Discussion of Fund performance

By MFC Global Investment Management (U.S.), LLC

The U.S. bond market enjoyed solid gains in 2007, with most of the advance occurring in the last six months. Bonds were largely unchanged in the first half of the year, but a meltdown in the housing and mortgage markets over the last six months led to greater interest rate volatility and several interest rate cuts from the Federal Reserve. As a result, bonds rallied, with Treasury bonds delivering the best returns, while high-yield corporate bonds lagged.

“The U.S. bond market enjoyed solid
gains in 2007, with most of the
advance occurring in the last
six months.”

For the year ended December 31, 2007, John Hancock Income Securities Trust produced a total return of 1.97% at net asset value (NAV) and –6.94% at market value. The Fund’s NAV return and its market performance differ because the market share price is subject to the dynamics of secondary market trading, which could cause it to trade at a discount or premium to the Fund’s NAV share price at any time. By comparison, the average closed-end intermediate-term bond fund returned 3.43%, according to Morningstar, Inc., and the Lehman Brothers Government/Credit Bond Index returned 7.23% . The Fund’s current annualized distribution rate was 6.40% at closing NAV and 7.24% at closing market price. The portfolio’s sector weightings were the main reason behind the underperformance of the benchmark index and Morningstar peer group, primarily over the last six months. An underweight in Treasury bonds and an overweight in corporate bonds, including a healthy weighting in high yield securities, detracted from results. Within the corporate sector, our financial holdings had the biggest negative impact on performance. The most significant underperformer was real estate investment trust Public Storage REIT, Inc. which owns and operates self-storage facilities. On the positive side, beverage maker Ocean Spray Cranberries, Inc. and movie theater chain Cinemark, Inc. added value during the year. In the mortgage-backed sector, the portfolio benefited from its exposure to interest-only securities backed by “pay-option” mortgages, which generated strong returns. A steeper yield curve also boosted performance as the portfolio was positioned to benefit from this environment.

This commentary reflects the views of the portfolio managers through the end of the Fund’s period discussed in this report. The managers’ statements reflect their own opinions. As such, they are in no way guarantees of future events and are not intended to be used as investment advice or a recommendation regarding any specific security. They are also subject to change at any time as market and other conditions warrant.

Notes to Financial Highlights

¹ Based on the average of the shares outstanding.

² APS Series A and B were issued on 11-4-03.

³ Total return based on net asset value reflects changes in the Fund’s net asset value during each period. Total return based on market value reflects changes in market value. Each figure assumes that dividend and capital gain distributions, if any, were reinvested. These figures will differ depending upon the level of any discount from or premium to net asset value at which the Fund’s shares traded during the period.

⁴ Unaudited.

⁵ Ratios calculated on the basis of expenses relative to the average net assets of common shares. Without the exclusion of preferred shares, the ratios of expenses would have been 0.81%, 0.76%, 0.77%, 0.77% and 0.76% for the periods ended 12-31-03, 12-31-04, 12-31-05, 12-31-06 and 12-31-07, respectively.

⁶ Ratios calculated on the basis of net investment income relative to the average net assets of common shares. Without the exclusion of preferred shares, the ratios of net investment income would have been 5.19%, 4.99%, 5.06%, 5.45% and 5.82% for the periods ended 12-31-03, 12-31-04, 12-31-05, 12-31-06 and 12-31-07, respectively.

⁷ The portfolio turnover rate including the effect of when-issued/delayed delivery securities is 66% for the year ended December 31, 2007. Prior years exclude the effect of when-issued/delayed delivery securities.

⁸ Calculated by subtracting the Fund’s total liabilities from the Fund’s total assets and dividing that amount by the number of APS outstanding, as of the applicable 1940 Act Evaluation Date, which may differ from the financial reporting date.

Income Securities Trust | Annual report

Notes to financial statements

Note 1
Organization

John Hancock Income Securities Trust (the Fund) is a closed-end diversified investment management company registered under the Investment Company Act of 1940, as amended (the 1940 Act).

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. The following summarizes the significant accounting policies of the Fund:

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. Investments in John Hancock Cash Investment Trust (JHCIT), an affiliate of John Hancock Advisers, LLC (the Adviser), a wholly owned subsidiary of John Hancock Financial Services, Inc., a subsidiary of Manulife Financial Corporation (MFC), are valued at their net asset value each business day. 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. Debt securities whose prices cannot be provided by an independent pricing service are valued at prices provided by broker-dealers.

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.

The Fund holds securities that are valued on the basis of a price provided by a single pricing source, including broker-dealers from whom the security was purchased. The risk associated with single sourced prices is that when markets are less liquid, the price realized upon sale may be different than the price to value the security and the difference could be material to the Fund. At December 31, 2007, securities valued on the basis of a single source price amounted to 6.72% of the Fund’s net assets.

Investment risk

The Fund may invest a portion of their assets in securities of issuers that hold mortgage securities, including subprime mortgage securities. The value of these securities is sensitive to changes in economic conditions, including delinquencies and/or defaults, and may be adversely affected by shifts in the market’s perception of the issuers and changes in interest rates.

