	are	categorized	as	Level	1	if	traded	at	their	NAV	on	a	nationally	recognized	securities	exchange or	categorized	as	Level	2	if	the	NAV	is	corroborated	by	observable	market	data	(e.g.,	purchases	or	sales	activity)	and	we	are	able	to	redeem	our	investment	in	the	near- term.

Fixed	income	investments	categorized	as	Level	2	are	valued	by	the	trustee	using	pricing	models	that	use	verifiable	observable	market	data	(e.g.,	interest	rates	and yield	curves	observable	at	commonly	quoted	intervals	and	credit	spreads),	bids	provided	by	brokers	or	dealers	or	quoted	prices	of	securities	with	similar	characteristics. Fixed	income	investments	are	categorized	at	Level	3	when	valuations	using	observable	inputs	are	unavailable.	The	trustee	obtains	pricing	based	on	indicative	quotes	or bid	evaluations	from	vendors,	brokers	or	the	investment	manager.

Private	equity	funds,	real	estate	funds	and	hedge	funds	are	valued	using	the	NAV	based	on	valuation	models	of	underlying	securities	which	generally	include significant	unobservable	inputs	that	cannot	be	corroborated	using	verifiable	observable	market	data.	Valuations	for	private	equity	funds	and	real	estate	funds	are determined	by	the	general	partners.	Depending	on	the	nature	of	the	assets,	the	general	partners	may	use	various	valuation	methodologies,	including	the	income	and market	approaches	in	their	models.	The	market	approach	consists	of	analyzing	market	transactions	for	comparable	assets	while	the	income	approach	uses	earnings	or	the net	present	value	of	estimated	future	cash	flows	adjusted	for	liquidity	and	other	risk	factors.	Hedge	funds	are	valued	by	independent	administrators	using	various	pricing sources	and	models	based	on	the	nature	of	the	securities.	Private	equity	funds,	real	estate	funds	and	hedge	funds	are	generally	categorized	as	Level	3	as	we	cannot	fully redeem	our	investment	in	the	near-term.

Commodities	are	traded	on	an	active	commodity	exchange	and	are	valued	at	their	closing	prices	on	the	last	trading	day	of	the	year.

# Contributions	and	Expected	Benefit	Payments

The	funding	of	our	qualified	defined	benefit	pension	plans	is	determined	in	accordance	with	ERISA,	as	amended	by	the	PPA,	and	in	a	manner	consistent	with	CAS and	Internal	Revenue	Code	rules.	In	2015,	we	made	$5	million	in	contributions	to	our	new	Sikorsky	bargained	qualified	defined	benefit	pension	plan	and	we	plan	to make	approximately	$25	million	in	contributions	to	this	plan	in	2016.

The	following	table	presents	estimated	future	benefit	payments,	which	reflect	expected	future	employee	service,	as	of	December	31,	2015	(in	millions):

# Defined	Contribution	Plans

We	maintain	a	number	of	defined	contribution	plans,	most	with	401(k)	features,	that	cover	substantially	all	of	our	employees.	Under	the	provisions	of	our	401(k) plans,	we	match	most	employees'	eligible	contributions	at	rates	specified	in	the	plan	documents.	Our	contributions	were	$393	million	in	2015,	$385	million	in	2014	and $383	million	in	2013,	the	majority	of	which	were	funded	in	our	common	stock.	Our	defined	contribution	plans	held	approximately	40.0	million	and	41.7	million	shares of	our	common	stock	as	of	December	31,	2015	and	2014.

# Note	12	–	Stockholders'	Equity

At	December	31,	2015	and	2014,	our	authorized	capital	was	composed	of	1.5	billion	shares	of	common	stock	and	50	million	shares	of	series	preferred	stock.	Of	the 305	million	shares	of	common	stock	issued	and	outstanding	as	of	December	31,	2015,	303	million	shares	were	considered	outstanding	for	Balance	Sheet	presentation purposes;	the	remaining	shares	were	held	in	a	separate	trust.	Of	the	316	million	shares	of	common	stock	issued	and	outstanding	as	of	December	31,	2014,	314	million shares	were	considered	outstanding	for	Balance	Sheet	presentation	purposes;	the	remaining	shares	were	held	in	a	separate	trust.	No	shares	of	preferred	stock	were	issued and	outstanding	at	December	31,	2015	or	2014.

# Repurchases	of	Common	Stock

On	September	24,	2015,	our	Board	of	Directors	approved	a	$3.0	billion	increase	to	our	share	repurchase	program.	Inclusive	of	this	increase,	the	total	remaining authorization	for	future	common	share	repurchases	under	our	program	was	$3.6	billion	as	of	December	31,	2015.	As	we	repurchase	our	common	shares,	we	reduce common	stock	for	the	$1	of	par	value	of	the	shares	repurchased,	with	the	excess	purchase	price	over	par	value	recorded	as	a	reduction	of	additional	paid-in	capital.	Due to	the	volume	of	repurchases	made	under	our	share	repurchase	program,	additional	paid-in	capital	was	reduced	to	zero,	with	the	remainder	of	the	excess	purchase	price over	par	value	of	$2.4	billion	and	$1.1	billion	recorded	as	a	reduction	of	retained	earnings	in	2015	and	2014.

(a) AOCL	related	to	postretirement	benefit	plans	is	shown	net	of	tax	benefits	at	December	31,	2015,	2014	and	2013	of	$6.2	billion,	$6.4	billion	and	$5.3	billion.	These	tax	benefits include	amounts	recognized	on	our	income	tax	returns	as	current	deductions	and	deferred	income	taxes,	which	will	be	recognized	on	our	tax	returns	in	future	years.	See	Note	9 and	Note	11	for	more	information	on	our	income	taxes	and	postretirement	benefit	plans.

# Note	13	–	Stock-Based	Compensation

During	2015,	2014	and	2013,	we	recorded	non-cash	stock-based	compensation	expense	totaling	$138	million,	$164	million	and	$189	million,	which	is	included	as a	component	of	other	unallocated,	net	on	our	Statements	of	Earnings.	The	net	impact	to	earnings	for	the	respective	years	was	$90	million,	$107	million	and	$122	million.

As	of	December	31,	2015,	we	had	$79	million	of	unrecognized	compensation	cost	related	to	nonvested	awards,	which	is	expected	to	be	recognized	over	a	weighted average	period	of	1.7	years.	We	received	cash	from	the	exercise	of	stock	options	totaling	$174	million,	$308	million	and	$827	million	during	2015,	2014	and	2013.	In addition,	our	income	tax	liabilities	for	2015,	2014	and	2013	were	reduced	by	$213	million,	$215	million,	$158	million	due	to	recognized	tax	benefits	on	stock-based compensation	arrangements.

# Stock-Based	Compensation	Plans

Under	plans	approved	by	our	stockholders,	we	are	authorized	to	grant	key	employees	stock-based	incentive	awards,	including	options	to	purchase	common	stock, stock	appreciation	rights,	restricted	stock	units	(RSUs),	performance	stock	units	(PSUs)	or	other	stock	units.	The	exercise	price	of	options	to	purchase	common	stock may	not	be	less	than	the	fair	market	value	of	our	stock	on	the	date	of	grant.	No	award	of	stock	options	may	become	fully	vested	prior	to	the	third	anniversary	of	the grant	and	no	portion	of	a	stock	option	grant	may	become	vested	in	less	than	one	year.	The	minimum	vesting	period	for	restricted	stock	or	stock	units	payable	in	stock	is three	years.	Award	agreements	may	provide	for	shorter	or	pro-rated	vesting	periods	or	vesting	following	termination	of	employment	in	the	case	of	death,	disability, divestiture,	retirement,	change	of	control	or	layoff.	The	maximum	term	of	a	stock	option	or	any	other	award	is	10	years.

At	December	31,	2015,	inclusive	of	the	shares	reserved	for	outstanding	stock	options,	RSUs	and	PSUs,	we	had	approximately	15	million	shares	reserved	for issuance	under	the	plans.	At	December	31,	2015,	approximately	7	million	of	the	shares	reserved	for	issuance	remained	available	for	grant	under	our	stock-based compensation	plans.	We	issue	new	shares	upon	the	exercise	of	stock	options	or	when	restrictions	on	RSUs	and	PSUs	have	been	satisfied.

The	following	table	summarizes	activity	related	to	nonvested	RSUs	during	2015:

|  | Number | Weighted	Average |
| :--- | :--- | :--- |
|  | of\tRSUs | Grant-Date\tFair |
|  | (In\tthousands) | Value\tPer\tShare |
| Nonvested\tat\tDecember\t31,\t2012 | \t4,822 | $\t\t\t\t79.10 |

| Nonvested\tat\tDecember\t31,\t2013 | 3,859 | $\t\t\t\t82.42 |

| Vested | (2,194) | 87.66 |
| Forfeited | \t\t\t\t\t(84) | 91.11 |

| Vested | (1,642) | 103.30 |
| Forfeited | \t\t\t\t\t(43) | 132.28 |
| Nonvested\tat\tDecember\t31,\t2015 | \t1,236 | $\t\t134.87 |

In	January	2015,	we	granted	certain	employees	approximately	0.6	million	restricted	stock	units	(RSUs)	with	a	grant-date	fair	value	of	$192.28	per	RSU.	The	grant- date	fair	value	of	these	RSUs	is	equal	to	the	closing	market	price	of	our	common	stock	on	the	grant	date	less	a	discount	to	reflect	the	delay	in	payment	of	dividend- equivalent	cash	payments	that	are	made	only	upon	vesting,	which	is	generally	three	years	from	the	grant	date.	We	recognize	the	grant-date	fair	value	of	RSUs,	less estimated	forfeitures,	as	compensation	expense	ratably	over	the	requisite	service	period,	which	is	shorter	than	the	vesting	period	if	the	employee	is	retirement	eligible	on the	date	of	grant	or	will	become	retirement	eligible	before	the	end	of	the	vesting	period.

# Stock	Options

We	generally	recognize	compensation	cost	for	stock	options	ratably	over	the	three-year	vesting	period.	At	December	31,	2015	and	2014,	there	were	4.2	million (weighted	average	exercise	price	of	$86.61)	and	6.3	million	(weighted	average	exercise	price	of	$84.62)	stock	options	outstanding.	Stock	options	outstanding	at December	31,	2015	have	a	weighted	average	remaining	contractual	life	of	approximately	four	years	and	an	aggregate	intrinsic	value	of	$544	million.	Of	the	stock options	outstanding,	4.2	million	(weighted	average	exercise	price	of	$86.61)	have	vested	as	of	December	31,	2015	and	those	stock	options	have	a	weighted	average remaining	contractual	life	of	approximately	four	years	and	an	aggregate	intrinsic	value	of	$544	million.	There	were	2.2	million	(weighted	average	exercise	price	of $80.77)	stock	options	exercised	during	2015.	We	did	not	grant	stock	options	to	employees	during	2015	and	2014.

The	following	table	pertains	to	stock	options	granted	in	2012,	in	addition	to	stock	options	that	vested	and	were	exercised	in	2015,	2014	and	2013	(in	millions, except	for	weighted-average	grant-date	fair	value	of	stock	options	granted):

|  | 2015 | 2014 | 2013 |
| :--- | :--- | :--- | :--- |
| Weighted\taverage\tgrant-date\tfair\tvalue\tof\tstock\toptions\tgranted | $ — | $ — | $ — |
| Grant-date\tfair\tvalue\tof\tall\tstock\toptions\tthat\tvested | 8 | 18 | 40 |
| Intrinsic\tvalue\tof\tall\tstock\toptions\texercised | \t 265 | \t 297 | \t 293 |

In	2012,	we	estimated	the	fair	value	for	stock	options	at	the	date	of	grant	using	the	Black-Scholes	option	pricing	model,	which	required	us	to	make	certain assumptions.	We	used	the	following	weighted	average	assumptions	in	the	model:	risk-free	interest	rate	of	0.78%,	dividend	yield	of	5.40%,	a	five	year	historical	volatility factor	of	0.28	and	an	expected	option	life	of	five	years.

