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 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.
The accompanying unaudited condensed consolidated financial statements are prepared in accordance with the rules of the Securities and Exchange Commission (SEC) for interim reporting purposes. 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, 2015 (2015 Annual Report on Form 10-K) and the Form 8-K that we filed with the SEC on April 27, 2016, which recasts the disclosures in certain portions of the 2015 Annual Report on Form 10-K to reflect changes in the company’s organizational structure and reportable segments.
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
The accompanying unaudited condensed consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). 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 United States (U.S.) Government for the production of goods, the provision of services, or in some cases, 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.
Net Estimate-At-Completion (EAC) Adjustments - We recognize changes in estimated contract sales, costs or profits using the cumulative catch-up method of accounting. This method recognizes, in the current period, the cumulative effect of the changes on current and prior periods as net EAC adjustments; sales and profit 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 is charged against income in the period the loss is identified. Loss provisions are first offset against any costs that are included in unbilled accounts receivable or inventoried costs, and any remaining amount is reflected in 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.

Based on statutory tax rates
Contract sales may include estimated amounts not contractually agreed to 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. During July 2016, the company entered into a contract modification with the U.S. government on an Aerospace Systems program, which resolved most of the REAs disclosed in our 2015 Annual Report on Form 10-K. Amounts recognized related to claims and REAs as of June 30, 2016 were not material individually or in aggregate.
As of June 30, 2016, the company does not have any contract terminations in process that we anticipate will have a material effect on our unaudited condensed consolidated financial position, or our annual results of operations and/or cash flows.
Related Party Transactions
For all periods presented, the company had no material related party transactions.
Accounting Standards Updates
On March 30, 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The company adopted ASU 2016-09 during the first quarter of 2016. Among other things, the ASU requires that entities recognize excess tax benefits and deficiencies related to employee share-based payment transactions as income tax expense or benefit. The ASU also eliminates the requirement to reclassify excess tax benefits and deficiencies from operating activities to financing activities in the statement of cash flows. As a result of adoption, the company recognized a $4 million and $84 million tax benefit during the three and six months ended June 30, 2016, respectively. Adoption also resulted in an $84 million increase in operating cash flows and a corresponding $84 million reduction in financing cash flows for the six months ended June 30, 2016.
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, the new standard requires recognition of a right-of-use asset and liability for future lease payments for contracts that meet the definition of a lease. ASU 2016-02 will be effective January 1, 2019, although early adoption is permitted. The standard must be applied using a modified retrospective approach. We are currently evaluating the timing of adoption as well as the effect ASU 2016-02 will have on the company’s consolidated financial position, annual results of operations and 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. ASU 2014-09 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. These concepts, as well as other aspects of ASU 2014-09, may change the method and/or timing of revenue recognition for certain of our contracts. 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 complete our evaluation of both methods of adoption as well as the effect ASU 2014-09 will have on the company’s consolidated financial position, annual results of operations and cash flows by the end of 2016.

NORTHROP GRUMMAN CORPORATION                        

Other accounting standards updates effective after June 30, 2016 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.
Reclassifications
The company adopted ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, during the first quarter of 2016. As a result, we now present capitalized debt issuance costs as a reduction in the carrying amount of long-term debt. This change resulted in a reclassification of $30 million of other non-current assets reported in our 2015 consolidated statement of financial position to long-term debt, which reduced our previously reported total assets and total liabilities as of December 31, 2015.
Shareholders’ Equity
The company records the difference between the cost of shares repurchased and their par value as well as tax withholding in excess of related stock compensation expense as a reduction of paid-in capital to the extent available and then as a reduction of retained earnings.
Accumulated Other Comprehensive Loss
The components of accumulated other comprehensive loss are as follows:
$ in millions

2016
 
December 31,

Unamortized benefit plan costs, net of tax benefit of $3,227 as of June 30, 2016 and $3,350 as of December 31, 2015

Total accumulated other comprehensive loss
$
(5,132
)
 
