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

A. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
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 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 period ended April 2, 2017,1, 2018, are not necessarily indicative of the results that may be expected for the year ending December 31, 2017.2018.
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-month periods ended April 2, 2017,1, 2018, and April 3, 2016.2, 2017.
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, 2016.2017.
Accounting Standards Updates. Since the first quarter of 2016,On January 1, 2018, we have adopted the following accounting standards issued by the Financial Accounting Standards Board (FASB) that have impacted our prior-period financial statements::
Accounting Standards Update (ASU) 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting
Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers
ASU 2015-17, Income Taxes (Topic 740)2016-01, Financial Instruments - Overall (Subtopic 825-10): Balance Sheet ClassificationRecognition and Measurement of Deferred Taxes
See Note QFinancial 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 further discussionequity investments that recognized changes in fair value as a component of each of these accounting standards.

We also adopted ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory,the standard on a modified retrospective basis on January 1, 2017.

There are several new accounting standards that have been issued by the FASB but are not yet effective, including 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. The ASU also allows onlyWe adopted the servicestandard retrospectively on January 1, 2018.

ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.

We intend to adoptadopted the standard on January 1, 2018, and recognized a $614 increase to retained earnings on the effective date of January 1, 2018. We have not yet determined the effect of the ASU on our results of operations, financial condition or cash flows.adoption.
For a discussion of other accounting standards that have been issued by the FASB but are not yet effective, refer to the Accounting Standards Updates section in our Annual Report on Form 10-K for the year ended December 31, 2016.2017.

B. SUBSEQUENT EVENTS
On April 3, 2018, we completed our acquisition of CSRA Inc. (CSRA) for $41.25 per share in cash. The aggregate amount of consideration paid, including amounts to repay CSRA’s due and payable debt and cash out outstanding stock options and restricted stock units of CSRA, was approximately $9.7 billion. This amount was funded by a combination of available cash on hand, a borrowing of $7.5 billion under the 364-day credit facility further described in Note J and proceeds from commercial paper issuances. In addition, approximately $450 was paid to satisfy obligations under CSRA’s accounts receivable purchase agreement.
CSRA is now part of General Dynamics Information Technology (GDIT) in our Information Systems and Technology group. The combination of GDIT and CSRA creates a premier provider of high-tech IT solutions to the government IT market.
The disclosures required by Accounting Standards Codification (ASC) Topic 805 are not included in this Form 10-Q because the initial accounting for the business combination is incomplete.
Additionally, on April 11, 2018, we announced that we had entered into a binding agreement to acquire Hawker Pacific, a leading provider of integrated aviation solutions across Asia Pacific and the Middle East, for $250. The transaction is subject to customary closing conditions, and is expected to be completed in the second quarter of 2018.

C. ACQUISITIONS AND DIVESTITURES, GOODWILL, AND INTANGIBLE ASSETS
Acquisitions and Divestitures. In the first quarter of 2018, we acquired a provider of specialized transmitters and receivers in our Information Systems and Technology group. In 2017, we acquired four businesses for an aggregate of $399: a fixed-base operation (FBO) in our Aerospace group; and a manufacturer of electronics and communications products, a provider of mission-critical support services, and a manufacturer of signal distribution products in our Information Systems and Technology group. As the purchase prices of these


acquisitions were not material for the three-month periods ended April 1, 2018, and April 2, 2017, 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.
In the first quarter of 2018, we completed the sale of a commercial health products business in our Information Systems and Technology group. The proceeds from the sale are included in other investing activities, net, in the unaudited Consolidated Statement of Cash Flows.
Goodwill. The changes in the carrying amount of goodwill by reporting unit were as follows:

Amortization expense was $20 and $19 for the three-month periods ended April 1, 2018, and April 2, 2017, respectively.

D. 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, which we adopted on January 1, 2017, using the retrospective method. See Note Q for further discussion of the adoption, including the impact on our 2016 financial statements.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. A contract’s transaction price is allocated to each distinct performance obligation 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 70 percent73% and 73 percent70% of our revenue for the three-month periods ended April 2, 2017,1, 2018, and April 3, 2016,2, 2017, respectively. Substantially all of our revenue in the defense groups is recognized over time.time because control is transferred continuously to our customers. 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.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 single point in time accounted for 30 percent27% and 27 percent30% of our revenue for the three-month periods ended April 2, 2017,1, 2018, and April 3, 2016,2, 2017, respectively. The majority of our revenue recognized at a point in time is for the manufacture of business-jet aircraft in our Aerospace group. Revenue on these contracts is recognized when the customer acceptsobtains control of the asset, which is generally upon delivery and acceptance by the customer of the fully outfitted aircraft.


On April 2, 2017,1, 2018, we had $60.4$62.1 billion of remaining performance obligations, which we also refer to as total backlog. We expect to recognize approximately 30 percent60% of our remaining performance obligations as revenue in 2017,by 2019, an additional 45 percent25% by 20192021 and the balance thereafter. On December 31, 2017, we had $63.2 billion of remaining performance obligations, and on December 31, 2017, we expected to recognize approximately 40% of these remaining performance obligations as revenue in 2018, an additional 40% by 2020 and the balance thereafter.
Contract Estimates. 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 isare 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, and operating earnings (andand diluted earnings per share) by $72 and $50 ($0.11) for the three-month period ended April 2, 2017, and $68 and $58 ($0.12) for the three-month period ended April 3, 2016, respectively. share as follows:

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, 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, 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 period ended April 2, 2017,1, 2018, were not materially impacted by any other factors.
Revenue recognized forin the three-month periods ended April 2, 2017,1, 2018, and April 3, 2016,2, 2017, that was included in the contract liability balance at the beginning of each year was $1.5 billion and $1.7 billion, and $1.4 billion, respectively, andrespectively. This revenue represented primarily revenue from the sale of business-jet aircraft.

C. ACQUISITIONS AND DIVESTITURES, GOODWILL, AND INTANGIBLE ASSETS
Acquisitions and Divestitures
In the first quarter of 2017, we acquired a fixed-base-operations (FBO) facility in our Aerospace 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. As the purchase prices of these acquisitions are not material, they are included in other investing activities 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 in 2017 or 2016. In 2015, we completed the sale of our axle business in our Combat Systems group. In the first quarter of 2016, we recognized in discontinued operations a final adjustment of $13 to the loss on the sale of this business.
Goodwill

Amortization expense was $19 and $27 for the three-month periods ended April 2, 2017, and April 3, 2016, respectively.

D.E. 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 20172018 and 20162017 due to share repurchases. See Note KL 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):

(b)* Excludes outstanding options to purchase shares of common stock because these optionsthat 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 681517 and 2,948681 for the three-month periods ended April 1, 2018, and April 2, 2017, and April 3, 2016, respectively.

E.F. 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 April 2, 2017,1, 2018, or December 31, 2016.2017.
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 April 2, 2017,1, 2018, and December 31, 2016,2017, and the basis for determining their fair values:

F.G. INCOME TAXES
Income Tax Provision. We calculate our provision for federal, state and international income taxes based on current tax law. Tax reform was enacted on December 22, 2017, and has several key provisions impacting accounting for and reporting of income taxes. The most significant provision reduced the U.S. corporate statutory tax rate from 35% to 21% beginning on January 1, 2018. We recorded the effect of the change in tax law in the fourth quarter of 2017.
Net Deferred Tax Asset.Liability. Our deferred tax assets and liabilities are included in other noncurrent assets and liabilities on the Consolidated Balance Sheet. Our net deferred tax assetliability consisted of the following:


April 2, 2017 December 31, 2016April 1, 2018 December 31, 2017

Deferred tax liability(187) (183)(249) (244)
Net deferred tax asset$300
 $381
Net deferred tax liability$(189) $(169)
Tax Uncertainties. 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 April 2, 2017,1, 2018, 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 2015.2016. 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 April 2, 2017, is1, 2018, 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. In addition, there are no 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.

G.H. 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 shipmentachievement of products or rendering of services.contractual milestones. Unbilled receivables consisted of the following:
April 2, 2017 December 31, 2016April 1, 2018 December 31, 2017
Unbilled revenue$25,979
 $25,543
$22,928
 $21,845
Advances and progress billings(21,422) (21,331)(17,063) (16,605)
Net unbilled receivables$4,557
 $4,212
$5,865
 $5,240
The increase in net unbilled receivables during the three-month period ended April 1, 2018, was due primarily to the timing of billings on large international vehicle contracts in our Combat Systems group.

H.I. 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 of the units 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.
Other contract costs represent amounts that are not currently allocable to government contracts, such as a portion of our estimated workers’ compensation obligations, other insurance-related assessments, pension and other post-retirement benefits, 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. If the backlog in the future does not support the continued deferral of these costs, the profitability of our remaining contracts could be adversely affected.

In the first quarter of 2018, we renewed and increased to $2 billion our$1 billion multi-year committed bank credit facility, which was scheduled to expire in July 2018. The new credit facility expires in March 2023. We have an additional $1 billion multi-year committed bank credit facility that expires in November 2020. We may renew or replace these credit facilities in whole or in part at or prior to their expiration dates.
Also in the first quarter of 2018, we entered into a $7.5 billion, 364-day committed bank credit facility that expires in March 2019. We financed the acquisition of CSRA, in part, by borrowing $7.5 billion under this facility subsequent to the end of the quarter. We intend to issue debt securities in the future to repay in whole or in part the borrowings under this facility. The proceeds from these issuances will automatically reduce the banks commitments under this facility to an amount not less than $2 billion. Following this reduction, our three credit facilities will total $5 billion. Our credit facilities are used for general corporate purposes and working capital needs and support our commercial paper issuances. Our credit facilities are guaranteed by several of our 100%-owned subsidiaries.
On April 1, 2018, $2.5 billion of commercial paper had been issued and remained outstanding with a dollar-weighted average interest rate of 2.097% and original maturities of less than 90 days.


Our fixed-rate notes are fully and unconditionally guaranteed by several of our 100-percent-owned100%-owned subsidiaries. See Note PQ for condensed consolidating financial statements. We have the option to redeem the notes prior to their maturity in whole or in part for the principal plus any accrued but unpaid interest and applicable make-whole amounts.
Fixed-rate notes of $900 mature in November of 2017. As we approach the maturity date of this debt, we will determine whether to repay these notes with cash on hand or refinance the obligation.
On April 2, 2017, we had no commercial paper outstanding, but we maintain the ability to access the commercial paper market in the future. We have $2 billion in committed bank credit facilities for general corporate purposes and working capital needs. These credit facilities include a $1 billion multi-year facility expiring in July 2018 and a $1 billion multi-year facility expiring in November 2020. These facilities are required by credit rating agencies to support our commercial paper issuances. We may renew or replace these credit facilities in whole or in part at or prior to their expiration dates. Our bank credit facilities are guaranteed by several of our 100-percent-owned subsidiaries. We also have an effective shelf registration on file with the SEC that allows us to access the debt markets.
Our financing arrangements contain a number of customary covenants and restrictions. We were in compliance with all covenants and restrictions on April 2, 2017.

K.L. SHAREHOLDERS EQUITY
Share Repurchases. Our board of directors authorizes management’s repurchase of outstanding shares of our common stock on the open market from time to time. On March 1, 2017, the board of directors authorized management to repurchase up to 10 million additional shares of the company’s outstanding stock. In the three-month period ended April 2, 2017,1, 2018, we repurchased 1.91.2 million of our outstanding shares for $355.$257. On April 2, 2017, 13.51, 2018, 6.4 million shares remained authorized by our board of directors for repurchase, approximately 4 percent2% of our total shares outstanding. We repurchased 7.81.9 million shares for $1 billion$355 in the three-month period ended April 3, 2016.2, 2017.
Dividends per Share. Dividends declared per share were $0.84$0.93 and $0.76 $0.84for the three-month periods ended April 2, 2017, 1, 2018, and April 3, 2016,2, 2017, respectively. Cash dividends paid were $230$250 and $215$230 for the three-month periods ended April 2, 2017,1, 2018, and April 3, 20162, 2017, respectively.

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 $85$95 and $83$85 for the three-month periods ended April 2, 2017,1, 2018, and April 3, 2016,2, 2017, respectively. This was offset partially by pretax amortization of prior service credit of $18$12 and $19$18 for the three-month periods ended April 2, 2017,1, 2018, and April 3, 2016,2, 2017, respectively. These AOCL components are included in our net periodic pension and other post-retirement benefit cost. See Note NO for additional details.

L.M. 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 $6.2$4.3 billion in notional forward exchange contracts outstanding on April 2, 2017,1, 2018, and $6.3 billion on December 31, 2016.2017. 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 EF for additional details.
Foreign Currency Risk and Hedging Activities. 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-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-month periods ended April 2, 2017,1, 2018, and April 3, 2016.2, 2017. Net gains and losses reclassified to earnings from OCL were not material to our results of operations for the three-month periods ended April 2, 2017,1, 2018, and April 3, 2016,2, 2017, 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 April 2, 2017,1, 2018, or December 31, 2016.2017.
Interest Rate Risk. Our financial instruments subject to interest rate risk include fixed-rate long-term debt obligations and variable-rate commercial paper. However, the risk associated with these 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 April 2, 2017,1, 2018, we held $2.2$4.3 billion in cash and equivalents, 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 April 1, 2018, and December 31, 2017, these marketable securities totaled $190 and $191, respectively, and were reflected at fair value on the unaudited Consolidated Balance Sheet in other current and noncurrent assets.
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 end-of-period exchange rates, and statements of earnings at average exchange rates for each period. The resulting foreign currency translation adjustments are a component of OCL.
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 negative impact of translating our non-U.S. operations’ revenue into U.S. dollars was not material to our results of operations for the three-month periods ended April 1, 2018, and April 2, 2017, or April 3, 2016.2017. In addition, the effect of changes in foreign exchange rates on non-U.S. cash balances was not material for the three-month periods ended April 2, 2017,1, 2018, and April 3, 2016.2, 2017.

M.N. 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 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. 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 $1.1$1.4 billion on April 2, 2017.1, 2018. In addition, from time to time and in the ordinary course of business, we contractually guarantee the payment or performance obligations of our subsidiaries arising under certain contracts.
Aircraft Trade-ins. In connection with orders for new aircraft in funded contract backlog, our Aerospace group 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. 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.
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-month periods ended April 2, 2017,1, 2018, and April 3, 2016,2, 2017, were as follows:

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. 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 recovery of the cost is considered 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 deferred 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.
It is our policy to fund our defined-benefit retirement plans in a manner that optimizes the tax deductibility and contract recovery of contributions considered within our capital deployment framework. Therefore, we may make discretionary contributions in addition to the required contributions determined in accordance with IRS regulations. In addition to our required contributions of approximately $315 in 2018, as we deploy additional cash resulting from the recent tax reform, we intend to make discretionary contributions, resulting in total pension plan contributions of approximately $550 in 2018.

O.P. BUSINESS GROUP INFORMATION
We operate in four business groups: Aerospace, Combat Systems, Information Systems and Technology, and Marine Systems. We organize our business groups in accordance with the nature of products and services offered. We measure each group’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 business groups.

*ASU 2017-07 requires the non-service cost components of pension and other post-retirement benefit cost (e.g., interest cost) to be reported in other income (expense) in the income statement. In our three defense groups, pension and other post-retirement benefit costs are allocable contract costs. For these groups, we report the offset for the non-service cost components in Corporate operating results consist primarily of stockresults. Stock option expense.

Q. PRIOR-PERIOD FINANCIAL STATEMENTS
Our prior-period financial statements were restated for the adoption of three ASUs that are discussed below.
ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. We adopted ASU 2016-09 in the second quarter of 2016. ASU 2016-09 impacted several aspects of our accounting for share-based payment transactions. The ASU requires that excess tax benefits and tax deficiencies (the difference between the deduction for tax purposes and the compensation cost recognized for financial reporting purposes) be recognized as income tax expense or benefit in the Consolidated Statement of Earnings. Previously, these amounts were recognized directly to shareholders’ equity. While this area of the ASU permits only prospective adoption, because we adopted the standard in the second quarter of 2016, we were required to restate the first-quarter 2016 financial statements to reflect the adoption as of the beginning of the year.
In the Consolidated Statement of Cash Flows, the excess tax benefit from equity-based compensation, previously classified as a financing activity, is now classified as an operating activity. Additionally, cash paid when directly withholding shares on an employee’s behalf for tax withholding purposes is classified as a financing activity. These areas were adopted retrospectively.
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 when the customer accepts 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, control, communications, computers, intelligence, surveillance and reconnaissance) solutions; and shipbuilding and ship repair.
We operate throughOur company is organized into four business groups: Aerospace, Combat Systems, Information Systems and Technology, and Marine Systems. 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 20162017 Annual Report on Form 10-K and with the unaudited Consolidated Financial Statements included in this Form 10-Q.
DEFENSE BUSINESS ENVIRONMENTACQUISITION OF CSRA
WithOn April 3, 2018, we completed our acquisition of CSRA Inc. (CSRA) for $41.25 per share in cash. See Note B to the unaudited Consolidated Financial Statements in Part I, Item 1, for further discussion of the acquisition. CSRA is now part of General Dynamics Information Technology (GDIT) in our Information Systems and Technology group. The combination of GDIT and CSRA creates a premier provider of high-tech IT solutions to the government IT market.
As a result of the CSRA acquisition and the associated impacts (e.g., acquisition financing), we anticipate the following adjustments to our 2018 outlook:
CSRA is expected to add approximately 60 percent$3.6 billion of our revenue fromin 2018 to the U.S. government, our financial performance is impacted by U.S. government spending levels, particularly defense spending. Over the past several years, U.S. defense spending has been mandated by the Budget Control ActInformation Systems and Technology group’s revenue.
After a one-time charge of 2011 (BCA). The BCA establishes spending caps over a 10-year period through 2021.
The fiscal year (FY) 2017 budget request for the DoD totals $589 billion, which includes $524 billionapproximately $80 in the base budget in compliancesecond quarter of 2018 associated with the BCA, as well as $65 billion for overseas contingency operations. The budget request represents a slight increase over FY 2016 spending levels. In December 2016, sincecosts to complete the Congress had not passedacquisition, we expect the FY 2017 defense appropriations bill, a continuing resolution (CR), which funds government agencies at FY 2016 spending levels, was approved through April 28, 2017. To prevent detrimental changes or delaysacquisition to certain government programs,be break even to slightly accretive to our diluted earnings per share in the CR included exceptions that provide funding flexibility and additional appropriations for these programs, including the Columbia-class submarine.
On March 8, 2017, the Housesecond half of Representatives passed the FY 2017 defense appropriations bill, but the Senate has not yet passed the bill as of the filing of this Form 10-Q on April 26, 2017. The current CR has not had a material impact on our results of operations, financial condition or cash flows. The timing of the passage of an appropriations bill remains uncertain. However, if a full-year extension of the CR occurs, it is not expected to have a material impact on our results of operations, financial condition or cash flows.2018.

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 ASCAccounting Standards Codification (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 and backlog have been restated. Customers.
In the Aerospace group, we record revenue on contracts for new aircraft when control is transferred to the customer obtains control of the asset, which is generally whenupon delivery and acceptance by the customer acceptsof the fully outfitted aircraft. Revenue associated with the group’s completions of other original equipment


manufacturers’ (OEMs) aircraft and the group’s services businesses areis 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 of aircraft service activity during the period.
The majority of the Aerospace group’s operating costs relatesrelate to new aircraft production on firm orders and consistsconsist 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’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 large-cabin and mid-cabin aircraft deliveries. Additional factors affecting the group’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.
In the three defense groups, 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 groups 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 scope 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, higher or lower margins can be inherent in the contract type (e.g., fixed-price/cost-reimbursable) or type of work (e.g., development/production).

Lower revenue on our international military vehicle programs was driven by the transition from engineering to production on a major combat-vehicle contract in the Middle East and timing of work to upgrade and modernize LAV III combat vehicles for the Canadian army. These decreases were largely offset by higher volume on the BritishU.K. AJAX armoured fighting vehicles, Piranha 5 wheeled armored vehicles for the Romanian Armed Forces and Danishthe upgrade of light armored personnel carriers programs.

Corporate income totaled $7 in the first quarter of 2018 compared with $5 in the first quarter of 2017. Operating resultsAs discussed in Note A to the unaudited Consolidated Financial Statements in Part I, Item 1, Corporate operating costs are impacted by Accounting Standards Update (ASU) 2017-07. ASU 2017-07 requires the non-service cost components of pension and other post-retirement benefit cost (e.g., interest cost) to be reported in other income (expense) in the income statement. In our three defense groups, pension and other post-retirement benefit costs are allocable contract costs. For these groups, we report the offset for the non-service cost

Our effective tax rate was 24.5 percent16.8% in the first three months of 20172018 compared with 28.3 percent24.5% in the prior-year period. The decrease is due primarily to additionalthe reduction of the U.S. corporate statutory tax benefitsrate from equity-based compensation35% to 21% beginning on January 1, 2018, resulting from the enactment of the Tax Cuts and Jobs Act (tax reform) on December 22, 2017. The effective tax rate in the first three months of 2017 associated with stock option exercises and2018 also included the vestingimpact of restricted stock and restricted stock units. We anticipate a full-year 2017 effectiveexcess tax rate of approximately 28 percent.

BACKLOG AND ESTIMATED POTENTIAL CONTRACT VALUE
Our total backlog, including funded and unfunded portions, was $60.4$62.1 billion at the end of the first quarter of 20172018, compared with $62.2$63.2 billion on December 31, 2016. The funded portion of the backlog grew by approximately $1.5 billion to $53.3 billion, or 88 percent of our total backlog.2017. Our total backlog is equal to our remaining performance obligations under contracts that meet the criteria in ASC Topic 606 as discussed in Note BD 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 $85$87.6 billion on April 2, 2017.1, 2018.

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 group ended the first quarter of 20172018 with backlog of $12.6$12.1 billion compared with $13.2$12.5 billion on December 31, 2016.2017.
Orders in the first quarter of 20172018 reflected good demand across our product and services portfolio. We received orders for all models of in-production Gulfstream aircraft, as well as additionalwith particularly strong first-quarter orders for the ultra-large-cabin G650 aircraft. We continue to progress toward anticipated U.S. Federal Aviation Administration (FAA) type certification and entry into service of the new G500 and G600, aircraft,for which are expected to enter into servicewe received additional orders in 2017 and 2018, respectively.the first quarter of 2018.
Beyond total backlog, estimated potential contract value in the Aerospace group was $1.9 billion on April 2, 20171, 2018, compared with $2.1$2 billion on December 31, 2016.2017. Estimated potential contract value represents primarily options to purchase new aircraft and long-term aircraft services agreements. The value was down slightly in the first quarter of 2017 as customers exercised options to purchase new aircraft.



DEFENSE GROUPS
The total backlog in our three defense groups 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 the customer,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 we 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 groups 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 groups was $47.8$50.1 billion on April 2, 2017, down 2.5 percent from $491, 2018, compared with $50.7 billion on December 31, 2016. However, our funded backlog increased over 5 percent2017. The decrease was due primarily to $40.8 billion, primarily in ourthe Marine Systems group.group as the group continued to perform on significant multi-year contracts. The Combat Systems group achieved a book-to-bill ratio (orders divided by revenue) in our Information Systems and Technology group exceededhigher than one-to-one in the first quarter of 2017, resulting in backlog growth of over $250.2018, driven by a large international armored vehicle order. Estimated potential contract value in our defense groups was $22.7$23.6 billion on April 2, 2017, compared with $22.91, 2018, up 3.4% from $22.8 billion on December 31, 2016.

FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES
We ended the first quarter of 20172018 with a cash balance of $2.2$4.3 billion, down $166up $1.3 billion from the end of 2016.2017. Our net debt position, defined as debt less cash and equivalents and marketable securities, less debt, was $1.7$2.1 billion at the end of the first quarter of 20172018 compared with $1.6 billion$999 at the end of 2016.2017.
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 three months of 2018and2017, as classified on the unaudited Consolidated Statement of Cash Flows in the first three months of 2017and2016.Part I, Item 1.
OPERATING ACTIVITIES
We used cash for operating activities of $496 in the first three months of 2018 compared with cash generated cash from operating activities of $533 in the first three months of 2017 compared with $480 in the same period in 2016.2017. The primary driver of cash flowsinflows in both periods was net earnings. CashHowever, cash flows in the first three months of 20172018 were affected negatively by growth in operating working capital, particularly the timing of billings and collections on large international vehicle contracts in our Aerospace group fromCombat Systems group. Additionally, in both periods, cash flows were affected negatively by the build-up of inventory related to the new G500 and G600 aircraft programs.programs and the liquidation of customer deposits associated with aircraft deliveries in our Aerospace group.


INVESTING ACTIVITIES
Cash used for investing activities was $85$105 in the first three months of 20172018 compared with $11885 in the same period in 20162017. 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 use of cash for investing activities in both periods was capital expenditures. We expect capitalCapital expenditures were $104 in the first three months of approximately 2 percent of revenue2018 compared with $62 in 2017.the same period in 2017 as we deploy additional cash resulting from the recent tax reform to support the growth in our shipyards.
FINANCING ACTIVITIES
Cash used forprovided by financing activities was $606$2 billion in the first three months of 20172018 compared with $1.2 billioncash used for financing activities of $606 in the same period in 20162017. Our financing activities include repurchases of common stock, payment of


