AB VARIABLE PRODUCTS SERIES FUND, INC. -AB Balanced Wealth Strategy Portfolio (the Portfolio )

AB VARIABLE PRODUCTS SERIES FUND, INC. -AB Balanced Wealth Strategy Portfolio (the Portfolio ) Supplement dated February 8, 2018 to the Prospectuses and Summary Prospectuses dated May 1, 2017 for AB Variable Products Series Fund, Inc. (the Prospectuses ), offering Class A and Class B shares of AB Balanced Wealth Strategy Portfolio. * * * * * At meetings held on February 6-7, 2018, the Board of Directors approved the following changes to the Portfolio s principal strategies, which do not require stockholder approval and will take effect on or about May 1, 2018. The Principal Strategies section will be replaced with the following: The Portfolio invests in a portfolio of equity and fixed-income securities that is designed as a solution for investors who seek a moderate tilt toward equity returns but also want the risk diversification offered by fixed-income securities and the broad diversification of their equity risk across styles, capitalization ranges and geographic regions. Under normal circumstances, the Portfolio will invest at least 25% of its total assets in equity securities and at least 25% of its total assets in fixed-income securities with a goal of providing moderate upside potential without excessive volatility. The Portfolio also seeks exposure to real assets by investing in real estate-related equity securities (including real estate investment trusts, or REITs), natural resource equity securities and inflation-sensitive equity securities. The Portfolio pursues a global strategy, typically investing in securities of issuers located in the United States and in other countries throughout the world, including emerging market countries. The Adviser expects that the Portfolio will normally invest a greater percentage of its total assets in equity securities than in fixedincome securities, and will generally invest in equity securities both directly and through underlying investment companies advised by the Adviser ( Underlying Portfolios ). A significant portion of the Portfolio s assets are expected to be invested directly in U.S. large-cap equity securities, primarily common stocks, in accordance with the Adviser s U.S. Strategic Equities investment strategy ( U.S. Strategic Equities ). Under U.S. Strategic Equities, portfolio managers of the Adviser that specialize in various investment disciplines identify high-conviction large-cap equity securities based on their fundamental investment research for potential investment by the Portfolio. These securities are then assessed in terms of both this fundamental research and quantitative analysis in creating the equity portion of the Portfolio s portfolio. In applying the quantitative analysis, the Adviser considers a number of metrics that historically have provided some indication of favorable future returns, including metrics related to valuation, quality, investor behavior and corporate behavior. In addition, the Portfolio seeks to achieve exposure to international large-cap equity securities through investments in the International Strategic Equities Portfolio of Bernstein Fund, Inc. ( Bernstein International Strategic Equities Portfolio ) and the International Portfolio of Sanford C. Bernstein Fund, Inc. ( SCB International Portfolio ), each a registered investment company advised by the Adviser. The Portfolio also invests in other Underlying Portfolios to efficiently gain exposure to certain other types of equity securities, including small- and mid-cap and emerging market equity securities. The Adviser selects an Underlying Portfolio based on the segment of the equity market to which the Underlying Portfolio provides exposure, its investment philosophy, and how it complements and diversifies the Portfolio s overall portfolio. Bernstein International Strategic Equities Portfolio and SCB International Portfolio focus on investing in non-u.s. large-cap and mid-cap equity securities. Bernstein International Strategic Equities Portfolio follows a strategy similar to U.S. Strategic Equities, but in the international context. In managing SCB International Portfolio, the Adviser selects stocks by drawing on the capabilities of its separate investment teams specializing in different investment disciplines, including value, growth, stability and others. In selecting fixed-income investments, the Adviser may draw on the capabilities of separate investment teams that specialize in different areas that are generally defined by the maturity of the debt securities and/or their ratings, and which may include subspecialties (such as inflation-indexed securities). These fixed-income teams draw on the resources and expertise of the Adviser s internal fixed-income research staff, which includes over 50 dedicated fixed-income research analysts and economists. The Portfolio s fixed-income securities will primarily be investment grade debt securities, but are expected to include lower-rated securities ( junk bonds ) and preferred stock. The Portfolio expects to enter into derivative transactions, such as options, futures contracts, forwards and swaps. Derivatives may provide a more efficient and economical exposure to market segments than direct investments, and may also be a more efficient way to alter the Portfolio s exposure. The Portfolio may, for example, use credit default, interest rate and total return swaps to establish exposure to the fixed-income markets or particular fixed-income securities and, as noted below, may use currency derivatives to hedge foreign currency exposure. 8239(0318) Cat. No. 49856 Page 1 of 12

