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.
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.
Effective January 1, 2020, the company reorganized its operating sectors to better align the company’s broad portfolio to serve its customers’ needs. The four new sectors, which also comprise our reportable segments, are Aeronautics Systems, Defense Systems, Mission Systems and Space Systems.
Beginning in the second quarter of 2020, the company no longer considers certain unallowable costs and environmental matters that are principally managed at the corporate office as part of management’s evaluation of segment operating performance. As a result, certain unallowable compensation and other costs, which were previously included in segment operating results, are now reported in Unallocated corporate expense within operating income. In addition, certain accrued and deferred costs, as well as unallowable costs, if any, associated with certain environmental matters that were previously reflected in segment assets and operating results are now reflected in corporate assets and Unallocated corporate expense within operating income. The impact of these changes are reflected in the amounts in this Form 10-Q. See Note 9 and Part II, Item 5 for further information regarding the impact of these changes on the company’s current and prior period segment operating income.
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 2019 Annual Report on Form 10-K, and the Form 8-K that we expect to filefiled with the SEC immediately after filing this Form 10-Q,on April 29, 2020, which recasts the disclosures in certain portions of the 2019 Annual Report on Form 10-K to reflect changes in the company’s reportable segments.segments, and the Quarterly Report on Form 10-Q for the quarter ended March 31, 2020.
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 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. As control is effectively transferred while we perform on our contracts, we generally recognize revenue over time using the cost-to-cost method (cost incurred relative to total cost estimated at completion) as the company believes this represents the most 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

-5-

NORTHROP GRUMMAN CORPORATION                        

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.

Table of Contents

NORTHROP GRUMMAN CORPORATION                        

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)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 (G&A) costs, is charged against income in the period the loss is identified.
The following table presents the effect of aggregate net EAC adjustments:

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. No such adjustments were material to the financial statements during the three months ended March 31,June 30, 2020 and 2019.
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 March 31,June 30, 2020 was $64.2$70.0 billion. We expect to recognize approximately 4540 percent and 7065 percent of our March 31,June 30, 2020 backlog as revenue over the next 12 and 24 months, respectively, 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 six months ended MarchJune 30, 2020 that was included in the December 31, 20202019 contract liability balance was $442 million and $1.2 billion, respectively. The amount of revenue recognized for the three and six months ended June 30, 2019 that was included in the December 31, 2018 contract liability balances at the beginning of each yearbalance was $781$333 million and $674 million,$1.0 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.

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 March 31,June 30, 2020, 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 0.70.4 million shares and 0.70.6 million shares for the three and six months ended March 31,June 30, 2020, respectively. The dilutive effect of these securities totaled 0.6 million shares for the three and 2019, respectively.six months ended June 30, 2019.

The firstsecond quarter 2020 effective tax rate of 16.5 percent was generally comparable to the prior year period. The company’s second quarter 2020 effective tax rate includes $48 million of research credits, as compared to $51 million in the prior year period.
Year to Date
The year to date 2020 effective tax rate increased to 17.617.0 percent from 16.516.4 percent in the first quarter of 2019prior period primarily due to nondeductible losses on marketable securities and an increase in reserves for uncertain tax positions.

In March 2020, the Coronavirus Aid, Relief, and Economic SecurityCARES Act (the “CARES Act”) was enacted. The CARES Act includes certain changes to U.S. tax law that impact the company, including a technical correction to the 2017 Tax Cuts and Jobs Act, which makes certain qualified improvement property eligible for bonus depreciation. The CARES Act did not have a significant impact on the company’s firstsecond quarter and year to date 2020 effective tax rate.
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 Act. It is reasonably possible that within the next 12 months our unrecognized tax benefits related to these matters may decrease by up to $60$70 million. Since enactment of the 2017 Tax Act, the IRSInternal Revenue Service (IRS) and U.S. Treasury Department have issued and are expected to further issue interpretive guidance that impacts taxpayers. We will continue to evaluate such guidance as it is issued.
We file income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions.

