The Boeing Company and Subsidiaries
Notes to the Condensed Consolidated Financial Statements
(Dollars in millions, except per share data)
(Unaudited)
Note 1 – Basis of Presentation
The condensed consolidated interim financial statements included in this report have been prepared by management of The Boeing Company (herein referred to as “Boeing”, the “Company”, “we”, “us”, or “our”). In the opinion of management, all adjustments (consisting of normal recurring accruals) necessary for a fair presentation are reflected in the interim financial statements. The results of operations for the period ended March 31,September 30, 2016 are not necessarily indicative of the operating results for the full year. The interim financial statements should be read in conjunction with the audited Consolidated Financial Statements, including the notes thereto, included in our 2015 Annual Report on Form 10-K. Certain amounts in prior periods have been reclassified to conform to the current period's presentation.
Standards Issued and Not Yet Implemented
In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016 - 02, Leases (Topic 842). The new standard is effective for reporting periods beginning after December 15, 2018 and early adoption is permitted. The standard will require lessees to report most leases as assets and liabilities on the balance sheet, while lessor accounting will remain substantially unchanged. The standard requires a modified retrospective transition approach for existing leases, whereby the new rules will be applied to the earliest year presented. We do not expect the new lease standard to have a material effect on our financial position, results of operations or cash flows.
In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. The new standard was originally effective for reporting periods beginning after December 15, 2016 and early adoption was not permitted. On August 12, 2015, the FASB approved a one year delay of the effective date to reporting periods beginning after December 15, 2017, while permitting companies to voluntarily adopt the new standard as of the original effective date. The comprehensive new standard will supersede existing revenue recognition guidance and require revenue to be recognized when promised goods or services are transferred to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. Adoption of the new rules could affect the timing of revenue recognition for certain transactions. The guidance permits two implementation approaches, one requiring retrospective application of the new standard with restatement of prior years and one requiring prospective application of the new standard with disclosure of results under old standards. The Company is currently evaluating whenplans to adopt the new standard effective January 1, 2018 and is continuing to evaluate the impacts of adoption and the implementation approach to be used.
Standards Issued and Implemented
In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting. The new standard is effective for reporting periods beginning after December 15, 2016 and early adoption is permitted. The standard requires excess tax benefits or deficiencies for share-based payments to be recorded in the period shares vest or settle as income tax expense or benefit, rather than within Additional paid-in capital. Cash flows related to excess tax benefits will be included in Net cash provided by operating activities and will no longer be separately classified as a financing activity. The standard also allows us to repurchase more of an employee’s shares for tax withholding purposes and provides an accounting policy election to account for forfeitures as they occur. We have elected to continue to estimate forfeitures and are not planning to change tax withholdings.
The Company prospectively adopted the standard during the three months ended June 30, 2016 effective January 1, 2016. For the nine months ended September 30, 2016, this resulted in an increase of $64 to Net earnings and $0.10 to diluted earnings per share and for the three months ended September 30, 2016, an increase of $10 to Net earnings and $0.02 to diluted earnings per share. Adoption also resulted in a $64

increase in Net cash provided by operating activities and a corresponding $64 reduction in Net cash used by financing activities for the nine months ended September 30, 2016.

Use of Estimates
Management makes assumptions and estimates to prepare financial statements in conformity with accounting principles generally accepted in the United States of America. Those assumptions and estimates directly affect the amounts reported in the Condensed Consolidated Financial Statements. Significant estimates for which changes in the near term are considered reasonably possible and that may have a material impact on the financial statements are disclosed in these Notes to the Condensed Consolidated Financial Statements.
Contract accounting is used for development and production activities predominantly by Defense, Space & Security (BDS). Contract accounting involves a judgmental process of estimating total sales and costs for each contract resulting in the development of estimated cost of sales percentages. Changes in estimated revenues, cost of sales and the related effect on operating income are recognized using a cumulative catch-up adjustment which recognizes in the current period the cumulative effect of the changes on current and prior periods based on a contract’s percent complete. For the threenine months ended March 31,September 30, 2016 and 2015, net unfavorable cumulative catch-up adjustments to prior years' earnings, including reach-forward losses, across all contracts decreased Earnings from operations by $84$656 and $384 and diluted earnings per share by $0.09.$0.95 and $0.38. For the three months

ended March 31,September 30, 2016, net unfavorable cumulative catch-up adjustments to prior years' earnings, including reach-forward losses, across all contracts decreased Earnings from operations by $69 and diluted earnings per share by $0.11. For the three months ended September 30, 2015, net favorable cumulative catch-up adjustments, including reach-forward losses, across all contracts increased Earnings from operations by $130$210 and diluted earnings per share by $0.12.$0.21.
Note 2 – Earnings Per Share
Basic and diluted earnings per share are computed using the two-class method, which is an earnings allocation method that determines earnings per share for common shares and participating securities. The undistributed earnings are allocated between common shares and participating securities as if all earnings had been distributed during the period. Participating securities and common shares have equal rights to undistributed earnings.
Basic earnings per share is calculated by taking net earnings, less earnings available to participating securities, divided by the basic weighted average common shares outstanding.
Diluted earnings per share is calculated by taking net earnings, less earnings available to participating securities, divided by the diluted weighted average common shares outstanding.

The elements used in the computation of basic and diluted earnings per share were as follows:

Note 3 – Income Taxes
Our effective income tax rates were 30.0%5.8% and 31.3%(3.4)% for the nine and three months ended March 31,September 30, 2016 and 2015.31.5% for the same periods in the prior year. The 2016 effective tax rate for the three months ended March 31, 2016 wasrates are lower than the comparable prior year period primarily due to $440 of additional tax benefits recorded in the third quarter of 2016 related to the application of a 2012 Federal Court of Claims decision that allowed the tax basis in certain assets to be increased. Also, in the third quarter of 2016 a tax benefit of $177 was recorded as a result of the settlement of the 2011-2012 federal tax audit. Additionally, the 2016 effective tax rates include the favorable impact of the permanent reinstatement of the U.S. research and development tax credit (research credit) at the end of 2015. A
The total amount of unrecognized tax benefit forbenefits decreased from $1,617 as of December 31, 2015 to $1,378 as of September 30, 2016 primarily due to the research credit was recorded duringtax basis adjustment and settlement of the three months ended March 31, 2016, and none in the comparable prior year period.2011-2012 federal tax audit, as discussed above.

Federal income tax audits have been settled for all years prior to 2011.2013. The years 2011-2012 are currently being examined byInternal Revenue Service (IRS) will begin the IRS.2013-2014 federal tax audit in the fourth quarter of 2016. We are also subject to examination in major state and international jurisdictions for the 2001-2015 tax years. We believe appropriate provisions for all outstanding tax issues have been made for all jurisdictions and all open years.
Audit outcomes and the timing of audit settlements are subject to significant uncertainty. It is reasonably possible that within the next 12 months we will resolve the matters presently under consideration for the 2011-2012 tax years with the IRS. Depending on the timing and outcome of that audit settlement, unrecognized tax benefits could decrease by up to $115 based on current estimates.

Long-Term Contracts in Progress
Long-term contracts in progress includes Delta launch program inventory that is being sold at cost to United Launch Alliance (ULA) under an inventory supply agreement that terminates on March 31, 2021. At March 31, 2016, theThe inventory balance was $120 (net of advances of $293)$253 and $120 (net of advances of $310) at September 30, 2016 and December 31, 2015. At March 31, 2016, $176 of this inventory relatedSee indemnifications to unsold launches. SeeULA in Note 9.
Included in inventories are capitalized precontract costs of $650 and $732 primarily related to KC-46A Tanker of $1,163 and $732C-17 at March 31,September 30, 2016andDecember 31, 2015.
Commercial Aircraft Programs
At March 31,September 30, 2016 and December 31, 2015, commercial aircraft programs inventory included the following amounts related to the 787 program: $35,522$33,423 and $34,656 of work in process (including deferred production costs of $28,651$27,523 and $28,510), $2,500$2,345 and $2,551 of supplier advances, and $3,767$3,691 and $3,890 of unamortized tooling and other non-recurring costs. At March 31,September 30, 2016, $23,661$22,521 of 787 deferred production costs, unamortized tooling and other non-recurring costs are expected to be recovered from units included in the program accounting quantity that have firm orders and $8,757$8,693 is expected to be recovered from units included in the program accounting quantity that represent expected future orders.
We produced the fourth and fifth flight test aircraft for the 787 program in 2009 but were unable to sell them at acceptable prices. The aircraft had been used extensively for flight and ground testing and we intended to begin to refurbish the aircraft in early 2017 for commercial sale based on sales activity and market interest. However, during the second quarter of 2016 we determined that firm orders for these aircraft prior to refurbishment were now unlikely, and that the Company would not invest company funds for their refurbishment. The Company also determined the costs to refurbish the aircraft at a future date would be prohibitively expensive. We therefore determined that the aircraft are not commercially saleable, and accordingly, costs of $1,235 associated with these aircraft were reclassified from 787 program inventory to research and development expense. The reclassification also impacted 787 deferred production costs, reducing the balance by $1,011 at June 30, 2016.

At March 31,September 30, 2016 and December 31, 2015, commercial aircraft programs inventory included the following amounts related to the 747 program: $876$0 and $942 of deferred production costs, net of reach-forward losses, and $298 and $377 of unamortized tooling costs. At March 31,September 30, 2016, $402$99 of 747 deferred production and unamortized tooling costs are expected to be recovered from units included in the program accounting quantity that have firm orders and $851$199 is expected to be recovered from units included in the program accounting quantity that represent expected future orders. At March 31,September 30, 2016 and December 31, 2015, work in process inventory included a number of completed 747 aircraft that we expect to recover from future orders.
Commercial aircraft programs inventory included amounts credited in cash or other consideration (early issue sales consideration) to airline customers totaling $3,198$3,257 and $3,166 at March 31,September 30, 2016 and December 31, 2015.
Used aircraft in inventories at Commercial Airplanes totaled $351$224 and $267 at March 31,September 30, 2016 and December 31, 2015.

We determine a receivable is impaired when, based on current information and events, it is probable that we will be unable to collect amounts due according to the original contractual terms. At March 31,September 30, 2016 and December 31, 2015, we individually evaluated for impairment customer financing receivables of $88$61 and $86. At March 31,September 30, 2016 and December 31, 2015, $49$46 and $0 was determined to be impaired. We recorded no allowance for losses on these impaired receivables as the collateral values exceeded the carrying values of the receivables.
The adequacy of the allowance for losses is assessed quarterly. Three primary factors influencing the level of our allowance for losses on customer financing receivables are customer credit ratings, default rates and collateral values. We assign internal credit ratings for all customers and determine the creditworthiness of each customer based upon publicly available information and information obtained directly from our customers. Our rating categories are comparable to those used by the major credit rating agencies.

Our financing receivable balances by internal credit rating category are shown below.below:

At March 31,September 30, 2016, our allowance related to receivables with ratings of B, BB and BBB. We applied default rates that averaged 13%, 10%9% and 2%1%, respectively, to the exposure associated with those receivables.
Customer Financing Exposure
Customer financing is collateralized by security in the related asset. The value of the collateral is closely tied to commercial airline performance and overall market conditions and may be subject to reduced valuation with market decline. Declines in collateral values are also a significant driver of ourcould result in asset impairments, reduced finance lease income, and an increase in the allowance for losses. Our customer financing collateral is concentrated in 747-8 and out-of-production aircraft. Generally, out-of-production aircraft have experienced greater collateral value declines than in-production aircraft. Our customer financing portfolio is primarily collateralized by out-of-production aircraft.
The majority of customer financing carrying values are concentrated in the following aircraft models:

Note 7 – Other Assets
Sea Launch
At March 31,September 30, 2016 and December 31, 2015, Other assets included $356 of receivables related to our former investment in the Sea Launch venture which became payable by certain Sea Launch partners following Sea Launch’s bankruptcy filing in June 2009. The $356 includes $147 related to a payment made by us under a bank guarantee on behalf of Sea Launch and $209 related to loans (partner loans) we made to Sea Launch. The net amounts owed to Boeing by each of the partners are as follows: S.P. Koroley Rocket and Space Corporation Energia of Russia – $223, PO Yuzhnoye Mashinostroitelny Zavod of Ukraine – $89 and KB Yuzhnoye of Ukraine – $44.
Although each partner is contractually obligated to reimburse us for its share of the bank guarantee, the Russian and Ukrainian partners have raised defenses to enforcement and contested our claims. On February 1, 2013, we filed an action in the United States District Court for the Central District of California seeking reimbursement from the other Sea Launch partners of the $147 bank guarantee payment and the $209 partner loan obligations. On September 28, 2015,May 12, 2016, the district court granted summaryissued a judgment in Boeing’s favor on all claims againstof Boeing relating to the other partners. Further proceedings will determinebank guarantee payment and the final damage amount, including potential interest payments. If the partners decide to appeal or seek reconsideration of the district court’s ruling additional proceedings would ensue.partner loan obligations. Prior to these proceedings, we had filed a Notice of Arbitration with the Stockholm Chamber of Commerce seeking reimbursement from the other partners for a portion of these amounts. In 2010,On May 16, 2016, the arbitrator ruled that the Stockholm Chamber of Commerce lacked jurisdiction to hear the matter, which ruling has been on appealappellate court in Sweden dismissed the Swedish appellate courts since mid-2014. During the fourth quarter of 2015, the Supreme Court of Sweden confirmedproceedings at our rightrequest.
We continue to pursue this appealcollection efforts in connection with the Swedish appellate courts.
Wecourt judgment and continue to believe the partners have the financial wherewithal to pay and intend to pursue vigorously all of our rights and remedies. In the event we are unable to secure reimbursement of $147 related to our payment under the bank guarantee and $209 related to partner loans made to Sea Launch, we could incur additional charges. Our current assessment as to the collectability of these receivables takes into account the current economic conditions in Russia and Ukraine, although we will continue to monitor the situation.

Spirit AeroSystems
As of March 31,September 30, 2016 and December 31, 2015, Other assets included $140 of receivables related to indemnifications from Spirit AeroSystems, Inc. (Spirit), for costs incurred related to pension and retiree medical obligations of former Boeing employees that were subsequently employed by Spirit. During the fourth quarter of 2014, Boeing filed a complaint against Spirit in Delaware Superior Court seeking to enforce our rights to indemnification and to recover from Spirit amounts incurred by Boeing for pension and retiree medical obligations. We expect to fully recover from Spirit.

The liabilities recorded represent our best estimate or the low end of a range of reasonably possible costs expected to be incurred to remediate sites, including operation and maintenance over periods of up to 30 years. It is reasonably possible that we may incur charges that exceed these recorded amounts because of regulatory agency orders and directives, changes in laws and/or regulations, higher than expected costs and/or the discovery of new or additional contamination. As part of our estimating process, we develop a range of reasonably possible alternate scenarios that includes the high end of a range of reasonably possible cost estimates for all remediation sites for which we have sufficient information based on our experience and existing laws and regulations. There are some potential remediation obligations where the costs of remediation cannot be reasonably estimated. At March 31,September 30, 2016 and December 31, 2015, the high end of the estimated range of reasonably possible remediation costs exceeded our recorded liabilities by $873 and $853.

Commercial Aircraft Commitments
In conjunction with signing definitive agreements for the sale of new aircraft (Sale Aircraft), we have entered into trade-in commitments with certain customers that give them the right to trade in used aircraft at a specified price upon the purchase of Sale Aircraft. The probability that trade-in commitments will be exercised is determined by using both quantitative information from valuation sources and qualitative information from other sources. The probability of exercise is assessed quarterly, or as events trigger a change, and takes into consideration the current economic and airline industry environments. Trade-in commitments, which

can be terminated by mutual consent with the customer, may be exercised only during the period specified in the agreement, and require advance notice by the customer.
Trade-in commitment agreements at March 31,September 30, 2016 have expiration dates from 2016 through 2026. At March 31,September 30, 2016, and December 31, 2015 total contractual trade-in commitments were $1,7181,385 and $1,585. As of March 31,September 30, 2016 and December 31, 2015, we estimated that it was probable we would be obligated to perform on certain of these commitments with net amounts payable to customers totaling $248170 and $240 and the fair value of the related trade-in aircraft was $248$170 and $240.
Financing Commitments
Financing commitments, which include commitments to provide financing related to aircraft on order, including options and thoseunder option for deliveries or proposed inas part of sales campaigns, totaled $17,02617,425 and $16,283 as of March 31,September 30, 2016 and December 31, 2015. The estimated earliest potential funding dates for these commitments as of March 31,September 30, 2016 are as follows:

We have concluded that no reserve for future potential losses is required for these financing commitments based upon the terms, such as collateralization and interest rates, under which funding would be provided.
Standby Letters of Credit and Surety Bonds
We have entered into standby letters of credit and surety bonds with financial institutions primarily relating to the guarantee of our future performance on certain contracts. Contingent liabilities on outstanding letters of credit agreements and surety bonds aggregated approximately $4,5414,368 and $4,968 as of March 31,September 30, 2016 and December 31, 2015.
Commitments to ULA
We and Lockheed Martin Corporation have each committed to provide ULA with additional capital contributions in the event ULA does not have sufficient funds to make a required payment to us under an inventory supply agreement. As of March 31,September 30, 2016, ULA’s total remaining obligation to Boeing under the inventory supply agreement was $120. See Note 4.

F/A-18
At March 31,September 30, 2016, our backlog included 4028 F/A-18 aircraft under contract with the U.S. Navy. The Consolidated Appropriations Act, 2016, passed in December 2015, funds 12 additional F/A-18 aircraft that, combined with the orders in backlog, would complete production in mid-2018. The President’s Fiscal Year 2017 Budget request submitted in February 2016 includes funding for two additional F/A-18 aircraft. In MarchMay 2016, both congressional appropriations committees included additional F/A-18s in their proposed FY17 defense funding bills. The Senate bill includes funding for 14 F/A-18s and the House bill includes funding for a total of 16 F/A-18s. On September 28, 2016, the Navy included 14White House approved the proposed sale of up to 40 F/A-18 aircraft in its unfunded priorities list submittedto Kuwait subject to the congressional defense committees for funding consideration.Congressional Notification process. We are continuing to work with our U.S. customers as well as international customers to secure additional orders that would extend the program beyond 2018.

Should additional orders not materialize, it is reasonably possible that we will decide to end production of the F/A-18 in 2018. We are still evaluating the full financial impact of a potential production shutdown, including any recovery that may be available from the U.S. government.
United States Government Defense Environment Overview
The enactment of The Bipartisan Budget Act of 2015 in November 2015 established overall defense spending levels for FY2016 and FY2017. However, uncertainty remains with respect to levels of defense spending for FY2018 and beyond including risk of future sequestration cuts.
Significant uncertainty also continues with respect to program-level appropriations for the U.S. Department of Defense (U.S. DoD) and other government agencies, including the National Aeronautics and Space Administration, within the overall budgetary framework described above. Future budget cuts, including cuts mandated by sequestration, or future procurement decisions associated with the authorization and appropriations process could result in reductions, cancellations and/or delays of existing contracts or programs. Any of these impacts could have a material effect on the results of the Company's operations, financial position and/or cash flows.
In additionOn September 29, 2016 a continuing resolution was enacted to fund the risks described above,U.S. government through December 9, 2016. After this date, if Congress is unable to pass appropriations bills in a timely manner, a government shutdown could result which may have impacts above and beyond those resulting from budget cuts, sequestration impacts or program-level appropriations. For example, requirements to furlough employees in the U.S. DoD or other government agencies could result in payment delays, impair our ability to perform work on existing contracts, and/or negatively impact future orders.
KC-46A Tanker and BDS Fixed-Price Development Contracts
Fixed-price development work is inherently uncertain and subject to significant variability in estimates of the cost and time required to complete the work. BDS fixed-price contracts with significant development work include Commercial Crew, Saudi F-15, USAF KC-46A Tanker and commercial and military satellites. The operational and technical complexities of these contracts create financial risk, which could trigger termination provisions, order cancellations or other financially significant exposure. Changes to cost and revenue estimates could result in lower margins or material charges for reach-forward losses. For example, during the first quarter of 2016, we have recorded additional reach-forward losses of $243$816 on the KC-46A Tanker program.program and a charge of $162 resulting from a reach-forward loss of $38 on the Commercial Crew Program. Moreover, both of these programs remain subject to additional reach-forward losses if we experience further technical or quality issues, schedule delays, or increased costs. 

KC-46A Tanker
In 2015,2011, we began work on low rate initial production aircraft forwere awarded a contract from the U.S. Air Force (USAF). The USAF is expected to authorize two low rate initial production lots in 2016 for a total of 19 aircraft, subject to satisfactory progress being made on thedesign, develop, manufacture and deliver four next generation aerial refueling tankers. This Engineering, Manufacturing and Development contract.(EMD) contract is a fixed-price incentive fee contract valued at $4.9 billion and involves highly complex designs and systems integration. In August 2016, the USAF authorized LRIP lots for 7 and 12 aircraft valued at $2.8 billion. At March 31,September 30, 2016, we had approximately $812$298 of capitalized precontract costs and $1,789$690 of potential termination liabilities to suppliers associated with aircraft we expect USAF to authorize in the USAF KC-46A Tanker.future.
Recoverable Costs on Government Contracts  
Our final incurred costs for each year are subject to audit and review for allowability by the U.S. government, which can result in payment demands related to costs they believe should be disallowed. We work with the U.S. government to assess the merits of claims and where appropriate reserve for amounts disputed. If we are unable to satisfactorily resolve disputed costs, we could be required to record an earnings charge and/or provide refunds to the U.S. government.
Russia/Ukraine
We continue to monitor political unrest involving Russia and Ukraine, where we and some of our suppliers source titanium products and/or have operations. A number of our commercial customers also have operations in Russia and Ukraine. To date, we have not experienced any significant disruptions to production or deliveries. Should suppliers or customers experience disruption, our production and/or deliveries could be materially impacted.

747 Program
During the fourth quarterLower-than-expected demand for large commercial passenger and freighter aircraft and slower-than-expected growth of 2015, we recorded a charge of $885global freight traffic have continued to recognize a reach-forward loss on the 747 program primarily due to slower than expected growth in global cargo markets, resulting indrive market anduncertainties, pricing pressures and fewer orders than anticipated driving reductionsanticipated. As a result, during the second quarter of 2016, we canceled previous plans to return to a production rate of 1.0 aircraft per month beginning in our planned production rates. The charge was primarily related2019, resulting in a reduction in the program accounting quantity from 1,574 to 1,555 aircraft. This reduction in the program accounting quantity, together with lower anticipated revenues reflectingfrom future sales and higher costs associated with producing fewer airplanes, resulted in a reach-forward loss of $1,188 in the second quarter. We previously recognized reach-forward losses of $885 and $70 during the second half of 2015 and the first quarter of 2016, respectively, related to the prior decision to reduce the production rate to 0.5 per month and lower estimated revenue from future sales due to ongoing pricing and market pressures as well as higher estimated costs due topressures. We reduced the reduction in the production rate from 1.0 per month to 0.5 per month in September 2016. The adjusted program accounting quantity includes 27 undelivered aircraft, currently scheduled to be produced through 2019. We currently plancontinue to return to a rate of 1.0 per month in 2019. During the first quarter of 2016, an additional reach-forward loss of $70 was recorded to reflect lower estimated revenue from future sales. We have a number of completed aircraft in inventory as well as unsold production positions and we remain focused on obtaining additional orders and implementing cost-reduction efforts. If we are unable to obtain sufficient orders in 2016 and/or market, production and other risks cannot be mitigated, we could record additional losses that may be material.material, and it is reasonably possible that we could decide to end production of the 747.
787 Program
The 787 program continues to have near breakeven gross margins. The combination of production challenges, change incorporation on early build aircraft, schedule delays, customer and supplier impacts and changes to price escalation factors has created significant pressure on program profitability. If risks related to this program, including risks associated with productivity improvements, supply chain management, planned production rate increases or introducing and manufacturing the 787-10 derivative as scheduled cannot be mitigated, the program could face additional customer claims and/or supplier assertions, as well asrecord a reach-forward loss that may be material.

Note 9 – Arrangements with Off-Balance Sheet Risk
We enter into arrangements with off-balance sheet risk in the normal course of business, primarily in the form of guarantees.
The following table provides quantitative data regarding our third party guarantees. The maximum potential payments represent a “worst-case scenario,” and do not necessarily reflect amounts that we expect to pay. Estimated proceeds from collateral and recourse represent the anticipated values of assets we could liquidate or receive from other parties to offset our payments under guarantees. The carrying amount of liabilities represents the amount included in Accrued liabilities.

Contingent Repurchase Commitments The repurchase price specified in contingent repurchase commitments is generally lower than the expected fair value at the specified repurchase date. Estimated proceeds from collateral/recourse in the table above represent the lower of the contracted repurchase price or the expected fair value of each aircraft at the specified repurchase date.

Indemnifications to ULA In 2006, we agreed to indemnify ULA through December 31, 2020 against potential non-recoverability and non-allowability of $1,360 of Boeing Delta launch program inventory included in contributed assets plus $1,860 of inventory subject to an inventory supply agreement which ends on March 31, 2021. Since inception, ULA has consumed $1,258$1,278 of the $1,360 of inventory that was contributed by us and has yet to consume $102.$82. Under the inventory supply agreement, we have recorded revenues and cost of sales of $1,389$1,436 through March 31,September 30, 2016. ULA has made payments of $1,740 to us under the inventory supply agreement and we have made $63 of net indemnification payments to ULA.
We agreed to indemnify ULA against potential losses that ULA may incur in the event ULA is unable to obtain certain additional contract pricing from the USAF for four satellite missions. We believe ULA is entitled to additional contract pricing. In December 2008, ULA submitted a claim to the USAF to re-price the contract value for two satellite missions. In March 2009, the USAF issued a denial of that claim. In June 2009, ULA filed a notice of appeal, and in October 2009, ULA filed a complaint before the Armed Services Board of Contract Appeals (ASBCA) for a contract adjustment for the price of the two satellite missions. In September 2009, the USAF exercised its option forof these missions, followed in 2011 by a third satellite mission. During the third quartersubsequent notice of 2010, ULA submittedappeal with respect to a claim to the USAF to re-price the contract value of the third mission. The USAF did not exercise an option for a fourth mission prior to the expiration of the contract. In March 2011, ULA filed a noticeDuring the second quarter of appeal before2016, the ASBCA seekingruled that ULA is entitled to re-priceadditional contract pricing for each of the third mission. On November 20, 2013,three missions and remanded to the ASBCA denied USAF motions for summary judgment against ULA in large part, leaving ULA's claims againstparties to negotiate appropriate pricing. However, if the USAF substantially intact. The hearing beforeappeals the ASBCA concluded on December 20, 2013. The parties filed their final post-hearing briefs in May 2014. The ASBCA may now issue a decision at any time. IfASBCA's ruling, and ULA is ultimately unsuccessful in obtaining additional pricing, we may be responsible for an indemnification payment up to $261 and may record up to $277 in pre-tax losses associated with the three missions.

