FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

The Company categorizes its assets and liabilities measured at fair value into a fair value hierarchy that prioritizes the inputs used in pricing the asset or liability. The three levels of the fair value hierarchy are:

• Level 1: Observable inputs obtained from independent sources, such as quoted prices for identical assets and liabilities in active markets.

• Level 2: Other inputs that are observable directly or indirectly, such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and inputs that are derived principally from or corroborated by observable market data. The fair value of the Company's Level 2 financial assets are primarily obtained from observable market prices for identical underlying securities that may not be actively traded. Certain of these securities may have different market prices from multiple market data sources, in which case an average market price is used.

• Level 3: Unobservable inputs for which there is little or no market data and require the Company to develop its own assumptions, based on the best information available in the circumstances, about the assumptions market participants would use in pricing the assets or liabilities. See below for a discussion of fair value measurements made using Level 3 inputs.

The following tables present the Company's assets and liabilities that are measured at fair value on a recurring basis:

There are no gains or losses included in earnings for the three months ended March 31, 2012 relating to the Company's assets and liabilities that are measured at fair value on a recurring basis using significant unobservable inputs.

Auction rate security

The Company's auction rate security is valued by discounting the estimated future cash flow streams of the security over the life of the security. Credit spreads and other risk factors are also considered in establishing fair value. The cost basis of the auction rate security is $10.0 million, with gross unrealized losses of $1.4 million and $1.9 million at March 31, 2013 and December 31, 2012, respectively. The unrealized losses are included in "Accumulated other comprehensive loss" in the accompanying consolidated balance sheet. At March 31, 2013, the auction rate security is rated A-/WR and matures in 2035. The Company does not consider the auction rate security to be other-than-temporarily impaired at March 31, 2013, due to its high credit rating and because the Company does not intend to sell this security, and it is not more likely than not that the Company will be required to sell this security, before the recovery of its amortized cost basis, which may be maturity.

Contingent Consideration Arrangement

The contingent consideration arrangement arose from the acquisition of Twoo in the first quarter of 2013 (see Note 3 for additional information). The fair value of the contingent consideration arrangement was determined using a probability-weighted analysis, and reflects a discount rate of 15%, which captures the risks associated with the obligation. The probability-weighted analysis consists of the Company's multi-scenario forecasts of Twoo's earnings and the number of users of Twoo.com in accordance with the contingent consideration arrangement through December 31, 2015, and the Company's estimate of the probability of each scenario occurring. These multi-scenario forecasts and related probability assessments were based primarily on management's internal projections and strategic plans, with limited additional consideration given to growth trends of similarly situated businesses. The fair value of the contingent consideration arrangement is sensitive to changes in the discount rate and changes in the forecasts of earnings and website users. The Company will remeasure the fair value of the contingent consideration arrangement each reporting period, and changes will be recognized in “General and administrative expense” in the Company's consolidated statement of operations. During the first quarter of 2013, the fair value of the contingent consideration arrangement increased by $1.5 million due to interest accretion. The contingent consideration arrangement liability at March 31, 2013 includes a current portion of $1.3 million and non-current portion of $41.0 million, which are included in “Accrued expenses and other current liabilities” and “Other long-term liabilities,” respectively, in the accompanying consolidated balance sheet.

Assets measured at fair value on a nonrecurring basis

The Company's non-financial assets, such as goodwill, intangible assets and property and equipment, as well as equity and cost method investments, are adjusted to fair value only when an impairment charge is recognized. Such fair value measurements are based predominantly on Level 3 inputs.