In	January	2015,	we	granted	certain	employees	PSUs	with	an	aggregate	target	award	of	approximately	0.2	million	shares	of	our	common	stock.	The	PSUs	vest three	years	from	the	grant	date	based	on	continuous	service,	with	the	number	of	shares	earned	(0%	to	200%	of	the	target	award)	depending	upon	the	extent	to	which	we achieve	certain	financial	and	market	performance	targets	measured	over	the	period	from	January	1,	2015	through	December	31,	2017.	About	half	of	the	PSUs	were valued	at	$192.28	per	PSU	in	a	manner	similar	to	RSUs	mentioned	above	as	the	financial	targets	are	based	on	our	operating	results.	We	recognize	the	grant-date	fair value	of	these	PSUs,	less	estimated	forfeitures,	as	compensation	expense	ratably	over	the	vesting	period	based	on	the	number	of	awards	expected	to	vest	at	each reporting	date.	The	remaining	PSUs	were	valued	at	$188.96	per	PSU	using	a	Monte	Carlo	model	as	the	performance	target	is	related	to	our	total	shareholder	return relative	to	our	peer	group.	We	recognize	the	grant-date	fair	value	of	these	awards,	less	estimated	forfeitures,	as	compensation	expense	ratably	over	the	vesting	period.

# Note	14	–	Legal	Proceedings,	Commitments	and	Contingencies

We	are	a	party	to	or	have	property	subject	to	litigation	and	other	proceedings	that	arise	in	the	ordinary	course	of	our	business,	including	matters	arising	under provisions	relating	to	the	protection	of	the	environment	and	are	subject	to	contingencies	related	to	certain	businesses	we	previously	owned.	These	types	of	matters	could result	in	fines,	penalties,	compensatory	or	treble	damages	or	non-monetary	sanctions	or	relief.	We	believe	the	probability	is	remote	that	the	outcome	of	each	of	these matters,	including	the	legal	proceedings	described	below,	will	have	a	material	adverse	effect	on	the	Corporation	as	a	whole,	notwithstanding	that	the	unfavorable resolution	of	any	matter	may	have	a	material	effect	on	our	net	earnings	in	any	particular	interim	reporting	period.	Among	the	factors	that	we	consider	in	this	assessment are	the	nature	of	existing	legal	proceedings	and	claims,	the	asserted	or	possible	damages	or	loss	contingency	(if	estimable),	the	progress	of	the	case,	existing	law	and precedent,	the	opinions	or	views	of	legal	counsel	and	other	advisers,	our	experience	in	similar	cases	and	the	experience	of	other	companies,	the	facts	available	to	us	at the	time	of	assessment	and	how	we	intend	to	respond	to	the	proceeding	or	claim.	Our	assessment	of	these	factors	may	change	over	time	as	individual	proceedings	or claims	progress.

Although	we	cannot	predict	the	outcome	of	legal	or	other	proceedings	with	certainty,	where	there	is	at	least	a	reasonable	possibility	that	a	loss	may	have	been incurred,	GAAP	requires	us	to	disclose	an	estimate	of	the	reasonably	possible	loss	or	range	of	loss	or	make	a	statement	that	such	an	estimate	cannot	be	made.	We	follow a	thorough	process	in	which	we	seek	to	estimate	the	reasonably	possible	loss	or	range	of	loss,	and	only	if	we	are	unable	to	make	such	an	estimate	do	we	conclude	and disclose	that	an	estimate	cannot	be	made.	Accordingly,	unless	otherwise	indicated	below	in	our	discussion	of	legal	proceedings,	a	reasonably	possible	loss	or	range	of loss	associated	with	any	individual	legal	proceeding	cannot	be	estimated.

# Legal	Proceedings

As	a	result	of	our	acquisition	of	Sikorsky,	we	have	assumed	the	defense	of	and	any	potential	liability	for	the	following	civil	False	Claims	Act	lawsuit.	In	October 2014,	the	U.S.	Government	filed	a	complaint	in	the	U.S.	District	Court	for	the	Eastern	District	of	Wisconsin	alleging	that	Sikorsky	and	two	of	its	wholly-owned subsidiaries,	Derco	Aerospace	(Derco)	and	Sikorsky	Support	Services,	Inc.	(SSSI),	violated	the	civil	False	Claims	Act	in	connection	with	a	contract	that	the	U.S.	Navy awarded	to	SSSI	in	June	2006	to	support	the	Navy's	T-34	and	T-44	fixed-wing	turboprop	training	aircraft.	SSSI	subcontracted	with	Derco	primarily	to	procure	and manage	the	spare	parts	for	the	training	aircraft.	The	Government	alleges	that	SSSI	overbilled	the	Navy	on	the	contract	because	Derco	added	profit	and	overhead	costs	to the	price	of	the	spare	parts	that	Derco	procured	and	then	sold	to	SSSI.	The	Government	also	claims	that	SSSI	submitted	false	Certificates	of	Final	Indirect	Costs	in	the years	2006	through	2012.

The	Government's	complaint	asserts	numerous	claims	for	violations	of	the	False	Claims	Act,	breach	of	contract	and	unjust	enrichment.	In	a	late	April	2015	court filing,	the	Government	disclosed	that	it	seeks	damages	of	approximately	$45	million,	subject	to	trebling,	plus	statutory	penalties	of	approximately	$13	million,	all totaling	approximately	$147	million.	We	believe	that	we	have	substantial	legal	and	factual	defenses	to	the	government's	claims.	Although	we	continue	to	evaluate liability	and	exposure,	we	do	not	currently	believe	that	it	is	probable	that	we	will	incur	a	material	loss.	If,	contrary	to	our	expectations,	the	Government	prevails	in	this matter	and	proves	damages	at	the	high	end	of	the	range	sought	and	is	successful	in	having	these	trebled,	the	outcome	could	have	an	adverse	effect	on	our	results	of operations	in	the	period	in	which	a	liability	is	recognized	and	on	our	cash	flows	for	the	period	in	which	any	damages	are	paid.

Additionally,	by	letter	dated	July	13,	2015,	the	United	States	Department	of	Justice	notified	Sikorsky	that	it	had	opened	a	criminal	investigation	into	this	matter, and	requested	that	Sikorsky	and	its	two	subsidiaries	voluntarily	produce	documents.	Sikorsky	and	its	subsidiaries	cooperated	fully	in	the	investigation.	On	February	4, 2016,	we	were	informed	that	the	Department	of	Justice	is	closing	the	criminal	investigation	with	no	action	to	the	corporate	entities	or	individuals.

On	April	24,	2009,	we	filed	a	declaratory	judgment	action	against	the	New	York	Metropolitan	Transportation	Authority	and	its	Capital	Construction	Company (collectively,	the	MTA)	asking	the	U.S.	District	Court	for	the	Southern	District	of	New	York	to	find	that	the	MTA	is	in	material	breach	of	our	agreement	based	on	the MTA's	failure	to	provide	access	to	sites	where	work	must	be	performed	and	the	customer-furnished	equipment	necessary	to	complete	the	contract.	The	MTA	filed	an answer	and	counterclaim	alleging	that	we	breached	the	contract	and	subsequently	terminated	the	contract	for	alleged	default.	The	primary	damages	sought	by	the	MTA are	the	cost	to	complete	the	contract	and	potential	re-procurement	costs.	While	we	are	unable	to	estimate	the	cost	of	another	contractor	to	complete	the	contract	and	the costs	of	re-procurement,	we	note	that	our	contract	with	the	MTA	had	a	total	value	of	$323	million,	of	which	$241	million	was	paid	to	us,	and	that	the	MTA	is	seeking damages	of	approximately	$190	million.	We	dispute	the	MTA's	allegations	and	are	defending	against	them.	Additionally,	following	an	investigation,	our	sureties	on	a performance	bond	related	to	this	matter,	who	were	represented	by	independent	counsel,	concluded	that	the	MTA's	termination	of	the	contract	was	improper.	Finally,	our declaratory	judgment	action	was	later	amended	to	include	claims	for	monetary	damages	against	the	MTA	of	approximately	$95	million.	This	matter	was	taken	under submission	by	the	District	Court	in	December	2014,	after	a	five-week	bench	trial	and	the	filing	of	post-trial	pleadings	by	the	parties.	We	expect	a	decision	in	2016.

We	have	reached	an	agreement	to	settle	with	the	U.S.	Department	of	Justice	(DOJ)	and	the	qui	tam	relators	two	lawsuits	in	which	the	DOJ	filed	complaints	in partial	intervention	on	August	28,	2003.	The	lawsuits,	United	States	ex	rel.	Natural	Resources	Defense	Council,	et	al.,	v.	Lockheed	Martin	Corporation,	et	al.,	and United	States	ex	rel.	John	D.	Tillson	v.	Lockheed	Martin	Energy	Systems,	Inc.,	et	al.,	were	filed	by	the	relators	in	1999	under	the	civil	qui	tam	provisions	of	the	False Claims	Act	in	the	U.S.	District	Court	for	the	Western	District	of	Kentucky	and	alleged	that	we	committed	violations	of	the	Resource	Conservation	and	Recovery	Act (RCRA)	at	the	Paducah	Gaseous	Diffusion	Plant	by	not	properly	handling,	storing	and	transporting	hazardous	waste	and	that	we	violated	the	False	Claims	Act	by misleading	Department	of	Energy	officials	and	state	regulators	about	the	nature	and	extent	of	environmental	noncompliance	at	the	plant.	The	parties	are	finalizing	the terms	of	the	settlement	agreement,	which	is	considered	a	tentative	agreement	until	it	is	formally	approved	by	the	United	States	Government.	The	amount	of	the settlement	is	not	material.	We	believe	that	we	have	substantial	defenses	to	all	of	the	allegations	and	have	agreed	to	settle	the	case	to	avoid	the	costs	of	further	litigation of	this	matter	which	has	been	ongoing	in	excess	of	sixteen	years.	We	will	admit	no	liability	or	wrongdoing	in	resolving	the	matter.	See	Item	3	-	Legal	Proceedings	of	our Annual	Report	on	Form	10-K	for	the	year	ended	December	31,	2015	for	additional	information.

We	are	involved	in	environmental	proceedings	and	potential	proceedings	relating	to	soil	and	groundwater	contamination,	disposal	of	hazardous	waste	and	other environmental	matters	at	several	of	our	current	or	former	facilities	or	at	third-party	sites	where	we	have	been	designated	as	a	potentially	responsible	party	(PRP).	A substantial	portion	of	environmental	costs	will	be	included	in	our	net	sales	and	cost	of	sales	in	future	periods	pursuant	to	U.S.	Government	regulations.	At	the	time	a liability	is	recorded	for	future	environmental	costs,	we	record	a	receivable	for	estimated	future	recovery	considered	probable	through	the	pricing	of	products	and	services to	 agencies	 of	 the	 U.S.	 Government,	 regardless	 of	 the	 contract	 form	 (e.g.,	 cost-reimbursable,	 fixed-price).	 We	 continuously	 evaluate	 the	 recoverability	 of	 our environmental	receivables	by	assessing,	among	other	factors,	U.S.	Government	regulations,	our	U.S.	Government	business	base	and	contract	mix	and	our	history	of receiving	reimbursement	of	such	costs.	We	include	the	portion	of	those	environmental	costs	expected	to	be	allocated	to	our	non-U.S.	Government	contracts,	or	that	is determined	to	not	be	recoverable	under	U.S.	Government	contracts,	in	our	cost	of	sales	at	the	time	the	liability	is	established.