Joint repurchase agreement

Pursuant to an exemptive order issued by the Securities and Exchange Commission (SEC), the Fund, along with other registered investment companies having a management contract with the Adviser, may participate in a joint repurchase agreement transaction. Aggregate cash balances are invested in one or more large repurchase agreements, whose underlying securities are obligations of the U.S. government and/or its agencies. The Fund’s custodian bank receives delivery of the underlying securities for the joint account on the Fund’s behalf.

Annual report | Income Securities Trust

Investment transactions

Investment transactions are accounted for on a trade date plus one basis for daily net asset value calculations. However, for financial reporting purposes, investment security transactions are reported on trade date. Interest income is recorded on the accrual basis. Dividend income is recorded on the ex-dividend date net of foreign withholding taxes. Discounts/ premiums are accreted/amortized for financial reporting purposes. Realized gains and losses from investment transactions are recorded on an identified cost basis.

When-issued/delayed delivery securities

The Fund may purchase securities with delivery or payment to occur at a later date beyond the normal settlement period. At the time the Fund enters into a commitment to purchase a security, the transaction is recorded and the value of the security is reflected in the net asset value. The price of such security and the date when the security will be delivered and paid for are fixed at the time the transaction is negotiated. The value of the security may vary with market fluctuations. No interest accrues to the Fund until payment takes place. At the time the Fund enters into this type of transaction it is required to segregate cash or other liquid assets at least equal to the amount of the commitment.

Certain risks may arise upon entering into when-issued or delayed delivery securities from the potential inability of counterparties to meet the terms of their contracts or if the issuer does not issue the securities due to political, economic, or other factors. Additionally, losses may arise due to changes in the value of the underlying securities.

Guarantees and indemnifications

Under the Fund’s organizational documents, its Officers and Trustees are indemnified against certain liability 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.

Expenses

The majority of expenses are directly identifiable to an individual fund. Expenses that are not readily identifiable to a specific fund are allocated in such a manner as deemed equitable, taking into consideration, among other things, the nature and type of expense and the relative size of the funds.

Securities lending

The Fund has entered into an agreement with Morgan Stanley & Co. Incorporated and MS Securities Services Inc. (collectively, Morgan Stanley) which permits the Fund to lend securities to Morgan Stanley on a principal basis. Morgan Stanley is the primary borrower of securities of the Fund. The risk of having one primary borrower of Fund securities (as opposed to several borrowers) is that should Morgan Stanley fail financially, all securities lent will be affected by the failure and by any delays in recovery of the securities (or in the rare event, loss of rights in the collateral).

The Fund may lend portfolio securities from time to time in order to earn additional income. The Fund retains beneficial ownership of the securities it has loaned and continues to receive interest and dividends paid by the issuer of securities and to participate in any changes in their value. On the settlement date of the loan, the Fund receives collateral against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. Any cash collateral received is invested in the JHCIT. If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, a fund could experience delays and costs in recovering the securities loaned or in gaining access to the collateral. The Fund receives compensation for lending their securities either in the form of fees, guarantees, and/or by retaining a portion of interest on the investment of any cash received as collateral. Prior to May 8, 2007, the Fund paid the Adviser $465 for security lending services relating to an arrangement which ended on May 7, 2007.

Income Securities Trust | Annual report

Futures

The Fund may purchase and sell financial futures contracts and options on those contracts. The Fund invests 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. The Fund had no open financial futures contracts on December 31, 2007.

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. Interest rate swaps represent an agreement between two counter-parties 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.

The Fund records changes in the value of the swaps 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 on the Statement of Operations. Accrued interest income and interest expense on the swap contracts are recorded as realized gain (loss).

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.


The Fund had the following interest rate swap contracts open on December 31, 2007:
	RATE TYPE

Federal income taxes

The Fund qualifies 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,

Annual report | Income Securities Trust

the Fund has $9,261,520 of a capital loss carryforward available, to the extent provided by regulations, to offset future net realized capital gains. To the extent that such carryforward is used by the Fund, no capital gain distributions will be made. The loss carryforwards expire as follows: December 31, 2012 — $2,123,466, December 31, 2013 — $2,443,482, December 31, 2014 — $3,342,775, December 31, 2015 — $1,351,797. Net capital losses of $1,268,723 that are attributable to security transactions incurred after October 31, 2007, are treated as arising on January 1, the first day of the Fund’s next taxable year.

The Fund adopted the provisions of Financial Accounting Standards Board (FASB) Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement 109 (FIN 48), on January 1, 2007. FIN 48 prescribes a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return. The implementation of FIN 48 did not result in any unrecognized tax benefits in the accompanying financial statements. Each of the Fund’s federal tax returns for the prior three fiscal years remains subject to examination by the Internal Revenue Service.

New accounting pronouncement

In September 2006, FASB Standard No. 157, Fair Value Measurements (FAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishing a framework for measuring fair value and expands disclosure about fair value measurements. Management is currently evaluating the application of FAS 157 to the Fund and its impact, if any, resulting from the adoption of FAS 157 on the Fund’s financial statement disclosures.

Distribution of income and gains

The Fund records distributions to shareholders from net investment income and net realized gains, if any, on the ex-dividend date. During the year ended December 31, 2006, the tax character of distributions paid was as follows: ordinary income $14,667,522. During the year ended December 31, 2007, the tax character of distributions paid was as follows: ordinary income $15,141,022.

