Fair Value Measurements
(7)           Fair Value Measurements
 
In accordance with the Fair Value Measurements Topic of the Financial Accounting Standards Board Accounting Standards Codification, the Trust established a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date.  The three levels are defined as follows:
 
          Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Trust has the ability to access at the measurement date.  An active market for the asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.  The value of the Trust’s exchange-traded futures contracts and options fall into this category.
 
         Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly.  This category includes forward currency contracts, options on forward currency contracts, and fixed income securities that the Trust values using models or other valuation methodologies derived from observable market data.


         Level 3 inputs are unobservable inputs for an asset or liability.  Unobservable inputs shall be used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date.  As of September 30, 2011 and December 31, 2010, the Trust did not have any Level 3 assets or liabilities.
 
An asset or liability’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The fair value hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3).
 
The following table presents the Trust’s fair value hierarchy for those assets and liabilities measured at fair value on a recurring basis as of September 30, 2011 and December 31, 2010, respectively:
