NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
(Dollars in millions, except per-share amounts or unless otherwise noted)


A. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization. General Dynamics is a global aerospace and defense company that offers a broad portfolio of products and services in business aviation; combat vehicles, weapons systems and munitions; information technology (IT) services; command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR) solutions; and shipbuilding and ship repair.
Basis of Consolidation and Classification. The unaudited Consolidated Financial Statements include the accounts of General Dynamics Corporation and our wholly owned and majority-owned subsidiaries. We eliminate all inter-company balances and transactions in the unaudited Consolidated Financial Statements. Some prior-year amounts have been reclassified among financial statement accounts or disclosures to conform to the current-year presentation.
Consistent with industry practice, we classify assets and liabilities related to long-term contracts as current, even though some of these amounts may not be realized within one year.
Further discussion of our significant accounting policies is contained in the other notes to these financial statements.
Interim Financial Statements. The unaudited Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. These rules and regulations permit some of the information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) to be condensed or omitted.
Our fiscal quarters are typically 13 weeks in length. Because our fiscal year ends on December 31, the number of days in our first and fourth quarters varies slightly from year to year. Operating results for the three- and nine-month periods ended October 1, 2017,September 29, 2019, are not necessarily indicative of the results that may be expected for the year ending December 31, 2017.2019.
The unaudited Consolidated Financial Statements contain all adjustments that are of a normal recurring nature necessary for a fair presentation of our results of operations and financial condition for the three- and nine-month periods ended October 1, 2017,September 29, 2019, and October 2, 2016.September 30, 2018.
These unaudited Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2016.2018.
Discontinued Operations.Operations, Net of Tax. In 2013, we settled litigation with the U.S. Navy related to the terminated A-12 aircraft contract in the company’s former tactical military aircraft business. In connection with the settlement, we released some rights to reimbursement of costs on ships under contract at our Bath, Maine, shipyard. As we progressed through the shipbuilding process, we determined that the cost associated with this settlement was greater than anticipated. Therefore, in the third quarter of 2016,2018, we recognizeddisposed of certain CSRA operations to address an $84 loss, netorganizational conflict of tax,interest with respect to adjust the previously-recognized settlement value.
services provided to a government customer. In 2015, we completedaccordance with GAAP, the sale of our axle businessdid not result in the Combat Systems group. In the first nine months of 2016, we recognized a final adjustment of $13 to the loss ongain for financial reporting purposes. However, the sale generated a taxable gain, resulting in tax expense of the business.$13.
Accounting Standards Updates. OnUpdates. Effective January 1, 2017,2019, we adopted the following accounting standards issued by the Financial Accounting Standards Board (FASB) that have impacted our prior-period financial statements:


Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers
Accounting Standards Update (ASU) 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes
See Note Q for further discussion of each of these accounting standards.
We also adopted ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, on January 1, 2017. We recognized the cumulative effect of this standard as a $3 decrease to retained earnings on the date of adoption. ASU 2016-16 requires recognition of the current and deferred income tax effects of an intra-entity asset transfer, other than inventory, when the transfer occurs, as opposed to former GAAP, which required companies to defer the income tax effects of intra-entity asset transfers until the asset was sold to an outside party. The income tax effects of intra-entity inventory transfers will continue to be deferred until the inventory is sold.
There are several new accounting standards that have been issued by the FASB but are not yet effective, including the following:
ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. Specific to our business, ASU 2016-01 requires equity investments to be measured at fair value with changes in fair value recognized in net income. The ASU eliminates the available-for-sale classification for equity investments that recognized changes in fair value as a component of other comprehensive income. We intend to adopt the standard on a modified retrospective basis with a cumulative-effect adjustment to the Consolidated Balance Sheet on the effective date of January 1, 2018. We do not expect the adoption of the ASU to have a material effect on our results of operations, financial condition or cash flows.
ASU 2016-02, Leases (Topic 842). ASU 2016-02842, Leases. ASC Topic 842 requires the recognition of lease rights and obligations as assets and liabilities on the balance sheet. Previously, lessees were not required to recognize on the balance sheet assets and liabilities arising from operating leases. As we elected the cumulative-effect adoption method, prior-period information has not been restated.


The standard provided several optional practical expedients for use in transition. We elected to use what the Financial Accounting Standards Board (FASB) has deemed the “package of practical expedients,” which allowed us not to reassess our previous conclusions about lease identification, lease classification and the accounting treatment for initial direct costs. We did not elect the practical expedient pertaining to the use of hindsight.
The most significant effects of the standard on our Consolidated Financial Statements are (1) the recognition of new right-of-use assets and lease liabilities on our Consolidated Balance Sheet for our operating leases, and (2) significant new disclosures about our leasing activities (see Note N). On January 1, 2019, we recognized operating lease liabilities and right-of-use assets of $1.4 billion based on the present value of the remaining lease payments over the lease term. The adoption did not result in a cumulative-effect adjustment to retained earnings. The new standard did not have a material impact on our results of operations, financial condition or cash flows.
There are several other accounting standards that have been issued by the FASB but are not yet effective, including Accounting Standards Update (ASU) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 significantly changes how entities account for credit losses for financial assets and certain other instruments, including trade receivables and contract assets, that are not measured at fair value through net income. The ASU also requires disclosurea number of keychanges to the assessment of credit losses, including the utilization of an expected credit loss model, which requires consideration of a broader range of information about leasing arrangements.to estimate expected credit losses over the entire lifetime of the asset, including losses where probability is considered remote. Additionally, the standard requires the estimation of lifetime expected losses for trade receivables and contract assets that are classified as current. We intend to adopt the standard on the effective date of January 1, 2019, using the modified retrospective method of adoption. We are currently evaluating our population of leased assets in order to assess the impact of the ASU on our lease portfolio, and designing and implementing new processes and controls. Until this effort is completed, we cannot determine the effect of the ASU on our results of operations, financial condition or cash flows.
ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 is intended to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the Consolidated Statement of Cash Flows by providing guidance on eight specific cash flow issues. We intend to adopt the standard retrospectively on the effective date of January 1, 2018. We do not expect the adoption of the ASU to have a material effect on our cash flows.
ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. ASU 2017-07 requires the service cost component of net benefit cost to be reported separately from the other components of net benefit cost in the income statement. We expect the standard to increase our 2016 and 2017 operating earnings by $10 and $45, respectively, due to the reclassification of the non-service cost components of net benefit cost, and to decrease other income by the same amounts, with no impact to net earnings in either period. The ASU also allows only the service cost component of net benefit cost to be eligible for


capitalization. We do not expect this area of the ASU to have a material effect on our results of operations, financial condition or cash flows. We intend to adopt the standard on the effective date of January 1, 2018.
ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. ASU 2017-12 is intended to simplify hedge accounting by better aligning an entity’s financial reporting for hedging relationships with its risk management activities. The ASU also simplifies the application of the hedge accounting guidance. ASU 2017-12 is effective on January 1, 2019, with early adoption permitted. For cash flow hedges existing at the adoption date, the standard requires adoption on a modified retrospective basis with a cumulative-effect adjustment to the Consolidated Balance Sheet as of the beginning of the year of adoption. The amendments to presentation guidance and disclosure requirements are required to be adopted prospectively.2020. We have not yet determined the effect of the ASU on our results of operations, financial condition or cash flows, nor have we selected a transition date.flows.


B. REVENUEACQUISITIONS AND DIVESTITURES, GOODWILL, AND INTANGIBLE ASSETS
CSRA Acquisition
On April 3, 2018, we acquired 100% of the outstanding shares of CSRA Inc. (CSRA) for $41.25 per share in cash plus the assumption of outstanding net debt. CSRA is a provider of IT solutions to the defense, intelligence and federal civilian markets and is included in our Information Technology segment.

Pro Forma Information. The following pro forma information presents our consolidated revenue is derivedand earnings from long-term contractscontinuing operations as if the acquisition of CSRA and programs that can span several years. We account for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers, which we adoptedthe related financing transactions had occurred on January 1, 2017, using2017:

The pro forma information was prepared by combining our reported historical results with the retrospective method. See Note Qhistorical results of CSRA for further discussionthe pre-acquisition periods. In addition, the reported historical amounts were adjusted for the following items, net of associated tax effects:
The impact of acquisition financing.
The removal of certain CSRA operations we were required by a government customer to dispose of to address an organizational conflict of interest with respect to services provided to the customer. We completed the sale of these operations in the third quarter of 2018.
The removal of CSRA’s historical pre-acquisition intangible asset amortization expense and debt-related interest expense.
The impact of intangible asset amortization expense assuming our estimate of fair value was applied on January 1, 2017.
The payment of acquisition-related costs assuming they were incurred on January 1, 2017.


