[1] The Fund maintains U.S. Treasury Bills generally with an original maturity of 90 days, which are classified as cash equivalents. For the year ended December 31, 2011, U.S. Treasury Bills had an original maturity greater than 90 days. Management has decided to present this balance as a cash equivalent for consistency purposes as the nature and use of this balance has remained constant. Further, proceeds from the maturity of the January 12, 2012 U.S. Treasury Bills were used to purchase U.S. Treasury Bills with a 90 day maturity, which will be classified as cash equivalents.
