Marketable Securities and Fair Value Measurements

Note 3. Marketable Securities and Fair Value Measurements

Marketable Securities

The Company’s marketable securities are classified as available-for-sale securities and, accordingly, are recorded at fair value. The difference between amortized cost and fair value is included in stockholders’ equity.

The Company’s marketable securities at September 30, 2013 and March 31, 2013 are invested in the following:

	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Market Value

Fair Value Hierarchy

Fair value is defined as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three categories:

Level 1: Quoted market prices in active markets for identical assets or liabilities.

Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs that are not corroborated by market data.

Level 1 primarily consists of financial instruments whose values are based on quoted market prices such as exchange-traded instruments and listed equities.

Level 2 includes financial instruments that are valued using models or other valuation methodologies. These models are primarily industry-standard models that consider various assumptions, including time value, yield curve, volatility factors, prepayment speeds, default rates, loss severity, current market and contractual prices for the underlying financial instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace, can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace.

Level 3 is comprised of unobservable inputs that are supported by little or no market activity. Financial assets are considered Level 3 when their fair values are determined using pricing models, discounted cash flows or similar techniques and at least one significant model assumption or input is unobservable.

The following table presents the Company’s financial instruments recorded at fair value in the consolidated balance sheet, classified according to the three categories described above:

	Level 1		Level 2		Level 3		Total

In May 2013, the Company invested $0.8 million in preferred stock of a private technology company. In addition, the Company committed to invest an additional $0.7 million if the private technology company achieves certain milestones or otherwise at the Company’s option. This other investment is accounted for using the cost method and is measured at fair value on a nonrecurring basis only if there are identified events or changes in circumstance that may have a significant adverse effect on the fair value of these investments. The aggregate carrying amount of this other investment was $0.8 million as of September 30, 2013 and is classified within other assets in the unaudited condensed consolidated balance sheets.
