3. Fair values of assets and liabilities

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.

The tables below present the balances of our assets and liabilities measured at fair value on a recurring basis as of April 30, 2016 and January 30, 2016 (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 April 30, 2016, we held equity investments in two privately-held venture capital funded technology companies and an equity investment in one joint venture, with an aggregate carrying value of $2.6 million. During the three months ending April 30, 2016, we recorded an impairment charge of $0.3 million in connection with one of our privately-held investments as we concluded the impairment to be other-than-temporary.

We did not identify any other events or changes in circumstances that may have had a significant adverse effect on the fair value of these investments during the three months ended April 30, 2016 and May 2, 2015. 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.
