The various inputs that are used in determining the fair value of the Fund’s investments are summarized into the three broad levels listed below.

• Level 1 – quoted prices in active markets for identical securities

• Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

• Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input both individually and in the aggregate that is significant to the fair value measurement. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following table represents each valuation input as presented on the Schedule of Portfolio Investments (“SOI”) (amounts in thousands):

	Level 1 Quoted prices		Level 2 Other significant observable inputs		Level 3 Significant unobservable inputs		Total
Total Investments in Securities (a)	$	1,517,328	$	11,489	$	—	$	1,528,817

(a) All portfolio holdings designated as Level 1 and Level 2 are disclosed individually in the SOI. Level 2 consists of certain ADRs, the report value of which is an evaluated price. Please refer to the SOI for industry specifics of portfolio holdings.

There were no transfers between Levels 1 and 2 during the period ended September 30, 2012.
