Fair Value Measurement of Assets and Liabilities
 
5. Fair Value Measurement of Assets and Liabilities
 
Accounting guidance defines fair value, establishes a framework for measuring fair value, and expands disclosure requirements about fair value measurements. The accounting guidance does not mandate any new fair-value measurements and is applicable to assets and liabilities that are required to be recorded at fair value under other accounting pronouncements.
 
The three levels of the fair-value hierarchy are described as follows:
 
Level 1: Quoted prices (unadjusted) in active markets for identical assets and liabilities. As of June 30, 2012 and December 31, 2011, we had no level 1 assets or liabilities.
 
Level 2: Inputs other than Level 1 that are observable, either directly or indirectly. As of June 30, 2012 and December 31, 2011, we had no level 2 assets or liabilities.
 
Level 3: Inputs other than Level 1 that are observable, either directly or indirectly. As of June 30, 2012 and December 31, 2011, we had no level 3 assets or liabilities.
