Fair Value Measurements

Fair Value Measurements

The FASB literature regarding fair value measurements for certain assets and liabilities establishes a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires entities to maximize the use of “observable inputs” and minimize the use of “unobservable inputs.” The three levels of inputs used to measure fair value are as follows:

•Level 1—Quoted prices in active markets for identical assets or liabilities;

•Level 2—Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets or other inputs that are observable or can be corroborated by observable market data; and

•Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities, including certain pricing models, discounted cash flow methodologies, and similar techniques that use significant unobservable inputs.

Fair Value Measurements on a Recurring Basis

The table below segregates all of our financial assets and liabilities that are measured at fair value on a recurring basis into the most appropriate level within the fair value hierarchy based on the inputs used to determine the fair value at the measurement date (amounts in millions):

Foreign Currency Forward Contracts

Foreign Currency Forward Contracts Designated as Hedges (“Cash Flow Hedges”)

The total gross notional amounts and fair values of our Cash Flow Hedges, all of which have remaining maturities of 11 months or less, are as follows (amounts in millions):
