4. Fair Value Measurements, Marketable Securities and Variable Interest Entities

Fair value is defined as the price that would be received on sale of an asset or paid to transfer a liability (exit price) in an orderly transaction between market participants at the measurement date. The FASB has established a fair value hierarchy that distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (2) an entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3).

The three levels of the fair value hierarchy under the guidance for fair value measurement are described below:

Level 1 — Inputs are unadjusted quoted prices in active markets for identical assets or liabilities. Pricing inputs are based upon quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. The valuations are based on quoted prices of the underlying security that are readily and regularly available in an active market, and accordingly, a significant degree of judgment is not required. As of December 31, 2015, the Company used Level 1 assumptions for its money market funds.

Level 2 — Pricing inputs are 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 or can be corroborated by observable market data for substantially the full term of the assets or liabilities. As of December 31, 2015, the Company used Level 2 assumptions for its acquisition-related promissory note and revolving loan facility.

Level 3 — Pricing inputs are generally unobservable for the assets or liabilities and include situations where there is little, if any, market activity for the investment. The inputs into the determination of fair value require management’s judgment or estimation of assumptions that market participants would use in pricing the assets or liabilities. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models, and similar techniques. As of December 31, 2015, the Company did not have any Level 3 financial assets or liabilities.

The Company’s financial instruments as of December 31, 2015 and June 30, 2015 were categorized as follows in the fair value hierarchy (in thousands):

(1)	These liabilities are carried at historical cost on the Company's condensed consolidated balance sheets.

Marketable Securities

All liquid investments with maturities of three months or less at the date of purchase are classified as cash equivalents. Investments with maturities greater than three months at the date of purchase are classified as marketable securities. Historically, the Company’s marketable securities have been classified and accounted for as available-for-sale. Management determines the appropriate classification of its investments at the time of purchase and reevaluates the available-for-sale designation as of each balance sheet date. Available-for-sale securities are carried at fair value, with unrealized gains and losses, net of tax, reported as a component of accumulated other comprehensive loss within stockholders’ equity.

The Company holds money market funds of $20.2 million as of December 31, 2015 and June 30, 2015. Gross unrealized gains and losses were not material as the carrying value approximated estimated fair value due to its short maturities. The Company did not hold any marketable securities as of December 31, 2015 and June 30, 2015.

The Company did not realize any material gains or losses from sales of its securities in the three and six months ended December 31, 2015 and 2014. As of December 31, 2015 and June 30, 2015, the Company did not hold securities that had maturity dates greater than one year.

Variable Interest Entities

A VIE is consolidated by its primary beneficiary. The primary beneficiary has both the power to direct the activities that most significantly impact the entity’s economic performance and the obligation to absorb losses or the right to receive benefits from the entity that could potentially be significant to the VIE. The assessment of whether the Company is the primary beneficiary of the VIE requires significant assumptions and judgments, including the identification of significant activities and an assessment of our ability to direct those activities. The Company has an equity interest in a privately held entity that is a VIE, of which the Company is not the primary beneficiary. Accordingly, the interest of $2.5 million as of December 31, 2015 and June 30, 2015 is recognized at cost within other assets, noncurrent on the Company’s condensed consolidated balance sheets. The Company’s interest was evaluated for impairment as of December 31, 2015 and June 30, 2015 which did not result in any indications of impairment. The Company’s maximum exposure to loss as a result of the unconsolidated VIE is $2.5 million at December 31, 2015, which represents the carrying value of the Company’s investment in the VIE.