4.    FAIR VALUE OF FINANCIAL INSTRUMENTS
The company holds a portfolio of marketable securities consisting of 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 derivative fair values and related unrealized gains/losses at March 31,June 30, 2020 and December 31, 2019 were not material. There were no transfers of financial instruments between the three levels of the fair value hierarchy during the threesix months ended March 31,June 30, 2020.
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 $17.5$19.0 billion and $15.1 billion as of March 31,June 30, 2020 and December 31, 2019, 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 carrying value of long-term debt was $16.1 billion and $13.9 billion as of March 31,June 30, 2020 and December 31, 2019, respectively. The current portion of long-term debt is recorded in Other current liabilities in the unaudited condensed consolidated statements of financial position.
Unsecured Senior Notes
In March 2020, the company issued $2.25 billion of unsecured senior notes for general corporate purposes, including debt repayment and working capital, as follows:
$750 million of 4.40% senior notes due 2030 (the “2030 Notes”),
$500 million of 5.15% senior notes due 2040 (the “2040 Notes”) and
$1.0 billion of 5.25% senior notes due 2050 (the “2050 Notes”).
We refer to the 2030 Notes, the 2040 Notes and the 2050 Notes, together, as the “notes.” Interest on the notes is payable semi-annually in arrears. The notes are generally subject to redemption, in whole or in part, at the company’s discretion at any time, or from time to time, prior to maturity at a redemption price equal to the greater of 100% of the principal amount of the notes to be redeemed or an applicable “make-whole” amount, plus accrued and unpaid interest.
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 have been delivered. The company’s lawsuit is based on various theories of liability. The complaint 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. 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 April 2, 2013, the U.S. Department of Justice informed the company of a False Claims Act complaint relating to the FSS contract that was filed under seal by a relator in June 2011 in the U.S. District

Court for the Eastern District of Virginia. On June 3, 2013, the United States filed a Notice informing the Court that the United States had decided not to intervene in this case. The relator alleged that the company violated the False Claims Act in a number of ways with respect to the FSS contract, alleged damage to the USPS in an amount of at least approximately $179 million annually, alleged that he was improperly discharged in retaliation, and sought an unspecified partial refund of the contract purchase price, penalties, attorney’s fees and other costs of suit. The relator later voluntarily dismissed his retaliation claim and reasserted it in a separate arbitration, which he also ultimately voluntarily dismissed. On September 5, 2014, the court granted the company’s motion for summary judgment and ordered the relator’s False Claims Act case be dismissed with prejudice. On February 16, 2018, both the company and the United States filed motions to dismiss many of the claims and counterclaims referenced above, in whole or in part. The United States also filed a motion seeking to amend its answer and counterclaim, including to reduce its counterclaim to approximately $193 million, which the court granted on June 11, 2018. On October 17, 2018, the court granted in part and denied in part the parties’ motions to dismiss. On February 3, 2020, the parties commenced what was expected to be a seven-week trial. The first four weeks of trial have concluded, but the court postponed the remaining estimated three weeks until May 2020 as a result of COVID-19-related concerns. Trial is currently scheduled to resume in October 2020. Although the ultimate outcome of these matters (“the FSS matters,” collectively), including any possible loss, cannot be predicted or reasonably estimated at this time, the company intends vigorously to pursue and defend the FSS matters.

