NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)
1.    BASIS OF PRESENTATION
Principles of Consolidation and Reporting
These unaudited condensed consolidated financial statements (the “financial statements”) include the accounts of Northrop Grumman Corporation and its subsidiaries and joint ventures or other investments for which we consolidate the financial results (herein referred to as “Northrop Grumman,” the “company,” “we,” “us,” or “our”). Intercompany accounts, transactions and profits are eliminated in consolidation. Investments in equity securities and joint ventures where the company has significant influence, but not control, are accounted for using the equity method.
Effective January 30, 2021 (the “Divestiture date”), we completed the previously announced sale of our IT and mission support services business (the “IT services divestiture”) for $3.4 billion in cash and recorded a pre-tax gain on sale of $2.0 billion. The IT and mission support services business was comprised of the majority of the Information Solutions and Services (IS&S) division of Defense Systems (excluding our Vinnell Arabia business); select cyber, intelligence and missions support programs, which were part of the Cyber and Intelligence Mission Solutions (CIMS) division of Mission Systems; and the Space Technical Services business unit of Space Systems. The assets and liabilities of the IT and mission support services business were classified as held for sale in the consolidated statement of financial position as of December 31, 2020. Operating results include sales and operating income for the IT and mission support services business prior to the Divestiture date. Sales for the IT and mission support services business were $162 million for the nine months ended September 30, 2021 and $602 million and $1.7 billion for the three and nine months ended September 30, 2020, respectively. Pre-tax profit was $20 million for the nine months ended September 30, 2021, and $69 million and $180 million for the three and nine months ended September 30, 2020, respectively.
These financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP” or “FAS”) and in accordance with the rules of the Securities and Exchange Commission (SEC) for interim reporting. The financial statements include adjustments of a normal recurring nature considered necessary by management for a fair presentation of the company’s unaudited condensed consolidated financial position, results of operations and cash flows.
The results reported in these financial statements are not necessarily indicative of results that may be expected for the entire year. These financial statements should be read in conjunction with the information contained in the company’s 2020 Annual Report on Form 10-K. During the first quarter of 2021, we changed the naming convention for our FAS/CAS pension accounts. The Net FAS (service)/CAS pension adjustment is now referred to as the FAS/CAS operating adjustment and the FAS (non-service) pension benefit is now referred to as the Non-operating FAS pension benefit. This change does not impact any current or previously reported amounts. During the second quarter of 2021, we changed the presentation of the retiree benefits components in the operating cash flow section of the Unaudited condensed consolidated statement of cash flows. Prior period amounts have been conformed to current period presentation and this change does not impact previously reported cash provided by operating activities.
The quarterly information is labeled using a calendar convention; that is, first quarter is consistently labeled as ending on March 31, second quarter as ending on June 30 and third quarter as ending on September 30. It is the company’s long-standing practice to establish actual interim closing dates using a “fiscal” calendar, in which we close our books on a Friday near these quarter-end dates in order to normalize the potentially disruptive effects of quarterly closings on business processes. This practice is only used at interim periods within a reporting year.
Accounting Estimates
Preparation of the financial statements requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingencies at the date of the financial statements, as well as the reported amounts of sales and expenses during the reporting period. Estimates have been prepared using the most current and best available information; however, actual results could differ materially from those estimates.
Revenue Recognition
The majority of our sales are derived from long-term contracts with the U.S. government for the development or production of goods, the provision of services, or a combination of both. We recognize revenue as control is transferred to the customer, either over time or at a point in time. For most of our contracts, control is effectively transferred during the period of performance, so we generally recognize revenue over time using the cost-to-cost method (cost incurred relative to total cost estimated at completion). The company believes this represents the most
-5-

NORTHROP GRUMMAN CORPORATION                        
appropriate measurement towards satisfaction of our performance obligations. Revenue for contracts in which the control of goods produced does not transfer until delivery to the customer is recognized at a point in time (i.e., typically upon delivery).
Contract Estimates
Use of the cost-to-cost method requires us to make reasonably dependable estimates regarding the revenue and cost associated with the design, manufacture and delivery of our products and services. The company estimates profit on these contracts as the difference between total estimated sales and total estimated cost at completion and recognizes that profit as costs are incurred. Significant judgment is used to estimate total sales and cost at completion.
Contract sales may include estimates of variable consideration, including cost or performance incentives (such as award and incentive fees), contract claims and requests for equitable adjustment (REAs). Variable consideration is included in total estimated sales to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. We estimate variable consideration as the most likely amount to which we expect to be entitled.
We recognize changes in estimated contract sales or costs and the resulting changes in contract profit on a cumulative basis. Cumulative estimate-at-completion (EAC) adjustments represent the cumulative effect of the changes on current and prior periods; sales and operating margins in future periods are recognized as if the revised estimates had been used since contract inception. If it is determined that a loss is expected to result on an individual performance obligation, the entire amount of the estimable future loss, including an allocation of general and administrative expense, is charged against income in the period the loss is identified.
The following table presents the effect of aggregate net EAC adjustments:

(1)Based on a 21 percent statutory tax rate.
EAC adjustments on a single performance obligation can have a material effect on the company’s financial statements. When such adjustments occur, we generally disclose the nature, underlying conditions and financial impact of the adjustments. During the third quarter of 2021, we recorded a $42 million unfavorable EAC adjustment on the F-35 program at Aeronautics Systems due to labor-related production inefficiencies largely driven by COVID-19-related impacts on the labor market and employee leave. No such adjustments were material to the financial statements during the three months ended September 30, 2020.
Backlog
Backlog represents the future sales we expect to recognize on firm orders received by the company and is equivalent to the company’s remaining performance obligations at the end of each period. It comprises both funded backlog (firm orders for which funding is authorized and appropriated) and unfunded backlog. Unexercised contract options and indefinite delivery indefinite quantity (IDIQ) contracts are not included in backlog until the time an option or IDIQ task order is exercised or awarded.
Company backlog as of September 30, 2021 was $74.8 billion. Of our September 30, 2021 backlog, we expect to recognize approximately 40 percent as revenue over the next 12 months and 60 percent as revenue over the next 24 months, with the remainder to be recognized thereafter.
Contract Assets and Liabilities
For each of the company’s contracts, the timing of revenue recognition, customer billings, and cash collections results in a net contract asset or liability at the end of each reporting period. Contract assets are equivalent to and reflected as Unbilled receivables in the unaudited condensed consolidated statements of financial position and are primarily related to long-term contracts where revenue recognized under the cost-to-cost method exceeds amounts billed to customers. Contract liabilities are equivalent to and reflected as Advance payments and billings in excess of costs incurred in the unaudited condensed consolidated statements of financial position. The amount of revenue recognized for the three and nine months ended September 30, 2021 that was included in the December 31, 2020

