Notes to Portfolio of Investments (unaudited)

Security valuation
Investments are stated at value as of the close of the regular trading on the New York Stock Exchange (NYSE), normally at 4:00 p.m., Eastern Time. Equity securities held by the Fund are valued at the last sale price or official closing price (closing bid price or last evaluated price if no sale has occurred) as of the close of business on the principal securities exchange (domestic or foreign) on which they trade. Debt obligations 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. Foreign securities and currencies are valued in U.S. dollars, based on foreign currency exchange rates supplied by an independent pricing service. 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. Equity and debt obligations, for which there are no prices available from an independent pricing service, are valued based on broker quotes or fair valued as described below. 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.

Other portfolio securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by the Fund’s Pricing Committee in accordance with procedures adopted by 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.

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 and market 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.

5 


The following is a summary of the inputs used to value the Fund’s net assets as of April 30, 2009:

  Investments in   Other Financial  
Valuation Inputs         Securities      Instruments*  
 
Level 1 – Quoted Prices  $396,084,528   
Level 2 – Other Significant Observable Inputs  72,918,447                 ($6,146,532) 
Level 3 – Significant Unobservable Inputs  14,950,595   
Total  $483,953,570                 ($6,146,532) 

* Other financial instruments are derivative instruments not reflected in the Fund of Investments, such as futures, forwards and swap contracts, which are stated at valued based upon futures’ settlement prices, foreign currency exchange forward rates and swap prices.

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

  Investments in   Other Financial  
    Securities     Instruments

The Fund has adopted the provisions of Statement of Financial Accounting Standards No. 161. “Disclosures about Derivative Instruments and Hedging Activities – an Amendment of FASB Statement No. 133” (FAS 161). This Statement changes the disclosure requirements for derivative instruments and hedging activities. The Fund is now required to provide enhanced disclosures about (a) how and why the Fund uses derivative instruments, (b) how derivative instruments are accounted for under Statement 133 and its related interpretations, and (c) how derivative instruments affect the Fund’s financial position, financial performance, and cash flows. All changes to disclosure have been made in accordance with the Statement and incorporated for the current period as part of the Notes to the Portfolio of Investments included below.

Swap contracts
The Fund may enter into interest rate, credit default, cross- currency, and other forms of swap transactions to manage its exposure to credit, currency and interest rate risks or to enhance the Fund’s income. Swap agreements are privately negotiated agreements between a Fund and a counterparty to exchange investment cash flows, assets, foreign currencies or market-linked returns at specified, future intervals. In connection with these agreements, the fund will hold cash or identify securities equal to the net amount, if any, of the Fund's obligations with respect to the swap agreements to provide assets of value and recourse in the event of default or bankruptcy/insolvency.

Swaps are marked to market daily based upon values from third party vendors or quotations from market makers to the extent available and the change in value, if any, is recorded as an unrealized appreciation/depreciation of swap contracts on the Statements of Assets and Liabilities. In the event that market quotations are not readily available or deemed reliable, certain swap agreements may be valued at fair value as determined in good faith by the Trust’s Pricing Committee in accordance with procedures adopted by the Board of Trustees.

6 


Entering into swap agreements involves, to varying degrees, elements of credit, market, counterparty and documentation risk in excess of the amounts recognized on the Statements of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of contractual terms in the agreements and that there may be unfavorable changes in interest or exchange rates. The Fund may also suffer losses if it is unable to terminate outstanding swap contracts, or reduce its exposure through offsetting transactions, or the Fund may be liable for early termination of the derivative.

The Fund is a party to International Swap Dealers Association, Inc., Master Agreements (“ISDA Master Agreements”) with select counterparties that govern over the counter derivative transactions, which may include foreign exchange derivative transactions, entered into by the Fund and those counterparties. The ISDA Master Agreements typically include standard representations and warranties, as well as a Credit Support Annex (“CSA”) that accompanies a schedule to ISDA master agreements provisions outlining the general obligations of the Fund and counterparties relating to events of default, termination events and other standard provisions. Termination events may include a decline in the Fund’s net asset value below a certain point over a certain period of time that is specified in the Schedule to the ISDA Master Agreement; such an event may entitle the counterparty to elect to terminate early and calculate damages based on that termination, with respect to some or all outstanding transactions under the applicable damage calculation provisions of the ISDA Master Agreement. An election by one or more counterparties to terminate ISDA Master Agreements could have a material impact on the financial statements of the Fund.

