(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 September 30, 2005.

(M) This security having an aggregate value of $3,280,784, or 1.26% 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 securitiy 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 this until settlement date. The fund has segregated assets with a current value at least equal to the amount of the forward commitment.

Accordingly, the market value of $3,366,065 of Federal National Mortgage Assn., 6.000%, 5-1-35 has been segregated to cover the forward commitment.

(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 $28,475,434 or 10.97% of the Fund's total investments as of September 30, 2005.

Parenthetical disclosure of a foreign country in the security description represents country of a foreign issuer; however, security is U.S. dollar-denominated.

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 September 30, 2005, including short-term investments, was $260,551,697. Gross unrealized appreciation and depreciation of investments aggregated $3,354,329 and $4,312,609, respectively, resulting in net unrealized depreciation of $958,280.
