Basis Of Presentation [Abstract]

Use Of Estimates In Preparation Of Financial Statements

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the amounts of revenues and expenses reported for the period. Actual results could differ from estimates.

Most of our satellite manufacturing revenue is associated with long-term contracts which require significant estimates. These estimates include forecasts of costs and schedules, estimating contract revenue related to contract performance (including performance incentives) and the potential for component obsolescence in connection with long-term procurements. Changes in estimates are typically the result of schedule changes that affect performance incentives and penalties, changes in contract scope, changes in new business forecasts that can affect the level of overhead allocated to a given contract and changes in estimates on contracts as a result of the complex nature of the satellites we manufacture. Changes in estimates are included in sales and cost of sales using the cumulative catch-up method, which recognizes the cumulative effect of changes in estimates on current and prior periods in the current period based on a contract's completion percentage. Provisions for losses on contracts are recorded when estimates determine that a loss will be incurred on a contract at completion. Under firm fixed-price contracts, work performed and products shipped are paid for at a fixed price without adjustment for actual costs incurred in connection with the contract; accordingly, favorable changes in estimates in a period will result in additional revenue and profit, and unfavorable changes in estimates will result in a reduction of revenue and profit or the recording of a loss that will be borne solely by us. For the three months ended March 31, 2012 and 2011, cumulative catch up adjustments related to prior year activity as a result of changes in contract estimates increased operating income by $17 million and $4 million, respectively, and diluted earnings per share by $0.34 and $0.07, respectively.

Significant estimates also include the allowances for doubtful accounts and long-term receivables, estimated useful lives of our plant and equipment and finite lived intangible assets, the fair value of stock based compensation, the realization of deferred tax assets, uncertain tax positions, the fair value of and gains or losses on derivative instruments and our pension liabilities.

Concentration Of Credit Risk

Financial instruments which potentially subject us to concentrations of credit risk consist principally of cash and cash equivalents, contracts-in-process and long-term receivables. Our cash and cash equivalents are maintained with high-credit-quality financial institutions. Historically, our customers have been primarily large multinational corporations and U.S. and foreign governments for which the creditworthiness was generally substantial. In recent years, we have added commercial customers which are highly leveraged, as well as those in the development stage which are partially funded. Management believes that its credit evaluation, approval and monitoring processes combined with contractual billing arrangements and our title interest in satellites under construction provide for management of potential credit risks with regard to our current customer base. However, swings in the global financial markets that include illiquidity, market volatility, changes in interest rates, and currency exchange fluctuations can be difficult to predict and negatively affect certain customers' ability to make payments when due.

Fair Value Measurements

U.S. GAAP defines fair value as the price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants. U.S. GAAP also establishes a fair value hierarchy that gives the highest priority to observable inputs and the lowest priority to unobservable inputs. The three levels of the fair value hierarchy are described below:

Level 1: Inputs represent a fair value that is derived from unadjusted quoted prices for identical assets or liabilities traded in active markets at the measurement date.

Level 2: Inputs represent a fair value that is derived from quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities, and pricing inputs, other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date.

Level 3: Inputs are generally unobservable and typically reflect management's estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models, and similar techniques.

Assets And Liabilities Measured At Fair Value On A Recurring Basis

The following table presents our assets and liabilities measured at fair value on a recurring basis at March 31, 2012 (in thousands):

	Level 1		Level 2		Level 3
Assets:
Cash equivalents
Money market funds	$	506,190	$	—	$	—
Available-for-sale securities
Communications industry	$	689	$	—	$	—
Non-qualified pension plan assets	$	587	$	—	$	—
Liabilities:
Derivatives
Foreign exchange contracts	$	—	$	5,268	$	—

The Company does not have any non-financial assets or non-financial liabilities that are recognized or disclosed at fair value on a recurring basis as of March 31, 2012.

Assets And Liabilities Measured At Fair Value On A Non-recurring Basis

We review the carrying values of our equity method investments when events and circumstances warrant and consider all available evidence in evaluating when declines in fair value are other than temporary. The fair values of our investments are determined based on valuation techniques using the best information available and may include quoted market prices, market comparables and discounted cash flow projections. An impairment charge is recorded when the carrying amount of the investment exceeds its current fair value and is determined to be other than temporary.