On August 8, 2013, the company received a court-appointed expert’s report in litigation pending in the Second Federal Court of the Federal District in Brazil brought by the Brazilian Post and Telegraph Corporation (ECT), a Brazilian state-owned entity, against Solystic SAS (Solystic), a French subsidiary of the company, and 2 of its consortium partners. In this suit, commenced on December 17, 2004, ECT alleges the consortium breached its contract with ECT and seeks damages of approximately R$111 million (the equivalent of approximately $22$20 million as of March 31,June 30, 2020), plus interest, inflation adjustments and attorneys’ fees, as authorized by Brazilian law, which amounts could be significant over time. The original suit sought R$89 million (the equivalent of approximately $17$16 million as of March 31,June 30, 2020) in damages. In October 2013, ECT asserted an additional damage claim of R$22 million (the equivalent of approximately $4 million as of March 31,June 30, 2020). In its counterclaim, Solystic alleges ECT breached the contract by wrongfully refusing to accept the equipment Solystic had designed and built and seeks damages of approximately €31 million (the equivalent of approximately $34$35 million as of March 31,June 30, 2020), plus interest, inflation adjustments and attorneys’ fees, as authorized by Brazilian law. The Brazilian court retained an expert to consider certain issues pending before it. On August 8, 2013 and September 10, 2014, the company received reports from the expert, which contain some recommended findings relating to liability and the damages calculations put forth by ECT. Some of the expert’s recommended findings were favorable to the company and others were favorable to ECT. In November 2014, the parties submitted comments on the expert’s most recent report. On June 16, 2015, the court published a decision denying the parties’ request to present oral testimony. In a decision dated November 13, 2018, the trial court ruled in ECT’s favor on one of its claims against Solystic, and awarded damages of R$41 million (the equivalent of approximately $8 million as of March 31,June 30, 2020) against Solystic and its consortium partners, with that amount to be adjusted for inflation and interest from November 2004 through any appeal, in accordance with the Manual of Calculations of the Federal Justice, as well as attorneys’ fees. On March 22, 2019, ECT appealed the trial court’s decision to the intermediate court of appeals. Solystic filed its appeal on April 11, 2019. The parties are assessing whether there ishave executed a possible pathsettlement agreement in this matter and have filed it with the court for a negotiated resolution of the dispute.approval.
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, the New York State Department of Health and other federal, state and local governmental authorities, to address legacy environmental conditions in Bethpage. We have incurred, and expect to continue to incur, as included in Note 6, substantial remediation costs related to these environmental conditions. The remediation standards or requirements to which we are subject are being reconsidered and may changeare changing and costs may increase materially. As discussed in Note 6, the State of New York issued a Feasibility Study and an Amended Record of Decision, seeking to impose additional remedial requirements. The company is engaged in discussions with the State of New York and certain other potentially responsible parties. The State of New York has said that, among other things, it is also evaluating potential natural resource damages. In addition, we are a party to various, and expect to become a party to additional, legal proceedings and disputes related to remediation, costs, allowability and/or alleged environmental impacts in Bethpage, including with federal and state entities (including the Navy, Defense Contract Management Agency, the state, local municipalities and water districts,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 (including natural resource damages), determinations on allocation, allowability and coverage, and non-monetary relief. 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 March 31,June 30, 2020, 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 March 31,June 30, 2020, or its annual results of operations and/or cash flows.
Recently, the U.S. government has raised questions about an interest rate assumption used by the company to determine our CAS pension costexpense in previous years.years and in our current forward pricing rate proposal. 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 are currently engaging with the government to address their questions. Althoughquestions, and are preparing our formal response, which we believe our pension-relateddemonstrates the appropriateness of the assumptions are appropriate,used. However, 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 March 31,June 30, 2020 and December 31, 2019:

(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 March 31,June 30, 2020, $131$144 million is deferred in Prepaid expenses and other current assets and $308$334 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 March 31,June 30, 2020, or its annual results of operations and/or cash flows. With respect to Bethpage, the State of New York issued a Feasibility Study and an Amended Record of Decision, proposing to impose additional remedial requirements.

9.    SEGMENT INFORMATION
Effective January 1, 2020, the company reorganized its operating sectors to better align the company’s broad portfolio to serve its customers’ needs. The 4 new sectors, which also comprise our reportable segments, are Aeronautics Systems, Defense Systems, Mission Systems and Space Systems.
As discussed in Note 1, beginning in the second quarter of 2020, the company no longer considers certain unallowable costs as part of management’s evaluation of segment operating performance. As a result, certain unallowable costs, which were previously included in segment operating results, are now reported in Unallocated corporate expense within operating income. This change has been applied retrospectively in the amounts below.

