Financial and Other Business Information

See page 54 for the Summary of Business Segment Data and Note 22 to our Consolidated Financial Statements for financial information, including revenues and earnings from operations, for each of our business segments.

Intellectual Property

We own numerous patents and have licenses for the use of patents owned by others, which relate to our products and their manufacture. In addition to owning a large portfolio of intellectual property, we also license intellectual property to and from third parties. For example, the U.S. government has licenses in our patents that are developed in performance of government contracts, and it may use or authorize others to use the inventions covered by such patents for government purposes. Unpatented research, development and engineering skills, as well as certain trademarks, trade secrets, and other intellectual property rights, also make an important contribution to our business. While our intellectual property rights in the aggregate are important to the operation of each of our businesses, we do not believe that our business would be materially affected by the expiration of any particular intellectual property right or termination of any particular intellectual property patent license agreement.

Non-U.S. Revenues

See Note 22 to our Consolidated Financial Statements for information regarding non-U.S. revenues.

Research and Development

Research and development expenditures involve experimentation, design, development and related test activities for defense systems, new and derivative jet aircraft including both commercial and military, advanced space and other company-sponsored product development. These are expensed as incurred including amounts allocable as reimbursable overhead costs on U.S. government contracts.

Our total research and development expense amounted to $3.9 billion, $4.1 billion and $6.5 billion in 2011, 2010 and 2009, respectively. Research and development expense in 2009 included $2.7 billion of production costs related to the first three flight test 787 aircraft that cannot be sold due to the inordinate amount of rework and unique and extensive modifications that would be made to the aircraft.

Research and development costs also include bid and proposal efforts related to government products and services, as well as costs incurred in excess of amounts estimated to be recoverable under cost-sharing research and development agreements. Bid and proposal costs were $332 million, $355 million and $343 million in 2011, 2010 and 2009, respectively.

Research and development highlights for each of the major business segments are discussed in more detail in Segment Results of Operations and Financial Condition on pages 23 – 38.

Employees

Total workforce level at December 31, 2011 was approximately 171,700.

3

As of December 31, 2011, our principal collective bargaining agreements were with the following unions:

Union	Percent of our Employees Represented	Status of the Agreements with the Union
The International Association of Machinists and Aerospace Workers (IAM)	20%	We have two major agreements; one expiring in January of 2015 and one in September of 2016.
The Society of Professional Engineering Employees in Aerospace (SPEEA)	13%	We have two major agreements; one expiring in October of 2012 and one in December of 2013.
The United Automobile, Aerospace and Agricultural Implement Workers of America (UAW)	2%	We have two major agreements; one expiring in October of 2014 and one in February of 2015.

Competition

The commercial jet aircraft market and the airline industry remain extremely competitive. We face aggressive international competitors who are intent on increasing their market share, such as Airbus, Embraer and Bombardier, and other entrants from Russia, China and Japan. We are focused on improving our processes and continuing cost reduction efforts. We intend to continue to compete with other airplane manufacturers by providing customers with greater value products, services, and support. We continue to leverage our extensive customer support services network which includes aviation support, spares, training, maintenance documents and technical advice for airlines throughout the world to provide a higher level of customer satisfaction and productivity.

BDS faces strong competition in all market segments, primarily from Lockheed Martin Corporation, Northrop Grumman Corporation, Raytheon Company and General Dynamics Corporation. Non-U.S. companies such as BAE Systems and European Aeronautic Defence and Space Company (EADS), the parent of Airbus, continue to build a strategic presence in the U.S. market by strengthening their North American operations and partnering with U.S. defense companies. In addition, certain of our competitors have occasionally formed teams with other competitors to address specific customer requirements. BDS expects the trend of strong competition to continue into 2012 with many international firms attempting to increase their U.S. presence.

Regulatory Matters

Our businesses are heavily regulated in most of our markets. We deal with numerous U.S. government agencies and entities, including but not limited to all of the branches of the U.S. military, NASA, the Federal Aviation Administration (FAA) and the Department of Homeland Security. Similar government authorities exist in our international markets.

Government Contracts. The U.S. government, and other governments, may terminate any of our government contracts at their convenience, as well as for default, based on our failure to meet specified performance measurements. If any of our U.S. government contracts were to be terminated for convenience, we generally would be entitled to receive payment for work completed and allowable termination or cancellation costs. If any of our government contracts were to be terminated for default, generally the U.S. government would pay only for the work that has been accepted and can require us

4

to pay the difference between the original contract price and the cost to re-procure the contract items, net of the work accepted from the original contract. The U.S. government can also hold us liable for damages resulting from the default.

Commercial Aircraft. In the United States, our commercial aircraft products are required to comply with FAA regulations governing production and quality systems, airworthiness and installation approvals, repair procedures and continuing operational safety. Internationally, similar requirements exist for airworthiness, installation and operational approvals. These requirements are generally administered by the national aviation authorities of each country and, in the case of Europe, coordinated by the European Joint Aviation Authorities.

Environmental. We are subject to various federal, state, local and non-U.S. laws and regulations relating to environmental protection, including the discharge, treatment, storage, disposal and remediation of hazardous substances and wastes. We continually assess our compliance status and management of environmental matters to ensure our operations are in substantial compliance with all applicable environmental laws and regulations. Operating and maintenance costs associated with environmental compliance and management of sites are a normal, recurring part of our operations. These costs often are allowable costs under our contracts with the U.S. government. It is reasonably possible that continued environmental compliance could have a material impact on our results of operations, financial condition or cash flows if more stringent clean-up standards are imposed, additional contamination is discovered and/or clean-up costs are higher than estimated.

A Potentially Responsible Party (PRP) has joint and several liability under existing U.S. environmental laws. Where we have been designated a PRP by the Environmental Protection Agency or a state environmental agency, we are potentially liable to the government or third parties for the full cost of remediating contamination at our facilities or former facilities or at third-party sites. If we were required to fully fund the remediation of a site, the statutory framework would allow us to pursue rights to contribution from other PRPs. For additional information relating to environmental contingencies, see Note 12 to our Consolidated Financial Statements.

International. Our international sales are subject to U.S. and non-U.S. governmental regulations and procurement policies and practices, including regulations relating to import-export control, investment, exchange controls and repatriation of earnings. International sales are also subject to varying currency, political and economic risks.

Raw Materials, Parts, and Subassemblies

We are highly dependent on the availability of essential materials, parts and subassemblies from our suppliers and subcontractors. The most important raw materials required for our aerospace products are aluminum (sheet, plate, forgings and extrusions), titanium (sheet, plate, forgings and extrusions) and composites (including carbon and boron). Although alternative sources generally exist for these raw materials, qualification of the sources could take one year or more. Many major components and product equipment items are procured or subcontracted on a sole-source basis with a number of companies.

Suppliers

We are dependent upon the ability of a large number of suppliers and subcontractors to meet performance specifications, quality standards and delivery schedules at our anticipated costs. While we maintain an extensive qualification and performance surveillance system to control risk associated with such reliance on third parties, failure of suppliers or subcontractors to meet commitments could

5

adversely affect production schedules and program/contract profitability, thereby jeopardizing our ability to fulfill commitments to our customers. We are also dependent on the availability of energy sources, such as electricity, at affordable prices.

Seasonality

No material portion of our business is considered to be seasonal.

Our Commercial Airplanes business depends heavily on commercial airlines, and is subject to unique risks.

Market conditions have a significant impact on demand for our commercial aircraft. The commercial aircraft market is predominantly driven by long-term trends in airline passenger and cargo traffic. The principal factors underlying long-term traffic growth are sustained economic growth and political stability both in developed and emerging markets. Demand for our commercial aircraft is further influenced by airline profitability, availability of aircraft financing (including the industry’s ability to withstand the European sovereign debt crisis and other market developments), world trade policies, government-to-government relations, technological changes, price and other competitive factors, terrorism, epidemics and environmental regulations. Traditionally, the airline industry has been cyclical and very competitive and has experienced significant profit swings and constant challenges to be more cost competitive. Significant deterioration of the global economic environment or the financial health of the airline industry generally or of one or more of our major customers could result in fewer new orders for aircraft or could cause customers to seek to postpone or cancel contractual orders and/or payments to us, which could result in lower revenues, profitability and cash flows and a reduction in our contractual backlog. In addition, because our commercial aircraft backlog consists of aircraft scheduled for delivery over a period of several years, any of these industry or customer impacts could unexpectedly affect deliveries over a long period.

We enter into firm fixed-price aircraft sales contracts with indexed price escalation clauses which could subject us to losses if we have cost overruns or if increases in our costs exceed the applicable escalation rate. Commercial aircraft sales contracts are often entered into years before the aircraft are delivered. In order to account for economic fluctuations between the contract date and delivery date, aircraft pricing generally consists of a fixed amount as modified by an indexed price escalation formula. Our revenue estimates are based on current expectations with respect to these escalation formulas, but the actual escalation amounts are outside of our control. Escalation factors can fluctuate significantly from period to period. Changes in escalation amounts can significantly impact revenues and operating margins in our Commercial Airplanes business.

We derive a significant portion of our revenues from a limited number of commercial airlines. We can make no assurance that any customer will exercise purchase options, fulfill existing purchase commitments or purchase additional products or services from us after our contract with the customer ends. In addition, fleet decisions, airline consolidations or financial challenges involving any of our major commercial airline customers could significantly reduce our revenues and limit our opportunity to generate profits from those customers.

Our Commercial Airplanes business depends on our ability to develop new aircraft, achieve planned production rate increases across multiple programs and maintain a healthy production system.

The design and production of airplanes is complex and requires exotic materials, highly skilled employees and extensive coordination and integration with suppliers. As a result, our ability to deliver aircraft on time, satisfy contractual performance requirements and achieve or maintain, as applicable, program profitability is subject to significant risks. In addition, we are continuing to increase production rates for the 737, 747, 777 and 787 programs. These risks are increased by our simultaneous development of derivative aircraft, such as the 787-9 and the 737 MAX, the completion of design changes identified during flight testing into already-manufactured 747 and 787 aircraft, and our recent incorporation of a second 787 final assembly line into our production system.

If assembly line ramp-up efforts at any of our commercial aircraft assembly facilities are delayed or if our suppliers cannot timely deliver components to us at the rates necessary to achieve our planned rate increases, we may be unable to meet delivery schedules and the financial performance of one or

7

more of our programs may suffer. Operational issues, including delays or defects in supplier components, the inability to efficiently and cost-effectively incorporate design changes into 787 and 747 production aircraft, and aircraft performance issues, could impact our ability to achieve our targeted production rates, and may result in aircraft delivery delays, higher production costs and/or lower program revenues. If we fail to deliver aircraft to our customers on time or meet contractual performance requirements, we could experience order cancellations or other significant financial exposures, or a reduction of the profitability of our Commercial Airplanes business.

Our BDS business could be adversely affected by changing acquisition priorities of the U.S. government, particularly the Department of Defense, including an increased emphasis on affordability.

The U.S. government participates in an increasingly wide variety of operations, including homeland defense, natural disasters, stabilization efforts, counterinsurgency and counterterrorism, that employ our products and services. The U.S. government, primarily operating through the U.S. DoD, continues to adjust its funding priorities in response to this changing threat environment. In addition, defense funding currently faces pressures due to the overall economic environment and competing budget priorities. Due to these pressures, the total U.S. DoD budget could decline. Any reduction in levels of U.S. DoD spending or cancellations or delays impacting existing contracts could have a significant impact on the operating results of our BDS business. We also expect that the U.S. DoD will continue to emphasize cost-cutting and other efficiency initiatives in its procurement processes. These initiatives will require us and our competitors to focus increasingly on long-term cost competitiveness and affordability when responding to proposals and/or pursuing development programs. If the priorities of the U.S. government change and/or we are unable to meet affordability targets, our BDS revenues and profitability could be negatively impacted.

We depend heavily on U.S. government contracts, which are subject to unique risks.

In 2011, 38% of our revenues were derived from U.S. government contracts. In addition to normal business risks, our contracts with the U.S. government are subject to unique risks, some of which are beyond our control.

The funding of U.S. government programs is subject to congressional appropriations. Many of the U.S. government programs in which we participate may last several years; however, initially these programs are normally funded yearly, with additional funds committed in later years as Congress makes additional appropriations. As a result, long-term government contracts and related orders are subject to modification, curtailment or termination, if appropriations for subsequent performance periods are not made, either due to changes in U.S. national security strategy and priorities or fiscal constraints. For example, the U.S. Army notified us of the termination for convenience of the BCTM System Development and Demonstration contract relating to Manned Ground Vehicles and associated systems and equipment. Similar further budgetary pressures could affect the funding for one or more of our existing programs. The termination or reduction of funding for U.S. government programs could result in a material adverse effect on our earnings, cash flow and financial position.

The U.S. government may modify, curtail or terminate our contracts. The U.S. government may modify, curtail or terminate its contracts and subcontracts with us, without prior notice and at its convenience upon payment for work done and commitments made at the time of termination. In addition, if the U.S. government terminates a contract as a result of a default by us, we could be liable for additional costs, including reimbursement or damages. Modification, curtailment or termination of one or more of our major programs or contracts could have a material adverse effect on our results of operations and financial condition.

8

Our contract costs are subject to audits by U.S. government agencies. U.S. government representatives may audit the costs we incur on our U.S. government contracts, including allocated indirect costs. Such audits could result in adjustments to our contract costs. Any costs found to be improperly allocated to a specific contract will not be reimbursed, and such costs already reimbursed must be refunded. We have recorded contract revenues based upon costs we expect to realize upon final audit. However, we do not know the outcome of any future audits and adjustments and we may be required to reduce our revenues or profits upon completion and final negotiation of audits. If any audit uncovers improper or illegal activities, we may be subject to civil and criminal penalties and administrative sanctions, including termination of contracts, forfeiture of profits, suspension of payments, fines and suspension or prohibition from doing business with the U.S. government.

Our business is subject to potential U.S. government inquiries and investigations. We are subject to certain U.S. government inquiries and investigations due to our participation in government contracts. Any such inquiry or investigation could potentially result in fines, financial penalties, or suspension or debarment from future business opportunities, which could have a material adverse effect on our results of operations and financial condition.

Our sales to the U.S. government are also subject to specific procurement regulations and other requirements. U.S government procurement requirements are customary in U.S. government contracts, and generally result in increased performance and compliance costs. These costs might increase in the future, reducing our margins, which could have a negative effect on our financial condition. For example, in late 2011 the U.S. DoD published new regulations with stringent requirements and criteria to increase Government oversight of six key business systems of all prime contractors: accounting, earned value management, purchasing, material management and accounting, government property management and cost estimating. These new requirements and criteria may increase our compliance costs, and failure to comply with these regulations could result in the withholding of payments and harm our reputation and ability to secure future U.S. government contracts. Beginning in 2014, we also will be required to allocate higher pension costs to U.S. government contracts due to new requirements scheduled to be effective in 2012. These requirements could have a negative effect on our financial condition if we are unable to recoup these costs.

We enter into fixed-price contracts which could subject us to losses if we have cost overruns.

Our BDS business generated approximately 60% of its 2011 revenues from fixed-price contracts. While firm fixed price contracts enable us to benefit from performance improvements, cost reductions and efficiencies, they also subject us to the risk of reduced margins or incurring losses if we are unable to achieve estimated costs and revenues. If our estimated costs exceed our estimated price, we recognize reach-forward losses which can significantly affect our reported results. The long term nature of many of our contracts makes the process of estimating costs and revenues on fixed-price contracts inherently risky. Fixed-price contracts often contain price incentives and penalties tied to performance which can be difficult to estimate and have significant impacts on margins. In addition, some of our contracts have specific provisions relating to cost, schedule and performance.

Fixed-price development contracts are generally subject to more uncertainty than fixed-price production contracts. Many of these development programs have highly complex designs. If we fail to meet the terms specified in those contracts, our sales price could be reduced. In addition, technical or quality issues that arise during development could lead to schedule delays and higher costs to complete, which could result in a material charge or otherwise adversely affect our financial condition. Examples of significant BDS fixed-price development contracts include AEW&C, the USAF KC-46A Tanker, India P-8I and commercial and military satellites.

9

We enter into cost-type contracts which also carry risks.

Our BDS business generated approximately 40% of its 2011 revenues from cost-type contracting arrangements. Some of these are development programs that have complex design and technical challenges. These cost-type programs typically have award or incentive fees that are subject to uncertainty and may be earned over extended periods. 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. Programs whose contracts are primarily cost-type include GMD, BCTM, P-8A Poseidon, Proprietary programs, JTRS, FAB-T and the EA-18G Growler Airborne Attack Electronic Aircraft.

We enter into contracts that include in-orbit incentive payments that subject us to risks.

Contracts in the commercial satellite industry and certain government satellite contracts include in-orbit incentive payments. These in-orbit payments may be paid over time after final satellite acceptance or paid in full prior to final satellite acceptance. In both cases, the in-orbit incentive payment is at risk if the satellite does not perform to specifications for up to 15 years after acceptance. The net present value of in-orbit incentive fees we ultimately expect to realize is recognized as revenue in the construction period. If the satellite fails to meet contractual performance criteria, customers will not be obligated to continue making in-orbit payments and/or we may be required to provide refunds to the customer and incur significant charges.

Our ability to deliver products and services that satisfy customer requirements is heavily dependent on the performance of our subcontractors and suppliers, as well as on the availability of raw materials and other components.

We rely on other companies including subcontractors and suppliers to provide and produce raw materials, integrated components and sub-assemblies, and production commodities and to perform some of the services that we provide to our customers. If one or more of our suppliers or subcontractors experiences delivery delays or other performance problems, we may be unable to meet commitments to our customers. In addition, if one or more of the raw materials on which we depend (such as aluminum, titanium or composites) becomes unavailable or is available only at very high prices, we may be unable to deliver one or more of our products in a timely fashion or at budgeted costs. In some instances, we depend upon a single source of supply. Any service disruption from one of these suppliers, either due to circumstances beyond the supplier’s control or as a result of performance problems or financial difficulties, could have a material adverse effect on our ability to meet commitments to our customers or increase our operating costs.

We use estimates in accounting for many contracts and programs. Changes in our estimates could adversely affect our future financial results.

Contract and program accounting require judgment relative to assessing risks, estimating revenues and costs and making assumptions for schedule and technical issues. Due to the size and nature of many of our contracts and programs, the estimation of total revenues and cost at completion is complicated and subject to many variables. Assumptions have to be made regarding the length of time to complete the contract or program because costs also include expected increases in wages and employee benefits, material prices and allocated fixed costs. Incentives or penalties related to performance on contracts are considered in estimating sales and profit rates, and are recorded when there is sufficient information for us to assess anticipated performance. Suppliers’ assertions are also assessed and considered in estimating costs and profit rates. Estimates of award fees are also used in sales and profit rates based on actual and anticipated awards.

With respect to each of our commercial aircraft programs, inventoriable production costs (including overhead), program tooling and other non-recurring costs and routine warranty costs are accumulated

10

and charged as cost of sales by program instead of by individual units or contracts. A program consists of the estimated number of units (accounting quantity) of a product to be produced in a continuing, long-term production effort for delivery under existing and anticipated contracts limited by the ability to make reasonably dependable estimates. To establish the relationship of sales to cost of sales, program accounting requires estimates of (a) the number of units to be produced and sold in a program, (b) the period over which the units can reasonably be expected to be produced and (c) the units’ expected sales prices, production costs, program tooling and other non-recurring costs, and routine warranty costs for the total program. Several factors determine accounting quantity, including firm orders, letters of intent from prospective customers and market studies. Changes to customer or model mix, production costs and rates, learning curve, escalation, costs of derivative aircraft, supplier performance, customer negotiations/settlements, supplier claims and/or certification issues can impact these estimates. Any such change in estimates relating to program accounting may adversely affect future financial performance.

Because of the significance of the judgments and estimation processes described above, it is likely that materially different sales and profit amounts could be recorded if we used different assumptions or if the underlying circumstances were to change. Changes in underlying assumptions, circumstances or estimates may adversely affect future period financial performance. For additional information on our accounting policies for recognizing sales and profits, see our discussion under “Management’s Discussion and Analysis – Critical Accounting Policies – Contract Accounting/Program Accounting” on pages 42 – 44 and Note 1 to our Consolidated Financial Statements on pages 55 – 56 of this Form 10-K.

Competition within our markets may reduce our future contracts and sales.

The markets in which we operate are highly competitive and one or more of our competitors may have more extensive or more specialized engineering, manufacturing and marketing capabilities than we do in some areas. In our Commercial Airplanes business, we anticipate increasing competition among non-U.S. aircraft manufacturers and service providers in one or more of our market segments. In our BDS business, we anticipate that the effects of defense industry consolidation and new priorities, including long-term cost competitiveness, of our U.S. DoD customer will intensify competition for many of our products and services. Furthermore, we are facing increased international competition and cross-border consolidation of competition. There can be no assurance that we will be able to compete successfully against our current or future competitors or that the competitive pressures we face will not result in reduced revenues and market share.

We derive a significant portion of our revenues from non-U.S. sales and are subject to the risks of doing business in other countries.

In 2011, non-U.S. customers accounted for approximately 50% of our revenues. We expect that non-U.S. sales will continue to account for a significant portion of our revenues for the foreseeable future. As a result, we are subject to risks of doing business internationally, including:

· changes in regulatory requirements;

· domestic and international government policies, including requirements to expend a portion of program funds locally and governmental industrial cooperation or participation requirements;

· fluctuations in international currency exchange rates;

· volatility in international political and economic environments and changes in non-U.S. national priorities and budgets, which can lead to delays or fluctuations in orders;

· the complexity and necessity of using non-U.S. representatives and consultants;

11

· the uncertainty of the ability of non-U.S. customers to finance purchases, including the availability of financing from the U.S. Export-Import Bank;

· uncertainties and restrictions concerning the availability of funding credit or guarantees;

· imposition of taxes, export controls, tariffs, embargoes and other trade restrictions;

· the difficulty of management and operation of an enterprise spread over many countries;

· compliance with a variety of international laws, as well as U.S. laws affecting the activities of U.S. companies abroad; and

· economic and geopolitical developments and conditions.

While the impact of these factors is difficult to predict, any one or more of these factors could adversely affect our operations in the future.

The outcome of litigation and of government inquiries and investigations involving our business is unpredictable and an adverse decision in any such matter could result in significant monetary payments and have a material effect on our financial position and results of operations.

We are involved in a number of litigation matters. These claims may divert financial and management resources that would otherwise be used to benefit our operations. No assurances can be given that the results of these matters will be favorable to us. An adverse resolution of any of these lawsuits could have a material impact on our financial position and results of operations. In addition, we are sometimes subject to government inquiries and investigations of our business due, among other things, to our business relationships with the U.S government, the heavily regulated nature of our industry, and in the case of environmental proceedings, our ownership of certain property. Any such inquiry or investigation could potentially result in an adverse ruling against us, which could result in significant monetary payments (including possible environmental remediation costs) and have a material impact on our financial position and operating results.

A significant portion of our and Boeing Capital Corporation’s customer financing portfolio is concentrated among certain customers based in the United States, and in certain types of Boeing aircraft, which exposes us to concentration risks.

A significant portion of our customer financing portfolio is concentrated among certain customers and in distinct geographic regions, particularly in the United States. Our portfolio is also concentrated by varying degrees across Boeing aircraft product types, most notably 717 aircraft. If one or more customers holding a significant portion of our portfolio assets experiences financial difficulties or otherwise defaults on or does not renew its leases with us at their expiration, and we are unable to redeploy the aircraft on reasonable terms, or if the types of aircraft that are concentrated in our portfolio suffer greater than expected declines in value, our earnings, cash flows and/or financial position could be materially adversely affected.

We may be unable to obtain debt to fund our operations and contractual commitments at competitive rates, on commercially reasonable terms or in sufficient amounts.

We depend, in part, upon the issuance of debt to fund our operations and contractual commitments. As of December 31, 2011, our airplane financing commitments totaled $15,866 million, as compared to $9,865 million as of December 31, 2010. If we require additional funding in order to fund outstanding financing commitments or meet other business requirements, our market liquidity may not be sufficient. A number of factors could cause us to incur increased borrowing costs and to have greater difficulty accessing public and private markets for debt. These factors include disruptions or declines in the

12

global capital markets and/or a decline in our financial performance or outlook or credit ratings. The occurrence of any or all of these events may adversely affect our ability to fund our operations and contractual or financing commitments.

We may not realize the anticipated benefits of mergers, acquisitions, joint ventures/strategic alliances or divestitures.

As part of our business strategy, we may merge with or acquire businesses and/or form joint ventures and strategic alliances. Whether we realize the anticipated benefits from these acquisitions and related activities depends, in part, upon our ability to integrate the operations of the acquired business, the performance of the underlying product and service portfolio, the performance of the management team and other personnel of the acquired operations. Accordingly, our financial results could be adversely affected from unanticipated performance issues, legacy liabilities, transaction-related charges, amortization of expenses related to intangibles, charges for impairment of long-term assets, credit guarantees, partner performance and indemnifications. Consolidations of joint ventures could also impact our reported results of operations or financial position. While we believe that we have established appropriate and adequate procedures and processes to mitigate these risks, there is no assurance that these transactions will be successful. We also may make strategic divestitures from time to time. These transactions may result in continued financial involvement in the divested businesses, such as through guarantees or other financial arrangements, following the transaction. Nonperformance by those divested businesses could affect our future financial results through additional payment obligations, higher costs or asset write-downs.

Our insurance coverage may be inadequate to cover all significant risk exposures.

We are exposed to liabilities that are unique to the products and services we provide. While we maintain insurance for certain risks and, in some circumstances, we may receive indemnification from the U.S. government, insurance cannot be obtained to protect against all risks and liabilities. It is therefore possible that the amount of our insurance coverage may not cover all claims or liabilities, and we may be forced to bear substantial costs. For example, liabilities arising from the use of certain of our products, such as aircraft technologies, missile systems, border security systems, anti-terrorism technologies, and/or air traffic management systems may not be insurable on commercially reasonable terms. While many of these products are shielded from liability within the U.S. under the SAFETY Act provisions of the 2002 Homeland Security Act, no such protection is available outside the U.S., potentially resulting in significant liabilities. The amount of insurance coverage we are able to maintain may be inadequate to cover these or other claims or liabilities.

Business disruptions could seriously affect our future sales and financial condition or increase our costs and expenses.

Our business may be impacted by disruptions including threats to physical security, information technology or cyber-attacks or failures, damaging weather or other acts of nature and pandemics or other public health crises. Any of these disruptions could affect our internal operations or our ability to deliver products and services to our customers. Any significant production delays, or any destruction, manipulation or improper use of our data, information systems or networks could impact our sales, increase our expenses and/or have an adverse affect the reputation of Boeing and of our products and services.

13

Some of our and our suppliers’ workforces are represented by labor unions, which may lead to work stoppages.

Approximately 63,000 employees, which constitute 37% of our total workforce, are union represented as of December 31, 2011. We experienced a work stoppage in 2008 when a labor strike halted commercial aircraft and certain BMA program production and we may experience additional work stoppages in the future, which could adversely affect our business. We cannot predict how stable our relationships, currently with 12 U.S. labor organizations and 7 non-U.S. labor organizations, will be or whether we will be able to meet the unions’ requirements without impacting our financial condition. The unions may also limit our flexibility in dealing with our workforce. Union actions at suppliers can also affect us. Work stoppages and instability in our union relationships could delay the production and/or development of our products, which could strain relationships with customers and cause a loss of revenues which would adversely affect our operations.

Significant changes in discount rates, actual investment return on pension assets and other factors could reduce our earnings, equity, and increase pension contributions in future periods.

The actuarial assumptions underlying the income or expense we record for our pension and other postretirement benefit plans reflect assumptions relating to financial market and other economic conditions, such as the discount rate, the expected long-term rate of return on plan assets and expected future medical inflation. Changes to these assumptions and differences between projected and actual performance can have a significant effect on our annual pension and other post retirement costs and/or result in a significant change to Shareholders’ equity. For U.S. government contracts, we must allocate pension costs to individual contracts based on U.S. Cost Accounting Standards which can also affect contract profitability. For a discussion regarding how our financial statements can be affected by pension and other postretirement plan accounting policies, see “Management’s Discussion and Analysis—Critical Accounting Policies—Postretirement Plans” on pages 45 – 46 of this Form 10-K. Although GAAP expense and pension or other postretirement contributions are not directly related, the key economic factors that affect GAAP expense would also likely affect the amount of cash or common stock we would contribute to our plans. Potential pension contributions include both mandatory amounts required under federal law Employee Retirement Income Security Act (ERISA) and discretionary contributions to improve the plans’ funded status.

Our operations expose us to the risk of material environmental liabilities.

We are subject to various federal, state, local and non-U.S. laws and regulations related to environmental protection, including the discharge, treatment, storage, disposal and remediation of hazardous substances and wastes. We could incur substantial costs, including cleanup costs, fines and civil or criminal sanctions, as well as third-party claims for property damage or personal injury, if we were to violate or become liable under environmental laws or regulations. In some cases, we may be subject to such costs due to environmental impacts attributable to our current or past manufacturing operations or the operations of companies we have acquired. In other cases, we may become subject to such costs due to an indemnification agreement between us and a third party relating to such environmental liabilities. In addition, new laws and regulations, more stringent enforcement of existing laws and regulations, the discovery of previously unknown contamination or the imposition of new remediation requirements could result in additional costs. For additional information relating to environmental contingencies, see Note 12 to our Consolidated Financial Statements.

Unauthorized access to our or our customers’ information and systems could negatively impact our business.

We face certain security threats, including threats to the confidentiality, availability and integrity of our data and systems. We maintain an extensive network of technical security controls, policy enforcement mechanisms and monitoring systems in order to address these threats. While these measures are

14

designed to prevent, detect and respond to unauthorized activity in our systems, certain types of attacks could result in significant financial losses and/or reputational harm. In addition, we manage information technology systems for certain customers. Many of these customers face similar security threats. If we cannot prevent the unauthorized access, release and/or corruption of our customers’ confidential, classified or personally identifiable information, our reputation could be damaged, and/or we could face financial losses.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Consolidated Results of Operations and Financial Condition

Overview

We are a global market leader in design, development, manufacture, sale and support of commercial jetliners, military aircraft, satellites, missile defense, human space flight and launch systems and services. We are one of the two major manufacturers of 100+ seat airplanes for the worldwide commercial airline industry and one of the largest defense contractors in the U.S. While our principal operations are in the U.S., we conduct operations in many countries and rely on an extensive network of international partners, key suppliers and subcontractors.

Our strategy is centered on successful execution in healthy core businesses – Commercial Airplanes and Boeing Defense, Space & Security (BDS) – supplemented and supported by Boeing Capital Corporation (BCC). Taken together, these core businesses have historically generated substantial earnings and cash flow that permit us to invest in new products and services. We focus on producing the products and providing the services that the market demands and we price our products and services to provide a fair return for our shareholders while continuing to find new ways to improve efficiency and quality. Commercial Airplanes is committed to being the leader in commercial aviation by offering airplanes and services that deliver superior design, efficiency and value to customers around the world. BDS integrates its resources in defense, intelligence, communications, security and space to deliver capability-driven solutions to its customers at reduced costs. Our strategy is to leverage our core businesses to capture key next-generation programs while expanding our presence in adjacent and international markets, underscored by an intense focus on growth and productivity. Our strategy also benefits as the cyclicality of commercial and defense markets often offset. BCC delivers value by supporting our business units and managing overall financing exposure.

Consolidated Results of Operations

Revenues

(Dollars in millions)

Years ended December 31,	2011			2010			2009
Commercial Airplanes	$	36,171		$	31,834		$	34,051
Boeing Defense, Space & Security		31,976			31,943			33,661
Boeing Capital Corporation		532			639			660
Other segment		138			138			165
Unallocated items and eliminations		(82	)		(248	)		(256	)
Total	$	68,735		$	64,306		$	68,281

Revenues in 2011 increased by $4,429 million or 7% compared with 2010. Commercial Airplanes revenues increased by $4,337 million due to higher new airplane deliveries, including the impact of entry into service of the 787-8 and 747-8 Freighter, favorable new airplane delivery mix and higher commercial aviation services revenues. BDS revenues increased by $33 million primarily due to higher revenues in the Boeing Military Aircraft (BMA) and Global Services & Support (GS&S) segments, partially offset by lower revenues in the Network & Space Systems (N&SS) segment.

Revenues in 2010 decreased by $3,975 million or 6% compared with 2009. Commercial Airplanes revenues decreased by $2,217 million due to lower 777 deliveries primarily resulting from a production rate change from 7 to 5 per month beginning in June 2010 and no deliveries on the 747 program due

19

to the transition from the 747-400 to the 747-8. These were partially offset by increases in commercial aviation services business. BDS revenues decreased by $1,718 million primarily due to lower revenues in the N&SS segment.

Commercial Airplanes earnings increased by $489 million, primarily due to higher revenues and a reduction in research and development costs, partially offset by increases in period costs associated with business growth. BDS earnings increased by $283 million compared with 2010 due to higher earnings in the BMA and GS&S segments, partially offset by lower earnings in the N&SS segment. Other segment earnings increased by $381 million primarily due to a $241 million reduction in the allowance for losses on receivables during 2011. Unallocated items and eliminations in 2011 reduced earnings by $253 million compared with 2010 primarily due to higher pension and postretirement costs.

Operating earnings in 2010 increased by $2,875 million compared with 2009. Commercial Airplanes earnings increased by $3,589 million, primarily due to $2,693 million of costs related to the first three 787 flight test aircraft included in research and development expense in 2009 and the 2009 reach-forward losses on the 747 program of $1,352 million. BDS earnings decreased by $423 million compared with 2009 due to lower margins in the BMA segment and lower revenues in the N&SS segment. Other segment earnings decreased by $176 million primarily due to $119 million in intercompany guarantees related to aircraft impairment charges and reduced aircraft collateral values.

The most significant items included in Unallocated items and eliminations are shown in the following table:

(Dollars in millions)

Years ended December 31,	2011			2010			2009
Share-based plans	$	(83	)	$	(136	)	$	(189	)
Deferred compensation		(61	)		(112	)		(158	)
Pension		(269	)		54			110
Postretirement		(248	)		(59	)		(93	)
Eliminations and other		(327	)		(482	)		(264	)
Total	$	(988	)	$	(735	)	$	(594	)

Share-based plans expense decreased by $53 million in both 2011 and 2010 primarily due to the expiration of the ShareValue trust at June 30, 2010.

Deferred compensation expense decreased by $51 million and $46 million in 2011 and 2010. The year over year changes in deferred compensation expense are primarily driven by changes in our stock price and broad stock market conditions.

20

Eliminations and other unallocated items expense decreased by $155 million in 2011 and increased by $218 million in 2010 primarily due to timing of intercompany expense allocations and elimination of profit on intercompany items. 2010 expense also includes a $55 million charitable contribution.

Unallocated pension and other postretirement expense represents the difference between costs recognized under Generally Accepted Accounting Principles in the United States of America (GAAP) in the consolidated financial statements and federal cost accounting standards required to be utilized by our business segments for U.S. government contracting purposes. We recorded net periodic benefit cost related to pensions and other postretirement benefits of $3,127 million, $1,864 million and $1,816 million in 2011, 2010, and 2009, respectively. The increase in net periodic benefit costs related to pensions and other postretirement benefits is primarily due to higher amortization of actuarial losses and higher service costs driven by lower discount rates. Not all net periodic benefit cost is recognized in earnings in the period incurred because it is allocated to production as product costs and a portion remains in inventory at the end of the reporting period. A portion of pension and other postretirement expense is recorded in the business segments and the remainder is included in unallocated pension and other postretirement expense. The unallocated expense in 2011 includes $161 million of additional expense recorded during the third quarter due to an adjustment primarily related to prior years’ accumulated postretirement benefit obligations. See the discussion of the postretirement liabilities in Note 15 to our Consolidated Financial Statements. Earnings from operations included the following amounts allocated to business segments and Other unallocated items and eliminations.

Net earnings from continuing operations	$	4,011		$	3,311		$	1,335

Other income decreased by $5 million in 2011 due to lower interest rates. The increase of $78 million in 2010 was driven by investment income on higher cash and investment balances. Interest and debt expense decreased by $18 million in 2011 due to the replacement of debt at lower interest rates. The increase of $177 million in 2010 was due to debt issued in 2009.

Our effective income tax rate was 25.6%, 26.5% and 22.9% for the years ended December 31, 2011, 2010 and 2009, respectively. Our effective tax rate was lower in 2011 than in 2010 primarily due to an income tax charge of $150 million recorded during the first quarter of 2010 as a result of the Patient Protection and Affordable Care Act, as modified by the Health Care and Education Reconciliation Act of 2010. During 2011, our effective tax rate was reduced by 7.4% due to a tax benefit of $397 million

21

recorded as a result of settling the 2004-2006 federal audit. We do not expect to settle any outstanding federal audits in 2012. Our effective tax rate was higher in 2010 than 2009, primarily because pre-tax book income in 2010 was higher than in 2009 and because of the income tax charge of $150 million recorded during the first quarter of 2010. This was partially offset by a tax benefit of $371 million recorded during the fourth quarter of 2010 as a result of settling the 1998-2003 federal audit. For additional discussion related to Income Taxes, see Note 5 to our Consolidated Financial Statements.

Backlog

Our backlog at December 31 was as follows:

(Dollars in millions)	2011		2010		2009
Contractual Backlog:
Commercial Airplanes	$	293,303	$	255,591	$	250,476
Boeing Defense, Space & Security:
Boeing Military Aircraft		24,085		25,094		26,354
Network & Space Systems		9,056		9,586		7,746
Global Services & Support		13,213		13,684		11,924
Total Boeing Defense, Space & Security		46,354		48,364		46,024
Total contractual backlog	$	339,657	$	303,955	$	296,500
Unobligated backlog	$	15,775	$	16,871	$	19,058

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 increase in contractual backlog during 2011 and 2010 was due to commercial airplane orders in excess of deliveries and changes in projected revenue escalation for undelivered commercial airplanes.

Unobligated backlog includes U.S. and non-U.S. government definitive contracts for which funding has not been authorized. The decrease in unobligated backlog during 2011 is due to decreases at BDS of $3,135 million compared with 2010 primarily due to funding of existing multi-year contracts and termination for convenience by the U.S. Army of the Brigade Combat Team Modernization (BCTM) program, partially offset by the U.S. Air Force (USAF) contract for the KC-46A Tanker and the Missile Defense Agency Development and Sustainment Contract. The decrease in unobligated backlog during 2010 is due to decreases at BDS of $1,993 million compared with 2009 primarily due to funding of existing multi-year contracts including the V-22, BCTM and Chinook programs, partially offset by multi-year procurement contract awards on the F/A-18 and International Space Station programs.

Additional Considerations

KC-46A Tanker On February 24, 2011, we were awarded a contract from the USAF to design, develop, manufacture and deliver 4 next generation aerial refueling tankers. The KC-46A Tanker will be a derivative of our 767 commercial aircraft. This contract is a fixed-price incentive firm contract valued at $4.9 billion and involves highly complex designs. Changes to our estimated cost to perform the work could result in a material charge. This contract contains production options. If all options under the contract are exercised, we expect to deliver 179 aircraft for a total expected contract value of approximately $30 billion. For segment reporting purposes, backlog, revenues and costs are recorded in the Commercial Airplanes and BMA segments.

Business Environment and Trends

Airline Industry Environment Political turmoil in the Middle East, the March 2011 natural disasters in Japan, the European sovereign debt crisis, deficit reduction challenges in the United States and high fuel prices continue to impact the global economy and airline traffic and costs. In the face of these challenges, passenger traffic has generally been more resilient than air cargo traffic. Air cargo traffic began contracting in May, and 2011 full year estimates indicate no growth over 2010. In contrast, 2011 passenger traffic year-over-year growth is expected to average around 6%, above the long-term average of 5%. However, there continues to be significant performance variation between regions and airline business models, with emerging markets and low cost carriers leading in the passenger markets. Despite relatively resilient passenger traffic, net profits for the global airline industry were impacted in 2011 by high oil prices, which were approximately 40% higher, on average, than 2010 prices. Net profits for the global airline industry are expected to be modest this year, totaling $7 billion in 2011, reduced from $16 billion in 2010.

