Foreign Currency Transactions. Although a forward foreign currency exchange contract is used to reduce or hedge a fund’s exposure to changes in the value of the currency, suitable hedging transactions may not be available in all circumstances, may not be successful, and may eliminate any chance for the fund to benefit from favorable fluctuations in relevant foreign currencies.

Effective June 1, 2017, the following information replaces similar information found in the "Fund Basics" section under the heading "Principal Investment Strategies".

The Adviser invests the fund's assets in securities issued throughout the world, including securities of issuers located in emerging markets. The Adviser normally invests at least 80% of the fund's assets in debt securities of all types and repurchase agreements for those securities. The Adviser normally invests the fund's assets primarily in investment-grade debt securities.

The Adviser normally allocates the fund's investments across different countries and regions, including the United States.

The Adviser invests the fund's assets in both U.S. dollar-denominated and non-U.S. dollar-denominated securities, and will hedge the fund’s foreign currency exposures utilizing forward foreign currency exchange contracts.

The Adviser considers other factors when selecting the fund's investments, including the credit quality of the issuer, security-specific features, current valuation relative to alternatives in the market, short-term trading opportunities resulting from market inefficiencies, and potential future valuation. In managing the fund's exposure to various risks, including interest rate risk, the Adviser considers, among other things, the market's overall risk characteristics, the market's current pricing of those risks, information on the fund's competitive universe and internal views of potential future market conditions. The Adviser's analysis also considers the credit, currency, and economic risks associated with a security and the country of its issuer. The Adviser may also consider an issuer's potential for success in light of its current financial condition, its industry position, and economic and market conditions.

The Adviser may invest up to 20% of the fund's assets in lower-quality debt securities (those of less than investment-grade quality, also referred to as high yield debt securities or junk bonds).

The Adviser may also invest a portion of the fund’s assets in hybrid and preferred securities.

The Adviser may engage in transactions that have a leveraging effect on the fund, including investments in derivatives, regardless of whether the fund may own the asset, instrument, currency, or components of the index underlying the derivative, and forward-settling securities. The Adviser may invest a significant portion of the fund's assets in these types of investments. If the fund invests a significant portion of its assets in derivatives, its investment exposure could far exceed the value of its portfolio securities and its investment performance could be primarily dependent upon securities it does not own. In addition to forward foreign currency exchange contracts, the fund's derivative investments may include interest rate swaps, total return swaps, credit default swaps, options (including options on futures and swaps), forwards, and futures contracts (both long and short positions) on securities, other instruments, indexes, or currencies. Depending on the Adviser's outlook and market conditions, the Adviser may engage in these transactions to increase or decrease the fund's exposure to changing security prices, interest rates, credit qualities, foreign exchange rates, or other factors that affect security values, or to gain or reduce exposure to an asset, instrument, currency, or index.

The Adviser allocates the fund's assets among different market sectors (for example, corporate, asset-backed, or government securities) based on its view of their relative values.

To earn additional income for the fund, the Adviser may use a trading strategy that involves selling (or buying) mortgage securities and simultaneously agreeing to purchase (or sell) mortgage securities on a later date at a set price. This trading strategy may increase interest rate exposure and result in an increased portfolio turnover rate which increases transaction costs and may increase taxable gains.

The Adviser uses central funds to help invest the fund's assets. Central funds are specialized investment vehicles designed to be used by Fidelity^® funds. Fidelity uses them to invest in particular security types or investment disciplines; for example, rather than buy bonds directly, the fund may invest in a central fund that buys bonds. Fidelity does not charge any additional management fees for central funds. Central funds offer exposure to some or all of the following types of investment-grade and lower-quality debt securities (those of less than investment-grade quality, also referred to as high yield debt securities or junk bonds): corporate bonds, mortgage and other asset-backed securities, floating rate loans, and BB-rated securities. Central funds may also focus on other types of securities.

If the Adviser's strategies do not work as intended, the fund may not achieve its objective.

Effective June 1, 2017, the following information supplements similar information found in the "Fund Basics" section under the heading "Principal Investment Risks".

Foreign Currency Transactions. A fund that invests in securities denominated in foreign currencies may enter into forward foreign currency exchange contracts. A forward foreign currency exchange contract, which involves an obligation to purchase or sell a specific currency at a future date at a price set at the time of the contract, reduces a fund’s exposure to changes in the value of the currency it will deliver and increases its exposure to changes in the value of the currency it will receive for the duration of the contract. Certain foreign currency transactions may also be settled in cash rather than the actual delivery of the relevant currency. A contract to sell a foreign currency would limit any potential gain that might be realized if the value of the hedged currency increases. Suitable hedging transactions may not be available in all circumstances, may not be successful, and may eliminate any chance for the fund to benefit from favorable fluctuations in relevant foreign currencies.

Hybrid and Preferred Securities Risk. The risks of investing in hybrid and preferred securities reflect a combination of the risks of investing in securities, options, futures and currencies. An investment in a hybrid or preferred security may entail significant risks that are not associated with a similar investment in a traditional debt or equity security. The risks of a particular hybrid or preferred security will depend upon the terms of the instrument, but may include the possibility of significant changes in the value of any applicable reference instrument. Such risks may depend upon factors unrelated to the operations or credit quality of the issuer of the hybrid or preferred security. Hybrid and preferred securities are potentially more volatile and carry greater market and liquidity risks than traditional debt or equity securities. Also, the price of the hybrid or preferred security and any applicable reference instrument may not move in the same direction or at the same time.

Effective June 1, 2017, the following information replaces similar information found in the “Shareholder Information” section under the heading “Dividends and Capital Gain Distributions”.

The fund normally pays dividends, if any, quarterly in April, July, October, and December and capital gain distributions in February and December.
