Fair Value of Financial Instruments
Fair Value of Financial Instruments
Under U.S. GAAP, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., “the exit price”) in an orderly transaction between market participants at the measurement date. In determining fair value, the Company uses various valuation approaches, including quoted market prices and discounted cash flows. U.S. GAAP also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available.
Observable inputs are obtained from independent sources and can be validated by a third party, whereas, unobservable inputs reflect assumptions regarding what a third party would use in pricing an asset or liability. The fair value hierarchy is categorized into three levels based on the reliability of inputs as follows:
•
Level 1 - Valuations based on quoted prices in active markets for identical instruments that the Company is able to access. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment.
•
Level 2 - Valuations based on quoted prices in active markets for instruments that are similar, or quoted prices in markets that are not active for identical or similar instruments, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.
•
Level 3 - Valuations based on inputs that are unobservable and significant to the overall fair value measurement.

The financial assets for which the Company performs recurring fair value remeasurements are cash equivalents and short-term investments. As of September 23, 2012, financial assets utilizing Level 1 inputs included money market funds. Financial assets utilizing Level 2 inputs included certificates of deposit, corporate bonds and municipal bonds, U.S. agency securities and non-U.S. government securities. Level 2 assets are valued using a third-party pricing services consensus price which is a weighted average price based on multiple sources. These sources determine prices utilizing market income models which factor in, where applicable, transactions of similar assets in active markets, transactions of identical assets in infrequent markets, interest rates, bond or credit default swap spreads and volatility. The Company does not have any financial assets requiring the use of Level 3 inputs. There were no transfers between Level 1 and Level 2 during the three months ended September 23, 2012.

The Company utilizes specific identification in computing realized gains and losses on the sale of investments. Realized gains from the sale of investments for the three months ended September 23, 2012 of approximately $28 thousand are included in “Other non-operating income, net” and unrealized gains and losses are included as a separate component of equity, net of tax, unless the loss is determined to be “other-than-temporary.”
The Company evaluates its investments for possible impairment or a decline in fair value below cost basis that is deemed to be “other-than-temporary” on a periodic basis. It considers such factors as the length of time and extent to which fair value has been below cost basis, the financial condition of the investee, and its ability and intent to hold the investment for a period of time that may be sufficient for an anticipated recovery in market value.