dividends and debt repayments. Net cash from financing activities also includes proceeds received from debt and commercial paper issuances and employee stock option exercises.
On March 1, 2017, our board of directors authorized management to repurchase up to 10 million additional shares of the company'scompany’s outstanding stock. In the first three months of 2017,2018, we repurchased approximately 1.91.2 million of our outstanding shares for $355.$257. On April 2, 2017, 13.51, 2018, 6.4 million shares remained authorized by our board of directors for repurchase, approximately 4 percent2% of our total shares outstanding. We repurchased 7.81.9 million shares for $1 billion$355 in the first three months of 2016.2017.
On March 1, 2017,7, 2018, our board of directors declared an increased quarterly dividend of $0.84$0.93 per share, the 20th21st consecutive annual increase. Previously, the board had increased the quarterly dividend to $0.76$0.84 per share in March 2016.2017. Cash dividends paid were $230$250 in the first three months of 20172018 compared with $215$230 in the same period in 2016.2017.
Fixed-rate notesIn the first quarter of $900 mature2018, we took several actions in Novemberanticipation of 2017. As we approach the maturity dateacquisition of this debt, we will determine whether to repay these notes with cash on hand or refinance the obligation. 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.
We had no commercial paper outstandingCSRA, which was completed on April 2, 2017.3, 2018. We renewed and increased to $2 billion our $1 billion multi-year committed bank credit facility, which was scheduled to expire in July 2018. The new credit facility expires in March 2023. We have $2an additional $1 billion inmulti-year committed bank credit facilitiesfacility that remain available, including a $1 billion facility expiring in July 2018 and a $1 billion facility expiringexpires in November 2020. TheseWe may renew or replace these credit facilities in whole or in part at or prior to their expiration dates. We also entered into a $7.5 billion, 364-day committed bank credit facility that expires in March 2019. We financed the acquisition of CSRA, in part, by borrowing $7.5 billion under this facility subsequent to the end of the quarter. We intend to issue debt securities in the future to repay in whole or in part the borrowings under this facility. The proceeds from these issuances will automatically reduce the bank’s commitments under this facility to an amount not less than $2 billion. Following this reduction, our three credit facilities will total $5 billion. Our credit facilities are used for general corporate purposes and working capital needs and are required by credit rating agencies to support our commercial paper issuances. We also have an effective shelf registration
In the first quarter of 2018, we issued $2.5 billion of commercial paper, which remained outstanding on file with the Securities and Exchange Commission that allows us to access the debt markets.April 1, 2018.
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 MN to the unaudited Consolidated Financial Statements in Part I, Item 1. Except as otherwise noted in Note M,N, 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 $97 ($0.25) and $50 ($0.11) and $58 ($0.12) for the three-month periods ended April 2, 2017,1, 2018, and April 3, 2016,2, 2017, respectively. No adjustment on any one contract was material to ourthe unaudited Consolidated Financial Statements for the three-month periods ended April 1, 2018, or April 2, 2017, and April 3, 2016.2017.
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.
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, 2016.2017. 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.

Based on this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, on April 2, 2017,1, 2018, our disclosure controls and procedures were effective.
There were no changes in our internal control over financial reporting that occurred during the quarter ended April 2, 2017,1, 2018, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
The certifications of the company’s Chief Executive Officer and Chief Financial Officer required under Section 302 of the Sarbanes-Oxley Act have been filed as Exhibits 31.1 and 31.2 to this report.

FORWARD-LOOKING STATEMENTS
This quarterly report on Form 10-Q contains forward-looking statements that are based on management’s expectations, estimates, projections and assumptions. Words such as “expects,” “anticipates,” “plans,” “believes,” “scheduled,” “outlook,” “estimates,” “should” and variations of these words and similar expressions are intended to identify forward-looking statements. Examples include projections of revenue, earnings, operating margin, segment performance, cash flows, contract awards, aircraft production, deliveries and backlog. In making these statements we rely on assumptions and analyses based on our experience and perception of historical trends, current conditions and expected future developments as well as other factors we consider appropriate under the circumstances. We believe our estimates and judgments are reasonable based on information available to us at the time.

These statements are not guarantees of future performance and involve risks and uncertainties that are difficult to predict. Therefore, actual future results and trends may differ materially from what is forecast in forward-looking statements due to a variety of factors, including, without limitation, the risk factors discussed in Item 1A of our Annual Report on Form 10-K. These factors include:
general U.S. and international political and economic conditions;
decreases in U.S. government defense spending or changing priorities within the defense budget;
termination or restructuring of government contracts due to unilateral government action;


differences in anticipated and actual program performance, including the ability to perform under long-term, fixed-price contracts within estimated costs, and performance issues with key suppliers and subcontractors;
expected recovery on contract claims and requests for equitable adjustment;
changing customer demand or preferences for business aircraft, including the effects of economic conditions on the business-aircraft market;
potential for changing prices for energy and raw materials; and
the status or outcome of legal and/or regulatory proceedings.
All forward-looking statements speak only as of the date of this report or, in the case of any document incorporated by reference, the date of that document. All subsequent written and oral forward-looking statements attributable to General Dynamics or any person acting on our behalf are qualified by the cautionary statements in this section. We do not undertake any obligation to update or publicly release any revisions to forward-looking statements to reflect events, circumstances or changes in expectations after


the date of this report. These factors may be revised or supplemented in subsequent reports on SEC Forms 10-Q and 8-K.