As of December 31, 2007, the components of distributable earnings on a tax basis included $286,646 of undistributed ordinary income.

Such distributions and distributable earnings, 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. Distributions in excess of tax basis earnings and profits, if any, are reported in the Fund’s financial statements as a return of capital.

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 will reverse in a subsequent period. Permanent differences are primarily attributable to swap derivative transactions and premium amortization.

Management fee and transactions
with affiliates and others

The Fund has an investment management contract with the Adviser. Under the investment management contract, the Fund pays a quarterly management fee to the Adviser, equivalent on an annual basis, to the sum of (a) 0.650% of the first $150,000,000 of the Fund’s average weekly net asset value and the value attributable to the Auction Preferred Shares (collectively, managed assets), (b) 0.375% of the next $50,000,000, (c) 0.350% of the next $100,000,000 and (d) 0.300% of the Fund’s average daily managed assets in excess of $300,000,000. The effective management fee rate is 0.53% of the Fund’s average managed assets for the year ended December 31, 2007. The Fund has a subadvisory agreement with MFC Global Investment Management (U.S.), LLC, a subsidiary of John Hancock Financial Services, Inc. The Fund is not responsible for payment of subadvisory fees.

The Fund has an agreement with the Adviser and affiliates to perform necessary tax, accounting, compliance, legal and other administrative services for the Fund. The compensation for the year amounted to $29,674 with an

Income Securities Trust | Annual report

effective rate of 0.01% of the Fund’s average daily managed assets.

Mr. James R. Boyle is Chairman of the Adviser, as well as affiliated Trustee of the Fund, and is compensated by the Adviser and/or its affiliates. The compensation of unaffiliated Trustees is borne by the Fund. The unaffiliated Trustees may elect to defer, for tax purposes, their receipt of this compensation under the John Hancock Group of Funds Deferred Compensation Plan. The Fund makes investments into other John Hancock funds, as applicable, to cover its liability for the deferred compensation. Investments to cover the Fund’s deferred compensation liability are recorded on the Fund’s books as an other asset. The deferred compensation liability and the related other asset are always equal and are marked to market on a periodic basis to reflect any income earned by the investments, as well as any unrealized gains or losses. The Deferred Compensation Plan investments had no impact on the operations of the Fund.

Auction preferred shares

The Fund issued a total of 3,560 Auction Preferred Shares: 1,780 shares of Series A Auction Preferred Shares and 1,780 shares of Series B Auction Preferred Shares (collectively, the Preferred Shares or APS) on November 4, 2003, in a public offering. The total offering costs of $188,388 and the total underwriting discount of $890,000 has been charged to capital paid-in of common shares during the years ended December 31, 2003 and December 31, 2004.

APS holders may be subject to auction risk. The dividend rate for the APS is normally set through an auction process, where holders may indicate the dividend rate at which they would be willing to hold or sell their APS or purchase additional APS. An auction provides liquidity for the APS; however, holders may not be able to remarket their APS at an auction. APS will not be remarketed if there are more APS offered for sale than there are buyers. If the APS are unable to be remarketed on an auction date, a maximum interest rate is applied to the APS to compensate the investor for having to hold the shares. In the case of the Fund’s APS, the maximum interest rate is the higher of 125 bps over or 125% of the 30-day “AA” Commercial Paper Rate on the date of the auction. If sufficient clearing bids do not exist at an auction, holders wishing to sell will not be able to sell all, and may not be able to sell any, of such APS in the auction. As a result, an investment in APS may be illiquid. Neither broker-dealers nor the Fund are obligated to purchase APS in an auction or otherwise, nor is the Fund required to redeem APS in the event of an unsuccessful remarketing effort at an auction.

Dividends on the APS, which accrue daily, are cumulative at a rate that was established at the offering of the APS and has been reset every seven days thereafter by an auction. Dividend rates on APS Series A ranged from 5.00% to 6.513% and Series B from 4.50% to 6.50% during the year ended December 31, 2007. Accrued dividends on APS are included

Annual report | Income Securities Trust

in the value of APS on the Fund’s Statement of Assets and Liabilities.

During the year ended December 31, 2007, APS of the Fund were successfully remarketed at each remarketing date. All remarketing efforts of APS shares occurring between February 13, 2008 and February 26, 2008 were not successful. As a result, the dividend rates for all series were reset to the maximum, which ranged from 4.17% to 4.35%.

The APS are subject to mandatory redemption at a redemption price equal to $25,000 per share, plus accumulated and unpaid dividends, if the Fund is in default on its asset coverage requirements with respect to the APS as defined in the Fund’s bylaws. Under the 1940 Act, the Fund is required to maintain asset coverage of at least 200% with respect to the Preferred Shares as of the last business day of each month in which any shares are outstanding. If the dividends on the APS shall remain unpaid in an amount equal to two full years’ dividends, the holders of the APS, as a class, have the right to elect a majority of the Board of Trustees. In general, the holders of the APS and the common shareholders have equal voting rights of one vote per share, except that the holders of the APS, as a class, vote to elect two members of the Board of Trustees, and separate class votes are required on certain matters that affect the respective interests of the APS and common shareholders.

