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. The one-year example and the first year of the three-, five- and ten-years examples are based on net operating expenses, which reflect the expense limitation by The Dreyfus Corporation. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example	1 Year	3 Years	5 Years	10 Years

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 117.57% of the average value of its portfolio.

Principal Investment Strategy

To pursue its goal, the fund normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in common stocks and other equity securities of small cap foreign companies. The fund considers foreign companies to be those companies organized or with their principal place of business, or majority of assets or business, in countries represented in the S&P^® Developed Ex-U.S. Small Cap Index, the fund’s benchmark. The fund considers small cap companies to be those companies with total market capitalizations that fall within the range of the capitalizations of the companies that comprise the S&P^® Developed Ex-U.S. Small Cap Index. The S&P^® Developed Ex-U.S. Small Cap Index is a market capitalization weighted index designed to define and measure the investable universe of publicly traded small cap companies domiciled in developed countries outside the United States. As of January 31, 2017, the total market capitalizations of the largest and smallest companies in the S&P^® Developed Ex-U.S. Small Cap Index were approximately $9.4 billion and $15 million, respectively, and the mean and median total market capitalizations of the Index were approximately $13.5 billion and $18 million, respectively.

The fund invests in stocks that appear to be undervalued (as measured by their price/earnings ratios) and that may have value and/or growth characteristics. The fund’s portfolio managers employ a bottom-up investment approach using proprietary quantitative models and traditional qualitative analysis to identify attractive stocks. The portfolio managers seek to allocate country weights generally in accordance with the S&P^® Developed Ex-U.S. Small Cap Index and use the sector weightings of the Index as a guide, but the fund’s country and sector weightings may vary from those of the Index.

The fund’s stock selection process is designed to produce a diversified portfolio that, relative to the S&P^® Developed Ex-U.S. Small Cap Index, has a below-average price/earnings ratio and an above-average earnings growth trend.

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.

·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.

·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. Currency exchange rates may fluctuate significantly over short periods of time. 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.

·Small and midsize company risk. Small and midsize companies carry additional risks because the operating histories of these companies tend to be more limited, their earnings and revenues less predictable (and some companies may be experiencing significant losses), and their share prices more volatile than those of larger, more established companies. The shares of smaller companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the fund's ability to sell these securities.

·Growth and value stock risk. By investing in a mix of growth and value companies, the fund assumes the risks of both. Investors often expect growth companies to increase their earnings at a certain rate. If these expectations are not met, investors can punish the stocks inordinately, even if earnings do increase. In addition, growth stocks may lack the dividend yield that may cushion stock prices in market downturns. Value stocks involve the risk that they may never reach their expected full market value, either because the market fails to recognize the stock's intrinsic worth or the expected value was misgauged. They also may decline in price even though in theory they are already undervalued.

·Portfolio turnover risk. The fund may engage in short-term trading, which could produce higher transaction costs and taxable distributions, and lower the fund's after-tax performance.

·Liquidity risk. When there is little or no active trading market for specific types of securities, it can become more difficult to sell the securities in a timely manner at or near their perceived value. In such a market, the value of such securities and the fund's share price may fall dramatically. Investments that are illiquid or that trade in lower volumes may be more difficult to value. Investments in foreign securities tend to have greater exposure to liquidity risk than domestic securities.

Performance

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 Class T shares from year to year. Sales charges are not reflected in the bar chart, and, if those charges were included, returns would have been less than those shown. The table compares the average annual total returns of the fund's Class T 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.dreyfus.com.

The historical performance of the fund's Class A shares, which are not offered in this prospectus, is used to calculate the performance of the fund's Class T shares shown in the bar chart and table. Since the fund's Class T shares are new, past performance information is not available for Class T shares as of the date of this prospectus. 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 do not have the same charges and expenses. The performance figures in the table have been adjusted to reflect the sales load applicable to the fund's Class T shares. The performance figures have not been adjusted to reflect applicable class fees and expenses.

Average Annual Total Returns (as of 12/31/16)

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. Returns after taxes on distributions and sale of fund shares may be higher than returns before taxes or returns after taxes on distributions due to an assumed tax benefit from losses on a sale of the fund's shares at the end of the period.
