Boeing Military Aircraft Results of Operations
## Table 1 ##
Revenues BMA revenues in 2015 decreased by $18 million compared with 2014 primarily due to lower revenues of $1,083 million from fewer deliveries and mix on the F/A-18, Apache and V-22 programs, partially offset by higher revenues related to a cumulative catch-up adjustment recorded in the third quarter of 2015 on the F-15 program due to contract negotiations and higher milestone revenue on the USAF KC-46A Tanker program.
BMA revenues in 2014 decreased by $1,775 million, or 12%, compared with 2013 primarily due to a reduction of revenue of $1,730 million related to F-15 and USAF KC-46A Tanker milestones, fewer C-17 aircraft deliveries and delivery mix on the P-8 program.
Earnings From Operations BMA earnings from operations in 2015 increased by $17 million compared with 2014 primarily due to lower C-17 charges, higher Chinook deliveries and higher earnings on the F-15 program, primarily due to a cumulative catch-up adjustment recorded in the third quarter of 2015.
These increases were partially offset by higher charges of $135 million on the USAF KC-46A Tanker contract and lower earnings on proprietary programs.
BMA recorded charges of $322 million in the second quarter of 2015 and $187 million in the second quarter of 2014 related to the USAF KC-46A Tanker contract.
In addition, BMA recorded a charge of $48 million in the first quarter of 2014 to write-off inventory and accrue termination liabilities as a result of our decision to produce three fewer C-17 aircraft in 2015 than previously planned.
Net favorable cumulative contract catch-up adjustments were $96 million lower in 2015 than in 2014 primarily driven by the USAF KC-46A Tanker charges and lower favorable F/A-18 adjustments, partially offset by higher favorable F-15 program adjustments.
BMA earnings from operations in 2014 decreased by $200 million, or 13%, compared with 2013 primarily due to 2014 charges of $235 million and lower earnings of $73 million related to fewer deliveries on the C-17 program.
The charges recorded in 2014 included $187 million related to the USAF KC-46A Tanker contract and $48 million to write off inventory and accrue termination liabilities as a result of our 2014 decision to produce three fewer C-17 aircraft in 2015 than previously planned.
See Note 11 to our Consolidated Financial Statements.
These decreases were partially offset by higher earnings of $65 million related to improved performance on the F/A-18 program.
In addition, in 2013, we recorded a charge of $64 million to write off inventory and accrue termination liabilities as a result of the Republic of Korea's announcement to restart its F-X fighter aircraft competition.
Net favorable cumulative contract catch-up adjustments were $39 million lower in 2014 than in 2013 primarily driven by the reach-forward loss on the USAF KC-46A Tanker contract, partially offset by higher favorable adjustments to the F/A-18 and F-15 programs.
Purchase Obligations Recorded on the Consolidated Statements of Financial Position Purchase obligations recorded on the Consolidated Statements of Financial Position primarily include accounts payable and certain other current and long-term liabilities including accrued compensation.
Industrial Participation Agreements We have entered into various industrial participation agreements with certain customers outside of the U. S.  to facilitate economic flow back and/or technology transfer to their businesses or government agencies as the result of their procurement of goods and/or services from us.
These commitments may be satisfied by our placement of direct work or vendor orders for supplies, opportunities to bid on supply contracts, transfer of technology or other forms of assistance.
However, in certain cases, our commitments may be satisfied through other parties (such as our vendors) who purchase supplies from our non-U.
S.  customers.
We do not commit to industrial participation agreements unless a contract for sale of our products or services is signed.
In certain cases, penalties could be imposed if we do not meet our industrial participation commitments.
During 2015, we incurred no such penalties.
As of December 31, 2015, we have outstanding industrial participation agreements totaling $18.4 billion that extend through 2030.
Purchase order commitments associated with industrial participation agreements are included in purchase obligations in the table above.
To be eligible for such a purchase order commitment from us, a foreign supplier must have sufficient capability to meet our requirements and must be competitive in cost, quality and schedule.
Commercial Commitments The following table summarizes our commercial commitments outstanding as of December 31, 2015.