Leverage

The Fund issued preferred shares to increase its assets available for investment. When the Fund leverages its assets, the fees paid to the Adviser for investment advisory and administrative services will be higher than if the Fund did not borrow because the Adviser’s fees are calculated based on the Fund’s total assets, including the proceeds of the issuance of preferred shares. Consequently, the Fund and the Adviser may have differing interests in determining whether to leverage the Fund’s assets.

Leverage creates risks which 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 dividend rates on any preferred shares

• increased operating costs, which may reduce the Fund’s total return to the holders of common shares

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

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, return would be lower if the cost of the leverage exceeds the income or capital appreciation derived.

Note 5
Purchase and sales of securities

Purchases and proceeds from sales or maturities of securities, other than short-term securities and obligations of the U.S. government, during the year ended December 31, 2007, aggregated $129,906,177 and $126,268,129, respectively. Purchases and proceeds from sales or maturities of obligations of the U.S. government aggregated $8,584,459 and $13,629,372, respectively, during the year ended December 31, 2007.

The cost of investments owned on December 31, 2007, including short-term investments, for federal income tax purposes was $259,344,592. Gross unrealized appreciation and depreciation of investments aggregated $3,283,198 and $7,864,338 respectively, resulting in net unrealized depreciation of $4,581,140. The difference between book basis and tax basis net unrealized appreciation of investments is attributable primarily to amortization of premiums and accretion of discounts on debt securities.

Income Securities Trust | Annual report

Investment objective and policy

The Fund is a closed-end diversified management investment company, common shares of which were initially offered to the public on February 14, 1973, and are publicly traded on the NYSE. The Fund’s investment objective is to generate a high level of current income consistent with prudent investment risk. The Fund invests in a diversified portfolio of freely marketable debt securities and may invest an amount not exceeding 20% of its assets in income-producing preferred and common stock. Under normal circumstances, the Fund will invest at least 80% of net assets in income securities. Income securities will consist of the following: (i) marketable corporate debt securities, (ii) governmental obligations and (iii) cash and commercial paper. “Net assets” is defined as net assets plus borrowings for investment purposes. The Fund will notify shareholders at least 60 days prior to any change in this 80% investment policy.

It is contemplated that at least 75% of the value of the Fund’s total assets will be represented by debt securities, which have at the time of purchase a rating within the four highest grades as determined by Moody’s Investors Service, Inc. or Standard & Poor’s Corporation. The Fund intends to engage in short-term trading and may invest in repurchase agreements. The Fund may issue a single class of senior securities not to exceed 33¹/₃% of its net assets at market value and may borrow from banks as a temporary measure for emergency purposes in amounts not to exceed 5% of the total assets at cost. The Fund may lend portfolio securities not to exceed 33¹/₃% of total assets.

Bylaws

In November 2002, the Board of Trustees adopted several amendments to the Fund’s bylaws, including provisions relating to the calling of a special meeting and requiring advance notice of shareholder proposals or nominees for Trustee. The advance notice provisions in the bylaws require shareholders to notify the Fund in writing of any proposal which they intend to present at an annual meeting of shareholders, including any nominations for Trustee, between 90 and 120 days prior to the first anniversary of the mailing date of the notice from the prior year’s annual meeting of shareholders. The notification must be in the form prescribed by the bylaws. The advance notice provisions provide the Fund and its Trustees with the opportunity to thoughtfully consider and address the matters proposed before the Fund prepares and mails its proxy statement to shareholders. Other amendments set forth the procedures that must be followed in order for a shareholder to call a special meeting of shareholders. Please contact the Secretary of the Fund for additional information about the advance notice requirements or the other amendments to the bylaws.

On August 21, 2003, shareholders approved the amendment of the Fund’s bylaws effective August 26, 2003, to provide for the issuance of preferred shares. Effective March 9, 2004, the Trustees approved additional changes to conform with the Fund’s maximum dividend rate on the preferred shares with the rate used by other John Hancock funds.

On September 14, 2004, the Trustees approved an amendment to the Fund’s bylaws increasing the maximum applicable dividend rate ceiling on the preferred shares to conform with the modern calculation methodology used by the industry and other John Hancock funds.

Financial futures contracts and options

The Fund may buy and sell financial futures contracts and options on futures contracts to hedge against the effects of fluctuations in interest rates and other market conditions. The Fund’s ability to hedge successfully will depend on the Adviser’s ability to predict accurately the future direction of interest rate changes and other market factors. There is no assurance that a liquid market for futures and options will always exist. In addition, the Fund could be prevented from opening, or realizing the benefits of closing out a futures or options position because of position limits or limits on daily price fluctuations imposed by an exchange.

Annual report | Income Securities Trust 37

The Fund will not engage in transactions in futures contracts and options on futures for speculation, but only for hedging or other permissible risk management purposes. All of the Fund’s futures contracts and options on futures will be traded on a U.S. commodity exchange or board of trade. The Fund will not engage in a transaction in futures or options on futures if, immediately thereafter, the sum of initial margin deposits on existing positions and premiums paid for options on futures would exceed 5% of the Fund’s total assets.

Dividends and distributions

During the period ended June 30, 2007, dividends from net investment income totaling $0.9200 per share were paid to shareholders. The dates of payments and the amounts per share are as follows:


	INCOME
PAYMENT DATE	DIVIDEND

March 30, 2007	$0.2225
June 29, 2007	0.2300
September 28, 2007	0.2350
December 31, 2007	0.2325

Dividend reinvestment plan

The Fund offers its common shareholders a Dividend Reinvestment Plan (the Plan), which offers the opportunity to earn compounded yields. Any holder of common shares of record of the Fund may elect to participate in the Plan and receive the Fund’s common shares in lieu of all or a portion of the cash dividends. The Plan is available to all common shareholders without charge. Mellon Investor Services (the Plan Agent) will act as agent for participating shareholders.

Shareholders may join the Plan by notifying the Plan Agent by telephone, in writing or by visiting the Plan Agent’s Web site at www.melloninvestor.com showing an election to reinvest all or a portion of dividend payments. If received in proper form by the Plan Agent prior to the record date for a dividend, the election will be effective with respect to all dividends paid after such record date. Shareholders whose shares are held in the name of a broker or nominee should contact the broker or nominee to determine whether and how they may participate in the Plan.

The Board of Trustees of the Fund will declare dividends from net investment income payable in cash or, in the case of shareholders participating in the Plan, partially or entirely in the Fund’s common shares. The number of shares to be issued for the benefit of each shareholder will be determined by dividing the amount of the cash dividend, otherwise payable to such shareholder on shares included under the Plan, by the per share net asset value of the common shares on the date for payment of the dividend, unless the net asset value per share on the payment date is less than 95% of the market price per share on that date, in which event the number of shares to be issued to a shareholder will be determined by dividing the amount of the cash dividend payable to such shareholder, by 95% of the market price per share of the common shares on the payment date. The market price of the common shares on a particular date shall be the mean between the highest and lowest sales price on the NYSE on that date. Net asset value will be determined in accordance with the established procedures of the Fund. However, if as of such payment date the market price of the common shares is lower than such net asset value per share, the number of shares to be issued will be determined on the basis of such market price. Fractional shares, carried out to four decimal places, will be credited to the shareholder’s account. Such fractional shares will be entitled to future dividends.

The shares issued to participating shareholders, including fractional shares, will be held by the Plan Agent in the name of the participant. A confirmation will be sent to each shareholder promptly, normally within five to seven days, after the payment date of the dividend. The confirmation will show the total number of shares held by such shareholder before and after the dividend, the amount of the most recent cash dividend that the shareholder has elected to reinvest and the number of shares acquired with such dividend.

Participation in the Plan may be terminated at any time by contacting the Plan Agent by telephone, in writing or by visiting the Plan Agent’s Web site, and such termination will

Income Securities Trust | Annual report

be effective immediately. However, notice of termination must be received prior to the record date of any distribution to be effective for that distribution. Upon termination, certificates will be issued representing the number of full shares of common shares held by the Plan Agent. A shareholder will receive a cash payment for any fractional share held.

The reinvestment of dividends will not relieve participants of any federal, state or local income tax, which may be due with respect to such dividend. Dividends reinvested in common shares will be treated on your federal income tax return as though you had received a dividend in cash in an amount equal to the fair market value of the shares received, as determined by the prices for common shares of the Fund on the NYSE as of the dividend payment date. Distributions from the Fund’s long-term capital gains will be processed as noted above for those electing to reinvest in common shares and will be taxable to you as long-term capital gains. The confirmation referred to above will contain all the information you will require for determining the cost basis of shares acquired and should be retained for that purpose. At year end, each account will be supplied with detailed information necessary to determine total tax liability for the calendar year.

All correspondence or additional information concerning the Plan should be directed to the Plan Agent, Mellon Bank, N.A., c/o Mellon Investor Services, P.O. Box 3338, South Hackensack, New Jersey 07606-1938 (Telephone: 1-800-852-0218).

Board Consideration of and
Continuation of Investment Advisory
Agreement and Subadvisory
Agreement: John Hancock Income
Securities Trust

The Investment Company Act of 1940 (the 1940 Act) requires the Board of Trustees (the Board) of John Hancock Income Securities Trust (the Fund), including a majority of the Trustees who have no direct or indirect interest in the investment advisory agreement and are not “interested persons” of the Fund, as defined in the 1940 Act (the Independent Trustees), annually to meet in person to review and consider the continuation of: (i) the investment advisory agreement (the Advisory Agreement) with John Hancock Advisers, LLC (the Adviser) and (ii) the investment subadvisory agreement (the Subadvisory Agreement) with MFC Global Investment Management (U.S.), LLC (the Subadviser). The Advisory Agreement and the Subadvisory Agreement are collectively referred to as the Advisory Agreements.

At meetings held on May 7 and June 4–5, 2007, the Board considered the factors and reached the conclusions described below relating to the selection of the Adviser and Subadviser and the continuation of the Advisory Agreements. During such meetings, the Board’s Contracts/ Operations Committee and the Independent Trustees also met in executive sessions with their independent legal counsel.

