CEO corner

To Our Shareholders,

The stock market gained ground in the first half of 2007, returning 6.96% through June 30, as measured by the Standard & Poor’s 500 Index. It was bolstered by stronger-than-expected corporate earnings growth, healthy global economic growth, increased merger and acquisitions activity and mostly steady interest rates. These positives served to overcome concerns about inflation, a slumping housing market, the subprime mortgage debacle and mixed signals on the future direction of interest rates.

In fact, at the end of May, the stock market passed a significant milestone, when the broad Standard & Poor’s 500 Index climbed beyond the record it had set seven years ago. From its peak in March 2000, the stock market spiraled downward three consecutive years, bottoming in 2002. The upturn began in 2003, and the market has advanced each year since, finally setting a new high on May 30, 2007.

This nearly complete market cycle highlights the importance of an investment principle you have heard us speak of often: diversification. That is because it is a key to protecting, and growing, your assets. By allocating your investments among different asset classes, investment styles and portfolio managers, you are likely to be well represented through all phases of a complete market cycle, with the winners helping to cushion the fall of the losers.

The challenge for investors with a diversified portfolio is to properly evaluate your investments to tell the difference between an underperforming manager and an out-of-favor style, while also understanding the role each investment plays in your portfolio. That’s where your financial professional can provide true value. He or she can help you make those assessments and also counsel patience, because a properly diversified portfolio by its very nature will typically have something lagging or out of favor — a concept that can be difficult to live with, but necessary to embrace. If everything in your portfolio is “working,” then you are not truly diversified, but rather are leveraged to the current market and the flavor of the day. If so, you are bound to be out of step in the near future.

With the recent volatility in the securities markets, it has prompted investors to question how long this type of market cycle will last. History tells us it will end and that when it does, today’s leaders may well turn into laggards and vice versa. Indeed, the current subprime mortgage market woes, the subsequent credit crunch and their impact on the financial markets and the global credit markets, are just the latest examples of why investors should be well-diversified. For with patience and a diversified portfolio, it could be easier to weather the market’s twists and turns and reach your long-term goals.

Sincerely,

Keith F. Hartstein,
President and Chief Executive Officer

Managers’ report

John Hancock

Income Securities Trust

In an environment of rising interest rates, U.S. bonds produced modestly positive returns in the first half of 2007. The Lehman Brothers Aggregate Bond Index, a broad measure of bond market performance, returned 0.98% for the six-month period.

Bonds gained ground in the first quarter of the year as the U.S. economy continued to weaken, producing an annualized growth rate of just 0.7% . A continued slump in the housing market led to worsening delinquencies and foreclosures among subprime borrowers, and the resulting “flight to quality” helped boost the bond market.

In the second quarter, however, economic data came in stronger than expected, most notably in the labor market. In addition, inflation remained persistently above trend, in part because of a renewed rise in energy prices. As a result, expectations of an interest rate cut by the Federal Reserve before year-end faded. This combination of factors led to rising interest rates in the last two months of the period, erasing most of the bond market’s earlier gains.

The yield curve grew steeper during the six-month period. At the start of the year, the yield curve was “inverted” — short-term bond yields were slightly higher than the yields of longer-term bonds. However, longer-term bond yields rose higher than short-term yields during the period, and the yield curve returned to a more “normal” shape.

Every sector of the bond market gained ground during the period. High-yield corporate bonds remained the top performers, though rising interest rates and a significant increase in new issues led to a sharp pullback in the high yield market late in the period. Among investment-grade sectors, mortgage-backed securities posted the best returns, while corporate bonds lagged.

“In an environment of rising

produced modestly positive
returns in the first half of 2007.”

Fund performance

For the six months ended June 30, 2007, John Hancock Income Securities Trust produced a total return of 1.14% at net asset value (NAV) and –1.45% 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. The Fund’s yield at closing market price on June 30, 2007 was 6.53% . By comparison, the average closed-end intermediate-term bond fund returned 1.92%, according to Morningstar, Inc., and the Lehman Brothers Government/Credit Bond Index returned 0.97% .

