Fidelity Series Emerging Markets Fund

Fund Summary

Fund:
Fidelity^® Series Emerging Markets Fund

Investment Objective

The fund seeks capital appreciation.

Fee Table

The following table describes the fees and expenses that may be incurred when you buy and hold shares of the fund.

Shareholder fees
(fees paid directly from your investment)

Shareholder Fees	Fidelity Series Emerging Markets Fund Class: Fidelity Series Emerging Markets Fund USD ($)
Shareholder fees (fees paid directly from your investment)	none

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

Annual Operating Expenses	Fidelity Series Emerging Markets Fund Class: Fidelity Series Emerging Markets Fund
Management fee	none
Distribution and/or Service (12b-1) fees	none
Other expenses	0.06%	[1]
Total annual operating expenses	0.06%
Fee waiver and/or expense reimbursement	0.05%	[2]
Total annual operating expenses after fee waiver and/or expense reimbursement	0.01%

This example helps compare the cost of investing in the fund with the cost of investing in other funds.

Let’s say, hypothetically, that the annual return for shares of the fund is 5% and that your shareholder fees and the annual operating expenses for shares of the fund are exactly as described in the fee table. This example illustrates the effect of fees and expenses, but is not meant to suggest actual or expected fees and expenses or returns, all of which may vary. For every $10,000 you invested, here’s how much you would pay in total expenses if you sell all of your shares at the end of each time period indicated:

Expense Example	Fidelity Series Emerging Markets Fund Class: Fidelity Series Emerging Markets Fund USD ($)
1 year	$ 1
3 years	$ 3

Portfolio Turnover

The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual operating expenses or in the example, affect the fund’s performance.

Principal Investment Strategies

• Normally investing at least 80% of assets in securities of issuers in emerging markets (countries that have an emerging stock market as defined by MSCI, countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets with similar emerging characteristics) and other investments that are tied economically to emerging markets.

• Normally investing primarily in common stocks.

• Allocating investments across different emerging market countries.

• Using fundamental analysis of factors such as each issuer’s financial condition and industry position, as well as market and economic conditions, to select investments.

Principal Investment Risks

• Stock Market Volatility. Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or economic developments. Different parts of the market, including different market sectors, and different types of securities can react differently to these developments.

• Foreign and Emerging Market Risk. Foreign markets, particularly emerging markets, can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market. Emerging markets can be subject to greater social, economic, regulatory, and political uncertainties and can be extremely volatile. Foreign exchange rates also can be extremely volatile.

• Issuer-Specific Changes. 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.

An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. You could lose money by investing in the fund.

Performance

Performance history will be available for the fund after the fund has been in operation for one calendar year.

[1] Based on estimated amounts for the current fiscal year.

[2] The Adviser has contractually agreed to reimburse the fund to the extent that total operating expenses (excluding interest, certain taxes, certain securities lending costs, brokerage commissions, fees and expenses of the Independent Trustees, proxy and shareholder meeting expenses, extraordinary expenses, and acquired fund fees and expenses, if any), as a percentage of its average net assets, exceed 0.014% (the Expense Cap). If at any time during the current fiscal year expenses for the fund fall below the Expense Cap, FMR reserves the right to recoup prior reimbursed expenses up to, but not in excess of, the Expense Cap. This arrangement will remain in effect through February 28, 2022. FMR may not terminate this arrangement before the expiration date without the approval of the Board of Trustees.
