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 (the Adviser), a wholly owned subsidiary of John Hancock Financial Serivces, 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 evaluated prices 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.

In deciding whether to make a fair value adjustment to the price of a security, the Board of Trustees or their designee may review a variety of factors, including developments in foreign markets, the performance of U.S. securities markets and the performance of instruments trading in U.S. markets that represent foreign securities and baskets of foreign securities. The Fund may also fair value securities in other situations, for example, when a particular foreign market is closed, but the Fund is calculating the net asset value. In view of these factors, it is likely that a Fund investing significant amounts of assets in securities in foreign markets will be fair valued more frequently than a Fund investing significant amounts of assets in frequently traded, U.S. exchange listed securities of large-capitalization U.S. issuers.

For purposes of determining when fair value adjustments may be appropriate with respect to investments in securities in foreign markets that close prior to the NYSE, the Fund will, on an ongoing basis, monitor for “significant market events.” A significant market event may be a certain percentage change in the value of an index that tracks foreign markets in which Fund has significant investments. If a significant market event occurs due to a change in the value of the index, the pricing for investments in foreign markets that have closed prior to the NYSE will promptly be reviewed and potential adjustments to the net asset value will be recommended to the Fund’s Pricing Committee where applicable. Valuations change in response to many factors including the historical and prospective earnings of the issuer, the value of the issuer’s assets, general economic conditions, interest rates, investor perceptions and market liquidity.

Investment Risk
The Fund may invest a portion of its assets in issuers and/or securities of issuers that hold mortgage securities, including subprime mortgage securities. The value of these securities is sensitive to changes in economic conditions, including delinquencies and/or defaults, and may be adversely affected by shifts in the market’s perception of the issuers and changes in interest rates.


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 th 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. When a Fund enters into a repurchase agreement, it receives delivery of collateral, the amount of which at the time of purchase and each subsequent business day is required to be maintained at such a level that the value is generally 102% of the repurchase amount.

Securities lending
The Fund may lend portfolio securities from time to time in order to earn additional income. The Fund retains beneficial ownership of the securities it has loaned and continues to receive interest and dividends paid by the issuer of securities and to participate in any changes in their value. On the settlement date of the loan, the Fund receives cash collateral against the loaned securities and maintains the cash collateral in an amount not less than 100% of the market value of the loaned securities 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 cash collateral is delivered to the Fund on the next business day. Cash collateral received is invested in the JHCIT. If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, a fund could experience delays and costs in recovering the securities loaned or in gaining access to the collateral. The Fund may receive compensation for lending their securities either in the form of fees, guarantees, and/or by retaining a portion of interest on the investment of any cash received as collateral.

The Fund has entered into an agreement with Morgan Stanley & Co., Inc. and MS Securities Services, Inc. (collectively, Morgan Stanley) which permits the Fund to lend securities to Morgan Stanley on a principal basis. Morgan Stanley is the primary borrower of securities of the Fund. The risk of having one primary borrower of Fund securities (as opposed to several borrowers) is that should Morgan Stanley fail financially, all securities lent will be affected by the failure and by any delays in recovery of the securities (or in the rare event, loss of rights in the collateral).
