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; ship construction and repair; land combat vehicles, weapons systems and munitions; and technology products and services.
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 (SEC). 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 period ended April 4, 2021, are not necessarily indicative of the results that may be expected for the year ending December 31, 2021.
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 4, 2021, and March 29, 2020.
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, 2020.
Property, Plant and Equipment, Net. Property, plant and equipment (PP&E) is carried at historical cost, net of accumulated depreciation. Net PP&E consisted of the following:
April 4, 2021December 31, 2020
PP&E$10,795 $10,714 
Accumulated depreciation(5,705)(5,614)
PP&E, net$5,090 $5,100

Accounting Standards Updates. There are accounting standards that have been issued by the Financial Accounting Standards Board but are not yet effective. These standards are not expected to have a material impact on our results of operations, financial condition or cash flows.

B. REVENUE
Performance Obligations. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account 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 life cycle (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 80% and 81% of our revenue for the three-month periods ended April 4, 2021, and March 29, 2020, 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 20% and 19% of our revenue for the three-month periods ended April 4, 2021, and March 29, 2020, respectively. Most 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 April 4, 2021, we had $89.6 billion of remaining performance obligations, which we also refer to as total backlog. We expect to recognize approximately 50% of our remaining performance obligations as revenue by year-end 2022, an additional 25% by year-end 2024 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
9


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:
Three Months EndedApril 4, 2021March 29, 2020
Revenue$85 $90 
Operating earnings63 90 
Diluted earnings per share$0.17 $0.25 
No adjustment on any one contract was material to the unaudited Consolidated Financial Statements for the three-month periods ended April 4, 2021, or March 29, 2020.
Revenue by Category. Our portfolio of products and services consists of approximately 10,000 active contracts. The following series of tables presents our revenue disaggregated by several categories.

Total revenue$1,691 $2,246 $1,708 $3,104 $8,749 
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.
11


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 period ended April 4, 2021, were not materially impacted by any other factors.
12


Revenue recognized for the three-month periods ended April 4, 2021, and March 29, 2020, that was included in the contract liability balance at the beginning of each year was $1.5 and $1.2 billion, respectively. This revenue represented primarily the sale of business jet aircraft.

(a)Changes in gross carrying amounts consist primarily of adjustments for write-offs of fully amortized intangible assets, acquired intangible assets and foreign currency translation.
(b)Consists of acquired backlog and probable follow-on work and associated customer relationships.
Amortization expense is included in operating costs and expenses in the Consolidated Statement of Earnings. Amortization expense for intangible assets was $55 and $66 for the three-month periods ended April 4, 2021, and March 29, 2020, respectively.

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 2021 and 2020 due to 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).
13


Basic and diluted weighted average shares outstanding were as follows (in thousands):
Three Months EndedApril 4, 2021March 29, 2020
Basic weighted average shares outstanding284,102 288,569 
Dilutive effect of stock options and restricted stock/RSUs*1,096 1,374 
Diluted weighted average shares outstanding285,198 289,943 
* 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 8,298 and 5,908 for the three-month periods ended April 4, 2021, and March 29, 2020, 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.
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 4, 2021, or December 31, 2020.
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 April 4, 2021, and December 31, 2020, 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, which consist primarily of fixed-income securities, cash flow hedge assets and our fixed-rate notes, 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:
April 4, 2021December 31, 2020
Deferred tax asset$38 $37 
Deferred tax liability(445)(461)

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 2019.
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.
Based on all known facts and circumstances and current tax law, we believe the total amount of any unrecognized tax benefits on April 4, 2021, was not material to our results of operations, financial condition or cash flows. 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. 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:
April 4, 2021December 31, 2020
Unbilled revenue$36,769 $36,657 
Advances and progress billings(28,782)(28,633)
Net unbilled receivables$7,987 $8,024 
On April 4, 2021, and December 31, 2020, net unbilled receivables included $1.9 billion and $2.8 billion, respectively, associated with a large international wheeled armored vehicle contract in our Combat Systems segment. We had experienced delays in payment under the contract in 2018 and 2019, which resulted in the large unbilled receivables balances. In March 2020, we finalized a contract amendment with the customer that included a revised payment schedule. Under the amended contract, we received progress payments of $1 billion in 2020 and $1.1 billion in the first quarter of 2021. Further progress payments will liquidate the net unbilled receivables balance over the next few years.

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.

