NORTHROP GRUMMAN CORP /DE/ | 2013 | FY | 3


SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Nature of Operations
Northrop Grumman Corporation (herein referred to as “Northrop Grumman,” the “company,” “we,” “us,” or “our”) is a leading global security company providing innovative systems, products and solutions in unmanned systems, cybersecurity, C4ISR, and logistics and modernization to government and commercial customers worldwide through four segments: Aerospace Systems, Electronic Systems, Information Systems and Technical Services. We participate in many high-priority defense and government services programs in the United States (U.S.) and abroad as a prime contractor, principal subcontractor, partner, or preferred supplier. We conduct the majority 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 domestic and international commercial customers.
Principles of Consolidation
The consolidated financial statements include the accounts of Northrop Grumman and its subsidiaries. All 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.
Accounting Estimates
The company’s 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 revenues 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.
Related Party Transactions
For all periods presented, the company had no material related party transactions.
Revenue Recognition
The majority of our business results are derived from long-term contracts with the 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. Generally, sales under cost-reimbursement contracts and construction-type contracts that provide for deliveries at lower volume rates per year or a small number of units are accounted for using the cost-to-cost method. Under this method, sales, including estimated profits, are recorded as costs are incurred. Generally, sales under contracts that provide for deliveries at higher volume rates per year or a large number of units are accounted for using the units-of-delivery method. Under this method, sales are recognized as units are delivered to the customer. The company estimates profit on contracts as the difference between total estimated revenue and total estimated cost of a contract 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 revenue as product or service depending upon the predominant attributes of the contract.
Contract revenues may include estimated amounts not contractually agreed to by the customer, including price redetermination, cost or performance incentives (such as award and incentive fees), un-priced change orders, claims, and requests for equitable adjustment. Amounts pertaining to provisions for price redetermination or for cost and/or performance incentives are included in sales when they are reasonably estimable. 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 are included in revenue when they are probable of recovery in an amount at least equal to the cost. Amounts representing claims (including change orders unapproved as to both scope and price) and requests for equitable adjustment are included in estimated contract revenue only when they are reliably estimable and realization is probable. As of December 31, 2013, the recognized amounts related to claims and requests for equitable adjustment are not material individually or in the aggregate.
The company's U.S. Government contracts generally contain provisions that enable the customer to terminate a contract for default, or for the convenience of the government. If a contract is terminated for default, the contractor may not be entitled to recover any of its costs on partially completed work and may be liable to the government for re-procurement costs of acquiring similar products or services from another contractor, and for certain other damages. Termination of a contract for the convenience of the government may occur when the government concludes it is in the best interests of the government that the contract be terminated. Under a termination for convenience, the contractor is typically entitled to be paid in accordance with the contract’s terms for costs incurred prior to the effective date of termination, plus a reasonable profit and settlement expenses. At December 31, 2013, the company does not have any contract terminations in process that would have a material effect on our consolidated financial position, annual results of operations and/or cash flows.
Changes in estimates of contract sales, costs, or profits are recognized 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. Revenue and profit on future periods of contract performance are recognized as if the revised estimate 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 identifiable. Loss provisions are first offset against costs that are included in unbilled accounts receivable or inventoried costs, and any remaining amount is reflected in liabilities.
Changes in contract estimates occur for a variety of reasons, including changes in contract scope, estimated revenue and cost estimates. These changes are often driven by events such as changes in estimated incentive fees, unanticipated risks affecting contract costs, the resolution of risk at lower or higher cost than anticipated, and changes in indirect cost allocations, such as overhead and general and administrative expenses. We employ an extensive contract management process involving several functional organizations and numerous personnel who are skilled at managing contract activities. Changes in estimates are frequent; the company performs on a broad portfolio of long-term contracts, many of which include complex and customized aerospace and electronic equipment and software, that often include technology at the forefront of science.
Significant changes in estimates on a single contract could have a material effect on the company's consolidated financial position or annual results of operations, and where such changes occur, separate disclosure is made of the nature, underlying conditions and financial impact of the change. Aggregate net changes in contract estimates recognized using the cumulative catch-up method of accounting increased operating income by $753 million ($2.09 per diluted share) in 2013, $985 million ($2.53 per diluted share) in 2012 and $738 million ($1.70 per diluted share) in 2011. No discrete event or adjustments to an individual contract were material to the consolidated statements of earnings and comprehensive income for any of these periods.
General and Administrative Expenses
In accordance with industry practice and regulations that govern the cost accounting requirements for government contracts, most general and administrative expenses incurred at both the segment and corporate locations are considered allowable and allocable costs on government contracts. These costs are allocated to contracts in progress on a systematic basis and are included as a component of total contract costs, including any provision for loss contracts.
Research and Development
Company-sponsored research and development activities primarily include independent research and development (IR&D) efforts related to government programs. Company-sponsored IR&D expenses are included in general and administrative expenses in the consolidated statements of earnings and comprehensive income and are generally allocated to government contracts. Company-sponsored IR&D expenses totaled $507 million, $520 million and $543 million, in 2013, 2012 and 2011, respectively. Expenses for research and development funded by the customer are charged directly to the related contracts.
Environmental Costs
Environmental liabilities are accrued when the company determines that, based on the facts and circumstances known to the company, such amounts are reasonably estimable and it is probable a liability will be found to have been incurred. When only a range of amounts is established and no amount within the range is more probable than another, the low end of the range is recorded. The company typically projects environmental costs for up to 30 years and records environmental liabilities on an undiscounted basis, and does not include legal costs or asset retirement obligations. At sites involving multiple parties, the company accrues environmental liabilities based upon our expected share of liability, taking into account the financial viability of other jointly liable parties. Environmental expenditures are capitalized or expensed, as appropriate. As a portion of environmental remediation costs is expected to be recoverable through overhead charges on government contracts, such amounts are deferred in inventoried costs (current portion) and other non-current assets. Certain capitalized expenditures relate to long-lived improvements in currently operating facilities. The portion of environmental expenditures not expected to be recoverable is expensed. The company does not record insurance recoveries before collection is probable. At December 31, 2013 and 2012, the company did not have any accrued receivables related to insurance reimbursements.
Fair Value of Financial Instruments
The company utilizes fair value measurement guidance prescribed by GAAP to value its financial instruments. The guidance includes a definition of fair value, prescribes methods for measuring fair value, establishes a fair value hierarchy based on the inputs used to measure fair value and expands disclosures about the use of fair value measurements.
The valuation techniques utilized are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect internal market assumptions.
These two types of inputs create the following fair value hierarchy:
Level 1 - Quoted prices for identical instruments in active markets.
Level 2 - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.
Level 3 - Significant inputs to the valuation model are unobservable.
Marketable securities accounted for as trading and available-for-sale are recorded at fair value. For available-for-sale securities, any changes in unrealized gains and losses are reported as a component of other comprehensive income. Changes in unrealized gains and losses on trading securities are included in other, net in the consolidated statements of earnings and comprehensive income. In addition, investments in held-to-maturity instruments with original maturities greater than three months are recorded at amortized cost.
Derivative financial instruments are recognized as assets or liabilities in the financial statements and measured at fair value. Changes in the fair value of derivative financial instruments that qualify and are designated as fair value hedges are recorded in earnings from continuing operations, while the effective portion of the changes in the fair value of derivative financial instruments that qualify and are designated as cash flow hedges are recorded as a component of other comprehensive income. The company may use derivative financial instruments to manage its exposure to interest rate and foreign currency exchange risks and to balance its fixed and variable rate long-term debt portfolio. The company does not use derivative financial instruments for trading or speculative purposes, nor does it use leveraged financial instruments. Credit risk related to derivative financial instruments is considered minimal and is managed by requiring high credit standards for counterparties and through periodic settlements of positions. For derivative financial instruments not designated as cash flow hedging instruments, gains or losses resulting from changes in the fair value are reported in other, net in the consolidated statements of earnings and comprehensive income.
Income Taxes
Provisions for federal and foreign income taxes are calculated on reported financial statement pre-tax income based on current tax law and include the cumulative effect of any changes in tax rates from those used previously in determining deferred tax assets and liabilities. Such provisions differ from the amounts currently payable because certain items of income and expense are recognized in different periods for financial reporting purposes than for income tax purposes. The company recognizes federal interest accrued related to unrecognized tax benefits in income tax expense. Federal penalties are recognized as a component of income tax expense. In accordance with industry practice and regulations that govern the cost accounting requirements for government contracts, state and local income and franchise taxes are considered allowable and allocable costs on government contracts and are therefore recorded in operating costs and expenses. The company recognizes state interest accrued related to unrecognized tax benefits in unallowable operating costs and expenses.