The pro forma information does not reflect the realization of expected cost savings or synergies from the acquisition, and does not reflect what our combined results of operations would have been had the acquisition occurred on January 1, 2017.
Other Acquisitions and Divestitures
In the first nine months of 2019, we acquired two businesses in our Aerospace segment and a business in our Missions Systems segment for a total of $19. In 2018, we acquired 5 businesses in addition to the acquisition of CSRA for approximately $400: Hawker Pacific, a leading provider of integrated aviation solutions across Asia Pacific and the Middle East, and 2 fixed-base operation (FBO) businesses in our Aerospace segment; a maintenance and service provider for the German Army and other international customers in our Combat Systems segment; and a provider of specialized transmitters and receivers in our Mission Systems segment.
The operating results of these acquisitions have been included with our reported results since the respective closing dates. The purchase prices of the adoption, includingacquisitions have been allocated to the impactestimated fair value of net tangible and intangible assets acquired, with any excess purchase price recorded as goodwill.
In the first nine months of 2019, we completed the sale of a business in our Information Technology segment that was classified as held for sale on the Consolidated Balance Sheet on December 31, 2018. In 2018, we completed the sale of a commercial health products business during the first quarter and the sale of a public-facing contact-center business during the fourth quarter in our 2016 financial statements.Information Technology segment. For the nine-month periods ended September 29, 2019, and September 30, 2018, the proceeds from the sale of businesses were not material and are included in other investing activities, net, in the unaudited Consolidated Statement of Cash Flows.

C. REVENUE
Performance Obligations. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in ASC Topic 606.for revenue. A contract’s transaction price is allocated to each distinct performance obligation within that contract and recognized as revenue when, or as, the performance obligation is satisfied. The majority of our contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and is, therefore, not distinct. Some of our contracts have multiple performance obligations, most commonly due to the contract covering multiple phases of the product lifecycle (development, production, maintenance and support). For contracts with multiple performance obligations, we allocate the contract’s transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. The primary method used to estimate standalone selling price is the expected cost plus a margin approach, under which we forecast our expected costs of satisfying a performance obligation and then add an appropriate margin for that distinct good or service.
Contract modifications are routine in the performance of our contracts. Contracts are often modified to account for changes in the contract specifications or requirements. In most instances, contract modifications are for goods or services that are not distinct and, therefore, are accounted for as part of the existing contract.
Our performance obligations are satisfied over time as work progresses or at a point in time. Revenue from products and services transferred to customers over time accounted for 70%72% and 74% of our revenue for the three- and nine-month periods ended October 1, 2017,September 29, 2019, and 72%75% and 71%76% of our revenue for the three- and nine-month periods ended October 2, 2016,September 30, 2018, respectively. Substantially all of our revenue in the defense groupssegments is recognized over time, because control is transferred continuously to our customers. Typically, revenue is recognized over time using costs incurred to date relative to total estimated costs at completion to measure progress toward satisfying our performance obligations. Incurred cost represents work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. Contract costs include labor, material, overhead and, when appropriate, G&A expenses.


Revenue from goods and services transferred to customers at a point in time accounted for 30%28% and 26% of our revenue for the three- and nine-month periods ended October 1, 2017,September 29, 2019, and 28%25% and 29% 24%


of our revenue for the three- and nine-month periods ended October 2, 2016,September 30, 2018, respectively. The majority of our revenue recognized at a point in time is for the manufacture of business-jet aircraft in our Aerospace group.segment. Revenue on these contracts is recognized when the customer obtains control of the asset, which is generally upon delivery and acceptance by the customer of the fully outfitted aircraft.
On October 1, 2017,September 29, 2019, we had $63.9$67.4 billion of remaining performance obligations, which we also refer to as total backlog. We expect to recognize approximately 50%55% of our remaining performance obligations as revenue by 2018,year-end 2020, an additional 30% by 2020year-end 2022 and the balance thereafter. On December 31, 2018, we had $67.9 billion of remaining performance obligations, at which time we expected to recognize approximately 45% of these remaining performance obligations as revenue in 2019, an additional 35% by year-end 2021 and the balance thereafter.
Contract Estimates. The majority of our revenue is derived from long-term contracts and programs that can span several years. Accounting for long-term contracts and programs involves the use of various techniques to estimate total contract revenue and costs. For long-term contracts, we estimate the profit on a contract as the difference between the total estimated revenue and expected costs to complete a contract and recognize that profit over the life of the contract.
Contract estimates are based on various assumptions to project the outcome of future events that often span several years. These assumptions include labor productivity and availability; the complexity of the work to be performed; the cost and availability of materials; the performance of subcontractors; and the availability and timing of funding from the customer.
The nature of our contracts gives rise to several types of variable consideration, including claims and award and incentive fees. We include in our contract estimates additional revenue for submitted contract modifications or claims against the customer when we believe we have an enforceable right to the modification or claim, the amount can be estimated reliably and its realization is probable. In evaluating these criteria, we consider the contractual/legal basis for the claim, the cause of any additional costs incurred, the reasonableness of those costs and the objective evidence available to support the claim. We include award or incentive fees in the estimated transaction price when there is a basis to reasonably estimate the amount of the fee. These estimates are based on historical award experience, anticipated performance and our best judgment at the time. Because of our certainty in estimating these amounts, they are included in the transaction price of our contracts and the associated remaining performance obligations.
As a significant change in one or more of these estimates could affect the profitability of our contracts, we review and update our contract-related estimates regularly. We recognize adjustments in estimated profit on contracts under the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to date on a contract is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance are recognized using the adjusted estimate. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, we recognize the total loss in the quarterperiod it is identified.


The impact of adjustments in contract estimates on our operating earnings can be reflected in either operating costs and expenses or revenue. The aggregate impact of adjustments in contract estimates increased our revenue, operating earnings and diluted earnings per share as follows:

Under these contracts, we agree to perform a specific scope of work for a fixed amount. Contracts for research, engineering, repair and maintenance, and other services are typically cost-reimbursement or time-and-materials. Under cost-reimbursement contracts, the customer reimburses contract costs incurred and pays a fixed, incentive or award-based fee. These fees are determined by our ability to achieve targets set in the contract, such as cost, quality, schedule and performance. Under time-and-materials contracts, the customer pays a fixed hourly rate for direct labor and generally reimburses us for the cost of materials.
Each of these contract types presents advantages and disadvantages. Typically, we assume more risk with fixed-price contracts. However, these types of contracts offer additional profits when we complete the work for less than originally estimated. Cost-reimbursement contracts generally subject us to lower risk. Accordingly, the associated base fees are usually lower than fees earned on fixed-price contracts. Under time-and-materials contracts, our profit may vary if actual labor-hour costsrates vary significantly from the negotiated rates. Also, because these contracts can provide little or no fee for managing material costs, the content mix can impact profitability.

Contract Balances. The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities) on the Consolidated Balance Sheet. In our defense groups,segments, amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals (e.g., biweekly or monthly) or upon achievement of contractual milestones. Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. However, we sometimes receive advances or deposits from our customers, particularly on our international contracts, before revenue is recognized, resulting in contract liabilities. These assets and liabilities are reported on the Consolidated Balance Sheet on a contract-by-contract basis at the end of each reporting period. In our Aerospace group,segment, we generally receive deposits from customers upon contract execution and upon achievement of contractual milestones. These deposits are liquidated when revenue is recognized. Changes in the contract asset and liability balances during the nine-month period ended October 1, 2017,September 29, 2019, were not materially impacted by any other factors.factors except for the delays in payment on an international wheeled armored vehicle contract in our Combat Systems segment, which contributed to growth in contract assets as further discussed in Note G.
Revenue recognized for the three- and nine-month periods ended October 1, 2017,September 29, 2019, and October 2, 2016,September 30, 2018, that was included in the contract liability balance at the beginning of each year was $982 and $3.9$1.1 billion and $911$4.0 billion, and $3.7$875 and $3.5 billion, respectively. This revenue represented primarily the sale of business-jet aircraft.


C. ACQUISITIONS, GOODWILL AND INTANGIBLE ASSETS
Acquisitions. In the first nine months of 2017, we acquired three businesses for an aggregate of $364: a fixed-base-operations (FBO) facility in our Aerospace group, and a manufacturer of electronics and communications products and a provider of mission-critical support services and technology solutions in our Information Systems and Technology group. In 2016, we acquired an aircraft management and charter


services provider in our Aerospace group and a manufacturer of unmanned underwater vehicles (UUVs) in our Information Systems and Technology group for an aggregate of $56.
The operating results of these acquisitions have been included with our reported results since the respective closing dates. The purchase prices of the acquisitions have been allocated to the estimated fair value of net tangible and intangible assets acquired, with any excess purchase price recorded as goodwill.
Goodwill. The changes in the carrying amount of goodwill by reporting unit for the nine-month period ended October 1, 2017, were as follows:

Amortization expense was $19 and $57 for the three- and nine-month periods ended October 1, 2017, and $20 and $70 for the three- and nine-month periods ended October 2, 2016.


