Investments as of June 30, 2009 (Unaudited)

(†) Debt securities (other than short-term obligations purchased with an original or remaining maturity of sixty days or less) are generally valued on the basis of evaluated bids furnished to the Fund by a pricing service recommended by the investment adviser and approved by the Board of Trustees, which service determines valuations for normal, institutional size-trading units of such securities using market information, transactions for comparable securities and various relationships between securities which are generally recognized by institutional traders. Equity securities, including closed-end investment companies and exchange-traded funds, for which market quotations are readily available, are valued at market value, as reported by pricing services recommended by the investment adviser and approved by the Board of Trustees. Such pricing services generally use the security’s last sale price on the exchange or market where the security is primarily traded or, if there is no reported sale during the day, the closing bid price. Securities traded on the NASDAQ Global Select Market, NASDAQ Global Market and NASDAQ Capital Market are valued at the NASDAQ Official Closing Price (“NOCP”), or if lacking a NOCP, at the most recent bid quotation on the applicable NASDAQ Market. Broker-dealer bid quotations may also be used to value debt and equity securities where a pricing service does not price a security or where a pricing service does not provide a reliable price for the security. In instances where broker-dealer bid quotations are not available, certain securities held by the Fund may be valued on the basis of a price provided by a principal market maker. Short-term obligations purchased with an original or remaining maturity of sixty days or less are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available are valued at fair value as determined in good faith by the Fund’s investment adviser using consistently applied procedures under the general supervision of the Board of Trustees. Investments in other open-end investment companies are valued at their net asset value each day.

The Fund may hold securities traded in foreign markets. Foreign securities are valued at the market price in the foreign market. However, if events occurring after the close of the foreign market (but before the close of regular trading on the New York Stock Exchange) are believed to materially affect the value of those securities, such securities are fair valued pursuant to procedures approved by the Board of Trustees. When fair valuing securities, the Fund may, among other things, use modeling tools or other processes that may take into account factors such as securities market activity and/or significant events that occur after the close of the foreign market and before the Fund calculates its net asset value.

The books and records of the Fund are maintained in U.S. dollars. The value of securities, currencies and other assets and liabilities denominated in currencies other than U.S. dollars are translated into U.S. dollars based upon foreign exchange rates prevailing at the end of the period.

(a) Federal Tax Information (Amounts exclude certain adjustments made at the end of the Fund’s fiscal year for tax purposes. Such adjustments are primarily due to wash sales. Amortization of premium on debt securities is excluded for tax purposes.):

At June 30, 2009, the net unrealized depreciation on investments based on a cost of $223,699,456 for federal income tax purposes was as follows:

Aggregate gross unrealized appreciation for all investments in which there is an excess of value over tax cost	$	8,790,523
Aggregate gross unrealized depreciation for all investments in which there is an excess of tax cost over value		(10,598,916	)
Net unrealized depreciation	$	(1,808,393	)

At September 30, 2008, the Fund had a capital loss carryforward of approximately $19,696,181 of which $19,514,453 expires on September 30, 2010 and $181,728 expires on September 30, 2014. These amounts may be available to offset future realized capital gains, if any, to the extent provided by regulations.

(b) Variable rate security. Rate as of June 30, 2009 is disclosed.

(c) Illiquid security. At June 30, 2009, the value of this security amounted to $1,036,044 or 0.5% of net assets.

(d) The Fund’s investment in mortgage related securities of the Federal Home Loan Mortgage Corporation, Federal National Mortgage Association and Government National Mortgage Association are interests in separate pools of mortgages. All separate investments in securities of each issuer which have the same coupon rate have been aggregated for the purpose of presentation in the Portfolio of Investments.

(e) Non-income producing security.

(f) Future dividend payments have been eliminated as the issuer has been placed in conservatorship.

(g) Rate represents discount rate at time of purchase.

(h) It is the Fund’s policy that the market value of the collateral for repurchase agreements be at least equal to 102% of the repurchase price, including interest. The repurchase agreements are tri-party arrangements whereby the collateral is held in a segregated account for the benefit of the Fund and on behalf of the counterparty. Repurchase agreements could involve certain risks in the event of default or insolvency of the counterparty including possible delays or restrictions upon a Fund’s ability to dispose of the underlying securities.

144A   Securities exempt from registration under Rule 144A of the Securities Act of 1933. These securities may be resold in transactions exempt from registration, normally to qualified institutional buyers. At June 30, 2009, the value of these securities amounted to $17,551,339 or 7.9% of net assets.

Fair Value Measurements

The Fund adopted Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157 (“FAS 157”), Fair Value Measurements, effective October 1, 2008. FAS 157 establishes a hierarchy for net asset value determination purposes in which various inputs are used in determining the value of the Fund’s investments. These inputs are summarized in the three broad levels listed below:

• Level 1 — quoted prices in active markets for identical investments;

• Level 2 — prices determined using other significant observable inputs that are observable either directly, or indirectly through corroboration with observable market data (which could include quoted prices for similar investments, interest rates, credit risk, etc.);

• Level 3 — prices determined using significant unobservable inputs for situations where quoted prices or observable inputs are unavailable such as when there is little or no market activity for an investment (unobservable inputs reflect the Fund’s own assumptions in determining the fair value of investments and would be based on the best information available).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used to value the Fund’s investments as of June 30, 2009, at value:
