Example

The Example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the fund for the time periods indicated and then hold or redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example - BNY Mellon International Stock Index Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Investor Shares	61	192	335	750
Class I	36	113	197	443

Expense Example No Redemption - BNY Mellon International Stock Index Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Investor Shares	61	192	335	750
Class I	36	113	197	443

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 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 fund operating expenses or in the Example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 7.58% of the average value of its portfolio.

Principal Investment Strategy

To pursue its goal, the fund generally is fully invested in stocks included in the Morgan Stanley Capital International Europe, Australasia, Far East (MSCI EAFE⁾ Index and in futures whose performance is tied to certain countries included in the index. The fund generally invests in all stocks included in the index. The fund's investments are selected to match the benchmark composition along individual name, country and industry weighting, and other benchmark characteristics. Under these circumstances, the fund maintains approximately the same weighting for each stock as the index does.

The MSCI EAFE Index is an unmanaged, free float-adjusted market capitalization index that is designed to measure the equity market performance of developed markets, excluding the United States and Canada. Each stock in the index is weighted by its float-adjusted market capitalization.

Principal Risks

An investment in the fund is not a bank deposit. It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. It is not a complete investment program. The fund's share price fluctuates, sometimes dramatically, which means you could lose money.

·Risks of stock investing. Stocks generally fluctuate more in value than bonds and may decline significantly over short time periods. There is the chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising prices and falling prices. The market value of a stock may decline due to general market conditions or because of factors that affect the particular company or the company's industry.

·Indexing strategy risk. The fund uses an indexing strategy. It does not attempt to manage market volatility, use defensive strategies or reduce the effects of any long-term periods of poor index performance. The correlation between fund and index performance may be affected by the fund's expenses, changes in securities markets, changes in the composition of the index and the timing of purchases and redemptions of fund shares.

·Foreign investment risk. To the extent the fund invests in foreign securities, the fund's performance will be influenced by political, social and economic factors affecting investments in foreign issuers. Special risks associated with investments in foreign issuers include exposure to currency fluctuations, less liquidity, less developed or less efficient trading markets, lack of comprehensive company information, political and economic instability and differing auditing and legal standards. Investments denominated in foreign currencies are subject to the risk that such currencies will decline in value relative to the U.S. dollar and affect the value of these investments held by the fund.

·Risk of investing in Japan and the United Kingdom. The MSCI EAFE^® Index may be comprised of a large percentage of securities of companies organized in Japan or the United Kingdom (UK). To the extent the fund invests a significant portion of its assets in the securities of companies organized in Japan or the UK, it is more likely to be impacted by events or conditions affecting those countries. The risk of investing in the UK may be heightened due to the UK's withdrawal from membership in the European Union (known as "Brexit"). The terms of the UK's exit from the European Union are not clear and the shape of the regulatory landscape is not yet defined. The current uncertainty and related future developments could have a negative impact on both the UK's economy and the economies of the other countries in Europe, as well as greater volatility in the global financial and currency markets.

·Foreign currency risk. Investments in foreign currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedged positions, that the U.S. dollar will decline relative to the currency being hedged. Foreign currencies are also subject to risks caused by inflation, interest rates, budget deficits and low savings rates, political factors and government intervention and controls.

·Non-diversification risk. The fund is non-diversified, which means that the fund may invest a relatively high percentage of its assets in a limited number of issuers. Therefore, the fund's performance may be more vulnerable to changes in the market value of a single issuer or group of issuers and more susceptible to risks associated with a single economic, political or regulatory occurrence than a diversified fund.

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the performance of the fund's Investor shares from year to year. The table compares the average annual total returns of the fund's shares to those of a broad measure of market performance. The fund's past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future. More recent performance information may be available at www.bnymellonim.com/us. Prior to August 31, 2016, the fund's Investor shares were undesignated.

Average Annual Total Returns (as of 12/31/19)

After-tax performance is shown only for Investor shares. After-tax performance of the fund's other share class will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates, and do not reflect the impact of state and local taxes. Actual after-tax returns depend on the investor's tax situation and may differ from those shown, and the after-tax returns shown are not relevant to investors who hold their shares through U.S. tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

For the fund's Class I shares, periods prior to the inception date reflect the performance of the fund's Investor shares. Such performance figures have not been adjusted to reflect applicable class expenses. Each share class is invested in the same portfolio of securities, and the annual returns would have differed only to the extent that the classes have different expenses.