$
(5,320
)
Unamortized benefit plan costs consist primarily of net after-tax actuarial losses totaling $5.2 billion and $5.5 billion as of June 30, 2016 and December 31, 2015, 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 $201 million, net of taxes, for the three and six months ended June 30, 2016, respectively, and were $96 million and $192 million, net of taxes, for the three and six months ended June 30, 2015, respectively. The reclassifications represent the amortization of net actuarial losses and prior service credits for the company’s retirement benefit plans, 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 for the three and six months ended June 30, 2016 and 2015, respectively, were not material.
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 includes the dilutive effect of awards granted to employees under stock-based compensation plans. The dilutive effect of these securities totaled 1.4 million shares and 1.7 million shares for the three and six months ended June 30, 2016, respectively. The dilutive effect of these securities totaled 1.9 million shares and 2.3 million shares for the three and six months ended June 30, 2015, respectively.
Share Repurchases
On May 15, 2013, the company’s board of directors authorized a share repurchase program of up to $4.0 billion of the company’s common stock (2013 Repurchase Program). Repurchases under the 2013 Repurchase Program commenced in September 2013 and were completed in March 2015. On December 4, 2014, the company’s board of directors authorized a new share repurchase program of up to $3.0 billion of the company’s common stock (2014 Repurchase Program). Repurchases under the 2014 Repurchase Program commenced in March 2015 and were completed in March 2016.

NORTHROP GRUMMAN CORPORATION                        

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 (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, 2016, repurchases under the 2015 Repurchase Program totaled $0.4 billion; $3.6 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:

3.    SEGMENT INFORMATION
The company is aligned in three operating sectors, which also comprise our reportable segments: Aerospace Systems, Mission Systems and Technology Services. Effective January 1, 2016, the company streamlined our sectors from four to three to better align our business with the evolving needs of our customers and enhance innovation across the company. Mission Systems and Technology Services were created by merging elements of our former Electronic Systems, Information Systems and Technical Services sectors. The new Mission Systems sector is composed of the majority of our former Electronic Systems sector and the businesses from our former Information Systems sector focused on the development of new capabilities for our military and intelligence customers. The new Technology Services sector was formed by combining the services portfolio in the former Information Systems sector with the former Technical Services sector. Among other operations that were realigned, the military and civil space hardware business in Azusa, California, previously reporting to the Electronic Systems sector, moved to the Aerospace Systems sector, and the electronic attack business, previously in the Aerospace Systems sector, moved to the Mission Systems sector.

Net FAS/CAS Pension Adjustment
For financial statement purposes, we account for our employee pension plans in accordance with GAAP under FAS (GAAP Financial Accounting Standards). 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) that govern such plans. The net FAS/CAS pension adjustment reflects the difference between CAS pension expense included as cost in segment operating income and FAS expense determined in accordance with GAAP.
The decrease in net FAS/CAS pension adjustment for the three and six months ended June 30, 2016, as compared to the same periods in 2015, is primarily due to lower than expected asset returns during 2015, partially offset by the increase in our FAS discount rate assumption as of December 31, 2015 and the continued phase-in of the effects of CAS harmonization.
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 costs, retiree benefits and corporate unallowable costs.
Current Quarter
Unallocated corporate expenses for the three months ended June 30, 2016 were comparable with the same period in 2015 and both periods reflect a reduction in reserves for overhead costs related to the finalization of certain prior year incurred cost claims.
Year to Date
Unallocated corporate expenses decreased for the six months ended June 30, 2016, as compared with the same period in 2015, principally due to higher deferred state taxes in 2015 resulting from a $500 million discretionary pension contribution made in the first quarter of 2015.

