Fair Value Measurements [Abstract]  
Fair Value Measurements
H.            Fair Value Measurements

The Company measures financial and non-financial assets and liabilities at fair value in accordance with ASC 820, Fair Value Measurements and Disclosures.  These measurements involve various valuation techniques and assume that the transactions would occur between market participants in the most advantageous market for the Company. 
 
Fair Value Hierarchy
 
The three levels of inputs that may be used to measure fair value are as follows:
 
Level 1.                          Quoted prices in active markets for identical assets and liabilities
Level 2.                          Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in less active markets, or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated with observable market data for substantially the full term of the assets or liabilities. Level 2 inputs also include non-binding market consensus prices that can be corroborated with observable market data, as well as quoted prices that were adjusted for security-specific restrictions.
Level 3.                          Unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of assets or liabilities. Level 3 inputs also include non-binding market consensus prices or non-binding broker quotes that we were unable to corroborate with observable market data.

The following is a summary of valuation techniques utilized by the Company for its significant financial and non-financial assets and liabilities as of March 31, 2015 and December 31, 2014:
 
Assets
 
To estimate the fair value of its equity and U.S. Treasury securities, the Company obtains current market pricing from quoted market sources or uses pricing for identical securities. Assets measured at fair value on a recurring basis are summarized below (in thousands).

The Company also has assets that may be subject to measurement at fair value on a non-recurring basis, including goodwill and intangible assets, and other long-lived assets. The Company reviews the carrying value of these assets whenever events and circumstances indicate that the carrying amounts of the assets may not be recoverable. If it is determined that the assets are impaired, the carrying value would be reduced to estimated fair value.
