Notes to financial statements
(unaudited)

Note 1 — Organization

John Hancock Tax-Advantaged Dividend Income Fund (the Fund) is a closed-end diversified management investment company registered under the Investment Company Act of 1940, as amended (the 1940 Act). The Fund began operations on February 27, 2004.

Note 2 — Significant accounting policies

The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from those estimates. Events or transactions occurring after the end of the fiscal period through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. The following summarizes the significant accounting policies of the Fund:

Security valuation. Investments are stated at value as of the close of regular trading on the New York Stock Exchange (NYSE), normally at 4:00 P.M., Eastern Time. The Fund uses a three-tier hierarchy to prioritize the pricing assumptions, referred to as inputs, used in valuation techniques to measure fair value. Level 1 includes securities valued using quoted prices in active markets for identical securities. Level 2 includes securities valued using significant observable inputs. Observable inputs may include quoted prices for similar securities, interest rates, prepayment speeds and credit risk. Prices for securities valued using these inputs are received from independent pricing vendors and brokers and are based on an evaluation of the inputs described. Level 3 includes securities valued using significant unobservable inputs when market prices are not readily available or reliable, including the Fund’s own assumptions in determining the fair value of investments. Factors used in determining value may include market or issuer specific events, changes in interest rates and credit quality. 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 values by input classification of the Fund’s investments as of April 30, 2011, by major security category or type:

Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. During the six-month period ended April 30, 2011, there were no significant transfers in or out of Level 1 or Level 2 assets.

The following is a reconciliation of Level 3 assets for which significant unobservable inputs were used to determine fair value. Transfers in or out of Level 3 represent the beginning value of any security or instrument where a change in the level has occurred from the beginning to the end of the period.

* Change in unrealized appreciation (depreciation) attributable to Level 3 securities held at period end.

In order to value the securities, the Fund uses the following valuation techniques. Equity securities held by the Fund are valued at the last sale price or official closing price on the principal securities exchange on which they trade. In the event there were no sales during the day or closing prices are not available, then securities are valued using the last quoted bid or evaluated price. Foreign securities are valued in U.S. dollars, based on foreign currency exchange rates supplied by an independent pricing service. Certain 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. Certain short-term securities are valued at amortized cost. Other portfolio securities and assets, where market quotations are not readily available, are valued at fair value, as determined in good faith by the Fund’s Pricing Committee, following procedures established by the Board of Trustees.

Repurchase agreements. The Fund may enter into repurchase agreements. When the Fund enters into a repurchase agreement, it receives collateral which is held in a segregated account by the Fund’s custodian. The collateral amount is marked-to-market and monitored on a daily basis to ensure that the collateral held is in an amount not less than the principal amount of the repurchase agreement plus any accrued interest. In the event of a default by the counterparty, realization of the collateral proceeds could be delayed, during which time the collateral value may decline.

Security transactions and related investment income. Investment security transactions are accounted for on a trade date plus one basis for daily net asset value calculations. However, for financial reporting purposes, investment transactions are reported on trade date. Interest income is accrued as earned. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds from litigation. Dividend income is recorded on the ex-date, except for dividends of foreign securities where the dividend may not be known until after the ex-date. In those cases, dividend income is recorded when the Fund becomes aware of the dividends.

Overdrafts. Pursuant to the custodian agreement, the Fund’s custodian may, in its discretion, advance funds to the Fund to make properly authorized payments. When such payments result in an overdraft, the Fund is obligated to repay the custodian for any overdraft, including any costs or expenses associated with the overdraft. The custodian has a lien, security interest or security entitlement in any Fund property, that is not segregated, to the maximum extent permitted by law to the extent of any overdraft.

Expenses. The majority of expenses are directly attributable to an individual fund. Expenses that are not readily attributable to a specific fund are allocated among all funds in an equitable manner, taking into consideration, among other things, the nature and type of expense and the fund’s relative assets. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Federal income taxes. The Fund intends to continue to qualify as a regulated investment company by complying with the applicable provisions of the Internal Revenue Code and will not be subject to federal income tax on taxable income that is distributed to shareholders. Therefore, no federal income tax provision is required.

For federal income tax purposes, the Fund has a capital loss carryforward of $86,583,009 available to offset future net realized capital gains as of October 31, 2010. The loss carryforward expires as follows: October 31, 2016 — $6,628,913 and October 31, 2017 — $79,954,096.