D. EARNINGS PER SHARE
We compute basic earnings per share (EPS) using net earnings for the period and the weighted average number of common shares outstanding during the period. Basic weighted average shares outstanding have decreased in 20172019 and 20162018 due to share repurchases. See Note K for further discussion of our share repurchases. Diluted EPS incorporates the additional shares issuable upon the assumed exercise of stock options and the release of restricted stock and restricted stock units (RSUs).


Basic and diluted weighted average shares outstanding were as follows (in thousands):

These options totaled 1,8505,270 and 1,4494,899 for the three- and nine-month periods ended October 1, 2017,September 29, 2019, and 4,6223,447 and 4,0803,043 for the three- and nine-month periods ended October 2, 2016,September 30, 2018, respectively.


E. FAIR VALUE
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between marketplace participants. Various valuation approaches can be used to determine fair value, each requiring different valuation inputs. The following hierarchy classifies the inputs used to determine fair value into three levels:
Level 1 - quoted prices in active markets for identical assets or liabilities;
Level 2 - inputs, other than quoted prices, observable by a marketplace participant either directly or indirectly; and
Level 3 - unobservable inputs significant to the fair value measurement.
We did not have any significant non-financial assets or liabilities measured at fair value on October 1, 2017,September 29, 2019, or December 31, 2016.2018.
Our financial instruments include cash and equivalents, and other investments, accounts receivable and payable, marketable securities held in trust and other investments, short- and long-term debt, and derivative financial instruments. The carrying values of cash and equivalents and accounts receivable and payable and short-term debt on the unaudited Consolidated Balance Sheet approximate their fair value. The following tables present the fair values of our other financial assets and liabilities on October 1, 2017,September 29, 2019, and December 31, 2016,2018, and the basis for determining their fair values:

Tax Uncertainties. We participate in the Internal Revenue Service (IRS) Compliance Assurance Process (CAP), a real-time audit of our consolidated federal corporate income tax return. The IRS has examined our consolidated federal income tax returns through 2017 and is currently reviewing our 2018 tax year.


For all periods open to examination by tax authorities, we periodically assess our liabilities and contingencies based on the latest available information. Where we believe there is more than a 50 percent50% chance that our tax position will not be sustained, we record our best estimate of the resulting tax liability, including interest, in the Consolidated Financial Statements. We include any interest or penalties incurred in connection with income taxes as part of income tax expense. The total amount of these tax liabilities on October 1, 2017, was not material to our results of operations, financial condition or cash flows.
We participate in the Internal Revenue Service (IRS) Compliance Assurance Process (CAP), a real-time audit of our consolidated federal corporate income tax return. The IRS has examined our consolidated federal income tax returns through 2016. We do not expect the resolution of tax matters for open years to have a material impact on our results of operations, financial condition, cash flows or effective tax rate.
Based on all known facts and circumstances and current tax law, we believe the total amount of any unrecognized tax benefits on October 1, 2017, isSeptember 29, 2019, was not material to our results of operations, financial condition or cash flows, and if recognized, would not have a material impact on our effective tax rate.flows. In addition, there are no0 tax positions for which it is reasonably possible that the unrecognized tax benefits will vary significantly over the next 12 months, producing, individually or in the aggregate, a material effect on our results of operations, financial condition or cash flows.

Income Tax Provision. The U.S. Treasury Department and the IRS are expected to issue further guidance related to the Tax Cuts and Jobs Act (tax reform) enacted in 2017 that could impact our provision for income taxes in future periods. As a result, we believe it is reasonably possible there may be changes to provisional interpretations and assumptions we made in our initial application of tax reform provisions. We do not expect the impact of any changes to have a material impact on our results of operations, financial condition or cash flows.



G. UNBILLED RECEIVABLES
Unbilled receivables represent revenue recognized on long-term contracts (contract costs and estimated profits) less associated advances and progress billings. These amounts will be billed in accordance with the agreed-upon contractual terms or upon achievement of contractual milestones.terms. Unbilled receivables consisted of the following:
 September 29, 2019 December 31, 2018
Unbilled revenue$33,170
 $27,908
Advances and progress billings(25,093) (21,332)
Net unbilled receivables$8,077

$6,576
 October 1, 2017 December 31, 2016
Unbilled revenue$28,923
 $25,543
Advances and progress billings(23,314) (21,331)
Net unbilled receivables$5,609
 $4,212

The increase in net unbilled receivables during the nine-month period ended October 1, 2017, isSeptember 29, 2019, was due in partprimarily to the timing of billings on a largean international wheeled armored vehicle contract for a Middle Eastern customer in our Combat Systems group.segment. At September 29, 2019, the net unbilled receivable related to this contract was $2.6 billion. Our contract is with the Canadian government, who is selling the vehicles to an international customer. We have experienced delays in payment under the contract. We continue to meet our obligations under the contract and are entitled to payment for work performed. Therefore, we expect to collect the full amount currently outstanding.


H.INVENTORIES
The majority of our inventories are for business-jet aircraft. Our inventories are stated at the lower of cost or net realizable value. Work in process represents largely labor, material and overhead costs associated with aircraft in the manufacturing process and is based primarily on the estimated average unit cost in a production lot. Raw materials are valued primarily on the first-in, first-out method. We record pre-owned aircraft acquired in connection with the sale of new aircraft at the lower of the trade-in value or the estimated net realizable value.


Inventories consisted of the following:

Other contract costs represent amounts that are not currently allocableThe increase in total inventories during the nine-month period ended September 29, 2019, was due primarily to government contracts, such as a portionthe ramp-up in production of the new G600 aircraft in our estimated workers’ compensation obligations, other insurance-related assessments, pensionAerospace segment. We received both type and other post-retirement benefits,production certification from the U.S. Federal Aviation Administration (FAA) for the G600 aircraft in June 2019 and environmental expenses. These costs will become allocable to contracts generally after they are paid. We expect to recover these costs through ongoing business, including existing backlog and probable follow-on contracts. Ifdelivered the backlogfirst G600 aircraft in the future does not supportthird quarter of 2019. The increase in total inventories was also driven by production of initial units of the continued deferral of these costs, the profitability of our remaining contracts could be adversely affected.newly-announced G700 aircraft.

AmountsCurrent-period amounts reclassified out of AOCL related primarily to changes in our retirement plans’ funded status and consisted of pretax recognized net actuarial losses of $255$232 and $249$280 for the nine-month periods ended October 1, 2017,September 29, 2019, and October 2, 2016,September 30, 2018, respectively. This was offset partially by pretax amortization of prior service credit of $53$16 and $56$36 for the nine-month periods ended October 1, 2017,September 29, 2019, and October 2, 2016,September 30, 2018, respectively. These AOCL components are included in our net periodic pension and other post-retirement benefit cost. See Note NO for additional details.


L. DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES
We are exposed to market risk, primarily from foreign currency exchange rates, interest rates, commodity prices and investments. We may use derivative financial instruments to hedge some of these risks as described below. We had $5.2 billion in notional forward exchange contracts outstanding on October 1, 2017, and $6.3 billion on December 31, 2016. We do not use derivative financial instruments for trading or speculative purposes. We recognize derivative financial instruments on the Consolidated Balance Sheet at fair value. See Note E for additional details.
Foreign Currency Risk and Hedging Activities. Risk. Our foreign currency exchange rate risk relates to receipts from customers, payments to suppliers and inter-company transactions denominated in foreign currencies. To the extent possible, we include terms in our contracts that are designed to protect us from this risk. Otherwise, we enter into derivative financial instruments, principally foreign currency forward purchase and sale contracts, designed to offset and minimize our risk. The dollar-weighted three-yeartwo-year average maturity of these instruments generally matches the duration of the activities that are at risk.
We record changes in the fair value of derivative financial instruments in operating costs and expenses in the Consolidated Statement of Earnings or in other comprehensive loss (OCL) within the Consolidated Statement of Comprehensive Income depending on whether the derivative is designated and qualifies for hedge accounting. Gains and losses related to derivative financial instruments that qualify as cash flow hedges are deferred in OCL until the underlying transaction is reflected in earnings. We adjust derivative financial instruments not designated as cash flow hedges to market value each period and record the gain




