Regulatory restrictions may limit the amount that one fund can invest in another, which means that the fund's manager may not be able to invest as much as it wants to in some other funds. The fund bears all risks of investment strategies employed by the underlying funds, including the risk that the underlying funds will not meet their investment objectives. Underlying funds that are passively managed attempt to track the performance of an unmanaged index of securities and as such their performance could be lower than actively managed funds, which may shift their portfolio assets to take advantage of market opportunities or lessen the impact of a market decline. In addition, errors in the construction of the index tracked by an underlying passively managed fund may have an adverse impact on the performance of such underlying fund.

Normally investing at least 80% of assets in municipal securities whose interest is exempt from federal income tax. The municipal securities in which the fund invests are normally investment-grade (those of medium and high quality).
Municipal debt securities are issued to raise money for a variety of public and private purposes, including general financing for state and local governments, financing for eligible non-profit organizations, or financing for a specific project or public facility. Municipal debt securities in which the fund invests include securities issued by U.S. territories and possessions, general obligation bonds of municipalities, local or state governments, project or revenue-specific bonds, or pre-refunded or escrowed bonds, municipal money market securities, and synthetic securities. Municipal securities usually pay a fixed, variable, or floating rate of interest, and must repay the amount borrowed, usually at the maturity of the security. Municipal debt securities also include shares of underlying funds (including mutual funds and ETFs) that invest at least 80% of assets in municipal debt securities.
Investment grade securities in which the fund invests include securities or issuers rated at least BBB- or its equivalent by at least one nationally recognized statistical ratings organization (NRSRO), or, if unrated, determined by the Adviser to be of comparable quality.
Derivative instruments that provide investment exposure to the investments above or exposure to one or more market risk factors associated with such investments are included in the fund's 80% policy, consistent with the fund's investment policies and limitations with respect to investments in derivatives.
Normally investing primarily in investment-grade municipal securities.Allocating assets across different market sectors and maturities.Potentially investing more than 25% of total assets in municipal securities that finance similar types of projects.Implementing investment strategies by investing directly in securities through one or more managers (sub-advisers) or indirectly in securities through one or more other funds, referred to as underlying funds, which in turn invest directly in securities (as described below).Allocating assets among affiliated funds (i.e., Fidelity&#xae; funds, including mutual funds and ETFs), non-affiliated funds and non-affiliated ETFs.Allocating assets among sub-advisers and underlying funds using proprietary fundamental and quantitative research, considering factors including, but not limited to, performance in different market environments, manager experience and investment style, management company infrastructure, costs, asset size, and portfolio turnover.Investing up to 30% in lower-quality debt securities (those of less than investment-grade quality, also referred to as high yield debt securities or junk bonds).Analyzing the credit quality of the issuer, the issuer's potential for success, the credit, currency and economic risks of the security and its issuer, security-specific features, current and potential future valuation, and trading opportunities to select investments.
Pursuant to an exemptive order granted by the Securities and Exchange Commission (SEC), Strategic Advisers LLC (Strategic Advisers) is permitted, subject to the approval of the Board of Trustees, to enter into new or amended sub-advisory agreements with one or more unaffiliated sub-advisers without obtaining shareholder approval of such agreements. Subject to oversight by the Board of Trustees, Strategic Advisers has the ultimate responsibility to oversee the fund's sub-advisers and recommend their hiring, termination, and replacement. In the event the Board of Trustees approves a sub-advisory agreement with a new unaffiliated sub-adviser, shareholders will be provided with information about the new sub-adviser and sub-advisory agreement.

Regulatory restrictions may limit the amount that one fund can invest in another, which means that the fund's manager may not be able to invest as much as it wants to in some other funds. The fund bears all risks of investment strategies employed by the underlying funds, including the risk that the underlying funds will not meet their investment objectives. Underlying funds that are passively managed attempt to track the performance of an unmanaged index of securities and as such their performance could be lower than actively managed funds, which may shift their portfolio assets to take advantage of market opportunities or lessen the impact of a market decline. In addition, errors in the construction of the index tracked by an underlying passively managed fund may have an adverse impact on the performance of such underlying fund.

The value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.
A decline in the credit quality of an issuer or a provider of credit support (such as guarantees) or a maturity-shortening structure (such as demand and put features) for a security can cause the price of a security to decrease.
Lower-quality debt securities (those of less than investment-grade quality, also referred to as high yield debt securities or junk bonds) and certain types of other securities involve greater risk of default or price changes due to changes in the credit quality of the issuer. The value of lower-quality debt securities and certain types of other securities can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market, or economic developments and can be difficult to resell.