Under the recently enacted Regulated Investment Company Modernization Act of 2010, the Fund will be permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 for an unlimited period. However, any losses incurred during those future taxable years will be required to be utilized prior to the losses incurred in pre-enactment taxable years. As a result of this ordering rule, pre-enactment capital loss carryforwards may be more likely to expire unused. Additionally, post-enactment capital losses that are carried forward will retain their character as either short-term or long-term capital losses rather than being considered all short-term as under previous law.

As of October 31, 2010, the Fund had no uncertain tax positions that would require financial statement recognition, de-recognition or disclosure. The Fund’s federal tax returns are subject to examination by the Internal Revenue Service for a period of three years.

Distribution of income and gains. Distributions to shareholders from net investment income and net realized gains, if any, are recorded on the ex-date. The Fund generally declares and pays dividends monthly and capital gain distributions, if any, annually.

Such distributions, on a tax basis, are determined in conformity with income tax regulations, which may differ from accounting principles generally accepted in the United States of America.

Capital accounts within financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Temporary book-tax differences, if any, will reverse in a subsequent period. Book-tax differences are primarily attributable to derivative transactions, wash sales loss deferrals and characterization of distributions.

Statement of cash flows. Information on financial transactions that have been settled through the receipt and disbursement of cash is presented in the Statement of Cash Flows. The cash amount shown in the Statement of Cash Flows is the amount included in the Fund’s Statement of Assets and Liabilities and represents the cash on hand at its custodian and does not include any short-term investments.

Note 3 — Derivative instruments

The Fund may invest in derivatives in order to meet its investment objectives. The use of derivatives may involve risks different from, or potentially greater than, the risks associated with investing directly in securities. Specifically, derivatives expose the 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 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 the Fund will succeed in enforcing them.

Options. There are two types of options, a put option and a call option. Options are traded either over-the-counter or on an exchange. A call option gives the purchaser of the option the right to buy (and the seller the obligation to sell) the underlying instrument at the exercise price. A put option gives the purchaser of the option the right to sell (and the writer the obligation to buy) the underlying instrument at the exercise price. Writing puts and buying calls may increase the Fund’s exposure to changes in the value of the underlying instrument. Buying puts and writing calls may decrease the Fund’s exposure to such changes. Risks related to the use of options include the loss of the premium, possible illiquidity of the options markets, trading restrictions imposed by an exchange and movements in underlying security values, and for written options, potential losses in excess of the amounts recognized on the Statement of Assets and Liabilities.

Options listed on an exchange are valued at their closing price. If no closing price is available, then they are valued at the mean between the last bid and ask prices from the exchange on which they are principally traded. For options not listed on an exchange, an independent pricing source is used to value the options at the mean between the last bid and ask prices. When the Fund purchases an option, the premium paid by the Fund is included in the Portfolio of Investments and subsequently “marked-to-market” to reflect current market value. If the purchased option expires, the Fund realizes a loss equal to the cost of the option. If the Fund exercises a call option, the cost of the securities acquired by exercising the call is increased by the premium paid to buy the call. If the

Fund exercises a put option, it realizes a gain or loss from the sale of the underlying security and the proceeds from such sale are decreased by the premium paid. If the Fund enters into a closing sale transaction, the Fund realizes a gain or loss, depending on whether proceeds from the closing sale are greater or less than the original cost. When the Fund writes an option, the premium received is included as a liability and subsequently “marked-to-market” to reflect current market value of the option written. Premiums received from writing options that expire unexercised are recorded as realized gains. Premiums received from writing options which are exercised or are closed are added to or offset against the proceeds or amount paid on the transaction to determine the realized gain or loss. If a put option on a security is exercised, the premium received reduces the cost basis of the securities purchased by the Fund.

During the six months ended April 30, 2011, the Fund wrote option contracts to seek to generate income and to reduce overall volatility of the underlying portfolio. The following tables summarize the Fund’s written options activities during the six months ended April 30, 2011 and the contracts held at April 30, 2011.

Interest rate swaps. Interest rate swaps represent an agreement between a Fund and counterparty to exchange cash flows based on the difference between two interest rates applied to a notional amount. 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 interest receivable or payable under the swap contracts on a periodic basis. Upfront payments made/received by the Fund are amortized/accreted for financial reporting purposes, with the unamortized/unaccreted portion included in the Statement of Assets and Liabilities. Swaps are marked-to-market daily based upon values from third party vendors or brokers quotations, and the change in value is recorded as unrealized appreciation/depreciation of swap contracts. A termination payment by the counterparty or the Fund is recorded as realized gain or loss, as well as the net periodic payments received or paid by a Fund.