Airlines continue to focus on boosting revenue through alliances and partnerships and ancillary fees and services, while also cutting costs and renewing fleets to leverage more fuel efficient airplanes in a high-fuel-price environment. These airline strategies helped the airlines weather the global uncertainty in 2011. Current baseline forecasts for the economy and traffic suggest the outlook is for continued net profitability for the global airline industry in 2012, although expectations are that 2012 profits will be substantially lower than current estimates for 2011. Demand for commercial aircraft is also influenced by the availability of aircraft financing including export financing and other financing sources. Going into 2012 the European sovereign debt crisis remains a significant risk to the global economy and the airline industry.

The long-term outlook for the industry remains positive due to the fundamental drivers of air travel growth: economic growth and the increasing propensity to travel due to increased trade, globalization, and improved airline services driven by liberalization of air traffic rights between countries. Our 20-year forecast is for a long-term average growth rate of 5% - 6% per year for passenger and cargo traffic, based on a projected average annual worldwide real economic growth rate of 3%. Based on long-term global economic growth projections, and factoring in increased utilization of the worldwide airplane fleet and requirements to replace older airplanes, we project a $4.0 trillion market for 33,500 new airplanes over the next 20 years.

The industry remains vulnerable to near-term exogenous developments including fuel price spikes, credit market shocks, terrorism, natural disasters, conflicts, and increased global environmental regulations.

Industry Competitiveness The commercial jet airplane market and the airline industry remain extremely competitive. Market liberalization in Europe and Asia has enabled low-cost airlines to continue gaining market share. These airlines have increased the downward pressure on airfares. This results in continued cost pressures for all airlines and price pressure on our products. Major productivity gains are essential to ensure a favorable market position at acceptable profit margins.

Continued access to global markets remains vital to our ability to fully realize our sales potential and long-term investment returns. Approximately 15% of Commercial Airplanes’ contractual backlog, in dollar terms, is with U.S. airlines.

We face aggressive international competitors who are intent on increasing their market share. They offer competitive products and have access to most of the same customers and suppliers. Airbus has

23

historically invested heavily to create a family of products to compete with ours. Regional jet makers Embraer and Bombardier, coming from the less than 100-seat commercial jet market, continue to develop larger and more capable airplanes. Additionally, other competitors from Russia, China and Japan are likely to enter the 70 to 190 seat airplane market over the next few years. Many of these competitors have historically enjoyed access to government-provided financial support, including “launch aid,” which greatly reduces the commercial risks associated with airplane development activities and enables airplanes to be brought to market more quickly than otherwise possible. This market environment has resulted in intense pressures on pricing and other competitive factors, and we expect these pressures to continue or intensify in the coming years.

Worldwide, airplane sales are generally conducted in U.S. dollars. Fluctuating exchange rates affect the profit potential of our major competitors, all of whom have significant costs in other currencies. Changes in value of the U.S. dollar relative to their local currencies impact competitors’ revenues and profits. Competitors routinely respond to a relatively weaker U.S. dollar by aggressively reducing costs and increasing productivity, thereby improving their longer-term competitive posture. Airbus has announced such initiatives targeting overhead cost savings, a reduction in its development cycle and a significant increase in overall productivity through 2012. If the U.S. dollar strengthens, Airbus can use the improved efficiency to fund product development, gain market share through pricing and/or improve earnings.

We are focused on improving our processes and continuing cost-reduction efforts. We continue to leverage our extensive customer support services network which includes aviation support, spares, training, maintenance documents and technical advice for airlines throughout the world. This enables us to provide a high level of customer satisfaction and productivity. These efforts enhance our ability to pursue pricing strategies that enable us to price competitively.

Other		(23	)		(53	)
Total	$	4,337		$	(2,217	)

24

Revenues for 2011 increased by $4,337 million or 13.6% compared with 2010 due to higher new airplane deliveries, including the impact of entry into service of the 787-8 and 747-8 Freighter, favorable commercial airplane delivery model mix and higher commercial aviation services revenues. The increase in revenues from commercial aviation services was primarily due to increased sales of spares.

Revenues for 2010 decreased by $2,217 million or 6.5% compared with 2009. The decrease in new airplane revenues primarily reflects lower 777 deliveries resulting from a production rate change from 7 to 5 per month beginning in June 2010 and no deliveries on the 747 program due to the transition from the 747-400 to the 747-8 derivative. The increase in revenues from commercial aviation services business was primarily due to increased sales of spares.

Commercial airplanes deliveries as of December 31 were as follows:

	737			747		767		777		787		Total

⁽¹⁾  Includes intercompany deliveries of 7 737 airplanes in 2011, 5 737 airplanes in both 2010 and 2009.

Earnings From Operations

Earnings from operations for 2011 increased by $489 million compared with 2010. This increase reflects earnings of $376 million from higher revenues on new airplane deliveries, $180 million of higher earnings due to commercial aviation services volume and margins and $261 million of lower research and development expense, partially offset by increases of $328 million reflecting higher fleet support costs and other costs associated with business growth.

Earnings from operations for 2010 increased by $3,589 million compared with 2009. The increase was primarily due to the 2009 reclassification from inventory to research and development expense of costs related to the first three 787 flight test airplanes, and the 2009 reach-forward losses on the 747 program. Costs of $2,693 million included in research and development expense in 2009 for the first three flight test 787 airplanes were a result of our determination that these airplanes could not be sold. The reach-forward loss on the 747 program of $1,352 million during 2009 was primarily due to increased production costs, reductions in projected delivery price increases associated with escalation and the difficult market conditions affecting the 747-8. The remaining net decrease in earnings for 2010 was primarily attributable to increased research and development expense of $285 million and lower new airplane deliveries.

Backlog Firm backlog represents orders for products and services where no contingencies remain before Boeing and the customer are required to perform. Backlog does not include prospective orders where customer controlled contingencies remain, such as the customers receiving approval from their Board of Directors, shareholders or government and completing financing arrangements. All such contingencies must be satisfied or have expired prior to recording a new firm order even if satisfying such conditions is highly certain. Firm orders exclude options. A number of our customers may have

25

contractual remedies that may be implicated by program delays. We continue to address customer claims and requests for other contractual relief as they arise. However, once orders are included in firm backlog, orders remain in backlog until canceled or fulfilled, although the value of orders is adjusted as changes to price and schedule are agreed to with customers.

The increase in contractual backlog during 2011 and 2010 was due to orders in excess of deliveries and changes in projected revenue escalation, partially reduced by cancellations of orders. The increase in unobligated backlog in 2011 represents Commercial Airplanes’ share of the USAF contract for the KC-46A Tanker.

Accounting Quantity The accounting quantity is our estimate of the quantity of airplanes that will be produced for delivery under existing and anticipated contracts. The determination of the accounting quantity is limited by the ability to make reasonably dependable estimates of the revenue and cost of existing and anticipated contracts. It is a key determinant of the gross margins we recognize on sales of individual airplanes throughout a program’s life. Estimation of each program’s accounting quantity takes into account several factors that are indicative of the demand for that program, including firm orders, letters of intent from prospective customers and market studies. We review our program accounting quantities quarterly.

The accounting quantity for each program may include units that have been delivered, undelivered units under contract, and units anticipated to be under contract in the reasonable future (anticipated orders). In developing total program estimates, all of these items within the accounting quantity must be considered.

The table below provides details of the accounting quantities and firm orders by program as of December 31. Cumulative firm orders represent the cumulative number of commercial jet airplane deliveries plus undelivered firm orders.

* The initial accounting quantity for the 787 program was established in the third quarter of 2011.

737 Program The accounting quantity for the 737 program increased by 1,200 units in 2011 due to the program’s normal progress of obtaining additional orders and delivering airplanes. During 2010, we announced plans to increase monthly production from 31.5 to 35 airplanes per month beginning in 2012 and a further increase to 38 airplanes per month beginning in 2013. On June 15, 2011, to address continued demand for delivery positions, we announced plans to increase production of the 737 to 42 airplanes per month beginning in 2014. On August 30, 2011, we announced the launch of the 737 MAX, the new engine variant of the 737. First delivery of the 737 MAX is expected in 2017.

26

747 Program The accounting quantity for the 747 program increased by 25 units in 2011. The 747-8 Freighter was certified during the third quarter and first delivery occurred in October 2011. First flight of the 747-8 Intercontinental passenger derivative occurred in March 2011 and type certification was achieved in the fourth quarter of 2011. During 2011, expected first delivery of the 747-8 Intercontinental was moved from the fourth quarter of 2011 to the first quarter of 2012 due to a delay in flight testing and the time required to incorporate all flight test driven engineering and design changes. We remain focused on incorporating these and other changes identified during flight testing into completed airplanes, achieving a planned production rate increase from 1.5 to 2 airplanes per month in mid-2012, reducing out-of-sequence work and improving supply chain efficiency. We are also continuing to monitor cargo market conditions. If risks associated with these areas cannot be mitigated, the program could be impacted by customer claims, lower orders, supplier assertions and/or the recognition of an additional reach-forward loss. We continue to implement mitigation plans and cost-reduction efforts to improve program profitability and address program risks.

767 Program The accounting quantity for the 767 program increased by 36 units in 2011 due to the program’s normal progress of obtaining additional orders and delivering airplanes.

777 Program The accounting quantity for the 777 program increased by 200 units in 2011 due to the program’s normal progress of obtaining additional orders and delivering airplanes. The 777 program’s first delivery at 7 airplanes per month from 5 per month occurred in June 2011. A further increase to 8.3 airplanes per month is planned for the first quarter of 2013.

787 Program We completed initial type certification flight testing activities and received design and production certifications for the 787-8 during the third quarter of 2011. We delivered the first 787-8 airplane in September 2011 and delivered two additional aircraft in the fourth quarter of 2011. We also completed the critical design review for the 787-9 derivative in 2011. In October 2011 we announced that the expected date of first delivery of the 787-9 had moved to early 2014 from late 2013.

We continued to produce aircraft during flight testing and established a separate facility to incorporate engineering and other design changes identified during flight testing on already completed aircraft. We expect that aircraft completed in our Everett facility through mid-year 2012 will also require change incorporation. However, we expect that these later airplanes will require significantly less change incorporation than airplanes completed prior to 2012. We remain focused on achieving planned increases in 787 production rates while continuing to satisfy customer mission and performance requirements. We also continue to monitor and address challenges associated with aircraft assembly, including management of our extended global supply chain, incorporation of design changes into aircraft in various stages of assembly, completion and integration of traveled work as well as weight and systems integration. During 2011 we increased the production rate to 2.5 per month at our Everett final assembly line and started up the North Charleston final assembly line. We currently expect to increase the production rate of 787 aircraft to 10 aircraft per month in final assembly by the end of 2013 with first deliveries occurring at that rate in early 2014. Our efforts to achieve planned production rate targets include improving the production system, coordinating rate increases with suppliers, increasing production rates in both Everett and North Charleston, and establishing transitional surge capacity at Everett. In addition, we continue to work with our customers and suppliers to assess the specific impacts of prior 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 these airplanes were included in research and development expense. We believe that the other three 787 flight test aircraft are commercially saleable and we continue to include costs related to those airplanes in program inventory at December 31, 2011. If we determine that one or more of the other aircraft cannot be sold, we may incur additional charges.

27

During the third quarter of 2011, we established an initial accounting quantity of 1,100 units, representing approximately 10 years of production at planned production rates. The cumulative impacts of production challenges, change incorporation, schedule delays and customer and supplier impacts have created significant pressure on program profitability. As a result, we have recorded low margins on our 2011 deliveries. Future challenges, including not meeting one or more planned production rate increases going forward, or introducing the 787-9 derivative as scheduled, could result in additional customer claims and/or supplier assertions as well as result in 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.

Fleet Support We provide the operators of our commercial airplanes with assistance and services to facilitate efficient and safe airplane operation. Collectively known as fleet support services, these activities and services begin prior to airplane delivery and continue throughout the operational life of the airplane. They include flight and maintenance training, field service support costs, engineering services, information services and systems and technical data and documents. The costs for fleet support are expensed as incurred and have been historically less than 1.5% of total consolidated costs of products and services. These costs are expected to continue to increase due to the 787 and 747-8 entry into service.

Research and Development The following chart summarizes the time horizon between go-ahead and initial delivery for major Commercial Airplanes derivatives and programs.

Our Research and development expense decreased by $260 million in 2011. This was primarily due to certification of the 747-8 Freighter and 787-8.

Our Research and development expense decreased by $2,408 million in 2010. This was primarily due to the reclassification to research and development expense of $2,693 million of production costs related to the three 787 flight test airplanes in 2009, partially offset by a $285 million increase of other research and development expense.

Additional Considerations

The 787 and 747-8 programs highlight the risks inherent in new airplane programs and new derivative airplanes, including, for example, development of the 787-9. In the third quarter of 2011 we launched a variant of the 737 that will feature new more fuel efficient engines – the 737 MAX. Costs related to development of new programs and derivative airplanes are expensed as incurred. Costs to produce new airplanes are included in inventory and accounted for using program accounting. Airplane programs have risk for reach-forward losses if our estimated production costs exceed our estimated program revenues for the accounting quantity. Generally commercial airplanes are sold on a firm fixed-price basis with an indexed price escalation clause and are often sold several years before scheduled delivery. Each customer purchase agreement contains an escalation clause to account for the effects of economic fluctuations over the period of time from airplane sale to airplane delivery. A price escalation formula based on pre-defined factors is used to determine the final price of the airplane at the time of customer delivery. While firm fixed-price contracts allow us to benefit from cost savings, they also expose us to the risk of cost overruns. Many new airplanes and derivatives have highly

28

complex designs, utilize exotic materials and require extensive coordination and integration with supplier partners. As technical or quality issues arise, such as issues experienced on the 787 and 747-8 programs, we may experience schedule delays and higher costs to complete new programs and derivative airplanes. Additionally, price escalation factors may also impact margins by reducing the estimated price of airplanes delivered in the future. There are other factors that could also result in lower margins or a material charge if a program has or is determined to have reach-forward losses. These include: changes to the program accounting quantity, customer and model mix, production costs and rates, capital expenditures and other costs associated with increasing or adding new production capacity, learning curve, anticipated cost reductions, flight test and certification schedules, costs, schedule and demand for derivative airplanes and status of customer claims, supplier assertions and other contractual negotiations. While we believe the cost and revenue 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, order cancellations or other financially significant exposure.

Business Environment and Trends

U.S. Defense Environment Overview In August 2011, the Budget Control Act (the Act) reduced the DoD top line budget by approximately $490 billion over 10 years starting in fiscal year (FY) 2013. In addition, barring Congressional action, further budget cuts (or sequestration) as outlined in the Act will be implemented in FY13. Sequestration would lead to additional reductions of approximately $500 billion from the Pentagon’s top line budget over the next decade, resulting in aggregate reductions of about $1 trillion over 10 years. The U.S. DoD has taken the position that such reductions would generate significant operational risks and require the termination of certain procurement programs. Overseas Contingency Operations funding for Iraq and Afghanistan is also expected to decrease due to the reduction of U.S. forces in those countries.

In January 2012, the DoD announced its Defense Strategic Guidance (DSG) partly in response to these budgetary challenges. In response to the proposed “across the board” budget cuts the DSG proposed that the DoD prioritize the Asia Pacific and Middle East regions, shrink ground forces, maintain nuclear deterrence, and reduce Cold War assets. The DSG also emphasizes the increasing importance of Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance (C4ISR); Cyber; Space; Special Operations; and Unmanned Systems in implementing the DoD’s strategic imperatives. Specific program allocations commensurate with this new guidance are expected to be announced in February 2012 as part of the President’s FY13 budget request. While the DSG’s proposals do incorporate some of the proposed funding reductions, they do not address the full impact that would be associated with sequestration pursuant to the Act.

The budgetary pressures described above are expected to impact our other U.S. customers, including NASA, and the Intelligence community. To meet the needs of the DoD and other U.S. government customers in this challenging environment, BDS offers a balanced portfolio of platforms, services, and solutions that meet operational and fiscal requirements. However, these budgetary pressures are expected to place significant downward pressure on our revenues and margins in 2012.

Target Market Environment Overview The DSG places strong emphasis on developing and acquiring specific capabilities for the U.S. Armed Forces. Capabilities expected to remain a focus of investment or increase per the DoD Strategic Guidance include: C4ISR; Cyber; Space; Special Operations; and Unmanned Systems. BDS has been anticipating this shift in DoD priorities and has aligned its strategy accordingly. As such, we have been making organic investments and pursuing targeted acquisitions to enhance our capabilities and better serve our customers and their emerging needs in these markets.

29

International Environment Overview The international market continues to be driven by rapidly evolving security challenges and the need for countries to modernize aging inventories. Western governments are pressured by new threats to security while at the same time dealing with constrained budgets. In Europe, the continuing financial crisis and the growing potential for a double dip recession are causing a contraction in the credit market and forcing governments to institute austerity measures that will negatively impact defense spending in the near term.

The strongest opportunities for 2012 growth of the BDS portfolio will be in the Middle East and Asia Pacific regions where the relative financial strength of key countries coupled with a broad spectrum of evolving threats will result in procurement of defense and security systems. Similar to the domestic environment, BDS offers proven capability, predictable price, and near-term availability that are well suited to the enduring requirements in the international marketplace.

BDS Realignment

Effective January 1, 2011, 2010 and 2009, certain programs were realigned among BDS segments. Business segment data for all periods presented have been adjusted to reflect the realignment.

Operating Results

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 and earnings, 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.

Revenues

BDS revenues increased by $33 million in 2011 compared with 2010, due to higher revenues in the BMA and the GS&S segments, partially offset by lower revenues in the N&SS segment. BDS revenues decreased by $1,718 million in 2010 compared with 2009, due to lower revenues in all three segments, with the largest decrease in the N&SS segment.

Operating Earnings

BDS operating earnings in 2011 increased by $283 million compared with 2010 primarily due to higher earnings in the BMA and GS&S segments, partially offset by lower earnings in the N&SS segment. BDS operating earnings in 2010 decreased by $423 million compared with 2009 primarily due to lower margins in the BMA segment and lower revenues in the N&SS segment.

30

Backlog

Total backlog is comprised of contractual backlog, which represents work we are on contract to perform for which we have received funding, and unobligated backlog, which represents work we are on contract to perform for which funding has not yet been authorized and appropriated. BDS total backlog decreased by 8% in 2011, from $65,186 million to $60,041 million, primarily due to funding of existing multi-year contracts and termination for convenience by the U.S. Army of the BCTM program, partially offset by new orders. For further details on the changes between periods, refer to the discussions of the individual segments below.

Additional Considerations

Our 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 lower profit rates or program cancellation if milestones and technical progress are not accomplished. Examples of these programs include Family of Beyond Line-of-Sight Terminals, P-8A and Proprietary 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, 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. 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 our fixed-price development programs include Airborne Early Warning and Control (AEW&C), India P-8I, USAF KC-46A Tanker and commercial and military satellites.

Revenues

BMA revenues increased by 5% in 2011. The increase of $709 million in 2011 was primarily due to higher AEW&C, C-17 and KC-767 International Tanker revenues. AEW&C revenues increased by $780 million in 2011 due to delivery of the first two Peace Eye aircraft and higher Wedgetail milestone revenues. C-17 revenues increased by $273 million reflecting favorable mix, partially offset by fewer deliveries. International Tanker revenues increased by $235 million due to higher deliveries. In

31

addition, initial revenues on the USAF KC-46A Tanker were recognized in 2011. Lower volumes on the F-22, F/A-18 and Apache programs combined to reduce revenues by $613 million. Boeing production deliveries on the F-22 program ended in 2011. There were no new-build Apache deliveries in 2011, however, new-build deliveries are expected to resume in 2012.

BMA revenues decreased by less than 1% in 2010 compared with 2009. Lower revenues in 2010 on the C-17, Apache and T-45 programs were nearly offset by higher Chinook, F/A-18 and AEW&C revenues.

Deliveries of new-build production aircraft, excluding remanufactures and modifications, were as follows:

Years ended December 31,	2011		2010		2009

AH-64 Apache				13		23
T-45TS Goshawk						7
Total new-build production aircraft		115		115		121

Operating Earnings

BMA operating earnings increased by $276 million in 2011 primarily due to $236 million of higher earnings on the AEW&C program reflecting the initial Peace Eye deliveries and lower reach-forward loss provisions in 2011 on the AEW&C Wedgetail and Peace Eagle contracts. Lower reach-forward losses of $49 million on KC-767 International Tanker program and lower research and development also contributed to the earnings improvements. BMA operating earnings decreased by $277 million in 2010 primarily due to lower deliveries of C-17 aircraft and less favorable pricing and mix on the C-17 program.

Research and Development

The BMA segment continues to focus research and development resources to leverage customer knowledge, technical expertise and system integration of manned and unmanned systems that provide innovative solutions to meet the warfighter’s enduring needs. Research and development expense decreased in 2011 primarily due to lower International Tanker development costs. Research and development activities utilize our capabilities in architectures, system-of-systems integration and weapon systems technologies to develop solutions which are designed to better prepare us to meet customers’ needs in U.S. and international growth areas such as: military-commercial derivatives, rotorcraft, global strike, missiles and unmanned airborne systems, and surveillance and engagement systems. The products of our research and development support both new manned and unmanned systems as well as enhanced versions of existing fielded products. Investments support vertical integration of our product line in areas such as autonomous operation of unmanned systems, advanced sensors and electronic warfare. These efforts focus on increasing mission effectiveness, interoperability, reliability and reducing the cost of ownership.

Backlog

BMA total backlog in 2011 decreased by 6% from 2010, primarily due to current year deliveries and sales on multi-year contracts awarded in prior years partially offset by BMA’s share of the USAF

32

contract awards for the KC-46A and low-rate initial production of the P-8A. Total backlog in 2010 decreased 6% from 2009, primarily due to deliveries and sales on multi-year contracts awarded in prior years partially offset by a multi-year contract award on the F/A-18 program.

Additional Considerations

AEW&C

The AEW&C development program, also known as Wedgetail in Australia, Peace Eagle in Turkey and Peace Eye in the Republic of Korea, consists of 737-700 aircraft outfitted with a variety of command and control and advanced radar systems, some of which have never been installed on an airplane before. A total of five Wedgetail aircraft have been delivered to Australia with initial customer acceptance. Four were delivered in 2010 and one in September 2011. The final Wedgetail aircraft is scheduled for delivery with initial customer acceptance in the first quarter of 2012. Final customer acceptance for all six Wedgetail aircraft is also scheduled to be completed during the first half of 2012. In January 2011, the Peace Eagle program began the formal test phase which is scheduled to conclude in the second half of 2012. The first Peace Eye aircraft was delivered to the Republic of Korea in September 2011 and the second in December 2011. During 2011, 2010 and 2009, we recorded charges increasing the reach-forward losses on the AEW&C programs in Australia and Turkey by $60 million, $174 million and $133 million, respectively. These are advanced and complex fixed-price development programs involving technical challenges at the individual subsystem level and in the overall integration of these subsystems into a reliable and effective operational capability. We believe that the cost and revenue estimates incorporated in the financial statements are appropriate; however, the technical complexity of the programs creates financial risk as additional completion costs may be necessary or scheduled delivery dates could be delayed, either of which could result in lower margins or additional material charges.

Revenues

N&SS revenues decreased 8% in 2011 and 13% in 2010. The decrease of $782 million in 2011 is primarily due to $577 million of lower revenues on the BCTM program which was terminated for convenience during 2011. Lower revenues on the Ground-based Midcourse Defense (GMD), SBInet and Joint Tactical Radio System programs reduced revenues by $150 million, $146 million and $93 million respectively, partially offset by $150 million of higher sales of Delta inventory to United Launch Alliance (ULA) and $250 million of higher commercial and civil satellite revenues. The decrease of $1,422 million in 2010 is primarily due to lower volume on the BCTM and GMD programs.

Commercial and civil satellites		1		3		3
Military satellites		3		1		3

Operating Earnings

N&SS earnings decreased by $21 million in 2011 and $128 million in 2010 primarily due to lower revenues and higher research and development costs. N&SS operating earnings include equity earnings of $194 million, $189 million and $164 million from the United Space Alliance joint venture and the ULA joint venture in 2011, 2010 and 2009, respectively.

Research and Development

The N&SS research and development funding remains focused on the development of C4ISR that support a network-enabled architecture approach for our customers. Research and development expense increased in 2011 primarily due to higher expense associated with C4ISR prototypes. We are investing in capabilities to enhance connectivity between existing and new air/ground and maritime platforms, to increase communications availability, utility and bandwidth through more robust space systems, and to leverage innovative networking and ISR concepts. Investments were also made to develop concepts and capabilities related to cyber and security products, as well as the development of next-generation space and intelligence systems. Along with increased funding to support these network-enabled capabilities, we also maintained our investment levels in missile defense, directed energy and advanced exploration systems.

Backlog

N&SS total backlog decreased 14% in 2011 compared with 2010 primarily due to termination for convenience by the U.S. Army of the BCTM program and revenues recognized on multi-year contracts awarded in prior years, partially offset by the contract award for the Missile Defense Agency Development and Sustainment Contract. Total backlog increased 6% in 2010 compared with 2009 primarily due to two commercial satellite contract awards, a multi-year contract award on the International Space Station program and GMD contract awards, partially offset by revenues recognized on the BCTM program.

Revenues

GS&S revenues increased $106 million in 2011, an increase of 1%, and decreased $230 million in 2010, a decrease of 3%, in each case compared with the prior year. The 2011 increase is primarily due to higher revenues on several Integrated Logistics (IL) programs and a Defense & Government services contract, partially offset by lower revenues from Maintenance, Modifications and Upgrades (MM&U) due to the conclusion in 2010 of our KC-10 support program. The 2010 decrease is primarily due to lower revenues on several MM&U programs partially offset by higher revenues on several IL programs.

Operating Earnings

GS&S operating earnings increased by 3% in 2011 primarily due to higher earnings on several IL programs, partially offset by lower earnings on MM&U programs. Operating earnings decreased 2% in 2010 primarily due to lower revenues.

Research and Development

GS&S focused on its investment strategies in the following core businesses: IL, MM&U, Training Systems & Services (TS&S), and Defense & Government Services. Our investments also fund investigation into synergies between existing markets through our Advanced Services organization. This research continues the development and implementation of innovative tools, processes and systems which will deliver affordable readiness solutions to our customers.

Backlog

GS&S total backlog decreased by 3% in 2011 compared with 2010 primarily due to revenues recognized on multi-year contracts awarded in prior years on several IL programs, partially offset by a TS&S contract award on the P-8A program. Total backlog increased by 12% in 2010 compared with 2009 primarily due to the award of the UK LogNEC contract. Backlog also increased due to increases in several IL and MM&U programs, partially offset by decreases in several TS&S programs.

Boeing Capital Corporation

Business Environment and Trends

BCC’s customer financing and investment portfolio at December 31, 2011 totaled $4,327 million. A substantial portion of BCC’s portfolio is concentrated among certain U.S. commercial airline customers. BCC’s portfolio is also concentrated by varying degrees across Boeing aircraft product types most notably out-of-production Boeing aircraft such as 717 aircraft.

35

BCC provided customer financing of $239 million and $72 million during 2011 and 2010. The European sovereign debt crisis poses a financing risk to airlines and may reduce overall levels of commercial aircraft financing. However, we expect the reduction in funding from European commercial banks to be largely offset by increased financing availability from other sources, such as capital markets, lessors, and banks from other regions of the world.

Aircraft values and lease rates are impacted by the number and type of aircraft that are currently out of service. Approximately 2,000 western-built commercial jet aircraft (9.4% of current world fleet) were parked at the end of 2011, including both in-production and out-of-production aircraft types. Of these parked aircraft, approximately 30% are not expected to return to service. At the end of 2010 and 2009, 10.5% and 11.6% of the western-built commercial jet aircraft were parked. Aircraft valuations could decline if significant numbers of additional aircraft, particularly types with relatively few operators, are placed out of service.

Earnings from operations	$	125		$	152		$	126
Operating margins		23	%		24	%		19	%

Revenues

BCC segment revenues consist principally of lease income from equipment under operating lease and interest from financing receivables and notes. BCC’s revenues decreased $107 million in 2011 compared with 2010 primarily due to lower operating lease income from a smaller portfolio of equipment under operating leases as a result of aircraft returns and lower lease rates on re-leased aircraft and lower interest income on notes receivable resulting from a lower weighted average notes receivable balance and a decrease in the weighted average annual effective interest rate during 2011. The decrease in revenues in 2010 compared with 2009 of $21 million was primarily due to lower operating lease income from a smaller portfolio of equipment under operating leases as a result of aircraft returns and lower lease rates on re-leased aircraft.

Earnings From Operations

BCC’s operating earnings are presented net of interest expense, provision for (recovery of) losses, asset impairment expense, depreciation on leased equipment and other operating expenses. Operating earnings decreased by $27 million in 2011 compared with 2010 primarily due to lower revenues and higher asset impairment expense partially offset by lower interest expense, lower depreciation expense and a reduction in the allowance for losses. The increase in operating earnings in 2010 compared with 2009 was primarily due to lower asset impairment expense and a reduction in the allowance for losses.

Financial Position

The following table presents selected financial data for BCC as of December 31:

(Dollars in millions)	2011			2010

Debt	$	3,400		$	3,446
Debt-to-equity ratio		6.2-to-1			5.0-to-1

36

BCC’s customer financing and investment portfolio at December 31, 2011 decreased from December 31, 2010 due to normal portfolio run-off and asset sales, partially offset by the origination of notes receivable and purchase of equipment under operating lease. At December 31, 2011 and 2010, BCC had $521 million and $583 million of assets that were held for sale or re-lease, of which $476 million and $28 million had either executed term sheets with deposits or firm contracts to be sold or placed on lease. Additionally, aircraft subject to leases with a carrying value of approximately $111 million are scheduled to be returned off lease during 2012. These aircraft are being remarketed or the leases are being extended and approximately $13 million of such aircraft had either executed term sheets with deposits or firm contracts as of December 31, 2011.

BCC enters into certain transactions with the Other segment in the form of guarantees and other subsidies that mitigate the effects of certain credit quality or asset impairment issues on the BCC segment.

Bankruptcies

On November 29, 2011, American Airlines, Inc. (American Airlines) filed for Chapter 11 bankruptcy protection. American Airlines retains certain rights by operating under Chapter 11 bankruptcy protection, including the right to reject executory contracts, such as aircraft leases. At December 31, 2011 American Airlines accounted for $653 million of our customer financing portfolio, including $362 million recorded by BCC. American Airlines has not rejected any of the leases related to our aircraft. We believe that our customer financing receivables from American Airlines are sufficiently collateralized such that we do not expect to incur losses related to those receivables as a result of the bankruptcy. We continue to monitor the American Airlines bankruptcy for potential impacts on our business.

Restructurings and Restructuring Requests

From time to time, certain customers have requested a restructuring of their transactions with BCC. As of December 31, 2011, BCC has not reached agreement on any restructuring requests that would have a material effect on our earnings, cash flows and/or financial position.

On May 2, 2011, Southwest Airlines Co. (Southwest) completed its acquisition of AirTran Holdings, Inc. AirTran Holdings’ successor entity (AirTran) and its subsidiaries represent approximately 26% of our gross customer financing portfolio carrying value, consisting principally of 717 aircraft. AirTran is the largest customer in terms of BCC’s segment revenue and customer financing portfolio carrying value. In the fourth quarter of 2011, we revised the contractual terms of our leases with AirTran in conjunction with receiving a full guarantee from Southwest of those lease payment obligations. Revenue and earnings are expected to be approximately $30 million lower in 2012 due to these lease revisions.

Operating Activities Net cash provided by operating activities increased by $1,071 million to $4,023 million during 2011 compared with 2010 primarily due to higher earnings and lower working capital growth as the continued growth in inventory was partially offset by increases in advances from customers and accounts payable. Our investment in gross inventories increased to $56,499 million at December 31, 2011, up from $46,738 million at December 31, 2010 while advances and progress billings increased to $39,755 million at December 31, 2011 compared with $34,744 million at December 31, 2010. The increase in inventory was driven by higher investments in commercial airplane program inventory, specifically 787 inventory, while higher advances and progress payments reflect increased production rates and commercial airplane orders. We expect inventory to grow at a lower rate in 2012 as additional deliveries offset the ramp up of commercial airplane production and as design changes are incorporated into completed 747 and 787 airplanes. Cash contributions to our pension plans totaled $531 million and $35 million in 2011 and 2010.

Investing Activities Cash provided by investing activities totaled $2,369 million during 2011 compared with $4,831 million used during 2010, primarily due to lower investments in time deposits during 2011. In 2011, capital expenditures totaled $1,713 million up from $1,125 million in 2010. Capital spending in 2011 is higher than 2010 due to the construction of a 787 final assembly factory and related site buildings in North Charleston, South Carolina, higher spending to support commercial airplane production rate increases and capital improvements. We expect capital expenditures to be higher in 2012 due to continued investment to ramp up commercial production rates. Expenditures on acquisitions totaled $42 million, down from $932 million in 2010 which included the acquisition of Argon ST, Inc. for $782 million.

Financing Activities Cash used by financing activities totaled $1,700 million during 2011 compared with $1,962 million used during 2010 as proceeds from new borrowings of $799 million in 2011 more than offset $314 million of higher repayments of distribution rights financing and $241 million of higher debt repayments.

In 2011, net proceeds from BCC borrowings amounted to $745 million and we repaid $930 million of debt, including repayments of $798 million of debt held at BCC. At December 31, 2011 and 2010, the

recorded balance of debt was $12,371 million and $12,421 million, of which $2,353 million and $948 million were classified as short-term. This includes $3,400 million and $3,446 million of debt recorded at BCC, of which $879 million and $801 million were classified as short-term.

In 2011 and 2010, we had 350,778 and 494,939 shares transferred to us from employees for tax withholding and did not repurchase any shares through our open market share repurchase program. During 2009, cash used in our open market share repurchase program totaled $50 million.

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 and BCC have commercial paper programs that continue to serve as significant potential sources of short-term liquidity. Throughout 2011 and at December 31, 2011, neither we nor BCC had any commercial paper borrowings outstanding. Currently, we have $4,600 million ($1,500 million exclusively available for BCC) of unused borrowing on revolving credit line agreements. We anticipate that these credit lines will primarily serve as backup liquidity to support possible commercial paper borrowings.

Financing commitments totaled $15,866 million and $9,865 million as of December 31, 2011 and December 31, 2010. 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 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 December 31, 2011 and 2010, our pension plans were $16,600 million and $9,854 million underfunded as measured under GAAP. On an ERISA basis our plans were approximately 99% funded at December 31, 2011 with minimal required contributions in 2012. We expect to make discretionary contributions to our plans of approximately $1,500 million in 2012. We may be required to make higher contributions to our pension plans in future years.

As of December 31, 2011, 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.

Contractual Obligations

The following table summarizes our known obligations to make future payments pursuant to certain contracts as of December 31, 2011, and the estimated timing thereof.

(Dollars in millions)	Total		Less than 1 year		1-3 years		3-5 years		After 5 years
Long-term debt (including current portion)	$	12,158	$	2,257	$	2,563	$	1,864	$	5,474
Interest on debt(1)		6,433		584		893		737		4,219
Pension and other postretirement cash requirements		27,778		612		4,503		8,827		13,836
Capital lease obligations		235		99		118		17		1
Operating lease obligations		1,311		202		333		180		596
Purchase obligations not recorded on the Consolidated Statements of Financial Position		106,235		36,589		37,591		21,749		10,306
Purchase obligations recorded on the Consolidated Statements of Financial Position		14,153		13,432		699		4		18
Total contractual obligations	$	168,303	$	53,775	$	46,700	$	33,378	$	34,450

⁽¹⁾ Includes interest on variable rate debt calculated based on interest rates at December 31, 2011. Variable rate debt was approximately 1% of our total debt at December 31, 2011.

Pension and Other Postretirement Benefits Pension cash requirements are based on an estimate of our minimum funding requirements, pursuant to ERISA regulations, although we may make additional discretionary contributions. Estimates of other postretirement benefits are based on both our estimated future benefit payments and the estimated contributions to plans that are funded through trusts.

Purchase Obligations Purchase obligations represent contractual agreements to purchase goods or services that are legally binding; specify a fixed, minimum or range of quantities; specify a fixed, minimum, variable, or indexed price provision; and specify approximate timing of the transaction. Purchase obligations include amounts recorded as well as amounts that are not recorded on the Consolidated Statements of Financial Position. Approximately 6% of the purchase obligations disclosed above are reimbursable to us pursuant to cost-type government contracts.

Purchase Obligations Not Recorded on the Consolidated Statements of Financial Position Production related purchase obligations not recorded on the Consolidated Statements of Financial Position include agreements for inventory procurement, tooling costs, electricity and natural gas contracts, property, plant and equipment, and other miscellaneous production related obligations. The most significant obligation relates to inventory procurement contracts. We have entered into certain significant inventory procurement contracts that specify determinable prices and quantities, and long-term delivery timeframes. In addition, we purchase raw materials on behalf of our suppliers. These agreements require suppliers and vendors to be prepared to build and deliver items in sufficient time to meet our production schedules. The need for such arrangements with suppliers and vendors arises from the extended production planning horizon for many of our products. A significant portion of these inventory commitments is supported by firm contracts and/or has historically resulted in settlement through reimbursement from customers for penalty payments to the supplier should the customer not take delivery. These amounts are also included in our forecasts of costs for program and contract accounting. Some inventory procurement contracts may include escalation adjustments. In these limited cases, we have included our best estimate of the effect of the escalation adjustment in the amounts disclosed in the table above.

40

Purchase Obligations Recorded on the Consolidated Statements of Financial Position Purchase obligations recorded on the Consolidated Statements of Financial Position primarily include accounts payable and certain other liabilities including accrued compensation.

Industrial Participation Agreements We have entered into various industrial participation agreements with certain customers outside of the U.S. to facilitate economic flow back and/or technology transfer to their businesses or government agencies as the result of their procurement of goods and/or services from us. These commitments may be satisfied by our placement of direct work or vendor orders for supplies, opportunities to bid on supply contracts, transfer of technology or other forms of assistance. However, in certain cases, our commitments may be satisfied through other parties (such as our vendors) who purchase supplies from our non-U.S. customers. We do not commit to industrial participation agreements unless a contract for sale of our products or services is signed. In certain cases, penalties could be imposed if we do not meet our industrial participation commitments. During 2011, we incurred no such penalties. As of December 31, 2011, we have outstanding industrial participation agreements totaling $11.1 billion that extend through 2024. Purchase order commitments associated with industrial participation agreements are included in purchase obligations in the table above. To be eligible for such a purchase order commitment from us, a foreign supplier must have sufficient capability to meet our requirements and must be competitive in cost, quality and schedule.

Income Tax Obligations As of December 31, 2011, our net asset for income taxes receivable, including uncertain tax positions, was $179 million. We are not able to reasonably estimate the timing of future cash flows related to uncertain tax positions. Our income tax matters are excluded from the table above. See Note 5 to our Consolidated Financial Statements.

Commercial Commitments

The following table summarizes our commercial commitments outstanding as of December 31, 2011.

(Dollars in millions)	Total Amounts Committed/Maximum Amount of Loss		Less than 1 year		1-3 years		4-5 years		After 5 years
Standby letters of credit and surety bonds	$	6,199	$	4,693	$	1,064	$	304	$	138
Commercial aircraft financing commitments		15,866		1,562		3,424		6,114		4,766
Total commercial commitments	$	22,065	$	6,255	$	4,488	$	6,418	$	4,904

Commercial aircraft financing commitments include commitments to provide financing related to aircraft on order, under option for deliveries or proposed as part of sales campaigns based on estimated earliest potential funding dates. Based on historical experience, we anticipate that we will not be required to fund a significant portion of our financing commitments. However, there can be no assurances that we will not be required to fund greater amounts than historically required. See Note 12 to our Consolidated Financial Statements.

