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 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-month periodthree- and nine-month periods ended March 31,September 29, 2019, are not necessarily indicative of the results that may be expected for the year ending December 31, 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-monththree- and nine-month periods ended March 31,September 29, 2019, and April 1,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, 2018.
Discontinued Operations, Net of Tax. In the third quarter of 2018, we disposed of certain CSRA operations to address an organizational conflict of interest with respect to services provided to a government customer. In accordance with GAAP, the sale did not result in a gain for financial reporting purposes. However, the sale generated a taxable gain, resulting in tax expense of $13.
Accounting Standards Updates.Updates. Effective January 1, 2019, we adopted Accounting Standards Codification (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 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.
For a discussion ofThere are several other accounting standards that have been issued by the FASB but are not yet effective, referincluding 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 requires a number of changes to the Accounting Standards Updates section in our Annual Reportassessment of credit losses, including the utilization of an expected credit loss model, which requires consideration of a broader range of information 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 Form 10-K for the year ended December 31, 2018. These standards areeffective date of January 1, 2020. We have not expected to have a material impactyet determined the effect of the ASU on our results of operations, financial condition or cash flows.


B. ACQUISITIONS 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.
Purchase Price and


Fair Value of Net Assets Acquired. The cash purchase price totaled $9.7 billion and consisted of the following:
CSRA shares outstanding (in millions)165.4

The pro forma information was prepared by combining our reported historical results with the historical results of CSRA for the pre-acquisition periods. In addition, the reported historical amounts were adjusted for the following items, net of associated tax effects:
During the quarter,The impact of acquisition financing.
The removal of certain CSRA operations we obtained additional information that resulted in adjustmentswere required by a government customer to dispose of to address an organizational conflict of interest with respect to services provided to the estimatedcustomer. 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 values thatvalue 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 material.
We have valued $2.1 billionreflect the realization of acquired intangible assets, which consists of acquired backlog and probable follow-on work and associated customer relationships (contract and program intangible assets), with a weighted-average life of 17 years. The intangible assets are being amortized using an accelerated method, which approximates the pattern of how the economic benefit is expected to be used. Under this method, approximately 50% of the aggregate value of the intangible assets will be amortized within six years ofcost savings or synergies from the acquisition, date.
Goodwill representsand does not reflect what our combined results of operations would have been had the purchase price paid in excess of the fair value of net tangible and intangible assets acquired, and is attributable primarily to expected synergies, economies of scale and the assembled workforce of CSRA. Approximately $490 of this goodwill is deductible for income tax purposes over its remaining tax life.acquisition occurred on January 1, 2017.
Other Acquisitions and Divestitures
In the first threenine months of 2019, we completed the acquisition ofacquired two businesses in our Aerospace segment and a business in each of our Aerospace and Missions Systems segments.segment for a total of $19. In 2018, we acquired five5 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 two2 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. As the purchase prices of these acquisitions were not material for the three-month periods ended March 31, 2019, and April 1, 2018, they are included in other investing activities, net, in the unaudited Consolidated Statement of Cash Flows.
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.
We did not have any divestitures inIn the first threenine months of 2019.2019, 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 Information Technology segment. AsFor the nine-month periods ended September 29, 2019, and September 30, 2018, the proceeds from the sale of the commercial health products businessbusinesses were not material for the three-month period ended April 1, 2018, theyand are included in other investing activities, net, in the unaudited Consolidated Statement of Cash Flows.

C. REVENUE
The majority of our revenue is derived from long-term contracts and programs that can span several years. We account for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers.
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 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 75%72% and 73%74% of our revenue for the three-monththree- and nine-month periods ended March 31,September 29, 2019, and April 1,75% and 76% of our revenue for the three- and nine-month periods ended September 30, 2018, respectively. Substantially all of our revenue in the defense segments 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 25%28% and 27%26% of our revenue for the three-monththree- and nine-month periods ended March 31,September 29, 2019, and April 1,25% and 24%


of our revenue for the three- and nine-month periods ended 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 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 March 31,September 29, 2019, we had $69.2$67.4 billion of remaining performance obligations, which we also refer to as total backlog. We expect to recognize approximately 65%55% of our remaining performance obligations as revenue by year-end 2020, an additional 25%30% by year-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 period 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:

Our segments operate under fixed-price, cost-reimbursement and time-and-materials contracts. Our production contracts are primarily fixed-price. 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 rates 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 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 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


three-month nine-month period ended March 31,September 29, 2019, were not materially impacted by any other 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-monththree- and nine-month periods ended March 31,September 29, 2019, and April 1,September 30, 2018, that was included in the contract liability balance at the beginning of each year was $1.7$1.1 billion and $1.5$4.0 billion, and $875 and $3.5 billion, respectively. This revenue represented primarily the sale of business-jet aircraft.




