Footnotes to Schedule of Investments

March 31, 2005 (unaudited)

(A) Credit ratings are unaudited and are rated by Moody's Investors
    Service where Standard & Poor's ratings are not available unless
    indicated otherwise.

(B) This security is fair valued in good faith under procedures
    established by the Board of Trustees.

(G) Security rated internally by John Hancock Advisers, LLC.

(H) Non-income-producing issuer filed for protection under the Federal
    Bankruptcy Code or is in default of interest payment.

(L) All or a portion of this security is on loan as of March 31, 2005.

(M) A portion of this security having an aggregate value of $460,575,
    or 0.18% of the Fund's total investments, has been purchased as a
    forward commitment--that is, the Fund has agreed on trade date to take
    delivery of and to make payment for this security on a delayed basis
    subsequent to the date of this schedule. The purchase price and
    interest rate of this security is fixed at trade date, although the
    Fund does not earn any interest on these until settlement date. The
    fund has segregated assets with a current value at least equal to the
    amount of the forward commitments. Accordingly, the market value of
    $480,536 of Federal National Mortgage Assn., 6.000%, 01-01-34 has been
    segregated to cover the forward commitment.

(N) These securities having an aggregate value of $5,543,629 or 2.11%
    of the Fund's total investments, have been purchased on a when-issued
    basis. The purchase price and the interest rate of such securities are
    fixed at trade date, although the Fund does not earn any interest on
    such securities until settlement date. The Fund has instructed its
    custodian bank to segregate assets with a current value at least equal
    to the amount of its when-issued commitments. Accordingly, the market
    value of $5,684,639 of Federal National Mortgage Assn., 6.000%,
    01-01-34 has been segregated to cover the when-issued commitments.

(O) Cash interest will be paid on this obligation at the stated rate
    beginning on the stated date.

(S) These securities are exempt from registration under Rule 144A of
    the Securities Act of 1933. Such securities may be resold, normally to
    qualified institutional buyers, in transactions exempt from
    registration. Rule 144A securities amounted to $29,453,139 or 11.20%
    of the Fund's total investments as of March 31, 2005.

    The percentage shown for each investment category is the total value
    of that category as a percentage of the total investments of the Fund.

    The cost of investments owned on March 31, 2005, including short-term
    investments, was $263,191,039. Gross unrealized appreciation and
    depreciation of investments aggregated $4,589,862 and $4,865,111,
    respectively, resulting in net unrealized depreciation of $275,249.
