(4) Fair Value Measurements 

A fair value hierarchy has been established which requires the Company to maximize the use of observable inputs, where available, and minimize the use of unobservable inputs when measuring fair value. The fair value hierarchy describes three levels of inputs that may be used to measure fair value: 

Level 1	Quoted prices in active markets for identical assets or liabilities.
Level 2	Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3	Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The following table sets forth the financial assets and liabilities that were measured at fair value on a recurring basis at June 30, 2014, by level within the fair value hierarchy. The assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

The Company’s long-term investments have been classified as Level 2, which have been initially valued at the transaction price and subsequently revalued, at the end of each reporting period, utilizing a third party pricing service. The pricing service utilizes industry standard valuation models and observable market inputs to determine value that include surveying the bond dealer community, obtaining benchmark quotes, incorporating relevant trade data, and updating spreads daily. There have been no transfers of assets or liabilities between the fair value measurement classifications.

			Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs		Significant Unobservable
June 30, 2014	Total		(Level 1)		(Level 2)		Inputs (Level 3)

Long-term investments available-for-sale		10.0		—		10.0		—
Total	$	46.9	$	36.9	$	10.0	$	—

Cash equivalents consist primarily of money market funds. Long-term investments consist of U.S. agency securities and U.S. Treasury securities, classified as available-for-sale and have maturities greater than 365 days from the date of acquisition.

The Company has had no realized gains or losses from the sale of investments for the twelve months ended June 30, 2014. The following table shows the unrealized gains and losses and fair values for those investments as of June 30, 2014 and June 30, 2013 aggregated by major security type:

			Unrealized		Unrealized

As of June 30, 2014, the Company had investments in an unrealized loss position. The Company has determined that the unrealized losses below $0.1 milllion on these investments at June 30, 2014 are temporary in nature and expects the security to mature at its stated maturity principal. All available-for-sale securities held at June 30, 2014 will mature in over one year.
