To Our Shareholders,

After producing modest returns in 2005, the stock market advanced smartly in the first four months of 2006. Investors were encouraged by solid corporate earnings, a healthy economy and stable inflation, which suggested the Federal Reserve could be coming close to the end of its two-year campaign of raising interest rates. Those hopes were dashed in May, however, when economic data suggested a resurgence of inflation and more Fed rate hikes. The result was a significant increase in volatility and a market pull-back that continued into June, erasing much of the earlier gains. For the first six months of 2006, the market advanced slightly, returning 2.71%, as measured by the Standard & Poor’s 500 Index. Inflation and rate hike concerns also worked on the bond market, which, with the exception of low-quality bonds, lost a bit of ground over the last six months.

With the financial markets’ about-face and increased volatility, it is anyone’s guess where the market will end 2006, especially given the wild cards of interest rate moves and record-high energy prices and their impact on the economy and corporate profits.

One thing we do know, however, is that the stock market’s pattern is one of extremes. Consider the last 10 years. From 1995 through 1999, we saw double-digit returns in excess of 20% per year, only to have 2000 through 2002 produce ever-increasing negative results, followed by another 20%-plus up year in 2004 and a less than 5% advance in 2005. Since 1926, the market, as measured by the Standard & Poor’s 500 Index, has produced average annual results of 10.4% . However, that “normal” return is rarely produced in any given year. In fact, calendar-year returns of 8% to 12% have occurred only five times in the 80 years since 1926.

Although the past in no way predicts the future, we have learned at least one lesson from history: Expect highs and lows in the short term, but always invest for the long term. Equally important: Work with your financial professional to maintain a diversified portfolio, spread out among not only different asset classes — stocks, bonds and cash — but also among various investment styles. It’s the best way we know of to benefit from, and weather, the market’s extremes.

Sincerely,

Keith F. Hartstein,
President and Chief Executive Officer

MANAGERS’
REPORT

JOHN HANCOCK

Income Securities Trust

Rising interest rates — resulting from a robust economy and higher inflation — led to modestly negative returns for bonds in the first six months of 2006. The Lehman Brothers U.S. Aggregate Bond Index, a broad measure of bond market performance, returned –0.72% .

“Rising interest rates — resulting
from a robust economy and
higher inflation — led to mod-
estly negative returns for bonds
in the first six months of 2006.”

The U.S. economy grew at a healthy 5.6% annual rate in the first quarter of 2006, rebounding from a hurricane-related slowdown in late 2005, and growth continued at a solid, though slower, rate in the second quarter. Inflation concerns also surfaced as the consumer price index surged at an annual rate of nearly 5% in the first half of the year. Noting the elevated inflation levels, the Federal Reserve raised short-term interest rates four times during the six-month period, for a total of 17 rate hikes in the past two years. By June 30, the federal funds rate stood at 5.25%, its highest level in more than five years.

In this environment, interest rates rose in parallel fashion; Treasury bond yields climbed by about three-quarters of a percentage point across the maturity spectrum. As a result, the yield curve remained flat, meaning short- and long-term bond yields were roughly equal.

Sector performance was mixed but generally negative. Treasury bonds, which are most sensitive to interest rate fluctuations, and investment-grade corporate bonds posted the biggest declines. Mortgage-backed securities and government agency bonds were largely unchanged during the period, while high-yield corporate bonds gained ground, bucking the downward trend.

Fund performance

For the six months ended June 30, 2006, John Hancock Income Securities Trust produced a total return of -0.27% at net asset value (NAV) and 0.19% 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 0.04%, according to Morningstar, Inc., and the Lehman Brothers Government/Credit Bond Index returned –1.15% .

Shifting into neutral

Over the past two years, the Fund has been positioned defensively to guard against rising interest rates and widening risk premiums. We lowered the portfolio’s interest rate sensitivity, improved its overall credit quality and adjusted the maturity structure to benefit from a convergence of short- and long-term bond yields.

During the past six months, however, we have been scaling back our defensive approach and moving toward a more neutral position with regard to interest rate sensitivity and maturity structure. With the yield convergence largely played out, we began to position the Fund for the inevitable widening of short- and long-term yields.

Focusing on mortgages

One pillar of our defensive strategy that remained in place during the six-month period was upgrading the portfolio’s credit quality. Toward that end, we significantly increased our holdings of mortgage-backed securities. By the end of the period, mortgage-backed bonds comprised the largest sector weighting in the portfolio. In addition to improving portfolio credit quality, mortgage-backed securities offered more attractive yields than many investment-grade corporate bonds of comparable maturity.

“The best performers in the portfo-
lio in the first half of 2006 were
airline bonds, which benefited from
increased air traffic and improving
operating results.”

Within the mortgage-backed segment, we emphasized commercial mortgages and adjustable-rate mortgages, which offered competitive yields and less interest rate sensitivity than conventional fixed-rate residential mortgages. This positioning generally proved favorable as these types of mortgage-backed securities outperformed during the period.

Reducing corporate exposure

To accommodate the increase in mortgage-related securities, we reduced our holdings of corporate bonds, primarily by becoming

more selective in our investment-grade holdings. With the housing market starting to cool off and consumer spending expected to slow, we limited our exposure to bonds issued by consumer-oriented companies, automakers and homebuilders.

We also remained wary of companies under pressure from equity investors to reduce cash and/or take on more debt to boost stockholder returns, because these moves generally weaken a company’s financial position. Instead, we focused on securities issued by utilities, banks and finance-related companies, which are typically unwilling or unable to compromise their balance sheets and credit ratings.

At the margins, we increased our position in high yield corporate bonds, but this was driven by specific securities that we found to be attractively valued rather than any broad tactical strategy.

Leaders and laggards

The best performers in the portfolio in the first half of 2006 were airline bonds, which benefited from increased air traffic and improving operating results. In particular, bonds backed by Continental Airlines, Inc. jets were the top individual contributors to performance.

Our modest position in Ford Motor Credit Co., the automaker’s financing arm, also enhanced results during the period. The bonds declined sharply in 2005 after the company suffered sizable losses and a credit-rating downgrade, but the sell-off was overdone and these securities rebounded in 2006.

The weakest performers tended to be longer-term bonds, which declined the most as interest rates rose. The portfolio’s emerging-market holdings also fell as a shift toward risk aversion late in the period put downward pressure on these markets. Examples from the portfolio include bonds issued by Telefonos de Mexico, the largest telecom company in Mexico, and Latin American wireless services provider America Movil SA de CV.

“If the Fed holds rates steady, we
expect the bond market to be rela-
tively stable as well, which means
performance will be driven largely
by interest payments.”

Outlook

After two years of steady rate hikes, the Fed is likely nearing the end of its short-term interest rate increases. We are already seeing some evidence of slowing economic activity, especially in the job market, but the Fed’s focus is squarely on the inflation rate. Any further Fed rate hikes will be dependent on inflation readings in the coming months. If the Fed holds rates steady, we expect the bond market to be relatively stable as well, which means performance will be driven largely by interest payments.

Within the portfolio, we will continue to favor mortgage-backed securities over investment-grade corporate bonds because they offer more attractive yields, higher credit quality and better downside protection.

Notes to Financial Highlights

¹Audited by previous auditor.

²As required, effective 1-1-01, the Fund has adopted the provisions of the AICPA Audit and Accounting Guide for Investment Companies, as revised, relating to the amortization of premiums and accretion of discounts on debt securities. The effect of this change on per share amounts for the year ended 12-31-01, was to decrease net investment income per share by $ 0.02, increase net realized and unrealized gain per share by $0.02 and, had the Fund not made these changes to amortization and accretion, the annualized ratio of net investment income to average net assets would have been 6.30% . Per share ratios and supplemental data for periods prior to 1-1-01, have not been restated to reflect this change in presentation.

³Semiannual period from 1-1-06 through 6-30-06. Unaudited.

⁴Based on the average of the shares outstanding.

⁵APS Series A and B were issued on 11-4-03.

⁶Assumes dividend reinvestment.

⁷Not annualized.

⁸Ratios 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% and 0.78% for the periods ended 12-31-03, 12-31-04, 12-31-05 and 6-30-06, respectively.

⁹Annualized.

¹⁰Ratios 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% and 5.61% for the periods ended 12-31-03, 12-31-04, 12-31-05 and 6-30-06, respectively.

¹¹Calculated 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.

NOTES TO
STATEMENTS

Unaudited

Note A
Accounting policies

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.

Significant accounting policies
of the Fund are as follows:

Valuation of investments

Securities in the Fund’s portfolio are valued on the basis of market quotations, valuations provided by independent pricing services or, if quotations are not readily available, or the value has been materially affected by events occurring after the closing of a foreign market, at fair value as determined in good faith in accordance with procedures approved by the Trustees. Short-term debt investments which have a remaining maturity of 60 days or less may be valued at amortized cost, which approximates market value. The Fund determines the net asset value of the common shares each business day.