## Table 2 ##
Commercial aircraft financing commitments include commitments to provide financing related to aircraft on order, under option for deliveries or proposed as part of sales campaigns based on estimated earliest potential funding dates.
Based on historical experience, we anticipate that we will not be required to fund a significant portion of our financing commitments.
However, there can be no assurances that we will not be required to fund greater amounts than historically required.
See Note 11 to our Consolidated Financial Statements.
Contingent Obligations We have significant contingent obligations that arise in the ordinary course of business, which include the following: Legal Various legal proceedings, claims and investigations are pending against us.
Legal contingencies are discussed in Note 20 to our Consolidated Financial Statements.
Environmental Remediation We are involved with various environmental remediation activities and have recorded a liability of $566 million at December 31, 2015.
For additional information, see Note 11 to our Consolidated Financial Statements.
Income Taxes We have $1,617 million of unrecognized tax benefits at December 31, 2015 for uncertain tax positions.
For further discussion of income taxes, see Note 4 to our Consolidated Financial Statements.

Free Cash Flow – Cash generated by operating activities totaled $6.2 billion, reduced by $3.6 billion for cash used in investing activities and a 37% increase in dividends paid, yielding free cash flow of $1.4 billion.
Free cash flow is defined as cash provided by operating activities (adjusted for the reclassification of our receivables securitization facility), less cash used in investing activities and dividends paid.
Free cash flow is not considered a financial measure under accounting principles generally accepted in the U. S.  (GAAP) by SEC Regulation G and Item 10 of SEC Regulation S-K and may not be defined and calculated by other companies in the same manner.
We believe free cash flow is important to management and investors in evaluating our financial performance and measures our ability to generate cash without additional external financings.
Free cash flow should be considered in addition to, rather than as a substitute for, cash provided by operating activities.
The following table reconciles cash provided by operating activities (GAAP measure) to free cash flow (non-GAAP measure):
## Table 3 ##
[a] Effective January 1, 2010, a new accounting standard required us to account for receivables transferred under our receivables securitization facility as secured borrowings in our Consolidated Statements of Financial Position and as financing activities in our Consolidated Statements of Cash Flows.
The receivables securitization facility is included in our free cash flow calculation to adjust cash provided by operating activities as though our receivables securitization facility had been accounted for under the new accounting standard for all periods presented.2013 Outlook ?
Safety – Operating a safe railroad benefits our employees, our customers, our shareholders, and the communities we serve.
We will continue using a multi-faceted approach to safety, utilizing technology, risk assessment, quality control, training and employee engagement, and targeted capital investments.
We will continue using and expanding the deployment of Total Safety Culture throughout our operations, which allows us to identify and implement best practices for employee and operational safety.
Derailment prevention and the reduction of grade crossing incidents are critical aspects of our safety programs.
We will continue our efforts to increase rail defect detection; improve or close crossings; and educate the public and law enforcement agencies about crossing safety through a combination of our own programs (including risk assessment strategies), various industry programs and local community activities across our network.  ?
Network Operations – We will continue focusing on our six critical initiatives to improve safety, service and productivity during 2013.
We are seeing solid contributions from reducing variability, continuous improvements, and standard work.
Resource agility allows us to respond quickly to changing market conditions and network disruptions from weather or other events.
The Railroad continues to benefit from capital investments that allow us to build capacity for growth and harden our infrastructure to reduce failure.  ?
Fuel Prices – Uncertainty about the economy makes projections of fuel prices difficult.
We again could see volatile fuel prices during the year, as they are sensitive to global and U. S.  domestic demand, refining capacity, geopolitical events, weather conditions and other factors.
To reduce the impact of fuel price on earnings, we will continue seeking cost recovery from our customers through our fuel surcharge programs and expanding our fuel conservation efforts.  ?
Capital Plan – In 2013, we plan to make total capital investments of approximately $3.6 billion, including expenditures for Positive Train Control (PTC), which may be revised if business conditions warrant or if new laws or regulations affect our ability to generate sufficient returns on these investments.
(See further discussion in this Item 7 under Liquidity and Capital Resources – Capital Plan. )
