NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

1. BASIS OF PRESENTATION

Principles of Consolidation and Reporting

These unaudited condensed consolidated financial statements include the accounts of Northrop Grumman Corporation and its subsidiaries (herein referred to as “Northrop Grumman,” the “company,” “we,” “us,” or “our”). Material 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 unaudited condensed consolidated financial statements are prepared in accordance with the rules of the Securities and Exchange Commission (SEC) for interim reporting. These 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 unaudited condensed consolidated financial statements are not necessarily indicative of results that may be expected for the entire year. These unaudited condensed consolidated financial statements should be read in conjunction with the information contained in the company’s Annual Report on Form 10-K for the year ended December 31, 2016 (2016 Annual Report on Form 10-K).

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

These unaudited condensed consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP” or “FAS”). The preparation thereof 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. In accounting for these contracts, we utilize either the cost-to-cost method or the units-of-delivery method of percentage-of-completion accounting, with cost-to-cost being the predominant method. The company estimates profit on contracts as the difference between total estimated sales and total estimated cost at completion and recognizes that profit either as costs are incurred (cost-to-cost) or as units are delivered (units-of-delivery). The company classifies sales as product or service depending upon the predominant attributes of the contract.

Contract sales may include estimated amounts not contractually agreed to or yet funded by the customer, including cost or performance incentives (such as award and incentive fees), un-priced change orders, contract claims and requests for equitable adjustment (REAs). Further, as contracts are performed, change orders can be a regular occurrence and may be un-priced until negotiated with the customer. Un-priced change orders, contract claims (including change orders unapproved as to both scope and price) and REAs are included in estimated contract sales when management believes it is probable the un-priced change order, claim and/or REA will result in additional contract revenue and the amount can be reliably estimated based on the facts and circumstances known to us at the time. Amounts recognized related to claims and REAs as of June 30, 2017 were not material individually or in aggregate.

Net Estimate-At-Completion (EAC) Adjustments - We recognize changes in estimated contract sales or costs and the resulting changes in contract operating margins using the cumulative catch-up method of accounting. This method recognizes, in current period operating margin, the cumulative effect of the changes on current and prior periods as net EAC adjustments; sales and operating margins in future periods of contract performance are recognized as if the revised estimates had been used since contract inception. If it is determined that a loss will result from the performance of a contract, the entire amount of the estimable future loss, including an allocation of general and administrative costs, is charged against income in the period the loss is identified. Each loss provision is first offset

against costs included in unbilled accounts receivable or inventoried costs; remaining amounts are reflected in current liabilities.

Significant EAC adjustments on a single contract could have a material effect on the company’s unaudited condensed consolidated financial position or results of operations. When such adjustments occur, we generally disclose the nature, underlying conditions and financial impact of the adjustments. No discrete event or adjustment to an individual contract was material to the accompanying unaudited condensed consolidated financial statements.

The following table presents the effect of aggregate net EAC adjustments:

Operating Income	$	98	$	137	$	213	$	266

Diluted earnings per share⁽¹⁾	0.36		0.49		0.78		0.95


⁽¹⁾	Based on statutory tax rates

Accumulated Other Comprehensive Loss

The components of accumulated other comprehensive loss are as follows:



$ in millions	June 30, 2017			December 31, 2016
Unamortized benefit plan costs, net of tax benefit of $3,317 in 2017 and $3,439 in 2016	$	(5,215	)	$	(5,416	)
Cumulative translation adjustment	(132		)	(132		)
Net unrealized gain on marketable securities and cash flow hedges, net of tax	5			2
Total accumulated other comprehensive loss	$	(5,342	)	$	(5,546	)

Unamortized benefit plan costs consist primarily of net after-tax actuarial losses totaling $5.3 billion and $5.6 billion as of June 30, 2017 and December 31, 2016, respectively. Net actuarial gains or losses are re-determined annually or upon remeasurement events and principally arise from changes in the interest rate used to discount our benefit obligations and differences between expected and actual returns on plan assets.

Reclassifications from accumulated other comprehensive loss to net earnings related to the amortization of benefit plan costs were $100 million and $199 million, net of taxes, for the three and six months ended June 30, 2017, respectively, and were $100 million and $201 million, net of taxes, for the three and six months ended June 30, 2016, respectively. The reclassifications represent the amortization of net actuarial losses and prior service credits, and are included in the computation of net periodic pension cost. See Note 8 for further information.

Reclassifications from accumulated other comprehensive loss to net earnings, relating to cumulative translation adjustments, marketable securities and effective cash flow hedges were not material for the three and six months ended June 30, 2017 and 2016.