Entering into swap agreements involves, to varying degrees, elements of credit, market and documentation risk that may amount to values that are in excess of the amounts recognized on the Statement of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for the swap, that a counterparty may default on its obligation or delay payment under the swap terms. The counterparty may disagree or contest the terms of the swap. Market risks may also accompany the swap, including interest rate risk. The Fund may also suffer losses if it is unable to terminate or assign outstanding swaps or reduce its exposure through offsetting transactions.

During the six months ended April 30, 2011, the Fund used interest rate swaps to hedge financing costs. During the six months ended April 30, 2011, the Fund held interest rate swaps with total USD notional amounts up to $95,000,000, as measured at each quarter end.

There were no open interest rate swap contracts at April 30, 2011.

Note 4 — Guarantees and indemnifications

Under the Fund’s organizational documents, its Officers and Trustees are indemnified against certain liabilities arising out of the performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts with service providers that contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. The risk of material loss from such claims is considered remote.

Note 5 — Fees and transactions with affiliates

John Hancock Advisers, LLC (the Adviser) serves as investment adviser for the Fund. The Adviser is an indirect wholly owned subsidiary of Manulife Financial Corporation (MFC).

Management fee. The Fund has an investment management agreement with the Adviser under which the Fund pays a daily management fee to the Adviser equivalent, on an annual basis, to 0.75% of the Fund’s average daily net assets and the value attributed to the Committed Facility Agreement (see Note 8) (collectively, managed assets). The Adviser has subadvisory agreements with John Hancock Asset Management a division of Manulife Asset Management (US) LLC (formerly MFC Global Investment Management (U.S.), LLC), an indirectly owned subsidiary of MFC and an affiliate of the Adviser, and Analytic Investors LLC. The Fund is not responsible for payment of the subadvisory fees.

The Adviser has contractually agreed to limit the Fund’s management fee to the following: 0.60% of the Fund’s average daily managed assets from February 27, 2009 until February 26, 2010, 0.65% of such assets from February 27, 2010 until February 26, 2011 and 0.70% of average daily managed assets from February 27, 2011 until February 26, 2012. Accordingly, the expense reductions related to the reduction in the management fee amounted to $394,194 for the six months ended April 30, 2011.

The investment management fees incurred for the six months ended April 30, 2011 were equivalent to an annual effective rate of 0.67% of the Fund’s average daily managed assets.

Accounting and legal services. Pursuant to a service agreement, the Fund reimburses the Adviser for all expenses associated with providing the administrative, financial, legal, accounting and recordkeeping services of the Fund, including the preparation of all tax returns, periodic reports to shareholders and regulatory reports, among other services. These accounting and legal services fees incurred for the six months ended April 30, 2011, amounted to an annual rate of 0.01% of the Fund’s average daily net assets.

Trustee expenses. The Trust compensates each Trustee who is not an employee of the Adviser or its affiliates. These Trustees may, for tax purposes, elect to defer receipt of this compensation under the John Hancock Group of Funds Deferred Compensation Plan (the Plan). Deferred amounts are invested in various John Hancock funds and remain in the funds until distributed in accordance with the Plan. The investment of deferred amounts and the offsetting liability are included within Other receivables and prepaid expenses and Payable to affiliates — Trustees’ fees, respectively, in the accompanying Statement of Assets and Liabilities.

Note 6 — Fund share transactions

In December 2007, the Trustees approved a share repurchase plan, which has been subsequently reviewed and approved by the Board of Trustees each year in December. Under the share repurchase plan, the Fund may repurchase in the open market up to 10% of its outstanding common shares. The plan will remain in effect between January 1, 2011 and December 31, 2011.

During the six months period ended April 30, 2011 and year ended October 31, 2010, the Fund repurchased 225,571 and 302,900, respectively (0.60% and 0.79% of shares outstanding, respectively) of its common shares under the share repurchase program. The corresponding dollar amount of the share repurchase amounted to $3,391,487 and $4,178,919 during the six-month periods ended April 30, 2011 and year ended October 31, 2010, respectively.

Note 7 — Leverage risk

The Fund utilizes a Committed Facility Agreement (CFA) to increase its assets available for investment. When the Fund leverages its assets, common shareholders bear the fees associated with the facility and have the potential to benefit or be disadvantaged from the use of leverage.

