Fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. There is an established hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability and are developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the assumptions about the factors that market participants would use in valuing the asset or liability.

The Company’s cash and investment instruments are classified within Level 1 or Level 2 of the fair value hierarchy based on quoted prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency.

Level 1 includes financial instruments for which quoted market prices for identical instruments are available in active markets. Level 1 assets of the Company include money market funds and U.S. Treasury securities as they are traded with sufficient volume and frequency of transactions.

Level 2 includes financial instruments for which the valuations are based on quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities. Level 2 instruments of the Company generally include certain U.S. and foreign government and agency securities, commercial paper, corporate and municipal bonds and notes, asset-backed securities, and foreign currency forward contracts. To estimate their fair value, the Company utilizes pricing models based on market data. The significant inputs for the valuation model usually include benchmark yields, reported trades, broker and dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data, and industry and economic events.

Level 3 includes financial instruments for which fair value is derived from valuation based on inputs that are unobservable and significant to the overall fair value measurement. As of June 27, 2015 and June 28, 2014, the Company did not hold any Level 3 investment securities.

Foreign Currency Forward Contracts

The Company has foreign subsidiaries that operate and sell the Company’s products in various markets around the world. As a result, the Company is exposed to foreign exchange risks. The Company utilizes foreign exchange forward contracts and other instruments to manage foreign currency risk associated with foreign currency denominated monetary assets and liabilities, primarily certain short-term intercompany receivables and payables, and to reduce the volatility of earnings and cash flows related to foreign-currency transactions.

The forward contracts, most with a term of less than 120 days, were transacted near quarter end; therefore, the fair value of the contracts as of both June 27, 2015 and June 28, 2014 is not significant. The change in the fair value of these foreign currency forward contracts is recorded as gain or loss in the Company’s Consolidated Statements of Operations as a component of Interest and other income (expense), net.