Uncertain tax position represents the company’s expected treatment of a tax position taken in a filed tax return, or planned to be taken in a future tax return or claim, that has not been reflected in measuring income tax expense for financial reporting purposes. Until these positions are sustained by the taxing authorities or the statute of limitations concerning such issues lapses, the company does not recognize the tax benefits resulting from such positions and reports the tax effects as a liability for uncertain tax positions in its consolidated statements of financial position.
Cash and Cash Equivalents
Cash and cash equivalents are comprised of cash in banks and highly liquid instruments with original maturities of three months or less, primarily consisting of bank time deposits and investments in institutional money market funds. The company does not invest in high yield or high risk securities. Cash in bank accounts at times may exceed federally insured limits.
Accounts Receivable and Inventoried Costs
Accounts receivable include amounts billed and currently due from customers, as well as amounts currently due but unbilled (primarily related to costs incurred on contracts accounted for under the cost-to-cost method of percentage-of-completion accounting). Accounts receivable also include certain estimated contract change amounts, claims or requests for equitable adjustment in negotiation that are probable of recovery and amounts retained by the customer pending contract completion.
Accumulated contract costs in unbilled accounts receivable and inventoried costs include direct production costs, factory and engineering overhead, production tooling costs, and, for government contracts, allowable general and administrative expenses. According to the provisions of U.S. Government contracts, the customer asserts title to, or a security interest in, inventories related to such contracts as a result of contract advances, performance-based payments, and progress payments. In accordance with industry practice, unbilled accounts receivable and inventoried costs are classified as current assets and include amounts related to contracts having production cycles longer than one year. Payments received in excess of inventoried costs and unbilled accounts receivable amounts on a contract by contract basis are recorded as advance payments and amounts in excess of costs incurred in the consolidated statements of financial position.
Inventoried costs primarily relate to work in process on contracts accounted for under the units-of-delivery method of percentage-of-completion accounting. These costs represent accumulated contract costs less the portion of such costs allocated to delivered items. Product inventory primarily consists of raw materials and is stated at the lower of cost or market, generally using the average cost method.
Property, Plant and Equipment
Property, plant and equipment are depreciated over the estimated useful lives of individual assets. Most of these assets are depreciated using declining-balance methods, with the remainder using the straight-line method. Major classes of property, plant and equipment and their useful lives are as follows:

Land is not a depreciable asset. Leasehold improvements are depreciated over the useful life of the asset if it is shorter than the length of the lease.
Leases
The company uses its incremental borrowing rate in the assessment of lease classification as capital or operating and defines the initial lease term to include renewal options determined to be reasonably assured. The majority of our leases are operating leases.
Many of the company’s real property lease agreements contain incentives for tenant improvements, rent holidays, or rent escalation clauses. For tenant improvement incentives, the company records a deferred rent liability and amortizes the deferred rent over the term of the lease as a reduction to rent expense. For rent holidays and rent escalation clauses during the lease term, the company records rental expenses on a straight-line basis over the term of the lease. For purposes of recognizing lease incentives, the company uses the date of initial possession as the commencement date, which is generally when the company is given the right of access to the space and begins to make improvements in preparation of intended use.
Goodwill and Other Purchased Intangible Assets
The company performs impairment tests for goodwill annually or when the company believes a potential impairment exists. When it is determined that impairment has occurred, a charge to operations is recorded. Goodwill and other purchased intangible asset balances are included in the identifiable assets of the business segment to which they have been assigned. Purchased intangible assets are generally amortized on a straight-line basis over their estimated useful lives. In the fourth quarter of 2013, the company changed the date of its annual goodwill impairment test from November 30 to December 31. This change in accounting principle is preferable as it aligns the timing of our annual goodwill impairment test with our year-end financial reporting process. This change did not result in the acceleration, delay or avoidance of an impairment charge. The company applied the change in the annual impairment date retrospectively to January 1, 2011; it is impracticable to objectively determine valuation estimates necessary to apply the change in periods prior to that date. There were no changes in previously reported amounts as a result of retrospectively applying the change in the annual impairment testing date. As a result of this change, during 2013, we performed an annual goodwill impairment test as of November 30 and as of December 31.
Cash Surrender Value of Life Insurance Policies
The company maintains whole life insurance policies on a group of executives, which are recorded at their cash surrender value as determined by the insurance carrier. The company also has split-dollar life insurance policies on former officers and executives from acquired businesses, which are recorded at the lesser of their cash surrender value or premiums paid. These policies are utilized as a partial funding source for deferred compensation and other non-qualified employee retirement plans. As of December 31, 2013 and 2012, the carrying values associated with these policies are $287 million and $271 million, respectively, and are recorded in other non-current assets in the consolidated statements of financial position.
