Examples

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

Expense Example - AB Global Core Equity Portfolio - USD ($)	Class A	Class C		Advisor Class
After 1 Year	$ 530	$ 287	[1]	$ 86
After 3 Years	754	579		268
After 5 Years	995	995		466
After 10 Years	$ 1,686	$ 2,159		$ 1,037

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys or 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 transaction costs, which are not reflected in the Annual Fund Operating Expenses or in the Examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 52% of the average value of its portfolio.

PRINCIPAL STRATEGIES

The Fund invests primarily in a portfolio of equity securities of issuers from markets around the world. Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities, at least 40% of its net assets in securities of non-U.S. companies, and invests in companies in at least three countries (including the United States).

The Fund is principally comprised of companies considered by the Adviser to offer good prospects for attractive returns relative to the general stock market. The Adviser seeks companies that are attractively valued and have the ability to generate high and sustainable returns on invested capital. In addition to returns on invested capital, other criteria that the Adviser considers include strong business fundamentals, capable management, prudent corporate governance, strong balance sheet, strong earnings power, high earnings quality, low downside risk, and substantial upside potential. In managing the Fund, the Adviser does not seek to have a bias towards any investment style, economic sector, country or company size. The Fund’s holdings of non-U.S. companies frequently include companies located in emerging markets, and at times emerging market companies will make up a significant portion of the Fund.

Fluctuations in currency exchange rates can have a dramatic impact of the returns of equity securities. While the Adviser may hedge the foreign currency exposure resulting from the Fund’s security positions through the use of currency-related derivatives, it is not required to do so.

PRINCIPAL RISKS

• Market Risk: The value of the Fund’s assets will fluctuate as the stock or bond market fluctuates. The value of its investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events, including public health crises (including the occurrence of a contagious disease or illness), that affect large portions of the market. It includes the risk that a particular style of investing may underperform the market generally.

• Foreign (Non-U.S.) Risk: Investments in securities of non-U.S. issuers may involve more risk than those of U.S. issuers. These securities may fluctuate more widely in price and may be more difficult to trade due to adverse market, economic, political, regulatory or other factors.

• Emerging Market Risk: Investments in emerging market countries may have more risk because the markets are less developed and less liquid as well as being subject to increased economic, political, regulatory or other uncertainties.

• Currency Risk: Fluctuations in currency exchange rates may negatively affect the value of the Fund’s investments or reduce its returns.

• Sector Risk: The Fund may have more risk because it may invest to a significant extent in one or more particular market sectors, such as the information technology or financial services sector. To the extent it does so, market or economic factors affecting the relevant sector(s) could have a major effect on the value of the Fund’s investments.

• Management Risk: The Fund is subject to management risk because it is an actively-managed investment fund. The Adviser will apply its investment techniques and risk analyses in making investment decisions for the Fund, but there is no guarantee that its techniques will produce the intended results. Some of these techniques may incorporate, or rely upon, quantitative models, but there is no guarantee that these models will generate accurate forecasts, reduce risk or otherwise perform as expected.

As with all investments, you may lose money by investing in the Fund.

BAR CHART AND PERFORMANCE INFORMATION

The bar chart and performance information provide an indication of the historical risk of an investment in the Fund by showing:

• how the Fund’s performance changed from year to year over the life of the Fund; and​​​​​​​

• how the Fund’s average annual returns for one year, five years and since inception compare to those of a broad-based securities market index.

You may obtain updated performance information on the Fund’s website at www.abfunds.com (click on “Investments—Mutual Funds”).

The Fund’s past performance before and after taxes, of course, does not necessarily indicate how it will perform in the future.

During the period shown in the bar chart, the Fund’s:

Best Quarter was up 12.35%, 1st quarter, 2019; and Worst Quarter was down -10.36%, 4th quarter, 2018.

[1] Purchases of Class A shares in amounts of $1,000,000 or more, or by certain group retirement plans, may be subject to a 1%, 1-year contingent deferred sales charge, or CDSC, which may be subject to waiver in certain circumstances.

[2] For Class C shares, the CDSC is 0% after the first year. Class C shares automatically convert to Class A shares after ten years.

[1] If you did not redeem your shares at the end of the period, your expenses would be decreased by approximately $100.

[1] After-tax returns: – Are shown for Class A shares only and will vary for the other Classes of shares because these Classes have different expense ratios; – Are an estimate, which is based on the highest historical individual federal marginal income tax rates, and do not reflect the impact of state and local taxes; actual after-tax returns depend on an individual investor’s tax situation and are likely to differ from those shown; and – Are not relevant to investors who hold fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.