In evaluating the Advisory Agreements, the Board, including the Contracts/Operations Committee and the Independent Trustees, reviewed a broad range of information requested for this purpose by the Independent Trustees, including: (i) the investment performance of the Fund relative to a category of relevant funds (the Category) and a peer group of comparable funds (the Peer Group) each selected by Morningstar, Inc. (Morningstar), an independent provider of investment company data, for a range of periods ended December 31, 2006, (ii) advisory and other fees incurred by, and the expense ratios of, the Fund relative to a Category and a Peer Group, (iii) the advisory fees of comparable portfolios of other clients of the Adviser and the Subadviser, (iv) the Adviser’s financial results and condition, including its and certain of its affiliates’ profitability from services performed for the Fund, (v) breakpoints in the Fund’s and the Peer Group’s fees, and information about economies of scale, (vi) the Adviser’s and Subadviser’s record of compliance with applicable laws and regulations, with the Fund’s investment policies and restrictions, and with the applicable Code of Ethics, and the structure and responsibilities of the Adviser’s and Subadviser’s compliance department, (vii) the background and experience of senior management and investment professionals, and (viii) the nature, cost and character of advisory and non-investment management services provided by the Adviser and its affiliates and by the Subadviser.

The Independent Trustees considered the legal advice of independent legal counsel and relied on their own business judgment in determining the factors to be considered in evaluating the materials that were presented to them and the weight to be given to each such factor. The Board’s review and conclusions were based on a comprehensive consideration of all information presented to the Board and not the result of any single controlling factor. They principally considered performance and other information from Morningstar as of December 31, 2006. The Board also considered updated performance information provided to it by the Adviser or Subadviser at the May and June 2007 meetings. Performance and other information may be quite different as of the date of this shareholders report. The key factors considered by the Board and the conclusions reached are described below.

Nature, extent and quality of services

The Board considered the ability of the Adviser and the Subadviser, based on their resources, reputation and other attributes, to attract and retain qualified investment professionals, including research, advisory and supervisory personnel. The Board considered the investment philosophy, research and investment decision-making processes of the Adviser and Subadviser. The Board further considered the culture of compliance, resources dedicated to compliance, compliance programs and compliance records of the Adviser and Subadviser. In addition, the Board took into account the

Income Securities Trust | Annual report

administrative and other non-advisory services provided to the Fund by the Adviser and its affiliates.

Based on the above factors, together with those referenced below, the Board concluded that, within the context of its full deliberations, the nature, extent and quality of the investment advisory services provided to the Fund by the Adviser and Subadviser supported renewal of the Advisory Agreements.

Fund performance

The Board considered the performance results for the Fund over various time periods ended December 31, 2006. The Board also considered these results in comparison to the performance of the Category, as well as the Fund’s Peer Group and benchmark index. Morningstar determined the Category and Peer Group for the Fund. The Board reviewed with a representative of Morningstar the methodology used by Morningstar to select the funds in the Category and the Peer Group. The Board noted the imperfect comparability of the Peer Group.

The Board noted that the Fund’s performance was lower than the performance of the Category and Peer Group medians, but was higher than the performance of its benchmark index, the Lehman Brothers Government/ Credit Bond Index, over the 3-, 5- and 10- year periods. The Board noted that the Fund’s more recent performance during the 1-year period was lower than, but generally competitive with, the performance of the Category median, and higher than the performance of the Peer Group median and benchmark index. The Adviser noted that the Fund’s Peer Group contained primarily unleveraged closed-end funds, which had a high level of high-yield exposure. The Adviser explained that these factors impacted the Fund’s comparative performance results.

Investment advisory fee and subadvisory fee rates and expenses

The Board reviewed and considered the contractual investment advisory fee rate payable by the Fund to the Adviser for investment advisory services (the Advisory Agreement Rate). The Board received and considered information comparing the Advisory Agreement Rate with the advisory fees for the Category and Peer Group. The Board noted that the Advisory Agreement Rate was higher than the median rate of the Peer Group and Category.

The Board received and considered expense information regarding the Fund’s various components, including advisory fees, and other non-advisory fees, including transfer agent fees, custodian fees and other miscellaneous fees (e.g., fees for accounting and legal services). The Board considered comparisons of these expenses to the Peer Group median. The Board also received and considered expense information regarding the Fund’s total operating expense ratio (Expense Ratio). The Board noted that, unlike the Fund, several funds in the Peer Group employed fee waivers or reimbursements. The Board received and considered information comparing the Expense Ratio of the Fund to that of the Category and Peer Group medians before the application of fee waivers and reimbursements (Gross Expense Ratio) and after the application of such waivers and reimbursement (Net Expense Ratio). The Board noted that the Fund’s Expense Ratio was higher than the Gross and Net Expense Ratio of the Peer Group median. The Board also noted the differences in the funds included in the Peer Group, including differences in the employment of fee waivers and reimbursements and differences in the amount of assets under management. The Board noted that the Fund’s Expense Ratio was lower than the Gross Expense Ratio and equal to the Net Expense Ratio of the Category median.

The Adviser also discussed the Morningstar data and rankings, and other relevant information, for the Fund. The Adviser noted that most of the funds in the Peer Group were unleveraged, which contributed to the results. Based on the above-referenced considerations and other factors, the Board concluded that the Fund’s overall expense results and performance supported the re-approval of the Advisory Agreements.