Litigation, Commitments and Contingencies
Amounts associated with litigation, commitments, and contingencies are recorded as charges to earnings when management, after taking into consideration the facts and circumstances of each matter as then known to management, including any settlement offers, has determined it is probable a liability will be found to have been incurred and the amount of the loss can be reasonably estimated. When only a range of amounts is established and no amount within the range is more likely than another, the low end of the range is recorded. Legal fees are expensed as incurred.
Retirement Benefits
The company sponsors various pension plans covering substantially all employees. The company also provides post-retirement benefit plans other than pensions, consisting principally of health care and life insurance benefits, to eligible retirees and qualifying dependents. The liabilities, unamortized benefit plan costs and annual income or expense of the company’s pension and other post-retirement benefit plans are determined using methodologies that involve several actuarial assumptions, the most significant of which are the discount rate, the expected long-term rate of return on plan assets, and the cash balance crediting rate. Unamortized benefit plan costs consist primarily of accumulated net after-tax actuarial losses.
Because U.S. Government regulations require that the costs of pension and other post-retirement plans be charged to our contracts with customers in accordance with the Federal Acquisition Regulation and the related CAS (U.S. Government Cost Accounting Standards) that govern such plans, we calculate retiree benefit plan costs under both CAS and FAS (GAAP Financial Accounting Standards) methods. While both FAS and CAS recognize a normal service cost component in measuring periodic pension cost, there are differences in the way the remaining components of annual pension costs are calculated under each method. Measuring plan obligations under FAS and CAS methods utilize different assumptions and models, such as in estimating earnings on plan assets and calculating interest expense. In addition, the periods over which gains/losses related to pension assets and actuarial changes are amortized are different under each FAS/CAS method. As a result, annual retiree benefit plan expense amounts for FAS are different from the amounts for CAS even though the ultimate cost of providing benefits is the same under either method. CAS retiree benefit plan costs are charged to contracts and are included in segment operating income, and the difference between CAS and FAS expense is recorded in operating income at the consolidated company level.
Net actuarial gains or losses are amortized to expense on a plan-by-plan basis when they exceed the accounting corridor. The accounting corridor is a defined range within which amortization of net gains and losses is not required and is equal to 10 percent of the greater of the plan assets or benefit obligations. Gains or losses outside of the corridor are subject to amortization over our average employee future service period of approximately nine years. The fair values of plan assets are determined based on prevailing market prices or estimated fair value for investments with no available quoted prices. Not all net periodic pension expense is recognized in net earnings in the year incurred because it is allocated as production costs and a portion remains in inventory at the end of a reporting period. The company’s funding policy for the qualified pension plans is to contribute, at a minimum, the statutorily required amount to an irrevocable trust.
Stock Compensation
The company’s stock compensation plans are classified as equity plans and compensation expense is recognized over the vesting period (generally three years), net of estimated forfeitures. The company issues stock awards in the form of restricted performance stock rights and restricted stock rights under its existing plans. The fair value of stock awards is determined based on the closing market price of the company’s common stock on the grant date. At each reporting date, the number of shares is adjusted to equal the number ultimately expected to vest.
Foreign Currency Translation
For operations outside the U.S. that have functional currencies other than the U.S. dollar, results of operations and cash flows are translated at average exchange rates during the period, and assets and liabilities are translated at end-of-period exchange rates. Translation adjustments are generally included as a component of other comprehensive income in the consolidated statements of earnings and comprehensive income.
Accounting Standards Updates
Accounting standards updates effective after December 31, 2013, are not expected to have a material effect on the company’s financial position, annual results of operations and/or cash flows.
Accumulated Other Comprehensive Loss
The components of accumulated other comprehensive loss are as follows:

Unamortized benefit plan costs consist primarily of net after-tax actuarial losses totaling $3.3 billion and $5.1 billion as of December 31, 2013 and 2012, respectively. Net actuarial gains or losses are re-determined annually and principally arise from changes in the rate used to discount our benefit obligations, as well as differences in expected and actual returns on plan assets.
Reclassifications from other comprehensive income to net earnings related to the amortization of benefit plan costs were losses of $319 million, $204 million and $91 million, net of taxes, for the years ended December 31, 2013, 2012 and 2011, 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 13 for further information).
Reclassifications from other comprehensive income to net earnings, relating to cumulative translation adjustments, marketable securities and effective cash flow hedges for the years ended December 31, 2013, 2012 and 2011, 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.