Current Quarter
The company’s effective tax rate for the three months ended June 30, 2016 was higher than the comparable 2015 period primarily due to the absence of $38 million of refund claims filed in 2015, partially offset by extension of the research tax credit.
Year to Date
The company’s effective tax rate for the six months ended June 30, 2016 was lower than the comparable 2015 period principally due to $84 million of excess tax benefits related to employee share-based payment transactions recognized in 2016 resulting from the adoption of ASU No. 2016-09 described in Note 1 and extension of the research tax credit, partially offset by the absence of $38 million of refund claims filed in 2015.
We file income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. As of June 30, 2016, our 2007-2013 federal tax returns were either under Internal Revenue Service (IRS) examination or on appeal. During July 2016, the U.S. Congressional Joint Committee on Taxation approved a resolution of the IRS examination of the company’s 2007-2011 tax returns. As a result, in the third quarter of 2016, the company will record a reduction of our unrecognized tax benefits of approximately $115 million and a reduction of our income tax expense of approximately $40 million. The company believes it is reasonably possible that within the next twelve months we may resolve additional tax matters, which may result in further reductions of our unrecognized tax benefits up to $70 million and income tax expense up to $45 million.

There were no transfers of financial instruments between the three levels of the fair value hierarchy during the six months ended June 30, 2016.
The carrying value of cash and cash equivalents approximates fair value.
Investments in Marketable Securities
The company holds a portfolio of marketable securities consisting of securities to partially fund non-qualified employee benefit plans. These assets are recorded at fair value on a recurring basis and substantially all of these instruments are valued using Level 1 inputs. As of June 30, 2016 and December 31, 2015, marketable securities of $313 million and $310 million, respectively, were included in other non-current assets in the unaudited condensed consolidated statements of financial position.
Derivative Financial Instruments and Hedging Activities
The company’s derivative portfolio consists primarily of foreign currency forward contracts. The notional value of the company’s derivative portfolio at June 30, 2016 and December 31, 2015, was $127 million and $141 million, respectively. The portion of the notional value designated as cash flow hedges at June 30, 2016 and December 31,

-10-
Table of Contents

NORTHROP GRUMMAN CORPORATION                        

2015, was $4 million and $10 million, respectively. Substantially all of these instruments are valued using Level 2 inputs. 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 June 30, 2016 and December 31, 2015, were not material.
Long-term Debt
The fair value of long-term debt is calculated using Level 2 inputs based on interest rates available for debt with terms and maturities similar to the company’s existing debt arrangements.
Unsecured Senior Notes
In February 2015, the company issued $600 million of unsecured senior notes due April 15, 2045 with a fixed interest rate of 3.85 percent. We used the net proceeds from this offering for general corporate purposes, including the funding of a $500 million voluntary contribution to our pension plans in the first quarter of 2015 and most of a debt repayment of $107 million in the first quarter of 2016.
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 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 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, 2016), 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, 2016) 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, 2016). 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 million as of June 30, 2016), 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

-11-
Table of Contents

NORTHROP GRUMMAN CORPORATION                        

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 one of several defendants in litigation brought by the Orange County Water District in Orange County Superior Court in California on December 17, 2004, for alleged contribution to volatile organic chemical contamination of the County’s shallow groundwater. The lawsuit includes counts against the defendants for violation of the Orange County Water District Act, the California Super Fund Act, negligence, nuisance, trespass and declaratory relief. Among other things, the lawsuit seeks unspecified damages for the cost of remediation, payment of attorney fees and costs, and punitive damages. Trial on the statutory claims (those based on the Orange County Water District Act, the California Super Fund Act and declaratory relief) concluded on September 25, 2012. On October 29, 2013, the court issued its decision in favor of the defendants on the statutory claims. On May 9, 2014, the court granted defendants’ dispositive motions on the remaining tort causes of action. Notice of entry of judgment was filed on July 1, 2014. The Orange County Water District filed a notice of appeal on August 28, 2014. The parties have submitted their briefs to the court.
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, 2016, or its annual results of operations or cash flows.
7.    COMMITMENTS AND CONTINGENCIES
Guarantees of Certain Performance Obligations
The company’s subsidiaries enter into joint ventures, teaming and other business arrangements (collectively, Business Arrangements) to support our products and services in U.S. and international markets. The company generally strives to limit its exposure under these arrangements to its subsidiary’s investment in the Business Arrangements or to the extent of such subsidiary’s obligations under the applicable contract. In some cases, however, the company may be required to guarantee performance by the Business Arrangements and, in such cases, the company generally strives to obtain cross-indemnification from the other members of the Business Arrangements.
At June 30, 2016, the company is not aware of any existing event of default that would require it to satisfy any of these guarantees.
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 estimated exposure for matters raised by the U.S. Government. 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 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, 2016, 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, 2016 and December 31, 2015:

(1) 
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, 2016, $101 million is recorded in other current liabilities and $270 million is recorded in other non-current liabilities.
(3) As of June 30, 2016, $56 million is deferred in inventoried costs and $133 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, 2016, 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, 2016, there were $280 million of stand-by letters of credit and guarantees and $151 million of surety bonds outstanding.
Indemnifications
The company has retained 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, 2016, 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, 2016 was $68 million and $159 million, respectively, and was $76 million and $157 million for the three and six months ended June 30, 2015, respectively. These amounts are net of immaterial amounts of sublease rental income.
Credit Facility
The company maintains an unsecured credit facility in an aggregate principal amount of $1.6 billion (the “Credit Agreement”) that matures in July 2020. At June 30, 2016, the company was in compliance with the covenants under the Credit Agreement and there was no balance outstanding.

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, 2016, and the related condensed consolidated statements of earnings and comprehensive income for the three-month and six-month periods ended June 30, 2016 and 2015, and of cash flows and changes in shareholders’ equity for the six-month periods ended June 30, 2016 and 2015. 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, 2015, and the related consolidated statements of earnings and comprehensive income (loss), cash flows, and changes in shareholders’ equity for the year then ended (not presented herein); and in our report dated February 1, 2016 (April 26, 2016 as to the reclassification of segment information), 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, 2015, is fairly stated, in all material respects, in relation to the consolidated statement of financial position from which it has been derived.

We also conduct business with foreign, state and local governments and 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 2015 Annual Report on Form 10-K and the Form 8-K that we filed with the SEC on April 27, 2016, which recasts the disclosures in certain portions of the 2015 Annual Report on Form 10-K to reflect changes in the company’s organizational structure and reportable segments. See further discussions in the Consolidated Operating Results and Segment Operating Results sections that follow.
Political and Economic Environment
The following is an update of events relating to the company’s political and economic environment since the filing of our 2015 Annual Report on Form 10-K.
On February 9, 2016, the President delivered his FY 2017 budget to Congress. The FY 2017 budget reflects the FY 2017 spending caps established in the Bipartisan Budget Act of 2015 and requests $524 billion for the DoD’s annual budget and an additional $59 billion for Overseas Contingency Operations. Congress is continuing to consider appropriations bills for FY 2017. It is unclear when or if annual appropriations bills will be enacted for FY 2017. The U.S. Government may operate under a continuing resolution for some or all of FY 2017, restricting new contract or program starts for that year and placing limitations on some planned program budgets, and we may face a government shutdown of unknown duration.
Operating Performance Assessment and Reporting
We manage and assess our business based on our performance on contracts and programs (typically 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 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 costs, subcontractor costs, material costs, overhead costs 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, including the effects of meaningful changes in operating income as a result of changes in contract estimates. 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 below of results of operations 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, 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.

See Segment Operating Results below for further information by segment and the Product and Service Analysis section that follows Segment Operating Results for product and service detail.
Operating Costs and Expenses
Operating costs and expenses primarily comprise labor, material, subcontractor and overhead costs, and are generally allocated to contracts as incurred. In accordance with industry practice and the regulations that govern cost accounting requirements for government contracts, most general management and corporate expenses incurred at the segment and corporate locations are considered allowable and allocable costs. Allowable and allocable G&A costs, including independent research and development (IR&D) and bid and proposal costs, are allocated on a systematic basis to contracts in progress.

Current Quarter
Operating costs and expenses as a percentage of sales increased for the three months ended June 30, 2016 as compared with the same period in 2015, which decreased our operating margin rate to 13.3 percent from 13.8 percent in the prior year period. The increase in operating costs and expenses as a percentage of sales was principally driven by lower segment margin rates, as described in the Segment Operating Results section below, and a $12 million decrease in our net FAS (GAAP Financial Accounting Standards)/CAS pension adjustment, as described in Note 3 to the unaudited condensed consolidated financial statements in Part I, Item 1.

