Investments, All Other Investments [Abstract]
Financial Instruments	Financial Instruments Certain financial assets and liabilities are accounted for at fair value, which is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The following fair value hierarchy prioritizes the inputs used to measure fair value: Level 1 – Quoted prices are available in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2 – Pricing inputs are other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. Level 3 – Pricing inputs include significant inputs that are generally less observable from objective sources. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value from the perspective of a market participant.

Share-Based Compensation [Abstract]
Shared-based Compensation	Shared-based Compensation Stock Options: The Company has issued non-qualified and incentive stock options to employees and nonemployee directors. The fair value of these options are estimated on the date of grant using the Black-Scholes option pricing model, which requires estimates of the expected term of the option, the expected volatility of the price of the Company’s common stock, dividend yield and the risk-free interest rate. Options outstanding as of June 30, 2015 vest over a period of three years with an expiration term of ten years.
