Prospectus

The fund may invest in Fidelity^® Commodity Strategy Central Fund (commodity central fund), which in turn invests in a wholly-owned subsidiary that invests in commodity-linked derivative instruments. Until December 31, 2012, Fidelity Management & Research Company (FMR) had contractually agreed to waive the fund's management fee in an amount equal to its proportionate share of the management fee paid to FMR by the subsidiary based on the fund's proportionate ownership of the commodity central fund. This arrangement was terminated effective December 31, 2012, when Geode Capital Management, LLC, a registered commodity pool operator, was appointed as the manager of the commodity central fund and its subsidiary. Effective December 31, 2012, Geode has contractually agreed to waive the management fee it receives with respect to the commodity central fund in an amount equal to the management fee paid to Geode by the subsidiary. This reimbursement arrangement is unrelated to the expenses of the fund to which this prospectus relates.