Table of Contents

NORTHROP GRUMMAN CORPORATION                        

G&A as a percentage of sales for the three months ended June 30, 2016 decreased to 10.3 percent from 10.9 percent in the prior year period, principally due to the timing of indirect costs at Mission Systems.
Year to Date
Operating costs and expenses as a percentage of sales increased for the six months ended June 30, 2016 as compared with the same period in 2015, which decreased our operating margin rate to 12.8 percent from 13.4 percent in the prior year period. The increase in operating costs and expenses as a percentage of sales was principally driven by lower segment margin rates, as described in the Segment Operating Results section below, and a $21 million decrease in our net FAS/CAS pension adjustment, as described in Note 3 to the unaudited condensed consolidated financial statements in Part I, Item 1.
G&A as a percentage of sales for the six months ended June 30, 2016 was comparable with the same period in 2015.
For further information regarding product and service sales and costs, see the Product and Service Analysis section that follows Segment Operating Results.
Operating Income and Margin Rate
We define operating income as sales less operating costs and expenses, which includes G&A. Operating margin rate is defined as operating income as a percentage of sales.
Current Quarter
Operating income for the three months ended June 30, 2016 decreased $16 million, or 2 percent, as compared with the same period in 2015, and operating margin rate decreased to 13.3 percent from 13.8 percent in the prior year period primarily due to the higher operating costs and expenses described above.
Year to Date
Operating income for the six months ended June 30, 2016 decreased $57 million, or 4 percent, as compared with the same period in 2015, and operating margin rate decreased to 12.8 percent from 13.4 percent in the prior year period primarily due to the higher operating costs and expenses described above.
Federal and Foreign Income Taxes
Current Quarter
The company’s effective tax rate for the three months ended June 30, 2016 was 29.2 percent as compared with 27.9 percent in the comparable 2015 period. The higher rate is primarily due to the absence of $38 million of refund claims filed in 2015, partially offset by extension of the research tax credit.
Year to Date
The company’s effective tax rate for the six months ended June 30, 2016 was 23.7 percent as compared with 29.5 percent in the comparable 2015 period. The lower rate is principally due to $84 million of excess tax benefits related to employee share-based payment transactions recognized in 2016 due to the adoption of Accounting Standards Update (ASU) No. 2016-09, as described in Note 1 to the unaudited condensed consolidated financial statements in Part I, Item 1, and extension of the research tax credit, partially offset by the absence of $38 million of refund claims filed in 2015.
Net Earnings
Current Quarter
Net earnings for the three months ended June 30, 2016 decreased $14 million, or 3 percent, as compared with the same period in 2015, principally due to lower operating income, as described above, partially offset by an increase in Other, net as a result of higher returns on marketable securities.
Year to Date
Net earnings for the six months ended June 30, 2016 increased $58 million, or 6 percent, as compared with the same period in 2015, principally due to the lower effective tax rate discussed above and an increase in Other, net as a result of higher returns on marketable securities, partially offset by the lower operating income discussed above.
Diluted Earnings Per Share
Current Quarter
Diluted earnings per share for the three months ended June 30, 2016 increased $0.11, or 4 percent, as compared with the same period in 2015, reflecting lower weighted-average shares outstanding resulting from shares repurchased during 2015 and 2016, partially offset by lower net earnings.

Current Quarter
Aerospace Systems sales for the three months ended June 30, 2016 increased $102 million, or 4 percent, as compared with the same period in 2015. The increase was due to higher volume on Manned Aircraft and Autonomous Systems programs, partially offset by lower volume on Space programs. Manned Aircraft sales increased primarily due to higher restricted volume and increased F-35 deliveries, partially offset by fewer F/A-18 deliveries and lower B-2 volume. Autonomous Systems sales increased primarily due to higher volume on the Global Hawk and Triton programs, partially offset by the ramp-down of the NATO Alliance Ground Surveillance (AGS) program. Space sales declined due to lower volume on the Advanced Extremely High Frequency (AEHF) and James Webb Space Telescope (JWST) programs, partially offset by higher restricted volume.
Operating income for the three months ended June 30, 2016 decreased $7 million, or 2 percent, and operating margin rate decreased to 12.0 percent from 12.8 percent. Operating income and margin rate decreased due to lower margins on Manned Aircraft programs, principally due to changes in contract mix and the timing of risk reductions, which more than offset the higher sales volume described above and improved performance on Space programs.
Year to Date
Aerospace Systems sales for the six months ended June 30, 2016 increased $178 million, or 4 percent, as compared with the same period in 2015. The increase was due to higher volume on Manned Aircraft and Autonomous Systems programs, partially offset by lower volume on Space programs. Manned Aircraft sales increased primarily due to higher restricted volume, increased F-35 deliveries and the transition to full rate production on the E-2D Advanced Hawkeye program. These increases were partially offset by fewer F/A-18 deliveries and lower B-2 volume. Autonomous Systems sales increased primarily due to higher volume on the Global Hawk and Triton programs, partially offset by the ramp-down of the NATO AGS program. Space sales declined due to lower volume on the AEHF and JWST programs, partially offset by higher restricted volume.
Operating income for the six months ended June 30, 2016 decreased $33 million, or 5 percent, and operating margin rate decreased to 11.6 percent from 12.6 percent. Operating income and margin rate decreased due to lower margins on Manned Aircraft programs, principally due to changes in contract mix and the timing of risk reductions, which more than offset the higher sales volume described above and improved performance on Space programs.

Mission Systems sales for the three months ended June 30, 2016 increased $62 million, or 2 percent, as compared with the same period in 2015. The increase was primarily due to higher volume on Advanced Capabilities programs, as well as Sensors and Processing programs. Advanced Capabilities sales increased primarily due to higher restricted volume and ramp-up on a number of navigation and maritime programs, including Surface Electronic Warfare Improvement Program (SEWIP) Block III. Sensors and Processing sales increased primarily due to ramp-up on the G/ATOR and Joint Counter Radio-Controlled Improvised Explosive Device Electronic Warfare (JCREW) programs, partially offset by lower volume on international and combat avionics programs.
Operating income for the three months ended June 30, 2016 increased $3 million, or 1 percent, and operating margin rate decreased to 13.0 percent from 13.2 percent. Operating income increased primarily due to the higher sales

volume described above. Operating margin rate declined principally due to lower margins on Sensors and Processing programs due to changes in contract mix.
Year to Date
Mission Systems sales for the six months ended June 30, 2016 increased $44 million, or 1 percent, as compared with the same period in 2015. The increase was due to higher volume on Advanced Capabilities and Sensors and Processing programs, partially offset by lower volume on Cyber and ISR programs. Advanced Capabilities sales increased primarily due to ramp-up on a number of navigation and maritime programs, including SEWIP Block III, and higher restricted volume. Sensors and Processing sales increased primarily due to production ramp-up on the G/ATOR program and higher volume on fixed wing avionics and C4ISR programs. These increases were partially offset by lower volume on international and combat avionics programs. Cyber and ISR sales reflect lower volume on restricted programs and the Counter Narcoterrorism Technology program.
Operating income for the six months ended June 30, 2016 increased $12 million, or 2 percent, and operating margin rate increased to 13.1 percent from 13.0 percent. Operating income and margin rate increased primarily due to the higher sales volume described above and higher margins on Advanced Capabilities programs due to improved performance, partially offset by lower margins on Sensors and Processing programs due to the timing of risk reductions and changes in contract mix.