Potential payments for Other Delta contracts include $85 related to deferred support costs and $91 related to deferred production costs. In June 2011, the Defense Contract Management Agency (DCMA) notified ULA that it had determined that $271 of deferred support costs are not recoverable under government contracts. In December 2011, the DCMA notified ULA of the potential non-recoverability of an additional $114 of deferred production costs. ULA and Boeing believe that all costs are recoverable and in November 2011, ULA filed a certified claim with the USAF for collection of deferred support and production costs. The USAF issued a final decision denying ULA’s certified claim in May 2012. On June 14, 2012, Boeing and ULA filed a suit in the Court of Federal Claims seeking recovery of the deferred support and production costs from the U.S. government. On November 9, 2012, the U.S. government filed an answer to our claim and asserted a counterclaim for credits that it alleges were offset by deferred support cost invoices. We believe that the U.S. government’s counterclaim is without merit, and have filed an answer challenging it on multiple grounds. The litigation is in the discovery phase, and the Court has not yet set a trial date. If, contrary to our belief, it is determined that some or all of the deferred support or production costs are not recoverable, we could be required to record pre-tax losses and make indemnification payments to ULA for up to $317 of the costs questioned by the DCMA.
Other Indemnifications In conjunction with our sales of Electron Dynamic Devices, Inc. and Rocketdyne Propulsion and Power businesses and our Commercial Airplanes facilities in Wichita, Kansas and Tulsa and McAlester, Oklahoma, we agreed to indemnify, for an indefinite period, the buyers for costs relating to pre-closing environmental conditions and certain other items. We are unable to assess the potential number of future claims that may be asserted under these indemnifications, nor the amounts thereof (if any). As a result, we cannot estimate the maximum potential amount of future payments under these indemnities and therefore, no liability has been recorded. To the extent that claims have been made under these indemnities and/or are probable and reasonably estimable, liabilities associated with these indemnities are included in the environmental liability disclosure in Note 8.

Credit Guarantees We have issued credit guarantees, principally to facilitate the sale and/or financing of commercial aircraft. Under these arrangements, we are obligated to make payments to a guaranteed party in the event that lease or loan payments are not made by the original lessee or debtor or certain specified services are not performed. A substantial portion of these guarantees has been extended on behalf of original lessees or debtors with less than investment-grade credit. Our commercial aircraft credit guarantees are collateralized by the underlying commercial aircraft and certain other assets. Current outstanding credit guarantees expire within the next fivefour years.
Note 10 – Debt
On May 18, 2016, we issued $1,200 of fixed rate senior notes consisting of $400 due June 15, 2023 that bear an annual interest rate of 1.875%, $400 due June 15, 2026 that bear an annual interest rate of 2.25%, and $400 due June 15, 2046 that bear an annual interest rate of 3.375%. The notes are unsecured senior obligations and rank equally in right of payment with our existing and future unsecured and unsubordinated indebtedness. The net proceeds of the issuance totaled $1,170, after deducting underwriting discounts, commissions and offering expenses.

Note 1112 – Share-Based Compensation and Other Compensation Arrangements
Restricted Stock Units
On February 22, 2016, we granted to our executives 777,837 restricted stock units (RSUs) as part of our long-term incentive program with a grant date fair value of $117.50 per unit. The RSUs granted under this program will vest and settle in common stock (on a one-for-one basis) on the third anniversary of the grant date.
Performance-Based Restricted Stock Units
On February 22, 2016, we granted to our executives 721,176 performance-based restricted stock units (PBRSUs) as part of our long-term incentive program with a grant date fair value of $126.74 per unit. Compensation expense for the award is recognized over the three-year performance period based upon the grant date fair value estimated using a Monte-Carlo simulation model. The model used the following assumptions: expected volatility of 22.44% based upon historical stock volatility, a risk-free interest rate of 0.92%, and no expected dividend yield because the units earn dividend equivalents.

Performance Awards
On February 22, 2016, we granted to our executives performance awards as part of our long-term incentive program with a payout based on the achievement of financial goals for the three-year period ending December 31, 2018. At March 31,September 30, 2016, the minimum payout amount is $0 and the maximum amount we could be required to pay out is $364.$344.

These are included in the net periodic pension cost of which a portion is allocated to production as inventoried costs. See Note 10.11.

Note 1314 – Derivative Financial Instruments
Cash Flow Hedges
Our cash flow hedges include foreign currency forward contracts and commodity purchase contracts. We use foreign currency forward contracts to manage currency risk associated with certain transactions, specifically forecasted sales and purchases made in foreign currencies. Our foreign currency contracts hedge forecasted transactions through 2021. We use commodity derivatives, such as fixed-price purchase commitments to hedge against potentially unfavorable price changes for items used in production. Our commodity contracts hedge forecasted transactions through 2020.
Fair Value Hedges
Interest rate swaps under which we agree to pay variable rates of interest are designated as fair value hedges of fixed-rate debt. The net change in fair value of the derivatives and the hedged items is reported in Boeing Capital interest expense.
Derivative Instruments Not Receiving Hedge Accounting Treatment
We have entered into agreements to purchase and sell aluminum to address long-term strategic sourcing objectives and international business requirements. These agreements are derivative instruments for accounting purposes. The quantities of aluminum in these agreements offset and are priced at prevailing market prices. We also hold certain foreign currency forward contracts which do not qualify for hedge accounting treatment.

Based on our portfolio of cash flow hedges, we expect to reclassify losses of $12370 (pre-tax) out of Accumulated other comprehensive loss into earnings during the next 12 months. Ineffectiveness related to our hedges recognized in Other income was insignificant for the nine and three months ended March 31,September 30, 2016 and 2015.
We have derivative instruments with credit-risk-related contingent features. For foreign exchange contracts with original maturities of at least five years, our derivative counterparties could require settlement if we default on our five-year credit facility. For certain commodity contracts, our counterparties could require collateral posted in an amount determined by our credit ratings. The fair value of foreign exchange and commodity contracts that have credit-risk-related contingent features that are in a net liability position at March 31,September 30, 2016 was $42. At March 31,September 30, 2016, there was no collateral posted related to our derivatives.

Note 1415 – Fair Value Measurements
The fair value hierarchy 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.The following table presents our assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy.

Money market funds, available-for-sale debt investments and equity securities are valued using a market approach based on the quoted market prices or broker/dealer quotes of identical or comparable instruments.
Derivatives include foreign currency, commodity and interest rate contracts. Our foreign currency forward contracts are valued using an income approach based on the present value of the forward rate less the contract rate multiplied by the notional amount. Commodity derivatives are valued using an income approach based on the present value of the commodity index prices less the contract rate multiplied by the notional amount. The fair value of our interest rate swaps is derived from a discounted cash flow analysis based on the terms of the contract and the interest rate curve.
Certain assets have been measured at fair value on a nonrecurring basis using significant unobservable inputs (Level 3). The following table presents the nonrecurring losses recognized for the threenine months ended March 31September 30 due to long-lived asset impairment and the fair value and asset classification of the related assets as of the impairment date:

The fair value of the impaired operating lease equipment is derived by calculating a median collateral value from a consistent group of third party aircraft value publications. The values provided by the third party aircraft publications are derived from their knowledge of market trades and other market factors. Management reviews the publications quarterly to assess the continued appropriateness and consistency with market trends. Under certain circumstances, we adjust values based on the attributes and condition of the specific aircraft or equipment, usually when the features or use of the aircraft vary significantly from the more generic

aircraft attributes covered by third party publications, or on the expected net sales price for the aircraft. Property, plant and equipment and Acquired intangible assets were primarily valued using an income approach based on the discounted cash flows associated with the underlying assets.
For Level 3 assets that were measured at fair value on a nonrecurring basis during the threenine months ended March 31,September 30, 2016,, the following table presents the fair value of those assets as of the measurement date, valuation techniques and related unobservable inputs of those assets.