Overweight positions in high-yield corporate bonds and mortgage-backed securities helped the portfolio outperform its benchmark index, but our Morningstar peer group has an even higher average weighting in high-yield bonds, and that factor contributed to our underperformance of the peer group average.

High yield added value

The portfolio’s outperformance of its benchmark index was driven in part by our position in high-yield corporate bonds, which outperformed during the six-month period. Although we reduced our overall exposure

Income Securities Trust

to corporate bonds during the period, we mainly sold investment-grade corporate securities and maintained our weighting in lower-quality corporate bonds.

We cut back on our investment-grade holdings because of concerns about “event risk” — leveraged buyouts, special dividends and other actions that favor stockholders over bondholders. In contrast, event risk has little impact on the lower-quality segment of the market, where companies are typically too debt-heavy to take on additional borrowing. Another factor in favor of high yield bonds was the positive fundamental backdrop — solid balance sheets, healthy corporate earnings growth and very few defaults.

Many of the top-performing bonds in the portfolio were high yield securities. The best contributor was Cinemark, Inc., which owns a chain of movie theaters. The CCC-rated bonds rallied as business conditions improved, the summer movie season appeared promising and the company successfully reduced its debt load. Another strong performer was shipping company Navios Maritime Holdings, Inc., which benefited from the strength of global trade. Toward the end of the period, we sold some high yield bonds that had enjoyed a strong run-up, including car rental company Avis, clothing maker Hanes Brands and food services provider Aramark.

The weakest performers among corporate securities tended to be longer-term bonds that suffer greater price declines when interest rates rise. An example was a bond issued by Liberty Mutual Group, a property and casualty insurer, that matures in 2036. The combination of a long maturity and general weakness among finance-related companies because of the subprime lending problems weighed on this bond.

Upgrading mortgage holdings

We modestly increased our position in mortgage-backed securities, the largest sector weighting in the portfolio, which provided a boost to performance during the period. Within the mortgage segment, we improved the credit quality of our holdings by increasing our exposure to mortgage-backed securities issued by government agencies. We also added

Income Securities Trust

a small position in interest-only bonds, which represent ownership in the interest payments of a pool of mortgages. These securities typically increase in value when the housing market weakens and mortgage prepayment activity declines, as it has in recent months.

“Overweight positions in high-
yield corporate bonds and
mortgage-backed securities
helped the portfolio outperform
its benchmark index…”

Benefiting from the steeper yield curve

The steeper yield curve during the period also boosted Fund performance modestly. We positioned the portfolio to benefit from this steeper environment by reducing exposure to short- and long-term securities and shifting these assets into the intermediate sector of the market, with maturities ranging from seven to 10 years. We expect the yield curve to grow steeper going forward and plan to maintain this positioning.

Outlook

Recent signs of resilience in the U.S. economy are likely to keep the Fed on hold through the end of the year. Nonetheless, we expect the housing market to weaken further, which should keep economic growth at a below-trend rate in the second half of 2007. We intend to remain overweight in mortgage-backed securities, though we are positioned defensively within the mortgage sector, and we believe corporate bonds can continue to outperform in a relatively stable credit environment.

Notes to financial statements (unaudited)

Note 1
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 (the 1940 Act).

Significant accounting policies of the Fund
are as follows:

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. All other securities held by the Fund are valued at the last sale price or official closing price (closing bid price or last evaluated quote if no sale has occurred) as of the close of business on the principal securities exchange (domestic or foreign) on which they trade or, lacking any sales, at the closing bid price. Securities traded only in the over-the-counter market are valued at the last bid price quoted by brokers making markets in the securities at the close of trading. Securities for which there are no such quotations, principally debt securities, are valued based on the valuation provided by an independent pricing service, which utilizes both dealer-supplied and electronic data processing techniques, which take into account factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics and other market data.

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

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. 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

Income Securities Trust

delivered to the Fund at a future date, usually beyond customary settlement date.

Discount and premium on securities

The Fund utilizes the level yield method to accrete discount 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 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 in amounts up to 33¹/₃% of the Fund’s total assets. Such loans are callable at any time and are at all times fully secured by cash, cash equivalents or securities issued or guaranteed by the U.S. government or its agencies or instrumentalities and marked-to-market on a daily basis. The Fund may bear the risk of delay in recovery of, or even of rights in, the securities loaned should the borrower of the securities fail financially.

The Fund receives compensation for lending their securities either in the form of fees and/or by retaining a portion of interest on the investment of any cash received as collateral. The Fund invests the cash collateral received in connection with securities lending transactions in JHCIT, a Delaware common law trust and an affili-ated fund. JHCIT is exempt from registration under Section 3(c)(7) of the 1940 Act (pursuant to exemptive order issued by the SEC) and is managed by the Adviser, for which the Adviser receives an investment advisory fee of 0.04% of the average daily net assets of the JHCIT.

All collateral received will be in an amount equal to at least 100% of the market value of the loaned securities and is intended to be maintained at that level 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 the next business day. During the loan period, the Fund continues to retain rights of ownership, including dividends and interest of the loaned securities. As of June 30, 2007, the Fund loaned securities having a market value of $8,607,915 collateralized by cash invested in securities in the amount of $8,550,490.

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. Initial margin deposits required upon entering into futures contracts are satisfied by the segregation of specific securities or cash as collateral for the account of the broker (the Funds’ agent in acquiring futures position). 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 gain s 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, 2007, the Fund had deposited $130,900 in a segregated account for the broker to cover margin requirements on open financial futures contracts.

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 $7,909,723 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, 2012 — $2,123,466, December 31, 2013 — $2,443,482 and December 31, 2014 — $3,342,775.

New accounting pronouncements

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 evaluated the application of this Interpretation to the Fund and does not believe there is a material impact resulting from the adoption of this Interpretation on the Fund’s financial statements.

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 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 investment income by ceasing current accruals or writing off interest receivable when the collection of income 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, 2006, the tax character of distributions paid was as follows: ordinary income $14,667,522.

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 2
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 Fund has an agreement with the Adviser and affiliates to perform necessary tax, accounting and legal services for the Fund. The compensation for the period amounted to $17,505. The Fund also reimbursed John Hancock Life Insurance Company (JHLICO), a subsidiary of MFC, 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 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 SEC the certification of its chief executive officer and chief financial officer required by Section 302 of the Sarbanes-Oxley Act.

Note 3
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. However, based on experience, the Fund believes the risk of loss to be remote.

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 seven days thereafter by an auction. Dividend rates on APS Series A ranged from 5.00% to 5.30% and Series B from 4.94% to 5.31% during the period ended June 30, 2007. 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. 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. The Fund generally will not issue preferred shares unless the Adviser expects that the Fund will achieve a greater return on the proceeds resulting from the use of leverage than the additional costs the Fund incurs as a result of leverage. 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. The Board of Trustees will monitor this potential conflict. The Fund’s use of leverage is premised upon the expectation that the

Income Securities Trust

Fund’s dividends on its outstanding preferred shares will be lower than the return the Fund achieves on its investments with the proceeds of the issuance of preferred shares.

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.

Note 5
Investment transactions

Purchases and proceeds from sales or maturities of securities, other than short-term securities and obligations of the U.S. government, during the period ended June 30, 2007, aggregated $83,987,688 and $78,016,609, respectively. Purchases and proceeds from sales or maturities of obligations of the U.S. government aggregated $8,584,459 and $12,026,065, respectively, during the period ended June 30, 2007.

The cost of investments owned on June 30, 2007, including short-term investments, for federal income tax purposes was $273,126,155. Gross unrealized appreciation and depreciation of investments aggregated $1,721,884 and $4,923,264, respectively, resulting in net unrealized depreciation of $3,201,380.

Income Securities Trust

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 shareholde rs. 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.

Income Securities Trust

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 $0.4525 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

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 mea n 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

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).

Income Securities Trust

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

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 hi gher 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

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.
