Liquidity and Capital Resources Cash Flow Summary
## Table 0 ##
Operating Activities Net cash provided by operating activities was $9.4 billion during 2015, compared with $8.9 billion during 2014 and $8.2 billion in 2013.
The increase of $0.5 billion in 2015 was primarily due to lower inventory growth, partially offset by lower receipts of advances and progress billings.
The increase of $0.7 billion in 2014 was primarily due to higher customer advances which more than offset higher gross inventory.
Our investment in gross inventories decreased by $0.3 billion in 2015 primarily in our BDS business, largely driven by ending production of C-17 aircraft, which more than offset continued investment in commercial airplane program inventory.
Our investment in gross inventories increased $7.6 billion in 2014 and $5.7 billion in 2013, largely driven by continued investment in commercial airplane program inventory, primarily 787 inventory.
Advances and progress billings increased by $0.4 billion in 2015, $6.9 billion in 2014 and $3.9 billion in 2013, primarily due to payments from Commercial Airplane customers.
Discretionary contributions to our pension plans were insignificant in 2015 compared with $0.8 billion in 2014 and $1.5 billion in 2013.
Investing Activities Cash used by investing activities was $1.8 billion during 2015 compared with $2.5 billion provided during 2014 and $5.2 billion used during 2013, largely due to changes in investments in time deposits.
Net proceeds from investments were $0.6 billion in 2015 compared with $4.8 billion in 2014 and net contributions to investments of $2.9 billion in 2013.
In 2015, capital expenditures totaled $2.5 billion, up from $2.2 billion in 2014 and $2.1 billion in 2013.
We expect capital expenditures in 2016 to be consistent with 2015 due to continued investment to support growth.
Financing Activities Cash used by financing activities was $7.9 billion during 2015, a decrease of $0.7 billion compared with 2014 primarily due to higher new borrowings of $0.8 billion and lower repayments of debt and distribution rights of $0.9 billion in 2015, which more than offset higher share repurchases of $0.8 billion and higher dividend payments of $0.4 billion in 2015.
Cash used by financing activities was $8.6 billion during 2014, an increase of $4.3 billion compared with 2013 primarily due to higher share repurchases of $3.2 billion, higher dividends paid of $0.6 billion and a decrease in proceeds from stock options exercised of $0.8 billion in 2014, partially offset by higher new borrowings of $0.4 billion in 2014.

ITEM 12.
Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters.
The information required by Item 12 is included under the heading “Security Ownership of Management and Certain Beneficial Owners” in the 2017 Proxy Statement, and that information is incorporated by reference in this Form 10-K.  Equity Compensation Plan Information The following table provides information about our equity compensation plans that authorize the issuance of shares of Lockheed Martin common stock to employees and directors.
The information is provided as of December 31, 2016.
## Table 2 ##
(1) Column (a) includes, as of December 31, 2016: 1,747,151 shares that have been granted as Restricted Stock Units (RSUs), 936,308 shares that could be earned pursuant to grants of Performance Stock Units (PSUs) (assuming the maximum number of PSUs are earned and payable at the end of the three-year performance period) and 2,967,046 shares granted as options under the Lockheed Martin Corporation 2011 Incentive Performance Award Plan (2011 IPA Plan) or predecessor plans prior to January 1, 2013 and 23,346 shares granted as options and 128,822 stock units payable in stock or cash under the Lockheed Martin Corporation 2009 Directors Equity Plan (Directors Equity Plan) or predecessor plans for members (or former members) of the Board of Directors.
Column (c) includes, as of December 31, 2016, 5,751,655 shares available for future issuance under the 2011 IPA Plan as options, stock appreciation rights (SARs), restricted stock awards (RSAs), RSUs or PSUs and 464,816 shares available for future issuance under the Directors Equity Plan as stock options and stock units.
Of the 5,751,655 shares available for grant under the 2011 IPA Plan on December 31, 2016, 516,653 and 236,654 shares are issuable pursuant to grants made on January 26, 2017, of RSUs and PSUs (assuming the maximum number of PSUs are earned and payable at the end of the three-year performance period), respectively.
The weighted average price does not take into account shares issued pursuant to RSUs or PSUs.
(2) The shares represent annual incentive bonuses and Long-Term Incentive Performance (LTIP) payments earned and voluntarily deferred by employees.
The deferred amounts are payable under the Deferred Management Incentive Compensation Plan (DMICP).
Deferred amounts are credited as phantom stock units at the closing price of our stock on the date the deferral is effective.
Amounts equal to our dividend are credited as stock units at the time we pay a dividend.
Following termination of employment, a number of shares of stock equal to the number of stock units credited to the employee’s DMICP account are distributed to the employee.
There is no discount or value transfer on the stock distributed.
Distributions may be made from newly issued shares or shares purchased on the open market.
Historically, all distributions have come from shares held in a separate trust and, therefore, do not further dilute our common shares outstanding.
As a result, these shares also were not considered in calculating the total weighted average exercise price in the table.
Because the DMICP shares are outstanding, they should be included in the denominator (and not the numerator) of a dilution calculation.
ITEM 13.
Certain Relationships and Related Transactions and Director Independence.
The information required by this Item 13 is included under the captions “Corporate Governance – Related Person Transaction Policy,” “Corporate Governance – Certain Relationships and Related Person Transactions of Directors, Executive Officers, and 5 Percent Stockholders,” and “Corporate Governance – Director Independence” in the 2017 Proxy Statement, and that information is incorporated by reference in this Form 10-K.
ITEM 14.
Principal Accountant Fees and Services.
The information required by this Item 14 is included under the caption “Proposal 2 – Ratification of Appointment of Independent Auditors” in the 2017 Proxy Statement, and that information is incorporated by reference in this Form 10-K.
Total debt at December 31 consisted of the following (in thousands):
## Table 3 ##
The 2016 Facility and Roper’s $3.9 billion senior notes provide substantially all of Roper’s daily external financing requirements.
The interest rate on the borrowings under the 2016 Facility is calculated based upon various recognized indices plus a margin as defined in the credit agreement.
At December 31, 2017, Roper’s fixed debt consisted of $3.9 billion of senior notes, $3.1 million of other debt in the form of capital leases, several smaller facilities that allow for borrowings or the issuance of letters of credit in foreign locations to support Roper’s non-U.
S.  businesses and $75.9 million of outstanding letters of credit at December 31, 2017.
Future maturities of total debt during each of the next five years ending December 31 and thereafter were as follows