contract liability balances was $261 million and $1.8 billion, respectively. The amount of revenue recognized for the three and nine months ended September 30, 2020 that was included in the December 31, 2019 contract liability balance was $232 million and $1.5 billion, respectively.
Disaggregation of Revenue
See Note 9 for information regarding the company’s sales by customer type, contract type and geographic region for each of our segments. We believe those categories best depict how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors.
Property, Plant, and Equipment
In the fourth quarter of 2020, the company completed a sale of equipment to a customer on a restricted Aeronautics Systems program. During the nine months ended September 30, 2021, the company received cash payments of $84 million related to the equipment sale and included it in Proceeds from sale of equipment to a customer in the unaudited condensed consolidated statement of cash flows.
Non-cash investing activities include capital expenditures incurred but not yet paid of $105 million and $123 million as of September 30, 2021 and 2020, respectively.
Accumulated Other Comprehensive Loss
The components of accumulated other comprehensive loss are as follows:

Related Party Transactions
For all periods presented, the company had no material related party transactions.
Accounting Standards Updates
Accounting standards updates adopted and/or issued, but not effective until after September 30, 2021, are not expected to have a material effect on the company’s unaudited condensed consolidated financial position, annual results of operations and/or cash flows.
2.    EARNINGS PER SHARE, SHARE REPURCHASES AND DIVIDENDS ON COMMON STOCK
Basic Earnings Per Share
We calculate basic earnings per share by dividing net earnings by the weighted-average number of shares of common stock outstanding during each period.
Diluted Earnings Per Share
Diluted earnings per share include the dilutive effect of awards granted to employees under stock-based compensation plans. The dilutive effect of these securities totaled 0.6 million shares and 0.5 million shares for the three and nine months ended September 30, 2021, respectively. The dilutive effect of these securities totaled 0.5 million shares and 0.6 million shares for the three and nine months ended September 30, 2020, respectively.
Share Repurchases
On September 16, 2015, the company’s board of directors authorized a share repurchase program of up to $4.0 billion of the company’s common stock (the “2015 Repurchase Program”). On December 4, 2018, the company’s board of directors authorized a share repurchase program of up to an additional $3.0 billion in share repurchases of the company’s common stock (the “2018 Repurchase Program”). Repurchases under the 2015 Repurchase Program commenced in March 2016 and were completed in March 2020 at which time repurchases under the 2018 Repurchase Program commenced. As of September 30, 2021, repurchases under the 2018 Repurchase Program totaled $2.9 billion; $0.1 billion remained under this share repurchase authorization. By its terms, the 2018 Repurchase Program is set to expire when we have used all authorized funds for repurchases.
On January 25, 2021, the company’s board of directors authorized a new share repurchase program of up to an additional $3.0 billion in share repurchases of the company’s common stock (the “2021 Repurchase Program”). By its terms, repurchases under the 2021 Repurchase Program will commence upon completion of the 2018 Repurchase Program and will expire when we have used all authorized funds for repurchases.

During the first quarter of 2021, the company entered into an accelerated share repurchase (ASR) agreement with Goldman Sachs & Co. LLC (Goldman Sachs) to repurchase $2.0 billion of the company’s common stock as part of the 2018 Repurchase Program. Under the agreement, we made a payment of $2.0 billion to Goldman Sachs and received an initial delivery of 5.9 million shares valued at $1.7 billion that were immediately canceled by the company. The remaining balance of $300 million was settled on June 1, 2021 with a final delivery of 0.2 million shares from Goldman Sachs. The final average purchase price was $327.29 per share.
Share repurchases take place from time to time, subject to market conditions and management’s discretion, in the open market or in privately negotiated transactions. The company retires its common stock upon repurchase and, in the periods presented, has not made any purchases of common stock other than in connection with these publicly announced repurchase programs.

Effective income tax rate16.6 %15.5 %23.2 %16.5 %
Current Quarter
The third quarter 2021 effective tax rate (ETR) increased to 16.6 percent from 15.5 percent in the prior year period primarily due to lower benefits from foreign-derived intangible income (FDII). The company’s third quarter 2021 ETR includes benefits of $43 million for research credits and $12 million for FDII. The company’s third quarter 2020 ETR included benefits of $45 million for research credits and $30 million for FDII, which reflects additional benefits after final regulations issued in July 2020 clarified Foreign Military Sales qualify for the deduction.
Year to Date
The year to date 2021 ETR increased to 23.2 percent from 16.5 percent in the prior period primarily due to federal income taxes resulting from the IT services divestiture, including $250 million of income tax expense related to $1.2 billion of nondeductible goodwill in the divested business. The company’s year to date 2021 ETR also includes additional tax expense related to a change made in tax revenue recognition on certain long-term contracts, which increased taxable income in years prior to the 2017 Tax Cuts and Jobs Act at a rate above the current statutory rate as well as benefits of $142 million for research credits and $32 million for FDII. The company’s year to date 2020 ETR included benefits of $135 million for research credits and $46 million for FDII.
Taxes receivable, which are included in Prepaid expenses and other current assets in the unaudited condensed consolidated statements of financial position, were $123 million as of September 30, 2021 and $792 million as of December 31, 2020.
The company has recorded unrecognized tax benefits related to our methods of accounting associated with the timing of revenue recognition and related costs and the 2017 Tax Cuts and Jobs Act, which includes related final revenue recognition regulations issued in December 2020 under IRC Section 451(b) and procedural guidance issued

in August 2021. It is reasonably possible that within the next 12 months our unrecognized tax benefits related to these matters may increase by approximately $100 million.
We file income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. The Northrop Grumman 2017-2018 federal tax returns are currently under Internal Revenue Service (IRS) examination. During the third quarter of 2021, the company requested an appeal with the IRS for the Northrop Grumman 2014-2016 federal income tax returns and refund claims related to its 2007-2016 federal tax returns. In addition, legacy Orbital ATK federal tax returns for the year ended March 31, 2015, the nine-month transition period ended December 31, 2015 and calendar years 2016-2017 are currently under appeal with the IRS.
4.    FAIR VALUE OF FINANCIAL INSTRUMENTS
The company holds a portfolio of marketable securities to partially fund non-qualified employee benefit plans. A portion of these securities are held in common/collective trust funds and are measured at fair value using net asset value (NAV) per share as a practical expedient; and therefore are not required to be categorized in the fair value hierarchy table below. Marketable securities are included in Other non-current assets in the unaudited condensed consolidated statements of financial position.
The company’s derivative portfolio consists primarily of foreign currency forward contracts. Where model-derived valuations are appropriate, the company utilizes the income approach to determine the fair value and uses the applicable London Interbank Offered Rate (LIBOR) swap rates.
The following table presents the financial assets and liabilities the company records at fair value on a recurring basis identified by the level of inputs used to determine fair value:

Marketable securities valued using NAV16 18 
Total marketable securities390  406 377 396 
Derivatives 3 3 — — — 
The notional value of the company’s foreign currency forward contracts at September 30, 2021 and December 31, 2020 was $132 million and $133 million, respectively. At September 30, 2021 and December 31, 2020, no portion of the notional value was designated as a cash flow hedge.
The derivative fair values and related unrealized gains/losses at September 30, 2021 and December 31, 2020 were not material. There were no transfers of financial instruments into or out of Level 3 of the fair value hierarchy during the nine months ended September 30, 2021.
The carrying value of cash and cash equivalents and commercial paper approximates fair value.
Long-term Debt
The estimated fair value of long-term debt was $15.2 billion and $18.2 billion as of September 30, 2021 and December 31, 2020, respectively. We calculated the fair value of long-term debt using Level 2 inputs, based on interest rates available for debt with terms and maturities similar to the company’s existing debt arrangements. The current portion of long-term debt is recorded in Other current liabilities in the unaudited condensed consolidated statements of financial position.
On September 2, 2021, the company completed an exchange offer to eligible holders of the outstanding notes of our direct wholly owned subsidiary, Northrop Grumman Systems Corporation (“NGSC”) maturing through 2036. An aggregate principal amount of $422 million of the NGSC notes was exchanged for $422 million of Northrop Grumman Corporation notes with the same interest rates and maturity dates as the NGSC notes exchanged. Because the debt instruments are not substantially different, the exchange was treated as a debt modification for accounting purposes with no gain or loss recognized.
Repayments of Senior Notes
In March 2021, the company repaid $700 million of 3.50 percent unsecured notes upon maturity.
In March 2021, the company redeemed $1.5 billion of 2.55 percent unsecured notes due October 2022. The company recorded a pre-tax charge of $54 million principally related to the premium paid on the redemption, which

5.    INVESTIGATIONS, CLAIMS AND LITIGATION
On May 4, 2012, the company commenced an action, Northrop Grumman Systems Corp. v. United States, in the U.S. Court of Federal Claims. This lawsuit relates to an approximately $875 million firm fixed-price contract awarded to the company in 2007 by the U.S. Postal Service (USPS) for the construction and delivery of flats sequencing systems (FSS) as part of the postal automation program. The FSS were delivered. The company’s lawsuit seeks approximately $63 million for unpaid portions of the contract price, and approximately $115 million based on the company’s assertions that, through various acts and omissions over the life of the contract, the USPS adversely affected the cost and schedule of performance and materially altered the company’s obligations under the contract. The United States responded to the company’s complaint with an answer, denying most of the company’s claims, and counterclaims seeking approximately $410 million, less certain amounts outstanding under the contract. In the course of the litigation, the United States subsequently amended its counterclaim, reducing it to seek approximately $193 million. The principal counterclaim alleges that the company delayed its performance and caused damages to the USPS because USPS did not realize certain costs savings as early as it had expected. On February 3, 2020, after extensive discovery and motions practice, the parties commenced what was expected to be a seven-week trial. The first four weeks of trial concluded, but the court postponed the remaining estimated three weeks as a result of COVID-19-related concerns. After additional COVID-19-related interruptions, trial concluded on March 5, 2021. On October 12, 2021, the parties completed post-trial briefing, absent any further requests or unexpected developments. Although the ultimate outcome of this matter, including any possible loss, cannot be predicted or reasonably estimated at this time, the company intends to continue vigorously to pursue and defend the matter.
We are engaged in remediation activities relating to environmental conditions allegedly resulting from historic operations at the former United States Navy and Grumman facilities in Bethpage, New York. For over 20 years, we have worked closely with the United States Navy, the United States Environmental Protection Agency, the New York State Department of Environmental Conservation (NYSDEC), the New York State Department of Health and other federal, state and local governmental authorities, to address legacy environmental conditions in Bethpage. In December 2019, the State of New York issued an Amended Record of Decision seeking to impose additional remedial requirements beyond measures the company previously had been taking; the State also communicated that it was assessing potential natural resource damages. In December 2020, the parties reached a tentative agreement regarding the steps the company will take to implement the State’s Amended Record of Decision and to resolve certain potential other claims, including for natural resource damages. On September 22, 2021, the State of New York issued for public comment a new consent decree reflecting the agreement. We understand that the State will next seek court approval of the consent decree. We have incurred, and expect to continue to incur, as included in Note 6, substantial remediation costs related to the legacy Bethpage environmental conditions. Applicable remediation standards and other requirements to which we are subject may continue to change, our costs may increase materially and those costs may not be fully recoverable. In addition, we are a party to various, and expect to become a party to additional, legal proceedings and disputes related to remediation, environmental impacts, costs, and the allowability of costs we incur, including with federal and state entities (including the Navy, Defense Contract Management Agency, the State, local municipalities and water districts) and insurance carriers, as well as class action and individual plaintiffs alleging personal injury and property damage and seeking both monetary and non-monetary relief. These Bethpage matters could result in additional costs, fines, penalties, sanctions, compensatory or other damages, determinations on allocation, allowability and coverage, and non-monetary relief. We are in discussions with the Department of Defense and the Bethpage Water District to explore whether claims involving these parties can be resolved at this stage. We cannot at this time predict or reasonably estimate the potential cumulative outcomes or ranges of possible liability of these aggregate Bethpage matters.
The company is a party to various other investigations, lawsuits, arbitration, claims, enforcement actions and other legal proceedings, including government investigations and claims, that arise in the ordinary course of our business. The nature of legal proceedings is such that we cannot assure the outcome of any particular matter. However, based on information available to the company to date, the company does not believe that the outcome of any of these other matters pending against the company is likely to have a material adverse effect on the company’s unaudited condensed consolidated financial position as of September 30, 2021, or its annual results of operations and/or cash flows.

6.    COMMITMENTS AND CONTINGENCIES
U.S. Government Cost Claims and Contingencies
From time to time, the company is advised of claims by the U.S. government concerning certain potential disallowed costs, plus, at times, penalties and interest. When such findings are presented, the company and U.S. government representatives engage in discussions to enable the company to evaluate the merits of these claims, as well as to assess the amounts being claimed. Where appropriate, provisions are made to reflect the company’s estimated exposure for such potential disallowed costs. Such provisions are reviewed periodically using the most recent information available. The company believes it has adequately reserved for disputed amounts that are probable and reasonably estimable, and that the outcome of any such matters would not have a material adverse effect on its unaudited condensed consolidated financial position as of September 30, 2021, or its annual results of operations and/or cash flows.
The U.S. government has raised questions about an interest rate assumption used by the company to determine our CAS pension expense. On June 1, 2020, the government provided written notice that the assumptions the company used during the period 2013-2019 were potentially noncompliant with CAS. We submitted a formal response on July 31, 2020, which we believe demonstrates the appropriateness of the assumptions used. On November 24, 2020, the government replied to the company’s response, disagreeing with our position and requesting additional input, which we provided on February 22, 2021. We are engaging further with the government. The sensitivity to changes in interest rate assumptions makes it reasonably possible the outcome of this matter could have a material adverse effect on our financial position, results of operations and/or cash flows, although we are not currently able to estimate a range of any potential loss.
Environmental Matters
The table below summarizes the amount accrued for environmental remediation costs, management’s estimate of the amount of reasonably possible future costs in excess of accrued costs and the deferred costs expected to be recoverable through overhead charges on U.S. government contracts as of September 30, 2021 and December 31, 2020:
$ in millions
Accrued Costs(1)(2)
Reasonably Possible Future Costs in Excess of Accrued Costs(2)
Deferred Costs(3)
September 30, 2021$600 $366 $514 
December 31, 2020614 346 529 
(1) As of September 30, 2021, $235 million is recorded in Other current liabilities and $365 million is recorded in Other non-current liabilities.
(2) Estimated remediation costs are not discounted to present value. The reasonably possible future costs in excess of accrued costs do not take into consideration amounts expected to be recoverable through overhead charges on U.S. government contracts.
(3) As of September 30, 2021, $205 million is deferred in Prepaid expenses and other current assets and $309 million is deferred in Other non-current assets. These amounts are evaluated for recoverability on a routine basis.
Although management cannot predict whether new information gained as our environmental remediation projects progress, or as changes in facts and circumstances occur, will materially affect the estimated liability accrued, except with respect to Bethpage, we do not anticipate that future remediation expenditures associated with our currently identified projects will have a material adverse effect on the company’s unaudited condensed consolidated financial position as of September 30, 2021, or its annual results of operations and/or cash flows.
With respect to Bethpage, as discussed in Note 5, in December 2019, the State of New York issued an Amended Record of Decision, seeking to impose additional remedial requirements beyond those the company previously had been taking; the State also communicated that it was assessing potential natural resource damages. In December 2020, the parties reached a tentative agreement regarding the steps the company will take to implement the State’s Amended Record of Decision and to resolve certain potential other claims, including for natural resource damages. On September 22, 2021, the State of New York issued for public comment a new consent decree reflecting the agreement. We understand that the State will next seek court approval of the consent decree. As discussed in Note 5, the applicable remediation standards and other requirements to which we are subject may continue to change, our costs may increase materially, and those costs may not be fully recoverable.

FAS/CAS Operating Adjustment
For financial statement purposes, we account for our employee pension plans in accordance with FAS. However, the cost of these plans is charged to our contracts in accordance with the Federal Acquisition Regulation (FAR) and the related U.S. Government Cost Accounting Standards (CAS). The FAS/CAS operating adjustment, previously referred to as the net FAS (service)/CAS pension adjustment, reflects the difference between CAS pension expense included as cost in segment operating income and the service cost component of FAS expense included in total operating income.
Unallocated Corporate (Expense) Income
Unallocated corporate (expense) income includes the portion of corporate costs not considered allowable or allocable under applicable CAS or FAR, and therefore not allocated to the segments, such as changes in deferred state income taxes and a portion of management and administration, legal, environmental, compensation, retiree benefits, advertising and other corporate unallowable costs. Unallocated corporate (expense) income also includes costs not considered part of management’s evaluation of segment operating performance, such as amortization of purchased intangible assets and the additional depreciation expense related to the step-up in fair value of property, plant and equipment acquired through business combinations, as well as certain compensation and other costs.
During the first quarter of 2021, the $2.0 billion pre-tax gain on the sale of our IT services business and $192 million of unallowable state taxes and transaction costs associated with the divestiture were recorded in Unallocated corporate (expense) income.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Shareholders of
Northrop Grumman Corporation
Falls Church, Virginia
Results of Review of Interim Financial Information
We have reviewed the accompanying condensed consolidated statement of financial position of Northrop Grumman Corporation and subsidiaries (the “Company”) as of September 30, 2021, and the related condensed consolidated statements of earnings and comprehensive income and changes in shareholders’ equity for the three-month and nine-month periods ended September 30, 2021 and 2020, and of cash flows for the nine-month periods ended September 30, 2021 and 2020, and the related notes (collectively referred to as the “interim financial information”). Based on our review, we are not aware of any material modifications that should be made to the accompanying interim financial information for it to be in conformity with accounting principles generally accepted in the United States of America.
We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated statement of financial position of Northrop Grumman Corporation and subsidiaries as of December 31, 2020, and the related consolidated statements of earnings and comprehensive income, changes in shareholders’ equity, and cash flows for the year then ended (not presented herein); and in our report dated January 27, 2021, we expressed an unqualified opinion on those consolidated financial statements, which included an explanatory paragraph regarding the Company’s change in its method of accounting for leases in 2019 due to the adoption of ASC 842, Leases. In our opinion, the information set forth in the accompanying condensed consolidated statement of financial position as of December 31, 2020, is fairly stated, in all material respects, in relation to the audited consolidated statement of financial position from which it has been derived.
Basis for Review Results
This interim financial information is the responsibility of the Company’s management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our reviews in accordance with standards of the PCAOB. A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Item 2.    Management’s Discussion and Analysis of Financial Condition and Results of Operations
OVERVIEW
Northrop Grumman Corporation (herein referred to as “Northrop Grumman,” the “company,” “we,” “us,” or “our”) is a leading global aerospace and defense company. We use our broad portfolio of capabilities and technologies to create and deliver innovative platforms, systems and solutions in space; manned and autonomous airborne systems, including strike; strategic deterrence systems; hypersonics; missile defense; weapons systems; cyber; command, control, communications and computers, intelligence, surveillance and reconnaissance (C4ISR); and logistics and modernization. We participate in many high-priority defense and government programs in the United States (U.S.) and abroad. We conduct most of our business with the U.S. government, principally the Department of Defense (DoD) and intelligence community. We also conduct business with other governments, including foreign governments, and commercial customers.
The following discussion should be read along with the financial statements included in this Form 10-Q, as well as our 2020 Annual Report on Form 10-K, which provides additional information on our business and the environment in which we operate and our operating results.
Divestiture of IT and Mission Support Services Business
Effective January 30, 2021 (the “Divestiture date”), we completed the previously announced sale of our IT and mission support services business (the “IT services divestiture”) for $3.4 billion in cash and recorded a pre-tax gain on sale of $2.0 billion. The IT and mission support services business was comprised of the majority of the Information Solutions and Services (IS&S) division of Defense Systems (excluding our Vinnell Arabia business); select cyber, intelligence and missions support programs, which were part of the Cyber and Intelligence Mission Solutions (CIMS) division of Mission Systems; and the Space Technical Services business unit of Space Systems. Operating results include sales and operating income for the IT and mission support services business prior to the Divestiture date.
COVID-19
Coronavirus disease 2019, which was first reported in late 2019, and subsequent variants (collectively “COVID-19” or the “pandemic”), have dramatically impacted the global health and economic environment, including millions of confirmed cases and deaths, business slowdowns or shutdowns, labor shortfalls, supply chain challenges, regulatory challenges, and market volatility. We discuss in some detail in our Annual Report on Form 10-K, and subsequent SEC filings, the pandemic, its impacts and risks, and actions taken up to the time of filing. In this Form 10-Q, we provide a further update. We continue closely to monitor and address the developments, including the impact on our company, our employees, our customers, our suppliers and our communities. The company continues to consider and be guided by health data and evolving guidance from the Centers for Disease Control and Prevention (CDC), in particular, as well as other health organizations globally, federal, state and local governmental authorities, and our customers, among others. During the course of this year, COVID-19 case rates and the health impacts of the pandemic have fluctuated dramatically in different communities in the U.S. and globally. We have continued to see a prolonged impact on the economy, our industry, and our company, with increased challenges for customers and suppliers, labor shortages (including greater leave-taking), supply chain challenges, and increasing inflation, among other impacts. We expect these and other impacts to continue and they could worsen, depending on the future course of the pandemic and actions taken in connection with it.
In the U.S., the Food and Drug Administration issued emergency use authorization for COVID-19 vaccines and the government began extensive efforts to administer them. The company also has taken various steps to facilitate vaccination access for our employees, in accordance with federal guidance. We have provided paid leave and flexibility for employees to get vaccinated, and strongly encouraged our workforce to take care of themselves and their colleagues. In September 2021, the White House issued an executive order and guidance from the Safer Federal Workforce Task Force broadly requiring many U.S.-based federal contractors to be fully vaccinated by December 8, 2021 (with exceptions including where an employee is legally entitled to an accommodation). We are taking steps to comply with the executive order, guidance, and related contract terms, broadly requiring vaccination among our U.S.-based employees. We are continuing to evaluate these evolving requirements, especially as our customers determine when and how to implement new contractual obligations, but we cannot at this stage predict the various impacts they may have on our workforce, our suppliers, or our company. The Occupational Safety and Health Administration has said it is developing an emergency temporary standard for employers with 100 or more employees to ensure their workers are fully vaccinated or undergo weekly testing. State and local governments are also taking actions related to the pandemic, imposing additional and varying requirements on industry. These evolving government requirements, including regarding a vaccine mandate, along with the broader impacts of the continuing pandemic, could significantly impact our workforce and performance, as well as those of our suppliers,

and result in costs that we may not be able to recover fully. The company continues to take robust actions globally to protect the health, safety and well-being of our employees, and to serve our customers with continued performance. We also continue to take steps to support our suppliers, with a particular focus on critical small and midsized business partners, including passing through increased progress payments from the DoD to our suppliers and accelerating payments to certain suppliers.
The company’s third quarter 2021 revenue and operating income were affected by the impact of the COVID-19 pandemic on the company and the broader economic environment, including through a tightened labor market, elevated levels of employee leave, evolving government requirements, and supply chain challenges. These factors could worsen and affect further our ability (and that of our suppliers) to maintain a qualified workforce and to perform fully for our customers (including with respect to cost and schedule), with reduced sales and additional liabilities, losses and costs, that we may not be able to recover fully. Our employees, customers and suppliers, the company, our economy and our global community continue to face both continuing and new or evolving challenges, including related to the vaccine mandate, and we cannot predict how this dynamic situation will evolve or the impact it will have on the company, or our financial position, results of operations and/or cash flows. For further information on the pandemic and the potential impact to the company of COVID-19, see “Liquidity and Capital Resources” below and “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2020 Annual Report on Form 10-K and Quarterly Reports on Form 10-Q.
U.S. Political and Economic Environment
On May 28, 2021, the Administration released its budget request for fiscal year (FY) 2022. The budget proposes $753 billion for national defense programs and $770 billion in non-defense discretionary funding, and continues to be the subject of debate in Congress. The Administration’s budget request includes funding for the American Jobs Plan, a $2.3 trillion infrastructure and economic recovery plan, and the American Families Plan, a $1.8 trillion education and economic support plan. If some or all of these plans are enacted, they may have broader implications for the defense industry, our customers’ budgets and priorities, and the overall economic environment, including the national debt. It is difficult to predict the specific course of future defense budgets. However, the threat to national security remains very substantial and we believe that our capabilities, particularly in space, missiles, missile defense, hypersonics, counter-hypersonics, survivable aircraft and mission systems should help our customers to meet the threats and, as a result, continue to allow for long-term profitable growth in our business.
FY 2022 appropriations have not been enacted, to date, and, on September 30, 2021, a continuing resolution was enacted, providing funding generally at FY 2021 levels through December 3, 2021. The Congress’ FY 2022 deliberations have demonstrated broad support for national security, and in key pieces of legislation, have proposed increased funding for national defense above the Administration’s budget request. It remains uncertain whether and, if so, when the government will approve FY 2022 appropriations, with which programs funded at what levels, and for how long the government will operate under a continuing resolution, with potential impacts on our programs and new starts, in particular.
On October 14, 2021, the statutory debt limit was increased by $480 billion, which reportedly allows the Treasury Department to finance the government through approximately early December 2021. If the debt limit is not lifted, or further increased, and the debt ceiling is breached, there may be significant consequences for our customers and programs, and we may be required to continue to perform for some period of time on certain of our U.S. Government contracts even if the U.S. Government is unable to make timely payments.
The political environment, federal budget and debt ceiling are expected to continue to be the subject of considerable debate, which could have material impacts on defense spending broadly and the company’s programs in particular.
For further information on the risks we face from the current political and economic environment, see “Risk Factors” in our 2020 Annual Report on Form 10-K.

