Notes to portfolio of investments

Security valuation
The net asset value of the common shares of the Fund is determined daily as of the close of the New York Stock Exchange (NYSE), normally at 4:00 P.M., Eastern Time. Short-term debt investments that have a remaining maturity of 60 days or less are valued at amortized cost, and thereafter assume a constant amortization to maturity of any discount or premium, which approximates market value. All other securities held by the Fund are valued at the last sale price or official closing price (closing bid price or last evaluated quote if no sale has occurred) as of the close of business on the principal securities exchange (domestic or foreign) on which they trade or, lacking any sales, at the closing bid price. Securities traded only in the over-the-counter market are valued at the last bid price quoted by brokers making markets in the securities at the close of trading. Securities for which there are no such quotations, principally debt securities, are valued based on the evaluated prices provided by an independent pricing service, which utilizes both dealer-supplied and electronic data processing techniques, which take into account factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics and other market data.

Other assets and securities for which no such quotations are readily available are valued at fair value as determined in good faith under consistently applied procedures established by and under the general supervision of the Board of Trustees. Generally, trading in non-U.S. securities is substantially completed each day at various times prior to the close of trading on the NYSE. The values of such securities used in computing the net asset value of the Fund’s shares are generally determined as of such times. Occasionally, significant events that affect the values of such securities may occur between the times at which such values are generally determined and the close of the NYSE. Upon such an occurrence, these securities will be valued at fair value as determined in good faith under consistently applied procedures established by and under the general supervision of the Board of Trustees.

In deciding whether to make a fair value adjustment to the price of a security, the Board of Trustees or their designee may review a variety of factors, including developments in foreign markets, the performance of U.S. securities markets and the performance of instruments trading in U.S. markets that represent foreign securities and baskets of foreign securities. The Fund may also fair value securities in other situations, for example, when a particular foreign market is closed, but the Fund is calculating the net asset value. In view of these factors, it is likely that a Fund investing significant amounts of assets in securities in foreign markets will be fair valued more frequently than a Fund investing significant amounts of assets in frequently traded, U.S. exchange listed securities of large-capitalization U.S. issuers.

For purposes of determining when fair value adjustments may be appropriate with respect to investments in securities in foreign markets that close prior to the NYSE, the Fund will, on an ongoing basis, monitor for “significant market events.” A significant market event may be a certain percentage change in the value of an index that tracks foreign markets in which the Fund has significant investments. If a significant market event occurs due to a change in the value of the index, the pricing for investments in foreign markets that have closed prior to the NYSE will promptly be reviewed and potential adjustments to the net asset value will be recommended to the Fund’s Pricing Committee where applicable.

Valuations change in response to many factors including the historical and prospective earnings of the issuer, the value of the issuer’s assets, general economic conditions, interest rates, investor perceptions and market liquidity.

The Fund adopted Statement of Financial Accounting Standards No. 157 (FAS 157), Fair Value Measurements, effective with the beginning of the Fund’s fiscal year. FAS 157 established a three-tier hierarchy to prioritize the assumptions, referred to as inputs, used in valuation


techniques to measure fair value. The three-tier hierarchy of inputs is summarized in the three broad levels listed below:

Level 1 – Quoted prices in active markets for identical securities.

Level 2 – Prices determined using other significant observable inputs. Observable inputs are inputs that other market participants would use in pricing a security. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk and others.

Level 3 – Prices determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable, such as when there is little or no market activity for an investment, unobservable inputs may be used. Unobservable inputs reflect the Fund’s own assumptions about the factors that market participants would use in pricing an investment 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 net assets as of September 30, 2008:

  Investments in    Other Financial 
Valuation Inputs  Securities   Instruments* 
  
Level 1 – Quoted Prices  $744,395,589 ($15,020)
Level 2 – Other Significant Observable Inputs  60,713,046 (101,413)
Level 3 – Significant Unobservable Inputs  4,768,750 -
Total  $809,877,385 ($116,433)

* Other financial instruments are derivative instruments not reflected in the Portfolio of Investments, such as futures, forwards and swap contracts, which are valued at the unrealized appreciation/depreciation on the instrument.

The following is a reconciliation of Level 3 assets for which significant unobservable inputs were used to determine fair value:

  Investments  Other Financial 
  in Securities  Instruments 
Balance as of December 31, 2007  $10,034,370 - 
Accrued discounts/premiums  - - 
Realized gain (loss)  - - 
Change in unrealized appreciation  4,685 - 
(depreciation)      
Net purchases (sales)  - - 
Transfers in and/or out of Level 3  (5,270,305) - 
Balance as of September 30, 2008  $4,768,750 - 

Futures
The Fund may purchase and sell financial futures contracts and options on those contracts. The Fund may invest in contracts based on financial instruments such as U.S. Treasury Bonds or Notes, or on securities indices such as the Standard & Poor’s 500 Index, in order to hedge against a decline in the value of securities owned by the Fund.


Initial margin deposits required upon entering into futures contracts are satisfied by the delivery of specific securities or cash as collateral to the broker (the Fund’s agent in acquiring the futures position). If the position is closed out by an opposite position prior to the settlement date of the futures contract, a final determination of variation margin is made, cash is required to be paid to or released by the broker, and the Fund realizes a gain or loss.

When the Fund sells a futures contract based on a financial instrument, the Fund becomes obligated to deliver that kind of instrument at an agreed upon date for a specified price. The Fund realizes a gain or loss depending on whether the price of an offsetting purchase is less or more than the price of the initial sale, or on whether the price of an offsetting sale is more or less than the price of the initial purchase. The Fund could be exposed to risks if it could not close out futures positions because of an illiquid secondary market or the inability of counterparties to meet the terms of their contracts. Futures contracts are valued at the quoted daily settlement prices established by the exchange on which they trade.

Swap contracts
The Fund may enter into swap transactions in order to hedge the value of the Fund’s portfolio against interest rate fluctuations or to enhance the Fund’s income or to manage the Fund’s exposure to credit or market risk.

Credit default swaps involve the exchange of a fixed rate premium for protection against the loss in value of an underlying debt instrument in the event of a defined credit event (such as payment default or bankruptcy). Under the terms of the swap, one party acts as a “guarantor” receiving a periodic payment that is a fixed percentage applied to a notional principal amount. In return the party agrees to purchase the notional amount of the underlying instrument, at par, if a credit event occurs during the term of the swap. The Fund may enter into credit default swaps in which either it or its counterparty act as guarantors. By acting as the guarantor of a swap, the Fund assumes the market and credit risk of the underlying instrument including liquidity and loss of value.

The Fund records changes in the value of the swap as unrealized gains or losses on swap contracts. Net periodic payments accrued but not yet received (paid) are included in change in the unrealized appreciation/depreciation. Accrued interest income and interest expense on the swap contracts are recorded as realized gain (loss). Any upfront payments received by the Fund are amortized to maturity.

Swap contracts are subject to risks related to the counterparty’s ability to perform under the contract, and may decline in value if the counterparty’s creditworthiness deteriorates. The risks may arise from unanticipated movement in interest rates. The Fund may also suffer losses if it is unable to terminate outstanding swap contracts or reduce its exposure through offsetting transactions.
