Fair Value [Abstract]
Fair Value	Note 13 – Fair Value Fair value is defined as 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. A three-tier fair value hierarchy of inputs is employed to determine fair value measurements. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets and liabilities. Level 2 inputs are observable prices that are not quoted on active exchanges, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. Level 3 inputs are unobservable inputs employed for measuring the fair value of assets or liabilities. This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. The carrying amounts of cash equivalents, accounts receivable, accrued liabilities, accounts payable and capital lease obligations approximate fair value. As of June 30, 2015, $1.0 million (par value) of long-term investments were recorded at fair value using Level 3 inputs.

Note 13 – Fair Value

Fair value is defined as 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. A three-tier fair value hierarchy of inputs is employed to determine fair value measurements. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets and liabilities. Level 2 inputs are observable prices that are not quoted on active exchanges, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. Level 3 inputs are unobservable inputs employed for measuring the fair value of assets or liabilities. This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value.

The carrying amounts of cash equivalents, accounts receivable, accrued liabilities, accounts payable and capital lease obligations approximate fair value. As of June 30, 2015, $1.0 million (par value) of long-term investments were recorded at fair value using Level 3 inputs.