Related Party Transactions

For all periods presented, the company had no material related party transactions.

Accounting Standards Updates

On March 10, 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2017-07 Compensation Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. ASU 2017-07 requires employers that sponsor defined benefit pension and/or other post-retirement benefit plans to report the service cost component of net benefit cost in the same line item as other compensation costs arising from services rendered by the pertinent employees during the period. Employers are required to present the other components of net benefit costs in the income statement separately from the service cost component and outside a subtotal of income from operations. Additionally, only the service cost component of net periodic pension cost will be eligible for asset capitalization.

We expect adoption of ASU 2017-07 to result in a change in our net FAS/CAS pension adjustment within operating income, which will be offset by a corresponding change in other, net to reflect the impact of presenting the interest cost, expected return on plan assets, and amortization of prior service credit and net actuarial loss components of net

NORTHROP GRUMMAN CORPORATION

periodic benefit costs outside of operating income. We expect to adopt ASU 2017-07 on January 1, 2018 using the retrospective method and do not anticipate a material change to our 2017 net FAS/CAS pension adjustment or other, net when they are recast to reflect the standard. We also do not expect ASU 2017-07 to have a material impact on our consolidated statements of financial position and/or cash flows.

On February 25, 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). ASU 2016-02 supersedes existing lease guidance, including Accounting Standards Codification (ASC) 840 - Leases. Among other things, ASU 2016-02 requires recognition of a right-of-use asset and liability for future lease payments for contracts that meet the definition of a lease and requires disclosure of certain information about leasing arrangements. ASU 2016-02 will be effective January 1, 2019, although early adoption is permitted, and it is to be applied using a modified retrospective approach. We expect to adopt the standard on January 1, 2019. We are reviewing our leases to determine the effect ASU 2016-02 will have on the company’s consolidated financial position, annual results of operations and/or cash flows. We currently expect the right-of-use assets and lease liabilities recognized upon adoption will each approximate our future minimum lease payments, as disclosed in our 2016 Annual Report on Form 10-K. We do not expect ASU 2016-02 to have a material impact on our annual results of operations and/or cash flows.

On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. ASU 2014-09 supersedes existing revenue recognition guidance, including ASC 605-35, Revenue Recognition - Construction-Type and Production-Type Contracts, and outlines a single set of comprehensive principles for recognizing revenue under U.S. GAAP. Among other things, it requires companies to identify contractual performance obligations and determine whether revenue should be recognized at a point in time or over time. On July 9, 2015, the FASB approved a one year deferral of the effective date of ASU 2014-09 to annual reporting periods beginning after December 15, 2017. ASU 2014-09 may be applied either retrospectively or through the use of a modified-retrospective method. We expect to adopt the standard on January 1, 2018 and apply it retrospectively to all periods presented.

During 2016, we substantially completed our evaluation of ASU 2014-09, including the expected impact on our business processes, systems and controls, and potential differences in the timing and/or method of revenue recognition for our contracts. As a result of our evaluation, we identified changes to and are modifying certain of our accounting policies and practices. We also designed and implemented specific controls over our evaluation of the impact of ASU 2014-09, including our calculation of the cumulative effect of adopting ASU 2014-09. Although we do not expect significant changes to our accounting systems or controls upon adoption of ASU 2014-09, we have modified certain of our current controls to incorporate the revisions we have made to our accounting policies and practices.

Based on our evaluation of ASU 2014-09, we currently do not expect it to have a material impact on our results of operations or cash flows in the periods after adoption. Under ASU 2014-09, revenue is recognized as control transfers to the customer. As such, revenue for our contracts will generally be recognized over time using the cost-to-cost method, which is consistent with the revenue recognition model we currently use for the majority of our contracts. For those contracts where we currently recognize revenue as units are delivered, in most cases the accounting for those contracts will change under ASU 2014-09 such that we will recognize revenue as costs are incurred. This change will generally result in an acceleration of revenue as compared with our current revenue recognition method for those contracts. In addition, for certain of our contracts, we expect the number of performance obligations to change under ASU 2014-09, which may alter the timing of revenue and margin recognition.

ASU 2014-09 also requires expanded disclosure regarding the nature, timing, and uncertainty of revenue, cash flow and customer contract balances, including how and when we satisfy our performance obligations and the relationship between revenue recognized and changes in contract balances during a reporting period. We have evaluated these disclosure requirements and are incorporating the collection of relevant data into our quarterly processes.

During the second quarter of 2017, we completed our assessment of the cumulative effect of adopting ASU 2014-09. Under the retrospective method, we expect to recognize the cumulative effect of adoption as an increase in unbilled accounts receivable, a reduction in inventoried costs and a net increase in retained earnings as of January 1, 2016. During the second quarter of 2017, we also completed our assessment of the impact of adoption on our 2016 results. We currently expect adopting ASU 2014-09 to result in an increase in revenue of approximately $200 million and a decrease in operating income of approximately $70 million for the year ended December 31, 2016. These changes principally reflect the impact of converting contracts to the cost-to-cost method of accounting as well as changes in the number of performance obligations for certain of our contracts. The impact of adopting ASU 2014-09 on our

2016 results of operations may not be indicative of the impact in future years. We will continue our evaluation of ASU 2014-09 (including how it may impact new contracts we receive as well as new or emerging interpretations of the standard) through the date of adoption.

Other accounting standards updates effective after June 30, 2017 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 1.0 million and 1.1 million shares for the three and six months ended June 30, 2017, respectively. The dilutive effect of these securities totaled 1.4 million and 1.7 million shares for the three and six months ended June 30, 2016, respectively.

Share Repurchases

On December 4, 2014, the company’s board of directors authorized a share repurchase program of up to $3.0 billion of the company’s common stock (the “2014 Repurchase Program”). Repurchases under the 2014 Repurchase Program commenced in March 2015 and were completed in March 2016. On September 16, 2015, the company’s board of directors authorized a new share repurchase program of up to $4.0 billion of the company’s common stock (the “2015 Repurchase Program”). Repurchases under the 2015 Repurchase Program commenced in March 2016 upon completion of the company’s 2014 Repurchase Program. As of June 30, 2017, repurchases under the 2015 Repurchase Program totaled $1.6 billion; $2.4 billion remained under this share repurchase authorization. By its terms, the 2015 Repurchase Program is set to expire when we have used all authorized funds for repurchases.

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.

The table below summarizes the company’s share repurchases to date under the authorizations described above:



							Shares Repurchased (in millions)

Net FAS/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/CAS pension adjustment reflects the difference between CAS pension expense included as cost in segment operating income and FAS expense included in total operating income.

Unallocated Corporate Expenses

Unallocated corporate expenses include the portion of corporate expenses not considered allowable or allocable under applicable CAS or the FAR, and therefore not allocated to the segments. Such costs consist of a portion of management and administration, legal, environmental, compensation, retiree benefits and corporate unallowable costs.

4. INCOME TAXES



	Three Months Ended June 30						Six Months Ended June 30

Effective income tax rate	31.6		%	29.2		%	24.6		%	23.7		%

Current Quarter

The company’s effective tax rate of 31.6 percent for the three months ended June 30, 2017 was higher as compared with the same period in 2016, principally due to an increase through the second quarter of 2017 in the proportion of research and development expenditures incurred for contracts that do not qualify for purposes of the research and development tax credit and higher prior year base expenditures used to calculate the research credit.

Year to Date

The company’s effective tax rate of 24.6 percent for the six months ended June 30, 2017 was higher as compared with the same period in 2016. The company’s effective tax rate for the six months ended June 30, 2017 includes $47 million of excess tax benefits related to employee share-based compensation, a $42 million benefit recognized in connection with the Congressional Joint Committee on Taxation’s approval of the Internal Revenue Service (IRS) examination of the company’s 2012-2013 tax returns and a $22 million benefit recognized for additional research credits claimed on our prior year tax returns. The company’s effective tax rate of 23.7 percent for the six months ended June 30, 2016 included $84 million of excess tax benefits related to employee share-based compensation.

We file income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. Our 2014-2015 federal tax returns are currently under IRS examination. The company believes it is reasonably possible that within the next twelve months we may resolve certain matters related to the years under examination, which may result in reductions of our unrecognized tax benefits up to $110 million and income tax expense up to $30 million.

5. FAIR VALUE OF FINANCIAL INSTRUMENTS

The company holds a portfolio of marketable securities consisting of securities that are classified as either trading or available-for-sale to partially fund non-qualified employee benefit plans. These 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 we record at fair value on a recurring basis identified by the level of inputs used to determine fair value:



	June 30, 2017						December 31, 2016
$ in millions	Level 1		Level 2		Total		Level 1		Level 2		Total
Financial Assets (Liabilities)
Marketable securities
Trading	$	327	$	1	$	328	$	321	$	2	$	323
Available-for-sale	12		—		12		7		—		7
Derivatives	—		5		5		—		8		8

The notional value of the company’s derivative portfolio at June 30, 2017 and December 31, 2016, was $150 million and $147 million, respectively. The portion of the notional value designated as cash flow hedges at June 30, 2017 was $13 million. At December 31, 2016, no portion of the notional value was designated as a cash flow hedge. The derivative fair values and related unrealized gains/losses at June 30, 2017 and December 31, 2016, were not material.

There were no transfers of financial instruments between the three levels of the fair value hierarchy during the six months ended June 30, 2017.

The carrying value of cash and cash equivalents approximates fair value.

Long-term Debt

The estimated fair value of long-term debt was $7.8 billion and $7.6 billion as of June 30, 2017 and December 31, 2016, 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 $7.1 billion as of June 30, 2017 and December 31, 2016. The current portion of long-term debt is recorded in Other current liabilities in the unaudited condensed consolidated statements of financial position.

6. INVESTIGATIONS, CLAIMS AND LITIGATION

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

NORTHROP GRUMMAN CORPORATION

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 December 19, 2014, the company filed a motion for partial summary judgment asking the court to dismiss the principal counterclaim referenced above. On June 29, 2015, the Court heard argument and denied that motion without prejudice to filing a later motion to dismiss. 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 two of its consortium partners. In this suit, commenced on December 17, 2004, and relatively inactive for some period of time, ECT alleges the consortium breached its contract with ECT and seeks damages of approximately R$111 million (the equivalent of approximately $34 million as of June 30, 2017), 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 $27 million as of June 30, 2017) in damages. In October 2013, ECT asserted an additional damage claim of R$22 million (the equivalent of approximately $7 million as of June 30, 2017). 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 $35 million as of June 30, 2017), 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. At some future point, the court is expected to issue a decision on the parties’ claims and counterclaims that could accept or reject, in whole or in part, the expert’s recommended findings.

The company is a party to various investigations, lawsuits, claims 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, and other than with respect to the FSS matters discussed separately above, the company does not believe that the outcome of any matter pending against the company is likely to have a material adverse effect on the company’s unaudited condensed consolidated financial position as of June 30, 2017, or its annual results of operations and/or cash flows.

7. COMMITMENTS AND CONTINGENCIES

U.S. Government Cost Claims

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 the 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

-11-

Table of Contents

NORTHROP GRUMMAN CORPORATION

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 the outcome of any such matters would not have a material adverse effect on its unaudited condensed consolidated financial position as of June 30, 2017, or its annual results of operations and/or cash flows.

Environmental Matters

The table below summarizes management’s estimate of the range of reasonably possible future costs for environmental remediation, the amount accrued within that range, and the deferred costs expected to be recoverable through overhead charges on U.S. Government contracts as of June 30, 2017 and December 31, 2016:



$ in millions	Range of Reasonably Possible Future Costs⁽¹⁾	Accrued Costs⁽²⁾		Deferred Costs⁽³⁾
June 30, 2017	$389 - $782	$	393	$	202
December 31, 2016	379 - 774	385		195


⁽¹⁾	Estimated remediation costs are not discounted to present value. The range of reasonably possible future costs does not take into consideration amounts expected to be recoverable through overhead charges on U.S. Government contracts.

⁽²⁾As of June 30, 2017, $124 million is recorded in other current liabilities and $269 million is recorded in other non-current liabilities.

⁽³⁾As of June 30, 2017, $73 million is deferred in inventoried costs and $129 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, we do not anticipate 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 June 30, 2017, or its annual results of operations and/or cash flows.

Financial Arrangements

In the ordinary course of business, the company uses standby letters of credit and guarantees issued by commercial banks and surety bonds issued principally by insurance companies to guarantee the performance on certain obligations. At June 30, 2017, there were $202 million of stand-by letters of credit and guarantees and $198 million of surety bonds outstanding.

Indemnifications

The company has provided indemnification for certain environmental, income tax and other potential liabilities in connection with certain of its divestitures. The settlement of these liabilities is not expected to have a material adverse effect on the company’s unaudited condensed consolidated financial position as of June 30, 2017, or its annual results of operations and/or cash flows.

Operating Leases

Rental expense for operating leases for the three and six months ended June 30, 2017 was $65 million and $154 million, respectively, and was $68 million and $159 million for the three and six months ended June 30, 2016, respectively. These amounts are net of immaterial amounts of sublease rental income.

