3.             Fair values of assets and liabilities

Fair value is defined as, “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price).” The accounting standards establish a consistent framework for measuring fair value and disclosure requirements about fair value measurements and among other things, require us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

Fair value hierarchy

The accounting standards discuss valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flow), and the cost approach (cost to replace the service capacity of an asset or replacement cost). The standards utilize a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels:

● Level 1 - Valuation is based upon quoted prices for identical instruments traded in active markets.

● Level 2 - Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.

● Level 3 - Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect our estimate of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models, and similar techniques.

Determination of fair value

Our cash equivalents and marketable securities are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency. The types of marketable securities valued based on quoted market prices in active markets include most U.S. government and agency securities, sovereign government obligations, money market securities and certain corporate obligations with high credit ratings and an ongoing trading market.

Our foreign currency derivative instruments were classified as Level 2 because they are valued using quoted prices and other observable data of similar instruments in active markets.

The tables below present the balances of our assets and liabilities measured at fair value on a recurring basis as of August 2, 2014 and February 1, 2014 (in thousands):

Assets measured and recorded at fair value on a non-recurring basis

Our non-marketable preferred stock investments in privately-held venture capital funded technology companies are recorded at cost and are adjusted to fair value only in the event that they become other-than-temporarily impaired. As of August 2, 2014, we held equity investments in three privately-held venture capital funded technology companies and an equity investment in one joint venture, with an aggregate carrying value of $3.3 million. As of August 2, 2014, we did not identify any events or changes in circumstances that may have had a significant adverse effect on the fair value of these investments. Each of these equity investments in privately-held companies constituted less than a 20% ownership position. Furthermore, we do not believe that we have the ability to exert significant influence over any of these companies.