Contingent Obligations

We have significant contingent obligations that arise in the ordinary course of business, which include the following:

Legal Various legal proceedings, claims and investigations are pending against us. Legal contingencies are discussed in Note 21 to our Consolidated Financial Statements, including our contesting the default termination of the A-12 aircraft, certain employment, labor and benefits litigation, litigation/arbitration involving Boeing Satellite Systems International, Inc. programs and civil securities litigation relating to disclosures concerning the 787 program.

41

Environmental Remediation We are involved with various environmental remediation activities and have recorded a liability of $758 million at December 31, 2011. For additional information, see Note 12 to our Consolidated Financial Statements.

Income Taxes We have recorded a liability of $939 million at December 31, 2011 for uncertain tax positions. For further discussion of these contingencies, see Note 5 to our Consolidated Financial Statements.

Off-Balance Sheet Arrangements

We are a party to certain off-balance sheet arrangements including certain guarantees. For discussion of these arrangements, see Note 13 to our Consolidated Financial Statements.

Critical Accounting Policies

Contract Accounting

We use contract accounting to determine revenue, cost of sales, and profit for almost all of our BDS business. Contract accounting involves a judgmental process of estimating the total sales and costs for each contract, which results in the development of estimated cost of sales percentages. For each contract, the amount reported as cost of sales is determined by applying the estimated cost of sales percentage to the amount of revenue recognized.

Due to the size, duration and nature of many of our contracts, the estimation of total sales and costs through completion is complicated and subject to many variables. Total contract sales estimates are based on negotiated contract prices and quantities, modified by our assumptions regarding contract options, change orders, incentive and award provisions associated with technical performance, and price adjustment clauses (such as inflation or index-based clauses). The majority of these contracts are with the U.S. government. Generally the price is based on estimated cost to produce the product or service plus profit. Federal acquisition regulations provide guidance on the types of cost that will be reimbursed in establishing contract price. Total contract cost estimates are largely based on negotiated or estimated purchase contract terms, historical performance trends, business base and other economic projections. Factors that influence these estimates include inflationary trends, technical and schedule risk, internal and subcontractor performance trends, business volume assumptions, asset utilization, and anticipated labor agreements.

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 as a charge to earnings. For the years ending December 31, 2011, 2010 and 2009 cumulative catch-up adjustments, including reach-forward losses, across all BDS contracts increased operating earnings by $229 million, $125 million and $29 million respectively. Significant adjustments recorded during the three years ended December 31, 2011 relate to reach-forward losses on the AEW&C and the KC-767 International Tanker programs.

Due to the significance of judgment in the estimation process described above, it is likely that materially different cost of sales amounts could be recorded if we used different assumptions or if the underlying circumstances were to change. Changes in underlying assumptions/estimates, supplier performance, or circumstances may adversely or positively affect financial performance in future periods. If the combined gross margin for all contracts in BDS for all of 2011 had been estimated to be higher or lower by 1%, it would have increased or decreased pre-tax income for the year by approximately $320 million. In addition, a number of our fixed price development contracts are in a reach-forward loss position. Changes to estimated losses are recorded immediately in earnings.

42

Program Accounting

Program accounting requires the demonstrated ability to reliably estimate the relationship of sales to costs for the defined program accounting quantity. A program consists of the estimated number of units (accounting quantity) of a product to be produced in a continuing, long-term production effort for delivery under existing and anticipated contracts. The determination of the accounting quantity is limited by the ability to make reasonably dependable estimates of the revenue and cost of existing and anticipated contracts. For each program, the amount reported as cost of sales is determined by applying the estimated cost of sales percentage for the total remaining program to the amount of sales recognized for airplanes delivered and accepted by the customer.

Factors that must be estimated include program accounting quantity, sales price, labor and employee benefit costs, material costs, procured part costs, major component costs, overhead costs, program tooling and other non-recurring costs, and routine warranty costs. Estimation of the accounting quantity for each program takes into account several factors that are indicative of the demand for the particular program, such as firm orders, letters of intent from prospective customers, and market studies. Total estimated program sales are determined by estimating the model mix and sales price for all unsold units within the accounting quantity, added together with the sales prices for all undelivered units under contract. The sales prices for all undelivered units within the accounting quantity include an escalation adjustment that is based on projected escalation rates, consistent with typical sales contract terms. Cost estimates are based largely on negotiated and anticipated contracts with suppliers, historical performance trends, and business base and other economic projections. Factors that influence these estimates include production rates, internal and subcontractor performance trends, customer and/or supplier claims or assertions, asset utilization, anticipated labor agreements, and inflationary trends.

To ensure reliability in our estimates, we employ a rigorous estimating process that is reviewed and updated on a quarterly basis. Changes in estimates are normally recognized on a prospective basis; when estimated costs to complete a program exceed estimated revenues from undelivered units in the accounting quantity, a loss provision is recorded in the current period for the estimated loss on all undelivered units in the accounting quantity.

The program method of accounting allocates tooling and other non-recurring and production costs over the accounting quantity for each program. Because of the higher unit production costs experienced at the beginning of a new program and substantial investment required for initial tooling and other non-recurring costs, new commercial aircraft programs, such as the 787 program, typically have lower margins than established programs.

Due to the significance of judgment in the estimation process described above, it is likely that materially different cost of sales amounts could be recorded if we used different assumptions, or if the underlying circumstances were to change. Changes in underlying assumptions/estimates, supplier performance, or other circumstances may adversely or positively affect financial performance in future periods. If combined cost of sales percentages for commercial airplane programs, excluding the 747 and 787 programs, for all of 2011 had been estimated to be higher or lower by 1%, it would have increased or decreased pre-tax income for the year by approximately $276 million.

The 747 program is in a reach-forward loss position having recorded a total of $2,037 million of reach-forward losses in 2009 and 2008. Absent changes in the estimated revenues or costs, subsequent deliveries are recorded at zero margin. Reductions to the estimated loss in subsequent periods are spread over all undelivered units in the accounting quantity, whereas increases to the estimated loss are recorded immediately. Any such increases could result in additional charges.

The 787 program has a low single digit profit margin. The cumulative impacts of the production challenges, schedule delays and customer and supplier impacts continue to place significant pressure

43

on revenues, costs and the profitability of the 787 program. The scale and duration of the 787 program is such that relatively minor changes in assumptions or variables could have a material effect on our reported results in any period if the program is determined to have a reach-forward loss.

Aircraft Valuation

Allowance for Losses on Customer Financing Receivables The allowance for losses on customer financing receivables (valuation provision) is used to provide for potential impairment of customer financing receivables in the Consolidated Statements of Financial Position. The balance represents an estimate of probable but unconfirmed losses in the customer financing receivables portfolio. The estimate is based on various qualitative and quantitative factors, including historical loss experience, collateral values, and results of individual credit and collectibility reviews. The adequacy of the allowance is assessed quarterly.

Three primary factors influencing the level of our allowance are customer credit ratings, collateral values and default rates. If each customer’s credit rating were upgraded or downgraded by one major rating category at December 31, 2011, the allowance would have decreased by $41 million or increased by $107 million. If the collateral values were 20% higher or lower at December 31, 2011, the allowance would have decreased by $24 million or increased by $21 million. If the cumulative default rates used for each rating category increased or decreased 1%, the allowance would have increased or decreased by $7 million.

Impairment Review for Assets Under Operating Leases and Held for Re-Lease We evaluate for impairment assets under operating lease or assets held for re-lease when events or changes in circumstances indicate that the expected undiscounted cash flow from the asset may be less than its carrying value. We use various assumptions when determining the expected undiscounted cash flow including the expected future lease rates, lease terms, residual value of the asset, periods in which the asset may be held in preparation for a follow-on lease, maintenance costs, remarketing costs and the remaining economic life of the asset.

When we determine that impairment is indicated for an asset, the amount of impairment expense recorded is the excess of the carrying value over the fair value of the asset.

Had future lease rates on assets evaluated for impairment been 10% lower, we estimate that we would have incurred additional impairment expense of $10 million for the year ended December 31, 2011.

Residual Values Equipment under operating leases and assets held for re-lease are carried at cost less accumulated depreciation and are depreciated to estimated residual value using the straight-line method over the period that we project we will hold the asset for lease. Estimates used in determining residual values significantly impact the amount and timing of depreciation expense for equipment under operating leases and assets held for re-lease. If the estimated residual values declined 20% at December 31, 2011, we estimate that we would have incurred additional impairment expense of $19 million for the year ended December 31, 2011, and a future cumulative pre-tax earnings reduction of approximately $106 million recognized over the remaining depreciable periods, of which approximately $11 million would be recognized in 2012.

Our investment in sales-type/finance leases includes future minimum lease payments receivable plus the estimated residual value of leased assets less unearned income. Declines in estimated residual value that are deemed other than temporary are recognized in the period in which the decline occurs. If the estimated residual values declined 20% at December 31, 2011, we estimate that we would have reduced pre-tax income by $48 million for the year ended December 31, 2011.

44

Goodwill and Indefinite-Lived Intangible Impairments

Goodwill and other acquired intangible assets with indefinite lives are not amortized but are annually tested for impairment, and when an event occurs or circumstances change such that it is reasonably possible that an impairment may exist. April 1 is our annual testing date. We test goodwill for impairment by first comparing the book value of net assets to the fair value of the related operations. If the fair value is determined to be less than book value, a second step is performed to compute the amount of the impairment. In this process, a fair value for goodwill is estimated, based in part on the fair value of the operations, and is compared to its carrying value. The shortfall of the fair value below carrying value represents the amount of goodwill impairment.

We estimate the fair values of the related operations using discounted cash flows. Forecasts of future cash flows are based on our best estimate of future sales and operating costs, based primarily on existing firm orders, expected future orders, contracts with suppliers, labor agreements, and general market conditions. Changes in these forecasts could significantly change the amount of impairment recorded, if any.

The cash flow forecasts are adjusted by an appropriate discount rate derived from our market capitalization plus a suitable control premium at the date of evaluation. Therefore, changes in the stock price may also affect the amount of impairment recorded, if any.

We completed our assessment of goodwill as of April 1, 2011 and determined that the estimated fair value of each reporting unit significantly exceeded its corresponding carrying value. Changes in our forecasts or decreases in the value of our common stock could cause book values of certain operations to exceed their fair values which may result in goodwill impairment charges in future periods. A 10% decrease in the estimated fair value of any of our operations would have no impact on the carrying value of goodwill.

As of December 31, 2011 and 2010, we had $497 million of indefinite-lived intangible assets related to the Jeppesen and Aviall brand and trade names acquired in business combinations. We test these intangibles for impairment by comparing their carrying value to current projections of discounted cash flows attributable to the brand and tradenames. Any excess carrying value over the amount of discounted cash flows represents the amount of the impairment. A 10% decrease in the discounted cash flows would reduce the carrying value of these indefinite-lived intangible assets by less than $1 million.

Postretirement Plans

The majority of our employees are covered by defined benefit pension plans. All nonunion and some union employees hired after December 31, 2008 are not covered by defined benefit plans. We also have other postretirement benefits consisting principally of healthcare coverage for eligible retirees and qualifying dependents. Accounting rules require an annual measurement of our projected obligations and plan assets. These measurements are based upon several assumptions, including the discount rate, the expected long-term rate of asset return, and medical trend rate (rate of growth for medical costs). Future changes in assumptions or differences between actual and expected outcomes can significantly affect our future annual expense, projected benefit obligations and Shareholders’ equity.

45

The following table shows the sensitivity of our pension and other postretirement benefit plan liabilities and net periodic cost to a 25 basis point change in the discount rate as of December 31, 2011.

(Dollars in millions)	Change in discount rate Increase 25 bps			Change in discount rate Decrease 25 bps
Pension plans
Projected benefit obligation	$	(2,108	)	$	2,684
Net periodic pension cost		(220	)		280
Other postretirement benefit plans
Accumulated postretirement benefit obligation		(173	)		203
Net periodic postretirement benefit cost		(13	)		15

Pension expense is also sensitive to changes in the expected long-term rate of asset return. A decrease or increase of 25 basis points in the expected long-term rate of asset return would have increased or decreased 2011 net periodic pension expense by $124 million. We expect 2012 net periodic pension cost to increase by approximately $700 million and the portion recognized in earnings for 2012 to increase by approximately $1.0 billion primarily due to a reduction in the discount rate from 5.3% at December 31, 2010 to 4.4% at December 31, 2011 and amortization of actuarial losses. Absent increases in interest rates, higher asset values and/or higher contributions, net periodic pension cost will increase further in future years.

The assumed medical trend rates have a significant effect on the following year’s expense, recorded liabilities and Shareholders’ equity. The following table shows the sensitivity of our other postretirement benefit plan liabilities and net periodic cost to a 100 basis point change as of December 31, 2011.

(Dollars in millions)	Change in medical trend rate Increase 100 bps		Change in medical trend rate Decrease 100 bps
Other postretirement benefit plans
Accumulated postretirement benefit obligation	$	642	$	(572	)
Net periodic postretirement benefit cost		127		(111	)

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

We have financial instruments that are subject to interest rate risk, principally fixed-rate debt obligations, and customer financing assets and liabilities. Additionally, BCC uses interest rate swaps with certain debt obligations to manage exposure to interest rate changes. Exposure to this risk is managed by generally matching the profile of BCC’s liabilities with that of BCC’s assets in relation to amount and terms such as expected maturities and fixed versus floating interest rates. As of December 31, 2011, the impact over the next 12 months of a 100 basis point immediate and sustained rise or fall in interest rates would be a $10 million increase or a $1 million decrease to BCC’s pre-tax earnings. For purposes of the foregoing sensitivity analysis, we assume that the level of our floating rate assets and debt (including the impact of derivatives) remain unchanged from year-end 2011 and that they are all subject to immediate re-pricing. Historically, we have not experienced material gains or losses on our investments or customer financing assets and liabilities due to interest rate changes.

Based on the portfolio of other Boeing fixed-rate debt, the unhedged exposure to interest rate risk is not material. The investors in our fixed-rate debt obligations do not generally have the right to demand we pay off these obligations prior to maturity. Therefore, exposure to interest rate risk is not believed to be material for our fixed-rate debt.

Foreign Currency Exchange Rate Risk

We are subject to foreign currency exchange rate risk relating to receipts from customers and payments to suppliers in foreign currencies. We use foreign currency forward and option contracts to hedge the price risk associated with firmly committed and forecasted foreign denominated payments and receipts related to our ongoing business. Foreign currency forward and option contracts are sensitive to changes in foreign currency exchange rates. At December 31, 2011, a 10% increase in the exchange rate in our portfolio of foreign currency contracts would have decreased our unrealized gains by $220 million and a 10% decrease in the exchange rate would have increased our unrealized gains by $248 million. Consistent with the use of these contracts to neutralize the effect of exchange rate fluctuations, such unrealized losses or gains would be offset by corresponding gains or losses, respectively, in the remeasurement of the underlying transactions being hedged. When taken together, these forward currency contracts and the offsetting underlying commitments do not create material market risk.

Notes to the Consolidated Financial Statements

Years ended December 31, 2011, 2010 and 2009

(Dollars in millions, except per share data)

Note 1 – Summary of Significant Accounting Policies

Principles of Consolidation and Basis of Presentation

The Consolidated 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”). These statements include the accounts of all majority-owned subsidiaries and variable interest entities that are required to be consolidated. All significant intercompany accounts and transactions have been eliminated. Certain amounts have been reclassified to conform to the current year presentation.

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 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 Consolidated Financial Statements.

Operating Cycle

For classification of certain current assets and liabilities, we use the duration of the related contract or program as our operating cycle, which is generally longer than one year and could exceed three years.

Revenue and Related Cost Recognition

Contract Accounting Contract accounting is used for development and production activities predominantly by Boeing Defense, Space & Security (BDS). The majority of business conducted by BDS is performed under contracts with the U.S. government and other customers that extend over several years. Contract accounting involves a judgmental process of estimating the total sales and costs for each contract resulting in the development of estimated cost of sales percentages. For each contract, the amount reported as cost of sales is determined by applying the estimated cost of sales percentage to the amount of revenue recognized.

Changes in estimated revenues, cost of sales and the related effect to 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. In 2011, 2010 and 2009 net favorable cumulative catch-up adjustments increased operating earnings by $229, $125 and $29 respectively and EPS by $0.23, $0.12 and $0.03 respectively. Significant adjustments recorded during the three years ended December 31, 2011 relate to reach-forward losses on the AEW&C and the KC-767 International Tanker programs.

We combine contracts for accounting purposes when they are negotiated as a package with an overall profit margin objective. These essentially represent an agreement to do a single project for a single customer, involve interrelated construction activities with substantial common costs, and are performed concurrently or sequentially. When a group of contracts is combined, revenue and profit are earned uniformly over the performance of the combined contracts. Similarly, we may segment a single contract or group of contracts when a clear economic decision has been made during contract negotiations that would produce different rates of profitability for each element or phase of the contract.

55

Sales related to fixed-price contracts are recognized as deliveries are made, except for certain fixed-price contracts that require substantial performance over an extended period before deliveries begin, for which sales are recorded based on the attainment of performance milestones. Sales related to contracts in which we are reimbursed for costs incurred plus an agreed upon profit are recorded as costs are incurred. The Federal Acquisition Regulations provide guidance on the types of cost that will be reimbursed in establishing contract price. Contracts may contain provisions to earn incentive and award fees if specified targets are achieved. Incentive and award fees that can be reasonably estimated and are probable are recorded over the performance period of the contract. Incentive and award fees that cannot be reasonably estimated are recorded when awarded.

Program Accounting Our Commercial Airplanes segment predominantly uses program accounting to account for cost of sales related to its programs. Program accounting is applicable to products manufactured for delivery under production-type contracts where profitability is realized over multiple contracts and years. Under program accounting, inventoriable production costs, program tooling and other non-recurring costs, and routine warranty costs are accumulated and charged to cost of sales by program instead of by individual units or contracts. A program consists of the estimated number of units (accounting quantity) of a product to be produced in a continuing, long-term production effort for delivery under existing and anticipated contracts. The determination of the accounting quantity is limited by the ability to make reasonably dependable estimates of the revenue and cost of existing and anticipated contracts. To establish the relationship of sales to cost of sales, program accounting requires estimates of (a) the number of units to be produced and sold in a program, (b) the period over which the units can reasonably be expected to be produced, and (c) the units’ expected sales prices, production costs, program tooling and other non-recurring costs, and routine warranty costs for the total program.

We recognize sales for commercial airplane deliveries as each unit is completed and accepted by the customer. Sales recognized represent the price negotiated with the customer, adjusted by an escalation formula as specified in the customer agreement. The amount reported as cost of sales is determined by applying the estimated cost of sales percentage for the total remaining program to the amount of sales recognized for airplanes delivered and accepted by the customer. Changes in estimated revenues, cost of sales and the related effects on program margins are recognized prospectively except in cases where the program is determined to have a reach-forward loss in which case the loss is recognized in the current period.

Concession Sharing Arrangements We account for sales concessions to our customers in consideration of their purchase of products and services as a reduction to revenue when the related products and services are delivered. The sales concessions incurred may be partially reimbursed by certain suppliers in accordance with concession sharing arrangements. We record these reimbursements, which are presumed to represent reductions in the price of the vendor’s products or services, as a reduction in Cost of products.

Spare Parts Revenue We recognize sales of spare parts upon delivery and the amount reported as cost of sales is recorded at average cost.

Service Revenue Service revenue is recognized when the service is performed with the exception of U.S. government service agreements, which are accounted for using contract accounting. Service activities primarily include: support agreements associated with military aircraft and helicopter contracts, ongoing maintenance of International Space Station and Space Shuttle, commercial Delta launches and technical and flight operation services for commercial aircraft. Service revenue and associated cost of sales from pay-in-advance subscription fees are deferred and recognized as services are rendered.

56

Financial Services Revenue We record financial services revenue associated with sales-type/finance leases, operating leases, and notes receivable.

Lease and financing revenue arrangements are included in Sales of services on the Consolidated Statements of Operations. For sales-type/finance leases, we record an asset at lease inception. This asset is recorded at the aggregate future minimum lease payments, estimated residual value of the leased equipment, and deferred incremental direct costs less unearned income. Income is recognized over the life of the lease to approximate a level rate of return on the net investment. Residual values, which are reviewed periodically, represent the estimated amount we expect to receive at lease termination from the disposition of the leased equipment. Actual residual values realized could differ from these estimates. Declines in estimated residual value that are deemed other-than-temporary are recognized as Cost of services in the period in which the declines occur.

For operating leases, revenue on leased aircraft and equipment is recorded on a straight-line basis over the term of the lease. Operating lease assets, included in Customer financing, are recorded at cost and depreciated over the period that we project we will hold the asset to an estimated residual value, using the straight-line method. We periodically review our estimates of residual value and recognize forecasted changes by prospectively adjusting depreciation expense.

For notes receivable, notes are recorded net of any unamortized discounts and deferred incremental direct costs. Interest income and amortization of any discounts are recorded ratably over the related term of the note.

Reinsurance Revenue Our wholly-owned insurance subsidiary, Astro Ltd., participates in a reinsurance pool for workers’ compensation. The member agreements and practices of the reinsurance pool minimize any participating members’ individual risk. Reinsurance revenues were $144, $139 and $122 during 2011, 2010 and 2009, respectively. Reinsurance costs related to premiums and claims paid to the reinsurance pool were $142, $123 and $118 during 2011, 2010 and 2009, respectively. Revenues and costs are presented net in Cost of services in the Consolidated Statements of Operations.

Fleet Support

We provide assistance and services to facilitate efficient and safe aircraft operation to the operators of all our commercial airplane models. Collectively known as fleet support services, these activities and services include flight and maintenance training, field service support, engineering services, and technical data and documents. Fleet support activity begins prior to aircraft delivery as the customer receives training, manuals, and technical consulting support. This activity continues throughout the aircraft’s operational life. Services provided after delivery include field service support, consulting on maintenance, repair, and operational issues brought forth by the customer or regulators, updating manuals and engineering data, and the issuance of service bulletins that impact the entire model’s fleet. Field service support involves our personnel located at customer facilities providing and coordinating fleet support activities and requests. The costs for fleet support are expensed as incurred as Cost of services.

Research and Development

Research and development includes costs incurred for experimentation, design, testing, and bid and proposal efforts related to government products and services which are expensed as incurred unless the costs are related to certain contractual arrangements with customers. Costs that are incurred pursuant to such contractual arrangements are recorded over the period that revenue is recognized, consistent with our contract accounting policy. We have certain research and development

57

arrangements that meet the requirement for best efforts research and development accounting. Accordingly, the amounts funded by the customer are recognized as an offset to our research and development expense rather than as contract revenues.

We have established cost sharing arrangements with some suppliers for the 787 program. Our cost sharing arrangements state that the supplier contributions are for reimbursements of costs we incur for experimentation, basic design, and testing activities during the 787 development. In each arrangement, we retain substantial rights to the 787 part or component covered by the arrangement. The amounts received from these cost sharing arrangements are recorded as a reduction to research and development expenses since we have no obligation to refund any amounts received per the arrangements regardless of the outcome of the development efforts. Specifically, under the terms of each agreement, payments received from suppliers for their share of the costs are typically based on milestones and are recognized as earned when we achieve the milestone events and no ongoing obligation on our part exists. In the event we receive a milestone payment prior to the completion of the milestone, the amount is classified in Accrued liabilities until earned.

Share-Based Compensation

We provide various forms of share-based compensation to our employees. For awards settled in shares, we measure compensation expense based on the grant-date fair value net of estimated forfeitures. For awards settled in cash, or that may be settled in cash, we measure compensation expense based on the fair value at each reporting date net of estimated forfeitures. The expense is recognized over the requisite service period, which is generally the vesting period of the award.

Income Taxes

Provisions for federal, state, and non-U.S. income taxes are calculated on reported Earnings before income taxes based on current tax law and also include, in the current period, the cumulative effect of any changes in tax rates from those used previously in determining deferred tax assets and liabilities. Such provisions differ from the amounts currently receivable or payable because certain items of income and expense are recognized in different time periods for financial reporting purposes than for income tax purposes. Significant judgment is required in determining income tax provisions and evaluating tax positions.

The accounting for uncertainty in income taxes requires a more-likely-than-not threshold for financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. We record a liability for the difference between the benefit recognized and measured for financial statement purposes and the tax position taken or expected to be taken on our tax return. To the extent that our assessment of such tax positions changes, the change in estimate is recorded in the period in which the determination is made. Tax-related interest and penalties are classified as a component of Income tax expense.

Postretirement Plans

The majority of our employees are covered by defined benefit pension plans. All nonunion and some union employees hired after December 31, 2008 are not covered by defined benefit plans. We also provide postretirement benefit plans other than pensions, consisting principally of health care coverage to eligible retirees and qualifying dependents. Benefits under the pension and other postretirement benefit plans are generally based on age at retirement and years of service and, for some pension plans, benefits are also based on the employee’s annual earnings. The net periodic cost of our pension and other postretirement plans is determined using the projected unit credit method and several actuarial assumptions, the most significant of which are the discount rate, the long-term rate of asset

58

return, and medical trend (rate of growth for medical costs). A portion of net periodic pension and other postretirement income or expense is not recognized in net earnings in the year incurred because it is allocated to production as product costs, and reflected in inventory at the end of a reporting period. Actuarial gains and losses, which occur when actual experience differs from actuarial assumptions, are reflected in Shareholders’ equity (net of taxes). If actuarial gains and losses exceed ten percent of the greater of plan assets or plan liabilities we amortize them over the average future service period of employees. The funded status of our pension and postretirement plans is reflected on the Consolidated Statements of Financial Position.

Postemployment Plans

We record a liability for postemployment benefits, such as severance or job training, when payment is probable, the amount is reasonably estimable, and the obligation relates to rights that have vested or accumulated.

Environmental Remediation

We are subject to federal and state requirements for protection of the environment, including those for discharge of hazardous materials and remediation of contaminated sites. We routinely assess, based on in-depth studies, expert analyses and legal reviews, our contingencies, obligations, and commitments for remediation of contaminated sites, including assessments of ranges and probabilities of recoveries from other responsible parties and/or insurance carriers. Our policy is to accrue and charge to current expense identified exposures related to environmental remediation sites when it is probable that a liability has been incurred and the amount can be reasonably estimated. The amount of the liability is based on our best estimate or the low end of a range of reasonably possible exposure for investigation, cleanup, and monitoring costs to be incurred. Estimated remediation costs are not discounted to present value as the timing of payments cannot be reasonably estimated. We may be able to recover a portion of the remediation costs from insurers or other third parties. Such recoveries are recorded when realization of the claim for recovery is deemed probable.

Cash and Cash Equivalents

Cash and cash equivalents consist of highly liquid instruments, such as commercial paper, time deposits, and other money market instruments, which have original maturities of three months or less. We aggregate our cash balances by bank where conditions for right of set-off are met, and reclassify any negative balances, consisting mainly of uncleared checks, to Accounts payable. Negative balances reclassified to Accounts payable were $132 and $209 at December 31, 2011 and 2010.

Inventories

Inventoried costs on commercial aircraft programs and long-term contracts include direct engineering, production and tooling and other non-recurring costs, and applicable overhead, which includes fringe benefits, production related indirect and plant management salaries and plant services, not in excess of estimated net realizable value. To the extent a material amount of such costs are related to an abnormal event or are fixed costs not appropriately attributable to our programs or contracts, they are expensed in the current period rather than inventoried. Inventoried costs include amounts relating to programs and contracts with long-term production cycles, a portion of which is not expected to be realized within one year. Included in inventory for federal government contracts is an allocation of allowable costs related to manufacturing process reengineering.

Commercial aircraft programs inventory includes deferred production costs. Deferred production costs represent actual costs incurred for production of early units that exceed the estimated average cost of

59

all units in the program accounting quantity. Higher production costs are experienced at the beginning of a new or derivative airplane program. Units produced early in a program require substantially more effort (labor and other resources) than units produced later in a program because of volume efficiencies and the effects of learning. We expect that these deferred costs will be fully recovered when all units included in the accounting quantity are delivered as the expected unit cost for later deliveries is below the estimated average cost of all units in the program.

The determination of net realizable value of long-term contract costs is based upon quarterly reviews that estimate costs to be incurred to complete all contract requirements. When actual contract costs and the estimate to complete exceed total estimated contract revenues, a loss provision is recorded. The determination of net realizable value of commercial aircraft program costs is based upon quarterly program reviews that estimate revenue and cost to be incurred to complete the program accounting quantity. When estimated costs to complete exceed estimated program revenues to go, a program loss provision is recorded in the current period for the estimated loss on all undelivered units in the accounting quantity.

Used aircraft purchased by the Commercial Airplanes segment and general stock materials are stated at cost not in excess of net realizable value. See ‘Aircraft Valuation’ within this Note for a discussion of our valuation of used aircraft. Spare parts inventory is stated at lower of average unit cost or market. We review our commercial spare parts and general stock materials quarterly to identify impaired inventory, including excess or obsolete inventory, based on historical sales trends, expected production usage, and the size and age of the aircraft fleet using the part. Impaired inventories are charged to Cost of products in the period the impairment occurs.

Included in inventory for commercial aircraft programs are amounts paid or credited in cash, or other consideration to certain airline customers, that are referred to as early issue sales consideration. Early issue sales consideration is recognized as a reduction to revenue when the delivery of the aircraft under contract occurs. If an airline customer does not perform and take delivery of the contracted aircraft, we believe that we would have the ability to recover amounts paid. However, to the extent early issue sales consideration exceeds advances and is not considered to be otherwise recoverable, it would be written off in the current period.

We net advances and progress billings on long-term contracts against inventory in the Consolidated Statements of Financial Position. Advances and progress billings in excess of related inventory are reported in Advances and billings in excess of related costs.

Precontract Costs

We may, from time to time, incur costs to begin fulfilling the statement of work under a specific anticipated contract that we are still negotiating with a customer. If we determine it is probable that we will be awarded the specific anticipated contract, then we capitalize the precontract costs we incur, excluding start-up costs which are expensed as incurred. Capitalized precontract costs are included in Inventories, net of advances and progress billings, in the accompanying Consolidated Statements of Financial Position. Should the contract not be awarded or otherwise determined to no longer be probable of award, the capitalized costs would be written off.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost, including applicable construction-period interest, less accumulated depreciation and are depreciated principally over the following estimated useful lives: new buildings and land improvements, from 10 to 40 years; and new machinery and equipment, from 3 to 20 years. The principal methods of depreciation are as follows: buildings and land improvements,

60

150% declining balance; and machinery and equipment, sum-of-the-years’ digits. Capitalized internal use software is included in Other assets and amortized using the straight line method over five years. We periodically evaluate the appropriateness of remaining depreciable lives assigned to long-lived assets, including assets that may be subject to a management plan for disposition.

Long-lived assets held for sale are stated at the lower of cost or fair value less cost to sell. Long-lived assets held for use are subject to an impairment assessment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the carrying value is no longer recoverable based upon the undiscounted future cash flows of the asset, the amount of the impairment is the difference between the carrying amount and the fair value of the asset.

Asset Retirement Obligations

We record all known asset retirement obligations for which the liability’s fair value can be reasonably estimated, including certain asbestos removal, asset decommissioning and contractual lease restoration obligations. Recorded amounts are not material.

We also have known conditional asset retirement obligations, such as certain asbestos remediation and asset decommissioning activities to be performed in the future, that are not reasonably estimable due to insufficient information about the timing and method of settlement of the obligation. Accordingly, these obligations have not been recorded in the Consolidated Financial Statements. A liability for these obligations will be recorded in the period when sufficient information regarding timing and method of settlement becomes available to make a reasonable estimate of the liability’s fair value. In addition, there may be conditional asset retirement obligations that we have not yet discovered (e.g. asbestos may exist in certain buildings but we have not become aware of it through the normal course of business), and therefore, these obligations also have not been included in the Consolidated Financial Statements.

Goodwill and Other Acquired Intangibles

Goodwill and other acquired intangible assets with indefinite lives are not amortized, but are tested for impairment annually and when an event occurs or circumstances change such that it is more likely than not that an impairment may exist. Our annual testing date is April 1.

We test goodwill for impairment by first comparing the carrying value of net assets to the fair value of the related operations. If the fair value is determined to be less than carrying value, a second step is performed to compute the amount of the impairment. In this process, a fair value for goodwill is estimated, based in part on the fair value of the operations, and is compared to its carrying value. The shortfall of the fair value below carrying value represents the amount of goodwill impairment.

Indefinite-lived intangibles consist of brand and tradenames acquired in business combinations. We test these intangibles for impairment by comparing their carrying value to current projections of discounted cash flows attributable to the brand and tradenames. Any excess carrying value over the amount of discounted cash flows represents the amount of the impairment.

Our finite-lived acquired intangible assets are amortized on a straight-line basis over their estimated useful lives as follows: developed technology, from 4 to 14 years; product know-how, from 3 to 30 years; customer base, from 3 to 19 years; distribution rights, from 3 to 30 years; and other, from 1 to 32 years. We evaluate the potential impairment of finite-lived acquired intangible assets whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the carrying value is no longer recoverable based upon the undiscounted future cash flows of the asset, the amount of the impairment is the difference between the carrying amount and the fair value of the asset.

61

Investments

Time deposits are held-to-maturity investments that are carried at cost.

The equity method of accounting is used to account for investments for which we have the ability to exercise significant influence, but not control, over an investee. Significant influence is generally deemed to exist if we have an ownership interest in the voting stock of an investee of between 20% and 50%.

We classify investment income and loss on our Consolidated Statements of Operations based on whether the investment is operating or non-operating in nature. Operating investments align strategically and are integrated with our operations. Earnings from operating investments, including our share of income or loss from equity method investments, dividend income from certain cost method investments, and any impairments or gain/loss on the disposition of these investments, are recorded in Income from operating investments, net. Non-operating investments are those we hold for non-strategic purposes. Earnings from non-operating investments, including interest and dividends on marketable securities, and any impairments or gain/loss on the disposition of these investments are recorded in Other income/(expense), net.

Derivatives

All derivative instruments are recognized in the financial statements and measured at fair value regardless of the purpose or intent of holding them. We use derivative instruments to principally manage a variety of market risks. For derivatives designated as hedges of the exposure to changes in fair value of the recognized asset or liability or a firm commitment (referred to as fair value hedges), the gain or loss is recognized in earnings in the period of change together with the offsetting loss or gain on the hedged item attributable to the risk being hedged. The effect of that accounting is to include in earnings the extent to which the hedge is not effective in achieving offsetting changes in fair value. For our cash flow hedges, the effective portion of the derivative’s gain or loss is initially reported in Shareholders’ equity (as a component of Accumulated other comprehensive loss) and is subsequently reclassified into earnings in the same period or periods during which the hedged forecasted transaction affects earnings. The ineffective portion of the gain or loss of a cash flow hedge is reported in earnings immediately. We also hold certain instruments for economic purposes that are not designated for hedge accounting treatment. For these derivative instruments, the changes in their fair value are also recorded in earnings immediately.

Aircraft Valuation

Used aircraft under trade-in commitments and aircraft under repurchase commitments In conjunction with signing a definitive agreement 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. Additionally, we have entered into contingent repurchase commitments with certain customers wherein we agree to repurchase the Sale Aircraft at a specified price, generally 10 to 15 years after delivery of the Sale Aircraft. Our repurchase of the Sale Aircraft is contingent upon a future, mutually acceptable agreement for the sale of additional new aircraft. If we execute an agreement for the sale of additional new aircraft, and if the customer exercises its right to sell the Sale Aircraft to us, a contingent repurchase commitment would become a trade-in commitment. Our historical experience is that contingent repurchase commitments infrequently become trade-in commitments.

62

All trade-in commitments at December 31, 2011 and 2010 were solely attributable to Sale Aircraft and did not originate from contingent repurchase commitments. Exposure related to trade-in commitments may take the form of:

(1) adjustments to revenue for the difference between the contractual trade-in price in the definitive agreement and our best estimate of the fair value of the trade-in aircraft as of the date of such agreement, which would be recorded in Inventory and recognized upon delivery of the Sale Aircraft, and/or

(2) charges to cost of products for adverse changes in the fair value of trade-in aircraft that occur subsequent to signing of a definitive agreement for Sale Aircraft but prior to the purchase of the used trade-in aircraft. Estimates based on current aircraft values would be included in Accrued liabilities.

The fair value of trade-in aircraft is determined using aircraft-specific data such as model, age and condition, market conditions for specific aircraft and similar models, and multiple valuation sources. This process uses our assessment of the market for each trade-in aircraft, which in most instances begins years before the return of the aircraft. There are several possible markets in which we continually pursue opportunities to place used aircraft. These markets include, but are not limited to, the resale market, which could potentially include the cost of long-term storage; the leasing market, with the potential for refurbishment costs to meet the leasing customer’s requirements; or the scrap market. Trade-in aircraft valuation varies significantly depending on which market we determine is most likely for each aircraft. On a quarterly basis, we update our valuation analysis based on the actual activities associated with placing each aircraft into a market. This quarterly valuation process yields results that are typically lower than residual value estimates by independent sources and tends to more accurately reflect results upon the actual placement of the aircraft.

Used aircraft acquired by the Commercial Airplanes segment are included in Inventories at the lower of cost or market as it is our intent to sell these assets. To mitigate costs and enhance marketability, aircraft may be placed on operating lease. While on operating lease, the assets are included in Customer financing.

Assets under operating lease, assets held for sale or re-lease and collateral underlying receivables Customer financing includes operating lease equipment, notes receivables, and sales-type/finance leases. Sales-type/finance leases are treated as receivables, and allowances for losses are established as necessary.

We assess the fair value of the assets we own, including equipment under operating leases, assets held for sale or re-lease, and collateral underlying receivables, to determine if their fair values are less than the related assets’ carrying values. Differences between carrying values and fair values of sales-type/finance leases and notes and other receivables, as determined by collateral value, are considered in determining the allowance for losses on receivables.

We use a median calculated from published collateral values from multiple third-party aircraft value publications based on the type and age of the aircraft to determine the fair value of aircraft. Under certain circumstances, we apply judgment based on the attributes 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 outside publications.

Impairment review for assets under operating leases and held for sale or re-lease We evaluate for impairment assets under operating lease or assets held for sale or re-lease when events or changes in circumstances indicate that the expected undiscounted cash flow from the asset may be less than the carrying value. We use various assumptions when determining the expected

63

undiscounted cash flow, including our intentions for how long we will hold an asset subject to operating lease before it is sold, the expected future lease rates, lease terms, residual value of the asset, periods in which the asset may be held in preparation for a follow-on lease, maintenance costs, remarketing costs and the remaining economic life of the asset. We record assets held for sale at the lower of carrying value or fair value less costs to sell.

When we determine that impairment is indicated for an asset, the amount of impairment expense recorded is the excess of the carrying value over the fair value of the asset.

Allowance for losses on customer financing receivables We record the potential impairment of customer financing receivables in our portfolio in a valuation account, the balance of which is an accounting estimate of probable but unconfirmed losses in the receivables portfolio. The allowance for losses on receivables relates to two components of receivables: (a) receivables that are evaluated individually for impairment and (b) all other receivables.

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 of the receivable agreement, without regard to any subsequent restructurings. Factors considered in assessing collectibility include, but are not limited to, a customer’s extended delinquency, requests for restructuring and filings for bankruptcy. We determine a specific impairment allowance based on the difference between the carrying value of the receivable and the estimated fair value of the related collateral we would expect to realize.

