Fair Value	13. Fair Value We report certain financial assets and liabilities at their carrying amounts. The carrying amounts of our financial instruments, which include cash and cash equivalents, accounts receivable, restricted cash, accounts payable, and accrued liabilities approximate fair value because of their short maturities. Certain assets, including goodwill, intangible assets and other long-lived assets are also subject to measurement at fair value on a nonrecurring basis, if they are deemed to be impaired as the result of an impairment review.

As of March 31, 2016, Level 1 financial assets measured at fair value was $5.0 million, consisting of money market funds, which are included in cash and cash equivalents in our consolidated balance sheet.