K. SHAREHOLDERS EQUITY
Share Repurchases. Our board of directors from time to time authorizes management to repurchase outstanding shares of our common stock on the open market. On March 4, 2020, 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 4, 2021, we repurchased 4.6 million of our outstanding shares for $744. On April 4, 2021, 7.7 million shares remained authorized by our board of directors for repurchase, representing 2.7% of our total shares outstanding. We repurchased 3.4 million shares for $501 in the three-month period ended March 29, 2020.
Dividends per Share. Our board of directors declared dividends of $1.19 and $1.10 per share for the three-month periods ended April 4, 2021, and March 29, 2020, respectively. We paid cash dividends of $315 and $295 for the three-month periods ended April 4, 2021, and March 29, 2020, respectively.

Amounts reclassified out of AOCL related primarily to changes in our retirement plans’ funded status and included pretax recognized net actuarial losses and amortization of prior service credit. See Note N for these amounts, which are included in our net periodic pension and other post-retirement benefit cost.

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 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
19


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 4, 2021, and December 31, 2020, we held $1.8 billion and $2.8 billion 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 pension plans. On April 4, 2021, and December 31, 2020, we held marketable securities in trust of $206 and $211, respectively. These marketable securities are reflected at fair value on the Consolidated Balance Sheet in other current and noncurrent assets. See Note E for additional details.
Hedging Activities. We had notional forward exchange and interest rate swap contracts outstanding of $9.1 billion and $9.4 billion on April 4, 2021, and December 31, 2020, 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-month periods ended April 4, 2021, and March 29, 2020. Net gains and losses reclassified to earnings from AOCL related to qualified hedges were also not material to our results of operations for the three-month periods ended April 4, 2021, and March 29, 2020, 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 4, 2021, or December 31, 2020.
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 and earnings into U.S. dollars was not material to our results of operations for the three-month periods ended April 4, 2021, or March 29, 2020. 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 4, 2021, and March 29, 2020.

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 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. In the fourth quarter of 2020, the relator filed a second amended 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.
21


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 billion on April 4, 2021. 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 April 4, 2021, 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.
22


The changes in the carrying amount of warranty liabilities for the three-month periods ended April 4, 2021, and March 29, 2020, were as follows:
Three Months EndedApril 4, 2021March 29, 2020
Beginning balance$660 $619 
Warranty expense26 26 
Payments(40)(12)
Ending balance$646 $633 

N. RETIREMENT PLANS
We provide retirement benefits to eligible employees through a variety of plans:
Defined contribution
Defined benefit
Pension (qualified and non-qualified)
Other post-retirement benefit
For our defined benefit plans, net periodic benefit credit for the three-month periods ended April 4, 2021, and March 29, 2020, consisted of the following:
Pension BenefitsOther Post-retirement Benefits
Three Months EndedApril 4, 2021March 29, 2020April 4, 2021March 29, 2020

Net actuarial loss (gain)103 79  (1)
Prior service credit(5)(4)  
Net periodic benefit credit$(23)$(7)$(2)$(1)
Our contractual arrangements with the U.S. government provide for the recovery of pension and other post-retirement benefit costs related to employees working on government contracts. For these plans, the amount allocated to contracts is determined in accordance with the Cost Accounting Standards and Federal Acquisition Regulation. At this time, cumulative benefit costs exceed the amount allocated to contracts. To the extent we consider recovery of benefit costs 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. To the extent there is a non-service component of net periodic benefit credit for our defined benefit plans, it is reported in other income (expense) in the Consolidated Statement of Earnings.

O. SEGMENT INFORMATION
We have four operating segments: Aerospace, Marine Systems, Combat Systems and Technologies. 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.

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; ship construction and repair; land combat vehicles, weapons systems and munitions; and technology products and services.
Our company is organized into four operating segments: Aerospace, Marine Systems, Combat Systems and Technologies. We refer to the latter three 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 and related services. The following discussion should be read in conjunction with our 2020 Annual Report on Form 10-K and with the unaudited Consolidated Financial Statements included in this Form 10-Q.