We review the adequacy of the allowance attributable to the remaining receivables (after excluding receivables subject to a specific impairment allowance) by assessing both the collateral exposure and the applicable cumulative default rate. Collateral exposure for a particular receivable is the excess of the carrying value of the receivable over the fair value of the related collateral. A receivable with an estimated fair value in excess of the carrying value is considered to have no collateral exposure. The applicable cumulative default rate is determined using two components: customer credit ratings and weighted average remaining contract term. Internally assigned credit ratings, our credit quality indicator, are determined for each customer in the portfolio. Those ratings are updated based upon public information and information obtained directly from our customers.

We have entered into agreements with certain customers that would entitle us to look beyond the specific collateral underlying the receivable for purposes of determining the collateral exposure as described above. Should the proceeds from the sale of the underlying collateral asset resulting from a default condition be insufficient to cover the carrying value of our receivable (creating a shortfall condition), these agreements would, for example, permit us to take the actions necessary to sell or retain certain other assets in which the customer has an equity interest and use the proceeds to cover the shortfall.

Each quarter we review customer credit ratings, published historical credit default rates for different rating categories, and multiple third-party aircraft value publications as a basis to validate the reasonableness of the allowance for losses on receivables. There can be no assurance that actual results will not differ from estimates or that the consideration of these factors in the future will not result in an increase or decrease to the allowance for losses on receivables.

Warranties

In conjunction with certain product sales, we provide warranties that cover factors such as non-conformance to specifications and defects in material and design. The majority of our warranties are issued by our Commercial Airplanes segment. Generally, aircraft sales are accompanied by a three

64

to four-year standard warranty for systems, accessories, equipment, parts, and software manufactured by us or manufactured to certain standards under our authorization. These warranties are included in the programs’ estimate at completion. On occasion we have made commitments beyond the standard warranty obligation to correct fleet-wide major issues of a particular model, resulting in additional accrued warranty expense. Warranties issued by our BDS segments principally relate to sales of military aircraft and weapons hardware and are included in the contract cost estimates. These sales are generally accompanied by a six to twelve-month warranty period and cover systems, accessories, equipment, parts, and software manufactured by us to certain contractual specifications. Estimated costs related to standard warranties are recorded in the period in which the related product sales occur. The warranty liability recorded at each balance sheet date reflects the estimated number of months of warranty coverage outstanding for products delivered times the average of historical monthly warranty payments, as well as additional amounts for certain major warranty issues that exceed a normal claims level. Estimated costs of these additional warranty issues are considered changes to the initial liability estimate.

We provide guarantees to certain commercial airplane customers which include compensation provisions for failure to meet specified aircraft performance targets. We account for these performance guarantees as warranties. The estimated liability for these warranties is based on known and anticipated operational characteristics and forecasted customer operation of the aircraft relative to contractually specified performance targets, and anticipated settlements when contractual remedies are not specified. Estimated payments are recorded as a reduction of revenue at delivery of the related aircraft. We have agreements that require certain suppliers to compensate us for amounts paid to customers for failure of supplied equipment to meet specified performance targets. Claims against suppliers under these agreements are included in Inventories and recorded as a reduction in Cost of products at delivery of the related aircraft. These performance warranties and claims against suppliers are included in the programs’ estimate at completion.

Supplier Penalties

We record an accrual for supplier penalties when an event occurs that makes it probable that a supplier penalty will be incurred and the amount is reasonably estimable. Until an event occurs, we fully anticipate accepting all products procured under production-related contracts.

Guarantees

We record a liability in Accrued liabilities for the fair value of guarantees that are issued or modified after December 31, 2002. For a residual value guarantee where we received a cash premium, the liability is equal to the cash premium received at the guarantee’s inception. For credit and performance guarantees, the liability is equal to the present value of the expected loss. We determine the expected loss by multiplying the creditor’s default rate by the guarantee amount reduced by the expected recovery, if applicable, for each future period the credit or performance guarantee will be outstanding. If at inception of a guarantee, we determine there is a probable related contingent loss, we will recognize a liability for the greater of (a) the fair value of the guarantee as described above or (b) the probable contingent loss amount.

As of December 31, 2011 and 2010, we had indefinite-lived intangible assets with carrying amounts of $497 and $499 relating to tradenames.

The gross carrying amounts and accumulated amortization of our acquired finite-lived intangible assets were as follows at December 31:

	2011				2010
	Gross Carrying Amount		Accumulated Amortization		Gross Carrying Amount		Accumulated Amortization

Note 4 – Earnings Per Share

The weighted-average number of shares outstanding used to compute earnings per share are as follows:

(Shares in millions) Years ended December 31,	2011		2010		2009
Weighted average shares outstanding		744.1		735.0		705.9
Participating securities		2.5		3.1		3.7
Basic weighted average shares outstanding		746.6		738.1		709.6
Dilutive potential common shares		6.5		6.2		3.8
Diluted weighted average shares outstanding		753.1		744.3		713.4

Basic earnings per share is calculated by the sum of (1) net earnings less declared dividends and dividend equivalents related to share-based compensation divided by the basic weighted average shares outstanding and (2) declared dividends and dividend equivalents related to share-based compensation divided by the weighted average shares outstanding.

The weighted average number of shares outstanding, included in the table below, were excluded from the computation of diluted earnings per share because the average market price did not exceed the exercise/threshold price. However, these shares may be dilutive potential common shares in the future.

(Shares in millions) Years ended December 31,	2011		2010		2009
Stock options		21.1		14.9		16.8
Performance Awards		1.5		3.8		2.0
ShareValue Trust						13.2
Performance Shares						0.8
Stock Units						0.2

Note 5 – Income Taxes

The components of earnings before income taxes were:

Years ended December 31,	2011		2010		2009
U.S.	$	5,083	$	4,310	$	1,638
Non-U.S.		310		197		93
Total	$	5,393	$	4,507	$	1,731

Income tax expense/(benefit) consisted of the following:

Years ended December 31,	2011			2010			2009
Current tax expense
U.S. federal	$	(605	)	$	13		$	(132	)
Non-U.S.		93			80			69
U.S. state		(22	)		(137	)		145
Total current		(534	)		(44	)		82
Deferred tax expense
U.S. federal		1,856			969			457
Non-U.S.		(8	)		(13	)		(55	)
U.S. state		68			284			(88	)
Total deferred		1,916			1,240			314
Total income tax expense	$	1,382		$	1,196		$	396

68

Net income tax payments/(refunds) were $57, $360, and $(198) in 2011, 2010 and 2009, respectively.

Our effective income tax rate was 25.6%, 26.5%, and 22.9% for the years ended December 31, 2011, 2010 and 2009, respectively. Our 2011 effective tax rate was lower than 2010, primarily due to an income tax charge of $150 recorded during the first quarter of 2010 as a result of the Patient Protection and Affordable Care Act, as modified by the Health Care and Education Reconciliation Act of 2010. Our 2010 effective tax rate was higher than 2009, primarily because pre-tax book income in 2010 was higher than in 2009 and because of the income tax charge of $150 recorded during the first quarter of 2010. This was partially offset by a tax benefit of $371 recorded during the fourth quarter of 2010 as a result of settling the 1998-2003 federal audit. The following is a reconciliation of the U.S. federal statutory tax rate of 35% to our effective income tax rate:

Years ended December 31,	2011			2010			2009
U.S. federal statutory tax		35.0	%		35.0	%		35.0	%
Research and development credits		(2.7	)		(3.5	)		(10.1	)
Tax on international activities		(0.6	)		(1.2	)		(2.4	)
Tax deductible dividends		(0.8	)		(0.9	)		(2.2	)
State income tax provision, net of effect on U.S. federal tax		0.7			1.8			2.2
Medicare Part D law change					3.3
Federal audit settlement		(7.4	)		(8.2	)
Other provision adjustments		1.4			0.2			0.4
Effective income tax rate		25.6	%		26.5	%		22.9	%

During the fourth quarter of 2011, a tax benefit of $397 was recorded as a result of settling the 2004-2006 federal tax audit. During the fourth quarter we received an audit report for the 2007-2008 IRS examination for which we are filing an appeal. We are also subject to examination in major state and international jurisdictions for the 2001-2011 tax years. We believe appropriate provisions for all outstanding tax issues have been made for all jurisdictions and all open years.

Significant components of our deferred tax assets, net of deferred tax liabilities, at December 31 were as follows:

	2011			2010
Retiree health care accruals	$	2,820		$	3,061
Inventory and long-term contract methods of income recognition, fixed assets and other (net of valuation allowance of $27 and $27)		(5,189	)		(2,644	)
Partnerships and joint ventures		(228	)		(263	)
Other employee benefits accruals		1,352			1,272
In-process research and development related to acquisitions		51			65
Net operating loss, credit and capital loss carryovers (net of valuation allowance of $74 and $78)		488			300
Pension asset		5,315			3,443
Customer and commercial financing		(1,471	)		(1,645	)
Unremitted earnings of non-U.S. subsidiaries		(66	)		(60	)
Other net unrealized losses		69			13
Net deferred tax assets(1)	$	3,141		$	3,542

⁽¹⁾  Of the deferred tax asset for net operating loss and credit carryovers, $336 expires in years ending from December 31, 2012 through December 31, 2031 and $152 may be carried over indefinitely.

69

Net deferred tax assets at December 31 were as follows:

	2011			2010
Deferred tax assets	$	16,181		$	14,383
Deferred tax liabilities		(12,939	)		(10,736	)
Valuation allowance		(101	)		(105	)
Net deferred tax assets	$	3,141		$	3,542

The measurement of deferred tax assets is reduced by a valuation allowance if, based upon available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. Included in the net deferred tax assets at December 31, 2011 and 2010 are deferred tax assets in the amounts of $9,743 and $8,186 related to Accumulated other comprehensive loss.

We have provided for U.S. deferred income taxes and foreign withholding tax in the amount of $66 on undistributed earnings not considered permanently reinvested in our non-U.S. subsidiaries. We have not provided for U.S. deferred income taxes or foreign withholding tax on the remainder of undistributed earnings from our non-U.S. subsidiaries because such earnings are considered to be permanently reinvested and it is not practicable to estimate the amount of tax that may be payable upon distribution.

As of December 31, 2011 and 2010, the amounts accrued for the payment of income tax-related interest and penalties included in the Consolidated Statements of Financial Position were as follows: interest of $48 and $170 and penalties of $10 and $12. The amounts of interest (benefit)/expense were ($94), ($105), and $45 for the years ended December 31, 2011, 2010, and 2009, respectively. The interest benefits recorded during 2011 and 2010 were primarily related to the 2004-2006 and 1998-2003 federal audit settlements.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

	2011			2010			2009
Unrecognized tax benefits – January 1	$	1,198		$	1,787		$	1,453
Gross increases – tax positions in prior periods		154			95			219
Gross decreases – tax positions in prior periods		(383	)		(465	)		(31	)
Gross increases – current-period tax positions		28			76			148
Gross decreases – current-period tax positions		(15	)		(40	)
Settlements		(42	)		(254	)
Lapse of statute of limitations		(1	)		(1	)		(2	)
Unrecognized tax benefits – December 31	$	939		$	1,198		$	1,787

As of December 31, 2011, 2010 and 2009, the total amount of unrecognized tax benefits was $939, $1,198, and $1,787 of which $838, $1,074, and $1,452 would affect the effective tax rate, if recognized. As of December 31, 2011, these amounts are primarily associated with U.S. federal tax issues such as the amount of research and development tax credits claimed, the domestic production activities deductions claimed, and U.S. taxation of foreign earnings. Also included in these amounts are accruals for domestic state tax issues such as the allocation of income among various state tax jurisdictions and the amount of state tax credits claimed.

The research and development credit expired on December 31, 2011. Members of Congress have introduced bills that would extend the credit. If the Research and Development credit is not extended there would be an unfavorable impact to our 2012 effective income tax rate. For the years ended December 31, 2011, 2010 and 2009, the Research and Development credit reduced our effective tax rate by 2.7%, 3.5%, and 10.1%, respectively.

Note 6 – Accounts Receivable

Accounts receivable at December 31 consisted of the following:

	2011			2010
U.S. government contracts	$	2,950		$	2,969
Commercial customers		1,390			1,241
Reinsurance receivables		585			487
Non-U.S. military contracts		553			514
Other		368			253
Less valuation allowance		(53	)		(42	)
Total	$	5,793		$	5,422

The following table summarizes our accounts receivable under long-term contracts that were not billable or related to outstanding claims as of December 31:

	Unbillable				Claims
	2011		2010		2011		2010
Current	$	1,174	$	994	$	49	$	30
Expected to be collected after one year		498		507		209		194
Total	$	1,672	$	1,501	$	258	$	224

Under contract accounting unbillable receivables on long-term contracts arise when the sales or revenues based on performance attainment, though appropriately recognized, cannot be billed yet under terms of the contract as of the balance sheet date. Any adjustment for the credit quality of unbillable receivables, if required, would be recorded as a direct reduction of revenue. Factors considered in assessing the collectability of unbillable receivables include, but are not limited to, a customer’s extended delinquency, requests for restructuring and filings for bankruptcy. Unbillable receivables related to commercial customers expected to be collected after one year were $192 and $213 at December 31, 2011 and 2010. Accounts receivable related to claims are items that we believe are earned, but are subject to uncertainty concerning their determination or ultimate realization. Accounts receivable, other than those described above, expected to be collected after one year are not material.

Note 7 – Inventories

Inventories at December 31 consisted of the following:

	2011			2010
Long-term contracts in progress	$	13,587		$	14,400
Commercial aircraft programs		35,080			26,550
Commercial spare parts, used aircraft, general stock materials and other		7,832			5,788
Inventory before advances and progress billings		56,499			46,738
Less advances and progress billings		(24,259	)		(22,421	)
Total	$	32,240		$	24,317

Long-Term Contracts in Progress

Long-term contracts in progress included Delta launch program inventory that will be sold at cost to United Launch Alliance (ULA) under an inventory supply agreement that terminates on March 31, 2021. At December 31, 2011 and 2010, the inventory balance was $1,085 and $1,385. As of December 31, 2011, $739 of this inventory relates to yet unsold launches. ULA is continuing to assess the future of the Delta II program. In the event ULA is unable to sell additional Delta II inventory, our earnings could be reduced by up to $58. See Note 13.

Inventory balances included $236 subject to claims or other uncertainties relating to the A-12 program as of December 31, 2011 and 2010. See Note 21.

Capitalized precontract costs of $1,728 and $527 at December 31, 2011 and 2010, are included in long-term contracts in progress inventories.

Commercial Aircraft Programs

As of December 31, 2011 and 2010, commercial aircraft programs inventory included the following amounts related to the 787 program: $16,098 and $9,461 of work in process (including deferred production costs at December 31, 2011 of $10,753), $1,770 and $1,956 of supplier advances, and $1,914 and $1,447 of unamortized tooling and other non-recurring costs. At December 31, 2011, $9,168 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 $3,499 is expected to be recovered from units included in the program accounting quantity that represent expected future orders.

Commercial aircraft programs inventory included the following amounts related to the 747 program: $448 of deferred production costs at December 31, 2011, net of previously recorded reach-forward losses, and $852 and $879 of unamortized tooling costs at December 31, 2011 and 2010. During the third quarter of 2011, we reclassified $1,934 of previously recorded reach-forward losses on the 747 program from Accrued liabilities to Inventories, net of advances and progress billings. At December 31, 2011, $903 of 747 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 $397 is expected to be recovered from units included in the program accounting quantity that represent expected future orders.

Commercial aircraft program inventory included amounts credited in cash or other consideration (early issue sales consideration), to airline customers totaling $2,564 and $1,970 at December 31, 2011 and 2010.

As a normal course of our Commercial Airplanes segment production process, our inventory may include a small quantity of airplanes that are completed but unsold. As of December 31, 2011, these aircraft were valued at $509. As of December 31, 2010 the value of completed but unsold aircraft in inventory was insignificant.

Note 8 – Customer Financing

Customer financing at December 31 consisted of the following:

	2011			2010
Financing receivables:
Investment in sales-type/finance leases	$	2,037		$	2,272
Notes		814			480
Operating lease equipment, at cost, less accumulated depreciation of $765 and $847		1,991			2,281
Gross customer financing		4,842			5,033
Less allowance for losses on receivables		(70	)		(353	)
Total	$	4,772		$	4,680

The components of investment in sales-type/finance leases at December 31 were as follows:

	2011			2010
Minimum lease payments receivable	$	2,272		$	2,879
Estimated residual value of leased assets		541			619
Unearned income		(776	)		(1,226	)
Total	$	2,037		$	2,272

Operating lease equipment primarily includes large commercial jet aircraft and regional jet aircraft. At December 31, 2011 and 2010, operating lease equipment included $521 and $583 of equipment available for sale or re-lease. At December 31, 2011 and 2010, we had firm lease commitments for $476 and $28 of this equipment.

When our Commercial Airplanes segment is unable to immediately sell used aircraft, it may place the aircraft under an operating lease. It may also provide customer financing with a note receivable. The carrying amount of the Commercial Airplanes segment used aircraft under operating leases and notes receivable included as a component of customer financing totaled $357 and $167 as of December 31, 2011 and 2010.

Financing receivable balances evaluated for impairment at December 31 were as follows:

	2011		2010
Individually evaluated for impairment	$	854	$	99
Collectively evaluated for impairment		1,997		2,653
Total financing receivables	$	2,851	$	2,752

Of the $854 and $99 of financing receivables individually evaluated for impairment as of December 31, 2011 and 2010, $485 and $0, were classified as impaired. We recorded no allowance for losses on these impaired receivables.

The average recorded investment in impaired financing receivables for the years ended December 31, 2011, 2010 and 2009, was $517, $88 and $162, respectively. Income recognition is generally suspended for financing receivables at the date full recovery of income and principal becomes not probable. Income is recognized when financing receivables become contractually current and performance is demonstrated by the customer. As of December 31, 2011, we had no interest income recognized on such receivables and $9 and $9 for the years ended December 31, 2010 and 2009, respectively.

73

The change in the allowance for losses on financing receivables for the years ended December 31, 2011, 2010 and 2009, consisted of the following:

	2011			2010			2009
Beginning balance – January 1	$	(353	)	$	(302	)	$	(269	)
Customer financing valuation benefit/(provision)		269			(51	)		(45	)
Reduction in customer financing assets		14						12
Ending balance – December 31	$	(70	)	$	(353	)	$	(302	)
Individually evaluated for impairment							$	(2	)
Collectively evaluated for impairment	$	(70	)	$	(353	)		(300	)

We assign internal credit ratings for all customers and determine the creditworthiness of each customer based upon public information and information obtained directly from our customers. We utilize these credit ratings as one of the factors in assessing the adequacy of our allowance for losses on receivables. Our rating categories are comparable to those used by the major credit rating agencies. The customer financing valuation benefit recorded in 2011 was primarily driven by changes in the internal credit rating categories assigned to our receivable balances from AirTran Holdings, LLC (AirTran).

The following table details our financing receivable balances at December 31, by the internal credit rating category which was used as a factor in determining our allowance for losses on receivables.

Rating categories	2011		2010
BBB	$	1,316
BB		67
B		103	$	207
CCC		512		2,432
D		653
Other		200		113
Total carrying value of financing receivables	$	2,851	$	2,752

At December 31, 2011, our allowance primarily related to receivables with ratings of BBB and CCC and we applied default rates that averaged 4% and 48% to exposure associated with those receivables. On May 2, 2011, Southwest Airlines Co. (Southwest) completed its acquisition of AirTran Holdings, Inc. and AirTran Holdings, Inc. became a wholly owned subsidiary of Southwest. AirTran became the successor to AirTran Holdings, Inc. As a result, we took into account Southwest’s credit rating when we determined the allowance for losses on AirTran receivables during 2011. In the fourth quarter of 2011, we revised the contractual terms of our leases with AirTran in conjunction with receiving a full guarantee from Southwest which guaranteed AirTran’s obligations to BCC. At December 31, 2011 and 2010, we assigned the internal rating categories of BBB and CCC to the receivables from AirTran for the purpose of assigning default rates discussed above. The improved rating in 2011 reduced the allowance for losses on receivables by $241 for the year ended December 31, 2011.

In the fourth quarter of 2011, American Airlines filed for Chapter 11 bankruptcy protection. We believe that our customer financing receivables from American Airlines of $653 are sufficiently collateralized such that we do not expect to incur losses related to those receivables as a result of the bankruptcy.

Declines in collateral values are also a significant driver of our allowance for losses. Generally, out-of-production aircraft have had greater percentages of collateral value declines than in-production aircraft. Our portfolio consists primarily of financing receivables for out-of-production aircraft.

74

As of December 31, 2011 and 2010, we had no material receivables that were greater than 30 days past due.

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 may be subject to reduced valuation with market decline. Our customer financing portfolio has a concentration of various model aircraft. Customer financing carrying values related to major aircraft concentrations at December 31 were as follows:

	2011		2010
717 Aircraft ($480 and $561 accounted for as operating leases)(1)	$	1,906	$	2,070
757 Aircraft ($451 and $629 accounted for as operating leases)(1)		631		720
737 Aircraft ($242 and $317 accounted for as operating leases)		394		366
767 Aircraft ($103 and $115 accounted for as operating leases)		307		372
MD-11 Aircraft ($321 and $327 accounted for as operating leases)(1)		321		327

⁽¹⁾  Out of production aircraft

Charges related to customer financing asset impairment for the years ended December 31 were as follows:

	2011			2010		2009
Boeing Capital Corporation	$	109		$	85	$	91
Other Boeing		(36	)		85		8
Total	$	73		$	170	$	99

Scheduled receipts on customer financing are as follows:

Year	2012		2013		2014		2015		2016		Beyond 2016
Principal payments on notes receivable	$	243	$	196	$	105	$	52	$	37	$	181
Sales-type/finance lease payments receivable		326		285		226		225		221		989
Operating lease equipment payments receivable		219		185		164		153		84		125

Customer financing assets leased under capital leases and subleased to others were not significant in 2011 and 2010.

Note 9 – Property, Plant and Equipment

Rental expense for leased properties was $270, $269 and $273, for the years ended December 31, 2011, 2010 and 2009, respectively. At December 31, 2011, minimum rental payments under capital leases aggregated $197. Minimum rental payments under operating leases with initial or remaining terms of one year or more aggregated $1,311, net of sublease payments of $4, at December 31, 2011. Non-cancellable future rentals due from customers for equipment on operating leases aggregated $105 at December 31, 2011. Payments due under operating and capital leases net of sublease amounts, and non-cancellable future rentals during the next five years are as follows:

	2012		2013		2014		2015		2016

Our effective ownership percentages and balances of equity method investments consisted of the following as of December 31:

	Segment	Ownership Percentages			Investment Balance
					2011			2010
United Launch Alliance	Network & Space Systems		50	%	$	983		$	950

Total Equity method investments					$	1,003		$	1,072

76

⁽¹⁾  Credit balances are a result of our proportionate share of the joint venture’s pension and postretirement related adjustments which reduce the carrying value of the investment.

Note 11 – Other Assets

Sea Launch

At December 31, 2011, 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 October 19, 2009, we filed a Notice of Arbitration with the Stockholm Chamber of Commerce seeking reimbursement from the other Sea Launch partners of the $147 bank guarantee payment. On October 7, 2010, the arbitrator ruled that the Stockholm Chamber of Commerce lacked jurisdiction to hear the matter but did not resolve the merits of our claim. We filed a notice appealing the arbitrator’s ruling on January 11, 2011. No legal proceedings have commenced against the partners on the partner loans. We 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 loans made to Sea Launch, we could incur additional pre-tax charges of up to $356.

Note 12 – Liabilities, Commitments and Contingencies

Accrued Liabilities

Accrued liabilities at December 31 consisted of the following:

	2011		2010
Accrued Compensation and employee benefit costs	$	5,546	$	5,193
Environmental		758		721
Product warranties		1,046		1,076
Forward loss recognition(1)		501		2,743
Other		4,388		4,069
Total	$	12,239	$	13,802

⁽¹⁾  Forward loss recognition in 2011 relates primarily to the Airborne Early Warning and Control program (AEW&C). $1,934 of loss related to the 747 Program included in the 2010 balance was reclassified to inventory during 2011.

Environmental

The following table summarizes environmental remediation during the years ended December 31, 2011 and 2010.

	2011			2010
Beginning balance – January 1	$	721		$	706
Reductions for payments made		(118	)		(93	)
Changes in estimates		155			108
Ending balance – December 31	$	758		$	721

77

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 the discovery of additional contamination. As part of our estimating process, we develop a range of reasonably possible alternate scenarios which include 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 December 31, 2011 and 2010, the high end of the estimated range of reasonably possible remediation costs exceeded our recorded liabilities by $1,003 and $957.

Product Warranties

The following table summarizes product warranty activity recorded for the years ended December 31, 2011 and 2010.

	2011			2010
Beginning balance – January 1	$	1,076		$	999
Additions for current year deliveries		232			141
Reductions for payments made		(269	)		(234	)
Changes in estimates		7			170
Ending balance – December 31	$	1,046		$	1,076

Commercial Aircraft Commitments

In conjunction with signing definitive agreements for the sale of new aircraft (Sale Aircraft), we have entered into specified-price trade-in commitments with certain customers that give them the right to trade in used aircraft upon the purchase of Sale Aircraft. The total contractual trade-in value was $273 and $295 as of December 31, 2011 and 2010. We anticipate that a significant portion of these commitments will not be exercised by customers.

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 take into consideration the current economic environment. 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. The fair value of trade-in aircraft related to probable contractual trade-in commitments was $27 and $30 as of December 31, 2011 and 2010. Trade-in commitment agreements have expiration dates from 2012 through 2023.

78

Financing Commitments

Financing commitments totaled $15,866 and $9,865 as of December 31, 2011 and 2010. The estimated earliest potential funding dates for these commitments as of December 31, 2011 are as follows:

	Total
2012	$	1,562
2013		1,207
2014		2,217
2015		3,639
2016		2,475
Thereafter		4,766
	$	15,866

Standby Letters of Credit and Surety Bonds

We have entered into standby letters of credit agreements 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 $6,199 and $7,599 as of December 31, 2011 and 2010.

Commitments to ULA

We and Lockheed have each committed to provide ULA with up to $352 of additional capital contributions in the event ULA does not have sufficient funds to make a required payment to us under an inventory supply agreement. See Note 7.

C-17

At December 31, 2011, our backlog included 3 C-17 aircraft currently under contract with the U.S. Air Force (USAF) as well as international orders for 2 aircraft. The probable orders, not under contract at December 31, 2011, totaled 19 aircraft of which 13 were for international customers and 6 for the USAF. USAF orders included 5 aircraft for which a contract was received in January 2012 and 1 aircraft which was funded in the Fiscal Year 2012 Defense Appropriations Act. At December 31, 2011, we had approximately $940 of inventory expenditures and potential termination liabilities to suppliers associated with probable orders, of which $870 was related to the 5 USAF orders and 12 international orders received in January and February 2012. We completed the planned production rate decrease from 15 aircraft per year to 10 per year during the third quarter of 2011. The associated reduction in headcount resulted in pension curtailment charges of $34 in the first quarter of 2011. Should additional orders not materialize, it is reasonably possible that we will decide in 2012 to end production of the C-17 at a future date. We are still evaluating the full financial impact of a potential production shut-down, including additional pension curtailment charges, and any recovery that would be available from the U.S. government. Such recovery from the U.S. government would not include the costs incurred by us resulting from our direction to suppliers to begin working on aircraft beyond those currently under contract with the USAF.

F-15

At December 31, 2011, we had approximately $2,275 of inventory expenditures and potential termination liabilities to suppliers related to the production of F-15 aircraft not currently under contract.

79

On December 29^th, 2011, the Kingdom of Saudi Arabia and the U.S. government announced the signing of a letter of offer and acceptance for a foreign military sale for 84 new F-15SE Eagle fighters and associated products and services. We expect this order to be under contract in 2012.

Company Owned Life Insurance

McDonnell Douglas Corporation insured its executives with Company Owned Life Insurance (COLI), which are life insurance policies with a cash surrender value. Although we do not use COLI currently, these obligations from the merger with McDonnell Douglas are still a commitment at this time. We have loans in place to cover costs paid or incurred to carry the underlying life insurance policies. As of December 31, 2011 and 2010, the cash surrender value was $397 and $381 and the total loans were $377 and $363. As we have the right to offset the loans against the cash surrender value of the policies, we present the net asset in Other assets on the Consolidated Statements of Financial Position as of December 31, 2011 and 2010.

Note 13 – 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 tables provide 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.

	Maximum Potential Payments				Estimated Proceeds from Collateral/ Recourse				Carrying Amount of Liabilities
December 31,	2011		2010		2011		2010		2011		2010

Contingent Repurchase Commitments We have entered into contingent repurchase commitments with certain customers in conjunction with signing definitive agreements for the sale of new aircraft. Under these commitments, we agreed to repurchase the Sale Aircraft at a specified price, generally 10 to 15 years after delivery of the Sale Aircraft. Our repurchase of the Sale Aircraft is contingent upon a future, mutually acceptable agreement for the sale of additional new aircraft, and the subsequent exercise by the customer of its right to sell the Sale Aircraft to us. 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 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

80

March 31, 2021. Since inception, ULA has consumed $1,211 of inventory that was contributed by us. ULA has made advance payments of $720 to us and we have recorded revenues and cost of sales of $483 under the inventory supply agreement through December 31, 2011. ULA is continuing to assess the future of the Delta II program beyond what is currently on contract. In the event ULA is unable to sell additional Delta II inventory, our earnings could be reduced by up to $58.

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. The DCMA has not yet issued a final decision related to the recoverability of the $114. 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. ULA has until June 2012 to file a suit with the Court of Federal Claims for collection of deferred support costs. 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.

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 for a third satellite mission. During the third quarter of 2010, ULA submitted 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. In March 2011, ULA filed a notice of appeal before the ASBCA, seeking to re-price the third mission. A hearing before the ASBCA has been scheduled for May 6, 2013. If ULA is unsuccessful in obtaining additional pricing, we may be responsible for a portion of the shortfall and may record up to $279 in pre-tax losses associated with the three missions, representing up to $261 for the indemnification payment and up to $18 for our portion of additional contract losses incurred by ULA.

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 nine years.

Residual Value Guarantees We have issued various residual value guarantees principally to facilitate the sale and financing of certain commercial aircraft. Under these guarantees, we are obligated to make payments to the guaranteed party if the related aircraft or equipment fair values fall below a specified amount at a future time. These obligations are collateralized principally by the underlying commercial aircraft and expire within the next seven years.

Other Indemnifications As part of the 2004 sale agreement with General Electric Capital Corporation related to the sale of Boeing Capital Corporation’s (BCC) Commercial Financial Services business, BCC is involved in a loss sharing arrangement for losses on transferred portfolio assets, such as asset sales, provisions for loss or asset impairment charges offset by gains from asset sales. At December 31, 2011 and 2010, our maximum future cash exposure to losses associated with the loss sharing arrangement was $212 and $232 and our accrued liability under the loss sharing arrangement was $51 and $82.

81

In conjunction with our sales of the Electron Dynamic Devices, Inc. and Rocketdyne Propulsion and Power businesses and the sale of our Commercial Airplanes facilities in Wichita, Kansas and Tulsa and McAlester, Oklahoma in 2005, we agreed to indemnify, for an indefinite period, the buyers for costs relating to pre-closing environmental contamination and certain other items. As it is impossible to assess whether there will be damages in the future or the amounts thereof (if any), we cannot estimate the maximum potential amount of future payments under these indemnities. Therefore, no liability has been recorded. There have been no claims submitted to date.

Industrial Revenue Bonds

Industrial Revenue Bonds (IRBs) issued by the City of Wichita were used to finance the purchase and/or construction of real and personal property at our Wichita site. Tax benefits associated with IRBs include a ten-year property tax abatement and a sales tax exemption from the Kansas Department of Revenue. We record the property on our Consolidated Statements of Financial Position, along with a capital lease obligation to repay the proceeds of the IRB. We have also purchased the IRBs and therefore are the bondholders as well as the borrower/lessee of the property purchased with the IRB proceeds.

The capital lease obligation and IRB asset are recorded net in the Consolidated Statements of Financial Position. As of December 31, 2011 and 2010, the net assets associated with the City of Wichita IRBs were $783 and $822.

Note 14 – Debt

On August 1, 2011, BCC issued notes totaling $750, which included $500 bearing an interest rate of 2.125% due August 15, 2016 and $250 bearing an interest rate of 2.90% due August 15, 2018. The net proceeds after deducting the discount, underwriting fees and issuance costs were $745. The notes are unsecured senior obligations and rank equally in right of payment with all of BCC’s existing and future unsecured and unsubordinated indebtedness.

Total debt interest incurred, including amounts capitalized, was $683, $729 and $610 for the years ended December 31, 2011, 2010 and 2009, respectively. Interest expense recorded by BCC is reflected as a separate line item on our Consolidated Statements of Operations, and is included in Earnings from operations. Total Company interest payments were $626, $670 and $502 for the years ended December 31, 2011, 2010 and 2009, respectively.

We have $4,600 currently available under credit line agreements, of which $2,300 is a 364-day revolving credit facility expiring in November 2012 and $2,300 is a five-year credit facility expiring in November 2016. The 364-day credit facility has a one-year term out option which allows us to extend the maturity of any borrowings one year beyond the aforementioned expiration date. We have given BCC exclusive access to $750 under the 364-day facility and $750 under the five-year facility. We continue to be in full compliance with all covenants contained in our debt or credit facility agreements, including those at BCC.

Note 15 – Postretirement Plans

The majority of our employees are covered by defined benefit pension plans. All nonunion and some union employees hired after December 31, 2008 are not covered by defined benefit plans. We fund our major pension plans through trusts. Pension assets are placed in trust solely for the benefit of the plans’ participants, and are structured to maintain liquidity that is sufficient to pay benefit obligations as well as to keep pace over the long-term with the growth of obligations for future benefit payments.

We also have other postretirement benefits (OPB) other than pensions which consist principally of health care coverage for eligible retirees and qualifying dependents, and to a lesser extent, life insurance to certain groups of retirees. Retiree health care is provided principally until age 65 for approximately half those retirees who are eligible for health care coverage. Certain employee groups, including employees covered by most United Auto Workers bargaining agreements, are provided lifetime health care coverage.

83

The funded status of the plans is measured as the difference between the plan assets at fair value and the projected benefit obligation (PBO). We have recognized the aggregate of all overfunded plans in Pension plan assets, net, and the aggregate of all underfunded plans in either Accrued retiree health care or Accrued pension plan liability, net. The portion of the amount by which the actuarial present value of benefits included in the PBO exceeds the fair value of plan assets, payable in the next 12 months, is reflected in Accrued liabilities.

The components of net periodic benefit cost are as follows:

	Pension									Other Postretirement Plans
Years ended December 31,	2011			2010			2009			2011			2010			2009
Service cost	$	1,406		$	1,176		$	1,090		$	221		$	121		$	132
Interest cost		3,116			3,002			2,964			484			404			466
Expected return on plan assets		(3,741	)		(3,850	)		(3,738	)		(6	)		(6	)		(5	)
Amortization of prior service costs		244			248			242			(96	)		(78	)		(90	)
Recognized net actuarial loss		1,254			777			650			178			56			92
Settlement/curtailment/transfer loss		64			14			13			3
Net periodic benefit cost	$	2,343		$	1,367		$	1,221		$	784		$	497		$	595
Net periodic benefit cost included in Earnings from operations	$	1,648		$	1,101		$	879		$	692		$	480		$	615

During the quarter ended September 30, 2011, we determined the accumulated benefit obligation (ABO) for certain other postretirement benefit plans was understated. As a result, we recognized an additional $294 of postretirement benefit obligations at September 30, 2011. This increased net periodic benefit cost during 2011 by $184, which includes service cost of $73, interest cost of $68 and recognized net actuarial loss of $43. Had the understatement been recorded at December 31, 2010, the postretirement benefit obligation would have increased by $274 from $8,546 to $8,820. Management believes that these understatements were not material to the current period or prior periods.

Under our accounting policy, a portion of net periodic benefit cost is allocated to production as inventoried costs. Of the $184 increase in net periodic benefit cost described above, the associated cost included in Earnings from operations was $161 for the quarter ended September 30, 2011, with the remaining cost of $23 classified as inventory.

84

The following tables show changes in the benefit obligation, plan assets and funded status of both pensions and OPB for the years ended December 31, 2011 and 2010. Benefit obligation balances presented below reflect the PBO for our pension plans, and accumulated postretirement benefit obligations (APBO) for our OPB plans.

Amounts recognized in Accumulated other comprehensive loss at December 31 are as follows:

	Pension				Other Postretirement Benefits
	2011		2010		2011			2010
Net actuarial loss	$	24,448	$	19,343	$	1,885		$	2,148

The estimated amount that will be amortized from Accumulated other comprehensive loss into net periodic benefit cost during the year ended December 31, 2012 is as follows:

	Pensions		Other Postretirement Benefits
Recognized net actuarial loss	$	1,935	$	123
Amortization of prior service costs/(credits)		226		(197	)
Total	$	2,161	$	(74	)

The ABO for all pension plans was $61,902 and $53,513 at December 31, 2011 and 2010. Key information for our plans with ABO in excess of plan assets as of December 31 is as follows:

	2011		2010
Projected benefit obligation	$	67,418	$	58,772
Accumulated benefit obligation		61,675		53,202
Fair value of plan assets		50,820		48,926

The Patient Protection and Affordable Care Act, as modified by the Health Care and Education Reconciliation Act of 2010 increased our APBO by $300 at December 31, 2010. This includes the impact of the excise tax on high cost health plans scheduled to become payable beginning in 2018. This increase is recognized as an actuarial loss and is amortized over the expected future service of current employees.

Assumptions

The following assumptions, which are the weighted average for all plans, are used to calculate the benefit obligation at December 31 of each year and the net periodic benefit cost for the subsequent year.

December 31,	2011			2010			2009
Discount rate:
Pension		4.40	%		5.30	%		5.80	%
Other postretirement benefits		4.00	%		4.90	%		5.40	%
Expected return on plan assets		7.75	%		7.75	%		8.00	%
Rate of compensation increase		3.90	%		5.20	%		5.50	%

The discount rate for each plan is determined based on the plans’ expected future benefit payments using a yield curve developed from high quality bonds that are rated as Aa or better by Moody’s as of the measurement date. The yield curve is fitted to yields developed from bonds at various maturity points. Bonds with the ten percent highest and the ten percent lowest yields are omitted. A portfolio of about 400 bonds is used to construct the yield curve. Since corporate bond yields are generally not available at maturities beyond 30 years, it is assumed that spot rates will remain level beyond that 30-year point. The present value of each plan’s benefits is calculated by applying the spot/discount rates to projected benefit cash flows. All bonds are U.S. issues, with a minimum outstanding of $50.

The pension fund’s expected return on plan assets assumption is derived from a review of actual historical returns achieved by the pension trust and anticipated future long-term performance of individual asset classes. While consideration is given to recent trust performance and historical returns,

86

the assumption represents a long-term, prospective return. The expected return on plan assets component of the net periodic benefit cost for the upcoming plan year is determined based on the expected return on plan assets assumption and the market-related value of plan assets (MRVA). Since our adoption of the accounting standard for pensions in 1987, we have determined the MRVA based on a five-year moving average of plan assets. As of December 31, 2011, the MRVA is approximately $790 less than the fair market value of assets.

Assumed health care cost trend rates were as follows:

December 31,	2011			2010			2009
Health care cost trend rate assumed next year		7.50	%		7.50	%		7.00	%
Ultimate trend rate		5.00	%		5.00	%		5.00	%
Year that trend reached ultimate rate		2018			2018			2014

Assumed health care cost trend rates have a significant effect on the amounts reported for the health care plans. To determine the health care cost trend rates we look at a combination of information including ongoing claims cost monitoring, annual statistical analyses of claims data, reconciliation of forecast claims against actual claims, review of trend assumptions of other plan sponsors and national health trends, and adjustments for plan design changes, workforce changes, and changes in plan participant behavior. A one-percentage-point change in assumed health care cost trend rates would have the following effect:

	Increase		Decrease
Effect on total of service and interest cost	$	63	$	(54	)
Effect on postretirement benefit obligation		642		(572	)

Plan Assets

Investment Strategy The overall objective of our pension assets is to earn a rate of return over time to satisfy the benefit obligations of the pension plans and to maintain sufficient liquidity to pay benefits and address other cash requirements of the pension fund. Specific investment objectives for our long-term investment strategy include reducing the volatility of pension assets relative to pension liabilities, achieving a competitive, total investment return, achieving diversification between and within asset classes and managing other risks. Investment objectives for each asset class are determined based on specific risks and investment opportunities identified.

We periodically update our long-term, strategic asset allocations. We use various analytics to determine the optimal asset mix and consider plan liability characteristics, liquidity characteristics, funding requirements, expected rates of return and the distribution of returns. We identify investment benchmarks for the asset classes in the strategic asset allocation that are market-based and investable where possible.

Actual allocations to each asset class vary from target allocations due to periodic investment strategy changes, market value fluctuations, the length of time it takes to fully implement investment allocation positions (such as private equity and real estate), and the timing of benefit payments and contributions. Short term investments and exchange-traded derivatives are used to rebalance the actual asset allocation to the target asset allocation. The asset allocation is monitored and rebalanced on a monthly basis.

87

The actual allocations for the pension assets at December 31 and target allocations by asset class, are as follows:

	Percentage of Plan Assets						Target Allocations
Asset Class	2011			2010			2011			2010
Fixed income		53	%		49	%		49	%		45	%
Global equity		26			33			30			28
Private equity		6			5			6			6
Real estate and real assets		6			5			6			10
Global strategies		4			4			4			5
Hedge funds		5			4			5			6
Total		100	%		100	%		100	%		100	%

Fixed income securities are invested broadly and primarily in long duration instruments. Global equity securities are invested broadly in U.S. and non-U.S. companies which are in various industries and countries and through a range of market capitalizations.

Real estate and real assets include global private investments and publicly traded investments (such as REITs in the case of real estate). Real estate includes but is not limited to investments in office, retail, apartment and industrial properties. Real assets include but are not limited to investments in natural resources (such as energy, farmland and timber), commodities and infrastructure. Private equity investment vehicles are primarily limited partnerships (LPs) and fund-of-funds that mainly invest in U.S. and non-U.S. leveraged buyout, venture capital and special situation strategies.

Global strategies seek to capitalize on inefficiencies identified across different asset classes or markets, primarily using long-short positions in derivatives and physical securities. Hedge fund strategy types include, but are not limited to event driven, relative value, long-short and market neutral. A well-diversified number of hedge funds are held.

Investment managers are retained for explicit investment roles specified by contractual investment guidelines. Certain investment managers are authorized to invest in derivatives, such as equity or bond futures, swaps, options and currency futures or forwards. Derivatives are used to achieve the desired market exposure of a security or an index, transfer value-added performance between asset classes, achieve the desired currency exposure, adjust portfolio duration or rebalance the total portfolio to the target asset allocation.

As a percentage of total plan assets, derivative net notional amounts were 3.9% and 9.8% for fixed income, including to-be-announced mortgage-backed securities and treasury forwards, and 3.5% and negative 0.2% for global equity and currency overlay at December 31, 2011 and 2010.

In November 2009, the Company elected to contribute $1,500 of our common stock to the pension fund. An independent fiduciary was retained to manage and liquidate the stock over time at its discretion. The liquidation of the common stock holdings was completed during 2011.

Risk Management In managing the plan assets, we review and manage risk associated with funded status risk, interest rate risk, market risk, counterparty risk, liquidity risk and operational risk. Liability management and asset class diversification are central to our risk management approach and are integral to the overall investment strategy. Further, asset classes are constructed to achieve diversification by investment strategy, by investment manager, by industry or sector and by holding. Investment manager guidelines for publicly traded assets are specified and are monitored regularly through the custodian. Credit parameters for counterparties have been established for managers permitted to trade over-the-counter derivatives.

88

Fair Value Measurements The following table presents our plan assets using the fair value hierarchy as of December 31, 2011 and 2010. 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 non-observable inputs.

	December 31, 2011											December 31, 2010

Fixed income securities are primarily valued using a market approach with inputs that include broker quotes, benchmark yields, base spreads and reported trades.

Cash equivalents and other short-term investments, which are used to pay benefits, are primarily held in registered money market funds which are valued using a market approach based on the quoted market prices of identical instruments. Other cash equivalent and short-term investments are valued daily by the fund using a market approach with inputs that include quoted market prices for similar instruments.

89

Common and preferred stock equity securities are primarily valued using a market approach based on the quoted market prices of identical instruments. Common/collective/pooled funds are typically common or collective trusts valued at their net asset values (NAVs) that are calculated by the investment manager or sponsor of the fund and have daily or monthly liquidity. Active currency managers, through an overlay program, invest in a broad set of currency derivatives. Derivatives leveled in the table above are over-the-counter and are primarily valued using an income approach with inputs that include benchmark yields, swap curves, cash flow analysis, rating agency data and interdealer broker rates. Exchange-traded derivative positions are reported in accordance with changes in daily variation margin which is settled daily and therefore reflected in the payables and receivables portion of the table.

Private equity valuations are reported by the fund manager and are based on the valuation of the underlying investments, which include inputs such as cost, operating results, discounted future cash flows and market based comparable data.

Real estate and real asset fund values are primarily reported by the fund manager and are based on valuation of the underlying investments, which include inputs such as cost, discounted future cash flows, independent appraisals and market based comparable data. Publically traded REITs and infrastructure stocks are valued using a market approach based on quoted market prices of identical instruments. Exchange-traded commodities futures positions are reported in accordance with changes in daily variation margin which is settled daily and therefore reflected in the payables and receivables portion of the table.

Global strategies are primarily limited liability company (LLC) or mutual fund structures. The LLCs are primarily valued using a market approach based on NAVs calculated by the fund and have monthly liquidity. Global strategies mutual funds are valued using a market approach based on the quoted market prices of identical instruments.

Hedge funds consist of fund-of-fund LLC or commingled fund structures and direct hedge funds. The LLCs are primarily valued using a market approach based on NAVs calculated by the fund and are not publicly available. Liquidity for the LLCs is monthly and is subject to liquidity of the underlying hedge funds. The commingled fund NAV is calculated by the manager on a daily basis and has monthly liquidity. Direct hedge funds are primarily valued by each fund’s third party administrator based on valuation of the underlying securities and instruments and primarily applying a market or income valuation methodology depending on the specific type of security or instrument, equity, fixed income, currency or derivative, held. Direct hedge fund NAVs based on valuation of the underlying holdings are not publicly available and have monthly liquidity.

Some of our assets, primarily our private equity, real estate and real assets, hedge funds and global strategies, do not have readily determinable market values given the specific investment structures involved and the nature of the underlying investments. For the December 31, 2011 and 2010 plan asset reporting, publicly traded asset pricing was used where possible. For assets without readily determinable values, estimates were derived from investment manager discussions focusing on underlying fundamentals and significant events. For those investments reported on a one-quarter lagged basis (primarily LPs) we use net asset values, adjusted for subsequent cash flows and significant events.

OPB Plan Assets The majority of OPB plan assets are invested in a balanced index fund which is comprised of approximately 60% equities and 40% debt securities. The index fund is valued using a market approach based on the quoted market price of an identical instrument (Level 1). The expected rate of return on these assets does not have a material effect on the net periodic benefit cost.

Cash Flows

Contributions Required pension contributions under the Employee Retirement Income Security Act (ERISA) as well as rules governing funding of our non-U.S. pension plans, are expected to be minimal in 2012. We expect to make discretionary contributions to our plans of approximately $1,500 in 2012. We expect to contribute approximately $15 to our OPB plans in 2012.

91

Estimated Future Benefit Payments The table below reflects the total pension benefits expected to be paid from the plans or from our assets, including both our share of the benefit cost and the participants’ share of the cost, which is funded by participant contributions. OPB payments reflect our portion only.

Year(s)	2012			2013			2014			2015			2016			2017–2021
Pensions	$	2,829		$	2,979		$	3,140		$	3,313		$	3,448		$	19,501

Net other postretirement benefits	$	477		$	498		$	522		$	546		$	575		$	3,225

Termination Provisions

Certain of the pension plans provide that, in the event there is a change in control of the Company which is not approved by the Board of Directors and the plans are terminated within five years thereafter, the assets in the plan first will be used to provide the level of retirement benefits required by ERISA, and then any surplus will be used to fund a trust to continue present and future payments under the postretirement medical and life insurance benefits in our group insurance benefit programs.

We have an agreement with the U.S. government with respect to certain pension plans. Under the agreement, should we terminate any of the plans under conditions in which the plan’s assets exceed that plan’s obligations, the U.S. government will be entitled to a fair allocation of any of the plan’s assets based on plan contributions that were reimbursed under U.S. government contracts.

Defined Contribution Plans

We provide certain defined contribution plans to all eligible employees. The principal plans are the Company-sponsored 401(k) plans. The expense for these defined contribution plans was $658, $614 and $591 in 2011, 2010 and 2009, respectively.

Note 16 – Share-Based Compensation and Other Compensation Arrangements

Share-Based Compensation

Our 2003 Incentive Stock Plan, as amended and restated effective February 21, 2011, permits awards of incentive stock options, nonqualified stock options, restricted stock, stock units, performance shares, performance units and other incentives to our employees, officers, consultants and independent contractors. The aggregate number of shares of our stock available for issuance under the amended plan will not exceed 80,000,000 and no more than an aggregate of 16,000,000 shares are available for issuance as restricted stock awards.

Shares issued as a result of stock option exercises or conversion of stock unit awards will be funded out of treasury shares, except to the extent there are insufficient treasury shares, in which case new shares will be issued. We believe we currently have adequate treasury shares to meet any requirements to issue shares during 2012.

92

Share-based plans expense is primarily included in General and administrative expense since it is incentive compensation issued primarily to our executives. The share-based plans expense and related income tax benefit follow:

Years ended December 31,	2011		2010		2009
Stock options	$	88	$	96	$	111
Restricted stock units and other awards		98		83		56
ShareValue Trust				36		71
Share-based plans expense	$	186	$	215	$	238
Income tax benefit	$	73	$	83	$	89

Stock Options

In February 2011, 2010 and 2009, we granted to our executives 5,426,910, 5,932,806 and 7,423,242 options, respectively. The options have been granted with an exercise price equal to the fair market value of our stock on the date of grant and expire ten years after the date of grant. The stock options granted after 2005 vest over a period of three years, with 34% vesting after the first year, 33% vesting after the second year and the remaining 33% vesting after the third year. If an executive terminates employment for any reason, the non-vested portion of the stock option will not vest and all rights to the non-vested portion will terminate completely.

Stock option activity for the year ended December 31, 2011 is as follows:

	Shares			Weighted Average Exercise Price Per Share		Weighted Average Remaining Contractual Life (Years)		Aggregate Intrinsic Value
Number of shares under option:
Outstanding at beginning of year		28,975,442		$	65.96
Granted		5,658,705			71.29
Exercised		(2,447,099	)		46.88
Forfeited		(665,482	)		61.11
Expired		(90,171	)		61.88
Outstanding at end of year		31,431,395		$	68.52		6.58	$	290
Exercisable at end of year		20,488,535		$	71.77		5.51	$	170

The total intrinsic value of options exercised was $67, $59 and $2 during the years ended December 31, 2011, 2010 and 2009, respectively. Cash received from options exercised for the years ended December 31, 2011, 2010 and 2009 was $114, $87 and $10 with a related tax benefit of $23, $20 and $1, respectively, derived from the compensation deductions resulting from these option exercises. At December 31, 2011, there was $89 of total unrecognized compensation cost related to the Stock Option plan which is expected to be recognized over a weighted average period of 1.8 years. The grant date fair value of stock options vested during the years ended December 31, 2011, 2010 and 2009 was $92, $103 and $114, respectively.

93

The fair values of options were estimated using the Black-Scholes option-pricing model with the following assumptions:

Grant Year	Grant Date		Expected Life		Expected Volatility			Dividend Yield			Risk Free Interest Rate			Weighted-Average Grant Date Fair Value Per Share
2011		2/22/2011		6 years		29.8	%		2.3	%		2.5	%	$	17.96
2010		2/22/2010		6 years		31.5	%		3.0	%		2.9	%	$	15.70
2009		2/23/2009		6 years		39.0	%		2.4	%		2.0	%	$	11.12

The expected volatility of the stock options is based on a combination of our historical stock volatility and the volatility levels implied on the grant date by actively traded option contracts on our common stock. We determined the expected term of the stock option grants to be six years, calculated using the “simplified” method in accordance with the SEC Staff Accounting Bulletin 110. We use the “simplified” method since we changed the vesting terms, tax treatment and the recipients of our stock options beginning in 2006 such that we believe our historical data no longer provides a reasonable basis upon which to estimate expected term and we do not have enough option exercise data from our grants issued subsequent to 2006 to support our own estimate.

Restricted Stock Units

In February 2011, 2010 and 2009, we granted to our executives 1,364,440, 1,459,256 and 2,144,501 restricted stock units (RSUs) as part of our long-term incentive program with grant date fair values of $71.44, $63.83 and $35.57 per share, respectively. The RSUs vest on the third anniversary of the grant date. If an executive terminates employment because of retirement, involuntary layoff, disability, or death, the employee (or beneficiary) will immediately vest on a proration of stock units based on active employment during the three-year service period. In all other cases, the RSUs will not vest and all rights to the stock units will terminate completely.

In addition to RSUs awarded under our long-term incentive program, we grant RSUs to certain executives and employees to encourage retention or to reward various achievements. These RSUs are labeled other restricted stock units in the table below. The fair values of all RSUs are estimated using the average stock price on the date of grant. Stock units settle in common stock on a one-for-one basis and are not contingent upon stock price.

Stock unit activity for the year ended December 31, 2011 is as follows:

	Incentive Program Restricted Stock Units			Other Restricted Stock Units
Number of units:
Outstanding at beginning of year		3,425,800			1,701,951
Granted		1,421,906			197,526
Dividends		104,895			37,848
Forfeited		(152,608	)		(32,721	)
Distributed		(112,759	)		(410,436	)
Outstanding at end of year		4,687,234			1,494,168
Unrecognized compensation cost	$	98		$	23
Weighted average remaining contractual life (years)		1.8			1.9

Other Compensation Arrangements

Performance Awards

Performance Awards are cash units that pay out based on the achievement of long-term financial goals at the end of a three-year period. Each unit has an initial value of $100 dollars per unit. The amount payable at the end of the three-year performance period may be anywhere from $0 to $200 dollars per unit, depending on the Company’s performance against plan for a three-year period. The Compensation Committee has the discretion to pay these awards in cash, stock, or a combination of both after the three-year performance period. Compensation expense, based on the estimated performance payout, is recognized ratably over the performance period.

During 2011, 2010 and 2009, we granted Performance Awards to our executives with the payout based on the achievement of financial goals for each three-year period following the grant date. The minimum payout amount is $0 and the maximum amount we could be required to pay out for the 2011, 2010 and 2009 Performance Awards is $265, $246 and $285, respectively. The 2009 grant is expected to be paid out in cash in March 2012.

Deferred Compensation

The Company has a deferred compensation plan which permits executives to defer receipt of a portion of their salary, bonus, and certain other incentive awards. Participants can diversify deferred compensation among 19 investment funds including a Boeing stock unit account.

Total expense related to deferred compensation was $59, $112 and $158 in 2011, 2010 and 2009, respectively. As of December 31, 2011 and 2010, the deferred compensation liability which is being marked to market was $1,093 and $1,149.

ShareValue Trust

The ShareValue Trust, established July 1, 1996, was a 14-year irrevocable trust that held shares of our common stock, received dividends, and distributed to employees the appreciation in value above a 3% per annum threshold rate of return at the end of each period. The trust was terminated effective July 1, 2010 with the 29,948,920 undistributed shares returned to the Company.

Note 17 – Shareholders’ Equity

On October 29, 2007, the Board approved the repurchase of up to $7,000 of common stock (the Program). Unless terminated earlier by a Board resolution, the Program will expire when we have used all authorized funds for repurchase. At December 31, 2011, $3,610 in shares may still be purchased under the Program.

As of December 31, 2011 and 2010, there were 1,200,000,000 shares of common stock and 20,000,000 shares of preferred stock authorized. No preferred stock has been issued.

Note 18 – Derivative Financial Instruments

Cash Flow Hedges

Our cash flow hedges include foreign currency forward contracts, foreign currency option contracts, commodity swaps, and commodity purchase contracts. We use foreign currency forward and option 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 principally occurring within five years in the future, with certain contracts hedging transactions up to 2021. We use commodity derivatives, such as swaps and fixed-price purchase commitments, to hedge against potentially unfavorable price changes for items used in production. These include commitments to purchase electricity at fixed prices through 2016.

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 BCC interest expense.

Derivative Instruments Not Receiving Hedge Accounting Treatment

We also hold certain derivative instruments, primarily foreign currency forward contracts, for risk management purposes but without electing any form of hedge accounting.

96

Notional Amounts and Fair Values

The notional amounts and fair values of derivative instruments in the Consolidated Statements of Financial Position as of December 31 were as follows:

	Notional amounts(1)				Other assets						Accrued liabilities
	2011		2010		2011			2010			2011			2010
Derivatives designated as hedging instruments:

Netting arrangements						(61	)		(71	)		61			71
Net recorded balance					$	155		$	227		$	(131	)	$	(115	)

⁽¹⁾  Notional amounts represent the gross contract/notional amount of the derivatives outstanding.

Gains/(losses) associated with our cash flow and undesignated hedging transactions and their effect on other comprehensive loss and Net earnings were as follows:

Years ended December 31,	2011			2010
Effective portion recognized in other comprehensive loss, net of taxes:
Foreign exchange contracts	$	12		$	67
Commodity contracts		(25	)		(30	)
Effective portion reclassified out of Accumulated other comprehensive loss into earnings, net of taxes:
Foreign exchange contracts		42			25
Commodity contracts		(26	)		(16	)
Forward points recognized in Other income/(expense), net:
Foreign exchange contracts		37			(3	)
Undesignated derivatives recognized in Other income/(expense), net:
Foreign exchange contracts	$	(21	)	$	(33	)

Based on our portfolio of cash flow hedges, we expect to reclassify gains of $4 (pre-tax) out of Accumulated other comprehensive loss into earnings during the next 12 months. Ineffectiveness related to our hedges was insignificant for the years ended December 31, 2011 and 2010.

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, expiring November 2016. For 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 December 31, 2011 was $39. At December 31, 2011, there was no collateral posted related to our derivatives.

97

Note 19 – Significant Group Concentrations of Risk

Credit Risk

Financial instruments involving potential credit risk are predominantly with commercial aircraft customers and the U.S. government. Of the $10,688 in gross accounts receivable and gross customer financing included in the Consolidated Statements of Financial Position as of December 31, 2011, $4,968 related predominantly to commercial aircraft customers ($660 of accounts receivable and $4,308 of customer financing) and $2,950 related to the U.S. government.

Of the $4,842 in gross customer financing, $2,817 related to customers we believe have less than investment-grade credit including American Airlines, United/Continental Airlines, and Hawaiian Airlines who were associated with 14%, 9% and 8%, respectively, of our financing portfolio. Financing for aircraft is collateralized by security in the related asset and in some instances security in other assets as well.

As of December 31, 2011, there was $15,866 of financing commitments related to aircraft on order including options and proposed as part of sales campaigns described in Note 12, of which $14,697 related to customers we believe have less than investment-grade credit.

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. Significant BDS fixed-price development contracts include Airborne Early Warning and Control (AEW&C), India P-8I, 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 also result in lower margins or a material charge for reach-forward losses in 2012.

Commercial Airplane Development Programs

The development and initial production of new commercial airplanes and new commercial airplane derivatives entail significant commitments to customers and suppliers as well as substantial investments in working capital, infrastructure and research and development. Performance issues or cost overruns on these programs, which currently include the 787 and 747-8, could have a material impact on our consolidated results and financial position in 2012.

Other Risk

As of December 31, 2011, approximately 37% of our total workforce was represented by collective bargaining agreements and approximately 13% of our total workforce was represented by agreements expiring during 2012.

98

Note 20 – Fair Value Measurements

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. 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 non-observable inputs.

	December 31, 2011										December 31, 2010
	Total			Level 1		Level 2			Level 3		Total			Level 1		Level 2			Level 3
Assets
Money market funds	$	3,104		$	3,104						$	3,337		$	3,337
Available-for-sale investments		10			5				$	5		15			10				$	5
Derivatives		155				$	155					227				$	227
Total assets	$	3,269		$	3,109	$	155		$	5	$	3,579		$	3,347	$	227		$	5
Liabilities
Derivatives	$	(131	)			$	(131	)			$	(115	)			$	(115	)
Total liabilities	$	(131	)			$	(131	)			$	(115	)			$	(115	)

Money market funds and available-for-sale equity securities are valued using a market approach based on the quoted market prices of identical instruments. Available-for-sale debt investments are primarily valued using an income approach based on benchmark yields, reported trades and broker/dealer quotes.

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 years ended December 31, and the carrying value and asset classification of the related assets as of December 31:

	2011					2010
	Carrying Value		Total Losses			Carrying Value		Total Losses
Operating lease equipment	$	72	$	(64	)	$	247	$	(143	)
Property, plant and equipment		3		(35	)				(4	)
Other assets, Acquired intangible assets, Cost investment		20		(11	)
Total	$	95	$	(110	)	$	247	$	(147	)

The operating lease equipment was valued using a market approach based on the fair value of the related aircraft. Property, plant and equipment, Other assets, and Acquired intangible assets were valued using an income approach based on the discounted cash flows associated with the underlying assets. The cost investment was valued using a market approach based on quoted market prices for related investments.

Fair Value Disclosures

The fair values and related carrying values of financial instruments that are not required to be remeasured at fair value on the Consolidated Statement of Financial Position at December 31 were as follows:

	2011						2010
	Carrying Amount			Fair Value			Carrying Amount			Fair Value
Assets
Accounts receivable, net	$	5,793		$	5,690		$	5,422		$	5,283
Notes receivable, net		792			836			480			501
Liabilities
Debt, excluding capital lease obligations		(12,136	)		(14,099	)		(12,234	)		(13,525	)
Accounts payable		(8,406	)		(8,396	)		(7,715	)		(7,704	)
Residual value and credit guarantees		(8	)		(9	)		(12	)		(11	)
Contingent repurchase commitments		(7	)		(4	)		(7	)		(84	)

The fair values of the Accounts receivable and Accounts payable are 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 using 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 is based on current market yields for our debt traded in the secondary market. The fair values of the residual value guarantees and contingent repurchase commitments are determined using a Black Futures Options formula and include such assumptions as the expected value of the aircraft on the settlement date, volatility of aircraft prices, time until settlement and the risk free discount rate. The fair value of the credit guarantees is estimated based on the expected cash flows of those commitments, given the creditor’s probability of default, and discounted using the risk free rate. With regard to other financial instruments with off-balance sheet risk, it is not practicable to estimate the fair value of our indemnifications because the amount and timing of those arrangements are uncertain. Items not included in the above disclosures include cash and cash equivalents, restricted cash, time deposits and other deposits, commercial paper and long-term payables. The carrying values of those items, as reflected in the Consolidated Statements of Financial Position, approximate their fair value at December 31, 2011 and 2010.

Note 21 – Legal Proceedings

Various legal proceedings, claims and investigations related to products, contracts and other matters are pending against us. Potentially material contingencies are discussed below.

We are subject to various U.S. government investigations, from which civil, criminal or administrative proceedings could result or have resulted. 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 government disputes and investigations will not have a material effect on our financial position, results of operations, or cash flows, except as set forth below. 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 have disclosed 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.

A-12 Litigation

In 1991, the Department of the Navy (the Navy) notified McDonnell Douglas Corporation (now merged into The Boeing Company) and General Dynamics Corporation (together, the Team) that it was terminating for default the Team’s contract for development and initial production of the A-12 aircraft.

The Team had full responsibility for performance of the contract and both contractors are jointly and severally liable for any potential liabilities resulting from the termination. The Team filed a legal action to contest the Navy’s default termination, to assert its rights to convert the termination to one for “the convenience of the government,” and to obtain payment for work done and costs incurred on the A-12 contract but not paid to date. As of December 31, 2011, inventories included approximately $586 of recorded costs on the A-12 contract, against which we have established a loss provision of $350. The amount of the provision, which was established in 1990, was based on McDonnell Douglas Corporation’s belief, supported by an opinion of outside counsel, that the termination for default would be converted to a termination for convenience, and that the best estimate of possible loss on termination for convenience was $350.

On August 31, 2001, the U.S. Court of Federal Claims issued a decision after trial upholding the government’s default termination of the A-12 contract. In 2003, the Court of Appeals for the Federal Circuit, finding that the trial court had applied the wrong legal standard, vacated the trial court’s 2001 decision and ordered the case sent back to the trial court for further proceedings. On May 3, 2007, the U.S. Court of Federal Claims issued a decision upholding the government’s default termination of the A-12 contract. We filed a Notice of Appeal on May 4, 2007 with the Court of Appeals for the Federal Circuit. On June 2, 2009, the Court of Appeals rendered an opinion affirming the trial court’s 2007 decision sustaining the government’s default termination. On May 23, 2011, the U.S. Supreme Court vacated the decision of the Court of Appeals upholding the default termination, and remanded the case to the Court of Appeals. On July 7, 2011, the Court of Appeals remanded the case to the trial court for additional factual determinations. On December 29, 2009, the Navy sent letters to the Team requesting payment of $1,352 in unliquidated progress payments, plus applicable interest. On November 15, 2011, the Navy sent a letter confirming that it would not pursue payment from the Team pending all trial court and appellate proceedings adjudicating the issues remanded by the Supreme Court.

We believe that the termination for default is contrary to law and fact and that the loss provision established by McDonnell Douglas Corporation in 1990, which was supported by an opinion from outside counsel, continues to provide adequately for the reasonably possible reduction in value of A-12 net contracts in process as of December 31, 2011. Final resolution of the A-12 litigation will depend on the outcome of further proceedings or possible negotiations with the U.S. government. If after all legal proceedings are concluded, the court determines, contrary to our belief, that a termination for default was appropriate, we could incur an additional loss of up to $275, consisting principally of $236 of remaining inventory costs. If the courts further hold that a money judgment should be entered against the Team, we could be required to pay the U.S. government up to one-half of the unliquidated progress payments of $1,350 plus statutory interest from February 1991 (currently totaling up to $1,565). In that event, our loss would total approximately $1,728 in pre-tax charges. Should, however, the March 31, 1998 judgment of the U.S. Court of Federal Claims in favor of the Team be reinstated, we could be entitled to receive payment of approximately $1,177, including interest from June 26, 1991.

Employment, Labor and Benefits Litigation

We have been named as a defendant in two pending class action lawsuits filed in the U.S. District Court for the District of Kansas, each related to the 2005 sale of our former Wichita facility to Spirit AeroSystems, Inc. (Spirit). The first action involves allegations that Spirit’s hiring decisions following the sale were tainted by age discrimination, violated ERISA, violated our collective bargaining

101

agreements, and constituted retaliation. The case was brought in 2006 as a class action on behalf of individuals not hired by Spirit. During the second quarter of 2010, the court granted summary judgment in favor of Boeing and Spirit on all class action claims. Following certain procedural motions, plaintiffs filed a notice of appeal to the Tenth Circuit Court of Appeals on August 10, 2011, and are seeking to stay all remaining individual claims in the district court pending resolution of the appeal. Plaintiffs’ appellate brief was filed on November 14, 2011. Boeing’s appellate brief was filed on January 20, 2012.

The second action, initiated in 2007, alleges collective bargaining agreement breaches and ERISA violations in connection with alleged failures to provide benefits to certain former employees of the Wichita facility. Written discovery closed by joint stipulation of the parties on June 6, 2011. Depositions concluded on August 18, 2011. Plaintiffs’ partial motion for summary judgment was filed on December 9, 2011. Boeing’s opposition and dispositive motions are due on February 10, 2012. Spirit has agreed to indemnify Boeing for any and all losses in the first action, with the exception of claims arising from employment actions prior to January 1, 2005. While Spirit has acknowledged a limited indemnification obligation in the second action, we believe that Spirit is obligated to indemnify Boeing for any and all losses in the second action.

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. The 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. During the first quarter of 2010, the Seventh Circuit Court of Appeals granted a stay of trial proceedings in the district court pending resolution of an appeal made by Boeing in 2008 to the case’s class certification order. On January 21, 2011, the Seventh Circuit reversed the district court’s class certification order and decertified the class. The Seventh Circuit remanded the case to the district court for further proceedings. On March 2, 2011, plaintiffs filed an amended motion for class certification and a supplemental motion on August 7, 2011. Boeing’s opposition to class certification was filed on September 6, 2011. Plaintiffs’ reply brief in support of class certification was filed on September 27, 2011. This issue is fully briefed and awaits district court determination. Boeing’s motions for summary judgment based on ERISA’s statute of repose and for summary judgment on the merits were both filed on December 21, 2011. The Company cannot reasonably estimate the range of loss, if any, that may result from this matter given the current procedural status of the litigation.

BSSI/ICO Litigation

On August 16, 2004, our wholly owned subsidiary, Boeing Satellite Systems International, Inc. (BSSI) filed a complaint for declaratory relief against ICO Global Communications (Operations), Ltd. (ICO) in Los Angeles County Superior Court seeking a declaration that ICO’s prior termination of two contracts for convenience extinguished all claims between the parties. On September 16, 2004, ICO filed a cross-complaint alleging breach of contract, economic duress, fraud, unfair competition, and other claims. ICO added The Boeing Company as a defendant in October 2005 to some of these claims and for interference with contract and misappropriation of trade secrets. On January 13, 2006, BSSI filed a cross-complaint against ICO, ICO Global Communications (Holdings) Limited (ICO Holdings), ICO’s parent, and Eagle River Investments, LLC, parent of both ICO and ICO Holdings, alleging fraud and other claims. The trial commenced on June 19, 2008, with ICO seeking to recover approximately $2,000 in damages, including all monies paid to BSSI and Boeing Launch Services, plus punitive damages and other unspecified damages and relief.

102

On October 21, 2008, the jury returned a verdict awarding ICO compensatory damages of $371 plus interest, based upon findings of contract breach, fraud and interference with contract. On October 31, 2008, the jury awarded ICO punitive damages of $236. On January 2, 2009, the court entered judgment for ICO in the amount of $631 which included $24 in prejudgment interest.

On February 26, 2009 the trial court granted in part and denied in part post-trial motions we filed seeking to set aside the verdict. As a result, on March 3, 2009, the court entered an amended judgment for ICO in the amount of $604, which included $371 in compensatory damages, $207 in punitive damages and $26 in prejudgment interest. Post-judgment interest will accrue on the judgment at the rate of 10% per year (simple interest) from January 2, 2009. As of December 31, 2011, the amount of post-judgment interest totaled $181.

We filed a notice of appeal and ICO filed a notice of cross-appeal in March 2009. We believe that we have substantial arguments on appeal, which we are pursuing vigorously. Oral argument took place on January 25, 2012, and a decision could be issued during the first quarter of 2012. Following this decision, either of the parties may seek discretionary review in the California Supreme Court.

BSSI/Telesat Canada

On November 9, 2006, Telesat Canada (Telesat) and a group of its insurers served BSSI with an arbitration demand alleging breach of contract, gross negligence and willful misconduct in connection with the constructive total loss of Anik F1, a model 702 satellite manufactured by BSSI. Telesat and its insurers initially sought over $385 in damages and $10 in lost profits, but revised their total demand to $263. BSSI has asserted a counterclaim against Telesat for $13.1 in unpaid performance incentive payments plus late charges. BSSI also asserted a $180 contingent counterclaim on the theory that any ultimate award to reimburse the insurers for their payments to Telesat could only result from Telesat’s breach of its contractual obligation to obtain a full waiver of subrogation rights barring recourse against BSSI. We believe that the claims asserted by Telesat and its insurers lack merit, but we have notified our insurance carriers of the demand. The arbitration was stayed pending an application by Telesat to the Ontario Superior Court on a preliminary issue. On July 16, 2010, the court denied Telesat’s request to exclude certain evidence, but granted its alternative request to remove the Chairperson from the arbitration panel. A new Chairperson was appointed on August 19, 2010, and the stay has been lifted. The arbitration hearing is currently scheduled for November 12, 2012.

On April 26, 2007, a group of our insurers filed a declaratory judgment action in the Circuit Court of Cook County, Illinois asserting certain defenses to coverage and requesting a declaration of their obligation under our insurance and reinsurance policies relating to the Telesat Anik F1 arbitration. On June 12, 2008, the court granted the insurers’ motion for summary judgment, concluding that our insurance policy excluded the kinds of losses alleged by Telesat. On January 16, 2009, the court granted Boeing’s motion for reconsideration, ruling in favor of Boeing to require the insurers to provide insurance coverage to defend the claim. The case has been stayed pending completion of the underlying arbitration.

Civil Securities Litigation

On November 13, 2009, plaintiff shareholders filed a putative securities fraud class action against The Boeing Company and two of our senior executives in federal district court in Chicago. This lawsuit arose from our June 2009 announcement that the first flight of the 787 Dreamliner would be postponed due to a need to reinforce an area within the side-of-body section of the aircraft. Plaintiffs contended that we were aware before June 2009 that the first flight could not take place as scheduled due to issues with the side-of-body section of the aircraft, and that our determination not to announce this

103

delay earlier resulted in an artificial inflation of our stock price for a multi-week period in May and June 2009. On March 7, 2011, the Court dismissed the complaint with prejudice. On April 4, 2011, plaintiffs filed a motion for reconsideration.

In addition, plaintiff shareholders have filed three similar shareholder derivative lawsuits concerning the flight schedule for the 787 Dreamliner that closely track the allegations in the putative class action lawsuit. Two of the suits were filed in Illinois state court and have been consolidated. The remaining derivative suit was filed in federal district court in Chicago. No briefing or discovery has yet taken place in any of these lawsuits. We believe the allegations in all of these cases are without merit, and we intend to contest the cases vigorously. The Company cannot reasonably estimate the range of loss, if any, that may result from this matter given the current procedural status of the litigation.

For segment reporting purposes, we record Commercial Airplanes segment revenues and cost of sales for airplanes transferred to other segments. Such transfers may include airplanes accounted for as operating leases and considered transferred to the BCC segment and airplanes transferred to the BDS segment for further modification prior to delivery to the customer. The revenues and cost of sales for these transfers are eliminated in the Unallocated items and eliminations caption. For segment reporting purposes, we record BDS revenues and cost of sales for the modification performed on airplanes received from Commercial Airplanes when the airplane is delivered to the customer or at the attainment of performance milestones.

Intersegment revenues, eliminated in Unallocated items and eliminations, are shown in the following table.

Years ended December 31,	2011		2010		2009

Unallocated Items and Eliminations

Unallocated items and eliminations includes costs not attributable to business segments as well as intercompany profit eliminations. We generally allocate costs to business segments based on the U.S. federal cost accounting standards. Unallocated pension and other postretirement expense which represents the difference between costs recognized under Generally Accepted Accounting Principles in the United States of America in the consolidated financial statements and federal cost accounting standards required to be utilized by certain business segments for U.S. government contracting purposes.

The most significant items not allocated to segments are shown in the following table.

Years ended December 31,	2011			2010			2009
Share-based plans	$	(83	)	$	(136	)	$	(189	)

Eliminations and other		(276	)		(428	)		(211	)
Total	$	(988	)	$	(735	)	$	(594	)

Unallocated assets primarily consist of cash and investments, net deferred tax assets, capitalized interest and assets held by SSG as well as intercompany eliminations. Unallocated liabilities include various accrued employee compensation and benefit liabilities, including accrued retiree health care, net deferred tax liabilities and income taxes payable. Debt securities and notes payable are not allocated to other business segments except for the portion related to BCC.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

The Boeing Company

Chicago, Illinois

We have audited the accompanying consolidated statements of financial position of The Boeing Company and subsidiaries (the “Company”) as of December 31, 2011 and 2010, and the related consolidated statements of operations, equity, and cash flows for each of the three years in the period ended December 31, 2011. Our audits also included the financial statement schedule listed in the Index at Item 15(a) 2. The financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on the financial statements and financial statement schedule based on our audits.

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

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of The Boeing Company and subsidiaries as of December 31, 2011 and 2010, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2011, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company’s internal control over financial reporting as of December 31, 2011, based on the criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 9, 2012 expressed an unqualified opinion on the Company’s internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

The Boeing Company

Chicago, Illinois

We have audited the internal control over financial reporting of The Boeing Company and subsidiaries (the “Company”) as of December 31, 2011, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

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

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

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2011, based on the criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements and financial statement schedule as of and for the year ended December 31, 2011 of the Company and our report dated February 9, 2012 expressed an unqualified opinion on those financial statements and financial statement schedule.

(b) Management’s Report on Internal Control Over Financial Reporting.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f). Our management conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation under the framework in Internal Control – Integrated Framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2011.

Our internal control over financial reporting as of December 31, 2011, has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report which is included in Item 8 of this report and is incorporated by reference herein.

Share-Based Compensation And Other Compensation Arrangements

Note 16 – Share-Based Compensation and Other Compensation Arrangements

Share-Based Compensation

Our 2003 Incentive Stock Plan, as amended and restated effective February 21, 2011, permits awards of incentive stock options, nonqualified stock options, restricted stock, stock units, performance shares, performance units and other incentives to our employees, officers, consultants and independent contractors. The aggregate number of shares of our stock available for issuance under the amended plan will not exceed 80,000,000 and no more than an aggregate of 16,000,000 shares are available for issuance as restricted stock awards.

Shares issued as a result of stock option exercises or conversion of stock unit awards will be funded out of treasury shares, except to the extent there are insufficient treasury shares, in which case new shares will be issued. We believe we currently have adequate treasury shares to meet any requirements to issue shares during 2012.

Share-based plans expense is primarily included in General and administrative expense since it is incentive compensation issued primarily to our executives. The share-based plans expense and related income tax benefit follow:

Years ended December 31,	2011		2010		2009
Stock options	$	88	$	96	$	111
Restricted stock units and other awards		98		83		56
ShareValue Trust				36		71
Share-based plans expense	$	186	$	215	$	238
Income tax benefit	$	73	$	83	$	89

Stock Options

In February 2011, 2010 and 2009, we granted to our executives 5,426,910, 5,932,806 and 7,423,242 options, respectively. The options have been granted with an exercise price equal to the fair market value of our stock on the date of grant and expire ten years after the date of grant. The stock options granted after 2005 vest over a period of three years, with 34% vesting after the first year, 33% vesting after the second year and the remaining 33% vesting after the third year. If an executive terminates employment for any reason, the non-vested portion of the stock option will not vest and all rights to the non-vested portion will terminate completely.

Stock option activity for the year ended December 31, 2011 is as follows:

	Shares			Weighted Average Exercise Price Per Share		Weighted Average Remaining Contractual Life (Years)		Aggregate Intrinsic Value
Number of shares under option:
Outstanding at beginning of year		28,975,442		$	65.96
Granted		5,658,705			71.29
Exercised		(2,447,099	)		46.88
Forfeited		(665,482	)		61.11
Expired		(90,171	)		61.88
Outstanding at end of year		31,431,395		$	68.52		6.58	$	290
Exercisable at end of year		20,488,535		$	71.77		5.51	$	170

The total intrinsic value of options exercised was $67, $59 and $2 during the years ended December 31, 2011, 2010 and 2009, respectively. Cash received from options exercised for the years ended December 31, 2011, 2010 and 2009 was $114, $87 and $10 with a related tax benefit of $23, $20 and $1, respectively, derived from the compensation deductions resulting from these option exercises. At December 31, 2011, there was $89 of total unrecognized compensation cost related to the Stock Option plan which is expected to be recognized over a weighted average period of 1.8 years. The grant date fair value of stock options vested during the years ended December 31, 2011, 2010 and 2009 was $92, $103 and $114, respectively.

