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 and how they are determined are defined earlier in Note 1.

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

December 31, 2013:	Total		Level 1	Level 2	Level 3
Common stock	$	451	451	—	—
Total available-for-sale securities	$	451	451	—	—

December 31, 2012:	Total		Level 1	Level 2	Level 3
Common stock	$	354	354	—	—
Total available-for-sale securities	$	354	354	—	—

There were no transfers between levels during 2013 and 2012.

As of December 31, 2013, our financial assets that are measured at fair value on a recurring basis include only common stock. 

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

December 31, 2013:	Amortized Cost		Gross Unrealized Gains	Gross Unrealized Losses	Fair Value
Common stock	$	197	254	—	451
Total available-for-sale securities	$	197	254	—	451

December 31, 2012:	Amortized Cost		Gross Unrealized Gains	Gross Unrealized Losses	Fair Value
Common stock	$	197	157	—	354
Total available-for-sale securities	$	197	157	—	354

The unrealized gains and losses recorded in accumulated other comprehensive income and the realized gains and losses recorded in earnings were immaterial during the three years reported in these consolidated financial statements.

Future maturities of our available-for-sale securities consist of the following:

	Less than 12 months			Greater than 12 months
December 31, 2013:	Amortized Cost		Fair Value	Amortized Cost	Fair Value
Common stock	$	197	451	—	—
Total available-for-sale securities	$	197	451	—	—