BUSINESS ENVIRONMENT
The Coronavirus (COVID-19) pandemic has caused significant disruptions to national and global economies and government activities over the last year. During this time, we have continued to conduct our operations while responding to the pandemic with actions to mitigate adverse consequences to our employees, business, supply chain and customers. While we expect this situation to be temporary, any longer-term impact to our business is currently unknown due to the uncertainty around the pandemic’s duration and its broader impact. For additional information, see the Risk Factors in Part I, Item 1A, and the Business Environment in Part II, Item 7, in our most recent Form 10-K filing.
The United States and some other governments have taken steps to respond to the pandemic and to support economic activity and liquidity in the capital markets. In the United States, the American Rescue Plan Act (ARPA) is the latest legislation to provide relief. ARPA extends through September 30, 2021, the provisions of the Coronavirus Aid, Relief, and Economic Security Act (the CARES Act) that allow agencies to reimburse contractors for payments to covered workers who are prevented from working due to government facility closures or other restrictions. ARPA also includes changes to employer funding requirements for pension plans designed to reduce the amount of required contributions. However, these same provisions reduce the amount of pension costs reimbursable on our U.S. government contracts. As a result, this provision is not expected to have a material impact on our 2021 results of operations and financial condition.
Our Aerospace segment continues to experience the most significant impact from the pandemic. New aircraft deliveries reflect last year’s decision to reduce production rates due to the pandemic. While orders were strong in the quarter, additional new aircraft revenue growth is dependent on the continued improvement of the large economies of the world and the return of international travel. As air travel has increased, demand for aircraft services has improved, but remains modestly below pre-pandemic levels. Our U.S. government business continues to experience some disruption from the COVID-19 pandemic, particularly in our Technologies segment due to select customer site closures and limited access to some customer sites. The Review of Operating Segments includes additional information on the first-quarter results for each of our segments.

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 and the terminology we use to describe our operating results.
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. Aircraft mix can also refer to the stage of program maturity for our aircraft models. A new aircraft model typically has lower margins in its initial production lots, and then margins generally increase as we realize efficiencies in the production process. 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.
26


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 (or vice versa) 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). Contract mix can also refer to the stage of program maturity for our long-term production contracts. New long-term production contracts typically have lower margins initially, and then margins generally increase as we achieve learning curve improvements or realize other cost reductions.

Operating margin decreased 70 basis points in the first quarter of 2021 due primarily to mark-to-market adjustments related to aircraft that were in the G500 flight test program and a less favorable mix in aircraft deliveries in the Aerospace segment.

REVIEW OF OPERATING SEGMENTS
Following is a discussion of operating results 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 O to the unaudited Consolidated Financial Statements in Part I, Item 1.

Operating Results
The increase in the Aerospace segment’s revenue in the first quarter of 2021 consisted of the following:
Aircraft manufacturing$207 
Aircraft services and completions(11)
Total increase $196 
Aircraft manufacturing revenue increased on additional deliveries of large-cabin G500 and G600 aircraft. The first quarter of 2020 was impacted by delayed aircraft deliveries caused by COVID-related quarantine and travel restrictions. In the second quarter of 2020, in response to the pandemic, we lowered our aircraft production rate, which impacts 2021 deliveries. The full impact of the adjusted production rate will be reflected in our second quarter deliveries, after which we expect steady revenue growth as scheduled customer deliveries increase in the third and fourth quarters. Aircraft services and completions revenue was down slightly from the first quarter of 2020 as increased Gulfstream services revenue was more than offset by decreased fixed-base operator (FBO) and other aircraft services, which remain below pre-pandemic levels.
The change in the segment’s operating earnings in the first quarter of 2021 consisted of the following:
Aircraft manufacturing$(43)
Aircraft services and completions21 
G&A/other expenses
Total decrease$(20)
Aircraft manufacturing operating earnings were down in the first quarter of 2021 due primarily to a less favorable mix in aircraft deliveries. Operating earnings were also impacted by mark-to-market adjustments related to aircraft that were in the G500 flight test program. This decrease was offset partially by increased aircraft services and completions operating earnings due to favorable cost performance and mix of aircraft services. In total, the Aerospace segment’s operating margin decreased 250 basis points in the first quarter of 2021 compared with the prior-year period.

U.S. Navy ship engineering, repair and other services
Commercial ship construction(33)
Total increase$237 
Revenue from U.S. Navy ship construction was up in the first quarter of 2021 due to increased volume on Block V of the Virginia-class submarine program, the Columbia-class submarine program and the Expeditionary Sea Base (ESB) auxiliary support ship program. The Marine Systems segment’s operating margin decreased 10 basis points in the first quarter of 2021, reflecting the shift in mix to early work on new submarine programs with the typical lower initial profit rates.

U.S. military vehicles(12)
Total increase $112 
Revenue from international military vehicles increased in the first quarter of 2021 due primarily to higher volume on contracts to produce 8x8 and 6x6 vehicles for a variety of international customers. Weapons systems and munitions revenue was up driven by increased production of propellant and missile subcomponents. The Combat Systems segment’s operating margin increased 30 basis points in the first quarter of 2021 on a favorable product mix and continued cost reduction efforts.