The fair values of options were estimated using the Black-Scholes option-pricing model with the following assumptions:

Grant Year	Grant Date		Expected Life		Expected Volatility			Dividend Yield			Risk Free Interest Rate			Weighted-Average Grant Date Fair Value Per Share
2011		2/22/2011		6 years		29.8	%		2.3	%		2.5	%	$	17.96
2010		2/22/2010		6 years		31.5	%		3.0	%		2.9	%	$	15.70
2009		2/23/2009		6 years		39.0	%		2.4	%		2.0	%	$	11.12

The expected volatility of the stock options is based on a combination of our historical stock volatility and the volatility levels implied on the grant date by actively traded option contracts on our common stock. We determined the expected term of the stock option grants to be six years, calculated using the "simplified" method in accordance with the SEC Staff Accounting Bulletin 110. We use the "simplified" method since we changed the vesting terms, tax treatment and the recipients of our stock options beginning in 2006 such that we believe our historical data no longer provides a reasonable basis upon which to estimate expected term and we do not have enough option exercise data from our grants issued subsequent to 2006 to support our own estimate.

Restricted Stock Units

In February 2011, 2010 and 2009, we granted to our executives 1,364,440, 1,459,256 and 2,144,501 restricted stock units (RSUs) as part of our long-term incentive program with grant date fair values of $71.44, $63.83 and $35.57 per share, respectively. The RSUs vest on the third anniversary of the grant date. If an executive terminates employment because of retirement, involuntary layoff, disability, or death, the employee (or beneficiary) will immediately vest on a proration of stock units based on active employment during the three-year service period. In all other cases, the RSUs will not vest and all rights to the stock units will terminate completely.

In addition to RSUs awarded under our long-term incentive program, we grant RSUs to certain executives and employees to encourage retention or to reward various achievements. These RSUs are labeled other restricted stock units in the table below. The fair values of all RSUs are estimated using the average stock price on the date of grant. Stock units settle in common stock on a one-for-one basis and are not contingent upon stock price.

Stock unit activity for the year ended December 31, 2011 is as follows:

	Incentive Program Restricted Stock Units			Other Restricted Stock Units
Number of units:
Outstanding at beginning of year		3,425,800			1,701,951
Granted		1,421,906			197,526
Dividends		104,895			37,848
Forfeited		(152,608	)		(32,721	)
Distributed		(112,759	)		(410,436	)
Outstanding at end of year		4,687,234			1,494,168
Unrecognized compensation cost	$	98		$	23
Weighted average remaining contractual life (years)		1.8			1.9

Other Compensation Arrangements

Performance Awards

Performance Awards are cash units that pay out based on the achievement of long-term financial goals at the end of a three-year period. Each unit has an initial value of $100 dollars per unit. The amount payable at the end of the three-year performance period may be anywhere from $0 to $200 dollars per unit, depending on the Company's performance against plan for a three-year period. The Compensation Committee has the discretion to pay these awards in cash, stock, or a combination of both after the three-year performance period. Compensation expense, based on the estimated performance payout, is recognized ratably over the performance period.

During 2011, 2010 and 2009, we granted Performance Awards to our executives with the payout based on the achievement of financial goals for each three-year period following the grant date. The minimum payout amount is $0 and the maximum amount we could be required to pay out for the 2011, 2010 and 2009 Performance Awards is $265, $246 and $285, respectively. The 2009 grant is expected to be paid out in cash in March 2012.

Deferred Compensation

The Company has a deferred compensation plan which permits executives to defer receipt of a portion of their salary, bonus, and certain other incentive awards. Participants can diversify deferred compensation among 19 investment funds including a Boeing stock unit account.

Total expense related to deferred compensation was $59, $112 and $158 in 2011, 2010 and 2009, respectively. As of December 31, 2011 and 2010, the deferred compensation liability which is being marked to market was $1,093 and $1,149.

ShareValue Trust

The ShareValue Trust, established July 1, 1996, was a 14-year irrevocable trust that held shares of our common stock, received dividends, and distributed to employees the appreciation in value above a 3% per annum threshold rate of return at the end of each period. The trust was terminated effective July 1, 2010 with the 29,948,920 undistributed shares returned to the Company.

Fair Value Measurements [Abstract]

Fair Value Measurements

Note 20 – Fair Value Measurements

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. 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 non-observable inputs.

Total liabilities	$	(131	)			$	(131	)			$	(115	)			$	(115	)

Money market funds and available-for-sale equity securities are valued using a market approach based on the quoted market prices of identical instruments. Available-for-sale debt investments are primarily valued using an income approach based on benchmark yields, reported trades and broker/dealer quotes.

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 years ended December 31, and the carrying value and asset classification of the related assets as of December 31:

	2011					2010
	Carrying Value		Total Losses			Carrying Value		Total Losses
Operating lease equipment	$	72	$	(64	)	$	247	$	(143	)
Property, plant and equipment		3		(35	)				(4	)
Other assets, Acquired intangible assets, Cost investment		20		(11	)
Total	$	95	$	(110	)	$	247	$	(147	)

The operating lease equipment was valued using a market approach based on the fair value of the related aircraft. Property, plant and equipment, Other assets, and Acquired intangible assets were valued using an income approach based on the discounted cash flows associated with the underlying assets. The cost investment was valued using a market approach based on quoted market prices for related investments.

Fair Value Disclosures

The fair values and related carrying values of financial instruments that are not required to be remeasured at fair value on the Consolidated Statement of Financial Position at December 31 were as follows:

	2011						2010
	Carrying Amount			Fair Value			Carrying Amount			Fair Value
Assets
Accounts receivable, net	$	5,793		$	5,690		$	5,422		$	5,283
Notes receivable, net		792			836			480			501
Liabilities
Debt, excluding capital lease obligations		(12,136	)		(14,099	)		(12,234	)		(13,525	)
Accounts payable		(8,406	)		(8,396	)		(7,715	)		(7,704	)
Residual value and credit guarantees		(8	)		(9	)		(12	)		(11	)
Contingent repurchase commitments		(7	)		(4	)		(7	)		(84	)

The fair values of the Accounts receivable and Accounts payable are 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 using 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 is based on current market yields for our debt traded in the secondary market. The fair values of the residual value guarantees and contingent repurchase commitments are determined using a Black Futures Options formula and include such assumptions as the expected value of the aircraft on the settlement date, volatility of aircraft prices, time until settlement and the risk free discount rate. The fair value of the credit guarantees is estimated based on the expected cash flows of those commitments, given the creditor's probability of default, and discounted using the risk free rate. With regard to other financial instruments with off-balance sheet risk, it is not practicable to estimate the fair value of our indemnifications because the amount and timing of those arrangements are uncertain. Items not included in the above disclosures include cash and cash equivalents, restricted cash, time deposits and other deposits, commercial paper and long-term payables. The carrying values of those items, as reflected in the Consolidated Statements of Financial Position, approximate their fair value at December 31, 2011 and 2010.

Significant Group Concentrations Of Risk [Abstract]

Significant Group Concentrations Of Risk

Note 19 – Significant Group Concentrations of Risk

Credit Risk

Financial instruments involving potential credit risk are predominantly with commercial aircraft customers and the U.S. government. Of the $10,688 in gross accounts receivable and gross customer financing included in the Consolidated Statements of Financial Position as of December 31, 2011, $4,968 related predominantly to commercial aircraft customers ($660 of accounts receivable and $4,308 of customer financing) and $2,950 related to the U.S. government.

Of the $4,842 in gross customer financing, $2,817 related to customers we believe have less than investment-grade credit including American Airlines, United/Continental Airlines, and Hawaiian Airlines who were associated with 14%, 9% and 8%, respectively, of our financing portfolio. Financing for aircraft is collateralized by security in the related asset and in some instances security in other assets as well.

As of December 31, 2011, there was $15,866 of financing commitments related to aircraft on order including options and proposed as part of sales campaigns described in Note 12, of which $14,697 related to customers we believe have less than investment-grade credit.

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. Significant BDS fixed-price development contracts include Airborne Early Warning and Control (AEW&C), India P-8I, 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 also result in lower margins or a material charge for reach-forward losses in 2012.

Commercial Airplane Development Programs

The development and initial production of new commercial airplanes and new commercial airplane derivatives entail significant commitments to customers and suppliers as well as substantial investments in working capital, infrastructure and research and development. Performance issues or cost overruns on these programs, which currently include the 787 and 747-8 could have a material impact on our consolidated results and financial position in 2012.

Other Risk

Legal Proceedings [Abstract]

Legal Proceedings

Note 21 – Legal Proceedings

Various legal proceedings, claims and investigations related to products, contracts and other matters are pending against us. Potentially material contingencies are discussed below.

We are subject to various U.S. government investigations, from which civil, criminal or administrative proceedings could result or have resulted. 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 government disputes and investigations will not have a material effect on our financial position, results of operations, or cash flows, except as set forth below. 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 have disclosed 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.

A-12 Litigation

In 1991, the Department of the Navy (the Navy) notified McDonnell Douglas Corporation (now merged into The Boeing Company) and General Dynamics Corporation (together, the Team) that it was terminating for default the Team's contract for development and initial production of the A-12 aircraft.

The Team had full responsibility for performance of the contract and both contractors are jointly and severally liable for any potential liabilities resulting from the termination. The Team filed a legal action to contest the Navy's default termination, to assert its rights to convert the termination to one for "the convenience of the government," and to obtain payment for work done and costs incurred on the A-12 contract but not paid to date. As of December 31, 2011, inventories included approximately $586 of recorded costs on the A-12 contract, against which we have established a loss provision of $350. The amount of the provision, which was established in 1990, was based on McDonnell Douglas Corporation's belief, supported by an opinion of outside counsel, that the termination for default would be converted to a termination for convenience, and that the best estimate of possible loss on termination for convenience was $350.

On August 31, 2001, the U.S. Court of Federal Claims issued a decision after trial upholding the government's default termination of the A-12 contract. In 2003, the Court of Appeals for the Federal Circuit, finding that the trial court had applied the wrong legal standard, vacated the trial court's 2001 decision and ordered the case sent back to the trial court for further proceedings. On May 3, 2007, the U.S. Court of Federal Claims issued a decision upholding the government's default termination of the A-12 contract. We filed a Notice of Appeal on May 4, 2007 with the Court of Appeals for the Federal Circuit. On June 2, 2009, the Court of Appeals rendered an opinion affirming the trial court's 2007 decision sustaining the government's default termination. On May 23, 2011, the U.S. Supreme Court vacated the decision of the Court of Appeals upholding the default termination, and remanded the case to the Court of Appeals. On July 7, 2011, the Court of Appeals remanded the case to the trial court for additional factual determinations. On December 29, 2009, the Navy sent letters to the Team requesting payment of $1,352 in unliquidated progress payments, plus applicable interest. On November 15, 2011, the Navy sent a letter confirming that it would not pursue payment from the Team pending all trial court and appellate proceedings adjudicating the issues remanded by the Supreme Court.

We believe that the termination for default is contrary to law and fact and that the loss provision established by McDonnell Douglas Corporation in 1990, which was supported by an opinion from outside counsel, continues to provide adequately for the reasonably possible reduction in value of A-12 net contracts in process as of December 31, 2011. Final resolution of the A-12 litigation will depend on the outcome of further proceedings or possible negotiations with the U.S. government. If after all legal proceedings are concluded, the court determines, contrary to our belief, that a termination for default was appropriate, we could incur an additional loss of up to $275, consisting principally of $236 of remaining inventory costs. If the courts further hold that a money judgment should be entered against the Team, we could be required to pay the U.S. government up to one-half of the unliquidated progress payments of $1,350 plus statutory interest from February 1991 (currently totaling up to $1,565). In that event, our loss would total approximately $1,728 in pre-tax charges. Should, however, the March 31, 1998 judgment of the U.S. Court of Federal Claims in favor of the Team be reinstated, we could be entitled to receive payment of approximately $1,177, including interest from June 26, 1991.

Employment, Labor and Benefits Litigation

We have been named as a defendant in two pending class action lawsuits filed in the U.S. District Court for the District of Kansas, each related to the 2005 sale of our former Wichita facility to Spirit AeroSystems, Inc. (Spirit). The first action involves allegations that Spirit's hiring decisions following the sale were tainted by age discrimination, violated ERISA, violated our collective bargaining agreements, and constituted retaliation. The case was brought in 2006 as a class action on behalf of individuals not hired by Spirit. During the second quarter of 2010, the court granted summary judgment in favor of Boeing and Spirit on all class action claims. Following certain procedural motions, plaintiffs filed a notice of appeal to the Tenth Circuit Court of Appeals on August 10, 2011, and are seeking to stay all remaining individual claims in the district court pending resolution of the appeal. Plaintiffs' appellate brief was filed on November 14, 2011. Boeing's appellate brief was filed on January 20, 2012.

The second action, initiated in 2007, alleges collective bargaining agreement breaches and ERISA violations in connection with alleged failures to provide benefits to certain former employees of the Wichita facility. Written discovery closed by joint stipulation of the parties on June 6, 2011. Depositions concluded on August 18, 2011. Plaintiffs' partial motion for summary judgment was filed on December 9, 2011. Boeing's opposition and dispositive motions are due on February 10, 2012. Spirit has agreed to indemnify Boeing for any and all losses in the first action, with the exception of claims arising from employment actions prior to January 1, 2005. While Spirit has acknowledged a limited indemnification obligation in the second action, we believe that Spirit is obligated to indemnify Boeing for any and all losses in the second action.

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. The 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. During the first quarter of 2010, the Seventh Circuit Court of Appeals granted a stay of trial proceedings in the district court pending resolution of an appeal made by Boeing in 2008 to the case's class certification order. On January 21, 2011, the Seventh Circuit reversed the district court's class certification order and decertified the class. The Seventh Circuit remanded the case to the district court for further proceedings. On March 2, 2011, plaintiffs filed an amended motion for class certification and a supplemental motion on August 7, 2011. Boeing's opposition to class certification was filed on September 6, 2011. Plaintiffs' reply brief in support of class certification was filed on September 27, 2011. This issue is fully briefed and awaits district court determination. Boeing's motions for summary judgment based on ERISA's statute of repose and for summary judgment on the merits were both filed on December 21, 2011. The Company cannot reasonably estimate the range of loss, if any, that may result from this matter given the current procedural status of the litigation.

BSSI/ICO Litigation

On August 16, 2004, our wholly owned subsidiary, Boeing Satellite Systems International, Inc. (BSSI) filed a complaint for declaratory relief against ICO Global Communications (Operations), Ltd. (ICO) in Los Angeles County Superior Court seeking a declaration that ICO's prior termination of two contracts for convenience extinguished all claims between the parties. On September 16, 2004, ICO filed a cross-complaint alleging breach of contract, economic duress, fraud, unfair competition, and other claims. ICO added The Boeing Company as a defendant in October 2005 to some of these claims and for interference with contract and misappropriation of trade secrets. On January 13, 2006, BSSI filed a cross-complaint against ICO, ICO Global Communications (Holdings) Limited (ICO Holdings), ICO's parent, and Eagle River Investments, LLC, parent of both ICO and ICO Holdings, alleging fraud and other claims. The trial commenced on June 19, 2008, with ICO seeking to recover approximately $2,000 in damages, including all monies paid to BSSI and Boeing Launch Services, plus punitive damages and other unspecified damages and relief.

On October 21, 2008, the jury returned a verdict awarding ICO compensatory damages of $371 plus interest, based upon findings of contract breach, fraud and interference with contract. On October 31, 2008, the jury awarded ICO punitive damages of $236. On January 2, 2009, the court entered judgment for ICO in the amount of $631 which included $24 in prejudgment interest.

On February 26, 2009 the trial court granted in part and denied in part post-trial motions we filed seeking to set aside the verdict. As a result, on March 3, 2009, the court entered an amended judgment for ICO in the amount of $604, which included $371 in compensatory damages, $207 in punitive damages and $26 in prejudgment interest. Post-judgment interest will accrue on the judgment at the rate of 10% per year (simple interest) from January 2, 2009. As of December 31, 2011, the amount of post-judgment interest totaled $181.

We filed a notice of appeal and ICO filed a notice of cross-appeal in March 2009. We believe that we have substantial arguments on appeal, which we are pursuing vigorously. Oral argument took place on January 25, 2012, and a decision could be issued during the first quarter of 2012. Following this decision, either of the parties may seek discretionary review in the California Supreme Court.

BSSI/Telesat Canada

On November 9, 2006, Telesat Canada (Telesat) and a group of its insurers served BSSI with an arbitration demand alleging breach of contract, gross negligence and willful misconduct in connection with the constructive total loss of Anik F1, a model 702 satellite manufactured by BSSI. Telesat and its insurers initially sought over $385 in damages and $10 in lost profits, but revised their total demand to $263. BSSI has asserted a counterclaim against Telesat for $13.1 in unpaid performance incentive payments plus late charges. BSSI also asserted a $180 contingent counterclaim on the theory that any ultimate award to reimburse the insurers for their payments to Telesat could only result from Telesat's breach of its contractual obligation to obtain a full waiver of subrogation rights barring recourse against BSSI. We believe that the claims asserted by Telesat and its insurers lack merit, but we have notified our insurance carriers of the demand. The arbitration was stayed pending an application by Telesat to the Ontario Superior Court on a preliminary issue. On July 16, 2010, the court denied Telesat's request to exclude certain evidence, but granted its alternative request to remove the Chairperson from the arbitration panel. A new Chairperson was appointed on August 19, 2010, and the stay has been lifted. The arbitration hearing is currently scheduled for November 12, 2012.

On April 26, 2007, a group of our insurers filed a declaratory judgment action in the Circuit Court of Cook County, Illinois asserting certain defenses to coverage and requesting a declaration of their obligation under our insurance and reinsurance policies relating to the Telesat Anik F1 arbitration. On June 12, 2008, the court granted the insurers' motion for summary judgment, concluding that our insurance policy excluded the kinds of losses alleged by Telesat. On January 16, 2009, the court granted Boeing's motion for reconsideration, ruling in favor of Boeing to require the insurers to provide insurance coverage to defend the claim. The case has been stayed pending completion of the underlying arbitration.

Civil Securities Litigation

On November 13, 2009, plaintiff shareholders filed a putative securities fraud class action against The Boeing Company and two of our senior executives in federal district court in Chicago. This lawsuit arose from our June 2009 announcement that the first flight of the 787 Dreamliner would be postponed due to a need to reinforce an area within the side-of-body section of the aircraft. Plaintiffs contended that we were aware before June 2009 that the first flight could not take place as scheduled due to issues with the side-of-body section of the aircraft, and that our determination not to announce this delay earlier resulted in an artificial inflation of our stock price for a multi-week period in May and June 2009. On March 7, 2011, the Court dismissed the complaint with prejudice. On April 4, 2011, plaintiffs filed a motion for reconsideration.

In addition, plaintiff shareholders have filed three similar shareholder derivative lawsuits concerning the flight schedule for the 787 Dreamliner that closely track the allegations in the putative class action lawsuit. Two of the suits were filed in Illinois state court and have been consolidated. The remaining derivative suit was filed in federal district court in Chicago. No briefing or discovery has yet taken place in any of these lawsuits. We believe the allegations in all of these cases are without merit, and we intend to contest the cases vigorously. The Company cannot reasonably estimate the range of loss, if any, that may result from this matter given the current procedural status of the litigation.

Arrangements With Off-Balance Sheet Risk [Abstract]

Arrangements With Off-Balance Sheet Risk

Note 13 – 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 tables provide 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.

	Maximum Potential Payments				Estimated Proceeds from Collateral/ Recourse				Carrying Amount of Liabilities
December 31,	2011		2010		2011		2010		2011		2010
Contingent repurchase commitments	$	3,290	$	3,782	$	3,290	$	3,759	$	7	$	7
Indemnifications to ULA:

Contract pricing		261		261						7		7
Other Delta contracts		137		83						8		16
Other indemnifications		212		232						51		82
Credit guarantees		17		71		12		63		2		6
Residual value guarantees		29		29		21		21		6		6

Contingent Repurchase Commitments We have entered into contingent repurchase commitments with certain customers in conjunction with signing definitive agreements for the sale of new aircraft. Under these commitments, we agreed to repurchase the Sale Aircraft at a specified price, generally 10 to 15 years after delivery of the Sale Aircraft. Our repurchase of the Sale Aircraft is contingent upon a future, mutually acceptable agreement for the sale of additional new aircraft, and the subsequent exercise by the customer of its right to sell the Sale Aircraft to us. 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 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 $1,211 of inventory that was contributed by us. ULA has made advance payments of $720 to us and we have recorded revenues and cost of sales of $483 under the inventory supply agreement through December 31, 2011. ULA is continuing to assess the future of the Delta II program beyond what is currently on contract. In the event ULA is unable to sell additional Delta II inventory, our earnings could be reduced by up to $58.

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. The DCMA has not yet issued a final decision related to the recoverability of the $114. 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. ULA has until June 2012 to file a suit with the Court of Federal Claims for collection of deferred support costs. 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.

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 for a third satellite mission. During the third quarter of 2010, ULA submitted 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. In March 2011, ULA filed a notice of appeal before the ASBCA, seeking to re-price the third mission. A hearing before the ASBCA has been scheduled for May 6, 2013. If ULA is unsuccessful in obtaining additional pricing, we may be responsible for a portion of the shortfall and may record up to $279 in pre-tax losses associated with the three missions, representing up to $261 for the indemnification payment and up to $18 for our portion of additional contract losses incurred by ULA.

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 nine years.

Residual Value Guarantees We have issued various residual value guarantees principally to facilitate the sale and financing of certain commercial aircraft. Under these guarantees, we are obligated to make payments to the guaranteed party if the related aircraft or equipment fair values fall below a specified amount at a future time. These obligations are collateralized principally by the underlying commercial aircraft and expire within the next seven years.

Other Indemnifications As part of the 2004 sale agreement with General Electric Capital Corporation related to the sale of Boeing Capital Corporation's (BCC) Commercial Financial Services business, BCC is involved in a loss sharing arrangement for losses on transferred portfolio assets, such as asset sales, provisions for loss or asset impairment charges offset by gains from asset sales. At December 31, 2011 and 2010, our maximum future cash exposure to losses associated with the loss sharing arrangement was $212 and $232 and our accrued liability under the loss sharing arrangement was $51 and $82.

In conjunction with our sales of the Electron Dynamic Devices, Inc. and Rocketdyne Propulsion and Power businesses and the sale of our Commercial Airplanes facilities in Wichita, Kansas and Tulsa and McAlester, Oklahoma in 2005, we agreed to indemnify, for an indefinite period, the buyers for costs relating to pre-closing environmental contamination and certain other items. As it is impossible to assess whether there will be damages in the future or the amounts thereof (if any), we cannot estimate the maximum potential amount of future payments under these indemnities. Therefore, no liability has been recorded. There have been no claims submitted to date.

Industrial Revenue Bonds

Industrial Revenue Bonds (IRBs) issued by the City of Wichita were used to finance the purchase and/or construction of real and personal property at our Wichita site. Tax benefits associated with IRBs include a ten-year property tax abatement and a sales tax exemption from the Kansas Department of Revenue. We record the property on our Consolidated Statements of Financial Position, along with a capital lease obligation to repay the proceeds of the IRB. We have also purchased the IRBs and therefore are the bondholders as well as the borrower/lessee of the property purchased with the IRB proceeds.

The capital lease obligation and IRB asset are recorded net in the Consolidated Statements of Financial Position. As of December 31, 2011 and 2010, the net assets associated with the City of Wichita IRBs were $783 and $822.

Postretirement Plans [Abstract]

Postretirement Plans

Note 15 – Postretirement Plans

The majority of our employees are covered by defined benefit pension plans. All nonunion and some union employees hired after December 31, 2008 are not covered by defined benefit plans. We fund our major pension plans through trusts. Pension assets are placed in trust solely for the benefit of the plans' participants, and are structured to maintain liquidity that is sufficient to pay benefit obligations as well as to keep pace over the long-term with the growth of obligations for future benefit payments.

We also have other postretirement benefits (OPB) other than pensions which consist principally of health care coverage for eligible retirees and qualifying dependents, and to a lesser extent, life insurance to certain groups of retirees. Retiree health care is provided principally until age 65 for approximately half those retirees who are eligible for health care coverage. Certain employee groups, including employees covered by most United Auto Workers bargaining agreements, are provided lifetime health care coverage.

The funded status of the plans is measured as the difference between the plan assets at fair value and the projected benefit obligation (PBO). We have recognized the aggregate of all overfunded plans in Pension plan assets, net, and the aggregate of all underfunded plans in either Accrued retiree health care or Accrued pension plan liability, net. The portion of the amount by which the actuarial present value of benefits included in the PBO exceeds the fair value of plan assets, payable in the next 12 months, is reflected in Accrued liabilities.

The components of net periodic benefit cost are as follows:

	Pension									Other Postretirement Plans
Years ended December 31,	2011			2010			2009			2011			2010			2009
Service cost	$	1,406		$	1,176		$	1,090		$	221		$	121		$	132
Interest cost		3,116			3,002			2,964			484			404			466
Expected return on plan assets		(3,741	)		(3,850	)		(3,738	)		(6	)		(6	)		(5	)
Amortization of prior service costs		244			248			242			(96	)		(78	)		(90	)
Recognized net actuarial loss		1,254			777			650			178			56			92
Settlement/curtailment/transfer loss		64			14			13			3
Net periodic benefit cost	$	2,343		$	1,367		$	1,221		$	784		$	497		$	595
Net periodic benefit cost included in Earnings from operations	$	1,648		$	1,101		$	879		$	692		$	480		$	615

During the quarter ended September 30, 2011, we determined the accumulated benefit obligation (ABO) for certain other postretirement benefit plans was understated. As a result, we recognized an additional $294 of postretirement benefit obligations at September 30, 2011. This increased net periodic benefit cost during 2011 by $184, which includes service cost of $73, interest cost of $68 and recognized net actuarial loss of $43. Had the understatement been recorded at December 31, 2010, the postretirement benefit obligation would have increased by $274 from $8,546 to $8,820. Management believes that these understatements were not material to the current period or prior periods.

Under our accounting policy, a portion of net periodic benefit cost is allocated to production as inventoried costs. Of the $184 increase in net periodic benefit cost described above, the associated cost included in Earnings from operations was $161 for the quarter ended September 30, 2011, with the remaining cost of $23 classified as inventory.

The following tables show changes in the benefit obligation, plan assets and funded status of both pensions and OPB for the years ended December 31, 2011 and 2010. Benefit obligation balances presented below reflect the PBO for our pension plans, and accumulated postretirement benefit obligations (APBO) for our OPB plans.

The estimated amount that will be amortized from Accumulated other comprehensive loss into net periodic benefit cost during the year ended December 31, 2012 is as follows:

	Pensions		Other Postretirement Benefits
Recognized net actuarial loss	$	1,935	$	123
Amortization of prior service costs/(credits)		226		(197	)
Total	$	2,161	$	(74	)

The ABO for all pension plans was $61,902 and $53,513 at December 31, 2011 and 2010. Key information for our plans with ABO in excess of plan assets as of December 31 is as follows:

	2011		2010
Projected benefit obligation	$	67,418	$	58,772
Accumulated benefit obligation		61,675		53,202
Fair value of plan assets		50,820		48,926

The Patient Protection and Affordable Care Act, as modified by the Health Care and Education Reconciliation Act of 2010 increased our APBO by $300 at December 31, 2010. This includes the impact of the excise tax on high cost health plans scheduled to become payable beginning in 2018. This increase is recognized as an actuarial loss and is amortized over the expected future service of current employees.

Assumptions

The following assumptions, which are the weighted average for all plans, are used to calculate the benefit obligation at December 31 of each year and the net periodic benefit cost for the subsequent year.

December 31,	2011			2010			2009
Discount rate:
Pension		4.40	%		5.30	%		5.80	%
Other postretirement benefits		4.00	%		4.90	%		5.40	%
Expected return on plan assets		7.75	%		7.75	%		8.00	%
Rate of compensation increase		3.90	%		5.20	%		5.50	%

The discount rate for each plan is determined based on the plans' expected future benefit payments using a yield curve developed from high quality bonds that are rated as Aa or better by Moody's as of the measurement date. The yield curve is fitted to yields developed from bonds at various maturity points. Bonds with the ten percent highest and the ten percent lowest yields are omitted. A portfolio of about 400 bonds is used to construct the yield curve. Since corporate bond yields are generally not available at maturities beyond 30 years, it is assumed that spot rates will remain level beyond that 30-year point. The present value of each plan's benefits is calculated by applying the spot/discount rates to projected benefit cash flows. All bonds are U.S. issues, with a minimum outstanding of $50.

The pension fund's expected return on plan assets assumption is derived from a review of actual historical returns achieved by the pension trust and anticipated future long-term performance of individual asset classes. While consideration is given to recent trust performance and historical returns, the assumption represents a long-term, prospective return. The expected return on plan assets component of the net periodic benefit cost for the upcoming plan year is determined based on the expected return on plan assets assumption and the market-related value of plan assets (MRVA). Since our adoption of the accounting standard for pensions in 1987, we have determined the MRVA based on a five-year moving average of plan assets. As of December 31, 2011, the MRVA is approximately $790 less than the fair market value of assets.

Assumed health care cost trend rates were as follows:

December 31,	2011			2010			2009
Health care cost trend rate assumed next year		7.50	%		7.50	%		7.00	%
Ultimate trend rate		5.00	%		5.00	%		5.00	%
Year that trend reached ultimate rate		2018			2018			2014

Assumed health care cost trend rates have a significant effect on the amounts reported for the health care plans. To determine the health care cost trend rates we look at a combination of information including ongoing claims cost monitoring, annual statistical analyses of claims data, reconciliation of forecast claims against actual claims, review of trend assumptions of other plan sponsors and national health trends, and adjustments for plan design changes, workforce changes, and changes in plan participant behavior. A one-percentage-point change in assumed health care cost trend rates would have the following effect:

	Increase		Decrease
Effect on total of service and interest cost	$	63	$	(54	)
Effect on postretirement benefit obligation		642		(572	)

Plan Assets

Investment Strategy The overall objective of our pension assets is to earn a rate of return over time to satisfy the benefit obligations of the pension plans and to maintain sufficient liquidity to pay benefits and address other cash requirements of the pension fund. Specific investment objectives for our long-term investment strategy include reducing the volatility of pension assets relative to pension liabilities, achieving a competitive, total investment return, achieving diversification between and within asset classes and managing other risks. Investment objectives for each asset class are determined based on specific risks and investment opportunities identified.

We periodically update our long-term, strategic asset allocations. We use various analytics to determine the optimal asset mix and consider plan liability characteristics, liquidity characteristics, funding requirements, expected rates of return and the distribution of returns. We identify investment benchmarks for the asset classes in the strategic asset allocation that are market-based and investable where possible.

Actual allocations to each asset class vary from target allocations due to periodic investment strategy changes, market value fluctuations, the length of time it takes to fully implement investment allocation positions (such as private equity and real estate), and the timing of benefit payments and contributions. Short term investments and exchange-traded derivatives are used to rebalance the actual asset allocation to the target asset allocation. The asset allocation is monitored and rebalanced on a monthly basis.

The actual allocations for the pension assets at December 31 and target allocations by asset class, are as follows:

	Percentage of Plan Assets						Target Allocations
Asset Class	2011			2010			2011			2010
Fixed income		53	%		49	%		49	%		45	%
Global equity		26			33			30			28
Private equity		6			5			6			6
Real estate and real assets		6			5			6			10
Global strategies		4			4			4			5
Hedge funds		5			4			5			6
Total		100	%		100	%		100	%		100	%

Fixed income securities are invested broadly and primarily in long duration instruments. Global equity securities are invested broadly in U.S. and non-U.S. companies which are in various industries and countries and through a range of market capitalizations.

Real estate and real assets include global private investments and publicly traded investments (such as REITs in the case of real estate). Real estate includes but is not limited to investments in office, retail, apartment and industrial properties. Real assets include but are not limited to investments in natural resources (such as energy, farmland and timber), commodities and infrastructure. Private equity investment vehicles are primarily limited partnerships (LPs) and fund-of-funds that mainly invest in U.S. and non-U.S. leveraged buyout, venture capital and special situation strategies.

Global strategies seek to capitalize on inefficiencies identified across different asset classes or markets, primarily using long-short positions in derivatives and physical securities. Hedge fund strategy types include, but are not limited to event driven, relative value, long-short and market neutral. A well-diversified number of hedge funds are held.

Investment managers are retained for explicit investment roles specified by contractual investment guidelines. Certain investment managers are authorized to invest in derivatives, such as equity or bond futures, swaps, options and currency futures or forwards. Derivatives are used to achieve the desired market exposure of a security or an index, transfer value-added performance between asset classes, achieve the desired currency exposure, adjust portfolio duration or rebalance the total portfolio to the target asset allocation.

As a percentage of total plan assets, derivative net notional amounts were 3.9% and 9.8% for fixed income, including to-be-announced mortgage-backed securities and treasury forwards, and 3.5% and negative 0.2% for global equity and currency overlay at December 31, 2011 and 2010.

In November 2009, the Company elected to contribute $1,500 of our common stock to the pension fund. An independent fiduciary was retained to manage and liquidate the stock over time at its discretion. The liquidation of the common stock holdings was completed during 2011.

Risk Management In managing the plan assets, we review and manage risk associated with funded status risk, interest rate risk, market risk, counterparty risk, liquidity risk and operational risk. Liability management and asset class diversification are central to our risk management approach and are integral to the overall investment strategy. Further, asset classes are constructed to achieve diversification by investment strategy, by investment manager, by industry or sector and by holding. Investment manager guidelines for publicly traded assets are specified and are monitored regularly through the custodian. Credit parameters for counterparties have been established for managers permitted to trade over-the-counter derivatives.

Fair Value Measurements The following table presents our plan assets using the fair value hierarchy as of December 31, 2011 and 2010. 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 non-observable inputs.

Fixed income securities are primarily valued using a market approach with inputs that include broker quotes, benchmark yields, base spreads and reported trades.

Cash equivalents and other short-term investments, which are used to pay benefits, are primarily held in registered money market funds which are valued using a market approach based on the quoted market prices of identical instruments. Other cash equivalent and short-term investments are valued daily by the fund using a market approach with inputs that include quoted market prices for similar instruments.

Common and preferred stock equity securities are primarily valued using a market approach based on the quoted market prices of identical instruments. Common/collective/pooled funds are typically common or collective trusts valued at their net asset values (NAVs) that are calculated by the investment manager or sponsor of the fund and have daily or monthly liquidity. Active currency managers, through an overlay program, invest in a broad set of currency derivatives. Derivatives leveled in the table above are over-the-counter and are primarily valued using an income approach with inputs that include benchmark yields, swap curves, cash flow analysis, rating agency data and interdealer broker rates. Exchange-traded derivative positions are reported in accordance with changes in daily variation margin which is settled daily and therefore reflected in the payables and receivables portion of the table.

Private equity valuations are reported by the fund manager and are based on the valuation of the underlying investments, which include inputs such as cost, operating results, discounted future cash flows and market based comparable data.

Real estate and real asset fund values are primarily reported by the fund manager and are based on valuation of the underlying investments, which include inputs such as cost, discounted future cash flows, independent appraisals and market based comparable data. Publically traded REITs and infrastructure stocks are valued using a market approach based on quoted market prices of identical instruments. Exchange-traded commodities futures positions are reported in accordance with changes in daily variation margin which is settled daily and therefore reflected in the payables and receivables portion of the table.

Global strategies are primarily limited liability company (LLC) or mutual fund structures. The LLCs are primarily valued using a market approach based on NAVs calculated by the fund and have monthly liquidity. Global strategies mutual funds are valued using a market approach based on the quoted market prices of identical instruments.

Hedge funds consist of fund-of-fund LLC or commingled fund structures and direct hedge funds. The LLCs are primarily valued using a market approach based on NAVs calculated by the fund and are not publicly available. Liquidity for the LLCs is monthly and is subject to liquidity of the underlying hedge funds. The commingled fund NAV is calculated by the manager on a daily basis and has monthly liquidity. Direct hedge funds are primarily valued by each fund's third party administrator based on valuation of the underlying securities and instruments and primarily applying a market or income valuation methodology depending on the specific type of security or instrument, equity, fixed income, currency or derivative, held. Direct hedge fund NAVs based on valuation of the underlying holdings are not publicly available and have monthly liquidity.

Some of our assets, primarily our private equity, real estate and real assets, hedge funds and global strategies, do not have readily determinable market values given the specific investment structures involved and the nature of the underlying investments. For the December 31, 2011 and 2010 plan asset reporting, publicly traded asset pricing was used where possible. For assets without readily determinable values, estimates were derived from investment manager discussions focusing on underlying fundamentals and significant events. For those investments reported on a one-quarter lagged basis (primarily LPs) we use net asset values, adjusted for subsequent cash flows and significant events.

The following tables present a reconciliation of Level 3 assets held during the year ended December 31, 2011 and 2010. Transfers into and out of Level 3 are treated as beginning of year values.

	January 1, 2011 Balance		Net Realized and Unrealized Gains/(Losses)			Net Purchases, Issuances and Settlements			Net Transfers Into/(Out of) Level 3		December 31, 2011 Balance

OPB Plan Assets The majority of OPB plan assets are invested in a balanced index fund which is comprised of approximately 60% equities and 40% debt securities. The index fund is valued using a market approach based on the quoted market price of an identical instrument (Level 1). The expected rate of return on these assets does not have a material effect on the net periodic benefit cost.

Cash Flows

Contributions Required pension contributions under the Employee Retirement Income Security Act (ERISA) as well as rules governing funding of our non-U.S. pension plans, are expected to be minimal in 2012. We expect to make discretionary contributions to our plans of approximately $1,500 in 2012. We expect to contribute approximately $15 to our OPB plans in 2012.

Estimated Future Benefit Payments The table below reflects the total pension benefits expected to be paid from the plans or from our assets, including both our share of the benefit cost and the participants' share of the cost, which is funded by participant contributions. OPB payments reflect our portion only.

Year(s)	2012			2013			2014			2015			2016			2017–2021
Pensions	$	2,829		$	2,979		$	3,140		$	3,313		$	3,448		$	19,501

Net other postretirement benefits	$	477		$	498		$	522		$	546		$	575		$	3,225

Termination Provisions

Certain of the pension plans provide that, in the event there is a change in control of the Company which is not approved by the Board of Directors and the plans are terminated within five years thereafter, the assets in the plan first will be used to provide the level of retirement benefits required by ERISA, and then any surplus will be used to fund a trust to continue present and future payments under the postretirement medical and life insurance benefits in our group insurance benefit programs.

We have an agreement with the U.S. government with respect to certain pension plans. Under the agreement, should we terminate any of the plans under conditions in which the plan's assets exceed that plan's obligations, the U.S. government will be entitled to a fair allocation of any of the plan's assets based on plan contributions that were reimbursed under U.S. government contracts.

Defined Contribution Plans

We provide certain defined contribution plans to all eligible employees. The principal plans are the Company-sponsored 401(k) plans. The expense for these defined contribution plans was $658, $614 and $591 in 2011, 2010 and 2009, respectively.

Customer Financing [Abstract]

Customer Financing

Note 8 – Customer Financing

Customer financing at December 31 consisted of the following:

	2011			2010
Financing receivables:
Investment in sales-type/finance leases	$	2,037		$	2,272
Notes		814			480
Operating lease equipment, at cost, less accumulated depreciation of $765 and $847		1,991			2,281
Gross customer financing		4,842			5,033
Less allowance for losses on receivables		(70	)		(353	)
Total	$	4,772		$	4,680

The components of investment in sales-type/finance leases at December 31 were as follows:

	2011			2010
Minimum lease payments receivable	$	2,272		$	2,879
Estimated residual value of leased assets		541			619
Unearned income		(776	)		(1,226	)
Total	$	2,037		$	2,272

Operating lease equipment primarily includes large commercial jet aircraft and regional jet aircraft. At December 31, 2011 and 2010, operating lease equipment included $521 and $583 of equipment available for sale or re-lease. At December 31, 2011 and 2010, we had firm lease commitments for $476 and $28 of this equipment.

