Fair Value Measurements

3 Months Ended

Mar. 31, 2015

The Company categorizes its assets 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 such as quoted prices for identical assets and liabilities in active markets obtained from independent sources.

•

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 values of the Company’s level 2 securities are primarily obtained from observable market prices for identical underlying securities that may not be actively traded.


•	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 asset or liability.

The Company has no liabilities that are measured at fair value on a recurring basis. The following tables present the Company’s assets that are measured at fair value on a recurring basis:

Assets measured at fair value on a nonrecurring basis

The Company’s non-financial assets, such as intangible assets and property and equipment, are not required to be measured at fair value on a recurring basis. The Company evaluates the recoverability of its indefinite-lived intangible asset by performing impairment tests on an annual basis, as of each October 1, or when events or changes in circumstances indicate that the carrying amounts may not be recoverable. Any resulting asset impairment requires that the asset be recorded at its fair value. The Company's valuation methods to determine fair value utilize significant Level 3 unobservable inputs, which include discount rates, long-term growth rates and royalty rates.