*Command, control, communications, computers, intelligence, surveillance and reconnaissance
IT services revenue increased in the first quarter of 2021 due to the ramp up of several new programs. Revenue growth in C4ISR solutions was offset by the sale of a satellite communications business in the second quarter of 2020. Year-over-year organic growth for the segment was 5.3%, excluding the impact of the sale. The Technologies segment’s operating margin remained steady in the first quarter of 2021 as favorable contract mix offset the COVID-related impacts in our IT services business, particularly customer reimbursement of idle workforce cost at zero fee.
CORPORATE
Corporate operating results consisted primarily of equity-based compensation expense and totaled $32 in the first quarter of 2021 compared with $11 in the first quarter of 2020.

Total increase$175 
IT services revenue increased in the first quarter of 2021 due to the ramp up of several new programs. In the first quarter of 2021, the primary driver of the increase in service operating costs was the change in volume of IT services.
G&A EXPENSES
As a percentage of revenue, G&A expenses were 6% in the first three months of 2021 and 2020.
INTEREST, NET
Net interest expense was $123 in the first three months of 2021 compared with $107 in the prior-year period. The increase was due to incremental debt issued last year in conjunction with refinancing maturing notes. 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 $30 in the first three months of 2021 compared with $21 in the first three months of 2020. Other represents primarily the non-service components of pension and other post-retirement benefits, which were income in both periods.
PROVISION FOR INCOME TAX, NET
Our effective tax rate was 16.2% in the first three months of 2021 compared with 16.7% in the prior-year period.

BACKLOG AND ESTIMATED POTENTIAL CONTRACT VALUE
Our total backlog, including funded and unfunded portions, was $89.6 billion at the end of the first quarter of 2021 compared with $89.5 billion on December 31, 2020. Our total backlog is equal to our remaining performance obligations under contracts with customers as discussed in Note B 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 $131.4 billion on April 4, 2021.

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 first quarter of 2021 with backlog of $11.9 billion, up approximately 3% from $11.6 billion on December 31, 2020.
Orders in the first quarter of 2021 reflected strong demand across our aircraft portfolio. The segment’s book-to-bill ratio (orders divided by revenue) was 1.3-to-1 in the first quarter of 2021.
Beyond total backlog, estimated potential contract value represents primarily options and other agreements with existing customers to purchase new aircraft and long-term aircraft services agreements. On April 4, 2021, estimated potential contract value in the Aerospace segment was $2.3 billion.

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 total 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 of total backlog includes the amounts 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 unfunded work on indefinite delivery, indefinite quantity (IDIQ) contracts. Contract options 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
32


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.
Total backlog in our defense segments was $77.7 billion on April 4, 2021. The Technologies segment started 2021 with strong order activity, achieving a book-to-bill ratio of 1.1-to-1. Estimated potential contract value in our defense segments was $39.5 billion on April 4, 2021. We received the following significant contract awards during the first quarter of 2021:
Marine Systems:
$1.9 billion from the U.S. Navy for the construction of a tenth submarine in Block V of the Virginia-class submarine program.
$75 from the Navy for Advanced Nuclear Plant Studies (ANPS) in support of the Columbia-class submarine program.
$30 from the Navy for maintenance and modernization work on the USS Princeton, a Ticonderoga-class guided-missile cruiser.

A contract to provide software development and IT support services to the U.S. Patent and Trademark Office. The contract has a maximum potential value of $95.
$70 from the Army for the production of Prophet enhanced ground-based signals intelligence and electronic warfare systems.

FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES
We ended the first quarter of 2021 with a cash and equivalents balance of $1.8 billion compared with $2.8 billion at the end of 2020.
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 three months of 2021 and 2020, as classified on the unaudited Consolidated Statement of Cash Flows in Part I, Item 1.

OPERATING ACTIVITIES
Cash provided by operating activities was $3 in the first three months of 2021 compared with a use of cash of $666 in the same period in 2020. 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). Throughout 2020 we experienced growth in OWC in our Aerospace segment due to our position in the development and production cycles of our Gulfstream aircraft models. Although this Aerospace OWC growth began reversing in the fourth quarter of 2020 and continued in the first three months of 2021, the timing of billings and payments in our defense segments resulted in net OWC growth for the quarter.

INVESTING ACTIVITIES
Cash used by investing activities was $131 in the first three months of 2021 compared with $177 in the same period in 2020. 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. Capital expenditures were $134 in the first three months of 2021 compared with $185 in the same period in 2020.

34


FINANCING ACTIVITIES
Cash used by financing activities was $873 in the first three months of 2021 compared with cash provided of $5.3 billion in the same period in 2020. Net cash from financing activities includes proceeds received from debt and commercial paper issuances and employee stock option exercises. Our financing activities also include repurchases of common stock, payment of dividends and debt repayments.
Our board of directors from time to time authorizes management to repurchase outstanding shares of our common stock on the open market. We paid $759 and $449 in the first three months of 2021 and 2020, respectively, to repurchase our outstanding shares. On April 4, 2021, 7.7 million shares remained authorized by our board of directors for repurchase, representing 2.7% of our total shares outstanding.
On March 3, 2021, our board of directors declared an increased quarterly dividend of $1.19 per share, the 24th consecutive annual increase. Previously, the board had increased the quarterly dividend to $1.10 per share in March 2020. Cash dividends paid were $315 in the first three months of 2021 compared with $295 in the same period in 2020.
In March 2020, we issued $4 billion of fixed-rate notes. The proceeds were used to repay $2.5 billion of fixed- and floating-rate notes that matured in May 2020 and for general corporate purposes, including the repayment of a portion of the borrowings under our commercial paper program. Fixed- and floating-rate notes totaling $2.5 billion mature in May 2021, and an additional $500 of fixed-rate notes mature in July 2021. We plan to refinance a portion of these notes and repay the remainder 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, see Note I to the unaudited Consolidated Financial Statements in Part 1, Item 1.
In the first three months of 2020, we received net proceeds of $2.3 billion from the issuance of commercial paper. On April 4, 2021, we had no commercial paper outstanding, but we maintain the ability to access the commercial paper market in the future. Separately, we have $5 billion in committed bank credit facilities for general corporate purposes and working capital needs and to support our commercial paper issuances. We also have an effective shelf registration on file with the Securities and Exchange Commission (SEC) that allows us to access the debt markets.

NON-GAAP FINANCIAL MEASURES
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 and net debt to measure our performance in these areas. While we believe these metrics provide useful information, they are not defined operating measures under U.S. generally accepted accounting principles (GAAP), and there are limitations associated with their use. Our calculation of these metrics 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 these metrics should not be considered in isolation from, or as a substitute for, other GAAP measures.
35


Free Cash Flow. 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:

Cash flows as a percentage of net earnings:

Free cash flow from operations
(19)%(121)%
Net Debt. We define net debt as short- and long-term debt (total debt) less cash and equivalents. We believe net debt is a useful measure for investors because it reflects the borrowings that support our operations and capital deployment strategy. We use net debt as an important indicator of liquidity and financial position. The following table reconciles net debt with total debt:

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 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
36


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.
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 $63 ($0.17) and $90 ($0.25) for the three-month periods ended April 4, 2021, and March 29, 2020, respectively. No adjustment on any one contract was material to the unaudited Consolidated Financial Statements for the three-month periods ended April 4, 2021, or March 29, 2020.
Other critical accounting policies include long-lived assets and goodwill, commitments and contingencies, and retirement plans. For a full discussion of our critical accounting policies, see our Annual Report on Form 10-K for the year ended December 31, 2020.

GUARANTOR FINANCIAL INFORMATION
The fixed- and floating-rate notes described in Note I to the unaudited Consolidated Financial Statements in Part I, Item 1, issued by General Dynamics Corporation (the parent), are fully and unconditionally guaranteed on an unsecured, joint and several basis by several of the parent’s 100%-owned subsidiaries (the guarantors). The guarantee of each guarantor ranks equally in right of payment with all other existing and future senior unsecured indebtedness of such guarantor. A listing of the guarantors is included in an exhibit to this Form 10-Q.
Because the parent is a holding company, its cash flow and ability to service its debt, including the fixed- and floating-rate notes, depends on the performance of its subsidiaries and the ability of those subsidiaries to distribute cash to the parent, whether by dividends, loans or otherwise. Holders of the fixed- and floating-rate notes have a direct claim only against the parent and the guarantors.
Under the relevant indenture, the guarantee of each guarantor is limited to the maximum amount that can be guaranteed without rendering the guarantee voidable under applicable laws relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. Each indenture also provides that, in the event (1) of a merger, consolidation or sale or disposition of all or substantially all of the assets of a guarantor (other than a transaction with the parent or any of its subsidiaries) or (2) there occurs a transfer, sale or other disposition of the voting stock of a guarantor so that the guarantor is no longer a subsidiary of the parent, then the guarantor or the entity acquiring the assets (in the event of the sale or other disposition of all or substantially all of the assets of a guarantor) will be released and relieved of any obligations under the guarantee.
The following summarized financial information presents the parent and guarantors (collectively, the combined obligor group) on a combined basis. The summarized financial information of the combined obligor group excludes net investment in and earnings of subsidiaries related to interests held by the combined obligor group in subsidiaries that are not guarantors of the notes.