Net FAS (Service)/CAS Pension 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 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
Unallocated corporate expense 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 a portion of management and administration, legal, environmental, compensation, retiree benefits, advertising and other corporate unallowable costs. Unallocated corporate expense also includes costs not considered part of management’s evaluation of segment

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 March 31,June 30, 2020, and the related condensed consolidated statements of earnings and comprehensive income cash flows and changes in shareholders’ equity for the three-month and six-month periods ended March 31,June 30, 2020 and 2019, and of cash flows for the six-month periods ended June 30, 2020 and 2019, 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, 2019, 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 29, 2020, 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, 2019, 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; hypersonics; 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 foreign, state and local governments, as well as commercial customers.
The following discussion should be read along with the financial statements included in this Form 10-Q, as well as our 2019 Annual Report on Form 10-K, and the Form 8-K that we expect to filefiled with the SEC immediately after filing this Form 10-Q,on April 29, 2020, which recasts the disclosures in certain portions of the 2019 Annual Report on Form 10-K to reflect changes in the company’s reportable segments.segments, and the Quarterly Report on Form 10-Q for the quarter ended March 31, 2020. These documents provide additional information on our business and the environment in which we operate and our operating results.
COVID-19
Coronavirus disease 2019 (“COVID-19”) was first reported in late 2019 and has since dramatically impacted the global health and economic environment, including millions of confirmed cases, business slowdowns or shutdowns, government challenges and market volatility. In March 2020, the World Health Organization characterized COVID-19 as a global pandemic, and the President declared a national emergency concerning the COVID-19 outbreak. The company’s leadership, our crisis management and Crisis Management Teams havebusiness resumption teams, and local site leadership continue closely monitoredto monitor and address the developments, including the impact on our company, our employees, our customers, our suppliers and our communities. They haveThe company has considered and continues to consider guidance from the Centers for Disease Control (CDC), other health organizations, governments and our customers.customers, among others. We have taken, and continue to take, robust actions to help protect the health, safety and well-being of our employees, to support our suppliers and local communities, and to continue to serve our customers. Our goals have been to lessen the immediate potential adverse impacts, both health and economic, and to continue to position the company for long-term success. Like the communities in which we serve, our actions have varied depending on the spread of COVID-19 and local health requirements, the needs of our employees and the needs of our business. Among other actions, we have required or enabled employees to work from home or remotely where practicable, and expanded IT and communication support to enhance their productivity; adjusted work spaces and shift schedules to facilitate social distancing for those who continue to work in our facilities; implemented visitor protocols and enhanced cleaning and disinfecting procedures at our facilities; required face coverings and worked to procure and distribute personal protective equipment (“PPE”); implemented health checks and visitor protocols; restricted travel; provided additional benefits including paid time off for those most at risk; and contributed financial and manufacturing resources to supporting critical national requirements, such as for PPE. Along with the Northrop Grumman Foundation, we have provided grants for global, national and local organizations that support frontline healthcare workers, address food insecurity, advance efforts for vaccines, increase student access to technology and provide support to vulnerable populations; donated PPE items to emergency response teams and healthcare professionals, including N95 masks and Tyvek suits; and established a COVID-19 relief matching gift program for employees.
As a result ofEarlier in the COVID-19 pandemic, many state and local jurisdictions have implemented mandatory stay-at-home or shelter-in-place orders. To date, mostMost of those orders have exempted some or all of the defense industrial base, including Northrop Grumman and many of our suppliers, as part of the essential or critical infrastructure. Our facilities have largely remained open and many of our employees who cannot work remotely are continuing to come to work and support our customers’ national security and mission-essential operations. More recently, state and local jurisdictions started to lift mandatory stay-at-home or shelter-in-place orders and started gradually to ease restrictions. We started to implement return to office plans to allow some employees who had been working remotely slowly to return to the workplace. At our facilities, we generally saw employee absenteeism decrease and productivity increase during the second quarter. Most recently, as cases have resurged in parts of our country, including areas in which we maintain large facilities, we have seen governments slow or reverse efforts to reopen or shift into later phases of recovery, with increased risks to our operations. Throughout, we have worked to adapt and to take robust actions to protect the health, safety and well-being of our employees and to serve our customers, considering, among other things, state and local requirements and guidance from the CDC. We have also taken various steps in efforts to support our

Even though we have been able to continue many of our operations, we have experienced and expect to continue to experience certain increasingincreased costs to maintain our operations and address reductions in productivity, including as a result of actions to protect health; because of illness, quarantines, and absenteeism; as a result of government actions; and because of disruption and stress among our suppliers and customers. We continue to monitor this situation closely and cannot predict how it will change.change, including the extent of any increase in the number of COVID-19 cases and the costs and impacts to us. Our customers have generally continued to make timely payments, and we are working with them to consider the possibility of additional cost recoveries.

U.S. Political and Economic Environment
Since the filing of our 2019 Annual Report on Form 10-K, the President released his budget request for fiscal year 2021 (FY21) on February 10, 2020. The FY21 budget request includes $746 billion for national security, which will be the subject of debate in Congress. The FY21 budget request addresses various capabilities highlighted in the U.S. National Security Strategy, the National Defense Strategy and the Missile Defense Review. We believe our capabilities, particularly in space, missiles, missile defense, hypersonics, counter-hypersonics, survivable aircraft and cybermission systems will continue to allow for long-term profitable growth in our business in support of our customers’ needs. Congress has enacted emergency COVID-19 relief bills addressing certain impacts of the pandemic.pandemic and is continuing to consider other responses to the COVID-19 crisis.

Operating Income and Margin Rate
FirstCurrent Quarter
Second quarter 2020 operating income increased $48 million, or 5 percent, primarily due to an increase in segment operating income and lower unallocated corporate expense. Second quarter 2020 operating margin rate of 11.2 percent was comparable to the prior year period. First quarter 2020 operating margin rate declined to 10.8 percent reflecting lower segment operating margins at Aeronautics Systems and Defense Systems, partially offset by a decrease in unallocated corporate expense.

SEGMENT OPERATING RESULTS
Basis of Presentation
Effective January 1, 2020, the company reorganized its operating sectors to better align the company’s broad portfolio to serve its customers’ needs. The four new sectors, which also comprise our reportable segments, are Aeronautics Systems, Defense Systems, Mission Systems and Space Systems. This realignment is reflected in the accompanying financial information.

Table of Contents

NORTHROP GRUMMAN CORPORATION                        

Beginning in the second quarter of 2020, the company no longer considers certain unallowable costs as part of management’s evaluation of segment operating performance. As a result, certain unallowable costs, which were previously included in segment operating results, are now reported in Unallocated corporate expense within operating income. This change has been applied retrospectively in the accompanying financial information. See Notes 1 and 9 to the financial statements and Part II, Item 5 for further information regarding the impact of this change on the company’s current and prior period segment information.
We present our sectors in the following business areas, which are reported in a manner reflecting core capabilities:
Aeronautics Systems Defense Systems Mission Systems Space Systems
Autonomous Systems Battle Management & Missile Systems Airborne Sensors & Networks Launch & Strategic Missiles
Manned Aircraft Mission Readiness Cyber & Intelligence Mission Solutions Space
    Maritime/Land Systems & Sensors  
    Navigation, Targeting & Survivability  
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 expense and unallocated corporate items (certain corporate-level expenses, which are not considered allowable or allocable under 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.

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 March 31,June 30, 2020 and December 31, 2019:

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 used inprovided by operating activities and free cash flow, a non-GAAP measure described in more detail below.
At March 31,June 30, 2020, we had $3.3$4.2 billion in cash and cash equivalents. In March 2020, we issued $2.25 billion of unsecured senior notes to help preserve financial flexibility in light of uncertainty resulting from the COVID-19 pandemic. We intend to use those proceeds for general corporate purposes, which may include debt repayment and working capital. In April 2020, we entered into a one-year $500 million uncommitted credit facility to provide an additional source of potential financing.
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. The CARES Act also provided for a deferral of certain estimated income tax payments by extending the deadline for amounts due in the second quarter to July 15, 2020. 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 has begun

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. 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. We expect both ofbelieve these actions should helpcontinue to mitigate COVID-19 relatedsome COVID-19-related negative impacts to our operating cash flows forduring the remainder of the year.
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.

Free Cash Flow
Free cash flow, as reconciled in the table below, is a non-GAAP measure defined as net cash used inprovided by operating activities less capital expenditures, and may not be defined and calculated by other companies in the same manner. We use 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.

PART II. OTHER INFORMATION
Item 1. Legal Proceedings
We have provided information about certain legal proceedings in which we are involved in Notes 5 and 6 to the financial statements.
We are a party to various investigations, lawsuits, arbitration, claims, enforcement actions and other legal proceedings, including government investigations and claims, that arise in the ordinary course of our business. 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 2019 Annual Report on Form 10-K.
Environmental Matters Involving Potential Monetary Damages in Excess of $100,000
The following environmental matter is reported pursuant to SEC Regulation S-K Item 103 because it involves potential monetary damages in excess of $100,000. In June 2016, the U.S. Environmental Protection Agency (EPA) conducted an environmental inspection at the Allegheny Ballistics Laboratory in Rocket Center, WV, which was then and is now operated by Alliant Techsystems Operations LLC (“ATO”). ATO became an indirect subsidiary of the Company approximately 2 years later, in June 2018. On March 3, 2020, EPA notified ATO of a proposed penalty for alleged noncompliance with certain air emission, water discharge and waste management permitting and regulatory requirements. EPA proposed a civil penalty totaling $497,635 and certain non-monetary actions. The Company disputeshas disputed the allegations and is in discussions with the government.
Item 1A. Risk Factors
The following updates and supplementsThere have been no material changes to our risk factors since our 2019 Annual Report on Form 10-K, except with respect to the risk factors describedfactor regarding COVID-19 that the company included in the section entitled “Risk Factors” in our 2019 Annual Report on Form 10-K, as updated by the Current Report on Form 8-K filed on March 19, 2020. It should be read in conjunction with the risk factors in the 2019 Annual Report on Form 10-K. In addition to the other information set forth in this Quarterly Report on Form 10-Q you should carefully considerfor the factors discussed in Part I, Item 1A Risk Factors in the 2019 Form 10-K which could materially affect our business, financial condition or future results. The COVID-19 pandemic has heightened, and in some cases manifested, certain of the risks we normally face in operating our business, including those disclosed in the 2019 Form 10-K, and the risk factor disclosure in the 2019 Form 10-K is qualified by the information relating to COVID-19 that is described in this Quarterly Report on Form 10-Q, including the updated risk factor set forth below. Except as otherwise described herein, there have been no other material changes from the risk factors previously disclosed in the 2019 Form 10-K.
We face various risks related to health epidemics, pandemics and similar outbreaks, which may have material adverse effects on our business, financial position, results of operations and/or cash flows.
We face various risks related to health epidemics, pandemics and similar outbreaks, including the global outbreak of coronavirus disease 2019 (“COVID-19”). Since first reported in late 2019, the COVID-19 pandemic has dramatically impacted the global health and economic environment, including millions of confirmed cases, business slowdowns or shutdowns, government challenges and market volatility of an unprecedented nature. Although we have, to date, managed to continue most of our operations, we cannot predict the future course of events nor can we assure that this global pandemic, including its economic impact, will not have a material adverse impact on our business, financial position, results of operations and/or cash flows. (For further information relating to our company’s experience to date, and certain steps taken to approach the risks presented by the COVID-19 pandemic, see Management’s Discussion and Analysis of Financial Condition and Results of Operations).
If significant portions of our workforce are unable to work effectively, including because of illness, quarantines or absenteeism; steps the company has taken to protect health and challenges with additional steps (such as securing personal protective equipment and testing); government actions; facility closures; work slowdowns or stoppages; limited supplies or resources; or other circumstances related to COVID-19, our operations will be further impacted. We may be unable to perform fully on our contracts and we may incur liabilities and suffer losses as a result. In addition, we will continue to incur additional costs as a result of the COVID-19 outbreak, including to protect the well-being of our employees, which will likely not be fully recoverable. The continued spread of COVID-19 may

-29-

Table of Contents

NORTHROP GRUMMAN CORPORATION                        

also affect our ability to hire, develop and retain our talented and diverse workforce, and to maintain our corporate culture.
The continued spread of COVID-19, including the global pandemic and the economic impact, are likely also to cause further disruption in our supply chain. If our suppliers have increased challenges with their workforce (including as a result of illness, absenteeism or government orders), access to necessary components and supplies, access to capital, and access to fundamental support services (such as shipping and transportation), they may be unable to provide the agreed-upon goods and services in a timely, compliant and cost-effective manner. We may incur additional costs and delays in our business, including as a result of higher prices, schedule delays or the need to identify and develop alternative suppliers, and we may need to provide additional resources to support our suppliers or otherwise continue performance under our contracts. In some instances, we may be unable to do that, incurring additional liabilities under our current contracts and hampering new ones.
The global COVID-19 crisis is putting extraordinary pressures on the U.S. government and governments around the world. It could cause delays or limits in the ability of the government and other customers to perform, including making timely payments and awards to us, negotiating contracts and agreeing appropriate costs for recovery, performing quality inspections, supporting testing, accepting delivery, approving security clearances (for individuals and facilities), and providing necessary personnel, equipment and facilities. In addition, as a result of the COVID-19 crisis, there may be changes in our customers’ priorities and practices, as our customers in both the United States and globally confront competing budget priorities and more limited resources. These changes may impact current and future programs, government payments and other practices, procurements, and funding decisions.
While we have significant sources of cash and liquidity and access to committed and uncommitted credit lines, a prolonged period of generating lower cash from operations could adversely affect both our financial condition and the achievement of our strategic objectives. Additionally, there can be no assurance that we will not face credit rating downgrades, and such downgrades could adversely affect our cost of funds, liquidity and access to capital markets. The current market volatility will likely also impact investment performance and our expected asset valuations and returns, which can materially impact the calculation of long-term liabilities such as our pension obligations.
We continue to work with our stakeholders (including customers, employees, suppliers and local communities) in an effort to address responsibly this global pandemic. We continue to monitor the situation, to assess further possible implications to our business, supply chain and customers, and to take certain actions in an effort to mitigate various adverse consequences.
We expect that the longer the COVID-19 pandemic, including its economic disruption, continues, the greater the adverse impact on our business operations, financial performance and results of operations will be. Given the tremendous uncertainties and variables, we cannot at this time predict the impact of the global COVID-19 pandemic, but it could have a material adverse impact on our business, financial position, results of operations and/or cash flows.quarter ended March 31, 2020.

Item 5. Other Information
As discussed in Notes 1 and 9 to the financial statements, beginning in the second quarter of 2020, the company no longer considers certain unallowable costs as part of management’s evaluation of segment operating performance. As a result, certain unallowable costs, which were previously included in segment operating results, are now reported in Unallocated corporate expense within operating income.
The following tables summarize the effect of this change on our segment information for the three months ended March 31, 2020, December 31, 2019, September 30, 2019, June 30, 2019 and March 31, 2019 and the years ended December 31, 2019, 2018 and 2017. This change has no impact on consolidated operating results. The tables should be read in conjunction with the information contained in the company’s 2019 Annual Report on Form 10-K and the Form 8-K that we filed with the SEC on April 29, 2020, which recasts the disclosures in certain portions of the 2019 Annual Report on Form 10-K to reflect changes in the company’s reportable segments.
