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 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 plans 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 nine months ended 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 $656 and $384 and diluted earnings per share by $0.95 and $0.38 . For the three months ended 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 $210 and diluted earnings per share by $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:

The following table includes the number of shares that may be dilutive potential common shares in the future. These shares were not included in the computation of diluted earnings per share because the effect was either antidilutive or the performance condition was not met.

Note 3 – Income Taxes

Our effective income tax rates were 5.8% and (3.4)% for the nine and three months ended September 30, 2016 and 31.5% for the same periods in the prior year. The 2016 effective tax rates are lower than the prior year 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 at the end of 2015.

The total amount of unrecognized tax benefits decreased from $1,617 as of December 31, 2015 to $1,378 as of September 30, 2016 primarily due to the tax basis adjustment and settlement of the 2011-2012 federal tax audit, as discussed above.

Federal income tax audits have been settled for all years prior to 2013. The Internal Revenue Service (IRS) will begin the 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.

Note 4 – Inventories

Inventories consisted of the following:

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. The inventory balance was $120 (net of advances of $253 and $310 ) at September 30, 2016 and December 31, 2015 . See indemnifications to ULA in Note 9 .

Included in inventories are capitalized precontract costs of $650 and $732 primarily related to KC-46A Tanker and C-17 at September 30, 2016 and December 31, 2015 .

Commercial Aircraft Programs

At September 30, 2016 and December 31, 2015 , commercial aircraft programs inventory included the following amounts related to the 787 program: $33,423 and $34,656 of work in process (including deferred production costs of $27,523 and $28,510 ), $2,345 and $2,551 of supplier advances, and $3,691 and $3,890 of unamortized tooling and other non-recurring costs. At September 30, 2016 , $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 $8,693 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 a ccordingly, 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 September 30, 2016 and December 31, 2015 , commercial aircraft programs inventory included the following amounts related to the 747 program: $0 and $942 of deferred production costs, net of reach-forward losses, and $298 and $377 of unamortized tooling costs. At September 30, 2016 , $99 of unamortized tooling costs are expected to be recovered from units included in the program accounting quantity that have firm orders and $199 is expected to be recovered from units included in the program accounting quantity that represent expected future orders. At 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 $3,257 and $3,166 at September 30, 2016 and December 31, 2015 .

Used aircraft in inventories at Commercial Airplanes totaled $224 and $267 at September 30, 2016 and December 31, 2015 .

Note 5 – Customer Financing

Customer financing primarily relates to the Boeing Capital ( BCC ) segment and consisted of the following:

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 September 30, 2016 and December 31, 2015 , we individually evaluated for impairment customer financing receivables of $61 and $86 . At September 30, 2016 and December 31, 2015 , $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:

At September 30, 2016 , our allowance related to receivables with ratings of B, BB and BBB. We applied default rates that averaged 13% , 9% and 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 could 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.

The majority of customer financing carrying values are concentrated in the following aircraft models:

Note 6 – Investments

Our investments, which are recorded in Short-term and other investments or Investments, consisted of the following:

Note 7 – Other Assets

Sea Launch

At 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 May 12, 2016, the court issued a judgment in favor of Boeing relating to the bank guarantee payment and the 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. On May 16, 2016, the appellate court in Sweden dismissed the Swedish proceedings at our request.

We continue to pursue collection efforts in connection with the court 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 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.

Note 8 – Commitments and Contingencies

Environmental

The following table summarizes environmental remediation activity during the nine months ended September 30, 2016 and 2015 .

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 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 .

Product Warranties

The following table summarizes product warranty activity recorded during the nine months ended September 30, 2016 and 2015 .

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 September 30, 2016 have expiration dates from 2016 through 2026 . At September 30, 2016 , and December 31, 2015 total contractual trade-in commitments were $1,385 and $1,585 . As of 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 $170 and $240 and the fair value of the related trade-in aircraft was $170 and $240 .

Financing Commitments

Financing commitments, which include commitments to provide financing related to aircraft on order, under option for deliveries or proposed as part of sales campaigns, totaled $17,425 and $16,283 as of September 30, 2016 and December 31, 2015 . The estimated earliest potential funding dates for these commitments as of September 30, 2016 are as follows:

As of September 30, 2016 , $15,266 of these financing commitments related to customers we believe have less than investment-grade credit. 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 $4,368 and $4,968 as of 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 September 30, 2016 , ULA's total remaining obligation to Boeing under the inventory supply agreement was $120 . See Note 4 .

F/A-18

At September 30, 2016 , our backlog included 28 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 May 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 White House approved the proposed sale of up to 40 F/A-18 aircraft to Kuwait subject to the 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.

On September 29, 2016 a continuing resolution was enacted to fund the 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.

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 2016, we have recorded additional reach-forward losses of $816 on the KC-46A Tanker 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 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. 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. In August 2016, the USAF authorized LRIP lots for 7 and 12 aircraft valued at $2.8 billion . At September 30, 2016 , we had approximately $298 of capitalized precontract costs and $690 of potential termination liabilities to suppliers associated with aircraft we expect USAF to authorize in the 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

Lower-than-expected demand for large commercial passenger and freighter aircraft and slower-than-expected growth of global freight traffic have continued to drive market uncertainties, pricing pressures and fewer orders than anticipated. 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 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 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. We reduced the rate from 1.0 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 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 and/or market, production and other risks cannot be mitigated, we could record additional losses that may be 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 record 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 $1,278 of the $1,360 of inventory that was contributed by us and has yet to consume $82 . Under the inventory supply agreement, we have recorded revenues and cost of sales of $1,436 through 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. In 2009, ULA filed a complaint before the Armed Services Board of Contract Appeals (ASBCA) for a contract adjustment for the price of two of these missions, followed in 2011 by a subsequent notice of appeal with respect to a third mission. The USAF did not exercise an option for a fourth mission prior to the expiration of the contract. During the second quarter of 2016, the ASBCA ruled that ULA is entitled to additional contract pricing for each of the three missions and remanded to the parties to negotiate appropriate pricing. However, if the USAF appeals the ASBCA'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 four years.
