(1) – quoted prices in active markets for identical assets or liabilities (2) – observable inputs other than quoted prices in active markets for identical assets and liabilities (3) – no observable pricing inputs in the market At April 30, 2015 and July 31, 2014, the Company did not have any liabilities measured at fair value on a recurring basis. At April 30, 2015 and July 31, 2014, the Company had $9.1 million and $9.5 million, respectively, in investments in hedge funds, of which less than $0.1 million and $0.1 million, respectively, were included in “Other current assets” and $9.1 million and $9.4 million, respectively, were included in “Investments” in the accompanying consolidated balance sheets. The Company’s investments in hedge funds are accounted for using the equity method or the cost method; therefore investments in hedge funds are not measured at fair value. Fair Value of Other Financial Instruments The estimated fair value of the Company’s other financial instruments was determined using available market information or other appropriate valuation methodologies. However, considerable judgment is required in interpreting these data to develop estimates of fair value. Consequently, the estimates are not necessarily indicative of the amounts that could be realized or would be paid in a current market exchange. Cash and cash equivalents, restricted cash and cash equivalents—short-term, other current assets, revolving credit loan payable, customer deposits, notes payable—current portion and other current liabilities. At April 30, 2015 and July 31, 2014, the carrying amount of these assets and liabilities approximated fair value because of the short period of time to maturity. The fair value estimates for cash, cash equivalents and restricted cash and cash equivalents—short-term were classified as Level 1 and other current assets, revolving credit loan payable, customer deposits, notes payable—current portion and other current liabilities were classified as Level 2 of the fair value hierarchy. Restricted cash and cash equivalents—long-term. At July 31, 2014, the carrying amount of restricted cash and cash equivalents—long-term approximated fair value. The fair value was estimated based on the anticipated cash flows once the restrictions are removed, which was classified as Level 2 of the fair value hierarchy. Other assets, Notes payable—long-term portion and other liabilities. At April 30, 2015 and July 31, 2014, the carrying amount of these assets and liabilities approximated fair value. The fair values were estimated based on the Company’s assumptions, which were classified as Level 3 of the fair value hierarchy. The Company’s investments at April 30, 2015 and July 31, 2014 included investments in the equity of certain privately held entities and other investments that are accounted for at cost. It is not practicable to estimate the fair value of these investments because of the lack of a quoted market price for the shares of these entities, and the inability to estimate their fair value without incurring excessive cost. The carrying value of these investments was $3.6 million and $1.8 million at April 30, 2015 and July 31, 2014, respectively, which the Company believes was not impaired.