Interest rate swap agreements
Interest rate swaps represent an agreement between two counterparties to exchange cash flows based on the difference in the two interest rates, applied to the notional principal amount for a specified period. The payment flows are usually netted against each other, with the difference being paid by one party to the other. The Fund settles accrued net receivable or payable under the swap contracts on a periodic basis.

During the period the fund held interest rate swaps to hedge against anticipated interest rate changes. The Fund had the following interest rate swap contracts open on April 30, 2009:

  Rate Type       
NOTIONAL  FIXED  VARIABLE  TERMINATION  COUNTERPARTY  UNREALIZED 
AMOUNT  PAYMENTS  PAYMENTS  DATE    DEPRECIATION 
  MADE BY  RECEIVED BY       
  FUND  FUND       
$70,000,000    4.37%  3-month LIBOR (a)  Nov 2010  Bank of America  ($3,301,991) 
 70,000,000    3.79%  3-month LIBOR (a)  Jan 2011  Morgan Stanley  (2,844,541) 
Total          ($6,146,532) 

(a) At April 30, 2009, the 3-month LIBOR rate was 1.0163%.

The fair values of derivatives held by the Fund at April 30, 2009 (as noted above), that are not accounted for as hedging instruments under Statement of Financial Accounting Standards, No. 133 (as amended),“Accounting for Derivative Instruments and Hedging Activities”, (FAS 133) are interest rate contracts.

Risks and uncertainties
Fixed income risk
Fixed income securities are subject to credit and interest rate risk and involve some risk of default in connection with principal and interest payments.

Derivatives and counterparty risk
The use of derivative instruments may involve risk different from, or potentially greater than, the risks associated with investing directly in securities. Specifically, derivative instruments expose a fund to the risk that the counterparty to an over-the-counter (OTC) derivatives contract will be unable or unwilling to make timely settlement payments or otherwise to honor its obligations. OTC derivatives transactions typically can only be closed out with the other party to the transaction. If the counterparty defaults, the fund will have contractual remedies, but there is no assurance that the counterparty will meet its contractual obligations or that, in the event of default, the fund will succeed in enforcing them.

Risks associated with foreign investments
Investing in securities issued by companies whose principal business activities are outside the United States may involve significant risks not present in domestic investments. For example, there is generally less publicly available information about foreign companies, particularly those not subject to the disclosure and reporting requirements of the U.S. securities laws. Foreign issuers are generally not bound by uniform accounting, auditing, and financial reporting requirements and standards of practice comparable to those applicable to domestic issuers. Investments in foreign securities also involve the risk of possible adverse changes in investment or exchange control regulations, expropriation or confiscatory taxation, limitation on the removal of Funds or other assets of the Fund, political or financial instability or diplomatic and other developments which could affect such investments. Foreign stock markets, while growing in volume and sophistication, are generally not as developed as those in the United States, and securities of some foreign issuers (particularly those located in developing countries) may be less liquid and more volatile than securities of comparable U.S. companies. In general, there is less overall governmental supervision and regulation of foreign securities markets, broker-dealers and issuers than in the United States.

Sector risk — utilities industry
The Fund may concentrate investments in a particular industry, sector of the economy or invest in a limited number of companies. The concentration is closely tied to a single sector of the economy which may cause the Fund to underperform other sectors. Specifically, utilities can be hurt by higher interest costs in connection with capital construction programs, costs associated with environmental and other regulations and the effects of economic declines, surplus capacity and increased competition. Accordingly, the concentration may make the Fund’s value more volatile and investment values may rise and fall more rapidly.

Leverage utilization risk
The Fund utilizes leverage to increase assets available for investment. The Fund has a Committed Facility Agreement (CFA) with a third party commercial bank that allows it to borrow up to an initial limit of $255 million and to invest the borrowings in accordance with its investment practices. Borrowings under the CFA are secured by the assets of the Fund.