or loss in the Consolidated Statement of Earnings. The gains and losses on these instruments generally offset losses and gains on the assets, liabilities and other transactions being hedged. Gains and losses resulting from hedge ineffectiveness are recognized in the Consolidated Statement of Earnings for all derivative financial instruments, regardless of designation.
Net gains and losses on derivative financial instruments recognized in earnings, including gains and losses related to hedge ineffectiveness, were not material to our results of operations for the three- and nine-month periods ended October 1, 2017, and October 2, 2016. Net gains and losses reclassified to earnings from OCL were not material to our results of operations for the three- and nine-month periods ended October 1, 2017, and October 2, 2016, and we do not expect the amount of these gains and losses that will be reclassified to earnings during the next 12 months to be material.
We had no material derivative financial instruments designated as fair value or net investment hedges on October 1, 2017, or December 31, 2016.
Interest Rate Risk. Our financial instruments subject to interest rate risk include fixed-ratevariable-rate commercial paper and fixed- and floating-rate long-term debt obligations and variable-rate commercial paper. However, theobligations. We entered into derivative financial instruments, specifically interest rate swap contracts, to eliminate our floating-rate interest risk. The interest rate risk associated with theseour financial instruments is not material.
Commodity Price Risk. We are subject to rising labor and commodity price risk, primarily on long-term, fixed-price contracts. To the extent possible, we include terms in our contracts that are designed to protect us from these risks. Some of the protective terms included in our contracts are considered derivative financial instruments but are not accounted for separately, because they are clearly and closely related to the host contract. We have not entered into any material commodity hedging contracts but may do so as circumstances warrant. We do not believe that changes in labor or commodity prices will have a material impact on our results of operations or cash flows.
Investment Risk. Our investment policy allows for purchases of fixed-income securities with an investment-grade rating and a maximum maturity of up to five years. On October 1, 2017,September 29, 2019, and December 31, 2018, we held $2.7 billion$974 and $963 in cash and equivalents, respectively, but held no marketable securities.securities other than those held in trust to meet some of our obligations under workers’ compensation and non-qualified supplemental executive retirement plans. On September 29, 2019, and December 31, 2018, these marketable securities totaled $194 and $202, respectively, and were reflected at fair value on the Consolidated Balance Sheet in other current and noncurrent assets. See Note E for additional details.
Hedging Activities. We had notional forward exchange and interest rate swap contracts outstanding of $4.4 billion and $5.8 billion on September 29, 2019, and December 31, 2018, respectively. These derivative financial instruments are cash flow hedges, and are reflected at fair value on the Consolidated Balance Sheet in other current assets and liabilities. See Note E for additional details.
Changes in fair value (gains and losses) related to derivative financial instruments that qualify as cash flow hedges are deferred in AOCL until the underlying transaction is reflected in earnings. Alternatively, gains and losses on derivative financial instruments that do not qualify for hedge accounting are recorded each period in earnings. All gains and losses from derivative financial instruments recognized in the Consolidated Statement of Earnings are presented in the same line item as the underlying transaction, either operating costs and expenses or interest expense.
Net gains and losses recognized in earnings on derivative financial instruments that do not qualify for hedge accounting were not material to our results of operations for the three- and nine-month periods ended September 29, 2019, and September 30, 2018. Net gains and losses reclassified to earnings from AOCL related to qualified hedges also were not material to our results of operations for the three- and nine-month periods ended September 29, 2019, and September 30, 2018, and we do not expect the amount of these gains and losses that will be reclassified to earnings during the next 12 months to be material.
We had no material derivative financial instruments designated as fair value or net investment hedges on September 29, 2019, or December 31, 2018.
Foreign Currency Financial Statement Translation. We translate foreign currency balance sheets from our international businesses’ functional currency (generally the respective local currency) to U.S. dollars at the end-of-period exchange rates, and statements of earnings at the average exchange rates for each period. The resulting foreign currency translation adjustments are a component of OCL.AOCL.
We do not hedge the fluctuation in reported revenue and earnings resulting from the translation of these international operations’ results into U.S. dollars. The impact of translating our non-U.S. operations’ revenue into U.S. dollars was not material to our results of operations for the three- and nine-month periods ended October 1, 2017, and October 2, 2016.


September 29, 2019, or September 30, 2018. In addition, the effect of changes in foreign exchange rates on non-U.S. cash balances was not material for the nine-month periods ended October 1, 2017,September 29, 2019, and October 2, 2016.September 30, 2018.


M. COMMITMENTS AND CONTINGENCIES
Litigation
In 2015, Electric Boat Corporation, a subsidiary of General Dynamics Corporation, received a Civil Investigative Demand from the U.S. Department of Justice regarding an investigation of potential False Claims Act violations relating to alleged failures of Electric Boat’s quality system with respect to allegedly non-conforming parts purchased from a supplier. In 2016, Electric Boat was made aware that it is a defendant


in a lawsuit related to this matter which had been filed under seal in U.S. district court. Also in 2016, the Suspending and Debarring Official for the U.S. Department of the Navy issued a Show Cause Letter to Electric Boat requesting that Electric Boat respond to the official’s concerns regarding Electric Boat’s oversight and management with respect to its quality assurance systems for subcontractors and suppliers. Electric Boat responded to the Show Cause Letter and has been engaged in discussions with the U.S. government.
In the third quarter of 2019, the Department of Justice declined to intervene in the qui tam action, noting that its investigation continues, and the court unsealed the relator’s complaint. Given the current status of these matters, we are unable to express a view regarding the ultimate outcome or, if the outcome is adverse, to estimate an amount or range of reasonably possible loss. Depending on the outcome of these matters, there could be a material impact on our results of operations, financial condition and cash flows.
Additionally, various other claims and legal proceedings incidental to the normal course of business are pending or threatened against us. These other matters relate to such issues as government investigations and claims, the protection of the environment, asbestos-related claims and employee-related matters. The nature of litigation is such that we cannot predict the outcome of these other matters. However, based on information currently available, we believe any potential liabilities in these other proceedings, individually or in the aggregate, will not have a material impact on our results of operations, financial condition or cash flows.
Environmental
We are subject to and affected by a variety of federal, state, local and foreign environmental laws and regulations. We are directly or indirectly involved in environmental investigations or remediation at some of our current and former facilities and third-party sites that we do not own but where we have been designated a Potentially Responsible Party (PRP) by the U.S. Environmental Protection Agency or a state environmental agency. Based on historical experience, we expect that a significant percentage of the total remediation and compliance costs associated with these facilities will continue to be allowable contract costs and, therefore, recoverable under U.S. government contracts.
As required, we provide financial assurance for certain sites undergoing or subject to investigation or remediation. We accrue environmental costs when it is probable that a liability has been incurred and the amount can be reasonably estimated. Where applicable, we seek insurance recovery for costs related to environmental liabilities. We do not record insurance recoveries before collection is considered probable. Based on all known facts and analyses, we do not believe that our liability at any individual site, or in the aggregate, arising from such environmental conditions will be material to our results of operations, financial condition or cash flows. We also do not believe that the range of reasonably possible additional loss beyond what has been recorded would be material to our results of operations, financial condition or cash flows.


Other
Government Contracts. As a government contractor, we are subject to U.S. government audits and investigations relating to our operations, including claims for fines, penalties, and compensatory and treble damages. We believe the outcome of such ongoing government audits and investigations will not have a material impact on our results of operations, financial condition or cash flows.
In the performance of our contracts, we routinely request contract modifications that require additional funding from the customer. Most often, these requests are due to customer-directed changes in the scope of work. While we are entitled to recovery of these costs under our contracts, the administrative process with our customer may be protracted. Based uponon the circumstances, we periodically file requests for equitable adjustment (REAs) that are sometimes converted into claims. In some cases, these requests are disputed by our customer. We believe our outstanding modifications, REAs and other claims will be resolved without material impact to our results of operations, financial condition or cash flows.
Letters of Credit and Guarantees. In the ordinary course of business, we have entered into letters of credit, bank guarantees, surety bonds and other similar arrangements with financial institutions and insurance


carriers totaling approximately $1.2 billion on October 1, 2017.September 29, 2019. In addition, from time to time and in the ordinary course of business, we contractually guarantee the paymentspayment or performance of our subsidiaries arising under certain contracts.
Aircraft Trade-ins. In connection with orders for new aircraft in funded contract backlog, our Aerospace groupsegment has outstanding options with some customers to trade in aircraft as partial consideration in their new-aircraft transaction. These trade-in commitments are generally structured to establish the fair market value of the trade-in aircraft at a date generally 45 or fewer days preceding delivery of the new aircraft to the customer. At that time, the customer is required to either exercise the option or allow its expiration. AnyOther trade-in commitments are structured to guarantee a pre-determined trade-in value. These commitments present more risk in the event of an adverse change in market conditions. In either case, any excess of the pre-established trade-in price above the fair market value at the time the new aircraft is delivered is treated as a reduction of revenue in the new-aircraft sales transaction. As of September 29, 2019, the estimated change in fair market values from the date of the commitments was not material.
Product Warranties. We provide warranties to our customers associated with certain product sales. We record estimated warranty costs in the period in which the related products are delivered. The warranty liability recorded at each balance sheet date is based generally on the number of months of warranty coverage remaining for the products delivered and the average historical monthly warranty payments. Warranty obligations incurred in connection with long-term production contracts are accounted for within the contract estimates at completion. Our other warranty obligations, primarily for business-jet aircraft, are included in other current and noncurrent liabilities on the Consolidated Balance Sheet.
The changes in the carrying amount of warranty liabilities for the nine-month periods ended October 1, 2017,September 29, 2019, and October 2, 2016,September 30, 2018, were as follows:

N. LEASES
We determine at its inception whether an arrangement that provides us control over the use of an asset is a lease. We recognize at lease commencement a right-of-use (ROU) asset and lease liability based on the present value of the future lease payments over the lease term. We have elected not to recognize an ROU asset and lease liability for leases with terms of 12 months or less. Certain of our leases include options to extend the term of the lease for up to 30 years or to terminate the lease within 1 year. When it is reasonably certain that we will exercise the option, we include the impact of the option in the lease term for purposes of determining total future lease payments. As most of our lease agreements do not explicitly state the


discount rate implicit in the lease, we use our incremental borrowing rate on the commencement date to calculate the present value of future payments.
Our leases commonly include payments that are based on the Consumer Price Index (CPI) or other similar indices. These variable lease payments are included in the calculation of the ROU asset and lease liability. Other variable lease payments, such as usage-based amounts, are excluded from the ROU asset and lease liability, and are expensed as incurred. In addition to the present value of the future lease payments, the calculation of the ROU asset also includes any deferred rent, lease pre-payments and initial direct costs of obtaining the lease, such as commissions.
In addition to the base rent, real estate leases typically contain provisions for common-area maintenance and other similar services, which are considered non-lease components for accounting purposes. For our real estate leases, we apply a practical expedient to include these non-lease components in calculating the ROU asset and lease liability. For all other types of leases, non-lease components are excluded from our ROU assets and lease liabilities and expensed as incurred.
Our leases are for office space, manufacturing facilities, and machinery and equipment. Real estate represents over 75% of our lease obligations.
The components of lease costs were as follows:

In 2017,Based on recent market conditions, we decreasedadjusted our assumptions for our non-qualified supplemental retirement plans, and the expected long-term ratethird quarter of return on assets2019 reflects a cumulative adjustment to recognize the resulting increase in our primary U.S. government and commercial pension plans by 75 basis points following an assessment of the historical and expected long-term returns of our various asset classes.expense.
Our contractual arrangements with the U.S. government provide for the recovery of contributions to our pension and other post-retirement benefit plans covering employees working in our defense business groups.segments. For non-funded plans, our government contracts allow us to recover claims paid. Following payment, these recoverable amounts are allocated to contracts and billed to the customer in accordance with the Cost Accounting Standards (CAS) and specific contractual terms. For some of these plans, the cumulative pension and other post-retirement benefit cost exceeds the amount currently allocable to contracts. To the extent we consider recovery of the cost is consideredto be probable based on our backlog and probable follow-on contracts, we defer the excess in other contract costs in inventoryother current assets on the Consolidated Balance Sheet until the cost is allocable to contracts. See Note H for discussion of our other contract costs. For other plans, the amount allocated to contracts and included in revenue has exceeded the plans’ cumulative benefit cost. We have similarly deferred recognition of these excess earnings classifying these deferrals against the plan assets on the Consolidated Balance Sheet.

* Corporate operating results consist primarily ofhave two primary components: pension and other post-retirement benefit income, and stock option expense. We are required to report the non-service cost components of pension and other post-retirement benefit cost (e.g., interest cost) in other income (expense) in the Consolidated





Statement of Earnings. As described in Note O, in our defense segments, pension and other post-retirement benefit costs are recoverable contract costs. Therefore, the non-service cost components are included in the operating results of these segments, but an offset is reported in Corporate.

Q. PRIOR-PERIOD FINANCIAL STATEMENTS
Our prior-period financial statements were restated for the adoption of two ASUs that are discussed below.
ASC Topic 606. We adopted ASC Topic 606 on January 1, 2017, using the retrospective method. The adoption of ASC Topic 606 had two primary impacts on our Consolidated Financial Statements. The impact of adjustments on profit recorded to date is now recognized in the period identified (cumulative catch-up method), rather than prospectively over the remaining contract term. For our contracts for the manufacture of business-jet aircraft, we now recognize revenue at a single point in time when control is transferred to the customer, generally upon delivery and acceptance of the fully outfitted aircraft. Prior to the adoption of ASC Topic 606, we recognized revenue for these contracts at two contractual milestones: when green aircraft were completed and accepted by the customer and when the customer accepted final delivery of the fully outfitted aircraft. The cumulative effect of the adoption was recognized as a decrease to retained earnings of $372 on January 1, 2015.
We applied the standard’s practical expedient that permits the omission of prior-period information about our remaining performance obligations. No other practical expedients were applied.
ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. We adopted ASU 2015-17 on January 1, 2017, using the retrospective method. ASU 2015-17 requires that deferred tax assets and liabilities be classified as noncurrent on the Consolidated Balance Sheet. The adoption of ASU 2015-17 resulted in reclassifications among accounts on the Consolidated Balance Sheet, but had no other impacts on our results of operations, financial condition or cash flows.
The following tables summarize the effects of adopting these accounting standards on our unaudited Consolidated Financial Statements.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS
(Dollars in millions, except per-share amounts or unless otherwise noted)


BUSINESS OVERVIEW
General Dynamics is a global aerospace and defense company that offers a broad portfolio of products and services in business aviation; combat vehicles, weapons systems and munitions; information technology (IT) services and C4ISR (command,services; command, control, communications, computers, intelligence, surveillance and reconnaissance)reconnaissance (C4ISR) solutions; and shipbuilding and ship repair.
We operate through four business groups:Our company is organized into five operating segments: Aerospace, Combat Systems, Information Technology, Mission Systems and Technology, and Marine Systems. We refer to the latter four segments collectively as our defense segments. Our primary customer is the U.S. government, including the Department of Defense (DoD), the intelligence community and other U.S. government customers. We also have significant business with non-U.S. governments and a diverse base of corporate and individual buyers of business-jet aircraft. The following discussion should be read in conjunction with our 20162018 Annual Report on Form 10-K and with the unaudited Consolidated Financial Statements included in this Form 10-Q.
DEFENSE BUSINESS ENVIRONMENT
With approximately 60%65% of our revenue from the U.S. government, our financial performance is impacted by U.S. government spending levels, particularly defense spending. Prior tospending, influence our financial performance. At the U.S.start of the government’s new fiscal year (FY) that began on October 1, 2017,2019, the Congress had not passed the FY 20182020 defense appropriations bill. On September 8, 2017,27, 2019, a continuing resolution (CR), which funds government was signed into law, providing funding for federal agencies at FY 20172019 spending levels was approved through December 8, 2017.November 21, 2019. When the government operates under a CR, newly awarded programs are not funded, which could result in program delays. We do not anticipate that the current CR, or subsequent extensions, will have a material impact on our results of operations, financial condition or cash flows.


RESULTS OF OPERATIONS
INTRODUCTION
An understanding of our accounting practices is important to evaluatenecessary in the evaluation of our financial statements and operating results. The following paragraphs explain how we recognize revenue and operating costs in our business groups. We account for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers, which we adopted on January 1, 2017. As a result of adoption, our prior-period results of operations have been restated.operating segments.
In the Aerospace group,segment, we record revenue on contracts for new aircraft when control is transferred to the customer obtains control of the asset, which is generally upon delivery and acceptance by the customer of the fully outfitted aircraft. Revenue associated with the group’ssegment’s custom completions of other original equipment manufacturers’ (OEMs)narrow-body and wide-body aircraft and the group’ssegment’s services businesses is recognized as work progresses or upon delivery of services. Fluctuations in revenue from period to period result from the number and mix of new aircraft deliveries, progress on aircraft completions, and the level and type of aircraft service activityservices performed during the period.
The majority of the Aerospace group’ssegment’s operating costs relaterelates to new aircraft production on firm orders and consistconsists of labor, material, subcontractor and overhead costs. The costs are accumulated in production lots, recorded in inventory and recognized as operating costs at aircraft delivery based on the


estimated average unit cost in a production lot. While changes in the estimated average unit cost for a production lot impact the level of operating costs, the amount of operating costs reported in a given period is based largely


on the number and type of aircraft delivered. Operating costs in the Aerospace group’ssegment’s completions and services businesses are recognized generally as incurred.
For new aircraft, operating earnings and margin are a function of the prices of our aircraft, our operational efficiency in manufacturing and outfitting the aircraft, and the mix of ultra-large-cabin, large-cabin and mid-cabin aircraft deliveries. Additional factors affecting the group’ssegment’s earnings and margin include the volume, mix and profitability of completions and services work performed, the volume of and market for pre-owned aircraft, and the level of general and administrative (G&A) and net research and development (R&D) costs incurred by the group.segment.
In the three defense groups,segments, revenue on long-term government contracts is recognized generally over time as the work progresses, either as the products are produced or as services are rendered. Typically, revenue is recognized over time using an input measure (e.g., costs incurred to date relative to total estimated costs at completion)completion to measure progress. Operatingprogress toward satisfying our performance obligations. Incurred cost represents work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. Contract costs for the defense groups consist ofinclude labor, material, subcontractor, overhead and, when appropriate, G&A costs and are recognized generally as incurred.expenses. Variances in costs recognized from period to period reflect primarily increases and decreases in production or activity levels on individual contracts. Because costs are used as a measure of progress, year-over-year variances in cost result in corresponding variances in revenue, which we generally refer to as volume.
Operating earnings and margin in the defense groupssegments are driven by changes in volume, performance or contract mix. Performance refers to changes in profitability based on adjustments to estimates at completion on individual contracts. These adjustments result from increases or decreases to the estimated value of the contract, the estimated costs to complete the contract or both. Therefore, changes in costs incurred in the period compared with prior periods do not necessarily impact profitability. It is only when total estimated costs at completion on a given contract change without a corresponding change in the contract value that the profitability of that contract may be impacted. Contract mix refers to changes in the volume of higher- versus lower-margin work. Additionally, higherHigher or lower margins can be inherent in theresult from a number of factors, including contract type (e.g., fixed-price/cost-reimbursable) orand type of work (e.g., development/production).

Our consolidated results for the third quarter of 2017 reflected strong operating performance, with operating earnings over $1 billion and a robust operating margin of 13.9% in the third quarter and 13.8% in the first nine months of 2017.
Revenue was downrevenue increased in the third quarter and first nine months of 20172019 driven by loweradditional aircraft deliveries in our Aerospace segment, higher volume from U.S. military vehicles in our Combat Systems segment and increased U.S. Navy ship construction volume in our Marine Systems group and lower volume across our Information Systems and Technology


group. These decreases were offset partially by higher volume across our Combat Systems group and increased revenue from aircraft deliveries and aircraft services in our Aerospace group.
Operating costs and expenses decreased at a greater rate than revenue in the third quarter and first nine months of 2017 resulting in operating earnings and margin growth compared with the prior-year periods. Operating margin expanded 60 basis points in the third quarter driven primarily by strong program performance and favorable contract mix in our Information Systems and Technology and Combat Systems groups.segment. In the first nine months of 2017, operating2019, the increase in revenue was also driven by the acquisition of CSRA Inc. (CSRA) in our Information Technology segment, which we acquired on April 3, 2018. See Note B to the unaudited Consolidated Financial Statements in Part I, Item 1, for further discussion of the acquisition.
Operating margin expandedremained steady in the third quarter of 2019 but declined 90 basis points due to improved operating performancein the first nine months of 2019. Both periods were impacted by a less favorable aircraft delivery mix in our Aerospace Information Systemssegment and Technology, anda less favorable contract mix in our Combat Systems groups.segment. The unfavorable impacts of these items were fully offset in the third quarter as a result of ongoing operational performance improvements and cost containment activities across the company.

Aircraft manufacturing outfitting and completions revenue increased due primarily to the initial deliveries of the new large-cabin G600 aircraft, which entered into service in the third quarter of 2019, and additional deliveries of the ultra-large-cabin G650 and mid-cabin G280large-cabin G500 aircraft, offset partially by fewer G550 and G450 large-cabinwhich entered into service in the third quarter of 2018. We expect deliveries of both of these aircraft deliveries. Aircraftto continue to ramp up in the fourth quarter.
In the first nine months of 2019, the increase in aircraft services revenue increasedwas driven by higher demand for maintenance


work and the acquisition in the second quarter of 2018 of Hawker Pacific, a fixed-base-operations (FBO) facility in 2017. We had one pre-owned aircraft sale in eachleading provider of integrated aviation solutions across the Asia-Pacific region and the Middle East.
The components of the third-quarter periods and four pre-owned aircraft saleschange in the first nine months of 2017 compared with six in the first nine months of 2016. While we sold the same number of pre-owned aircraft in the third quarter of 2017 compared with the prior-year period, the type of aircraft sold resulted in lower pre-owned aircraft revenue.
The increase in the group’ssegment’s operating earnings in the third quarter and first nine months of 2017 consisted2019 are presented below. Operating earnings were up in the quarter over the third quarter of 2018, which is particularly notable in light of a significant favorable supplier settlement in the third quarter of 2018 that was the primary driver of the following:decrease in operating earnings in the first nine months of 2019.

AircraftIn addition to the supplier settlement, aircraft manufacturing outfitting and completions operating earnings were up due to a favorableimpacted by the shift in the mix of large-cabinGulfstream aircraft deliveries as the G600 was introduced and effective cost containment. R&D expenses (includedG500 production increased, bringing the typical lower margin associated with initial units of a new aircraft model. The shift in the mix was offset by the operating earnings generated from additional deliveries in the current-year periods.

Overall, R&D expenses have been trending downward with the completion of the G500 and G600 aircraft test programs, resulting in lower G&A/other expenses in the G600.
Thethird quarter of 2019. In total, the Aerospace group’ssegment’s operating margin was down 30decreased 270 basis points in the third quarter driven by higher R&D expenses. However, operating margin increased 150and 400 basis points in the first nine months of 20172019 compared with the prior-year period as a favorable aircraft delivery mix and strong performance more than offset the impact of higher R&D expenses.
Outlook
We expect the group’s full-year 2017 revenue to be consistent with our second-quarter estimate of approximately $8 to $8.1 billion. Operating margin is expected to be around 19.6%, also in line with our prior outlook.periods.

Revenue was up across the Combat Systems group in the third quarter and first nine months of 2017. Revenue from U.S. military vehicles increased due primarily to higher volume on the U.S. Army’s StrykerAbrams M1A2 System Enhancement Package Version 3 (SEPv3) tank and new Mobile Protected Firepower (MPF) vehicle programs. Weapons systems and munitions revenue was up due primarily to increased production ofvolume on several products, including bombs and Hydra-70 rocketsartillery for the U.S. government.Army and missile subcomponents. Revenue from international military vehicles increased in the third quarter and first nine months of 2017decreased due to the ramp up in productionlower volume on various wheeled armored vehicle programs and reduced volume on the British Army’s AJAX armouredarmored fighting vehicles program. In the first nine months of 2017, revenue from international military vehicles also increased due to higher volume on the group’s contract to refurbish and upgrade Abrams main battle tanks for the Kingdom of Morocco and several international light armored vehicle (LAV) programs. These increases were offset partially by lower revenue on a large combat-vehicle contract in the Middle Eastprogram as the groupit transitions from engineering to production.

Excluding these charges, Corporate operating results have two primary components: pension and other post-retirement benefit income, and stock option expense.


We are required to report the non-service cost components of pension and other post-retirement benefit cost (e.g., interest cost) in other income (expense) in the prior-year period.Consolidated Statement of Earnings. In our defense segments, pension and other post-retirement benefit costs are recoverable contract costs. Therefore, the non-service cost components are included in the operating results of these segments, but an offset is reported in Corporate.
Based on recent market conditions, we adjusted our assumptions for our non-qualified supplemental retirement plans, and the third quarter of 2019 reflects a cumulative adjustment to recognize the resulting increase in expense.

OTHER FINANCIAL INFORMATION
G&A Expenses
As a percentage of revenue, G&A expenses were 6.2% in the first nine months of2019 compared with 6.6% in the first nine months of2017 compared with 6.2% in the first nine months of 2016. We expect full-year G&A expenses as a percentage of revenue in 2017 to be generally consistent with the first nine months of2017. 2018.
Interest, Net
Net interest expense was $76$350 in the first nine months of 20172019 compared with $68$244 in the prior-year period. The increase iswas due primarily to the impact of financing the CSRA acquisition, including the issuance of $7.5 billion of fixed- and floating-rate notes in the second quarter of 2018. See Note I to the unaudited Consolidated Financial Statements in Part I, Item 1, for additional information regarding our debt obligations, including interest rates.
Other, Net
Net other income was $18 in the first nine months of 2019 compared with expense of $34 in the first nine months of 2018. These amounts represent primarily the non-service cost components of pension and other post-retirement benefits, which became a $500 net increaseincome item in long-term debt beginningthe first nine months of 2019 versus a net expense in the prior-year period. The first nine months of 2018 also included approximately $30 of transaction costs associated with the CSRA acquisition.
Based on recent market conditions, we adjusted our assumptions for our non-qualified supplemental retirement plans, and the third quarter of 2016. We2019 reflects a cumulative adjustment to recognize the resulting increase in expense. Due to the revised assumptions, we expect full-year 2017 net interest minimal other income/expense to be approximately $110.in the fourth quarter.