CONSOLIDATED OPERATING RESULTS
For purposes of the operating results discussion below, we assess our performance using certain financial measures that are not calculated in accordance with GAAP. Organic sales is defined as total sales excluding sales attributable to the company's IT services divestiture. This measure may be useful to investors and other users of our financial statements as a supplemental measure in evaluating the company’s underlying sales growth as well as in providing an understanding of our ongoing business and future sales trends by presenting the company’s sales before the impact of divestiture activity.
Transaction-adjusted net earnings and transaction-adjusted earnings per share (transaction-adjusted EPS) exclude impacts related to the IT services divestiture, including the gain on sale of the business, associated federal and state income tax expenses, transaction costs, and the make-whole premium for early debt redemption. They also exclude the impact of mark-to-market pension and OPB (“MTM”) expense and related tax impacts, which are generally only recognized during the fourth quarter. These non-GAAP measures may be useful to investors and other users of our financial statements as supplemental measures in evaluating the company’s underlying financial performance by presenting the company’s operating results before the non-operational impact of divestiture activity and pension and OPB actuarial gains and losses. These measures are also consistent with how management views the underlying performance of the business as the impact of the IT services divestiture and MTM accounting are not considered in management’s assessment of the company’s operating performance or in its determination of incentive compensation awards.
We reconcile these non-GAAP financial measures to their most directly comparable GAAP financial measures below. These non-GAAP measures may not be defined and calculated by other companies in the same manner and should not be considered in isolation or as an alternative to operating results presented in accordance with GAAP.

Current Quarter
Third quarter 2021 sales decreased $363 million, or 4 percent, due to lower sales at Defense Systems and Missions Systems, principally due to the impact of the IT services divestiture, and lower sales at Aeronautics Systems, partially offset by 22 percent sales growth at Space Systems. Third quarter 2021 sales were affected by the impact of COVID-19 on the broader economic environment, including a tight labor market, elevated levels of employee leave, and supply chain challenges. Third quarter 2021 organic sales increased $239 million, or 3 percent.
Year to Date
Year to date 2021 sales increased $441 million, or 2 percent, primarily due to higher sales at Space Systems and Mission Systems, partially offset by lower sales at Defense Systems, principally due to the impact of the IT services divestiture. Year to date 2021 organic sales increased $2.0 billion, or 8 percent. As a result of the company using a fiscal calendar convention for interim reporting periods (as described in Note 1 to the financial statements), year to date 2021 sales at each sector benefited approximately 2 percent from three additional working days when compared to the prior year period.
See “Segment Operating Results” below for further information by segment and “Product and Service Analysis” for product and service detail. See Note 9 to the financial statements for information regarding the company’s sales by customer type, contract type and geographic region for each of our segments.

Operating Income and Margin Rate
Current Quarter
Third quarter 2021 operating income increased $58 million, or 6 percent, primarily due to lower unallocated corporate expense, partially offset by a lower FAS/CAS operating adjustment. Third quarter 2021 operating margin rate increased to 12.0 percent reflecting a higher segment operating margin rate in addition to the items above.
Third quarter 2021 general and administrative (G&A) costs as a percentage of sales increased to 10.2 percent from 9.4 percent in the prior year period primarily due to an increase in investments for future business opportunities as well as the timing of indirect cost recognition during the quarter.
Year to Date
Year to date 2021 operating income increased $2.0 billion, or 69 percent, primarily due to the IT services divestiture, including the $2.0 billion pre-tax gain on sale and $192 million of unallocated corporate expense for unallowable state taxes and transaction costs. Operating income also increased due to lower non-divestiture-related unallocated corporate expenses and higher segment operating income, partially offset by a lower FAS/CAS operating adjustment. Year to date 2021 operating margin rate increased to 18.2 percent reflecting the items above.
Year to date 2021 G&A costs as a percentage of sales increased to 10.3 percent from 9.3 percent in the prior year period primarily due to an increase in investments for future business opportunities as well as the timing of indirect cost recognition during the year.
See “Segment Operating Results” below for further information by segment. For information regarding product and service operating costs and expenses, see “Product and Service Analysis” below.
Federal and Foreign Income Taxes
Current Quarter
The third quarter 2021 effective tax rate (ETR) increased to 16.6 percent from 15.5 percent in the prior year period primarily due to lower benefits from foreign-derived intangible income. See Note 3 to the financial statements for additional information.
Year to Date
The year to date 2021 ETR increased to 23.2 percent from 16.5 percent in the prior period primarily due to federal income taxes resulting from the IT services divestiture. See Note 3 to the financial statements for additional information.

SEGMENT OPERATING RESULTS
Basis of Presentation
The company is aligned in four operating sectors, which also comprise our reportable segments: Aeronautics Systems, Defense Systems, Mission Systems and Space Systems. We present our sectors in the following business areas, which are reported in a manner reflecting core capabilities:
Aeronautics SystemsDefense SystemsMission SystemsSpace Systems
Autonomous SystemsBattle Management & Missile SystemsAirborne Multifunction SensorsLaunch & Strategic Missiles
Manned AircraftMission ReadinessMaritime/Land Systems & SensorsSpace
Navigation, Targeting & Survivability
Networked Information Solutions
Effective during the first quarter of 2021 within Mission Systems, the businesses of the former Cyber & Intelligence Mission Solutions business area that remained with Northrop Grumman after the IT services divestiture were merged with the Communications business unit and F-35 Communications, Navigation and Identification programs within the former Airborne, Sensors & Networks business area to form the Networked Information Solutions business area. The Airborne Sensors & Networks business area was then renamed the Airborne Multifunction Sensors business area to better reflect its new portfolio. This change had no impact on the segment operating results of Mission Systems as a whole.
This section discusses segment sales, operating income and operating margin rates. In evaluating segment operating performance, we look primarily at changes in sales and operating income. Where applicable, significant fluctuations in operating performance attributable to individual contracts or programs, or changes in a specific cost element across multiple contracts, are described in our analysis. Based on this approach and the nature of our operations, the discussion of results of operations below first focuses on our four segments before distinguishing between products and services. Changes in sales are generally described in terms of volume, while changes in margin rates are generally described in terms of performance and/or contract mix. For purposes of this discussion, volume generally refers to increases or decreases in sales or cost from production/service activity levels and performance generally refers to non-volume related changes in profitability. Contract mix generally refers to changes in the ratio of contract type and/or lifecycle (e.g., cost-type, fixed-price, development, production, and/or sustainment).