The Board also received information about the investment subadvisory fee rate (the Subadvisory Agreement Rate) payable by the Adviser to the Subadviser for investment subadvisory services. The Board concluded

Annual report | Income Securities Trust

that the Subadvisory Agreement Rate was fair and equitable, based on its consideration of the factors described here.

Profitability

The Board received and considered a detailed profitability analysis of the Adviser based on the Advisory Agreements, as well as on other relationships between the Fund and the Adviser and its affiliates, including the Subadviser. The Board also considered a comparison of the Adviser’s profitability to that of other similar investment advisers whose profitability information is publicly available. The Board concluded that, in light of the costs of providing investment management and other services to the Fund, the profits and other ancillary benefits reported by the Adviser were not unreasonable.

Economies of scale

The Board received and considered general information regarding economies of scale with respect to the management of the Fund, including the Fund’s ability to appropriately benefit from economies of scale under the Fund’s fee structure. The Board recognized the inherent limitations of any analysis of economies of scale, stemming largely from the Board’s understanding that most of the Adviser’s and Subadviser’s costs are not specific to individual Funds, but rather are incurred across a variety of products and services.

The Board noted that the Advisory Agreements offered breakpoints. However, the Board considered the limited relevance of economies of scale in the context of a closed-end fund that, unlike an open-end fund, does not continuously offer its shares. The Board noted that the Fund, as a closed-end investment company, was not expected to increase materially in size and that its assets would grow (if at all) through the investment performance of the Fund. Therefore, the Board did not consider potential economies of scale as a principal factor in assessing the fees payable under the Advisory Agreements, but concluded that the fees were fair and equitable based on relevant factors.

Other benefits to the Adviser

The Board received information regarding potential “fall-out” or ancillary benefits received by the Adviser and its affiliates as a result of the Adviser’s relationship with the Fund. Such benefits could include, among others, benefits directly attributable to the relationship of the Adviser with the Fund and benefits potentially derived from an increase in the business of the Adviser as a result of its relationship with the Fund (such as the ability to market to shareholders other financial products offered by the Adviser and its affiliates).

The Board also considered the effectiveness of the Adviser’s, Subadviser’s and Fund’s policies and procedures for complying with the requirements of the federal securities laws, including those relating to best execution of portfolio transactions and brokerage allocation.

Other factors and broader review

As discussed above, the Board reviewed detailed materials received from the Adviser and Subadviser as part of the annual re-approval process. The Board also regularly reviews and assesses the quality of the services that the Fund receives throughout the year. In this regard, the Board reviews reports of the Adviser and Subadviser at least quarterly, which include, among other things, fund performance reports and compliance reports. In addition, the Board meets with portfolio managers and senior investment officers at various times throughout the year.

After considering the above-described factors and based on its deliberations and its evaluation of the information described above, the Board concluded that approval of the continuation of the Advisory Agreements for the Fund was in the best interest of the Fund and its shareholders. Accordingly, the Board unanimously approved the continuation of the Advisory Agreements.

Neither the Adviser or the Subadviser receives a fee based upon the investment performance of any of the accounts included under “Other Accounts Managed by the Portfolio Managers” in the table above.

When a portfolio manager is responsible for the management of more than one account, the potential arises for the portfolio manager to favor one account over another. For the reasons outlined below, the Fund does not believe that any material conflicts are likely to arise out of a portfolio manager’s responsibility for the management of the Fund as well as one or more other accounts. The Adviser and the Subadviser have adopted procedures, overseen by the Chief Compliance Officer, that are intended to monitor compliance with the policies referred to in the following paragraphs.

• The Subadviser has policies that require a portfolio manager to allocate investment opportunities in an equitable manner and generally to allocate such investments proportionately among all accounts with similar investment objectives.

• When a portfolio manager intends to trade the same security for more than one account, the policies of the Subadviser generally require that such trades for the individual accounts are aggregated so each account receives the same price. Where not possible or may not result in the best possible price, the Subadviser will place the order in a manner intended to result in as favorable a price as possible for such client.

• The investment performance on specific accounts is not a factor in determining the portfolio manager’s compensation. See “Compensation of Portfolio Managers” below. Neither the Adviser nor the Subadviser receives a performance-based fee with respect to other accounts managed by the Fund’s portfolio managers.

• The Subadviser imposes certain trading restrictions and reporting requirements for accounts in which a portfolio manager or certain family members have a personal interest in order to confirm that such accounts are not favored over other accounts.

• The Subadviser seeks to avoid portfolio manager assignments with potentially conflicting situations. However, where a portfolio manager is responsible for accounts with differing investment objectives and policies, it is possible that the portfolio manager will conclude that it is in the best interest of one account to sell a portfolio security while another account continues to hold or increase the holding in such security.

Compensation of Portfolio Managers

The Subadviser has adopted a system of compensation for portfolio managers and others involved in the investment process that is applied consistently among investment professionals. At the Subadviser, the structure of compensation of investment professionals is currently comprised of the following basic components: fixed base salary, and an annual investment bonus plan, as well as customary benefits that are offered generally to all full-time employees of the Subadviser. A limited number of senior investment professionals, who serve as officers of both the Subadviser and its parent company, may also receive options or restricted stock grants of common shares of Manulife Financial.

