Fair Value Measurements

Various inputs are used in determining the value of the Fund's investments. These inputs are summarized in three broad levels. Level 1 includes quoted prices in active markets for identical securities. Level 2 includes other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, and credit risk). Level 3 includes significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments). The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. Securities held by the fund are reflected as Level 2 because the securities are valued at amortized cost (which approximates fair value) and, accordingly, the inputs used to determine value are not quoted prices in an active market.

The following is a summary of the inputs used as of March 31, 2013 in valuing the Fund's investments.

Assets	Level 1		Level 2		Level 3		Total
Investments in Securities (i)	$	—	$	23,870,172,118	$	—	$	23,870,172,118
Repurchase Agreements		—		795,694,768		—		795,694,768
Total	$	—	$	24,665,866,886	$	—	$	24,665,866,886

There have been no transfers between fair value measurement levels during the period ended March 31, 2013.