Technology Services sales for the three months ended June 30, 2016 decreased $25 million, or 2 percent, as compared with the same period in 2015. The decrease was principally due to lower volume on Advanced Defense Services programs, partially offset by higher volume on Global Logistics and Modernization programs. Advanced Defense Services sales declined primarily due to the completion of several programs in 2015, partially offset by higher volume on the Saudi Arabian Ministry of National Guard Training Support (MNG TSC) program (through our interest in a joint venture for which we consolidate the financial results). Global Logistics and Modernization sales increased mainly due to higher KC-10 volume, partially offset by lower volume on the Intercontinental Ballistic Missile (ICBM) program.
Operating income for the three months ended June 30, 2016 increased $3 million, or 2 percent, and operating margin rate increased to 10.8 percent from 10.3 percent. Operating income and margin rate increased primarily due to improved performance on System Modernization and Services and Global Logistics and Modernization programs, partially offset by lower margins on Advanced Defense Services programs due to the positive impact of EAC adjustments related to the completion of several programs in 2015.
Year to Date
Technology Services sales for the six months ended June 30, 2016 decreased $78 million, or 3 percent, as compared with the same period in 2015. The decrease was principally due to lower volume on Global Logistics and Modernization and Advanced Defense Services programs. Global Logistics and Modernization sales decreased mainly due to lower volume on the ICBM program and restricted programs, partially offset by higher KC-10 volume. Advanced Defense Services sales declined primarily due to the completion of several programs in 2015, partially offset by higher volume on the MNG TSC and Passenger Systems Program Directorate programs.
Operating income for the six months ended June 30, 2016 decreased $4 million, or 2 percent, and operating margin rate increased to 10.6 percent from 10.4 percent. Operating income declined primarily due to the lower sales volume described above. Operating margin rate increased principally due to improved performance on System Modernization and Services and Global Logistics and Modernization programs, partially offset by lower margins on Advanced Defense Services programs due to the positive impact of EAC adjustments related to the completion of several programs in 2015.

The reconciliation of segment operating income to total operating income, as well as a discussion of the reconciling items, is included in Note 3 to the unaudited condensed consolidated financial statements in Part I, Item 1.
Product Sales and Costs
Current Quarter
Product sales for the three months ended June 30, 2016 increased $80 million, or 2 percent, as compared with the same period in 2015. The increase was primarily driven by higher product sales on Manned Aircraft programs at Aerospace Systems due to higher restricted volume and increased F-35 deliveries, partially offset by fewer F/A-18 deliveries.
Product costs for the three months ended June 30, 2016 increased $52 million, or 2 percent, consistent with the change in product sales described above. Higher product margins at Mission Systems and Technology Services were partially offset by lower product margins at Aerospace Systems due to changes in contract mix.
Year to Date
Product sales for the six months ended June 30, 2016 increased $126 million, or 2 percent, as compared with the same period in 2015. The increase was driven primarily by higher product sales at Aerospace Systems, partially offset by lower product sales at Mission Systems. The increase at Aerospace Systems was primarily due to higher volume on Manned Aircraft programs. The decrease at Mission Systems was primarily due to lower volume on international, restricted and combat avionics production programs, partially offset by ramp-up on the G/ATOR program.
Product costs for the six months ended June 30, 2016 increased $123 million, or 2 percent, consistent with the change in product sales described above.
Service Sales and Costs
Current Quarter
Service sales for the three months ended June 30, 2016 increased $59 million, or 2 percent, as compared with the same period in 2015. The increase was primarily due to higher service sales at Mission Systems due to higher volume and ramp-up on several Sensors and Processing service programs.
Service costs for the three months ended June 30, 2016 increased $88 million, or 4 percent, as compared with the same period in 2015. The increase was primarily driven by the increase in service sales described above as well as lower service margins at Mission Systems due to ramp-up on several Sensors and Processing service programs.

