AB Small Cap Growth Portfolio Class K (QUAKX)

The fund invests primarily in a diversified portfolio of equities with relatively smaller capitalizations as compared to the overall U.S. market. It invests at least 80% of its net assets in equities of smaller companies. For these purposes, "smaller companies" are those that, at the time of investment, fall within the lowest 20% of the total U.S. equity market capitalization (excluding, for purposes of this calculation, companies with market capitalizations of less than $10 million). The fund may invest in any company and industry and in any type of equity security with potential for capital appreciation.
