Assets and Liabilities Measured at Fair Value
For assets and liabilities required to be reported at fair value, GAAP provides a hierarchy that prioritizes inputs to valuation techniques used to measure fair value into three broad levels. Level 1 inputs are quoted market prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 inputs are inputs, other than quoted market prices included within Level 1, that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability.






The Company's assets and liabilities measured at fair value are as follows:

(a)
In the first quarter of 2012, we entered into a forward contract to sell 12 million Expedia, Inc. shares at approximately $34 per share. The derivative contract was in a liability position in the prior year as the stock price of Expedia, Inc. shares had increased since the inception of the derivative contract and resulted in a recognition of unrealized losses on the contract in the prior year. The contract was settled during the fourth quarter of 2012.