Provision for Income Tax, Net
Our effective tax rate was 25.8%17.5% in the first nine months of 20172019 compared with 27.9%17.1% in the prior-year period. The decrease is due primarily to additional tax benefits from equity-based compensation in the first


nine months of 2017 associated with stock option exercises and the vesting of restricted stock and restricted stock units and increased international activity. WeFor 2019, we anticipate oura full-year 2017 effective tax rate to be approximately 27%.in the mid-17% range.
Discontinued Operations, Net of Tax
In 2013, we settled litigationConcurrent with the U.S. Navy relatedacquisition of CSRA, we were required by a government customer to dispose of certain CSRA operations to address an organizational conflict of interest with respect to services provided to the terminated A-12 aircraft contract in the company’s former tactical military aircraft business.customer. In connection with the settlement, we released some rights to reimbursement of costs on ships under contract at our Bath, Maine, shipyard. As we progressed through the shipbuilding process, we determined that the cost associated with this settlement was greater than anticipated. Therefore, in the third quarter of 2016,2018, we recognized an $84 loss, net of tax, to adjust the previously-recognized settlement value.

In the first nine months of 2016, we recognized a final adjustment of $13 to the loss ongain for financial reporting purposes. However, the sale generated a taxable gain, resulting in tax expense of the business.$13.


BACKLOG AND ESTIMATED POTENTIAL CONTRACT VALUE
Our total backlog, including funded and unfunded portions, was $63.9$67.4 billion at the end of the third quarter of 2017, up 9.2%2019, down slightly from $58.6$67.7 billion on July 2, 2017.June 30, 2019. Our total backlog is equal to our remaining performance obligations under contracts with customers as discussed in Note BC to the unaudited Consolidated Financial Statements in Part I, Item 1. Our total estimated contract value, which combines total backlog with estimated potential contract value, was $89.7$103 billion on October 1, 2017.September 29, 2019, up 1.1% from $101.9 billion on June 30, 2019.

AEROSPACE
Aerospace funded backlog represents new aircraft and custom completion orders for which we have definitive purchase contracts and deposits from customers. Unfunded backlog consists of agreements to provide future aircraft maintenance and support services. The groupAerospace segment ended the third quarter of 20172019 with backlog of $11.8$11.4 billion compared with $12.2$12.1 billion on July 2, 2017.June 30, 2019.
Orders in the third quarter of 20172019 reflected strong demand across our product and services portfolio. We receivedportfolio including orders for all models of in-production Gulfstream aircraft, as well as additional orders for the G500 and G600 aircraft, which are expected to enter into service in 2018.aircraft. The segment’s book-to-bill ratio (orders divided by revenue) was nearly one-to-one0.7-to-1 in the third quarter of 2019 and approximately 1-to-1 over the trailing 12 months. We received both type and production certification from the U.S. Federal Aviation Administration (FAA) for Gulfstreamthe G600 aircraft in June 2019 and delivered the first G600 aircraft in the third quarter of 2017.2019.
Beyond total backlog, estimated potential contract value in the Aerospace group was $1.9 billion on October 1, 2017, and July 2, 2017. Estimated potential contract value represents primarily options and other agreements with existing customers to purchase new aircraft and long-term aircraft services agreements. On September 29, 2019, estimated potential contract value in the Aerospace segment was $2.1 billion, consistent with June 30, 2019.

On October 21, 2019, we introduced the new G700 aircraft, combining our industry-leading high-speed, ultra-long-range, ultra-long-cabin G650ER aircraft with an expanded cabin, a new high-thrust, high-efficiency engine to optimize performance and our Symmetry Flight Deck – the industry’s most technologically advanced flight deck, which we launched on our new G500 and G600 aircraft. The G700 is expected to enter into service in 2022, following type certification from the FAA and European Aviation Safety Agency. Although the G700 was only recently announced, demand for the next generation aircraft has been solid, and our September 29, 2019, backlog already includes orders associated with the new model.

DEFENSE GROUPSSEGMENTS
The total backlog in our three defense groupssegments represents the estimated remaining sales value of work to be performed under firm contracts. The funded portion of this backlog includes items that have been authorized and appropriated by the U.S. Congress and funded by customers, as well as commitments by international customers that are approved and funded similarly by their governments. We have included in total backlog firm contracts atThe unfunded portion includes the amounts that we believe are likely to receive funding,be funded, but there is no guarantee that future budgets and appropriations will provide the same funding level currently anticipated for a given program.
Estimated potential contract value in our defense groupssegments includes unexercised options associated with existing firm contracts and work awarded on unfunded indefinite delivery, indefinite quantity (IDIQ) contracts and unexercised options associated with existing firm contracts. Contract options in our defense business represent agreements to perform additional work under existing contracts at the election of the customer. We recognize options in backlog when the customer exercises the option and establishes a firm order. For IDIQ contracts, we evaluate the amount of funding we expect to receive and include this amount in our estimated potential contract value. This amount is often less than the total IDIQ contract value, particularly when the contract has multiple awardees. The actual amount of funding received in the future may be higher or lower than our estimate of potential contract value. We recognize options in backlog when the customer exercises the option and establishes a firm order.
Total backlog in our defense groupssegments was $52.1$56 billion on October 1, 2017, up 12.5% from $46.3September 29, 2019, compared with $55.5 billion on July 2, 2017, driven by a $5.1 billion contract awarded by the U.S. Navy to complete the designJune 30, 2019. The Combat Systems, Information Technology and prototype development of the lead Columbia-class submarine. Each of our defense groupsMission Systems segments each achieved a book-to-bill ratio exceeding one-to-onein excess of 1-to-1 in the third quarter of 2017.2019. Estimated potential contract value in our defense segments was $23.8$33.6 billion on October 1, 2017, compared with $22.5September 29, 2019, up 4.4% from $32.2 billion on July 2, 2017.June 30, 2019.

FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES
We ended the third quarter of 20172019 with a cash balance of $2.7 billion, up $388 from$974 compared with $963 at the end of 2016.2018. Our net debt position, defined as debt less cash and equivalents and marketable securities, less debt, was $2.2$12.7 billion at


the end of the third quarter of 20172019 compared with $1.6$11.5 billion at the end of 2016.2018.
We expect to continue to generate funds in excess of our short- and long-term liquidity needs. We believe we have adequate funds on hand and sufficient borrowing capacity to execute our financial and operating strategy. The following is a discussion of our major operating, investing and financing activities in the first nine months of 2019and2018, as classified on the unaudited Consolidated Statement of Cash Flows in the first nine months of 2017and2016.Part I, Item 1.
OPERATING ACTIVITIES
We generated cash from operating activities of $1.9 billion$587 in the first nine months of 20172019 compared with $1.4$1.1 billion in the same period in 2016.2018. The primary driver of cash flowsinflows in both periods was net earnings. CashHowever, cash flows in both periods were affected negatively by growth in operating working capital (OWC), particularly the timing of payments on international armored vehicle contracts in our Combat Systems group duesegment. For additional information about the growth in our unbilled receivables balance, see Note G to the timingunaudited Consolidated Financial Statements in Part I, Item 1. Cash flows in the first nine months of billings on a large contract for a Middle Eastern customer, and2019 were also affected negatively by net OWC growth in our Aerospace group fromsegment driven by our position in the build-updevelopment, production and cash collection cycles of inventory related toour Gulfstream aircraft models.


