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, 2014 (2014 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

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 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.

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; 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 changes in estimates on a single contract could have a material effect on the company's unaudited condensed consolidated financial position or results of operations. Where such changes occur, we generally disclose the nature, underlying conditions and financial impact of the change. No discrete event or adjustments to an individual contract were material to the accompanying unaudited condensed consolidated financial statements.

The effect of aggregate net changes in contract estimates recognized using the cumulative catch-up method of accounting is as follows:



	Three Months Ended September 30				Nine Months Ended September 30
$ in millions, except per share data	2015		2014		2015		2014
Operating Income	$	112	$	194	$	461	$	556
Net Earnings ⁽¹⁾	73		126		300		361
Diluted earnings per share ⁽¹⁾	0.39		0.60		1.55		1.68

(1) Based on statutory tax rates

As of September 30, 2015, the recognized amounts related to contract claims and requests for equitable adjustment are not material individually or in aggregate. In addition, as of September 30, 2015, the company does not have any contract terminations in process that we anticipate would 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 May 28, 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers. ASU 2014-09 supersedes existing revenue recognition guidance, including Accounting Standards Codification (ASC) No. 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 are currently evaluating 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.

Other accounting standards updates effective after September 30, 2015, 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.

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	September 30, 2015			December 31, 2014
Unamortized benefit plan costs, net of tax benefit of $3,217 as of September 30, 2015 and $3,395 as of December 31, 2014	$	(5,028	)	$	(5,316	)
Cumulative translation adjustment	(72		)	(41		)
Net unrealized gain on marketable securities and cash flow hedges, net of tax	1			1
Total accumulated other comprehensive loss	$	(5,099	)	$	(5,356	)

Unamortized benefit plan costs consist primarily of net after-tax actuarial losses totaling $5.3 billion and $5.6 billion as of September 30, 2015 and December 31, 2014, 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 $96 million and $288 million, net of taxes, for the three and nine months ended September 30, 2015, respectively, and were $35 million and $108 million, net of taxes, for the three and nine months ended September 30, 2014, 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 nine months ended September 30, 2015 and 2014, respectively, were not material. Reclassifications for cumulative translation adjustments and marketable securities are recorded in other income, and reclassifications for effective cash flow hedges are recorded in operating income.