Income Securities Trust | Annual report

professional over one-, three- and five-year periods are considered. The pre-tax performance of each account is measured relative to an appropriate peer group benchmark. 2) The profitability of the Subadviser and its parent company are also considered in determining bonus awards, with greater emphasis placed upon the profitability of the Adviser. 3) The more intangible contributions of an investment professional to the Subadviser’s business, including the investment professional’s support of sales activities, new fund/strategy idea generation, professional growth and development, and management, where applicable, are evaluating in determining the amount of any bonus award.

While the profitability of the Subadviser and the investment performance of the accounts that the investment professionals maintain are factors in determining an investment professional’s overall compensation, the investment professional’s compensation is not linked directly to the net asset value of any fund.

ITEM 2. CODE OF ETHICS.

As of the end of the period, December 31, 2007, the registrant has adopted a code of ethics, as defined in Item 2 of Form N-CSR, that applies to its Chief Executive Officer, Chief Financial Officer and Treasurer (respectively, the principal executive officer, the principal financial officer and the principal accounting officer, the “Senior Financial Officers”). A copy of the code of ethics is filed as an exhibit to this Form N-CSR.

ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

Charles L. Ladner is the audit committee financial expert and is “independent”, pursuant to general instructions on Form N-CSR Item 3.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

(a) Audit Fees

The aggregate fees billed for professional services rendered by the principal accountant(s) for the audit of the registrant’s annual financial statements or services that are normally provided by the accountant(s) in connection with statutory and regulatory filings or engagements amounted to $26,250 for the fiscal year ended December 31, 2007 and $26,250 for the fiscal year ended December 31, 2006. These fees were billed to the registrant and were approved by the registrant’s audit committee.

(b) Audit-Related Services

There were no audit-related fees during the fiscal year ended December 31, 2007 and fiscal year ended December 31, 2006 billed to the registrant or to the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant ("control affiliates").

The aggregate fees billed for professional services rendered by the principal accountant(s) for the tax compliance, tax advice and tax planning (“tax fees”) amounted to $3,500 for the fiscal year ended December 31, 2007 and $3,500 for the fiscal year ended December 31, 2006. The nature of the services comprising the tax fees was the review of the registrant’s income tax returns and tax distribution requirements. These fees were billed to the registrant and were approved by the registrant’s audit committee. There were no tax fees billed to the control affiliates.

(d) All Other Fees

The all other fees billed to the registrant for products and services provided by the principal accountant were $3,000 for the fiscal year ended December 31, 2007 and $3,000 for the fiscal year ended December 31, 2006. There were no other fees during the fiscal year ended December 31, 2007 and December 31, 2006 billed to control affiliates for products and services provided by the principal accountant. The nature of the services comprising the all other fees was related to the principal accountant’s report on the registrant’s Eligible Asset Coverage. These fees were approved by the registrant’s audit committee.

(e)(1) Audit Committee Pre-Approval Policies and Procedures:

The trust’s Audit Committee must pre-approve all audit and non-audit services provided by the independent registered public accounting firm (the “Auditor”) relating to the operations or financial reporting of the funds. Prior to the commencement of any audit or non-audit services to a fund, the Audit Committee reviews the services to determine whether they are appropriate and permissible under applicable law.

The trust’s Audit Committee has adopted policies and procedures to, among other purposes, provide a framework for the Committee’s consideration of audit-related and non-audit services by the Auditor. The policies and procedures require that any audit-related and non-audit service provided by the Auditor and any non-audit service provided by the Auditor to a fund service provider that relates directly to the operations and financial reporting of a fund are subject to approval by the Audit Committee before such service is provided. Audit-related services provided by the Auditor that are expected to exceed $50,000 per year/per fund are subject to specific pre-approval by the Audit Committee. Tax services provided by the Auditor that are expected to exceed $50,000 per year/per fund are subject to specific pre-approval by the Audit Committee. Other services provided by the Auditor that are expected to exceed $10,000 per year/per fund are subject to specific pre-approval by the Audit Committee.

All audit services, as well as the audit-related and non-audit services that are expected to exceed the amounts stated above, must be approved in advance of provision of the service by formal resolution of the Audit Committee. At the regularly scheduled Audit Committee meetings, the Committee reviews a report summarizing the services, including fees, provided by the Auditor.

(e)(2) Services approved pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X:

Audit-Related Fees, Tax Fees and All Other Fees:
There were no amounts that were approved by the Audit Committee pursuant to the de minimis exception under Rule 2-01 of Regulation S-X.

(f) According to the registrant’s principal accountant, for the fiscal year ended December 31, 2007, the percentage of hours spent on the audit of the registrant's financial statements for the most recent fiscal year that were attributed to work performed by persons who were not full-time, permanent employees of principal accountant was less than 50%.

(g) The aggregate non-audit fees billed by the registrant's accountant(s) for services rendered to the registrant and rendered to the registrant's control affiliates for each of the last two fiscal years of the registrant were $1,553,823 for the fiscal year ended December 31, 2007, and $872,192 for the fiscal year ended December 31, 2006.

(h) The audit committee of the registrant has considered the non-audit services provided by the registrant’s principal accountant(s) to the control affiliates and has determined that the services that were not pre-approved are compatible with maintaining the principal accountant(s)' independence.
