ALLIANCEBERNSTEIN VPS SMALL/MID CAP VALUE PORTFOLIO
INVESTMENT OBJECTIVE
The Portfolio's investment objective is long-term growth of capital.
FEES AND EXPENSES OF THE PORTFOLIO
This table describes the fees and expenses that you may pay if you buy and hold shares of the Portfolio. The operating expenses information below is designed to assist Contractholders of variable products that invest in the Portfolio in understanding the fees and expenses that they may pay as an investor. Because the information does not reflect deductions at the separate account level or contract level for any charges that may be incurred under a contract, Contractholders that invest in the Portfolio should refer to the variable contract prospectus for a description of fees and expenses that apply to Contractholders. Inclusion of these charges would increase the fees and expenses provided below.

EXAMPLES
The Examples are intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Examples assume that you invest $10,000 in the Portfolio 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 Portfolio's operating expenses stay the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER
The Portfolio 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. These transaction costs, which are not reflected in the Annual Portfolio Operating Expenses or in the Examples, affect the Portfolio's performance. During the most recent fiscal year, the Portfolio's portfolio turnover rate was 70% of the average value of its portfolio.
PRINCIPAL STRATEGIES

The Portfolio invests primarily in a diversified portfolio of equity securities of small - to mid-capitalization U.S. companies, generally representing 60 to 125 companies. Under normal circumstances, the Portfolio invests at least 80% of its net assets in securities of small- to mid-capitalization companies. For purposes of this policy, small- to mid-capitalization companies are those that, at the time of investment, fall within the capitalization range between the smallest company in the Russell 2500(R) Value Index and the greater of $5 billion or the market capitalization of the largest company in the Russell 2500(R) Value Index.

Because the Portfolio's definition of small - to mid-capitalization companies is dynamic, the lower and upper limits on market capitalization will change with the markets. As of December 31, 2011, there were approximately 1,693 small- to mid-capitalization companies, representing a market capitalization range from approximately $37 million to approximately $7.463 billion.

The Portfolio invests in companies that are determined by the Adviser to be undervalued, using the Adviser's fundamental value approach. In selecting securities for the Portfolio's portfolio, the Adviser uses its fundamental and quantitative research to identify companies whose long-term earnings power is not reflected in the current market price of their securities.

In selecting securities for the Portfolio's portfolio, the Adviser looks for companies with attractive valuation (for example, with low price to book ratios) and compelling success factors (for example, momentum and return on equity). The Adviser then uses this information to calculate an expected return. Returns and rankings are updated on a daily basis. The rankings are used to determine prospective candidates for further fundamental research and, subsequently, possible addition to the portfolio. Typically, the Adviser's fundamental research analysts focus their research on the most attractive 20% of the universe.

The Adviser typically projects a company's financial performance over a full economic cycle, including a trough and a peak, within the context of forecasts for real economic growth, inflation and interest rate changes. The Adviser focuses on the valuation implied by the current price, relative to the earnings the company will be generating five years from now, or "normalized" earnings, assuming average mid-economic cycle growth for the fifth year.

The Portfolio's management team and other senior investment professionals work in close collaboration to weigh each investment opportunity identified by the research staff relative to the entire portfolio and determine the timing and position size for purchases and sales. Analysts remain responsible for monitoring new developments that would affect the securities they cover. The team will generally sell a security when it no longer meets appropriate valuation criteria, although sales may be delayed when positive return trends are favorable. Typically, growth in the size of a company's market capitalization relative to other domestically traded companies will not cause the Portfolio to dispose of the security.

The Adviser seeks to manage overall portfolio volatility relative to the universe of companies that comprise the lowest 20% of the total U.S. market capitalization by favoring promising securities that offer the best balance between return and targeted risk. At times, the Portfolio may favor or disfavor a particular sector compared to that universe of companies. The Portfolio may invest significantly in companies involved in certain sectors that constitute a material portion of the universe of small- and mid-capitalization companies, such as financial services and consumer services.

The Portfolio may enter into derivatives transactions, such as options, futures, forwards and swaps. The Portfolio may use options strategies involving the purchase and/or writing of various combinations of call and/or put options, including on individual securities and stock indexes, futures contracts (including futures contracts on individual securities and stock indexes) or shares of exchange-traded funds. These transactions may be used, for example, to earn extra income, to adjust exposure to individual securities or markets, or to protect all or a portion of the Portfolio's portfolio from a decline in value, sometimes within certain ranges.

The Portfolio may invest in securities issued by non-U.S. companies.

PRINCIPAL RISKS

. MARKET RISK: The value of the Portfolio'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 that affect large portions of the market. It includes the risk that a particular style of investing, such as value, may underperform the market generally.

. CAPITALIZATION RISK: Investments in small- and mid-capitalization companies may be more volatile than investments in large-capitalization companies. Investments in small-capitalization companies may have additional risks because these companies have limited product lines, markets or financial resources.

. 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 less liquid due to adverse market, economic, political, regulatory or other factors.

. CURRENCY RISK: Fluctuations in currency exchange rates may negatively affect the value of the Portfolio's investments or reduce its returns.

. DERIVATIVES RISK: Derivatives may be illiquid, difficult to price, and leveraged so that small changes may produce disproportionate losses for the Portfolio, and may be subject to counterparty risk to a greater degree than more traditional investments.

. MANAGEMENT RISK: The Portfolio 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 Portfolio, but there is no guarantee that its techniques will produce the intended results.

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

BAR CHART AND PERFORMANCE INFORMATION

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

. how the Portfolio's performance changed from year to year over ten years; and

. how the Portfolio's average annual returns for one, five and ten years compare to those of a broad-based securities market index.

The performance information does not take into account separate account charges. If separate account charges were included, an investor's return would be lower. The Portfolio's past performance, of course, does not necessarily indicate how it will perform in the future.
