The following information replaces similar information found in the “Fund Summary” section under the “Fee Table” heading.

Annual Operating Expenses

(expenses that you pay each year as a % of the value of your investment)

Management fee		0.20%
Distribution and/or Service (12b-1) fees		None
Other expenses		0.05%
Total annual operating expenses		0.25%
Fee waiver and/or expense reimbursement(a)		0.05%
Total annual operating expenses after fee waiver and/or expense reimbursement(b)		0.20%

(a)  Fidelity Management & Research Company LLC (FMR) has contractually agreed to reimburse Institutional Class of the fund to the extent that total operating expenses (excluding interest, certain taxes, fees and expenses of the Independent Trustees, extraordinary expenses, and acquired fund fees and expenses, if any, as well as non-operating expenses such as brokerage commissions and fees and expenses associated with the fund's securities lending program, if applicable), as a percentage of its average net assets, exceed 0.20% (the Expense Cap). If at any time during the current fiscal year expenses for Institutional Class of the fund fall below the Expense Cap, FMR reserves the right to recoup through the end of the fiscal year any expenses that were reimbursed during the current fiscal year up to, but not in excess of, the Expense Cap. This arrangement will remain in effect for at least one year from the effective date of the prospectus. FMR may not terminate this arrangement without the approval of the Board of Trustees and may extend it in its discretion after that date.

(b)  In order to avoid a negative yield, FMR may reimburse expenses or waive fees of Institutional Class. Any such waivers or expense reimbursement would be voluntary and could be discontinued at any time. There is no guarantee that Institutional Class or the fund will be able to avoid a negative yield.

The following information replaces similar information found in the “Fund Basics” section under the “Principal Investment Risks” heading.

Many factors affect the fund's performance. Developments that disrupt global economies and financial markets, such as pandemics and epidemics, may magnify factors that affect a fund’s performance. Because the fund concentrates its investments in Massachusetts, the fund's performance is expected to be closely tied to economic and political conditions within that state and to be more volatile than the performance of a more geographically diversified fund.