When our Commercial Airplanes segment is unable to immediately sell used aircraft, it may place the aircraft under an operating lease. It may also provide customer financing with a note receivable. The carrying amount of the Commercial Airplanes segment used aircraft under operating leases and notes receivable included as a component of customer financing totaled $357 and $167 as of December 31, 2011 and 2010.

Financing receivable balances evaluated for impairment at December 31 were as follows:

	2011		2010
Individually evaluated for impairment	$	854	$	99
Collectively evaluated for impairment		1,997		2,653
Total financing receivables	$	2,851	$	2,752

Of the $854 and $99 of financing receivables individually evaluated for impairment as of December 31, 2011 and 2010, $485 and $0, were classified as impaired. We recorded no allowance for losses on these impaired receivables.

The average recorded investment in impaired financing receivables for the years ended December 31, 2011, 2010 and 2009, was $517, $88 and $162, respectively. Income recognition is generally suspended for financing receivables at the date full recovery of income and principal becomes not probable. Income is recognized when financing receivables become contractually current and performance is demonstrated by the customer. As of December 31, 2011, we had no interest income recognized on such receivables and $9 and $9 for the years ended December 31, 2010 and 2009, respectively.

The change in the allowance for losses on financing receivables for the years ended December 31, 2011, 2010 and 2009, consisted of the following:

	2011			2010			2009
Beginning balance – January 1	$	(353	)	$	(302	)	$	(269	)
Customer financing valuation benefit/(provision)		269			(51	)		(45	)
Reduction in customer financing assets		14						12
Ending balance – December 31	$	(70	)	$	(353	)	$	(302	)
Individually evaluated for impairment							$	(2	)
Collectively evaluated for impairment	$	(70	)	$	(353	)		(300	)

We assign internal credit ratings for all customers and determine the creditworthiness of each customer based upon public information and information obtained directly from our customers. We utilize these credit ratings as one of the factors in assessing the adequacy of our allowance for losses on receivables. Our rating categories are comparable to those used by the major credit rating agencies. The customer financing valuation benefit recorded in 2011 was primarily driven by changes in the internal credit rating categories assigned to our receivable balances from AirTran Holdings, LLC (AirTran).

The following table details our financing receivable balances at December 31, by the internal credit rating category which was used as a factor in determining our allowance for losses on receivables.

Rating categories	2011		2010
BBB	$	1,316
BB		67
B		103	$	207
CCC		512		2,432
D		653
Other		200		113
Total carrying value of financing receivables	$	2,851	$	2,752

At December 31, 2011, our allowance primarily related to receivables with ratings of BBB and CCC and we applied default rates that averaged 4% and 48% to exposure associated with those receivables. On May 2, 2011, Southwest Airlines Co. (Southwest) completed its acquisition of AirTran Holdings, Inc. and AirTran Holdings, Inc. became a wholly owned subsidiary of Southwest. AirTran became the successor to AirTran Holdings, Inc. As a result, we took into account Southwest's credit rating when we determined the allowance for losses on AirTran receivables during 2011. In the fourth quarter of 2011, we revised the contractual terms of our leases with AirTran in conjunction with receiving a full guarantee from Southwest which guaranteed AirTran's obligations to BCC. At December 31, 2011 and 2010, we assigned the internal rating categories of BBB and CCC to the receivables from AirTran for the purpose of assigning default rates discussed above. The improved rating in 2011 reduced the allowance for losses on receivables by $241 for the year ended December 31, 2011.

In the fourth quarter of 2011, American Airlines filed for Chapter 11 bankruptcy protection. We believe that our customer financing receivables from American Airlines of $653 are sufficiently collateralized such that we do not expect to incur losses related to those receivables as a result of the bankruptcy.

Declines in collateral values are also a significant driver of our allowance for losses. Generally, out-of-production aircraft have had greater percentages of collateral value declines than in-production aircraft. Our portfolio consists primarily of financing receivables for out-of-production aircraft.

As of December 31, 2011 and 2010, we had no material receivables that were greater than 30 days past due.

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 may be subject to reduced valuation with market decline. Our customer financing portfolio has a concentration of various model aircraft. Customer financing carrying values related to major aircraft concentrations at December 31 were as follows:

	2011		2010
717 Aircraft ($480 and $561 accounted for as operating leases)(1)	$	1,906	$	2,070
757 Aircraft ($451 and $629 accounted for as operating leases)(1)		631		720
737 Aircraft ($242 and $317 accounted for as operating leases)		394		366
767 Aircraft ($103 and $115 accounted for as operating leases)		307		372
MD-11 Aircraft ($321 and $327 accounted for as operating leases)(1)		321		327

⁽¹⁾  Out of production aircraft

Charges related to customer financing asset impairment for the years ended December 31 were as follows:

	2011			2010		2009
Boeing Capital Corporation	$	109		$	85	$	91
Other Boeing		(36	)		85		8
Total	$	73		$	170	$	99

Scheduled receipts on customer financing are as follows:

Year	2012		2013		2014		2015		2016		Beyond 2016
Principal payments on notes receivable	$	243	$	196	$	105	$	52	$	37	$	181
Sales-type/finance lease payments receivable		326		285		226		225		221		989
Operating lease equipment payments receivable		219		185		164		153		84		125

Customer financing assets leased under capital leases and subleased to others were not significant in 2011 and 2010.

The following table summarizes our accounts receivable under long-term contracts that were not billable or related to outstanding claims as of December 31:

	Unbillable				Claims
	2011		2010		2011		2010
Current	$	1,174	$	994	$	49	$	30
Expected to be collected after one year		498		507		209		194
Total	$	1,672	$	1,501	$	258	$	224

Under contract accounting unbillable receivables on long-term contracts arise when the sales or revenues based on performance attainment, though appropriately recognized, cannot be billed yet under terms of the contract as of the balance sheet date. Any adjustment for the credit quality of unbillable receivables, if required, would be recorded as a direct reduction of revenue. Factors considered in assessing the collectability of unbillable receivables include, but are not limited to, a customer's extended delinquency, requests for restructuring and filings for bankruptcy. Unbillable receivables related to commercial customers expected to be collected after one year were $192 and $213 at December 31, 2011 and 2010. Accounts receivable related to claims are items that we believe are earned, but are subject to uncertainty concerning their determination or ultimate realization. Accounts receivable, other than those described above, expected to be collected after one year are not material.

Earnings Per Share

Note 4 – Earnings Per Share

The weighted-average number of shares outstanding used to compute earnings per share are as follows:

(Shares in millions) Years ended December 31,	2011		2010		2009
Weighted average shares outstanding		744.1		735.0		705.9
Participating securities		2.5		3.1		3.7
Basic weighted average shares outstanding		746.6		738.1		709.6
Dilutive potential common shares		6.5		6.2		3.8
Diluted weighted average shares outstanding		753.1		744.3		713.4

Basic earnings per share is calculated by the sum of (1) net earnings less declared dividends and dividend equivalents related to share-based compensation divided by the basic weighted average shares outstanding and (2) declared dividends and dividend equivalents related to share-based compensation divided by the weighted average shares outstanding.

The weighted average number of shares outstanding, included in the table below, were excluded from the computation of diluted earnings per share because the average market price did not exceed the exercise/threshold price. However, these shares may be dilutive potential common shares in the future.

The components of earnings before income taxes were:

Non-U.S.		310		197		93
Total	$	5,393	$	4,507	$	1,731

Income tax expense/(benefit) consisted of the following:

Years ended December 31,	2011			2010			2009
Current tax expense
U.S. federal	$	(605	)	$	13		$	(132	)

Total deferred		1,916			1,240			314
Total income tax expense	$	1,382		$	1,196		$	396

Net income tax payments/(refunds) were $57, $360, and $(198) in 2011, 2010 and 2009, respectively.

Our effective income tax rate was 25.6%, 26.5%, and 22.9% for the years ended December 31, 2011, 2010 and 2009, respectively. Our 2011 effective tax rate was lower than 2010, primarily due to an income tax charge of $150 recorded during the first quarter of 2010 as a result of the Patient Protection and Affordable Care Act, as modified by the Health Care and Education Reconciliation Act of 2010. Our 2010 effective tax rate was higher than 2009, primarily because pre-tax book income in 2010 was higher than in 2009 and because of the income tax charge of $150 recorded during the first quarter of 2010. This was partially offset by a tax benefit of $371 recorded during the fourth quarter of 2010 as a result of settling the 1998-2003 federal audit. The following is a reconciliation of the U.S. federal statutory tax rate of 35% to our effective income tax rate:

Years ended December 31,	2011			2010			2009
U.S. federal statutory tax		35.0	%		35.0	%		35.0	%
Research and development credits		(2.7	)		(3.5	)		(10.1	)
Tax on international activities		(0.6	)		(1.2	)		(2.4	)
Tax deductible dividends		(0.8	)		(0.9	)		(2.2	)
State income tax provision, net of effect on U.S. federal tax		0.7			1.8			2.2
Medicare Part D law change					3.3

Other provision adjustments		1.4			0.2			0.4
Effective income tax rate		25.6	%		26.5	%		22.9	%

During the fourth quarter of 2011, a tax benefit of $397 was recorded as a result of settling the 2004-2006 federal tax audit. During the fourth quarter we received an audit report for the 2007-2008 IRS examination for which we are filing an appeal. We are also subject to examination in major state and international jurisdictions for the 2001-2011 tax years. We believe appropriate provisions for all outstanding tax issues have been made for all jurisdictions and all open years.

Significant components of our deferred tax assets, net of deferred tax liabilities, at December 31 were as follows:

	2011			2010
Retiree health care accruals	$	2,820		$	3,061
Inventory and long-term contract methods of income recognition, fixed assets and other (net of valuation allowance of $27 and $27)		(5,189	)		(2,644	)
Partnerships and joint ventures		(228	)		(263	)
Other employee benefits accruals		1,352			1,272
In-process research and development related to acquisitions		51			65
Net operating loss, credit and capital loss carryovers (net of valuation allowance of $74 and $78)		488			300
Pension asset		5,315			3,443
Customer and commercial financing		(1,471	)		(1,645	)
Unremitted earnings of non-U.S. subsidiaries		(66	)		(60	)
Other net unrealized losses		69			13
Net deferred tax assets(1)	$	3,141		$	3,542

⁽¹⁾  Of the deferred tax asset for net operating loss and credit carryovers, $336 expires in years ending from December 31, 2012 through December 31, 2031 and $152 may be carried over indefinitely.

Net deferred tax assets at December 31 were as follows:

	2011			2010
Deferred tax assets	$	16,181		$	14,383
Deferred tax liabilities		(12,939	)		(10,736	)
Valuation allowance		(101	)		(105	)
Net deferred tax assets	$	3,141		$	3,542

The measurement of deferred tax assets is reduced by a valuation allowance if, based upon available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. Included in the net deferred tax assets at December 31, 2011 and 2010 are deferred tax assets in the amounts of $9,743 and $8,186 related to Accumulated other comprehensive loss.

We have provided for U.S. deferred income taxes and foreign withholding tax in the amount of $66 on undistributed earnings not considered permanently reinvested in our non-U.S. subsidiaries. We have not provided for U.S. deferred income taxes or foreign withholding tax on the remainder of undistributed earnings from our non-U.S. subsidiaries because such earnings are considered to be permanently reinvested and it is not practicable to estimate the amount of tax that may be payable upon distribution.

As of December 31, 2011 and 2010, the amounts accrued for the payment of income tax-related interest and penalties included in the Consolidated Statements of Financial Position were as follows: interest of $48 and $170 and penalties of $10 and $12. The amounts of interest (benefit)/expense were ($94), ($105), and $45 for the years ended December 31, 2011, 2010, and 2009, respectively. The interest benefits recorded during 2011 and 2010 were primarily related to the 2004-2006 and 1998-2003 federal audit settlements.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

	2011			2010			2009
Unrecognized tax benefits – January 1	$	1,198		$	1,787		$	1,453
Gross increases – tax positions in prior periods		154			95			219
Gross decreases – tax positions in prior periods		(383	)		(465	)		(31	)
Gross increases – current-period tax positions		28			76			148
Gross decreases – current-period tax positions		(15	)		(40	)
Settlements		(42	)		(254	)
Lapse of statute of limitations		(1	)		(1	)		(2	)
Unrecognized tax benefits – December 31	$	939		$	1,198		$	1,787

As of December 31, 2011, 2010 and 2009, the total amount of unrecognized tax benefits was $939, $1,198, and $1,787 of which $838, $1,074, and $1,452 would affect the effective tax rate, if recognized. As of December 31, 2011, these amounts are primarily associated with U.S. federal tax issues such as the amount of research and development tax credits claimed, the domestic production activities deductions claimed, and U.S. taxation of foreign earnings. Also included in these amounts are accruals for domestic state tax issues such as the allocation of income among various state tax jurisdictions and the amount of state tax credits claimed.

The research and development credit expired on December 31, 2011. Members of Congress have introduced bills that would extend the credit. If the Research and Development credit is not extended there would be an unfavorable impact to our 2012 effective income tax rate. For the years ended December 31, 2011, 2010 and 2009, the Research and Development credit reduced our effective tax rate by 2.7%, 3.5%, and 10.1%, respectively.

Long-Term Contracts in Progress

Long-term contracts in progress included Delta launch program inventory that will be sold at cost to United Launch Alliance (ULA) under an inventory supply agreement that terminates on March 31, 2021. At December 31, 2011 and 2010, the inventory balance was $1,085 and $1,385. As of December 31, 2011, $739 of this inventory relates to yet unsold launches. ULA is continuing to assess the future of the Delta II program. In the event ULA is unable to sell additional Delta II inventory, our earnings could be reduced by up to $58. See Note 13.

Inventory balances included $236 subject to claims or other uncertainties relating to the A-12 program as of December 31, 2011 and 2010. See Note 21.

Capitalized precontract costs of $1,728 and $527 at December 31, 2011 and 2010, are included in long-term contracts in progress inventories.

Commercial Aircraft Programs

As of December 31, 2011 and 2010, commercial aircraft programs inventory included the following amounts related to the 787 program: $16,098 and $9,461 of work in process (including deferred production costs at December 31, 2011 of $10,753), $1,770 and $1,956 of supplier advances, and $1,914 and $1,447 of unamortized tooling and other non-recurring costs. At December 31, 2011, $9,168 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 $3,499 is expected to be recovered from units included in the program accounting quantity that represent expected future orders.

Commercial aircraft programs inventory included the following amounts related to the 747 program: $448 of deferred production costs at December 31, 2011, net of previously recorded reach-forward losses, and $852 and $879 of unamortized tooling costs at December 31, 2011 and 2010. During the third quarter of 2011, we reclassified $1,934 of previously recorded reach-forward losses on the 747 program from Accrued liabilities to Inventories, net of advances and progress billings. At December 31, 2011, $903 of 747 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 $397 is expected to be recovered from units included in the program accounting quantity that represent expected future orders.

Commercial aircraft program inventory included amounts credited in cash or other consideration (early issue sales consideration), to airline customers totaling $2,564 and $1,970 at December 31, 2011 and 2010.

As a normal course of our Commercial Airplanes segment production process, our inventory may include a small quantity of airplanes that are completed but unsold. As of December 31, 2011, these aircraft were valued at $509. As of December 31, 2010 the value of completed but unsold aircraft in inventory was insignificant.

Summary Of Significant Accounting Policies (Policy)

Summary Of Significant Accounting Policies [Abstract]

Principles Of Consolidation And Basis Of Presentation

Principles of Consolidation and Basis of Presentation

The Consolidated 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"). These statements include the accounts of all majority-owned subsidiaries and variable interest entities that are required to be consolidated. All significant intercompany accounts and transactions have been eliminated. Certain amounts have been reclassified to conform to the current year presentation.

Use Of Estimates

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 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 Consolidated Financial Statements.

Operating Cycle

Operating Cycle

For classification of certain current assets and liabilities, we use the duration of the related contract or program as our operating cycle, which is generally longer than one year and could exceed three years.

Revenue And Related Cost Recognition

Revenue and Related Cost Recognition

Contract Accounting Contract accounting is used for development and production activities predominantly by Boeing Defense, Space & Security (BDS). The majority of business conducted by BDS is performed under contracts with the U.S. government and other customers that extend over several years. Contract accounting involves a judgmental process of estimating the total sales and costs for each contract resulting in the development of estimated cost of sales percentages. For each contract, the amount reported as cost of sales is determined by applying the estimated cost of sales percentage to the amount of revenue recognized.

Changes in estimated revenues, cost of sales and the related effect to 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. In 2011, 2010 and 2009 net favorable cumulative catch-up adjustments increased operating earnings by $229, $125 and $29 respectively and EPS by $0.23, $0.12 and $0.03 respectively. Significant adjustments recorded during the three years ended December 31, 2011 relate to reach-forward losses on the AEW&C and the KC-767 International Tanker programs.

We combine contracts for accounting purposes when they are negotiated as a package with an overall profit margin objective. These essentially represent an agreement to do a single project for a single customer, involve interrelated construction activities with substantial common costs, and are performed concurrently or sequentially. When a group of contracts is combined, revenue and profit are earned uniformly over the performance of the combined contracts. Similarly, we may segment a single contract or group of contracts when a clear economic decision has been made during contract negotiations that would produce different rates of profitability for each element or phase of the contract.

Sales related to fixed-price contracts are recognized as deliveries are made, except for certain fixed-price contracts that require substantial performance over an extended period before deliveries begin, for which sales are recorded based on the attainment of performance milestones. Sales related to contracts in which we are reimbursed for costs incurred plus an agreed upon profit are recorded as costs are incurred. The Federal Acquisition Regulations provide guidance on the types of cost that will be reimbursed in establishing contract price. Contracts may contain provisions to earn incentive and award fees if specified targets are achieved. Incentive and award fees that can be reasonably estimated and are probable are recorded over the performance period of the contract. Incentive and award fees that cannot be reasonably estimated are recorded when awarded.

Program Accounting Our Commercial Airplanes segment predominantly uses program accounting to account for cost of sales related to its programs. Program accounting is applicable to products manufactured for delivery under production-type contracts where profitability is realized over multiple contracts and years. Under program accounting, inventoriable production costs, program tooling and other non-recurring costs, and routine warranty costs are accumulated and charged to cost of sales by program instead of by individual units or contracts. A program consists of the estimated number of units (accounting quantity) of a product to be produced in a continuing, long-term production effort for delivery under existing and anticipated contracts. The determination of the accounting quantity is limited by the ability to make reasonably dependable estimates of the revenue and cost of existing and anticipated contracts. To establish the relationship of sales to cost of sales, program accounting requires estimates of (a) the number of units to be produced and sold in a program, (b) the period over which the units can reasonably be expected to be produced, and (c) the units' expected sales prices, production costs, program tooling and other non-recurring costs, and routine warranty costs for the total program.

We recognize sales for commercial airplane deliveries as each unit is completed and accepted by the customer. Sales recognized represent the price negotiated with the customer, adjusted by an escalation formula as specified in the customer agreement. The amount reported as cost of sales is determined by applying the estimated cost of sales percentage for the total remaining program to the amount of sales recognized for airplanes delivered and accepted by the customer. Changes in estimated revenues, cost of sales and the related effects on program margins are recognized prospectively except in cases where the program is determined to have a reach-forward loss in which case the loss is recognized in the current period.

Concession Sharing Arrangements We account for sales concessions to our customers in consideration of their purchase of products and services as a reduction to revenue when the related products and services are delivered. The sales concessions incurred may be partially reimbursed by certain suppliers in accordance with concession sharing arrangements. We record these reimbursements, which are presumed to represent reductions in the price of the vendor's products or services, as a reduction in Cost of products.

Spare Parts Revenue We recognize sales of spare parts upon delivery and the amount reported as cost of sales is recorded at average cost.

Service Revenue Service revenue is recognized when the service is performed with the exception of U.S. government service agreements, which are accounted for using contract accounting. Service activities primarily include: support agreements associated with military aircraft and helicopter contracts, ongoing maintenance of International Space Station and Space Shuttle, commercial Delta launches and technical and flight operation services for commercial aircraft. Service revenue and associated cost of sales from pay-in-advance subscription fees are deferred and recognized as services are rendered.

Financial Services Revenue We record financial services revenue associated with sales-type/finance leases, operating leases, and notes receivable.

Lease and financing revenue arrangements are included in Sales of services on the Consolidated Statements of Operations. For sales-type/finance leases, we record an asset at lease inception. This asset is recorded at the aggregate future minimum lease payments, estimated residual value of the leased equipment, and deferred incremental direct costs less unearned income. Income is recognized over the life of the lease to approximate a level rate of return on the net investment. Residual values, which are reviewed periodically, represent the estimated amount we expect to receive at lease termination from the disposition of the leased equipment. Actual residual values realized could differ from these estimates. Declines in estimated residual value that are deemed other-than-temporary are recognized as Cost of services in the period in which the declines occur.

For operating leases, revenue on leased aircraft and equipment is recorded on a straight-line basis over the term of the lease. Operating lease assets, included in Customer financing, are recorded at cost and depreciated over the period that we project we will hold the asset to an estimated residual value, using the straight-line method. We periodically review our estimates of residual value and recognize forecasted changes by prospectively adjusting depreciation expense.

For notes receivable, notes are recorded net of any unamortized discounts and deferred incremental direct costs. Interest income and amortization of any discounts are recorded ratably over the related term of the note.

Reinsurance Revenue Our wholly-owned insurance subsidiary, Astro Ltd., participates in a reinsurance pool for workers' compensation. The member agreements and practices of the reinsurance pool minimize any participating members' individual risk. Reinsurance revenues were $144, $139 and $122 during 2011, 2010 and 2009, respectively. Reinsurance costs related to premiums and claims paid to the reinsurance pool were $142, $123 and $118 during 2011, 2010 and 2009, respectively. Revenues and costs are presented net in Cost of services in the Consolidated Statements of Operations.

Fleet Support

Fleet Support

We provide assistance and services to facilitate efficient and safe aircraft operation to the operators of all our commercial airplane models. Collectively known as fleet support services, these activities and services include flight and maintenance training, field service support, engineering services, and technical data and documents. Fleet support activity begins prior to aircraft delivery as the customer receives training, manuals, and technical consulting support. This activity continues throughout the aircraft's operational life. Services provided after delivery include field service support, consulting on maintenance, repair, and operational issues brought forth by the customer or regulators, updating manuals and engineering data, and the issuance of service bulletins that impact the entire model's fleet. Field service support involves our personnel located at customer facilities providing and coordinating fleet support activities and requests. The costs for fleet support are expensed as incurred as Cost of services.

Research And Development

Research and Development

Research and development includes costs incurred for experimentation, design, testing, and bid and proposal efforts related to government products and services which are expensed as incurred unless the costs are related to certain contractual arrangements with customers. Costs that are incurred pursuant to such contractual arrangements are recorded over the period that revenue is recognized, consistent with our contract accounting policy. We have certain research and development arrangements that meet the requirement for best efforts research and development accounting. Accordingly, the amounts funded by the customer are recognized as an offset to our research and development expense rather than as contract revenues.

We have established cost sharing arrangements with some suppliers for the 787 program. Our cost sharing arrangements state that the supplier contributions are for reimbursements of costs we incur for experimentation, basic design, and testing activities during the 787 development. In each arrangement, we retain substantial rights to the 787 part or component covered by the arrangement. The amounts received from these cost sharing arrangements are recorded as a reduction to research and development expenses since we have no obligation to refund any amounts received per the arrangements regardless of the outcome of the development efforts. Specifically, under the terms of each agreement, payments received from suppliers for their share of the costs are typically based on milestones and are recognized as earned when we achieve the milestone events and no ongoing obligation on our part exists. In the event we receive a milestone payment prior to the completion of the milestone, the amount is classified in Accrued liabilities until earned.

Share-Based Compensation

Share-Based Compensation

We provide various forms of share-based compensation to our employees. For awards settled in shares, we measure compensation expense based on the grant-date fair value net of estimated forfeitures. For awards settled in cash, or that may be settled in cash, we measure compensation expense based on the fair value at each reporting date net of estimated forfeitures. The expense is recognized over the requisite service period, which is generally the vesting period of the award.

Income Taxes

Income Taxes

Provisions for federal, state, and non-U.S. income taxes are calculated on reported Earnings before income taxes based on current tax law and also include, in the current period, the cumulative effect of any changes in tax rates from those used previously in determining deferred tax assets and liabilities. Such provisions differ from the amounts currently receivable or payable because certain items of income and expense are recognized in different time periods for financial reporting purposes than for income tax purposes. Significant judgment is required in determining income tax provisions and evaluating tax positions.

The accounting for uncertainty in income taxes requires a more-likely-than-not threshold for financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. We record a liability for the difference between the benefit recognized and measured for financial statement purposes and the tax position taken or expected to be taken on our tax return. To the extent that our assessment of such tax positions changes, the change in estimate is recorded in the period in which the determination is made. Tax-related interest and penalties are classified as a component of Income tax expense.

Postretirement Plans

Postretirement Plans

The majority of our employees are covered by defined benefit pension plans. All nonunion and some union employees hired after December 31, 2008 are not covered by defined benefit plans. We also provide postretirement benefit plans other than pensions, consisting principally of health care coverage to eligible retirees and qualifying dependents. Benefits under the pension and other postretirement benefit plans are generally based on age at retirement and years of service and, for some pension plans, benefits are also based on the employee's annual earnings. The net periodic cost of our pension and other postretirement plans is determined using the projected unit credit method and several actuarial assumptions, the most significant of which are the discount rate, the long-term rate of asset return, and medical trend (rate of growth for medical costs). A portion of net periodic pension and other postretirement income or expense is not recognized in net earnings in the year incurred because it is allocated to production as product costs, and reflected in inventory at the end of a reporting period. Actuarial gains and losses, which occur when actual experience differs from actuarial assumptions, are reflected in Shareholders' equity (net of taxes). If actuarial gains and losses exceed ten percent of the greater of plan assets or plan liabilities we amortize them over the average future service period of employees. The funded status of our pension and postretirement plans is reflected on the Consolidated Statements of Financial Position.

Postemployment Plans

Postemployment Plans

We record a liability for postemployment benefits, such as severance or job training, when payment is probable, the amount is reasonably estimable, and the obligation relates to rights that have vested or accumulated.

Environmental Remediation

Environmental Remediation

We are subject to federal and state requirements for protection of the environment, including those for discharge of hazardous materials and remediation of contaminated sites. We routinely assess, based on in-depth studies, expert analyses and legal reviews, our contingencies, obligations, and commitments for remediation of contaminated sites, including assessments of ranges and probabilities of recoveries from other responsible parties and/or insurance carriers. Our policy is to accrue and charge to current expense identified exposures related to environmental remediation sites when it is probable that a liability has been incurred and the amount can be reasonably estimated. The amount of the liability is based on our best estimate or the low end of a range of reasonably possible exposure for investigation, cleanup, and monitoring costs to be incurred. Estimated remediation costs are not discounted to present value as the timing of payments cannot be reasonably estimated. We may be able to recover a portion of the remediation costs from insurers or other third parties. Such recoveries are recorded when realization of the claim for recovery is deemed probable.

Cash And Cash Equivalents

Cash and Cash Equivalents

Cash and cash equivalents consist of highly liquid instruments, such as commercial paper, time deposits, and other money market instruments, which have original maturities of three months or less. We aggregate our cash balances by bank where conditions for right of set-off are met, and reclassify any negative balances, consisting mainly of uncleared checks, to Accounts payable. Negative balances reclassified to Accounts payable were $132 and $209 at December 31, 2011 and 2010.

Inventories

Inventories

Inventoried costs on commercial aircraft programs and long-term contracts include direct engineering, production and tooling and other non-recurring costs, and applicable overhead, which includes fringe benefits, production related indirect and plant management salaries and plant services, not in excess of estimated net realizable value. To the extent a material amount of such costs are related to an abnormal event or are fixed costs not appropriately attributable to our programs or contracts, they are expensed in the current period rather than inventoried. Inventoried costs include amounts relating to programs and contracts with long-term production cycles, a portion of which is not expected to be realized within one year. Included in inventory for federal government contracts is an allocation of allowable costs related to manufacturing process reengineering.

Commercial aircraft programs inventory includes deferred production costs. Deferred production costs represent actual costs incurred for production of early units that exceed the estimated average cost of all units in the program accounting quantity. Higher production costs are experienced at the beginning of a new or derivative airplane program. Units produced early in a program require substantially more effort (labor and other resources) than units produced later in a program because of volume efficiencies and the effects of learning. We expect that these deferred costs will be fully recovered when all units included in the accounting quantity are delivered as the expected unit cost for later deliveries is below the estimated average cost of all units in the program.

The determination of net realizable value of long-term contract costs is based upon quarterly reviews that estimate costs to be incurred to complete all contract requirements. When actual contract costs and the estimate to complete exceed total estimated contract revenues, a loss provision is recorded. The determination of net realizable value of commercial aircraft program costs is based upon quarterly program reviews that estimate revenue and cost to be incurred to complete the program accounting quantity. When estimated costs to complete exceed estimated program revenues to go, a program loss provision is recorded in the current period for the estimated loss on all undelivered units in the accounting quantity.

Used aircraft purchased by the Commercial Airplanes segment and general stock materials are stated at cost not in excess of net realizable value. See 'Aircraft Valuation' within this Note for a discussion of our valuation of used aircraft. Spare parts inventory is stated at lower of average unit cost or market. We review our commercial spare parts and general stock materials quarterly to identify impaired inventory, including excess or obsolete inventory, based on historical sales trends, expected production usage, and the size and age of the aircraft fleet using the part. Impaired inventories are charged to Cost of products in the period the impairment occurs.

Included in inventory for commercial aircraft programs are amounts paid or credited in cash, or other consideration to certain airline customers, that are referred to as early issue sales consideration. Early issue sales consideration is recognized as a reduction to revenue when the delivery of the aircraft under contract occurs. If an airline customer does not perform and take delivery of the contracted aircraft, we believe that we would have the ability to recover amounts paid. However, to the extent early issue sales consideration exceeds advances and is not considered to be otherwise recoverable, it would be written off in the current period.

We net advances and progress billings on long-term contracts against inventory in the Consolidated Statements of Financial Position. Advances and progress billings in excess of related inventory are reported in Advances and billings in excess of related costs.

Precontract Costs

Precontract Costs

We may, from time to time, incur costs to begin fulfilling the statement of work under a specific anticipated contract that we are still negotiating with a customer. If we determine it is probable that we will be awarded the specific anticipated contract, then we capitalize the precontract costs we incur, excluding start-up costs which are expensed as incurred. Capitalized precontract costs are included in Inventories, net of advances and progress billings, in the accompanying Consolidated Statements of Financial Position. Should the contract not be awarded or otherwise determined to no longer be probable of award, the capitalized costs would be written off.

Property, Plant And Equipment

Property, Plant and Equipment

Property, plant and equipment are recorded at cost, including applicable construction-period interest, less accumulated depreciation and are depreciated principally over the following estimated useful lives: new buildings and land improvements, from 10 to 40 years; and new machinery and equipment, from 3 to 20 years. The principal methods of depreciation are as follows: buildings and land improvements, 150% declining balance; and machinery and equipment, sum-of-the-years' digits. Capitalized internal use software is included in Other assets and amortized using the straight line method over five years. We periodically evaluate the appropriateness of remaining depreciable lives assigned to long-lived assets, including assets that may be subject to a management plan for disposition.

Long-lived assets held for sale are stated at the lower of cost or fair value less cost to sell. Long-lived assets held for use are subject to an impairment assessment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the carrying value is no longer recoverable based upon the undiscounted future cash flows of the asset, the amount of the impairment is the difference between the carrying amount and the fair value of the asset.

Asset Retirement Obligations

Asset Retirement Obligations

We record all known asset retirement obligations for which the liability's fair value can be reasonably estimated, including certain asbestos removal, asset decommissioning and contractual lease restoration obligations. Recorded amounts are not material.

We also have known conditional asset retirement obligations, such as certain asbestos remediation and asset decommissioning activities to be performed in the future, that are not reasonably estimable due to insufficient information about the timing and method of settlement of the obligation. Accordingly, these obligations have not been recorded in the Consolidated Financial Statements. A liability for these obligations will be recorded in the period when sufficient information regarding timing and method of settlement becomes available to make a reasonable estimate of the liability's fair value. In addition, there may be conditional asset retirement obligations that we have not yet discovered (e.g. asbestos may exist in certain buildings but we have not become aware of it through the normal course of business), and therefore, these obligations also have not been included in the Consolidated Financial Statements.

Goodwill And Other Acquired Intangibles

Goodwill and Other Acquired Intangibles

Goodwill and other acquired intangible assets with indefinite lives are not amortized, but are tested for impairment annually and when an event occurs or circumstances change such that it is more likely than not that an impairment may exist. Our annual testing date is April 1.

We test goodwill for impairment by first comparing the carrying value of net assets to the fair value of the related operations. If the fair value is determined to be less than carrying value, a second step is performed to compute the amount of the impairment. In this process, a fair value for goodwill is estimated, based in part on the fair value of the operations, and is compared to its carrying value. The shortfall of the fair value below carrying value represents the amount of goodwill impairment.

Indefinite-lived intangibles consist of brand and tradenames acquired in business combinations. We test these intangibles for impairment by comparing their carrying value to current projections of discounted cash flows attributable to the brand and tradenames. Any excess carrying value over the amount of discounted cash flows represents the amount of the impairment.

Our finite-lived acquired intangible assets are amortized on a straight-line basis over their estimated useful lives as follows: developed technology, from 4 to 14 years; product know-how, from 3 to 30 years; customer base, from 3 to 19 years; distribution rights, from 3 to 30 years; and other, from 1 to 32 years. We evaluate the potential impairment of finite-lived acquired intangible assets whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the carrying value is no longer recoverable based upon the undiscounted future cash flows of the asset, the amount of the impairment is the difference between the carrying amount and the fair value of the asset.

Investments

Investments

Time deposits are held-to-maturity investments that are carried at cost.

The equity method of accounting is used to account for investments for which we have the ability to exercise significant influence, but not control, over an investee. Significant influence is generally deemed to exist if we have an ownership interest in the voting stock of an investee of between 20% and 50%.

We classify investment income and loss on our Consolidated Statements of Operations based on whether the investment is operating or non-operating in nature. Operating investments align strategically and are integrated with our operations. Earnings from operating investments, including our share of income or loss from equity method investments, dividend income from certain cost method investments, and any impairments or gain/loss on the disposition of these investments, are recorded in Income from operating investments, net. Non-operating investments are those we hold for non-strategic purposes. Earnings from non-operating investments, including interest and dividends on marketable securities, and any impairments or gain/loss on the disposition of these investments are recorded in Other income/(expense), net.

Derivatives

Derivatives

All derivative instruments are recognized in the financial statements and measured at fair value regardless of the purpose or intent of holding them. We use derivative instruments to principally manage a variety of market risks. For derivatives designated as hedges of the exposure to changes in fair value of the recognized asset or liability or a firm commitment (referred to as fair value hedges), the gain or loss is recognized in earnings in the period of change together with the offsetting loss or gain on the hedged item attributable to the risk being hedged. The effect of that accounting is to include in earnings the extent to which the hedge is not effective in achieving offsetting changes in fair value. For our cash flow hedges, the effective portion of the derivative's gain or loss is initially reported in Shareholders' equity (as a component of Accumulated other comprehensive loss) and is subsequently reclassified into earnings in the same period or periods during which the hedged forecasted transaction affects earnings. The ineffective portion of the gain or loss of a cash flow hedge is reported in earnings immediately. We also hold certain instruments for economic purposes that are not designated for hedge accounting treatment. For these derivative instruments, the changes in their fair value are also recorded in earnings immediately.

Aircraft Valuation

Aircraft Valuation

Used aircraft under trade-in commitments and aircraft under repurchase commitments In conjunction with signing a definitive agreement 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. Additionally, we have entered into contingent repurchase commitments with certain customers wherein we agree to repurchase the Sale Aircraft at a specified price, generally 10 to 15 years after delivery of the Sale Aircraft. Our repurchase of the Sale Aircraft is contingent upon a future, mutually acceptable agreement for the sale of additional new aircraft. If we execute an agreement for the sale of additional new aircraft, and if the customer exercises its right to sell the Sale Aircraft to us, a contingent repurchase commitment would become a trade-in commitment. Our historical experience is that contingent repurchase commitments infrequently become trade-in commitments.

All trade-in commitments at December 31, 2011 and 2010 were solely attributable to Sale Aircraft and did not originate from contingent repurchase commitments. Exposure related to trade-in commitments may take the form of:

(1) adjustments to revenue for the difference between the contractual trade-in price in the definitive agreement and our best estimate of the fair value of the trade-in aircraft as of the date of such agreement, which would be recorded in Inventory and recognized upon delivery of the Sale Aircraft, and/or

(2) charges to cost of products for adverse changes in the fair value of trade-in aircraft that occur subsequent to signing of a definitive agreement for Sale Aircraft but prior to the purchase of the used trade-in aircraft. Estimates based on current aircraft values would be included in Accrued liabilities.

The fair value of trade-in aircraft is determined using aircraft-specific data such as model, age and condition, market conditions for specific aircraft and similar models, and multiple valuation sources. This process uses our assessment of the market for each trade-in aircraft, which in most instances begins years before the return of the aircraft. There are several possible markets in which we continually pursue opportunities to place used aircraft. These markets include, but are not limited to, the resale market, which could potentially include the cost of long-term storage; the leasing market, with the potential for refurbishment costs to meet the leasing customer's requirements; or the scrap market. Trade-in aircraft valuation varies significantly depending on which market we determine is most likely for each aircraft. On a quarterly basis, we update our valuation analysis based on the actual activities associated with placing each aircraft into a market. This quarterly valuation process yields results that are typically lower than residual value estimates by independent sources and tends to more accurately reflect results upon the actual placement of the aircraft.

Used aircraft acquired by the Commercial Airplanes segment are included in Inventories at the lower of cost or market as it is our intent to sell these assets. To mitigate costs and enhance marketability, aircraft may be placed on operating lease. While on operating lease, the assets are included in Customer financing.

Assets under operating lease, assets held for sale or re-lease and collateral underlying receivables Customer financing includes operating lease equipment, notes receivables, and sales-type/finance leases. Sales-type/finance leases are treated as receivables, and allowances for losses are established as necessary.

We assess the fair value of the assets we own, including equipment under operating leases, assets held for sale or re-lease, and collateral underlying receivables, to determine if their fair values are less than the related assets' carrying values. Differences between carrying values and fair values of sales-type/finance leases and notes and other receivables, as determined by collateral value, are considered in determining the allowance for losses on receivables.

We use a median calculated from published collateral values from multiple third-party aircraft value publications based on the type and age of the aircraft to determine the fair value of aircraft. Under certain circumstances, we apply judgment based on the attributes 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 outside publications.

Impairment review for assets under operating leases and held for sale or re-lease We evaluate for impairment assets under operating lease or assets held for sale or re-lease when events or changes in circumstances indicate that the expected undiscounted cash flow from the asset may be less than the carrying value. We use various assumptions when determining the expected undiscounted cash flow, including our intentions for how long we will hold an asset subject to operating lease before it is sold, the expected future lease rates, lease terms, residual value of the asset, periods in which the asset may be held in preparation for a follow-on lease, maintenance costs, remarketing costs and the remaining economic life of the asset. We record assets held for sale at the lower of carrying value or fair value less costs to sell.

When we determine that impairment is indicated for an asset, the amount of impairment expense recorded is the excess of the carrying value over the fair value of the asset.

