Financial Instruments And Marketable Securities [Abstract]

Financial Instruments And Marketable Securities

Note 2. Financial Instruments and Marketable Securities

We follow a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (Level 1) and the lowest priority to measurements involving significant unobservable inputs (Level 3). The three levels of the fair value hierarchy are as follows:

• Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities.

• Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, included in Level 1 that are observable either directly or indirectly.

• Level 3 inputs are unobservable for the asset or liability, but are based upon our own assumptions used to measure assets and liabilities at fair value.

The level in the fair value hierarchy within which a fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety.

The following table presents the placement in the fair value hierarchy of assets that are measured at fair value on a recurring basis:

		$00,000		$00,000		$00,000		$00,000
December 31, 2011:	Total		Level 1		Level 2		Level 3
Common stock	$	320		320		0		0
Government and agency securities		26,845		26,845		0		0
Total available-for-sale securities	$	27,165		27,165		0		0

		$00,000		$00,000		$00,000		$00,000
December 31, 2010:	Total		Level 1		Level 2		Level 3
Common stock	$	223		223		0		0
State and municipal bonds		5,152		0		5,152		0
Government and agency securities		25,844		25,844		0		0
Total available-for-sale securities	$	31,219		26,067		5,152		0

There were no transfers between levels during 2011 and 2010.

As of year end, our financial assets that are measured at fair value on a recurring basis are common stock and debt securities. The government and agency securities have a maturity of twelve months.

Marketable securities, all treated as available-for-sale securities, consist of the following:

			Gross		Gross
