Notes to portfolio of investments

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 (JHA), a wholly owned subsidiary of John Hancock Financial Services, Inc., a subsidiary of 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 a 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 their 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 a 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 their 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 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.

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, 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 its securities either in the form of fees or by retaining a portion of interest on the investment of any cash received as collateral. The Fund invests in cash collateral received in connection with securities lending transactions in JHCIT, a Delaware common law trust and an affiliated 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 JHCIT.

Notes to Schedule of Investments - Page 2


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.

Financial futures contracts

The Fund may purchase and sell financial futures contracts and options on those contracts. The Fund invests in contracts based on financial instruments such as U.S. Treasury Bonds or Notes or on securities indices such as the Standard & Poor’s 500 Index, in order to hedge against a decline in the value of securities owned by the Fund.

Initial margin deposits required upon entering into futures contracts are satisfied by the delivery of specific securities or cash as collateral to the broker (the Funds’ agent in acquiring the futures position). If the position is closed out by taking an opposite position prior to the settlement date of the futures contract, a final determination of variation margin is made, cash is required to be paid to or released by the broker and the Fund realizes a gain or loss.

When the Fund sells a futures contract based on a financial instrument, the Fund becomes obligated to deliver that kind of instrument at an agreed upon date for a specified price. The Fund realizes a gain or loss depending on whether the price of an offsetting purchase is less or more than the price of the initial sale or on whether the price of an offsetting sale is more or less than the price of the initial purchase. The Fund could be exposed to risks if it could not close out futures positions because of an illiquid secondary market or the inability of counterparties to meet the terms of their contracts. Futures contracts are valued at the quoted daily settlement prices established by the exchange on which they trade.

Swap contracts

The Fund may enter into swap transactions in order to hedge the value of the Fund’s portfolio against interest rate fluctuations or to enhance the Fund’s income. Interest rate swaps represent an agreement between two counterparties to exchange cash flows based on the difference in the two interest rates, applied to the notional principal amount for a specified period. The payment flows are usually netted against each other, with the difference being paid by one party to the other. The Fund settles accrued net receivable or payable under the swap contracts on a periodic basis.

The Fund records changes in the value of the swaps as unrealized gains or losses on swap contracts. Net periodic payments accrued, but not yet received (paid) are included in change in the unrealized appreciation/ depreciation.

Accrued interest income and interest expense on the swap contracts are recorded as realized gain (loss).

Swap contracts are subject to risks related to the counterparty’s ability to perform under the contract, and may decline in value if the counterparty’s creditworthiness deteriorates.

The risks may arise from unanticipated movement in interest rates. The Fund may also suffer losses if it is unable to terminate outstanding swap contracts or reduce its exposure through offsetting transactions.