At	December	31,	2015	and	2014,	the	aggregate	amount	of	liabilities	recorded	relative	to	environmental	matters	was	$1.0	billion	and	$965	million,	most	of	which are	recorded	in	other	noncurrent	liabilities	on	our	Balance	Sheets.	We	have	recorded	receivables	totaling	$858	million	and	$836	million	at	December	31,	2015	and	2014, most	of	which	are	recorded	in	other	noncurrent	assets	on	our	Balance	Sheets,	for	the	estimated	future	recovery	of	these	costs,	as	we	consider	the	recovery	probable	based on	the	factors	previously	mentioned.	We	project	costs	and	recovery	of	costs	over	approximately	20	years.	Our	acquisition	of	Sikorsky	included	certain	environmental remediation	liabilities	that	are	among	those	recorded	on	our	Balance	Sheet,	along	with	the	related	receivables	for	probable	future	recovery.	These	amounts	did	not materially	impact	our	consolidated	financial	statements.

Environmental	cleanup	activities	usually	span	several	years,	which	makes	estimating	liabilities	a	matter	of	judgment	because	of	uncertainties	with	respect	to assessing	the	extent	of	the	contamination	as	well	as	such	factors	as	changing	remediation	technologies	and	continually	evolving	regulatory	environmental	standards. There	are	a	number	of	former	operating	facilities	that	we	are	monitoring	or	investigating	for	potential	future	remediation.	We	perform	quarterly	reviews	of	the	status	of our	environmental	remediation	sites	and	the	related	liabilities	and	receivables.	Additionally,	in	our	quarterly

reviews	we	consider	these	and	other	factors	in	estimating	the	timing	and	amount	of	any	future	costs	that	may	be	required	for	remediation	activities	and	record	a	liability when	it	is	probable	that	a	loss	has	occurred	and	the	loss	can	be	reasonably	estimated.	The	amount	of	liability	recorded	is	based	on	our	estimate	of	the	costs	to	be	incurred for	remediation	at	a	particular	site.	We	do	not	discount	the	recorded	liabilities,	as	the	amount	and	timing	of	future	cash	payments	are	not	fixed	or	cannot	be	reliably determined.	We	reasonably	cannot	determine	the	extent	of	our	financial	exposure	in	all	cases	as,	although	a	loss	may	be	probable	or	reasonably	possible,	in	some	cases it	is	not	possible	at	this	time	to	estimate	the	loss	or	reasonably	possible	loss	or	range	of	loss.

We	also	are	pursuing	claims	for	recovery	of	costs	incurred	or	contribution	to	site	cleanup	costs	against	other	PRPs,	including	the	U.S.	Government,	and	are conducting	remediation	activities	under	various	consent	decrees	and	orders	relating	to	soil,	groundwater,	sediment	or	surface	water	contamination	at	certain	sites	of former	or	current	operations.	Under	an	agreement	related	to	our	Burbank	and	Glendale,	California,	sites,	the	U.S.	Government	reimburses	us	an	amount	equal	to approximately	50%	of	expenditures	for	certain	remediation	activities	in	its	capacity	as	a	PRP	under	the	Comprehensive	Environmental	Response,	Compensation	and Liability	Act	(CERCLA).

On	July	1,	2014,	a	regulation	became	effective	in	California	setting	the	maximum	level	of	the	contaminant	hexavalent	chromium	in	drinking	water	at	10	parts	per billion	(ppb).	In	May	2014,	the	California	Manufacturers	and	Technology	Association	filed	a	suit	alleging	the	10	ppb	threshold	is	lower	than	is	required	to	protect	public health	and	thus	imposes	unjustified	costs	on	the	regulated	community.	We	cannot	predict	the	outcome	of	this	suit	or	whether	other	challenges	may	be	advanced	by	the regulated	community	or	environmental	groups	which	had	sought	a	significantly	higher	and	lower	standard,	respectively.	If	the	new	standard	remains	at	10	ppb,	it	will	not have	a	material	impact	on	our	existing	remediation	costs	in	California.

In	addition,	California	is	reevaluating	its	existing	drinking	water	standard	with	respect	to	a	second	contaminant,	perchlorate,	and	the	U.S.	Environmental	Protection Agency	(U.S.	EPA)	is	also	considering	whether	to	regulate	perchlorate	and	hexavalent	chromium	in	drinking	water.	In	February	2016,	the	Natural	Resources	Defense Council	filed	suit	in	federal	court	in	New	York	against	the	U.S.	EPA	to	compel	the	U.S.	EPA	to	set	an	enforceable	drinking	water	standard	for	perchlorate.	If substantially	lower	standards	are	adopted,	in	either	California	or	at	the	federal	level,	for	perchlorate,	or	if	the	U.S.	EPA	were	to	adopt	a	standard	for	hexavalent chromium	lower	than	10	ppb,	we	expect	a	material	increase	in	our	estimates	for	environmental	liabilities	and	the	related	assets	for	the	portion	of	the	increased	costs	that are	probable	of	future	recovery	in	the	pricing	of	our	products	and	services	for	the	U.S.	Government.	The	amount	that	would	be	allocable	to	our	non-U.S.	Government contracts	or	that	is	determined	to	not	be	recoverable	under	U.S.	Government	contracts	would	be	expensed,	which	may	have	a	material	effect	on	our	earnings	in	any particular	interim	reporting	period.

# Operating	Leases

We	rent	certain	equipment	and	facilities	under	operating	leases.	Certain	major	plant	facilities	and	equipment	are	furnished	by	the	U.S.	Government	under	short-term or	cancelable	arrangements.	Our	total	rental	expense	under	operating	leases	was	$256	million,	$258	million	and	$315	million	for	2015,	2014	and	2013.	Future	minimum lease	commitments	at	December	31,	2015	for	long-term	non-cancelable	operating	leases	were	$793	million	($205	million	in	2016,	$161	million	in	2017,	$128	million	in 2018,	$101	million	in	2019,	$64	million	in	2020	and	$134	million	in	later	years).

# Letters	of	Credit,	Surety	Bonds	and	Third-Party	Guarantees

We	have	entered	into	standby	letters	of	credit,	surety	bonds	and	third-party	guarantees	with	financial	institutions	and	other	third	parties	primarily	relating	to advances	received	from	customers	and	the	guarantee	of	future	performance	on	certain	contracts.	Letters	of	credit	and	surety	bonds	generally	are	available	for	draw	down in	the	event	we	do	not	perform.	In	some	cases,	we	may	guarantee	the	contractual	performance	of	third	parties	such	as	venture	partners.	We	had	total	outstanding	letters of	credit,	surety	bonds	and	third-party	guarantees	aggregating	$3.8	billion	at	December	31,	2015	and	$2.4	billion	at	December	31,	2014.