Year to Date
Service sales for the six months ended June 30, 2016 increased slightly as compared with the same period in 2015. The increase was primarily due to higher service sales at Mission Systems due to ramp-up on several Sensors and Processing service programs, partially offset by lower service volume on restricted service programs at Aerospace Systems and on the ICBM program at Technology Services.
Service costs for the six months ended June 30, 2016 increased $46 million, or 1 percent, as compared with the same period in 2015. The increase was primarily driven by the increase in service sales described above as well as lower service margins at Aerospace Systems due to the timing of risk reductions.
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, 2016, the company’s total backlog increased and reflects higher backlog at Aerospace Systems, a high single-digit percent decline in backlog at Technology Services and a modest decline in backlog at Mission Systems. The company recorded various awards during the six months ended June 30, 2016, including a portion of the B-21 Long-Range Strike Bomber program.
LIQUIDITY AND CAPITAL RESOURCES
We endeavor to achieve the most efficient conversion of operating income into cash for deployment in our business and to maximize shareholder value through other 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 (used in) operating activities and free cash flow. We believe these measures are useful to investors in assessing our financial performance and condition.
Cash balances and cash generated from operating activities, supplemented by borrowings under credit facilities, if needed, are expected to be sufficient to fund our operations for at least the next 12 months.
Operating Cash Flow
The table below summarizes key components of cash flow provided by (used in) operating activities:

Includes depreciation and amortization, stock based compensation expense (including related excess tax benefits in 2015) and deferred income taxes.
Net cash provided by operating activities for the six months ended June 30, 2016 increased $572 million, as compared with the same period in 2015, principally due to a $500 million voluntary pre-tax pension contribution ($325 million after-tax) made in the first quarter of 2015, changes in trade working capital and the impact of the adoption of ASU No. 2016-09 described in Note 1 to the unaudited condensed consolidated financial statements in Part I, Item 1.
Free Cash Flow
We define free cash flow as cash provided by (used in) operating activities less capital expenditures. We believe free cash flow is a useful measure for investors as it represents cash flow available after capital spending and is a key factor in our planning for, and consideration of, acquisitions, payment of dividends and stock repurchases.

Free cash flow is not a measure of financial performance under GAAP, and may not be defined and calculated by other companies in the same manner. This measure should not be considered in isolation, as a measure of residual cash flow available for discretionary purposes, or as an alternative to operating results presented in accordance with GAAP as indicators of performance.
The table below reconciles cash provided by (used in) operating activities to free cash flow:

(260
)
Free cash flow for the six months ended June 30, 2016 increased $333 million, as compared with the same period in 2015, principally due to the increase in net cash provided by operating activities described above, partially offset by higher capital expenditures in 2016, including $239 million for the purchase of facilities previously leased by Mission Systems.
Investing Cash Flow
Net cash used in investing activities for the six months ended June 30, 2016 increased to $469 million from $234 million in the prior year period principally due to higher capital expenditures, including the $239 million purchase of facilities described above.
Financing Cash Flow
Net cash used in financing activities for the six months ended June 30, 2016 decreased to $1.3 billion from $1.7 billion in the prior year period primarily due to lower share repurchases in 2016, partially offset by $600 million of net proceeds from our issuance of unsecured senior notes in 2015, a debt repayment of $107 million in 2016, and the impact of the adoption of ASU No. 2016-09 described in Note 1 to the unaudited condensed consolidated financial statements in Part I, Item 1.
Unsecured Senior Notes - See Note 5 to the unaudited condensed consolidated financial statements in Part I, Item 1 for further information on our unsecured senior notes.

Forward-looking statements are based upon assumptions, expectations, plans and projections that we believe to be reasonable when made, but which may change over time. These statements are not guarantees of future performance and inherently involve a wide range of risks and uncertainties that are difficult to predict. Specific risks that could cause actual results to differ materially from those expressed or implied in these

DISCLOSURE CONTROLS AND PROCEDURES
Our principal executive officer (Chairman, Chief Executive Officer and President) and principal financial officer (Corporate Vice President and Chief Financial Officer) have evaluated the company’s disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) of the Securities Exchange Act of 1934 (the Exchange Act)) as of June 30, 2016, and have concluded that these controls and procedures are effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms.

PART II. OTHER INFORMATION
Item 1. Legal Proceedings
We have provided information about certain legal proceedings in which we are involved in our 2015 Annual Report on Form 10-K, and updated that information in Note 6 to the unaudited condensed consolidated financial statements in Part I, Item 1.
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. U.S. 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 2015 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, 2016, 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 Part I, Item 1A of our 2015 Annual Report on Form 10-K.