The Adviser’s fee is also increased in dollar terms from the use of leverage. Consequently, the Fund and the Adviser may have differing interests in determining whether to leverage the Fund’s assets. Leverage creates risks that may adversely affect the return for the holders of common shares, including:

• the likelihood of greater volatility of net asset value and market price of common shares

• fluctuations in the interest rate paid for the use of the credit facility

• increased operating costs, which may reduce the Fund’s total return

• the potential for a decline in the value of an investment acquired through leverage, while the Fund’s obligations under such leverage remains fixed

• the Fund is more likely to have to sell securities in a volatile market in order to meet asset coverage or other debt compliance requirements

To the extent the income or capital appreciation derived from securities purchased with funds received from leverage exceeds the cost of leverage, the Fund’s return will be greater than if leverage had not been used, conversely, returns would be lower if the cost of the leverage exceeds the income or capital appreciation derived.

Note 8 — Committed Facility Agreement

The Fund has entered into a Committed Facility Agreement (CFA) with a subsidiary of BNP Paribas (BNP) that allows it to borrow up to $344 million and to invest the borrowings in accordance with its investment practices. Prior to April 29, 2011, the Fund could borrow up to $351 million under the CFA.

Borrowings under the CFA are secured by the assets of the Fund as disclosed in the Fund’s investments. Interest charged is at the rate of one-month LIBOR (reset daily) plus 0.70% and is payable monthly. Prior to April 29, 2011, the interest rate was one-month LIBOR plus 0.85%. The Fund also pays a commitment fee of 0.60% per annum on the unused portion of the facility. The commitment fee for the six months ended April 30, 2011, totaled $85,070 and is included in the interest expense in the Statement of operations. As of April 30, 2011, the Fund had borrowings of $337,000,000 at an interest rate of 0.91%, which are reflected on the Statement of Assets and Liabilities. During the six months ended April 30, 2011, the average borrowing under the CFA and the effective average interest rate were $322,722,652 and 1.12%, respectively.

The Fund may terminate the agreement with 90 days’ notice and, if the Board of Trustees determines that the elimination of all indebtedness leveraging the Fund’s investments is in the best interests of the Fund’s shareholders, the Fund may terminate the agreement with 30 days’ notice. In addition, if certain asset coverage and collateral requirements, minimum net assets or other covenants are not met, the CFA could be deemed in default and result in termination. Absent a default or a facility termination event, BNP is required to provide the Fund with 270 days’ notice prior to terminating or amending the CFA.

The Fund has entered into an agreement with BNP that allows BNP to borrow a portion of the pledged collateral (Lent Securities) in an amount not to exceed the lesser of: (i) outstanding borrowings owed by the Fund to BNP and (ii) thirty-three and one-third percent of the Fund’s total assets. The Fund can designate any security within the pledged collateral as ineligible to be a Lent

Security and can recall any of the Lent Securities. The Fund also has the right to apply and set-off an amount equal to one hundred percent (100%) of the then-current fair market value of such Lent Securities against the current borrowings under the CFA in the event that BNP fails to timely return the Lent Securities and in certain other circumstances. Income earned from Lent Securities is recorded as a component of interest income on the Statement of operations. During the six months ended April 30, 2011, the Fund recorded $495,359 in income from Lent Securities.

Note 9 — Purchase and sale of securities

Purchases and sales of securities, other than short-term securities, aggregated $91,376,431 and $72,338,527, respectively, for the six months ended April 30, 2011.

Note 10 — Other matters

On August 30, 2010, a derivative complaint was filed in the Superior Court of The Commonwealth of Massachusetts, Suffolk County, on behalf of a purported shareholder of John Hancock Tax-Advantaged Dividend Income Fund, which was like one filed for another John Hancock Fund.

A Joint Motion To Dismiss With Prejudice was filed on February 28, 2011 in the Business Litigation Session of the Superior Court of The Commonwealth of Massachusetts, Suffolk County. On March 1, 2011, the Court granted the Motion to Dismiss with Prejudice.

For the six months ended April 30, 2011, the results of operations include non-recurring legal fees and expenses of approximately $101,450 related to this matter, which are included in Professional fees on the Statement of operations. During the period, the Fund recorded reimbursement from its insurance provider of $495,358, which is included in expense reductions on the Statement of operations.

Investment objective and policy

The Fund’s investment objective is to provide a high level of after-tax total return from dividend income and gains and capital appreciation.

