These securities may be sold in the ordinary course of business in transactions exempt from registration, normally to qualified institutional buyers. At period end, the aggregate value of these securities was $183,609,505 representing 49.2% of net assets.

(x) Commodity-linked notes typically provide for interest and principal payments based on the value of a commodity indicator, such as a commodity, a commodity future or option contract, a commodity index, or some other indicator that reflects the value of a particular commodity or commodity market or the difference between one or more commodity or commodity markets. Commodity-linked notes have characteristics of instruments indirectly linked to the price of commodities and are subject to basis risk, the risk that there can be deviations in performance between the physical commodity market and the futures price, and counter party risk. Commodity-linked notes can be highly volatile and less liquid than other types of investments. These structured notes take into consideration a leverage factor of 300% on the return of the commodity indicator at the time the note is purchased, in order to limit counterparty exposure.

(1) Investment Valuations

Debt instruments and floating rate loans (other than short-term instruments), including restricted debt instruments, are generally valued at an evaluated or composite bid as provided by a third-party pricing service. Short-term instruments with a maturity at issuance of 60 days or less generally are valued at amortized cost, which approximates market value. Futures contracts are generally valued at last posted settlement price as provided by a third-party pricing service on the market on which they are primarily traded. Futures contracts for which there were no trades that day for a particular position are generally valued at the closing bid quotation as provided by a third-party pricing service on the market on which such futures contracts are primarily traded. Open-end investment companies are generally valued at net asset value per share. Securities and other assets, including commodity-linked structured notes, generally valued on the basis of information from a third-party pricing service may also be valued at a broker/dealer bid quotation. Values obtained from third-party pricing services can utilize both transaction data and market information such as yield, quality, coupon rate, maturity, type of issue, trading characteristics, and other market data. The values of foreign securities and other assets and liabilities expressed in foreign currencies are converted to U.S. dollars using the mean of bid and asked prices for rates provided by a third-party pricing service.

The Board of Trustees has delegated primary responsibility for determining or causing to be determined the value of the fund’s investments (including any fair valuation) to the adviser pursuant to valuation policies and procedures approved by the Board. If the adviser determines that reliable market quotations are not readily available, investments are valued at fair value as determined in good faith by the adviser in accordance with such procedures under the oversight of the Board of Trustees. Under the fund’s valuation policies and procedures, market quotations are not considered to be readily available for most types of debt instruments and floating rate loans and many types of derivatives. These investments are generally valued at fair value based on information from third-party pricing services. In addition, investments may be valued at fair value if the adviser determines that an investment’s value has been materially affected by events occurring after the close of the exchange or market on which the investment is principally traded (such as foreign exchange or market) and prior to the determination of the fund’s net asset value, or after the halting of trading of a specific security where trading does not resume prior to the close of the exchange or market on which the security is principally traded. The adviser generally relies on third-party pricing services or other information (such as the correlation with price movements of similar securities in the same or other markets; the type, cost and investment characteristics of the security; the business and financial condition of the issuer; and trading and other market data) to assist in determining whether to fair value and at what value to fair value an investment. The value of an investment for purposes of calculating the fund’s net asset value can differ depending on the source and method used to determine value. When fair valuation is used, the value of an investment used to determine the fund’s net asset value may differ from quoted or published prices for the same investment. There can be no assurance that the fund could obtain the fair value assigned to an investment if it were to sell the investment at the same time at which the fund determines its net asset value per share.

Various inputs are used in determining the value of the fund’s assets or liabilities. These inputs are categorized into three broad levels. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investment’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The fund’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the investment. Level 1 includes unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 includes other significant observable market-based inputs (including quoted prices for similar securities, interest rates, prepayment speed, and credit risk). Level 3 includes unobservable inputs, which may include the adviser’s own assumptions in determining the fair value of investments. Other financial instruments are derivative instruments not reflected in total investments, such as futures contracts. The following is a summary of the levels used as of January 31, 2013 in valuing the fund’s assets or liabilities:

Commodity-Linked Structured Notes – The fund invests in commodity-linked structured notes, to provide exposure to the investment returns of the commodities markets without investing directly in commodities. The fund will not invest directly in commodities. A structured note is a type of debt instrument in which an issuer borrows money from the investor, in this case the fund, and pays back the principal

adjusted for performance of the underlying index less a fee. The structured notes may be leveraged, increasing the volatility of each note’s value relative to the change in the underlying linked financial element. The value of these notes will rise and fall in response to changes in the underlying commodity or related index or investment. These notes are subject to prepayment, basis, and counterparty risk. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the fund may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The fund may obtain only a limited recovery or may obtain no recovery in such circumstances. There is additional risk that the issuer or counterparty may be unable or unwilling to make timely payments of interest or principal. To partially mitigate this risk, MFS typically enters into these transactions with counterparties whose credit rating is investment grade. Commodity-linked structured notes are valued daily by the issuing counterparties under procedures approved by the fund’s Board of Trustees. The structured notes have an automatic redemption feature if the underlying index declines from the entrance date by the amount specified in the agreement. The fund has the option to request prepayment from the issuer at any time. The issuer of the structured note may, under certain circumstances, call back the securities on a date earlier than the maturity date. The net cash payments exchanged, which might require calculation by the issuer or its affiliates, are recorded as a realized gain or loss on investments in the Statement of Operations. The value of the structured note, which is adjusted daily and includes any related interest accruals to be received and fees to be paid by the fund, is recorded on the Statement of Assets and Liabilities. The daily change in value, including any related interest accruals to be received and fees to be paid, is recorded as unrealized appreciation or depreciation on investments in the Statement of Operations. The fund records a realized gain or loss when a structured note is sold or matures.