Joint repurchase agreement

Pursuant to an exemptive order issued by the Securities and Exchange Commission, the Fund, along with other registered investment companies having a management contract with John Hancock Advisers, LLC (the “Adviser”), a wholly owned subsidiary of John Hancock Financial Services, Inc., a subsidiary of Manulife Financial Corporation (“MFC”), 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. The Adviser is responsible for ensuring that the agreement is fully collateralized at all times.

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 transactions are reported on trade date. Net realized gains and losses on sales of investments are determined on the identified cost basis. Some securities may be purchased on a “when-issued” or “forward commitment” basis, which means that the securities will be delivered to the Fund at a future date, usually beyond customary settlement date.

Discount and premium
on securities

The Fund accretes discount and amortizes premium from par value on securities from either the date of issue or the date of purchase over the life of the security.

Expenses

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

and type of expense and the relative sizes of the funds.

Securities lending

The Fund may lend securities to certain qualified brokers who pay the Fund negotiated lender fees. The loans are collateralized at all times with cash or securities with a market value at least equal to the market value of the securities on loan. As with other extensions of credit, the Fund may bear the risk of delay of the loaned securities in recovery or even loss of rights in the collateral, should the borrower of the securities fail financially. At June 30, 2006, the Fund loaned securities having a market value of $14,878,372 collateralized by securities in the amount of $15,282,236. Securities lending expenses are paid by the Fund to the Adviser.

Financial futures contracts

The Fund may buy and sell financial futures contracts. Buying futures tends to increase the Fund’s exposure to the underlying instrument. Selling futures tends to decrease the Fund’s exposure to the underlying instrument or hedge other Fund’s instruments. At the time the Fund enters into financial futures contracts, it is required to deposit with its custodian a specified amount of cash or U.S. government securities, known as “initial margin,” equal to a certain percentage of the value of the financial futures contract being traded. Each day, the futures contract is valued at the official settlement price of the board of trade or U.S. commodities exchange on which it trades. Subsequent payments to and from the broker, known as “variation margin,” are made on a daily basis as the market price of the financial futures contract fluctuates. Daily variation margin adjustments arising from this “mark to market” are recorded by the Fund as unrealized gains or losses.

When the contracts are closed, the Fund recognizes a gain or loss. Risks of entering into financial futures contracts include the possibility that there may be an illiquid market and/or that a change in the value of the contracts may not correlate with changes in the value of the underlying securities. In addition, the Fund could be prevented from opening or realizing the benefits of closing out financial futures positions because of position limits or limits on daily price fluctuation imposed by an exchange.

For federal income tax purposes, the amount, character and timing of the Fund’s gains and/or losses can be affected as a result of financial futures contracts.

On June 30, 2006, the Fund had deposited $269,750 in a segregated account to cover margin requirements on open financial futures contracts.

The Fund had the following financial futures contracts open on June 30, 2006:

	NUMBER OF
OPEN CONTRACTS	CONTRACTS	POSITION	EXPIRATION	APPRECIATION

U.S. 10-Year Treasury Note	415	Short	Sept 06	$282,405

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, the Fund has $2,123,466 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 carryforward expires as follows: December 31, 2013 —$2,123,466.

In June 2006, Financial Accounting Standards Board (FASB) Interpretation No. 48, Accounting for Uncertainty

in Income Taxes (the “Interpretation”) was issued, and is effective for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. This Interpretation 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, and requires certain expanded disclosures. Management has recently begun to evaluate the application of the Interpretation to the Fund, and has not at this time quantified the impact, if any, resulting from the adoption of this Interpretation on the Fund’s financial statements.

Dividends, interest and distributions

Dividend income on investment securities is recorded on the ex-dividend date or, in the case of some foreign securities, on the date thereafter when the Fund identifies the dividend. Interest income on investment securities is recorded on the accrual basis. The Fund may place a security on non-accrual status and reduce related interest income by ceasing current accruals and writing off interest receivables when the collection of interest has become doubtful. Foreign income may be subject to foreign withholding taxes, which are accrued as applicable.

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, 2005, the tax character of distributions paid was as follows: ordinary income $14,334,991.

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

Use of estimates

The preparation of these financial statements, in accordance with accounting principles generally accepted in the United States of America, incorporates estimates made by management in determining the reported amount of assets, liabilities, revenues and expenses of the Fund. Actual results could differ from these estimates.

Note B
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.

Effective December 31, 2005, the investment management teams of the Adviser were reorganized into Sovereign Asset Management LLC (“Sovereign”), a wholly owned indirect subsidiary of John Hancock Life Insurance Company (“JHLICo”), a subsidiary of MFC. The Adviser remains the principal advisor on the Fund and Sovereign acts as subadviser under the supervision of the Adviser. The restructuring did not have an impact on the Fund, which continues to be managed using the same investment philosophy and process. The Fund is not responsible for payment of the subadvisory fees.