Under normal market conditions, the Fund will invest at least 80% of its assets (net assets plus borrowings for investment purposes) in dividend-paying common and preferred securities that the Adviser believes at the time of acquisition are eligible to pay dividends which, for individual shareholders, qualify for U.S. federal income taxation at rates applicable to long-term capital gains, which currently are taxed at a maximum rate of 15% (“tax-advantaged dividends”). Tax-advantaged dividends generally include dividends from domestic corporations and dividends from foreign corporations that meet certain specified criteria. The Fund generally can pass the tax treatment of tax-advantaged dividends it receives through to its common shareholders.

On December 17, 2007, the Fund’s Trustees approved a change to the Fund’s investment policy regarding investments in foreign securities. The revised policy provides that the Fund may invest up to 40% of its net assets in securities of corporate and government issuers located outside the United States that are traded or denominated in U.S. dollars.

On March 31, 2008, the shareholders approved the following changes to the Fund’s fundamental investment policy: To eliminate the Fund’s “concentration” policy (i.e., investing at least 25% of its net assets) with respect to securities issued by financial services corporations; and to modify the Fund’s concentration policy with respect to investing in the utilities sector by permitting the Fund to invest in both U.S. and foreign utilities corporations, rather than only U.S. utilities corporations (as required under the prior policy).

On December 9, 2008, the Fund’s Trustees approved the following investment policy: The fund may write (sell) covered call index options on up to 30% of the value of the fund’s total assets.

On March 9, 2011, the Board of Trustees amended the Fund’s investment policy regarding the use of reverse repurchase agreement transactions. The new policy provides the following:

Reverse repurchase agreements. The Fund may engage in reverse repurchase agreement transactions to the extent permitted under the Investment Company Act of 1940, as amended (“1940 Act”), and related guidance of the Securities and Exchange Commission and its staff. The Fund intends to use reverse repurchase agreements to obtain investment leverage either alone and/or in combination with other forms of investment leverage. The Fund may also use reverse repurchase agreement transactions for temporary or emergency purposes. In a reverse repurchase agreement transaction, the Fund temporarily transfers possession of a portfolio instrument to another party in return for cash. At the same time, the Fund agrees to repurchase the instrument at an agreed upon time and price, which reflects an interest payment. The value of the portfolio securities transferred may substantially exceed the purchase price received by the Fund under the reverse repurchase agreement transaction and, during the life of the reverse repurchase agreement transaction, the Fund may be required to transfer additional securities if the market value of those securities initially transferred declines. In engaging in a reverse repurchase transaction, the Fund may transfer (“sell”) any of its portfolio securities to a broker-dealer, bank or another financial institution counterparty as determined by the Adviser to be appropriate. In accordance with guidance from the SEC and its staff from time to time in effect, the Fund will earmark or segregate liquid assets equal to repayment obligations under the reverse repurchase agreements. When the Fund enters into a reverse repurchase agreement transaction, any fluctuations in the market value of either the securities transferred to another party or the securities in which the proceeds may

be invested would affect the market value of the Fund’s assets. As a result, such transactions may increase fluctuations in the market value of the Fund’s assets.

Bylaws

Effective September 9, 2008, the Fund’s bylaws were amended with respect to notice requirements for Trustee nominations and other proposals by the Fund’s shareholders. These provisions require the disclosure of the nominating shareholder and the nominee’s investment interests as they relate to the Fund, as well as the name of any other shareholder supporting the nominee for election as a Trustee or the proposal of other business. In order for notice to be proper, such notice must disclose the economic interests of the nominating shareholder and nominee, including his or her holdings of shares in the Fund, the intent upon which those shares were acquired, and any hedging arrangements (including leveraged or short positions) made with respect to the shares of the Fund. Additionally, any material interest that the shareholder has in the business to be brought before the meeting must be disclosed.

Dividends and distributions

During the six-month period ended April 30, 2011, dividends from net investment income totaling $0.5460 per share were paid to shareholders. The dates of payments and the amounts per share were as follows:

Dividend reinvestment plan

The Board of Trustees approved certain amendments to the Fund’s Dividend Reinvestment Plan. The Dividend Reinvestment Plan that is in effect as of July 1, 2011 is described below.

Pursuant to the Fund’s Dividend Reinvestment Plan (the Plan), distributions of dividends and capital gains are automatically reinvested in common shares of the Fund by The Bank of New York Mellon (the Plan Agent). Every shareholder holding at least one full share of the Fund is entitled to participate in the Plan. In addition, every shareholder who became a shareholder of the Fund after June 30, 2011 and holds at least one full share of the Fund will be automatically enrolled in the Plan. Shareholders who do not participate in the Plan will receive all distributions in cash.