Credit Facilities

In December 2016, a subsidiary of the company entered into a two-year credit facility, with two additional one-year option periods, in an aggregate principal amount of £120 million (the equivalent of approximately $152 million as of June 30, 2017) (the “2016 Credit Agreement”). The 2016 Credit Agreement is guaranteed by the company. At June 30, 2017, there was £110 million (the equivalent of approximately $139 million as of June 30, 2017) outstanding under this facility, which bears interest at a rate of LIBOR plus 1.10 percent. All of the borrowings outstanding under this facility mature less than one year from the date of issuance, but may be renewed under the terms of the facility. Based on our intent and ability to refinance the obligations on a long-term basis, substantially all of the borrowings are classified as non-current.

The company also maintains a five-year unsecured credit facility in an aggregate principal amount of $1.6 billion that matures in July 2020. At June 30, 2017, there was no balance outstanding under this facility.

At June 30, 2017, the company was in compliance with all covenants under its credit agreements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

Northrop Grumman Corporation

Falls Church, Virginia

We have reviewed the accompanying condensed consolidated statement of financial position of Northrop Grumman Corporation and subsidiaries (the “Company”) as of June 30, 2017, and the related condensed consolidated statements of earnings and comprehensive income for the three-month and six-month periods ended June 30, 2017 and 2016, and of cash flows and changes in shareholders’ equity for the six-month periods ended June 30, 2017 and 2016. These interim financial statements are the responsibility of the Company’s management.

We conducted our reviews in accordance with the standards of the Public Company Accounting Oversight Board (United States). 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 Public Company Accounting Oversight Board (United States), 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.

Based on our reviews, we are not aware of any material modifications that should be made to such condensed consolidated interim financial statements for them 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), the consolidated statement of financial position of Northrop Grumman Corporation and subsidiaries as of December 31, 2016, and the related consolidated statements of earnings and comprehensive income, cash flows, and changes in shareholders’ equity for the year then ended (not presented herein); and in our report dated January 30, 2017, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated statement of financial position as of December 31, 2016, is fairly stated, in all material respects, in relation to the consolidated statement of financial position from which it has been derived.

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 security company. We offer a broad portfolio of capabilities and technologies that enable us to deliver innovative products, systems and solutions for applications that range from undersea to outer space and into cyberspace. We provide products, systems and solutions in autonomous systems; cyber; command, control, communications and computers, intelligence, surveillance and reconnaissance (C4ISR); strike; 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 unaudited condensed consolidated financial statements included in this Form 10-Q, as well as our 2016 Annual Report on Form 10-K, which provides additional information on our systems, products and solutions; operating results; and liquidity.

Global Security and Economic Environment

The following is an update of events relating to the global security and economic environment since the filing of our 2016 Annual Report on Form 10-K and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2017 (2017 Quarterly Report on Form 10-Q).

The global security and economic environment continues to be impacted by uncertainty surrounding geopolitical tensions and financial instability. During the second quarter, we continued to see global and regional security threats from state and non-state actors as well as terrorist organizations and increasingly diverse regional security concerns. Any or all of these types of events could impact the global market for defense products, services and solutions.

U.S. Political and Economic Environment

The following is an update of events relating to the U.S. political and economic environment since the filing of our 2016 Annual Report on Form 10-K and our 2017 Quarterly Report on Form 10-Q.

In March 2017, the debt ceiling was reached and the Treasury Department began taking “extraordinary measures” to finance the government. If the debt ceiling is breached, 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 not making timely payments.

In May 2017, the President signed into law the FY 2017 Consolidated Appropriations Act. In total for FY 2017, Congress appropriated $524 billion in base discretionary funding for the DoD, consistent with the 2015 Bipartisan Budget Act. Congress also appropriated approximately $68 billion in Overseas Contingency Operation (OCO) funding and approximately $15 billion in additional DoD appropriations.

In May 2017, the President released his FY 2018 budget request, which seeks $575 billion for the DoD’s base budget, approximately $52 billion above the statutory caps provided for in the 2011 Budget Control Act (BCA). The President’s budget request also seeks another $65 billion in OCO funding for expeditionary needs, not capped by the BCA. It is unclear when or if an annual appropriations bill will be enacted for FY 2018 or at what levels. Failure to enact appropriations or a continuing resolution by September 30, 2017 could result in a government shutdown of unknown duration. If a prolonged government shutdown were to occur, it could result in program cancellations and/or stop work orders and could limit our ability to perform on our U.S. Government contracts and the U.S. Government’s ability to make timely payments.