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 2019 and 2018 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):

* Excludes outstanding options to purchase shares of common stock that had exercise prices in excess of the average market price of our common stock during the period and, therefore, the effect of including these options would be antidilutive. These options totaled 3,9755,270 and 5174,899 for the three-monththree- and nine-month periods ended March 31,September 29, 2019, and April 1,3,447 and 3,043 for the three- and nine-month periods ended 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 March 31,September 29, 2019, or December 31, 2018.
Our financial instruments include cash and equivalents, 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 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 March 31,September 29, 2019, and December 31, 2018, and the basis for determining their fair values:

Our Level 1 assets include investments in publicly traded equity securities valued using quoted prices from the market exchanges. The fair value of our Level 2 assets and liabilities is determined under a market approach using valuation models that incorporate observable inputs such as interest rates, bond yields and quoted prices for similar assets. Our Level 3 assets include direct private equity investments that are measured using inputs unobservable to a marketplace participant.


F. INCOME TAXES
Net Deferred Tax Liability. Our deferred tax assets and liabilities are included in other noncurrent assets and liabilities on the Consolidated Balance Sheet. Our net deferred tax liability consisted of the following:

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% 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 March 31, 2019, 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 2017. 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 March 31,September 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. 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
 March 31, 2019 December 31, 2018
Unbilled revenue$30,497
 $27,908
Advances and progress billings(23,130) (21,332)
Net unbilled receivables$7,367

$6,576

The increase in net unbilled receivables during the three-monthnine-month period ended March 31,September 29, 2019, was due primarily to an international wheeled armored vehicle contract in our Combat Systems segment. At March 31,September 29, 2019, the net unbilled receivable related to this contract was $2.2$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:

The increase in total inventories during the three-monthnine-month period ended March 31,September 29, 2019, was due primarily to the ramp-up in production of the new G600 aircraft in our Aerospace segment,segment. We received both type and production certification from the U.S. Federal Aviation Administration (FAA) for which we are anticipating FAA type certificationthe G600 aircraft in June 2019 and entry into servicedelivered the first G600 aircraft in the third quarter of 2019. The increase in total inventories was also driven by production of initial units of the newly-announced G700 aircraft.

K. SHAREHOLDERS EQUITY
Share Repurchases. Our board of directors from time to time authorizes management’s repurchase of outstanding shares of our common stock on the open market. On December 5, 2018, the board of directors authorized management to repurchase up to 10 million additional shares of the company’s outstanding stock. In the three-monthnine-month period ended March 31,September 29, 2019, we repurchased 0.51.1 million of our outstanding shares for $86.$184. On March 31,September 29, 2019, 76.4 million shares remained authorized by our board of directors for repurchase, approximately 2% of our total shares outstanding. We repurchased 1.22.5 million shares for $257$522 in the three-monthnine-month period ended April 1,September 30, 2018.




Dividends per Share. Our board of directors declared dividends of $1.02 and $0.93$3.06 per share for the three-monththree- and nine-month periods ended March 31,September 29, 2019, and April 1,$0.93 and $2.79 per share for the three- and nine-month periods ended September 30, 2018, respectively. We paid cash dividends of $268$295 and $250$858 for the three-monththree- and nine-month periods ended March 31,September 29, 2019, and April 1,$275 and $801 for the three- and nine-month periods ended September 30, 2018, respectively.

Current-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 $68$232 and $95$280 for the three-monthnine-month periods ended March 31,September 29, 2019, and April 1,September 30, 2018, respectively. This was offset partially by pretax amortization of prior service credit of $5$16 and $12$36 for the three-monthnine-month periods ended March 31,September 29, 2019, and April 1,September 30, 2018, respectively. These AOCL components are included in our net periodic pension and other post-retirement benefit cost. See Note O 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 do not use derivative financial instruments for trading or speculative purposes.
Foreign Currency 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 two-year average maturity of these instruments generally matches the duration of the activities that are at risk.