At	December	31,	2015	and	2014,	third-party	guarantees	totaled	$678	million	and	$774	million,	of	which	approximately	79%	and	85%	related	to	guarantees	of contractual	performance	of	ventures	to	which	we	currently	are	or	previously	were	a	party.	This	amount	represents	our	estimate	of	the	maximum	amount	we	would	expect to	incur	upon	the	contractual	non-performance	of	the	venture	partners.	In	addition,	we	generally	have	cross-indemnities	in	place	that	may	enable	us	to	recover	amounts that	may	be	paid	on	behalf	of	a	venture	partner.	We	believe	our	current	and	former	venture	partners	will	be	able	to	perform	their	obligations,	as	they	have	done	through December	31,	2015,	and	that	it	will	not	be	necessary	to	make	payments

under	the	guarantees.	In	determining	our	exposures,	we	evaluate	the	reputation,	technical	capabilities	and	credit	quality	of	our	current	and	former	venture	partners.	There were	no	material	amounts	recorded	in	our	financial	statements	related	to	third-party	guarantees.

# United	Launch	Alliance

Our	50%	ownership	share	of	ULA's	net	assets	exceeded	the	book	value	of	our	investment	by	approximately	$395	million	(of	which	approximately	$40	million remains	at	December	31,	2015	that	will	be	amortized	in	2016).	This	yearly	amortization	and	our	share	of	ULA's	net	earnings	are	reported	as	equity	in	net	earnings (losses)	of	equity	investees	in	other	income,	net	on	our	Statements	of	Earnings.	Our	investment	in	ULA	totaled	$748	million	and	$706	million	at	December	31,	2015	and 2014.

# Note	15	–	Restructuring	Charges

During	2015,	we	recorded	severance	charges	totaling	$102	million,	of	which	$67	million	related	to	our	MST	business	segment	and	$35	million	related	to	our IS&GS	business	segment	(prior	to	realignment).	These	charges	reduced	our	2015	net	earnings	by	$66	million	($.21	per	share).	These	severance	actions	resulted	from	a review	of	future	workload	projections	and	to	reduce	our	overhead	costs	in	order	to	improve	the	affordability	of	our	products	and	services.	The	charges	consisted	of severance	costs	associated	with	the	planned	elimination	of	certain	positions	through	either	voluntary	or	involuntary	actions.	Upon	separation,	terminated	employees	will receive	 lump-sum	severance	payments	primarily	based	on	years	of	service,	 the	majority	of	which	are	expected	 to	be	paid	over	 the	next	several	quarters.	As	of December	31,	2015,	we	have	paid	approximately	$18	million	in	severance	payments	associated	with	these	actions.

We	also	expect	to	incur	accelerated	costs	(e.g.,	accelerated	depreciation	expense	related	to	long-lived	assets	at	sites	closed)	and	incremental	costs	(e.g.,	relocation of	equipment	and	other	employee	related	costs)	of	approximately	$10	million,

$50	million	and	$180	million	at	our	IS&GS,	MST	and	Space	Systems	business	segments	through	the	completion	of	the	plan	in	2016.	As	of	December	31,	2015,	we have	incurred	total	accelerated	and	incremental	costs	of	approximately	$225	million,	of	which	approximately	$115	million,	$90	million	and	$20	million	was	recorded	in 2015,	2014	and	2013,	respectively.	The	accelerated	and	incremental	costs	are	recorded	as	incurred	in	cost	of	sales	on	our	Statements	of	Earnings	and	included	in	the respective	business	segment's	results	of	operations.

We	expect	to	recover	a	substantial	amount	of	the	restructuring	charges	through	the	pricing	of	our	products	and	services	to	the	U.S.	Government	and	other	customers in	future	periods,	with	the	impact	included	in	the	respective	business	segment's	results	of	operations.	Of	the	total	severance,	accelerated	and	incremental	costs	mentioned above,	we	recovered	approximately	$65	million	in	2015	and	$50	million	in	2014	and	expect	to	recover	approximately	$60	million	in	2016.

# Note	16	–	Fair	Value	Measurements

Assets	and	liabilities	measured	and	recorded	at	fair	value	on	a	recurring	basis	consisted	of	the	following	(in	millions):

|  | Total | December	31,	2015<br>Level	1 | Level	2 | Total | December	31,	2014<br>Level	1 | Level	2 |
| :--- | :--- | :--- | :--- | :--- | :--- | :--- |
| Assets |  |  |  |  |  |  |
| Equity\tsecurities | $89 | $\t\t89 | $\t\t— | $92 | $\t\t92 | $\t\t— |
| Mutual\tfunds | 745 | 745 | — | 696 | 696 | — |
| U.S.\tGovernment\tsecurities | 119 | — | 119 | 136 | — | 136 |
| Other\tsecurities | 147 | — | 147 | 153 | — | 153 |
| Derivatives | 15 | — | 15 | 27 | — | 27 |
| Liabilities |  |  |  |  |  |  |
| Derivatives | 35 | — | 35 | 18 | — | 18 |

Substantially	all	assets	measured	at	fair	value,	other	than	derivatives,	represent	investments	classified	as	trading	securities	held	in	a	separate	trust	to	fund	certain	of our	non-qualified	deferred	compensation	plans	and	are	recorded	in	other	noncurrent	assets	on	our	Balance	Sheets.	The	fair	values	of	equity	securities	and	mutual	funds are	determined	by	reference	to	the	quoted	market	price	per	unit	in	active	markets	multiplied	by	the	number	of	units	held	without	consideration	of	transaction	costs.	The fair	values	of	U.S.	Government	and	other	securities	are	determined	using	pricing	models	that	use	observable	inputs	(e.g.,	interest	rates	and	yield	curves	observable	at commonly	quoted	intervals),	bids	provided	by	brokers	or	dealers	or	quoted	prices	of	securities	with	similar	characteristics.	The	fair	values	of	derivative	instruments, which	consist	of	foreign	currency	exchange	forward	and	interest	rate	swap	contracts,	primarily	are	determined	based	on	the	present	value	of	future	cash	flows	using model-derived	valuations	that	use	observable	inputs	such	as	interest	rates,	credit	spreads	and	foreign	currency	exchange	rates.	We	did	not	have	any	transfers	of	assets	or liabilities	between	levels	of	the	fair	value	hierarchy	during	2015.