Operating Performance Assessment and Reporting

We manage and assess our business based on our performance on contracts and programs (typically larger contracts or two or more closely-related contracts). We recognize sales from our portfolio of long-term contracts primarily using the cost-to-cost method of percentage of completion accounting, but in some cases we utilize the units-of-delivery method of percentage of completion accounting. As a result, sales tend to fluctuate in concert with costs incurred and units delivered across our large portfolio of contracts. Due to Federal Acquisition Regulation (FAR) rules that govern our U.S. Government business and related Cost Accounting Standards (CAS), most types of costs are allocable to U.S. Government contracts. As such, we do not focus on individual cost groupings (such as manufacturing, engineering and design labor, subcontractor, material, overhead and general and administrative (G&A) costs), as much as we do on total contract cost, which is the key driver of our sales and operating income.

In evaluating our 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

-16-

Table of Contents

NORTHROP GRUMMAN CORPORATION

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 three segments before distinguishing between products and services. Changes in sales are generally described in terms of volume, deliveries or other indicators of sales activity. Changes in margin rates are generally described in terms of performance and contract mix. For purposes of this discussion, volume generally refers to increases or decreases in sales or cost from production/service activity levels or delivery rates. 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., development, production, sustainment, etc).

Sales

Current Quarter

Sales for the three months ended June 30, 2017 increased $375 million, or 6 percent, as compared with the same period in 2016, primarily due to higher sales at Aerospace Systems.

Year to Date

Sales for the six months ended June 30, 2017 increased $686 million, or 6 percent, as compared with the same period in 2016, primarily due to higher sales at Aerospace Systems.

See “Segment Operating Results” below for further information by segment and “Product and Service Analysis” for product and service detail.

Operating Income

Current Quarter

Operating income for the three months ended June 30, 2017 increased $58 million, or 7 percent, as compared with the same period in 2016, primarily due to a $68 million increase in our net FAS/CAS pension adjustment and a $22 million increase in segment operating income, partially offset by a $31 million increase in unallocated corporate expenses. A slight decline in operating costs and expenses as a percentage of sales increased our operating margin rate to 13.4 percent from 13.3 percent in the prior year period. The higher operating margin rate was principally driven by the increase in our net FAS/CAS pension adjustment described above, partially offset by higher unallocated corporate expenses and a lower segment operating margin rate, as described in “Segment Operating Results.”

G&A as a percentage of sales for the three months ended June 30, 2017 was 10.4%, comparable with the prior year period.

Year to Date

Operating income for the six months ended June 30, 2017 increased $151 million, or 10 percent, as compared with the same period in 2016, primarily due to a $130 million increase in our net FAS/CAS pension adjustment and a $47 million increase in segment operating income, partially offset by a $27 million increase in unallocated corporate expenses. Lower operating costs and expenses as a percentage of sales increased our operating margin rate to 13.3 percent from 12.8 percent in the prior year period and was principally driven by the increase in our net FAS/CAS

Federal and Foreign Income Taxes

Current Quarter

Our effective tax rate for the three months ended June 30, 2017 was higher as compared with the same period in 2016, as discussed in Note 4 to the unaudited condensed consolidated financial statements.

Year to Date

Our effective tax rate for the six months ended June 30, 2017 was higher as compared with the same period in 2016, as discussed in Note 4 to the unaudited condensed consolidated financial statements.

While certain periods include discrete tax items that impact our effective tax rate, on an ongoing basis (absent the impact of discrete items and/or changes in federal tax legislation), we expect an annual effective tax rate of approximately 30 percent due principally to tax benefits associated with the manufacturing deduction and research credits.

Net Earnings

Current Quarter

Net earnings for the three months ended June 30, 2017 increased $35 million, or 7 percent, as compared with the same period in 2016, primarily due to the higher operating income described above and an increase in Other, net as a result of the gain on sale of an investment, partially offset by the higher effective tax rate described above.

Year to Date

Net earnings for the six months ended June 30, 2017 increased $119 million, or 11 percent, as compared with the same period in 2016, primarily due to the higher operating income described above and an increase in Other, net as a result of the gain on sale of an investment, partially offset by the higher effective tax rate described above.

Diluted Earnings Per Share

Current Quarter

Diluted earnings per share for the three months ended June 30, 2017 increased $0.30, or 11 percent, as compared with the same period in 2016. The increase is primarily due to the 7 percent increase in net earnings described above and a 3 percent reduction in weighted-average shares outstanding resulting from shares repurchased during 2016 and 2017.

Year to Date

Diluted earnings per share for the six months ended June 30, 2017 increased $0.90, or 15 percent, as compared with the same period in 2016. The increase is primarily due to the 11 percent increase in net earnings described above and a 4 percent reduction in weighted-average shares outstanding resulting from shares repurchased during 2016 and 2017.

Segment Operating Income and Margin Rate

Segment operating income, as reconciled in the Reconciliation of Segment Operating Income to Total Operating Income section below, is a non-GAAP measure that reflects total earnings from our three segments, including allocated pension expense recognized under CAS, and excluding unallocated corporate items and FAS pension expense. This measure may be useful to investors and other users of our financial statements as a supplemental measure in evaluating the financial performance and operational trends of our sectors. This measure 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 U.S. GAAP.

Segment operating margin rate	11.8		%	12.2		%			11.7		%	12.0		%

Current Quarter

Segment operating income for the three months ended June 30, 2017 increased $22 million, or 3 percent, as compared with the same period in 2016. Second quarter 2017 segment operating income includes $54 million recognized to date in connection with a claim related to certain costs incurred in prior years (the “Cost Claim”). Higher sales volume was partially offset by a lower segment operating margin rate. Segment operating margin rate decreased due to a lower segment margin rate at Aerospace Systems, partially offset by higher segment margin rates at Mission Systems and Technology Services.

Year to Date

Segment operating income for the six months ended June 30, 2017 increased $47 million, or 3 percent, as compared with the same period in 2016, and includes higher operating income at all three sectors principally due to the Cost Claim. Higher sales volume was partially offset by a lower segment operating margin rate. Segment operating margin rate decreased principally due to a lower segment margin rate at Aerospace Systems, partially offset by a higher segment margin rate at Technology Services.

Reconciliation of Segment Operating Income to Total Operating Income - The table below reconciles segment operating income to total operating income by including the impact of net FAS/CAS pension adjustments, as well as unallocated corporate expenses (certain corporate-level expenses, which are not considered allowable or allocable under applicable CAS or the FAR). See Note 3 to the unaudited condensed consolidated financial statements for further information on the net FAS/CAS pension adjustment and unallocated corporate expenses.



	Three Months Ended June 30						Six Months Ended June 30
$ in millions	2017			2016			2017			2016
Segment operating income	$	753		$	731		$	1,479		$	1,432
CAS pension expense	251			202			502			409
Less: FAS pension expense	(114		)	(133		)	(229		)	(266		)

Other	(1		)	—			(2		)	(3		)
Total operating income	$	855		$	797		$	1,687		$	1,536

The increase in net FAS/CAS pension adjustment for the three and six months ended June 30, 2017, as compared with the same periods in 2016, is due to higher CAS expense and lower FAS expense than in the prior year period. The increase in CAS expense relates to the continued phase-in of CAS harmonization, partially offset by a change in our mortality assumption as of December 31, 2016. The reduction in FAS expense was driven by our year-end 2016 FAS pension assumptions, including the noted change in our mortality assumption offset by a lower discount rate.

Unallocated corporate expenses increased for the three and six months ended June 30, 2017, as compared with the same periods in 2016, primarily due to the completion of our 2016 overhead cost submission. In addition, the prior year period benefited from a reduction in provisions for overhead costs.

Product Sales and Costs

Current Quarter

Product sales for the three months ended June 30, 2017 increased $417 million, or 11 percent, as compared with the same period in 2016, primarily due to higher product sales at Aerospace Systems and Mission Systems. Higher Aerospace Systems product sales were primarily driven by higher restricted and Triton volume, partially offset by lower NATO AGS volume. The increase at Mission Systems was principally due to higher product volume on combat avionics programs, including increased F-35 volume, and on communications programs, partially offset by lower volume on international radar programs.

Product costs for the three months ended June 30, 2017 increased $423 million, or 13 percent, as compared with the same period in 2016. The increase was consistent with the higher product sales described above and reflects a lower product margin rate at Aerospace Systems due to changes in contract mix.

Year to Date

Product sales for the six months ended June 30, 2017 increased $822 million, or 11 percent, as compared with the same period in 2016, primarily due to higher product sales at Aerospace Systems and Mission Systems.

deliveries, partially offset by lower NATO AGS volume. The increase at Mission Systems was principally due to higher product volume on combat avionics programs, including increased F-35 volume, and on communications programs, partially offset by lower volume on international radar programs.

Product costs for the six months ended June 30, 2017 increased $770 million, or 12 percent, as compared with the same period in 2016. The increase was consistent with the higher product sales described above and reflects a lower product margin rate at Aerospace Systems due to changes in contract mix.

Service Sales and Costs

Current Quarter

Service sales for the three months ended June 30, 2017 were comparable with the same period in 2016, and reflect higher service sales on Autonomous Systems programs at Aerospace Systems, partially offset by lower service volume on the KC-10 program at Technology Services.