The Fund has an agreement with the Adviser to perform necessary tax, accounting and legal services for the Fund. The compensation for the period amounted to $19,373. The Fund also paid the Adviser the amount of $100 for certain publishing services, included in the printing fees. The Fund also

reimbursed JHLICo for certain compliance costs, included in the Fund’s Statement of Operations.

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.

The Fund is listed for trading on the New York Stock Exchange (“NYSE”) and has filed with the NYSE its chief executive officer certification regarding compliance with the NYSE’s listing standards. The Fund also files with the Securities and Exchange Commission the certification of its chief executive officer and chief financial officer required by Section 302 of the Sarbanes-Oxley Act.

¹Semiannual period from 1-1-06 through 6-30-06. Unaudited.

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.

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 7 days thereafter by an auction. Dividend rates on APS Series A ranged from 3.95% to 5.26% and Series B from 4.00% to 5.25% during the

period ended June 30, 2006. Accrued dividends on APS are included in the value of APS on the Fund’s Statement of Assets and Liabilities.

The APS are redeemable at the option of the Fund, at a redemption price equal to $25,000 per share, plus accumulated and unpaid dividends on any dividend payment date. The APS are also 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. 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.

Purchases and proceeds from sales or maturities of obligations of U.S. government aggregated $21,726,821 and $41,519,470, respectively, during the period ended June 30, 2006.

The cost of investments owned on June 30, 2006, including short-term investments, for federal income tax purposes was $260,005,281. Gross unrealized appreciation and depreciation of investments aggregated $816,835 and $8,307,533, respectively, resulting in net unrealized depreciation of $7,490,698. The difference between book basis and tax basis net unrealized depreciation of investments is attributable primarily to the amortization of premiums on debt securities.

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.

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, 2006, dividends from net investment income totaling $0.4725 per share were paid to shareholders. The dates of payments and the amounts per share are as follows:

	INCOME
PAYMENT DATE	DIVIDEND

March 31, 2006	$0.2450
June 30, 2006	0.2275

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 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 Sub-Advisory
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 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 sub-advisory agreement (the “Sub-Advisory Agreement”) with Sovereign Asset Management LLC (the “Sub-Adviser”). The Advisory Agreement and the Sub-Advisory Agreement are collectively referred to as the “Advisory Agreements.”

At meetings held on May 1–2 and June 5–6, 2006,¹the Board considered the factors and reached the conclusions described below relating to the selection of the Adviser and Sub-Adviser 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, 2005, (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 Sub-Adviser, (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 Sub-Adviser’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 Sub-Adviser’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 Sub-Adviser.

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. It was based on performance and other information as of December 31, 2005; facts may have changed between that date and 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 Sub-Adviser, based on their resources, reputation and other attributes, to attract and retain qualified investment professionals, including research, advisory, and supervisory personnel. The Board further considered the compliance programs and compliance records of the Adviser and Sub-Adviser. In addition, the Board took into

account the administrative 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 Sub-Adviser were sufficient to support renewal of the Advisory Agreements.

Fund performance

The Board considered the performance results for the Fund over various time periods ended December 31, 2005. 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 Fund’s performance was lower than the performance of the Category and Peer Group medians and its benchmark index, the Lehman Brothers Aggregate Bond Index, over the 1- and 10- year periods. The Board also noted that the Fund’s performance for the 3- and 5- year periods was lower than the median performance of its Category and Peer Group, but higher than its benchmark index. The Board indicated its intent to continue to monitor the Fund’s performance trends.

Investment advisory fee and sub-advisory 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 equal to the median rate of the 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 received and considered information comparing the Expense Ratio of the Fund to that of the Category and Peer Group medians. The Board noted that the Fund’s Expense Ratio was not appreciably higher than the Category and Peer Group medians.

The Adviser also discussed the Morningstar data and rankings, and other relevant information, for the Fund. 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 sub-advisory fee rate (the “Sub-Advisory Agreement Rate”) payable by the Adviser to the Sub-Adviser for investment sub-advisory services. The Board concluded that the Sub-Advisory 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 Sub-Adviser. 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 Sub-Adviser’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 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 finan-cial products offered by the Adviser and its affiliates).

The Board also considered the effectiveness of the Adviser’s, Sub-Adviser’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 Sub-Adviser 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 Sub-Adviser 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.

¹The Board previously considered information about the Sub-Advisory Agreement at the September and December 2005 Board meetings in connection with the Adviser’s reorganization.