In	addition	to	the	financial	instruments	listed	in	the	table	above,	we	hold	other	financial	instruments,	including	cash	and	cash	equivalents,	receivables,	accounts payable	and	debt.	The	carrying	amounts	for	cash	and	cash	equivalents,	receivables	and	accounts	payable	approximated	their	fair	values.	The	estimated	fair	value	of	our outstanding	debt	was	$16.5	billion	and	$7.9	billion	at	December	31,	2015	and	2014	and	 the	outstanding	principal	amount	was	$16.2	billion	and	$7.0	billion	at December	31,	2015	and	2014,	excluding	unamortized	discounts	of	$941	million	and	$872	million.	The	estimated	fair	values	of	our	outstanding	debt	were	determined based	on	quoted	prices	for	similar	instruments	in	active	markets	(Level	2).

In	connection	with	the	Sikorsky	acquisition,	we	recorded	the	assets	acquired	and	liabilities	assumed	at	fair	value.	The	amounts	recorded	for	certain	assets	and liabilities	 are	 preliminary	 in	 nature	 and	 are	 subject	 to	 adjustment	 as	 additional	 information	 is	 obtained	 about	 the	 facts	 and	 circumstances	 that	 existed	 as	 of	 the November	6,	2015	acquisition	date.	See	Note	3	for	further	information	about	the	fair	values	assigned	and	amounts	subject	to	adjustment.

In	the	fourth	quarter	of	2014,	we	recorded	non-cash	goodwill	impairment	charge	of	$119	million	in	connection	with	our	annual	goodwill	impairment	test.	The	fair value	determination	of	goodwill	was	determined	using	a	combination	of	a	DCF	analysis	and	market-based	valuation	methodologies	and	was	classified	as	a	Level	3	fair value	measurement	due	to	the	significance	of	the	unobservable	inputs	used.	See	Note	1	for	further	information	on	this	non-cash	goodwill	impairment	charge	and	our valuation	methodologies.

# Note	17	–	Summary	of	Quarterly	Information	(Unaudited)

(a) The	fourth	quarter	of	2015	incorporates	the	results	of	Sikorsky	from	the	November	6,	2015	acquisition	date	through	December	31,	2015,	including	approximately	$400	million	in net	sales	and	about	$45	million	in	operating	loss,	inclusive	of	intangible	amortization	and	adjustments	required	to	account	for	the	acquisition.

(b) The	fourth	quarter	of	2015	includes	a	charge	for	workforce	reductions	of	approximately	$67	million	($44	million	after	tax)	and	a	tax	benefit	of	about	$71	million	due	to	the retroactive	reinstatement	of	the	R&D	tax	credit	in	2015.

(c) The	sum	of	the	quarterly	earnings	per	share	amounts	do	not	equal	the	earnings	per	share	amounts	included	on	our	Statements	of	Earnings,	primarily	due	to	the	timing	of	our share	repurchases	during	each	respective	year.

(d) The	fourth	quarter	of	2014	includes	a	charge	of	approximately	$119	million	($107	million	after	tax)	related	to	a	non-cash	goodwill	impairment	charge	and	a	tax	benefit	of	about $45	million	due	to	the	retroactive	reinstatement	of	the	R&D	tax	credit	in	2014.

# ITEM	9. Changes	in	and	Disagreements	with	Accountants	on	Accounting	and	Financial	Disclosure.

# ITEM	9A. Controls	and	Procedures.

# Evaluation	of	Disclosure	Controls	and	Procedures

We	performed	an	evaluation	of	the	effectiveness	of	our	disclosure	controls	and	procedures	as	of	December	31,	2015.	The	evaluation	was	performed	with	the participation	of	senior	management	of	each	business	segment	and	key	Corporate	functions,	under	the	supervision	of	the	Chief	Executive	Officer	(CEO)	and	Chief Financial	Officer	(CFO).	Based	on	 this	evaluation,	 the	CEO	and	CFO	concluded	 that	our	disclosure	controls	and	procedures	were	operating	and	effective	as	of December	31,	2015.

# Management's	Report	on	Internal	Control	Over	Financial	Reporting

Our	management	is	responsible	for	establishing	and	maintaining	adequate	internal	control	over	financial	reporting.	Our	internal	control	system	was	designed	to provide	reasonable	assurance	to	our	management	and	board	of	directors	regarding	the	reliability	of	financial	reporting	and	the	preparation	of	financial	statements	for external	purposes.

Our	management	conducted	an	assessment	of	the	effectiveness	of	our	internal	control	over	financial	reporting	as	of	December	31,	2015.	This	assessment	was	based on	the	criteria	set	forth	by	the	Committee	of	Sponsoring	Organizations	of	the	Treadway	Commission	in	Internal	Control	–	Integrated	Framework	(2013	framework). Based	on	this	assessment,	management	has	concluded	that,	as	of	December	31,	2015,	our	internal	control	over	financial	reporting	was	effective.

Our	assessment	of	the	effectiveness	of	our	internal	control	over	financial	reporting	as	of	December	31,	2015	did	not	include	an	assessment	of	the	effectiveness	of internal	control	over	financial	reporting	of	Sikorsky	Aircraft	Corporation	(Sikorsky),	which	was	acquired	on	November	6,	2015.	The	operating	results	of	Sikorsky	are included	in	our	consolidated	financial	statements	from	the	period	subsequent	to	the	acquisition	date	and,	excluding	goodwill	and	intangible	assets,	include	$5.0	billion	of assets	as	of	December	31,	2015	and	$400	million	and	$45	million	in	net	sales	and	operating	loss,	respectively,	for	the	year	then	ended.	We	will	perform	an	assessment	of the	effectiveness	of	Sikorsky's	internal	control	over	financial	reporting	within	one	year	of	the	date	of	acquisition.

Our	independent	registered	public	accounting	firm	has	issued	a	report	on	the	effectiveness	of	our	internal	control	over	financial	reporting,	which	is	below.

# Changes	in	Internal	Control	Over	Financial	Reporting

Except	as	described	below,	here	were	no	changes	in	our	internal	control	over	financial	reporting	during	the	most	recently	completed	fiscal	quarter	that	materially affected,	or	are	reasonably	likely	to	materially	affect,	our	internal	control	over	financial	reporting.

We	are	in	the	process	of	integrating	Sikorsky's	operations	with	our	operations,	including	integration	of	financial	reporting	processes	and	procedures	and	internal controls	over	financial	reporting.	We	believe	we	will	be	able	to	maintain	sufficient	controls	over	our	financial	reporting	throughout	this	integration	process.	Because	of the	size	and	complexity	and	the	timing	of	the	Sikorsky	acquisition,	the	internal	controls	over	financial	reporting	of	Sikorsky	have	been	excluded	from	our	assessment	of the	effectiveness	of	our	internal	control	over	financial	reporting	as	of	December	31,	2015	(as	described	above).

# Regarding	Internal	Control	Over	Financial	Reporting

We	have	audited	Lockheed	Martin	Corporation's	 internal	control	over	financial	reporting	as	of	December	31,	2015,	based	on	criteria	established in	Internal Control–Integrated	Framework	issued	by	the	Committee	of	Sponsoring	Organizations	of	the	Treadway	Commission	(2013	framework)	(the	COSO	criteria).	Lockheed Martin	Corporation's	management	is	responsible	for	maintaining	effective	internal	control	over	financial	reporting,	and	for	its	assessment	of	the	effectiveness	of	internal control	over	financial	reporting	included	in	the	accompanying	Management's	Report	on	Internal	Control	Over	Financial	Reporting.	Our	responsibility	is	to	express	an opinion	on	the	Corporation's	internal	control	over	financial	reporting	based	on	our	audit.

We	conducted	our	audit	in	accordance	with	the	standards	of	the	Public	Company	Accounting	Oversight	Board	(United	States).	Those	standards	require	that	we	plan and	perform	the	audit	to	obtain	reasonable	assurance	about	whether	effective	internal	control	over	financial	reporting	was	maintained	in	all	material	respects.	Our	audit included	obtaining	an	understanding	of	internal	control	over	financial	reporting,	assessing	the	risk	that	a	material	weakness	exists,	testing	and	evaluating	the	design	and operating	effectiveness	of	internal	control	based	on	the	assessed	risk,	and	performing	such	other	procedures	as	we	considered	necessary	in	the	circumstances.	We	believe that	our	audit	provides	a	reasonable	basis	for	our	opinion.

A	company's	internal	control	over	financial	reporting	is	a	process	designed	to	provide	reasonable	assurance	regarding	the	reliability	of	financial	reporting	and	the preparation	of	financial	statements	for	external	purposes	in	accordance	with	generally	accepted	accounting	principles.	A	company's	internal	control	over	financial reporting	includes	those	policies	and	procedures	that	(1)	pertain	to	the	maintenance	of	records	that,	in	reasonable	detail,	accurately	and	fairly	reflect	the	transactions	and dispositions	of	the	assets	of	the	company;	(2)	provide	reasonable	assurance	that	transactions	are	recorded	as	necessary	to	permit	preparation	of	financial	statements	in accordance	with	generally	accepted	accounting	principles,	and	that	receipts	and	expenditures	of	the	company	are	being	made	only	in	accordance	with	authorizations	of management	 and	 directors	 of	 the	 company;	 and	 (3)	 provide	 reasonable	 assurance	 regarding	 prevention	 or	 timely	 detection	 of	 unauthorized	 acquisition,	 use,	 or disposition	of	the	company's	assets	that	could	have	a	material	effect	on	the	financial	statements.

Because	of	 its	 inherent	 limitations,	 internal	control	over	financial	reporting	may	not	prevent	or	detect	misstatements.	Also,	projections	of	any	evaluation	of effectiveness	to	future	periods	are	subject	to	the	risk	that	controls	may	become	inadequate	because	of	changes	in	conditions,	or	that	the	degree	of	compliance	with	the policies	or	procedures	may	deteriorate.

As	 indicated	 in	 the	accompanying	Management's	Report	on	Internal	Control	Over	Financial	Reporting,	management's	assessment	of	and	conclusion	on	 the effectiveness	 of	 internal	 control	 over	 financial	 reporting	 did	 not	 include	 the	 internal	 controls	 of	 Sikorsky	Aircraft	 Corporation,	 which	 is	 included	 in	 the	 2015 consolidated	financial	statements	of	Lockheed	Martin	Corporation	and	constituted	$5.0	billion	of	assets	(excluding	goodwill	and	intangible	assets)	as	of	December	31, 2015	and	$400	million	and	$45	million	of	net	sales	and	operating	loss,	respectively,	for	the	year	then	ended.	Our	audit	of	internal	control	over	financial	reporting	of Lockheed	Martin	Corporation	also	did	not	include	an	evaluation	of	the	internal	control	over	financial	reporting	of	Sikorsky	Aircraft	Corporation.

In	our	opinion,	Lockheed	Martin	Corporation	maintained,	in	all	material	respects,	effective	internal	control	over	financial	reporting	as	of	December	31,	2015,	based on	the	COSO	criteria.

We	also	have	audited,	in	accordance	with	the	standards	of	the	Public	Company	Accounting	Oversight	Board	(United	States),	the	consolidated	balance	sheets	of Lockheed	Martin	Corporation	as	of	December	31,	2015	and	2014,	and	the	related	consolidated	statements	of	earnings,	comprehensive	income,	stockholders'	equity,	and cash	flows	for	each	of	the	three	years	in	the	period	ended	December	31,	2015	of	Lockheed	Martin	Corporation	and	our	report	dated	February	24,	2016	expressed	an unqualified	opinion	thereon.