Service costs for the three months ended June 30, 2017 decreased $29 million, or 1 percent, as compared with the same period in 2016. The decrease was consistent with the lower service sales at Technology Services described above and a higher service margin rate at Mission Systems.

Year to Date

Service sales for the six months ended June 30, 2017 decreased $49 million, or 1 percent as compared with the same period in 2016. The decrease was primarily driven by lower volume on several Cyber and ISR service programs at Mission Systems and lower service volume on the KC-10 program at Technology Services, partially offset by an increase in service sales on several Autonomous Systems and Manned Aircraft programs at Aerospace Systems.

Service costs for the six months ended June 30, 2017 decreased $57 million, or 1 percent, as compared with the same period in 2016, consistent with the change in service sales above.

BACKLOG

Total backlog includes 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 the option or IDIQ task order is exercised or awarded. For multi-year service contracts with non-U.S. Government customers having no stated contract values, backlog includes only the amounts committed by the customer. Backlog is converted into sales as costs are incurred or deliveries are made.

During the six months ended June 30, 2017, the company’s total backlog declined modestly.

OTHER

On July 18, 2017, the Armed Services Board of Contract Appeals made public its decision that the government improperly required Northrop Grumman to treat $253 million of its post-retirement benefit costs as unallowable for government contract cost accounting purposes. The decision, if upheld on any potential appeal, would only apply to certain contracts spanning a 20-year period.

LIQUIDITY AND CAPITAL RESOURCES

We endeavor to ensure the most efficient conversion of operating income into cash for deployment in our business and to maximize 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 free cash flow, a non-GAAP measure described in more detail below.

Cash and cash equivalents and cash generated from operating activities, supplemented by borrowings under credit facilities and/or in the capital markets, if needed, are expected to be sufficient to fund our operations for at least the next 12 months.

NORTHROP GRUMMAN CORPORATION

Operating Cash Flow

The table below summarizes key components of cash flow provided by operating activities:



	Six Months Ended June 30
$ in millions	2017			2016
Net earnings	$	1,192		$	1,073
Non-cash items⁽¹⁾	206			157
Changes in assets and liabilities:
Trade working capital	(1,449		)	(872		)
Retiree benefits	165			209
Other, net	(46		)	(23		)
Net cash provided by operating activities	$	68		$	544


⁽¹⁾	Includes depreciation and amortization, stock based compensation expense and deferred income taxes.

Net cash provided by operating activities for the six months ended June 30, 2017 decreased $476 million, as compared with the same period in 2016. Higher earnings were more than offset by an increase in trade working capital principally due to an increase in accounts receivable and a decrease in accounts payable and other liabilities.

Free Cash Flow

Free cash flow, as reconciled in the table below, is a non-GAAP measure defined as net cash provided 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, stock repurchases, and the payment of dividends. This 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 U.S. GAAP.

The table below reconciles cash provided by operating activities to free cash flow:



	Six Months Ended June 30
$ in millions	2017			2016
Net cash provided by operating activities	$	68		$	544
Less: capital expenditures	(433		)	(471		)
Free cash flow	$	(365	)	$	73

Free cash flow for the six months ended June 30, 2017 decreased $438 million, as compared with the same period in 2016, principally due to the decrease in net cash provided by operating activities described above.

Investing Cash Flow

Net cash used in investing activities for the six months ended June 30, 2017 decreased to $426 million from $469 million in the prior year period principally due to lower capital expenditures.

Financing Cash Flow

Net cash used in financing activities for the six months ended June 30, 2017 decreased to $800 million from $1.3 billion in the prior year period primarily due to lower share repurchases during 2017 and a debt repayment of $107 million in the first quarter of 2016.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

We have provided information about certain legal proceedings in which we are involved in our 2016 Annual Report on Form 10-K, and updated that information in Note 6 to the unaudited condensed consolidated financial statements.

We are a party to various investigations, lawsuits, claims 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 fines; penalties; compensatory, treble or other damages; or non-monetary relief. Government regulations also 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. Suspension or debarment could have a material adverse effect on the company because of our reliance on government contracts and authorizations. The nature of legal proceedings is such that we cannot assure the outcome of any particular matter. However, based on information available to us to date and other than as noted in our 2016 Annual Report on Form 10-K, as updated by Note 6 to the unaudited condensed consolidated financial statements in this report, we do not believe that the outcome of any matter currently pending against the company is likely to have a material adverse effect on the company’s unaudited condensed consolidated financial position as of June 30, 2017, its annual results of operations and/or cash flows. For further information on the risks we face from existing and future investigations, lawsuits, claims and other legal proceedings, please see “Risk Factors” in our 2016 Annual Report on Form 10-K.