Allowance for losses on customer financing receivables We record the potential impairment of customer financing receivables in our portfolio in a valuation account, the balance of which is an accounting estimate of probable but unconfirmed losses in the receivables portfolio. The allowance for losses on receivables relates to two components of receivables: (a) receivables that are evaluated individually for impairment and (b) all other receivables.

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 of the receivable agreement, without regard to any subsequent restructurings. Factors considered in assessing collectibility include, but are not limited to, a customer's extended delinquency, requests for restructuring and filings for bankruptcy. We determine a specific impairment allowance based on the difference between the carrying value of the receivable and the estimated fair value of the related collateral we would expect to realize.

We review the adequacy of the allowance attributable to the remaining receivables (after excluding receivables subject to a specific impairment allowance) by assessing both the collateral exposure and the applicable cumulative default rate. Collateral exposure for a particular receivable is the excess of the carrying value of the receivable over the fair value of the related collateral. A receivable with an estimated fair value in excess of the carrying value is considered to have no collateral exposure. The applicable cumulative default rate is determined using two components: customer credit ratings and weighted average remaining contract term. Internally assigned credit ratings, our credit quality indicator, are determined for each customer in the portfolio. Those ratings are updated based upon public information and information obtained directly from our customers.

We have entered into agreements with certain customers that would entitle us to look beyond the specific collateral underlying the receivable for purposes of determining the collateral exposure as described above. Should the proceeds from the sale of the underlying collateral asset resulting from a default condition be insufficient to cover the carrying value of our receivable (creating a shortfall condition), these agreements would, for example, permit us to take the actions necessary to sell or retain certain other assets in which the customer has an equity interest and use the proceeds to cover the shortfall.

Each quarter we review customer credit ratings, published historical credit default rates for different rating categories, and multiple third-party aircraft value publications as a basis to validate the reasonableness of the allowance for losses on receivables. There can be no assurance that actual results will not differ from estimates or that the consideration of these factors in the future will not result in an increase or decrease to the allowance for losses on receivables.

Warranties

Warranties

In conjunction with certain product sales, we provide warranties that cover factors such as non-conformance to specifications and defects in material and design. The majority of our warranties are issued by our Commercial Airplanes segment. Generally, aircraft sales are accompanied by a three to four-year standard warranty for systems, accessories, equipment, parts, and software manufactured by us or manufactured to certain standards under our authorization. These warranties are included in the programs' estimate at completion. On occasion we have made commitments beyond the standard warranty obligation to correct fleet-wide major issues of a particular model, resulting in additional accrued warranty expense. Warranties issued by our BDS segments principally relate to sales of military aircraft and weapons hardware and are included in the contract cost estimates. These sales are generally accompanied by a six to twelve-month warranty period and cover systems, accessories, equipment, parts, and software manufactured by us to certain contractual specifications. Estimated costs related to standard warranties are recorded in the period in which the related product sales occur. The warranty liability recorded at each balance sheet date reflects the estimated number of months of warranty coverage outstanding for products delivered times the average of historical monthly warranty payments, as well as additional amounts for certain major warranty issues that exceed a normal claims level. Estimated costs of these additional warranty issues are considered changes to the initial liability estimate.

We provide guarantees to certain commercial airplane customers which include compensation provisions for failure to meet specified aircraft performance targets. We account for these performance guarantees as warranties. The estimated liability for these warranties is based on known and anticipated operational characteristics and forecasted customer operation of the aircraft relative to contractually specified performance targets, and anticipated settlements when contractual remedies are not specified. Estimated payments are recorded as a reduction of revenue at delivery of the related aircraft. We have agreements that require certain suppliers to compensate us for amounts paid to customers for failure of supplied equipment to meet specified performance targets. Claims against suppliers under these agreements are included in Inventories and recorded as a reduction in Cost of products at delivery of the related aircraft. These performance warranties and claims against suppliers are included in the programs' estimate at completion.

Supplier Penalties

Supplier Penalties

We record an accrual for supplier penalties when an event occurs that makes it probable that a supplier penalty will be incurred and the amount is reasonably estimable. Until an event occurs, we fully anticipate accepting all products procured under production-related contracts.

Guarantees

Guarantees

We record a liability in Accrued liabilities for the fair value of guarantees that are issued or modified after December 31, 2002. For a residual value guarantee where we received a cash premium, the liability is equal to the cash premium received at the guarantee's inception. For credit and performance guarantees, the liability is equal to the present value of the expected loss. We determine the expected loss by multiplying the creditor's default rate by the guarantee amount reduced by the expected recovery, if applicable, for each future period the credit or performance guarantee will be outstanding. If at inception of a guarantee, we determine there is a probable related contingent loss, we will recognize a liability for the greater of (a) the fair value of the guarantee as described above or (b) the probable contingent loss amount.

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 the discovery of additional contamination. As part of our estimating process, we develop a range of reasonably possible alternate scenarios which include 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 December 31, 2011 and 2010, the high end of the estimated range of reasonably possible remediation costs exceeded our recorded liabilities by $1,003 and $957.

Commercial Aircraft Commitments

In conjunction with signing definitive agreements for the sale of new aircraft (Sale Aircraft), we have entered into specified-price trade-in commitments with certain customers that give them the right to trade in used aircraft upon the purchase of Sale Aircraft. The total contractual trade-in value was $273 and $295 as of December 31, 2011 and 2010. We anticipate that a significant portion of these commitments will not be exercised by customers.

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 take into consideration the current economic environment. 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. The fair value of trade-in aircraft related to probable contractual trade-in commitments was $27 and $30 as of December 31, 2011 and 2010. Trade-in commitment agreements have expiration dates from 2012 through 2023.

Financing Commitments

Financing commitments totaled $15,866 and $9,865 as of December 31, 2011 and 2010. The estimated earliest potential funding dates for these commitments as of December 31, 2011 are as follows:

	Total
2012	$	1,562
2013		1,207
2014		2,217
2015		3,639
2016		2,475
Thereafter		4,766
	$	15,866

Standby Letters of Credit and Surety Bonds

We have entered into standby letters of credit agreements 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 $6,199 and $7,599 as of December 31, 2011 and 2010.

Commitments to ULA

We and Lockheed have each committed to provide ULA with up to $352 of additional capital contributions in the event ULA does not have sufficient funds to make a required payment to us under an inventory supply agreement. See Note 7.

C-17

At December 31, 2011, our backlog included 3 C-17 aircraft currently under contract with the U.S. Air Force (USAF) as well as international orders for 2 aircraft. The probable orders, not under contract at December 31, 2011, totaled 19 aircraft of which 13 were for international customers and 6 for the USAF. USAF orders included 5 aircraft for which a contract was received in January 2012 and 1 aircraft which was funded in the Fiscal Year 2012 Defense Appropriations Act. At December 31, 2011, we had approximately $940 of inventory expenditures and potential termination liabilities to suppliers associated with probable orders, of which $870 was related to the 5 USAF orders and 12 international orders received in January and February 2012. We completed the planned production rate decrease from 15 aircraft per year to 10 per year during the third quarter of 2011. The associated reduction in headcount resulted in pension curtailment charges of $34 in the first quarter of 2011. Should additional orders not materialize, it is reasonably possible that we will decide in 2012 to end production of the C-17 at a future date. We are still evaluating the full financial impact of a potential production shut-down, including additional pension curtailment charges, and any recovery that would be available from the U.S. government. Such recovery from the U.S. government would not include the costs incurred by us resulting from our direction to suppliers to begin working on aircraft beyond those currently under contract with the USAF.

F-15

At December 31, 2011, we had approximately $2,275 of inventory expenditures and potential termination liabilities to suppliers related to the production of F-15 aircraft not currently under contract. On December 29^th, 2011, the Kingdom of Saudi Arabia and the U.S. government announced the signing of a letter of offer and acceptance for a foreign military sale for 84 new F-15SE Eagle fighters and associated products and services. We expect this order to be under contract in 2012.

Company Owned Life Insurance

McDonnell Douglas Corporation insured its executives with Company Owned Life Insurance (COLI), which are life insurance policies with a cash surrender value. Although we do not use COLI currently, these obligations from the merger with McDonnell Douglas are still a commitment at this time. We have loans in place to cover costs paid or incurred to carry the underlying life insurance policies. As of December 31, 2011 and 2010, the cash surrender value was $397 and $381 and the total loans were $377 and $363. As we have the right to offset the loans against the cash surrender value of the policies, we present the net asset in Other assets on the Consolidated Statements of Financial Position as of December 31, 2011 and 2010.

Summary Of Significant Accounting Policies [Abstract]

Summary Of Significant Accounting Policies

Note 1 – Summary of Significant Accounting Policies

Principles of Consolidation and Basis of Presentation

The Consolidated 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"). These statements include the accounts of all majority-owned subsidiaries and variable interest entities that are required to be consolidated. All significant intercompany accounts and transactions have been eliminated. Certain amounts have been reclassified to conform to the current year presentation.

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 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 Consolidated Financial Statements.

Operating Cycle

For classification of certain current assets and liabilities, we use the duration of the related contract or program as our operating cycle, which is generally longer than one year and could exceed three years.

Revenue and Related Cost Recognition

Contract Accounting Contract accounting is used for development and production activities predominantly by Boeing Defense, Space & Security (BDS). The majority of business conducted by BDS is performed under contracts with the U.S. government and other customers that extend over several years. Contract accounting involves a judgmental process of estimating the total sales and costs for each contract resulting in the development of estimated cost of sales percentages. For each contract, the amount reported as cost of sales is determined by applying the estimated cost of sales percentage to the amount of revenue recognized.

Changes in estimated revenues, cost of sales and the related effect to 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. In 2011, 2010 and 2009 net favorable cumulative catch-up adjustments increased operating earnings by $229, $125 and $29 respectively and EPS by $0.23, $0.12 and $0.03 respectively. Significant adjustments recorded during the three years ended December 31, 2011 relate to reach-forward losses on the AEW&C and the KC-767 International Tanker programs.

We combine contracts for accounting purposes when they are negotiated as a package with an overall profit margin objective. These essentially represent an agreement to do a single project for a single customer, involve interrelated construction activities with substantial common costs, and are performed concurrently or sequentially. When a group of contracts is combined, revenue and profit are earned uniformly over the performance of the combined contracts. Similarly, we may segment a single contract or group of contracts when a clear economic decision has been made during contract negotiations that would produce different rates of profitability for each element or phase of the contract.

Sales related to fixed-price contracts are recognized as deliveries are made, except for certain fixed-price contracts that require substantial performance over an extended period before deliveries begin, for which sales are recorded based on the attainment of performance milestones. Sales related to contracts in which we are reimbursed for costs incurred plus an agreed upon profit are recorded as costs are incurred. The Federal Acquisition Regulations provide guidance on the types of cost that will be reimbursed in establishing contract price. Contracts may contain provisions to earn incentive and award fees if specified targets are achieved. Incentive and award fees that can be reasonably estimated and are probable are recorded over the performance period of the contract. Incentive and award fees that cannot be reasonably estimated are recorded when awarded.

Program Accounting Our Commercial Airplanes segment predominantly uses program accounting to account for cost of sales related to its programs. Program accounting is applicable to products manufactured for delivery under production-type contracts where profitability is realized over multiple contracts and years. Under program accounting, inventoriable production costs, program tooling and other non-recurring costs, and routine warranty costs are accumulated and charged to cost of sales by program instead of by individual units or contracts. A program consists of the estimated number of units (accounting quantity) of a product to be produced in a continuing, long-term production effort for delivery under existing and anticipated contracts. The determination of the accounting quantity is limited by the ability to make reasonably dependable estimates of the revenue and cost of existing and anticipated contracts. To establish the relationship of sales to cost of sales, program accounting requires estimates of (a) the number of units to be produced and sold in a program, (b) the period over which the units can reasonably be expected to be produced, and (c) the units' expected sales prices, production costs, program tooling and other non-recurring costs, and routine warranty costs for the total program.

We recognize sales for commercial airplane deliveries as each unit is completed and accepted by the customer. Sales recognized represent the price negotiated with the customer, adjusted by an escalation formula as specified in the customer agreement. The amount reported as cost of sales is determined by applying the estimated cost of sales percentage for the total remaining program to the amount of sales recognized for airplanes delivered and accepted by the customer. Changes in estimated revenues, cost of sales and the related effects on program margins are recognized prospectively except in cases where the program is determined to have a reach-forward loss in which case the loss is recognized in the current period.

Concession Sharing Arrangements We account for sales concessions to our customers in consideration of their purchase of products and services as a reduction to revenue when the related products and services are delivered. The sales concessions incurred may be partially reimbursed by certain suppliers in accordance with concession sharing arrangements. We record these reimbursements, which are presumed to represent reductions in the price of the vendor's products or services, as a reduction in Cost of products.

Spare Parts Revenue We recognize sales of spare parts upon delivery and the amount reported as cost of sales is recorded at average cost.

Service Revenue Service revenue is recognized when the service is performed with the exception of U.S. government service agreements, which are accounted for using contract accounting. Service activities primarily include: support agreements associated with military aircraft and helicopter contracts, ongoing maintenance of International Space Station and Space Shuttle, commercial Delta launches and technical and flight operation services for commercial aircraft. Service revenue and associated cost of sales from pay-in-advance subscription fees are deferred and recognized as services are rendered.

Financial Services Revenue We record financial services revenue associated with sales-type/finance leases, operating leases, and notes receivable.

Lease and financing revenue arrangements are included in Sales of services on the Consolidated Statements of Operations. For sales-type/finance leases, we record an asset at lease inception. This asset is recorded at the aggregate future minimum lease payments, estimated residual value of the leased equipment, and deferred incremental direct costs less unearned income. Income is recognized over the life of the lease to approximate a level rate of return on the net investment. Residual values, which are reviewed periodically, represent the estimated amount we expect to receive at lease termination from the disposition of the leased equipment. Actual residual values realized could differ from these estimates. Declines in estimated residual value that are deemed other-than-temporary are recognized as Cost of services in the period in which the declines occur.

For operating leases, revenue on leased aircraft and equipment is recorded on a straight-line basis over the term of the lease. Operating lease assets, included in Customer financing, are recorded at cost and depreciated over the period that we project we will hold the asset to an estimated residual value, using the straight-line method. We periodically review our estimates of residual value and recognize forecasted changes by prospectively adjusting depreciation expense.

For notes receivable, notes are recorded net of any unamortized discounts and deferred incremental direct costs. Interest income and amortization of any discounts are recorded ratably over the related term of the note.

Reinsurance Revenue Our wholly-owned insurance subsidiary, Astro Ltd., participates in a reinsurance pool for workers' compensation. The member agreements and practices of the reinsurance pool minimize any participating members' individual risk. Reinsurance revenues were $144, $139 and $122 during 2011, 2010 and 2009, respectively. Reinsurance costs related to premiums and claims paid to the reinsurance pool were $142, $123 and $118 during 2011, 2010 and 2009, respectively. Revenues and costs are presented net in Cost of services in the Consolidated Statements of Operations.

Fleet Support

We provide assistance and services to facilitate efficient and safe aircraft operation to the operators of all our commercial airplane models. Collectively known as fleet support services, these activities and services include flight and maintenance training, field service support, engineering services, and technical data and documents. Fleet support activity begins prior to aircraft delivery as the customer receives training, manuals, and technical consulting support. This activity continues throughout the aircraft's operational life. Services provided after delivery include field service support, consulting on maintenance, repair, and operational issues brought forth by the customer or regulators, updating manuals and engineering data, and the issuance of service bulletins that impact the entire model's fleet. Field service support involves our personnel located at customer facilities providing and coordinating fleet support activities and requests. The costs for fleet support are expensed as incurred as Cost of services.

Research and Development

Research and development includes costs incurred for experimentation, design, testing, and bid and proposal efforts related to government products and services which are expensed as incurred unless the costs are related to certain contractual arrangements with customers. Costs that are incurred pursuant to such contractual arrangements are recorded over the period that revenue is recognized, consistent with our contract accounting policy. We have certain research and development arrangements that meet the requirement for best efforts research and development accounting. Accordingly, the amounts funded by the customer are recognized as an offset to our research and development expense rather than as contract revenues.

We have established cost sharing arrangements with some suppliers for the 787 program. Our cost sharing arrangements state that the supplier contributions are for reimbursements of costs we incur for experimentation, basic design, and testing activities during the 787 development. In each arrangement, we retain substantial rights to the 787 part or component covered by the arrangement. The amounts received from these cost sharing arrangements are recorded as a reduction to research and development expenses since we have no obligation to refund any amounts received per the arrangements regardless of the outcome of the development efforts. Specifically, under the terms of each agreement, payments received from suppliers for their share of the costs are typically based on milestones and are recognized as earned when we achieve the milestone events and no ongoing obligation on our part exists. In the event we receive a milestone payment prior to the completion of the milestone, the amount is classified in Accrued liabilities until earned.

Share-Based Compensation

We provide various forms of share-based compensation to our employees. For awards settled in shares, we measure compensation expense based on the grant-date fair value net of estimated forfeitures. For awards settled in cash, or that may be settled in cash, we measure compensation expense based on the fair value at each reporting date net of estimated forfeitures. The expense is recognized over the requisite service period, which is generally the vesting period of the award.

Income Taxes

Provisions for federal, state, and non-U.S. income taxes are calculated on reported Earnings before income taxes based on current tax law and also include, in the current period, the cumulative effect of any changes in tax rates from those used previously in determining deferred tax assets and liabilities. Such provisions differ from the amounts currently receivable or payable because certain items of income and expense are recognized in different time periods for financial reporting purposes than for income tax purposes. Significant judgment is required in determining income tax provisions and evaluating tax positions.

The accounting for uncertainty in income taxes requires a more-likely-than-not threshold for financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. We record a liability for the difference between the benefit recognized and measured for financial statement purposes and the tax position taken or expected to be taken on our tax return. To the extent that our assessment of such tax positions changes, the change in estimate is recorded in the period in which the determination is made. Tax-related interest and penalties are classified as a component of Income tax expense.

Postretirement Plans

The majority of our employees are covered by defined benefit pension plans. All nonunion and some union employees hired after December 31, 2008 are not covered by defined benefit plans. We also provide postretirement benefit plans other than pensions, consisting principally of health care coverage to eligible retirees and qualifying dependents. Benefits under the pension and other postretirement benefit plans are generally based on age at retirement and years of service and, for some pension plans, benefits are also based on the employee's annual earnings. The net periodic cost of our pension and other postretirement plans is determined using the projected unit credit method and several actuarial assumptions, the most significant of which are the discount rate, the long-term rate of asset return, and medical trend (rate of growth for medical costs). A portion of net periodic pension and other postretirement income or expense is not recognized in net earnings in the year incurred because it is allocated to production as product costs, and reflected in inventory at the end of a reporting period. Actuarial gains and losses, which occur when actual experience differs from actuarial assumptions, are reflected in Shareholders' equity (net of taxes). If actuarial gains and losses exceed ten percent of the greater of plan assets or plan liabilities we amortize them over the average future service period of employees. The funded status of our pension and postretirement plans is reflected on the Consolidated Statements of Financial Position.

Postemployment Plans

We record a liability for postemployment benefits, such as severance or job training, when payment is probable, the amount is reasonably estimable, and the obligation relates to rights that have vested or accumulated.

Environmental Remediation

We are subject to federal and state requirements for protection of the environment, including those for discharge of hazardous materials and remediation of contaminated sites. We routinely assess, based on in-depth studies, expert analyses and legal reviews, our contingencies, obligations, and commitments for remediation of contaminated sites, including assessments of ranges and probabilities of recoveries from other responsible parties and/or insurance carriers. Our policy is to accrue and charge to current expense identified exposures related to environmental remediation sites when it is probable that a liability has been incurred and the amount can be reasonably estimated. The amount of the liability is based on our best estimate or the low end of a range of reasonably possible exposure for investigation, cleanup, and monitoring costs to be incurred. Estimated remediation costs are not discounted to present value as the timing of payments cannot be reasonably estimated. We may be able to recover a portion of the remediation costs from insurers or other third parties. Such recoveries are recorded when realization of the claim for recovery is deemed probable.

Cash and Cash Equivalents

Cash and cash equivalents consist of highly liquid instruments, such as commercial paper, time deposits, and other money market instruments, which have original maturities of three months or less. We aggregate our cash balances by bank where conditions for right of set-off are met, and reclassify any negative balances, consisting mainly of uncleared checks, to Accounts payable. Negative balances reclassified to Accounts payable were $132 and $209 at December 31, 2011 and 2010.

Inventories

Inventoried costs on commercial aircraft programs and long-term contracts include direct engineering, production and tooling and other non-recurring costs, and applicable overhead, which includes fringe benefits, production related indirect and plant management salaries and plant services, not in excess of estimated net realizable value. To the extent a material amount of such costs are related to an abnormal event or are fixed costs not appropriately attributable to our programs or contracts, they are expensed in the current period rather than inventoried. Inventoried costs include amounts relating to programs and contracts with long-term production cycles, a portion of which is not expected to be realized within one year. Included in inventory for federal government contracts is an allocation of allowable costs related to manufacturing process reengineering.

Commercial aircraft programs inventory includes deferred production costs. Deferred production costs represent actual costs incurred for production of early units that exceed the estimated average cost of all units in the program accounting quantity. Higher production costs are experienced at the beginning of a new or derivative airplane program. Units produced early in a program require substantially more effort (labor and other resources) than units produced later in a program because of volume efficiencies and the effects of learning. We expect that these deferred costs will be fully recovered when all units included in the accounting quantity are delivered as the expected unit cost for later deliveries is below the estimated average cost of all units in the program.

The determination of net realizable value of long-term contract costs is based upon quarterly reviews that estimate costs to be incurred to complete all contract requirements. When actual contract costs and the estimate to complete exceed total estimated contract revenues, a loss provision is recorded. The determination of net realizable value of commercial aircraft program costs is based upon quarterly program reviews that estimate revenue and cost to be incurred to complete the program accounting quantity. When estimated costs to complete exceed estimated program revenues to go, a program loss provision is recorded in the current period for the estimated loss on all undelivered units in the accounting quantity.

Used aircraft purchased by the Commercial Airplanes segment and general stock materials are stated at cost not in excess of net realizable value. See 'Aircraft Valuation' within this Note for a discussion of our valuation of used aircraft. Spare parts inventory is stated at lower of average unit cost or market. We review our commercial spare parts and general stock materials quarterly to identify impaired inventory, including excess or obsolete inventory, based on historical sales trends, expected production usage, and the size and age of the aircraft fleet using the part. Impaired inventories are charged to Cost of products in the period the impairment occurs.

Included in inventory for commercial aircraft programs are amounts paid or credited in cash, or other consideration to certain airline customers, that are referred to as early issue sales consideration. Early issue sales consideration is recognized as a reduction to revenue when the delivery of the aircraft under contract occurs. If an airline customer does not perform and take delivery of the contracted aircraft, we believe that we would have the ability to recover amounts paid. However, to the extent early issue sales consideration exceeds advances and is not considered to be otherwise recoverable, it would be written off in the current period.

We net advances and progress billings on long-term contracts against inventory in the Consolidated Statements of Financial Position. Advances and progress billings in excess of related inventory are reported in Advances and billings in excess of related costs.

Precontract Costs

We may, from time to time, incur costs to begin fulfilling the statement of work under a specific anticipated contract that we are still negotiating with a customer. If we determine it is probable that we will be awarded the specific anticipated contract, then we capitalize the precontract costs we incur, excluding start-up costs which are expensed as incurred. Capitalized precontract costs are included in Inventories, net of advances and progress billings, in the accompanying Consolidated Statements of Financial Position. Should the contract not be awarded or otherwise determined to no longer be probable of award, the capitalized costs would be written off.

.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost, including applicable construction-period interest, less accumulated depreciation and are depreciated principally over the following estimated useful lives: new buildings and land improvements, from 10 to 40 years; and new machinery and equipment, from 3 to 20 years. The principal methods of depreciation are as follows: buildings and land improvements, 150% declining balance; and machinery and equipment, sum-of-the-years' digits. Capitalized internal use software is included in Other assets and amortized using the straight line method over five years. We periodically evaluate the appropriateness of remaining depreciable lives assigned to long-lived assets, including assets that may be subject to a management plan for disposition.

Long-lived assets held for sale are stated at the lower of cost or fair value less cost to sell. Long-lived assets held for use are subject to an impairment assessment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the carrying value is no longer recoverable based upon the undiscounted future cash flows of the asset, the amount of the impairment is the difference between the carrying amount and the fair value of the asset.

Asset Retirement Obligations

We record all known asset retirement obligations for which the liability's fair value can be reasonably estimated, including certain asbestos removal, asset decommissioning and contractual lease restoration obligations. Recorded amounts are not material.

We also have known conditional asset retirement obligations, such as certain asbestos remediation and asset decommissioning activities to be performed in the future, that are not reasonably estimable due to insufficient information about the timing and method of settlement of the obligation. Accordingly, these obligations have not been recorded in the Consolidated Financial Statements. A liability for these obligations will be recorded in the period when sufficient information regarding timing and method of settlement becomes available to make a reasonable estimate of the liability's fair value. In addition, there may be conditional asset retirement obligations that we have not yet discovered (e.g. asbestos may exist in certain buildings but we have not become aware of it through the normal course of business), and therefore, these obligations also have not been included in the Consolidated Financial Statements.

Goodwill and Other Acquired Intangibles

Goodwill and other acquired intangible assets with indefinite lives are not amortized, but are tested for impairment annually and when an event occurs or circumstances change such that it is more likely than not that an impairment may exist. Our annual testing date is April 1.

We test goodwill for impairment by first comparing the carrying value of net assets to the fair value of the related operations. If the fair value is determined to be less than carrying value, a second step is performed to compute the amount of the impairment. In this process, a fair value for goodwill is estimated, based in part on the fair value of the operations, and is compared to its carrying value. The shortfall of the fair value below carrying value represents the amount of goodwill impairment.

Indefinite-lived intangibles consist of brand and tradenames acquired in business combinations. We test these intangibles for impairment by comparing their carrying value to current projections of discounted cash flows attributable to the brand and tradenames. Any excess carrying value over the amount of discounted cash flows represents the amount of the impairment.

Our finite-lived acquired intangible assets are amortized on a straight-line basis over their estimated useful lives as follows: developed technology, from 4 to 14 years; product know-how, from 3 to 30 years; customer base, from 3 to 19 years; distribution rights, from 3 to 30 years; and other, from 1 to 32 years. We evaluate the potential impairment of finite-lived acquired intangible assets whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the carrying value is no longer recoverable based upon the undiscounted future cash flows of the asset, the amount of the impairment is the difference between the carrying amount and the fair value of the asset.

Investments

Time deposits are held-to-maturity investments that are carried at cost.

The equity method of accounting is used to account for investments for which we have the ability to exercise significant influence, but not control, over an investee. Significant influence is generally deemed to exist if we have an ownership interest in the voting stock of an investee of between 20% and 50%.

We classify investment income and loss on our Consolidated Statements of Operations based on whether the investment is operating or non-operating in nature. Operating investments align strategically and are integrated with our operations. Earnings from operating investments, including our share of income or loss from equity method investments, dividend income from certain cost method investments, and any impairments or gain/loss on the disposition of these investments, are recorded in Income from operating investments, net. Non-operating investments are those we hold for non-strategic purposes. Earnings from non-operating investments, including interest and dividends on marketable securities, and any impairments or gain/loss on the disposition of these investments are recorded in Other income/(expense), net.

Derivatives

All derivative instruments are recognized in the financial statements and measured at fair value regardless of the purpose or intent of holding them. We use derivative instruments to principally manage a variety of market risks. For derivatives designated as hedges of the exposure to changes in fair value of the recognized asset or liability or a firm commitment (referred to as fair value hedges), the gain or loss is recognized in earnings in the period of change together with the offsetting loss or gain on the hedged item attributable to the risk being hedged. The effect of that accounting is to include in earnings the extent to which the hedge is not effective in achieving offsetting changes in fair value. For our cash flow hedges, the effective portion of the derivative's gain or loss is initially reported in Shareholders' equity (as a component of Accumulated other comprehensive loss) and is subsequently reclassified into earnings in the same period or periods during which the hedged forecasted transaction affects earnings. The ineffective portion of the gain or loss of a cash flow hedge is reported in earnings immediately. We also hold certain instruments for economic purposes that are not designated for hedge accounting treatment. For these derivative instruments, the changes in their fair value are also recorded in earnings immediately.

Aircraft Valuation

Used aircraft under trade-in commitments and aircraft under repurchase commitments In conjunction with signing a definitive agreement 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. Additionally, we have entered into contingent repurchase commitments with certain customers wherein we agree to repurchase the Sale Aircraft at a specified price, generally 10 to 15 years after delivery of the Sale Aircraft. Our repurchase of the Sale Aircraft is contingent upon a future, mutually acceptable agreement for the sale of additional new aircraft. If we execute an agreement for the sale of additional new aircraft, and if the customer exercises its right to sell the Sale Aircraft to us, a contingent repurchase commitment would become a trade-in commitment. Our historical experience is that contingent repurchase commitments infrequently become trade-in commitments.

All trade-in commitments at December 31, 2011 and 2010 were solely attributable to Sale Aircraft and did not originate from contingent repurchase commitments. Exposure related to trade-in commitments may take the form of:

(1) adjustments to revenue for the difference between the contractual trade-in price in the definitive agreement and our best estimate of the fair value of the trade-in aircraft as of the date of such agreement, which would be recorded in Inventory and recognized upon delivery of the Sale Aircraft, and/or

(2) charges to cost of products for adverse changes in the fair value of trade-in aircraft that occur subsequent to signing of a definitive agreement for Sale Aircraft but prior to the purchase of the used trade-in aircraft. Estimates based on current aircraft values would be included in Accrued liabilities.

The fair value of trade-in aircraft is determined using aircraft-specific data such as model, age and condition, market conditions for specific aircraft and similar models, and multiple valuation sources. This process uses our assessment of the market for each trade-in aircraft, which in most instances begins years before the return of the aircraft. There are several possible markets in which we continually pursue opportunities to place used aircraft. These markets include, but are not limited to, the resale market, which could potentially include the cost of long-term storage; the leasing market, with the potential for refurbishment costs to meet the leasing customer's requirements; or the scrap market. Trade-in aircraft valuation varies significantly depending on which market we determine is most likely for each aircraft. On a quarterly basis, we update our valuation analysis based on the actual activities associated with placing each aircraft into a market. This quarterly valuation process yields results that are typically lower than residual value estimates by independent sources and tends to more accurately reflect results upon the actual placement of the aircraft.

Used aircraft acquired by the Commercial Airplanes segment are included in Inventories at the lower of cost or market as it is our intent to sell these assets. To mitigate costs and enhance marketability, aircraft may be placed on operating lease. While on operating lease, the assets are included in Customer financing.

Assets under operating lease, assets held for sale or re-lease and collateral underlying receivables Customer financing includes operating lease equipment, notes receivables, and sales-type/finance leases. Sales-type/finance leases are treated as receivables, and allowances for losses are established as necessary.

We assess the fair value of the assets we own, including equipment under operating leases, assets held for sale or re-lease, and collateral underlying receivables, to determine if their fair values are less than the related assets' carrying values. Differences between carrying values and fair values of sales-type/finance leases and notes and other receivables, as determined by collateral value, are considered in determining the allowance for losses on receivables.

We use a median calculated from published collateral values from multiple third-party aircraft value publications based on the type and age of the aircraft to determine the fair value of aircraft. Under certain circumstances, we apply judgment based on the attributes 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 outside publications.

Impairment review for assets under operating leases and held for sale or re-lease We evaluate for impairment assets under operating lease or assets held for sale or re-lease when events or changes in circumstances indicate that the expected undiscounted cash flow from the asset may be less than the carrying value. We use various assumptions when determining the expected undiscounted cash flow, including our intentions for how long we will hold an asset subject to operating lease before it is sold, the expected future lease rates, lease terms, residual value of the asset, periods in which the asset may be held in preparation for a follow-on lease, maintenance costs, remarketing costs and the remaining economic life of the asset. We record assets held for sale at the lower of carrying value or fair value less costs to sell.

When we determine that impairment is indicated for an asset, the amount of impairment expense recorded is the excess of the carrying value over the fair value of the asset.

Allowance for losses on customer financing receivables We record the potential impairment of customer financing receivables in our portfolio in a valuation account, the balance of which is an accounting estimate of probable but unconfirmed losses in the receivables portfolio. The allowance for losses on receivables relates to two components of receivables: (a) receivables that are evaluated individually for impairment and (b) all other receivables.

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 of the receivable agreement, without regard to any subsequent restructurings. Factors considered in assessing collectibility include, but are not limited to, a customer's extended delinquency, requests for restructuring and filings for bankruptcy. We determine a specific impairment allowance based on the difference between the carrying value of the receivable and the estimated fair value of the related collateral we would expect to realize.

We review the adequacy of the allowance attributable to the remaining receivables (after excluding receivables subject to a specific impairment allowance) by assessing both the collateral exposure and the applicable cumulative default rate. Collateral exposure for a particular receivable is the excess of the carrying value of the receivable over the fair value of the related collateral. A receivable with an estimated fair value in excess of the carrying value is considered to have no collateral exposure. The applicable cumulative default rate is determined using two components: customer credit ratings and weighted average remaining contract term. Internally assigned credit ratings, our credit quality indicator, are determined for each customer in the portfolio. Those ratings are updated based upon public information and information obtained directly from our customers.

We have entered into agreements with certain customers that would entitle us to look beyond the specific collateral underlying the receivable for purposes of determining the collateral exposure as described above. Should the proceeds from the sale of the underlying collateral asset resulting from a default condition be insufficient to cover the carrying value of our receivable (creating a shortfall condition), these agreements would, for example, permit us to take the actions necessary to sell or retain certain other assets in which the customer has an equity interest and use the proceeds to cover the shortfall.

Each quarter we review customer credit ratings, published historical credit default rates for different rating categories, and multiple third-party aircraft value publications as a basis to validate the reasonableness of the allowance for losses on receivables. There can be no assurance that actual results will not differ from estimates or that the consideration of these factors in the future will not result in an increase or decrease to the allowance for losses on receivables.

Warranties

In conjunction with certain product sales, we provide warranties that cover factors such as non-conformance to specifications and defects in material and design. The majority of our warranties are issued by our Commercial Airplanes segment. Generally, aircraft sales are accompanied by a three to four-year standard warranty for systems, accessories, equipment, parts, and software manufactured by us or manufactured to certain standards under our authorization. These warranties are included in the programs' estimate at completion. On occasion we have made commitments beyond the standard warranty obligation to correct fleet-wide major issues of a particular model, resulting in additional accrued warranty expense. Warranties issued by our BDS segments principally relate to sales of military aircraft and weapons hardware and are included in the contract cost estimates. These sales are generally accompanied by a six to twelve-month warranty period and cover systems, accessories, equipment, parts, and software manufactured by us to certain contractual specifications. Estimated costs related to standard warranties are recorded in the period in which the related product sales occur. The warranty liability recorded at each balance sheet date reflects the estimated number of months of warranty coverage outstanding for products delivered times the average of historical monthly warranty payments, as well as additional amounts for certain major warranty issues that exceed a normal claims level. Estimated costs of these additional warranty issues are considered changes to the initial liability estimate.

We provide guarantees to certain commercial airplane customers which include compensation provisions for failure to meet specified aircraft performance targets. We account for these performance guarantees as warranties. The estimated liability for these warranties is based on known and anticipated operational characteristics and forecasted customer operation of the aircraft relative to contractually specified performance targets, and anticipated settlements when contractual remedies are not specified. Estimated payments are recorded as a reduction of revenue at delivery of the related aircraft. We have agreements that require certain suppliers to compensate us for amounts paid to customers for failure of supplied equipment to meet specified performance targets. Claims against suppliers under these agreements are included in Inventories and recorded as a reduction in Cost of products at delivery of the related aircraft. These performance warranties and claims against suppliers are included in the programs' estimate at completion.

Supplier Penalties

We record an accrual for supplier penalties when an event occurs that makes it probable that a supplier penalty will be incurred and the amount is reasonably estimable. Until an event occurs, we fully anticipate accepting all products procured under production-related contracts.

.

Guarantees

We record a liability in Accrued liabilities for the fair value of guarantees that are issued or modified after December 31, 2002. For a residual value guarantee where we received a cash premium, the liability is equal to the cash premium received at the guarantee's inception. For credit and performance guarantees, the liability is equal to the present value of the expected loss. We determine the expected loss by multiplying the creditor's default rate by the guarantee amount reduced by the expected recovery, if applicable, for each future period the credit or performance guarantee will be outstanding. If at inception of a guarantee, we determine there is a probable related contingent loss, we will recognize a liability for the greater of (a) the fair value of the guarantee as described above or (b) the probable contingent loss amount.

Derivative Financial Instruments [Abstract]

Derivative Financial Instruments

Note 18 – Derivative Financial Instruments

Cash Flow Hedges

Our cash flow hedges include foreign currency forward contracts, foreign currency option contracts, commodity swaps, and commodity purchase contracts. We use foreign currency forward and option 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 principally occurring within five years in the future, with certain contracts hedging transactions up to 2021. We use commodity derivatives, such as swaps and fixed-price purchase commitments, to hedge against potentially unfavorable price changes for items used in production. These include commitments to purchase electricity at fixed prices through 2016.

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 BCC interest expense.

Derivative Instruments Not Receiving Hedge Accounting Treatment

We also hold certain derivative instruments, primarily foreign currency forward contracts, for risk management purposes but without electing any form of hedge accounting.

Notional Amounts and Fair Values

The notional amounts and fair values of derivative instruments in the Consolidated Statements of Financial Position as of December 31 were as follows:

	Notional amounts(1)				Other assets						Accrued liabilities
	2011		2010		2011			2010			2011			2010
Derivatives designated as hedging instruments:
Foreign exchange contracts	$	2,536	$	2,001	$	185		$	266		$	(33	)	$	(15	)
Interest rate contracts		388		875		29			24
Commodity contracts		102		144								(112	)		(113	)
Derivatives not receiving hedge accounting treatment:
Foreign exchange contracts		605		646		2			8			(47	)		(58	)
Total derivatives		3,631		3,666		216			298			(192	)		(186	)
Netting arrangements						(61	)		(71	)		61			71
Net recorded balance					$	155		$	227		$	(131	)	$	(115	)

⁽¹⁾  Notional amounts represent the gross contract/notional amount of the derivatives outstanding.

Gains/(losses) associated with our cash flow and undesignated hedging transactions and their effect on other comprehensive loss and Net earnings were as follows:

Years ended December 31,	2011			2010
Effective portion recognized in other comprehensive loss, net of taxes:
Foreign exchange contracts	$	12		$	67
Commodity contracts		(25	)		(30	)
Effective portion reclassified out of Accumulated other comprehensive loss into earnings, net of taxes:
Foreign exchange contracts		42			25
Commodity contracts		(26	)		(16	)
Forward points recognized in Other income/(expense), net:
Foreign exchange contracts		37			(3	)
Undesignated derivatives recognized in Other income/(expense), net:
Foreign exchange contracts	$	(21	)	$	(33	)

Based on our portfolio of cash flow hedges, we expect to reclassify gains of $4 (pre-tax) out of Accumulated other comprehensive loss into earnings during the next 12 months. Ineffectiveness related to our hedges was insignificant for the years ended December 31, 2011 and 2010.

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, expiring November 2016. For 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 December 31, 2011 was $39. At December 31, 2011, there was no collateral posted related to our derivatives.

Note 11 – Other Assets

Sea Launch

At December 31, 2011, 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 October 19, 2009, we filed a Notice of Arbitration with the Stockholm Chamber of Commerce seeking reimbursement from the other Sea Launch partners of the $147 bank guarantee payment. On October 7, 2010, the arbitrator ruled that the Stockholm Chamber of Commerce lacked jurisdiction to hear the matter but did not resolve the merits of our claim. We filed a notice appealing the arbitrator's ruling on January 11, 2011. No legal proceedings have commenced against the partners on the partner loans. We 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 loans made to Sea Launch, we could incur additional pre-tax charges of up to $356.