Segment Operating Income and Margin Rate
Segment operating income, as reconciled in the table below, and segment operating margin rate (segment operating income divided by sales) are non-GAAP (accounting principles generally accepted in the United States of America) measures that reflect total earnings from our four segments, including allocated pension expense we have recognized under the Federal Acquisition Regulation (FAR) and the related U.S. Government Cost Accounting Standards (CAS), and excluding FAS pension service expense and unallocated corporate items (certain corporate-level expenses, which are not considered allowable or allocable under requirements in the applicable CAS or FAR, and costs not considered part of management’s evaluation of segment operating performance). These non-GAAP measures may be useful to investors and other users of our financial statements as supplemental measures in evaluating the financial performance and operational trends of our sectors. These measures may not be defined and calculated by other companies in the same manner and should not be considered in isolation or as alternatives to operating results presented in accordance with GAAP.

Current Quarter
Third quarter 2021 segment operating income decreased $14 million, or 1 percent, due to lower sales, partially offset by a higher segment operating margin rate. Third quarter 2020 segment operating income from the IT services business was $69 million. Lower operating income at Defense Systems, principally due to the impact of the IT services divestiture, and Aeronautics Systems was partially offset by higher operating income at Space Systems. Segment operating margin rate increased to 11.9 percent from 11.5 percent due to higher operating margin rates at Mission Systems, Defense Systems and Space Systems, partially offset by a lower operating margin rate at Aeronautics Systems.
Year to Date
Year to date 2021 segment operating income increased $200 million, or 7 percent, due to higher sales and a higher segment operating margin rate. Higher operating income at Space Systems and Mission Systems was partially offset by lower operating income at Defense Systems due to the impact of the IT services divestiture. Year to date 2021 segment operating income from the IT services business was $20 million as compared to $180 million in the prior year period. Year to date 2021 segment operating income includes a first quarter 2021 benefit of approximately $100 million due to the impact of lower overhead rates on the company’s fixed price contracts. The lower projected overhead rates were principally driven by a reduction in projected CAS pension costs as well as operational performance at the sectors, which more than offset lower business base due to the IT services divestiture. Segment operating margin rate increased to 12.0 percent from 11.5 percent and reflects higher operating margin rates at all four sectors largely as a result of the items discussed above.
FAS/CAS Operating Adjustment
Third quarter 2021 and year to date 2021 FAS/CAS operating adjustment decreased primarily due to lower CAS pension expense resulting from favorable plan asset returns in 2020 and changes in certain CAS actuarial assumptions as of December 31, 2020. Third quarter 2021 CAS pension expense also reflects a $44 million benefit from updated demographic information.

NORTHROP GRUMMAN CORPORATION                        
Unallocated Corporate (Expense) Income
Current Quarter
The decrease in third quarter 2021 unallocated corporate expense is due, in part, to a $60 million benefit from insurance settlements related to shareholder litigation involving the former Orbital ATK prior to the company’s acquisition, that was resolved in June 2019. Unallocated corporate expense also decreased due to a change in deferred state income taxes related to our methods of timing of revenue recognition and related costs as well as lower intangible asset amortization and PP&E step-up depreciation.
Year to Date
The increase in year to date 2021 unallocated corporate (expense) income is primarily due to a $2.0 billion pre-tax gain on the sale of our IT services business, partially offset by $192 million of unallowable state taxes and transaction costs associated with the divestiture. Unallocated corporate (expense) income also increased due to the current quarter items described above, as well as a net increase in deferred state tax assets related to certain state tax legislation adopted in 2020 that places temporary limitations on tax credits and a change in tax revenue recognition on certain contracts.
Net EAC Adjustments - We record changes in estimated contract earnings at completion (net EAC adjustments) using the cumulative catch-up method of accounting.

NORTHROP GRUMMAN CORPORATION                        
Year to Date
Year to date 2021 sales decreased $54 million, or 1 percent, due to lower volume at Autonomous Systems, which was partially offset by higher volume at Manned Aircraft. Lower A350 production activity, and lower volume on B-2 DMS and certain Global Hawk programs, was partially offset by higher volume on E-2 and restricted programs.
Operating Income
Current Quarter
Third quarter 2021 operating income decreased $29 million, or 10 percent, due to lower sales and a lower operating margin rate. Operating margin rate decreased to 9.7 percent from 10.1 percent principally due to a $42 million unfavorable EAC adjustment on F-35 due to labor-related production inefficiencies largely driven by COVID-19-related impacts on the labor market and employee leave. This was partially offset by higher net favorable EAC adjustments at Autonomous Systems.
Year to Date
Year to date 2021 operating income was consistent with the prior year period and operating margin rate increased to 10.1 percent from 10.0 percent principally due to higher net favorable EAC adjustments, which were largely driven by the first quarter 2021 reduction in overhead rates, partially offset by the unfavorable F-35 adjustment discussed above.

Product Sales and Costs
Current Quarter
Third quarter 2021 product sales increased $178 million, or 3 percent, primarily due to an increase in product sales at Space Systems, partially offset by decreases in product sales at Aeronautics Systems and Defense Systems. The increase at Space Systems was principally due to ramp-up on GBSD and NGI. The decrease at Aeronautics Systems was driven by lower volume on restricted programs and F-35. The decrease at Defense Systems was primarily driven by the close-out of Lake City.
Third quarter 2021 product costs increased $96 million, or 2 percent, consistent with the increase in product sales above.
Year to Date
Year to date 2021 product sales increased $1.7 billion, or 9 percent, principally due to an increase in product sales at Space Systems and Mission Systems, partially offset by a decrease at Defense Systems. The increase at Space Systems was primarily driven by higher volume on GBSD, restricted programs, Artemis, Next Gen OPIR and NGI. The increase at Mission Systems was driven by higher volume across the sector. The decrease at Defense Systems was primarily driven by the close-out of Lake City.
Year to date 2021 product costs increased $1.4 billion, or 8 percent, consistent with the higher product sales described above.
Service Sales and Costs
Current Quarter
Third quarter 2021 service sales decreased $541 million, or 22 percent, primarily due to the IT services divestiture. Third quarter 2020 sales from the IT services business, which were largely included in service sales, were $602 million. The reductions associated with the IT services divestiture were partially offset by higher volume on the CBP P-3 program at Defense Systems.
Third quarter 2021 service costs decreased $445 million, or 21 percent, consistent with the lower service sales above.
Year to Date
Year to date 2021 service sales decreased $1.3 billion, or 18 percent, primarily due to the IT services divestiture. Year to date 2021 sales from the IT services business, which were largely included in service sales, were $162 million as compared to $1.7 billion in the prior year period. The reductions associated with the IT services divestiture were partially offset by higher volume on the ROK Global Hawk CLS and CBP P-3 programs at Defense Systems.
Year to date 2021 service costs decreased $1.2 billion, or 19 percent, consistent with the lower services sales described above.
BACKLOG
Backlog represents the future sales we expect to recognize on firm orders received by the company and is equivalent to the company’s remaining performance obligations at the end of each period. It comprises both funded backlog (firm orders for which funding is authorized and appropriated) and unfunded backlog. Unexercised contract options and indefinite delivery indefinite quantity (IDIQ) contracts are not included in backlog until the time an option or IDIQ task order is exercised or awarded. Backlog is converted into sales as costs are incurred or deliveries are made.
Backlog consisted of the following as of September 30, 2021 and December 31, 2020:

New Awards
Third quarter and year to date 2021 net awards totaled $6.9 billion and $22.3 billion, respectively, and backlog totaled $74.8 billion. Significant third quarter new awards include $1.8 billion for restricted programs, principally at Space and Mission Systems, $0.9 billion for NASA’s Habitation and Logistics Outpost (HALO) module and $0.5 billion for F-35. In connection with the IT services divestiture, the company reduced backlog by $1.4 billion during the first quarter of 2021 ($1.0 billion at Defense Systems, $0.2 billion at Mission Systems and $0.2 billion at Space Systems).
LIQUIDITY AND CAPITAL RESOURCES
We endeavor to ensure efficient conversion of operating income into cash and to increase shareholder value through cash deployment activities. In addition to our cash position, we use various financial measures to assist in capital deployment decision-making, including cash provided by operating activities and adjusted free cash flow, a non-GAAP measure described in more detail below.
At September 30, 2021, we had $4.1 billion in cash and cash equivalents. Effective January 30, 2021, we completed the IT services divestiture for $3.4 billion cash. Proceeds were primarily used in the first quarter of 2021 for a $2.0 billion accelerated share repurchase and to fund redemption of $1.5 billion of the company’s 2.55 percent unsecured notes due October 2022. In April 2021, we renewed our one-year $500 million uncommitted credit facility.
The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) established a program with provisions to allow U.S. companies to defer the employer’s portion of social security taxes between March 27, 2020 and December 31, 2020 and pay such taxes in two installments in 2021 and 2022. Our first installment of deferred social security taxes of approximately $200 million is due in the fourth quarter of 2021. Under Section 3610, the CARES Act also authorized the government to reimburse qualifying contractors for certain costs of providing paid leave to employees as a result of COVID-19. The company continues to seek, and anticipates continuing to seek, recovery for certain COVID-19-related costs under Section 3610 of the CARES Act and through our contract provisions, though it is unclear how much we will be able to recover. In addition, the U.S. Department of Defense (DoD) has, to date, taken steps to increase the rate for certain progress payments from 80 percent to 90 percent for costs incurred and work performed on relevant contracts.
Cash and cash equivalents and cash generated from operating activities, supplemented by borrowings under credit facilities, commercial paper and/or in the capital markets, if needed, are expected to be sufficient to fund our operations for at least the next 12 months.
Operating Cash Flow

(1)Includes depreciation and amortization, non-cash lease expense, stock based compensation expense, deferred income taxes and net periodic pension and OPB income.
Year to date 2021 cash provided by operating activities decreased $578 million principally due to $588 million of federal and state taxes paid in connection with the IT services divestiture.
Adjusted Free Cash Flow
Adjusted free cash flow, as reconciled in the table below, is a non-GAAP measure defined as net cash provided by or used in operating activities less capital expenditures, plus proceeds from the sale of equipment to a customer (not otherwise included in net cash provided by or used in operating activities) and the after-tax impact of discretionary
-32-

pension contributions. Adjusted free cash flow includes proceeds from the sale of equipment to a customer as such proceeds were generated in a customer sales transaction. It also includes the after-tax impact of discretionary pension contributions for consistency and comparability of financial performance. This measure may not be defined and calculated by other companies in the same manner. We use adjusted free cash flow as a key factor in our planning for, and consideration of, acquisitions, the payment of dividends and stock repurchases. This non-GAAP measure may be useful to investors and other users of our financial statements as a supplemental measure of our cash performance, but should not be considered in isolation, as a measure of residual cash flow available for discretionary purposes, or as an alternative to operating cash flows presented in accordance with GAAP.

Adjusted free cash flow$1,527 $1,875 (19)%
Year to date 2021 adjusted free cash flow decreased $348 million due to lower net cash provided by operating activities, partially offset by a decrease in capital expenditures and the receipt of additional proceeds from the fourth quarter 2020 sale of equipment to a customer.
Investing Cash Flow
Year to date 2021 net cash provided by investing activities was $2.8 billion compared to net cash used in investing activities of $828 million in the prior year period, principally due to $3.4 billion in cash received from the sale of our IT services business during the first quarter of 2021.
Financing Cash Flow
Year to date 2021 net cash used in financing activities was $5.8 billion compared to net cash provided by financing activities of $875 million in the prior year period, principally due to $2.7 billion of share repurchases, $2.2 billion in debt repayments and $737 million of dividends paid in the current year period as compared to $2.2 billion of net proceeds from the issuance of long-term debt, $490 million of share repurchases and $711 million of dividends paid in the prior year period.

These types of matters could result in administrative, civil or criminal fines, penalties or other sanctions (which terms include judgments or convictions and consent or other voluntary decrees or agreements); compensatory, treble or other damages; non-monetary relief or actions; or other liabilities. Government regulations provide that certain allegations against a contractor may lead to suspension or debarment from future government contracts or suspension of export privileges for the company or one or more of its components. The nature of legal proceedings is such that we cannot assure the outcome of any particular matter. For additional information on pending matters, please see Notes 5 and 6 to the financial statements, and for further information on the risks we face from existing and future investigations, lawsuits, arbitration, claims, enforcement actions and other legal proceedings, please see “Risk Factors” in our 2020 Annual Report on Form 10-K.
Consistent with SEC Regulation S-K Item 103, we have elected to disclose those environmental proceedings with a governmental entity as a party where the company reasonably believes such proceeding would result in monetary sanctions, exclusive of interest and costs, of $1.0 million or more.
