13. Fair Value

Fair value represents the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. We measure our financial assets and liabilities in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value.

·

Level 1—valuations for assets and liabilities traded in active exchange markets, or interest in open-end mutual funds that allow a company to sell its ownership interest back at net asset value on a daily basis. Valuations are obtained from readily available pricing sources for market transactions involving identical assets, liabilities or funds.

·

Level 2—valuations for assets and liabilities traded in less active dealer or broker markets, such as quoted prices for similar assets or liabilities or quoted prices in markets that are not active. Level 2 includes U.S. Treasury, U.S. government and agency debt securities, and certain corporate obligations. Valuations are usually obtained from third-party pricing services for identical or comparable assets or liabilities.

·

Level 3—valuations for assets and liabilities that are derived from other valuation methodologies, such as option pricing models, discounted cash flow models and similar techniques, and not based on market exchange, dealer, or broker traded transactions. Level 3 valuations incorporate certain assumptions and projections in determining the fair value assigned to such assets or liabilities.

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 and intangible 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.

We have Level 1 financial assets measured at fair value consisting of money market funds in the amount of $5.0 million as of September 30, 2016 and December 31, 2015. These assets are included in cash and cash equivalents in the accompanying condensed consolidated balance sheet.
