(‡) Principal Amount stated in U.S. dollars unless otherwise noted.

(†) Debt securities (other than short-term obligations purchased with an original or remaining maturity of sixty days or less) and unlisted equity securities are generally valued on the basis of evaluated bids furnished to the Fund by an independent 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.

Senior loans are priced at bid prices supplied by an independent pricing service, if available.

Equity securities, including shares of closed-end investment companies and exchange-traded funds, for which market quotations are readily available are valued at market value, as reported by independent pricing services recommended by the investment adviser and approved by the Board of Trustees. Such independent 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 and senior loans where an independent pricing service is unable to price a security or where an independent pricing service does not provide a reliable price for the security. Forward foreign currency contracts are valued utilizing interpolated prices determined from information provided by an independent pricing service.

Investments in other open-end investment companies are valued at their net asset value each day.

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.

The Fund may hold securities traded in foreign markets. Foreign securities are valued at the closing 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 values 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.

(††) Amount shown represents units. One unit represents a principal amount of 100.

(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 December 31, 2012, the net unrealized appreciation on investments based on a cost of $1,581,863,087 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	$	77,641,494
Aggregate gross unrealized depreciation for all investments in which there is an excess of tax cost over value		(4,386,248	)
Net unrealized appreciation	$	73,255,246

(b) All or a portion of this security has been designated to cover the Fund’s obligations under open TBA transactions.

(c) Variable rate security. Rate as of December 31, 2012 is disclosed.

(d) The Fund’s investment in mortgage related securities of 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) Delayed delivery. The Fund may purchase securities, including those designated as TBAs in the Portfolio of Investments, for which delivery or payment will occur at a later date, beyond the normal settlement period. The price of the security and the date when the security will be delivered and paid for are fixed at the time the transaction is negotiated. The security and the obligation to pay for it are recorded by the Fund at the time the commitment is entered into. The actual security that will be delivered to fulfill a TBA trade is not designated at the time of the trade. The security is “to be announced” 48 hours prior to the established trade settlement date. The value of the security may vary with market fluctuations during the time before the Fund takes delivery of the security. When the Fund enters into such a transaction, collateral consisting of liquid securities or cash and cash equivalents is required to be segregated or earmarked at the custodian in an amount at least equal to the amount of the Fund’s commitment. No interest accrues to the Fund until the transaction settles.

Purchases of delayed delivery securities may have a similar effect on the Fund’s net asset value as if the Fund had created a degree of leverage in the portfolio. Risks may arise upon entering into such transactions from the potential inability of counterparties to meet their obligations under the transactions. Additionally, losses may arise due to changes in the value of the underlying securities.

(f) Position is unsettled. Contract rate was not determined at December 31, 2012 and does not take effect until settlement date.

(g) 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. Certain 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	All or a portion of these securities are 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 December 31, 2012, the value of Rule 144A holdings amounted to $278,240,413 or 17.1% of net assets.

Fair Value Measurements

In accordance with accounting standards related to fair value measurements and disclosures, the Fund has categorized the inputs utilized in determining the value of the Fund’s assets or liabilities. These inputs are summarized in the three broad levels listed below:

• Level 1 - quoted prices in active markets for identical assets or liabilities;

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

• Level 3 - prices determined using significant unobservable inputs when quoted prices or observable inputs are unavailable such as when there is little or no market activity for an asset or liability (unobservable inputs reflect the Fund’s own assumptions in determining the fair value of assets or liabilities 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 December 31, 2012, at value:
