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 Funds performance. During the most recent fiscal period, the Funds portfolio turnover rate was 269% of the average value of its portfolio.

DIVERSIFICATION RISK:  The Fund may have more risk because it is non-diversified, meaning that it can invest more of its assets in a smaller number of issuers.

Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities of U.S. companies. For purposes of this requirement, equity securities include common stock, preferred stock and derivatives related to common and preferred stocks. The Adviser selects investments for the Fund through an intensive bottom-up approach that places an emphasis on companies that are engaged in business activities with solid long-term growth potential and operating in industries with high barriers to entry, that have strong cash flows and other financial metrics, and that have transparent financial statements and business models. The Adviser also evaluates the quality of company management based on a series of criteria, including: (1) managements focus on shareholder returns, such as through a demonstrated commitment to dividends and dividend growth, share buybacks or other shareholder-friendly corporate actions; (2) managements employment of conservative accounting methodologies; (3) management incentives, such as direct equity ownership; and (4) management accessibility. The Adviser seeks to identify companies where events or catalysts may drive the companys share price higher, such as earnings and/or revenue growth above consensus forecasts, potential market recognition of undervaluation or overstated market-risk discount, or the institution of shareholder-focused changes discussed in the preceding sentence. In light of this catalyst-focused approach, the Adviser expects to engage in active and frequent trading for the Fund. The Adviser may reduce or eliminate the Funds holdings in a companys securities for a number of reasons, including if its evaluation of the above factors changes adversely, if the anticipated events or catalysts do not occur or do not affect the price of the securities as expected, or if the anticipated events or catalysts do occur and cause the securities to be, in the Advisers view, overvalued or fully valued. At any given time the Fund may emphasize growth stocks over value stocks, or vice versa. The Funds investments will be focused on securities of companies with large and medium market capitalizations, but it may also invest in securities of small-capitalization companies. The Adviser anticipates that the Funds portfolio normally will include between 30-80 companies. The Fund may invest in non-U.S. companies, but will limit its investments in such companies to no more than 10% of its net assets. The Fund may purchase securities in initial public offerings and expects to do so on a regular basis. <ul type="square"><li>MARKET RISK:  The value of the Funds assets will fluctuate as the stock, bond or currency markets fluctuate. The value of the Funds investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events that affect large portions of the market.</li></ul><ul type="square"><li>CAPITALIZATION RISK:  Investments in small- and mid-capitalization companies may be more volatile than investments in large-capitalization companies. Investments in these companies may have additional risks because these companies may have limited product lines, markets or financial resources.</li></ul><ul type="square"><li>DIVERSIFICATION RISK:  The Fund may have more risk because it is non-diversified, meaning that it can invest more of its assets in a smaller number of issuers. Accordingly, changes in the value of a single security may have a more significant effect, either negative or positive, on the Funds net asset value, or NAV.</li></ul><ul type="square"><li>ACTIVE TRADING RISK:  The Fund expects to engage in active and frequent trading of its portfolio securities and its portfolio turnover rate may greatly exceed 100%. A higher rate of portfolio turnover increases transaction costs, which may negatively affect the Funds return. In addition, a high rate of portfolio turnover may result in substantial short-term gains, which may have adverse tax consequences for Fund shareholders.</li></ul><ul type="square"><li>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, but there is no guarantee that its techniques will produce the intended results.</li></ul>As with all investments, you may lose money by investing in the Fund. No performance information is available for the Fund because it has not yet been in operation for a full calendar year. December 8, 2014 2.69 <div style="display:none">~ http://www.alliancebernstein.com/role/ScheduleExpenseExampleAllianceBernsteinSelectUSEquityPortfolio column period compact * ~</div> No performance information is available for the Fund because it has not yet been in operation for a full calendar year. 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. For Class C shares, the CDSC is 0% after the first year. The Adviser has agreed to waive its management fees and/or to bear expenses of the Fund through December 8, 2014 to the extent necessary to prevent Total Fund Operating Expenses, on an annualized basis, from exceeding 1.60% on Class A shares; 2.30% on Class C shares; 1.30% on Advisor Class shares; 1.80% on Class R shares, 1.55% on Class K shares or 1.30% on Class I Shares (excluding acquired fund fees and expenses other than the advisory fees of any AllianceBernstein Mutual Funds in which the Fund may invest, interest expense, taxes, extraordinary expenses, and brokerage commissions and other transaction costs). Any fees waived and expenses borne by the Adviser may be reimbursed by the Fund until December 8, 2014, provided that no reimbursement payment will be made that would cause the Fund's Total Annual Fund Operating Expenses to exceed the Total Annual Fund Operating Expenses After Fee Waiver reflected in the table or cause the total of the payments to exceed the Fund's total initial offering expenses. Assuming redemption at the end of the period, a 1% CDSC would increase the expenses by approximately $100.