If the Fund declares a dividend or distribution payable either in cash or in common shares of the Fund and the market price of shares on the payment date for the distribution or dividend equals or exceeds the Fund’s net asset value per share (NAV), the Fund will issue common shares to participants at a value equal to the higher of NAV or 95% of the market price. The number of additional shares to be credited to each participant’s account will be determined by dividing the dollar amount of the distribution or dividend by the higher of NAV or 95% of the market price. If the market price is lower than NAV, or if dividends or distributions are payable only in cash, then participants will receive shares purchased by the Plan Agent on participants’ behalf on the New York Stock Exchange (the NYSE) or otherwise on the open market. If the market price exceeds NAV before the Plan Agent has completed its purchases, the average per share purchase price may exceed NAV, resulting in fewer shares being acquired than if the Fund had issued new shares.

There are no brokerage charges with respect to common shares issued directly by the Fund. However, whenever shares are purchased or sold on the NYSE or otherwise on the open market, each participant will pay a pro rata portion of brokerage trading fees, currently $0.05 per share purchased or sold. Brokerage trading fees will be deducted from amounts to be invested.

The reinvestment of dividends and net capital gains distributions does not relieve participants of any income tax that may be payable on such dividends or distributions.

Shareholders participating in the Plan may buy additional shares of the Fund through the Plan at any time in amounts of at least $50 per investment, up to a maximum of $10,000, with a total calendar year limit of $100,000. Shareholders will be charged a $5 transaction fee plus $0.05 per share brokerage trading fee for each order. Purchases of additional shares of the Fund will be made on the open market. Shareholders who elect to utilize monthly electronic fund transfers to buy additional shares of the Fund will be charged a $2 transaction fee plus $0.05 per share brokerage trading fee for each automatic purchase. Shareholders can also sell Fund shares held in the Plan account at any time by contacting the Plan Agent by telephone, in writing or by visiting the Plan Agent’s Web site at www.bnymellon.com/shareowner/equityaccess. The Plan Agent will mail a check to you (less applicable brokerage trading fees) on settlement date, which is three business days after your shares have been sold. If you choose to sell your shares through your stockbroker, you will need to request that the Plan Agent electronically transfer your shares to your stockbroker through the Direct Registration System.

Shareholders participating in the Plan may withdraw from the Plan at any time by contacting the Plan Agent by telephone, in writing or by visiting the Plan Agent’s Web site at www.bnymellon.com/shareowner/equityaccess. Such termination will be effective immediately if the notice is received by the Plan Agent prior to any dividend or distribution record date; otherwise, such termination will be effective on the first trading day after the payment date for such dividend or distribution, with respect to any subsequent dividend or distribution. If you withdraw, your shares will be credited to your account; or, if you wish, the Plan Agent will sell your full and fractional shares and send you the proceeds, less a transaction fee of $5.00 and less brokerage trading fees of $0.05 per share. If a shareholder does not maintain at least one whole share of common stock in the Plan account, the Plan Agent may terminate such shareholder’s participation in the Plan after written notice. Upon termination, shareholders will be sent a check for the cash value of any fractional share in the Plan account, less any applicable broker commissions and taxes.

Shareholders who hold at least one full share of the Fund may join the Plan by notifying the Plan Agent by telephone, in writing or by visiting the Plan Agent’s Web site at www.bnymellon.com/shareowner/equityaccess. If received in proper form by the Plan Agent before the record date of a dividend, the election will be effective with respect to all dividends paid after such record date. If you wish to participate in the Plan and your shares are held in the name of a brokerage firm, bank or other nominee, please contact your nominee to see if it will participate in the Plan for you. If you wish to participate in the Plan, but your brokerage firm, bank or other nominee is unable to participate on your behalf, you will need to request that your shares be re-registered in your own name, or you will not be able to participate. The Plan Agent will administer the Plan on the basis of the number of shares certified from time to time by you as representing the total amount registered in your name and held for your account by your nominee.

Experience under the Plan may indicate that changes are desirable. Accordingly, the Fund and the Plan Agent reserve the right to amend or terminate the Plan. Participants generally will receive written notice at least 90 days before the effective date of any amendment. In the case of termination, participants will receive written notice at least 90 days before the record date for the payment of any dividend or distribution by the Fund.