The fair value of Accounts receivable is based on current market rates for loans of the same risk and maturities. The fair values of our variable rate notes receivable that reprice frequently approximate their carrying amounts. The fair values of fixed rate notes receivable are estimated with discounted cash flow analysis using interest rates currently offered on loans with similar terms to borrowers of similar credit quality. The fair value of our debt that is traded in the secondary market is classified as Level 2 and is based on current market yields. For our debt that is not traded in the secondary market, the fair value is classified as Level 2 and is based on our indicative borrowing cost derived from dealer quotes or discounted cash flows. The fair values of our debt classified as Level 3 are based on discounted cash flow models using the implied yield

from similar securities. With regard to other financial instruments with off-balance sheet risk, it is not practicable to estimate the fair value of our indemnifications and financing commitments because the amount and timing of those arrangements are uncertain. Items not included in the above disclosures include cash, restricted cash, time deposits and other deposits, commercial paper, money market funds, Accounts payable and long-term payables. The carrying values of those items, as reflected in the Condensed Consolidated Statements of Financial Position, approximate their fair value at March 31,September 30, 2016 and December 31, 2015.2015. The fair value of assets and liabilities whose carrying value approximates fair value is determined using Level 2 inputs, with the exception of cash (Level 1).
Note 1516 – Legal Proceedings
Various legal proceedings, claims and investigations related to products, contracts, employment and other matters are pending against us. Potentially material contingencies are discussed below.
WeIn addition, we are subject to various U.S. government inquiries and investigations from which civil, criminal or administrative proceedings could result or have resulted in the past. Such proceedings involve or could involve claims by the government for fines, penalties, compensatory and treble damages, restitution and/or forfeitures. Under government regulations, a company, or one or more of its operating divisions or subdivisions, can also be suspended or debarred from government contracts, or lose its export privileges, based on the results of investigations. We believe, based upon current information, that the outcome of any such legal proceeding, claim, or government disputesdispute and investigationsinvestigation will not have a material effect on our financial position, results of operations, or cash flows. Where it is reasonably possible that we will incur losses in excess of recorded amounts in connection with any of the matters set forth below, we will disclose either the amount or range of reasonably possible losses in excess of such amounts or, where no such amount or range can be reasonably estimated, the reasons why no such estimate can be made.
Employment, Labor and Benefits Litigation
On October 13, 2006, we were named as a defendant in a lawsuit filed in the U.S. District Court for the Southern District of Illinois. Plaintiffs, seeking to represent a class of similarly situated participants and beneficiaries in The Boeing Company Voluntary Investment Plan (the VIP), alleged that fees and expenses incurred by the VIP were and are unreasonable and excessive, not incurred solely for the benefit of the VIP and its participants, and were undisclosed to participants. Plaintiffs further alleged that defendants breached their fiduciary duties in violation of §502(a)(2) of ERISA, and sought injunctive and equitable relief pursuant to §502(a)(3) of ERISA. The parties reached a provisional settlement on August 26, 2015. The court approved the settlement, as well as the plaintiffs’ motion for award of attorneys’ fees in a fairness hearing on March 30, 2016. The settlement did not materially affect our financial position, results of operations or cash flows.
Note 1617 – Segment Information
Effective during the first quarter of 2016, certain programs were realigned between Boeing Military Aircraft and Global Services & Support segments. Business segment data for 2015 have been adjusted to reflect the realignment.
Our primary profitability measurements to review a segment’s operating results are Earnings from operations and operating margins. See page 6 for a Summary of Business Segment Data, which is an integral part of this note.

Unallocated Pension and Other Postretirement Benefit Expense
Unallocated pension and other postretirement benefit expense represent the portion of pension and other postretirement benefit costs that are not recognized by business segments for segment reporting purposes. Pension costs, comprising Generally Accepted Accounting Principles in the United States of America (GAAP) (GAAP) service and prior service costs, are allocated to Commercial Airplanes. Pension costs are allocated to BDS using U.S. Government Cost Accounting Standards (CAS), which employ different actuarial assumptions and accounting conventions than GAAP. These costs are allocable to government contracts. Other postretirement benefit costs are allocated to business segments based on CAS, which is generally based on benefits paid.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Shareholders of
The Boeing Company
Chicago, Illinois
We have reviewed the accompanying condensed consolidated statement of financial position of The Boeing Company and subsidiaries (the “Company”) as of March 31,September 30, 2016, and the related condensed consolidated statements of operations and comprehensive income for the three-month and nine-month periods ended September 30, 2016 and 2015, and the related condensed consolidated statements of cash flows and equity for the three-monthnine-month periods ended March 31,September 30, 2016 and 2015. These interim financial statements are the responsibility of the Company’s management.
We conducted our reviews in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.
Based on our reviews, we are not aware of any material modifications that should be made to such condensed consolidated interim financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.
We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated statement of financial position of the Company as of December 31, 2015, and the related consolidated statements of operations, comprehensive income, equity, and cash flows for the year then ended (not presented herein); and in our report dated February 10, 2016, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated statement of financial position as of December 31, 2015 is fairly stated, in all material respects, in relation to the consolidated statement of financial position from which it has been derived.

Earnings from operations for the nine months ended September 30, 2016 decreased by $2,631 million compared with the same period in 2015 due to lower earnings at Commercial Airplanes, partially offset by lower unallocated pension and postretirement expense. Commercial Airplanes earnings for the nine months ended September 30, 2016 decreased by $2,934 million due to the reach-forward losses on the 747 program of $1,258 million recorded during the first half of 2016, the reclassification of $1,235 million of 787 flight test aircraft costs, as well as lower volume and mix. During the second quarter of 2016, we reclassified $1,235 million of costs to research and development related to two 787 flight test aircraft as a result of our determination that those aircraft are no longer commercially saleable.
During the first half of 2016, we recorded reach-forward losses of $816 million on the KC-46A Tanker program of which $516 million was recorded at Commercial Airplanes and $300 million at our BMA segment. During the second quarter of 2015, we recorded KC-46A Tanker program reach-forward losses $835 million of which $513 million was recorded at Commercial Airplanes and $322 million at our BMA segment.
Earnings from operations for the three months ended March 31,September 30, 2016 decreased by $231$298 million. Commercial Airplanes earnings decreased $171 million compared withprimarily due to lower volume and mix, offset by lower period costs. BDS earnings from operations for the same period in 2015three months ended September 30, 2016 decreased by $238 million, primarily reflectingdue to lower earnings at Commercial Airplanes,in the N&SS and BMA segments, partially offset by higher earnings in the changes inGS&S segment.
The earnings decreases for the nine and three months ended September 30, 2016 are offset by unallocated pension and other postretirement benefit income recorded in 2016 compared with expense and unallocated items and eliminations.
Duringrecorded in the first quarter of 2016, we recorded a reach-forward loss of $243 million on the KC-46A Tanker program of which $162 million was recorded at Commercial Airplanes and $81 million at our Boeing Military Aircraft (BMA) segment. In addition, we recorded a charge of $70 million related to the 747 program at Commercial Airplanes.comparable prior year periods.
Core operating earnings for the threenine months ended March 31,September 30, 2016 decreased by $438$3,082 million compared with the same period in 2015 primarily due to the 747 charges and the reclassification of costs related to the 787 flight test aircraft described above, as well as delivery mix at Commercial Airplanes. Core operating earnings for the three months ended September 30, 2016 decreased by $443 million due to lower earnings at N&SS and Commercial Airplanes.

The decrease in net periodic pension benefit cost for the nine and three months ended March 31,September 30, 2016 of $514$1,631 million and $569 million compared with the same periodperiods in 2015 is primarily due to lower service costs and lower amortization of actuarial losses driven by higher discount rates.losses. The lower service costs reflect the changes to our retirement plans whereby certain employees transitioned in 2016 to a company-funded defined contribution retirement savings plan. The lower amortization of actuarial losses reflects actuarial gains in 2015 resulting from the year-end discount rate increase from 3.9% to 4.2%. In 2014, the discount rate decreased to 3.9% from 4.8% resulting in actuarial losses.

A portion of net periodic benefit cost is recognized in Earnings from operations in the period incurred and the remainder is included in inventory at the end of the reporting period and recorded in Earnings from operations in subsequent periods. Costs are allocated to the business segments as described in Note 16.17. Net periodic pension benefit costs included in Earnings from operations were as follows:

Total Costs and Expenses (“Cost of Sales”)
Cost of sales, for both products and services, consists primarily of raw materials, parts, sub-assemblies, labor, overhead and subcontracting costs. Our Commercial Airplanes segment predominantly uses program accounting to account for cost of sales and BDS predominantly uses contract accounting. Under program accounting, cost of sales for each commercial airplane program equals the product of (i) revenue recognized in connection with customer deliveries and (ii) the estimated cost of sales percentage applicable to the total remaining program. Under contract accounting, the amount reported as cost of sales is determined by applying the estimated cost of sales percentage to the amount of revenue recognized. The following table summarizes cost of sales:

Contractual backlog of unfilled orders excludes purchase options, announced orders for which definitive contracts have not been executed, and unobligated U.S. and non-U.S. government contract funding. The decrease in contractual backlog during the threenine months ended March 31,September 30, 2016 compared with December 31, 2015 was primarily due to deliveries in excess of net orders.
Unobligated backlog includes U.S. and non-U.S. government definitive contracts for which funding has not been authorized. The unobligated backlog of $9,766$13,115 million at March 31,September 30, 2016 decreased increased from December 31, 2015 primarily due to contract awards, partially offset by reclassifications to contractual backlog related to incremental funding for BDS contracts, partially offset by contract awards.contracts.
Additional Considerations
KC-46A Tanker In 2011, we were awarded a contract from the U.S. Air Force (USAF) to design, develop, manufacture and deliver four next generation aerial refueling tankers. The KC-46A Tanker is a derivative of our 767 commercial aircraft. This Engineering, Manufacturing and Development (EMD) contract is a fixed-price incentive fee contract valued at $4.9 billion and involves highly complex designs and systems integration. The EMD contract is currently in the certification and flight testing phases. In 2015, we began work on low rate initial production (LRIP) aircraft for the USAF. During the third quarter, following our achievement of key flight testing milestones, the USAF authorized two LRIP lots for 7 and have continued production of LRIP12 aircraft in 2016. The USAF is expected to authorize two low rate initial production lots in 2016 for a total of 19 aircraft, subject to satisfactory progress being made on the EMD contract.valued at $2.8 billion.
Through 2015, we recorded reach-forward losses of $1,095$1,260 million onrelated to the EMD contract and in 2015, we recorded a reach-forward loss of $165 million related to LRIP aircraft. The EMD losses were primarily due to initial engineering and design issues, design changes required inIn the aircraft fuels and aerial refueling systems, additional qualification and certification testing as well as investment to enable us to meet our delivery commitments in 2017. The reach-forward loss related to LRIP aircraft was primarily driven by increased manufacturing complexity resulting from design changes. Infirst quarter of 2016, we recorded further reach-forward losses of $243 million which included $158 million related to the EMD contract and $85 million related to LRIP aircraft. These losses arewere primarily driven by higher than anticipated certification and test rework and the change incorporation impact to EMD and LRIP aircraft. In the second quarter of 2016, technical complexities and schedule delays resulted in additional charges of $573 million for reach-forward losses. The second quarter charges were driven by

costs associated with certification delays and higher costs associated with the overall revised schedule, as well as a boom axial load issue that required a hardware solution, and production concurrency between late-stage development testing and the initial production aircraft. As with any development program, this program remains subject to additional reach-forward losses if we experience further technical or quality issues, schedule delays or increased costs.
We continueThe first tanker delivery is expected to expect to meet our commitment to deliveroccur in late 2017 with 18 fully operational aircraft to the customer by August 2017.be delivered in early 2018. The contract contains production options for both LRIP aircraft and full rate production aircraft. If all options under the contract are exercised, we expect to deliver 179 aircraft for a total expected contract value of approximately $30 billion.
Russia/Ukraine We continue to monitor political unrest involving Russia and Ukraine, where we and some of our suppliers source titanium products and/or have operations. A number of our commercial customers also have operations in Russia and Ukraine. To date, we have not experienced any significant disruptions to production or deliveries. Should suppliers or customers experience disruption, our production and/or deliveries could be materially impacted.

Export-Import Bank of the United States Many of our non-U.S. customers finance purchases through the Export-Import Bank of the United States. Following the expiration of the bank’s charter on June 30, 2015, the bank’s charter was reauthorized in December 2015. The bank is now authorized through September 30, 2019. However, until the U.S. Senate confirms members sufficient to reconstitute a quorum of the bank’s board of directors, the bank will not be able to approve any transaction totaling more than $10 million. As a result, we may fund additional commitments and/or enter into new financing arrangements with customers. Certain of our non-U.S. customers also may seek to delay purchases if they cannot obtain financing at reasonable costs, and there may be further impacts with respect to future sales campaigns involving non-U.S. customers. We continue to work with our customers to mitigate risks associated with the lack of a quorum of the bank’s board of directors and assist with alternative third party financing sources.
Segment Results of Operations and Financial Condition
Commercial Airplanes
Business Environment and Trends
Airline Industry Environment
Our updated 20-year forecast, published in July 2016, projects a long-term average growth rate of 4.8% per year for passenger traffic and 4.2% for cargo traffic. Based on long-term global economic growth projections of 2.9% average annual GDP growth, we project a $5.9 trillion market for approximately 39,600 new airplanes over the next 20 years. We continue to monitor near-term market conditions in the wide-body segment. If sufficient wide-body orders do not materialize in the next several quarters, we may consider appropriate adjustments to our production rates.

The decrease in earnings and operating margins is primarily due to delivery mix, an additional reach-forward loss related to the KC-46A Tanker program of $162 million, higher research and development costs of $128$1,481 million primarilyand a reach-forward loss of $1,258 million on the 747 program, as well as lower volume and mix. Research and development costs reflect the reclassification from inventory to research and development expense of $1,235 million related to the fourth and fifth 787 flight test aircraft and higher planned costs related to the 777X program. Earnings include reach-forward losses related to the KC-46A Tanker of $516 million recorded in the first half of 2016 compared with $513 million in the comparable period of 2015.
Earnings from operations for the three months ended September 30, 2016 decreased by $171 million compared with the same period in 2015 primarily due to lower volume and an additional reach-forward loss on the 747 program of $70 million.

mix, offset by lower period costs.
Backlog
The decrease in contractual backlog during the threenine months ended March 31,September 30, 2016 was due to deliveries in excess of net orders.

Program Highlights
737 Program The accounting quantity for the 737 program increased by 200 units during the three months ended March 31,September 30, 2016 and by 600 units during the nine months ended September 30, 2016 due to the program’s normal progress of obtaining additional orders and delivering airplanes. We are currently producing at a rate of 42 per month and plan to increase to 47 per month in 2017. We plan to further increase the rate to 52 per month in 2018 and to 57 per month in 2019. First delivery of the 737 MAX is expected in 2017.
747 Program Lower-than-expected demand for large commercial passenger and freighter aircraft and slower-than-expected growth of global freight traffic have resulted incontinued to drive market uncertainties, ongoing pricing pressures and fewer orders than anticipated. DuringAs a result, during the second quarter of 2016, we canceled previous plans to return to a production rate of 1.0 aircraft per month beginning in 2019, resulting in a reduction in the program accounting quantity from 1,574 to 1,555 aircraft. This reduction in the program accounting quantity, together with lower anticipated revenues from future sales and higher costs associated with producing fewer airplanes, resulted in a reach-forward loss of $1,188 million in the second quarter. We previously recognized reach-forward losses of $885 million and $70 million during the second half of 2015 and the cargo market recovery slowed, and in Januaryfirst quarter of 2016, we announced a planrespectively, related to our prior decision to reduce the production rate to 0.5 per month as well as recognize a reach-forward loss of $885 million on the program. The charge, which was recorded during the fourth quarter of 2015, was primarily related to lower anticipated revenues reflecting ongoing pricing and market pressures, as well as higher estimated costs due to the reduced production rate. During the first quarter of 2016, an additional reach-forward loss of $70 million was recorded to reflectanticipating lower estimated revenue from future sales.sales due to ongoing pricing and market pressures. We are currently producing at areduced the rate offrom 1.0 per month, and expect to further reduce the rate to 0.5 per month in September 2016 and then return2016. The adjusted program accounting quantity includes 27 undelivered aircraft, currently scheduled to 1.0 per month inbe produced through 2019. We continue to have a number of completed aircraft in inventory as well as unsold production positions and we remain focused on obtaining additional orders and implementing cost-reduction efforts. If we are unable to obtain sufficient orders in 2016 and/or market, production and other risks cannot be mitigated, we could record additional losses that may be material.material, and it is reasonably possible that we could decide to end production of the 747.

767 Program The accounting quantity for the 767 program increased by 12 units during the nine months ended September 30, 2016 due to the program’s normal progress of obtaining additional orders and delivering airplanes. The 767 assembly line includes a 767 derivative to support the tanker program. We increased the combined tanker and commercial production rate from 1.5 per month to 2 per month in April of 2016. We plan to further increase the rate to 2.5 per month in the fourth quarter of 2017.

777 Program We are currently producing at a rate of 8.3 per month and plan to reduce the rate to 7 per month in 2017. In the fourth quarter of 2013, we launched the 777X, which features a new composite wing, new engines and folding wing-tips. The 777X will have a separate program accounting quantity, which will be determined in the year of first airplane delivery, targeted for 2020.
787 Program We continue to produceDuring the second quarter of 2016, we began producing at a rate of 10 per month and are in the process of increasing to 12 per month in 2016.month. We are planning a further rate increase to 14 per month by the end of the decade. First delivery of the 787-10 derivative aircraft is targeted for 2018. The accounting quantity of 1,300 units remains unchanged.
We remain focused on implementing the production rate of 12 per monthimproving productivity and improving productivity.obtaining additional orders to support planned production. We continue to monitor and address challenges associated with aircraft production and assembly for both the 787-8 and 787-9, including management of our manufacturing operations and extended global supply chain, completion and integration of traveled work, as well as completing and delivering early build aircraft. In addition, we continue to work with our customers and suppliers to assess the specific impacts of schedule changes, including requests for contractual relief related to delivery delays and supplier assertions.
During 2009, we concluded that the first three flight-test 787 aircraft could not be sold as previously anticipated due to the inordinate amount of rework and unique and extensive modifications made to those aircraft. As a result, costs associated with thesethose airplanes were included in research and development expense. BasedWe produced the fourth and fifth flight test aircraft in 2009 but have been unable to sell them at acceptable prices. The aircraft have been used extensively for flight and ground testing and we intended to begin to refurbish the aircraft in early 2017 for commercial sale based on sales activity and market interestinterest. However, during the second quarter of 2016 we continuedetermined that firm orders for these aircraft prior to believerefurbishment were now unlikely, and that the remaining 787 flight-testCompany would not invest company funds for their refurbishment. The Company also determined the costs to refurbish the aircraft at a future date would be prohibitively expensive. We have therefore determined that the aircraft are not commercially saleable, and we continue to includeaccordingly, costs related toof $1,235 million associated with these aircraft inwere reclassified from 787 program inventory. However, there is risk that we may be unable to sell these aircraft. If we determine that any of the remaining flight test aircraft cannot be sold, we would incur additional material charges related to the reclassification of costs associated with those aircraftinventory to research and development expense.expense during the second quarter of 2016. We have firm orders for the six remaining undelivered early build aircraft and plan to complete retrofitting them by the end of 2017.
The combination of production challenges, change incorporation on early build aircraft, schedule delays, customer and supplier impacts and changes to price escalation factors has created significant pressure on program profitability and we continue to have near breakeven gross margins. If risks related to these challenges, together with risks associated with planned production rate increases and productivity improvements, supply chain management or introducing or manufacturing the 787-10 derivative as scheduled cannot be mitigated, the program could face additional customer claims and/or supplier assertions, further pressures on program profitability and/or a reach-forward loss. We continue to implement mitigation plans and cost-reduction efforts to improve program profitability and address program risks.
Additional Considerations
The development and ongoing production of commercial aircraft is extremely complex, involving extensive coordination and integration with suppliers and highly-skilled labor from thousands of employees and other partners. Meeting or exceeding our performance and reliability standards, as well as those of customers and regulators, can be costly and technologically challenging. In addition, the introduction of new aircraft and derivatives, such as the 787-10, 737 MAX and 777X, involves increased risks associated with meeting development, production and certification schedules. As a result, our ability to deliver aircraft on time, satisfy performance and reliability standards and achieve or maintain, as applicable, program profitability is subject to significant risks. Factors that could result in lower margins (or a material charge if an airplane program has or is determined to have reach-forward losses) include the following: changes to the program accounting quantity, customer and model mix, production costs and rates, changes to price escalation factors due to changes in the inflation rate or other economic indicators, performance or reliability issues involving completed aircraft, capital expenditures and other costs associated with increasing or adding new production capacity, learning curve, additional change incorporation, achieving anticipated cost reductions, flight test and certification schedules, costs, schedule and demand for new airplanes and derivatives and status of customer claims, supplier assertions and other contractual negotiations. While we believe the cost and

revenue estimates incorporated in the consolidated financial statements are appropriate, the technical complexity of our airplane programs creates financial risk as additional completion costs may become

necessary or scheduled delivery dates could be extended, which could trigger termination provisions, order cancellations or other financially significant exposure.
Defense, Space & Security
Business Environment and Trends
United States Government Defense Environment Overview The enactment of The Bipartisan Budget Act of 2015 in November 2015 established overall defense spending levels for FY2016 and FY2017. However, uncertainty remains with respect to levels of defense spending for FY2018 and beyond, including risk of future sequestration cuts.
Significant uncertainty also continues with respect to program-level appropriations for the U.S. Department of Defense (U.S. DoD) and other government agencies, including the National Aeronautics and Space Administration, within the overall budgetary framework described above. Future budget cuts, including cuts mandated by sequestration, or future procurement decisions associated with the authorization and appropriations process could result in reductions, cancellations and/or delays of existing contracts or programs. Any of these impacts could have a material effect on the results of the Company's operations, financial position and/or cash flows.
In additionOn September 29, 2016 a continuing resolution was enacted to fund the risks described above,U.S. government through December 9, 2016. After this date, if Congress is unable to pass appropriations bills in a timely manner, a government shutdown could result which may have impacts above and beyond those resulting from budget cuts, sequestration impacts or program-level appropriations. For example, requirements to furlough employees in the U.S. DoD or other government agencies could result in payment delays, impair our ability to perform work on existing contracts, and/or negatively impact future orders.

Since our operating cycle is long-term and involves many different types of development and production contracts with varying delivery and milestone schedules, the operating results of a particular year, or year-to-year comparisons of revenues, earnings and backlog may not be indicative of future operating results. In addition, depending on the customer and their funding sources, our orders might be structured as annual follow-on contracts, or as one large multi-year order or long-term award. As a result, period-to-period comparisons of backlog are not necessarily indicative of future workloads. The following discussions of comparative results among periods should be viewed in this context.

BDS earnings from operations for the three months ended September 30, 2016 decreased by $238 million compared with the same period in 2015 due to lower earnings of $210 million and $60 million in the N&SS and BMA segments, partially offset by lowerhigher earnings of $19$32 million in the Network & Space Systems (N&SS)GS&S segment.
Backlog
BDS total backlog was $56,313$53,023 million at March 31,September 30, 2016,, reflecting a decrease of 2%8% from December 31, 2015. For further details on the changes between periods, refer to the discussions of the individual segments below.
Additional Considerations
Our BDS business includes a variety of development programs which have complex design and technical challenges. Many of these programs have cost-type contracting arrangements. In these cases, the associated financial risks are primarily in reduced fees, lower profit rates or program cancellation if cost, schedule or technical performance issues arise. Examples of these programs include Ground-based Midcourse Defense (GMD) (GMD), Proprietary and Space Launch System (SLS) programs. Some of our development programs are contracted on a fixed-price basis. Many of these programs have highly complex designs. As technical or quality issues arise during development, we may experience schedule delays and cost impacts, which could increase our estimated cost to perform the work or reduce our estimated price, either of which could result in a material charge or otherwise adversely affect our financial condition. These programs are ongoing, and while we believe the cost and fee estimates incorporated in the financial statements are appropriate, the

technical complexity of these programs creates financial risk as additional completion costs may become necessary or scheduled delivery dates could be extended, which could trigger termination provisions, the loss of satellite in-orbit incentive payments, or other financially significant exposure. These programs have risk for reach-forward losses if our estimated costs exceed our estimated contract revenues. Examples of significant fixed-price development programs include Saudi F-15, USAF KC-46A Tanker, Commercial Crew and commercial and military satellites.

Revenue and cost estimates for all significant contracts are reviewed and reassessed quarterly. Changes in these estimates could result in recognition of cumulative catch-up adjustments to the contract’s inception-to-date revenues, cost of sales and profit, in the period in which such changes are made. Changes in revenue and cost estimates could also result in a reach-forward loss or an adjustment to a reach-forward loss, which would be recorded immediately in earnings. For the nine and three months ended March 31,September 30, 2016, net unfavorable cumulative catch-up adjustments, including reach-forward losses, across all BDS contracts decreased Earnings from operations by $127 million and $56 million. For the nine months and three months ended September 30, 2015 net favorable cumulative catch-up adjustments, including reach-forward losses, across all BDS contracts increased Earnings from operations by $78$129 million and $130$210 million.

Revenues
N&SS revenues for the threenine months ended March 31, 2016 were consistent with the same period in 2015 primarily due to higher volume of $154 million on several missile defense systems and SLS programs, partially offset by lower volume on Electronic and Information Solutions and proprietary programs as well as lower milestone revenues on government satellite programs.
Earnings From Operations
N&SS earnings from operations for the three months ended March 31,September 30, 2016 decreased by $19$551 million compared with the same period in 2015 primarily due to lower revenue related to the Commercial Crew program, lower milestone revenue on government satellite programs, and lower volume on proprietary and Electronic and Information Solutions (E&IS) programs, partially offset by higher volume on the SLS program.
N&SS revenues for the three months ended September 30, 2016 decreasedby $426 million compared with the same period in 2015 due to lower revenues on the Commercial Crew program, lower volume on proprietary programs, and lower milestone revenue on commercial satellite programs.
Lower revenues on the Commercial Crew program for the nine and three months ended September 30, 2016 were largely driven by unfavorable cumulative catch-up adjustments.
Earnings From Operations
N&SS earnings from operations for the nine months ended September 30, 2016 decreased by $227 million compared with the same period in 2015 primarily due to a charge of $162 million on the Commercial Crew program, partially offset by higher earnings related to our United Launch Alliance (ULA) joint venture. In the three months ended March 31, 2016, net favorable cumulative contract catch-up adjustments were $14 millionprimarily due to favorable adjustments on proprietary programs.

N&SS earnings from operations for the three months ended September 30, 2016 decreased by $210 million compared with the same period in 2015. This was primarily due to a Commercial Crew charge of $162 million, largely driven by delays in completion of engineering and supply chain activities, and includes $124 million reversal of cumulative earnings recorded in prior periods and $38 million reach-forward loss. Net unfavorable cumulative contract catch-up adjustments, including reach-forward losses, were $143 million higher in the three months ended September 30, 2016 than in the same period in 2015 primarily reflecting the charge on the Commercial Crew program.