Interest Rate Risk. Our financial instruments subject to interest rate risk include variable-rate commercial paper and fixed- and floating-rate long-term debt obligations. We entered into derivative financial instruments, specifically interest rate swap contracts, to eliminate our floating-rate interest risk. The interest rate risk associated with our 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 MarchSeptember 29, 2019, and December 31, 2019,2018, we held $673$974 and $963 in cash and equivalents, respectively, but held no marketable securities other than those held in trust to meet some of our obligations under workers’ compensation and non-qualified supplemental executive retirement plans. On March 31,September 29, 2019, and December 31, 2018, these marketable securities totaled $199$194 and $202, respectively, and were reflected at fair value on the unaudited 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 $4.6$4.4 billion and $5.8 billion on March 31,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-monththree- and nine-month periods ended March 31,September 29, 2019, and April 1,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-monththree- and nine-month periods ended March 31,September 29, 2019, and


April 1, 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 March 31,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 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-monththree- and nine-month periods ended March 31,


September 29, 2019, or April 1,September 30, 2018. In addition, the effect of changes in foreign exchange rates on non-U.S. cash balances was not material for the three-monthnine-month periods ended March 31,September 29, 2019, and April 1,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 on 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 $1.3$1.2 billion on March 31,September 29, 2019. In addition, from time to time and in the ordinary course of business, we contractually guarantee the payment or performance of our subsidiaries arising under certain contracts.
Aircraft Trade-ins. In connection with orders for new aircraft in contract backlog, our Aerospace segment 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. Other 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 March 31,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 three-monthnine-month periods ended March 31,September 29, 2019, and April 1,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 aan 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:

BeginningBased 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 2019, we decreased the expected long-term rates of return on assets in our primary U.S. other post-retirement benefit plans by 100 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 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 to be probable based on our backlog and probable follow-on contracts,


we defer the excess in other contract costs in other current assets on the Consolidated Balance Sheet until the cost is allocable to contracts. 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 on the Consolidated Balance Sheet.


P. SEGMENT INFORMATION
We have five5 operating segments,segments: Aerospace, Combat Systems, Information Technology, Mission Systems and Marine Systems. We organize our segments in accordance with the nature of products and services offered. We measure each segment’s profitability based on operating earnings. As a result, we do not allocate net interest, other income and expense items, and income taxes to our segments.

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 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.

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; C4ISR (command,command, control, communications, computers, intelligence, surveillance and reconnaissance)reconnaissance (C4ISR) solutions; and shipbuilding and ship repair.
We operate throughOur company is organized into five operating segments: Aerospace, Combat Systems, Information Technology, Mission Systems 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 2018 Annual Report on Form 10-K and with the unaudited Consolidated Financial Statements included in this Form 10-Q.

DEFENSE BUSINESS ENVIRONMENT
With approximately 65% of our revenue from the U.S. government, government spending levels, particularly defense spending, influence our financial performance. At the start of the government’s new fiscal year (FY) that began on October 1, 2019, the Congress had not passed the FY 2020 defense appropriations bill. On September 27, 2019, a continuing resolution (CR) was signed into law, providing funding for federal agencies at FY 2019 spending levels through 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 necessary in the evaluation of our financial statements and operating results. The following paragraphs explain how we recognize revenue and operating costs in our operating segments. We account for revenue in accordance with Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers.
In the Aerospace segment, we record revenue on contracts for new aircraft when 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 segment’s custom completions of narrow-body and wide-body aircraft and the segment’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 services performed during the period.
The majority of the Aerospace segment’s operating costs relates to new aircraft production on firm orders and consists 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 segment’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 segment’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 segment.
In the defense segments, revenue on long-term government contracts is recognized generally over time as the work progresses, either as products are produced or as services are rendered. 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. 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 segments 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. Higher or lower margins can result from a number of factors, including contract type (e.g., fixed-price/cost-reimbursable) and type of work (e.g., development/production).

Our consolidated revenue increased in the third quarter and first quarternine months of 2019 driven by growth in all of our segments. The growthadditional aircraft deliveries in our ITAerospace segment, higher volume from U.S. military vehicles in our Combat Systems segment and increased U.S. Navy ship construction in our Marine Systems segment. In the first nine months of 2019, 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. There were also significant increases in our Aerospace segment due to additional aircraft deliveries and in our Combat Systems segment due to higher volume from U.S. military vehicle programs.
Operating costs and expenses increased at a greater rate than revenuemargin remained steady in the third quarter of 2019 but declined 90 basis points in the first quarternine months of 2019, resulting in a lower operating margin, due primarily to2019. Both periods were impacted by a less favorable aircraft delivery mix in our Aerospace segment and intangible asset amortization expense froma less favorable contract mix in our Combat Systems segment. The unfavorable impacts of these items were fully offset in the CSRA acquisition.third quarter as a result of ongoing operational performance improvements and cost containment activities across the company.




REVIEW OF OPERATING SEGMENTS
Following is a discussion of operating results and outlook for each of our operating segments. For the Aerospace segment, results are analyzed by specific types of products and services, consistent with how the segment is managed. For the defense segments, the discussion is based on markets and the lines of products and services offered with a supplemental discussion of specific contracts and programs when significant to the results. Additional information regarding our segments can be found in Note P to the unaudited Consolidated Financial Statements in Part I, Item 1.

Aircraft manufacturing 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 new large-cabin G500 aircraft, which entered into service in the third quarter of 2018. TheWe expect deliveries of both of these aircraft to continue to ramp up in the fourth quarter.
In the first nine months of 2019, the increase in aircraft services revenue was driven by higher demand for maintenance work and the acquisition in the second quarter of 2018 of Hawker Pacific, a leading provider of integrated aviation solutions across Asia Pacificthe Asia-Pacific region and the Middle East. We sold four pre-owned aircraft in the first quarter of 2019 compared with one in the prior-year period.
The components of the change in the segment’s operating earnings in the third quarter and first nine months of 2019 are presented below. Operating earnings were up in the quarter over the third quarter of 2019 consisted2018, 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 and completions operating earnings were down due to aimpacted by the shift in the mix of Gulfstream aircraft deliveries toas the G600 was introduced and G500 andproduction increased, bringing the typical lower margin associated with initial units of a new aircraft model. The segment’sshift in the mix was offset by the operating earnings generated from additional deliveries in the current-year periods.
Net G&A/other expenses were impacted favorably by lowerhigher in the first nine months of 2019 compared with the prior-year period as a result of the receipt in the second quarter of 2018 of milestone payments from suppliers under our cost sharing arrangements on aircraft development programs. Overall, R&D expenses. Overall,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 third quarter of 2019.

Corporate operating results in the first nine months of 2018 included one-time transaction-related charges of approximately $45 associated with the costs to complete the CSRA acquisition. 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 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. This amount decreased

In our defense segments, this results in a net expense.an increase in the offset reported in Corporate, as described above. Due to the revised assumptions, we expect minimal income/expense for Corporate in the fourth quarter.

As a percentage of revenue, G&A expenses were 6.2% in the first nine months of2019 compared with 6.6% in the first three months of2019 compared with 7.1% in the first threenine months of 2018.
Interest, Net
Net interest expense was $117$350 in the first threenine months of 2019 compared with $27$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 threenine months of 2019 compared with expense of $21$34 in the first threenine months of 2018. These amounts represent primarily the non-service cost components of pension and other post-retirement benefits, which became a net income item in the first nine months of 2019 versus a net expense in 2018.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 2019 reflects a cumulative adjustment to recognize the resulting increase in expense. Due to the revised assumptions, we expect minimal other income/expense in the fourth quarter.

Discontinued Operations, Net of 2019 comparedTax
Concurrent with 2018.the acquisition 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 customer. In the third quarter of 2018, we sold these operations. In accordance with U.S. generally accepted accounting principles (GAAP), the sale did not result in a gain for financial reporting purposes. However, the sale generated a taxable gain, resulting in tax expense of $13.

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 Aerospace segment ended the firstthird quarter of 2019 with backlog of $12.2 billion, up 7% from $11.4 billion compared with $12.1 billion on December 31, 2018.June 30, 2019.
Orders in the firstthird quarter of 2019 reflected demand across our product and services portfolio.portfolio including orders for all models of Gulfstream aircraft. The segment’s book-to-bill ratio (orders divided by revenue) was 1.4-to-10.7-to-1 in the firstthird quarter of 2019 and exceededapproximately 1-to-1 over the trailing 12 months. We received both type and production certification from the U.S. Federal Aviation Administration (FAA) for the G600 aircraft in June 2019 and delivered the first G600 aircraft in the third quarter of 2019.
Beyond total backlog, estimated potential contract value in the Aerospace segment was $2.1 billion on March 31, 2019, compared with $3.1 billion on December 31, 2018. 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 SEGMENTS
The total backlog in our defense segments 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. The unfunded portion includes the amounts that we believe are likely to 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 segments includes unexercised options associated with existing firm contracts and work awarded on unfunded indefinite delivery, indefinite quantity (IDIQ) 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.

FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES
We ended the firstthird quarter of 2019 with a cash balance of $673, down $290 from$974 compared with $963 at the end of 2018. Our net debt position, defined as debt less cash and equivalents and marketable securities, was $12.9$12.7 billion at the end of the firstthird quarter of 2019 compared with $11.5 billion at the end of 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 threenine months of 2019and2018, as classified on the unaudited Consolidated Statement of Cash Flows in Part I, Item 1.
OPERATING ACTIVITIES
Cash used forWe generated cash from operating activities was $795of $587 in the first threenine months of 2019 compared to $496with $1.1 billion in the same period in 2018. The primary driver of cash inflows in both periods was net earnings. However, 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 segment. For additional information about the growth in our unbilled receivables balance, see Note G to the unaudited Consolidated Financial Statements in Part I, Item 1. Cash flows in the first nine months of 2019 were also affected negatively by net OWC growth in our Aerospace segment driven by our position in the development, production and cash collection cycles of our Gulfstream aircraft models.




Additionally, cash flows in the first nine months of 2018 reflected a discretionary pension plan contribution of $255.
INVESTING ACTIVITIES
Cash used for investing activities was $187$604 in the first threenine months of 2019 compared with $105$10.3 billion in the same period in 2018. Our investing activities include cash paid for capital expenditures and business acquisitions; proceeds from asset sales; and purchases, sales and maturities of marketable securities. The primary usesecurities; and proceeds from asset sales. In the first nine months of cash2018, we acquired three businesses for our investing activities in both periods was capital expenditures.an aggregate of $10 billion, including $9.7 billion for CSRA. Capital expenditures were $181$606 in the first threenine months of 2019 compared with $104$447 in the same period in 20182018. The increase reflects ongoing investments to support growth at our shipyards. We expect capital expenditures to be approximately 3% of revenue in 2019.
FINANCING ACTIVITIES
Cash provided by financing activities was $697$65 in the first threenine months of 2019 compared with cash provided by financing activities of $2$7.3 billion in the same period in 2018. Net cash from financing activities includes proceeds received from debt and commercial paper issuances and employee stock option exercises.payment of dividends. Our financing activities also include repurchases of common stock, payment of dividendsdebt repayments and debt repayments.employee stock option exercises.
On 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 threenine months of 2019, we repurchased 0.51.1 million of our outstanding shares for $86.$184. On March 31,September 29, 2019, 76.4 million shares remained authorized by our board of directors for repurchase, approximately 2% of our total shares outstanding. We repurchased 1.22.5 million shares for $257$522 in the first threenine months of 2018.
On March 6, 2019, our board of directors declared an increased quarterly dividend of $1.02 per share, the 22nd consecutive annual increase. Previously, the board had increased the quarterly dividend to $0.93 per share in March 2018. Cash dividends paid were $268$858 in the first threenine months of 2019 compared with $250$801 in the same period in 2018.
In the first quarterWe received net proceeds of 2018, we issued $2.5 billion of commercial paper in anticipation of the acquisition of CSRA, which was completed on April 3, 2018.
We issued $1 billion of$947 from commercial paper in the first quarternine months of 2019, leaving $1.9resulting in $1.8 billion outstanding on March 31,September 29, 2019. We have $5 billion in committed bank credit facilities to support our commercial paper issuances and for general corporate purposes and working capital needs and to support our commercial paper issuances.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 MEASURE – 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 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 the 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. 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 $68$81 ($0.18)0.22) and $97$220 ($0.25)0.60) for the three-monththree- and nine-month periods ended March 31,September 29, 2019, and April 1,$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-monththree- and nine-month periods ended March 31,September 29, 2019, or April 1,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 forassociated with our operating leases, and (2) significant new disclosures about our leasing activities (see Note N to the unaudited Consolidated Financial Statements in Part 1,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 full discussion of our critical accounting policies, see our Annual Report on Form 10-K for the year ended December 31, 2018. 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 II,I, Item 8 in our Annual Report on Form 10-K for the year ended December 31, 2018. These standards are not expected to have a material impact on our results of operations or cash flows.1.