Additionally, cash flows in the new G500 and G600 aircraft programs andfirst nine months of 2018 reflected a decrease in customer deposits associated with aircraft deliveries.discretionary pension plan contribution of $255.
INVESTING ACTIVITIES
Cash used for investing activities was $584$604 in the first nine months of 20172019 compared with $282$10.3 billion in the same period in 2016.2018. Our investing activities include cash paid for capital expenditures and business acquisitions; purchases, sales and maturities of marketable securities; and proceeds from asset sales. The primary usesIn the first nine months of cash for investing activities in both periods were acquisitions and capital expenditures. In 2017,2018, we acquired three businesses for an aggregate of $364, and in 2016, we acquired two businesses$10 billion, including $9.7 billion for an aggregate of $56.CSRA. Capital expenditures were $273$606 in the first nine months of 20172019 compared with $244$447 in the same period in 2016. We expect capital expenditures between 1% and 2% of revenue in 2017.2018. The increase reflects ongoing investments to support growth at our shipyards.
FINANCING ACTIVITIES
Cash used forprovided by financing activities was $881 million$65 in the first nine months of 20172019 compared with $1.5$7.3 billion in the same period in 2016.2018. Net cash from financing activities includes proceeds received from debt and commercial paper issuances and payment of dividends. Our financing activities also include repurchases of common stock, payment of dividends and debt repayments. Net cash from financing activities also includes proceeds received from debt issuancesrepayments and employee stock option exercises.
On March 1, 2017,December 5, 2018, our board of directors authorized management to repurchase up to 10 million additional shares of the company’s outstanding stock. In the first nine months of 2017,2019, we repurchased approximately 5.91.1 million of our outstanding shares for $1.1 billion.$184. On October 1, 2017, 9.5September 29, 2019, 6.4 million shares remained authorized by our board of directors for repurchase, approximately 3%2% of our total shares outstanding. We repurchased 11.22.5 million shares for $1.5 billion$522 in the first nine months of 2016.2018.
On March 1, 2017,6, 2019, our board of directors declared an increased quarterly dividend of $0.84$1.02 per share, the 20th22nd consecutive annual increase. Previously, the board had increased the quarterly dividend to $0.76$0.93 per share in March 2016.2018. Cash dividends paid were $735$858 in the first nine months of 20172019 compared with $678$801 in the same period in 2016.
In the third quarter of 2017, we issued $1 billion of fixed-rate notes. The proceeds will be used to repay $900 of fixed-rate notes maturing in November of 2017 and for general corporate purposes. In the third quarter of 2016, we repaid $500 of fixed-rate notes on their maturity date with cash on hand and issued $1 billion of fixed-rate notes for general corporate purposes. See Note I to the unaudited Consolidated Financial Statements in Part I, Item 1, for additional information regarding our debt obligations, including scheduled debt maturities and interest rates.2018.
We had noreceived net proceeds of $947 from commercial paper in the first nine months of 2019, resulting in $1.8 billion outstanding on October 1, 2017.September 29, 2019. We have $2$5 billion in committed bank credit facilities that remain available, including a $1 billion facility expiring in July 2018to support our commercial paper issuances and a $1 billion facility expiring in November 2020. These facilities are for general corporate purposes and working capital


needs. We also have an effective shelf registration on file with the Securities and Exchange Commission that allows us to access the debt markets.
In the first nine months of 2018, we issued $7.5 billion of fixed- and floating-rate notes to finance the acquisition of CSRA. Additionally, in the first nine months of 2018, we paid $450 to satisfy obligations under CSRA’s accounts receivable purchase agreement.
Fixed- and floating-rate notes totaling $2.5 billion mature in May 2020. As we approach the maturity date of this debt, we plan to repay these notes using a combination of cash on hand and the issuance of commercial paper. For additional information regarding our debt obligations, including scheduled debt maturities and interest rates, and our credit facilities, see Note I to the unaudited Consolidated Financial Statements in Part I, Item 1.
NON-GAAP FINANCIAL MEASURESMEASURE – FREE CASH FLOW
We emphasize the efficient conversion of net earnings into cash and the deployment of that cash to maximize shareholder returns. As described below, we use free cash flow from operations to measure our performance in these areas. While we believe this metric provides useful information, it is not a defined operating measure under U.S. generally accepted accounting principles (GAAP), and there are limitations associated with its use. Our calculation of this metric may not be completely comparable to similarly titled measures of other


companies due to potential differences in the method of calculation. As a result, the use of this metric should not be considered in isolation from, or as a substitute for, other GAAP measures.
We define free cash flow from operations as net cash provided by operating activities less capital expenditures. We believe free cash flow from operations is a useful measure for investors because it portrays our ability to generate cash from our businesses for purposes such as repaying maturing debt, funding business acquisitions, repurchasing our common stock and paying dividends. We use free cash flow from operations to assess the quality of our earnings and as a key performance measure in evaluating management. The following table reconciles the free cash flow from operations with net cash provided by operating activities, as classified on the unaudited Consolidated Statement of Cash Flows:Flows in Part I, Item 1:

ADDITIONAL FINANCIAL INFORMATION
ENVIRONMENTAL MATTERS AND OTHER CONTINGENCIES
For a discussion of environmental matters and other contingencies, see Note M to the unaudited Consolidated Financial Statements in Part I, Item 1. Except as otherwise noted in Note M, we do not expect our aggregate liability with respect to these matters to have a material impact on our results of operations, financial condition or cash flows.
APPLICATION OF CRITICAL ACCOUNTING POLICIES
Management’s Discussion and Analysis of Financial Condition and Results of Operations is based on ourthe unaudited Consolidated Financial Statements, which have been prepared in accordance with U.S. GAAP. The preparation of financial statements in accordance with GAAP requires that we make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during the reporting period.
Accounting for long-term contracts and programs involves the use of various techniques to estimate total contract revenue and costs. Contract estimates are based on various assumptions to project the outcome of future events that often span several years. We review and update our contract-related estimates regularly. We recognize adjustments in estimated profit on contracts under the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to date on a contract is recognized in the period the adjustment is identified. The aggregate impact of adjustments in contract estimates increased our


operating earnings (and diluted earnings per share) by $103 ($0.22) and $274 ($0.58) for the three- and nine-month periods ended October 1, 2017, and $52 ($0.11) and $169 ($0.35) for the three- and nine-month periods ended October 2, 2016, respectively. No adjustment on any one contract was material to our unaudited Consolidated Financial Statements for the three- and nine-month periods ended October 1, 2017, and October 2, 2016.
Other significant estimates include those related to goodwill and intangible assets, income taxes, pension and other post-retirement benefits, workers’ compensation, warranty obligations, and litigation and other contingencies. We employ judgment in making our estimates, but they are based on historical experience, currently available information and various other assumptions that we believe to be reasonable under the circumstances. These estimates form the basis for making judgments about the carrying values of assets and liabilities that are not readily available from other sources. Actual results may differ from these estimates.
Revenue. Accounting for long-term contracts and programs involves the use of various techniques to estimate total contract revenue and costs. Contract estimates are based on various assumptions to project the outcome of future events that often span several years. We review and update our contract-related estimates regularly. We recognize adjustments in estimated profit on contracts under the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to date on a contract is recognized in the period the adjustment is identified.The aggregate impact of adjustments in contract


estimates increased our operating earnings (and diluted earnings per share) by $81 ($0.22) and $220 ($0.60) for the three- and nine-month periods ended September 29, 2019, and $103 ($0.27) and $283 ($0.75) for the three- and nine-month periods ended September 30, 2018, respectively. No adjustment on any one contract was material to the unaudited Consolidated Financial Statements for the three- and nine-month periods ended September 29, 2019, or September 30, 2018.
Leases. Effective January 1, 2019, we adopted ASC Topic 842, Leases. ASC Topic 842 requires the recognition of lease rights and obligations as assets and liabilities on the balance sheet. Previously, lessees were not required to recognize on the balance sheet assets and liabilities arising from operating leases. As we elected the cumulative-effect adoption method, prior-period information has not been restated. The most significant effects of the standard on our Consolidated Financial Statements are (1) the recognition of new right-of-use assets and lease liabilities on our Consolidated Balance Sheet associated with our operating leases, and (2) significant new disclosures about our leasing activities (see Note N to the unaudited Consolidated Financial Statements in Part I, Item1). On January 1, 2019, we recognized operating lease liabilities and right-of-use assets of $1.4 billion based on the present value of the remaining lease payments over the lease term. The adoption did not result in a cumulative-effect adjustment to retained earnings. The new standard did not have a material impact on our results of operations or cash flows.
CSRA Acquisition. We are required to estimate the fair value of the assets acquired and liabilities assumed in business combinations on the acquisition date, including identified intangible assets. The amount of purchase price paid in excess of the net assets acquired is recorded as goodwill. The fair values are estimated in accordance with the principles of ASC Topic 820, Fair Value Measurement, which defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. The fair values of the net assets acquired are determined primarily using Level 3 inputs (inputs that are unobservable to the market place participant).
The most significant of the fair value estimates is related to long-lived assets, specifically intangible assets subject to amortization. We have valued $2.1 billion of acquired intangible assets in connection with the CSRA acquisition. This amount was determined based primarily on CSRA’s projected cash flows. The projected cash flows include various assumptions, including the timing of work embedded in backlog, success in securing future business, profitability of work, and the appropriate risk-adjusted interest rate used to discount the projected cash flows.
Other. Other significant estimates include those related to goodwill and intangible assets, income taxes, pension and other post-retirement benefits, workers’ compensation, warranty obligations, and litigation and other contingencies. We believe our judgment is applied consistently and produces financial information that fairly depicts our results of operations for all periods presented.

For a discussion of new accounting standards that have been issued by the FASB but are not yet effective, see Note A to the unaudited Consolidated Financial Statements in Part I, Item 1.