BCC’sBCC’s customer financing and investment portfolio at March 31,September 30, 2016 decreased increased from December 31, 2015 primarily due to new volume of $919 million more than offsetting note payoffs, asset sales and portfolio run-off. At March 31, 2016 and December 31, 2015, BCC had $34 million and $49 million of assets that were held for sale or re-lease, of which $7 million in 2016 had either signed preliminary agreements with deposits or firm contracts to be sold or placed on lease. In addition, aircraft subject to leases with a carrying value of approximately $26 million are scheduled to be returned off lease in the next 12 months. We are seeking to remarket these aircraft or have the leases extended.
BCC enters into certain transactions with Boeing, reflected in Unallocated items, eliminations and other, in the form of intercompany guarantees and other subsidies that mitigate the effects of certain credit quality or asset impairment issues on the BCC segment.

Operating Activities Net cash provided by operating activities was $1.2$7.7 billion during the threenine months ended March 31,September 30, 2016 compared with $0.1$6.2 billion in the same period in 2015,, an increase of $1.1 billion1.5 billion. The year-over-year improvement primarily due toreflects lower inventory growth. Our investment in gross inventories increased by $0.4 billion during the three months ended March 31, 2016 driven by continued investment in commercial airplane program inventory and KC-46A Tanker capitalized precontract costs, partially offset by lower inventory at our BDS business. Our investment in gross inventories in the three months ended March 31, 2015 increased by $2.2 billion driven by continued investment inexpenditures on commercial airplane program inventory, primarily 787. Advances and progress billings remained consistentbalances decreased by $1.8 billion during the threenine months ended March 31, 2016 and 2015.September 30, 2016.
Investing Activities Cash used by investing activities was $0.4$2.0 billion during the threenine months ended March 31,September 30, 2016 compared with $0.2$1.0 billion during the same period in 2015,, largely due to timing of payments for capital expenditures.lower net proceeds from investments in time deposits. We expect capital expenditures in 2016 to be consistent with higher than 2015 due to continued investment to support growth.

Financing Activities Cash used by financing activities was $4.2$8.0 billion during the threenine months ended March 31,September 30, 2016 compared with $2.9$7.6 billion in the same period in 2015, primarily due to higher share repurchases and dividend payments, partially offset by higher new borrowings and lower proceeds from stock options exercised.debt repayments. During the nine months ended September 30, 2016 we issued $1.3 billion of debt compared with $0.8 billion during the same period in 2015. At March 31,September 30, 2016, the recorded balance of debt was $10.0$10.5 billion of which $1.2$0.6 billion was classified as short-term. This includes $2.4 billion of debt attributable to BCC, the vast majority of which $0.5 billion was classified as short-term.long-term.
During the threenine months ended March 31,September 30, 2016, we repurchased 28.651.4 million shares totaling $3.5$6.5 billion through our open market share repurchase program. In addition, 0.6$0.7 million shares were transferred to us from employees for tax withholdings. At March 31,September 30, 2016, the amount available under the share repurchase plan, announced on December 14, 2015, totaled $10.5$7.5 billion.
Capital Resources We have substantial borrowing capacity. Any future borrowings may affect our credit ratings and are subject to various debt covenants as described below. We have a commercial paper program that continues to serve as a significant potential source of short-term liquidity. Throughout the threenine months ended March 31,September 30, 2016, we had no commercial paper borrowings outstanding. Currently, we have $5.0 billion of unused borrowing capacity on revolving credit line agreements. We anticipate that these credit lines will primarily serve as backup liquidity to support our general corporate borrowing needs.
Financing commitments totaled $17.0$17.4 billion and $16.3$16.3 billion at March 31,September 30, 2016 and December 31, 2015.2015. We anticipate that we will not be required to fund a significant portion of our financing commitments as we continue to work with third party financiers to provide alternative financing to customers. Historically, we have not been required to fund significant amounts of outstanding commitments. However, there can be no assurances that we will not be required to fund greater amounts than historically required. In addition, many

of our non-U.S. customers finance aircraft purchases through the Export-Import Bank of the United States. Following the expiration of the bank’s charter on June 30, 2015, the bank’s charter was reauthorized in December 2015. The bank is now authorized through September 30, 2019. However, until the U.S. Senate confirms members sufficient to reconstitute a quorum of the bank’s board of directors, the bank will not be able to approve any transaction totaling more than $10 million. As a result, we may fund additional commitments and/or enter into new financing arrangements with customers.
In the event we require additional funding to support strategic business opportunities, our commercial aircraft financing commitments, unfavorable resolution of litigation or other loss contingencies, or other business requirements, we expect to meet increased funding requirements by issuing commercial paper or term debt. We believe our ability to access external capital resources should be sufficient to satisfy existing short-term and long-term commitments and plans, and also to provide adequate financial flexibility to take advantage of potential strategic business opportunities should they arise within the next year. However, there can be no assurance of the cost or availability of future borrowings, if any, under our commercial paper program, in the debt markets or our credit facilities.
At March 31,September 30, 2016,, we were in compliance with the covenants for our debt and credit facilities. The most restrictive covenants include a limitation on mortgage debt and sale and leaseback transactions as a percentage of consolidated net tangible assets (as defined in the credit agreements), and a limitation on consolidated debt as a percentage of total capital (as defined). When considering debt covenants, we continue to have substantial borrowing capacity.
Off-Balance Sheet Arrangements
We are a party to certain off-balance sheet arrangements including certain guarantees. For discussion of these arrangements, see Note 9 to our Condensed 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 1516 to our Condensed Consolidated Financial Statements.
Environmental Remediation We are involved with various environmental remediation activities and have recorded a liability of $578576 million at March 31,September 30, 2016. For additional information, see Note 8 to our Condensed Consolidated Financial Statements.
Income Taxes As of March 31,September 30, 2016, we have $1,677$1,378 million of unrecognized tax benefits for uncertain tax positions. For further discussion of income taxes, see Note 3 to our Condensed Consolidated Financial Statements.

Non-GAAP Measures
Core Operating Earnings, Core Operating Margin and Core Earnings Per Share
Our unaudited condensed consolidated interim financial statements are prepared in accordance with Generally Accepted Accounting Principles in the United States of America (GAAP) which we supplement with certain non-GAAP financial information. These non-GAAP measures should not be considered in isolation or as a substitute for the related GAAP measures, and other companies may define such measures differently. We encourage investors to review our financial statements and publicly-filed reports in their entirety and not to rely on any single financial measure. Core operating earnings, core operating margin and core earnings per share exclude the impact of certain pension and other postretirement benefit expenses that are not allocated to business segments. Pension costs, comprising service and prior service costs computed in accordance with GAAP are allocated to Commercial Airplanes. Pension costs allocated to BDS segments -are computed in accordance with U.S. Government Cost Accounting Standards (CAS), which employ different actuarial assumptions and accounting conventions than GAAP. CAS costs are allocable to government contracts. Other postretirement benefit costs are allocated to all business segments based on CAS, which is generally based on benefits paid. The unallocated pension costs recognized in earnings was a benefit of $129 million and $50 million for the nine and three months ended September 30, 2016 compared with an expense of $293 million and $84 million for the same periods in 2015. The 2016 benefit reflects the difference between the higher segment allocation compared to the U.S. GAAP net periodic pension costs recognized in earnings in the current period. The 2015 unallocated expense reflects the amortization of pension costs capitalized as inventory in prior years. For further discussion of pension and other postretirement costs see Note 16tothe Management’s Discussion and Analysis on page 33 of this Form 10-Q and on page 46 of our Condensed Consolidated Financial Statements.2015 Annual Report on Form 10-K. Management uses core operating earnings, core operating margin and core earnings per share for purposes of evaluating and forecasting underlying business performance. Management believes these core earnings measures provide investors additional insights into operational performance as unallocated pension and other postretirement benefit cost, primarily represent costs driven by market factors and costs not allocable to U.S. government contracts.

Reconciliation of GAAP Measures to Non-GAAP Measures
The table below reconciles the non-GAAP financial measures of core operating earnings, core operating margin and core earnings per share with the most directly comparable GAAP financial measures of earnings from operations, operating margins and diluted earnings per share.

Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012 and Section 13(r) of the Securities Exchange Act of 1934, as amended (the “Act”), require disclosure of certain activities, transactions or dealings relating to Iran that occurred during the period covered by this report. Disclosure is required even if the activities, transactions or dealings were conducted in compliance with applicable law. During the first quarter of 2016, we provided updates to aircraft maintenance manuals to Iran Air Tours. We generated approximately $139 thousand in gross revenues and $16 thousand in net profits during the first quarter from these activities. These transfers were authorized by a license from the U.S. Office of Foreign Assets Control (“OFAC”). Boeing applied for the OFAC license consistent with guidance from the U.S. Government in connection with ongoing negotiations between the “P5+1” nations and Iran related to, among other things, the safety of Iran’s civil aviation industry. We may engage in additional activities pursuant to this license.