Fluctuations in currency exchange rates can have a dramatic impact on the returns of foreign securities. The Adviser may employ currency hedging strategies in the Portfolio or the Underlying Portfolios, including the use of currency-related derivatives, to seek to reduce currency risk in the Portfolio or the Underlying Portfolios, but it is not required to do so. The Adviser will generally employ currency hedging strategies more frequently in the fixed-income portion of the Portfolio than in the equity portion. The following risk factor will be added in the section Principal Risks : Investment in Other Investment Companies Risk: As with other investments, investments in other investment companies are subject to market and selection risk. In addition, Contractholders invested in the Portfolio bear both their proportionate share of expenses in the Portfolio (including management fees) and, indirectly, the expenses of the investment companies (to the extent these expenses are not waived or reimbursed by the Adviser). The following risk factor will replace Real Estate Risk in the section Principal Risks : Real Assets Risk: The Portfolio s investments in securities linked to real assets involve significant risks, including financial, operating, and competitive risks. Investments in securities linked to real assets expose the Portfolio to adverse macroeconomic conditions, such as a rise in interest rates or a downturn in the economy in which the asset is located. The Portfolio s investments in real estate securities have many of the same risks as direct ownership of real estate, including the risk that the value of real estate could decline due to a variety of factors that affect the real estate market generally. Investments in REITs may have additional risks. REITs are dependent on the capability of their managers, may have limited diversification, and could be significantly affected by changes in tax laws. * * * * * Effective immediately, the following table replaces the table under the heading Portfolio Managers in the summary section of the Prospectuses and reflects the persons responsible for the day-to-day management of the Portfolio s portfolio: Employee Length of Service Title Jess Gaspar Since February 2018 Senior Vice President of the Adviser Daniel J.

Neuberger Berman Equity Funds ( Equity Funds ) Supplement dated November 17, 2017 to the Summary Prospectus(es), Prospectus(es) and Statement of Additional Information of Neuberger Berman Focus Fund, Neuberger Berman Genesis Fund, Neuberger Berman Guardian Fund, Neuberger Berman International Equity Fund, Neuberger Berman Large Cap Value Fund, Neuberger Berman Mid Cap Growth Fund, Neuberger Berman Small Cap Growth Fund and Neuberger Berman Socially Responsive Fund The following change applies to the Summary Prospectus(es), Prospectus(es) and Statement of Additional Information for Neuberger Berman Focus Fund, Neuberger Berman Genesis Fund, Neuberger Berman Guardian Fund, Neuberger Berman International Equity Fund, Neuberger Berman Large Cap Value Fund, Neuberger Berman Mid Cap Growth Fund, Neuberger Berman Small Cap Growth Fund and Neuberger Berman Socially Responsive Fund (each a Fund and together, the Funds ): The Board of Trustees of Neuberger Berman Equity Funds ( Board ) has approved stock splits and reverse stock splits of the issued and outstanding shares of certain classes of each Fund (collectively, the Stock Split ). The Stock Split will be completed in two phases, with the first phase to include certain classes of Genesis Fund, Large Cap Value Fund, Mid Cap Growth Fund and Socially Responsive Fund, as outlined in the chart below, which will occur after the close of the business on December 8, 2017. Phase two of the Stock Split, for the remaining Funds, is expected to be completed in early 2018. Additional information, including the Stock Split ratios will be provided in advance of phase two of the Stock Split. As a result of the Stock Split, for each share of each affected class of each Fund a shareholder currently holds, the shareholder will receive a proportional number of the same class of shares of the respective Fund with the same aggregate dollar value. Thus, the total dollar value of an investment in a Fund(s) will be unchanged and each shareholder will continue to own the same percentage (by value) of the Fund immediately following the Stock Split as it did immediately prior to the Stock Split. The Stock Split will not be a taxable event, nor does it have an impact on any Fund s holdings or its performance. The Stock Split will be carried out in accordance with a Stock Split ratio calculated to result in net asset values per share ( NAVs ) that better align the share class prices of each of the Funds. The ratios, which are based on the NAVs as of November 8, 2017, are shown in the table below. The shares of each Fund impacted by the Stock Split will be offered, sold, and redeemed on a Stock Split-adjusted basis beginning on the first business day following the Stock Split. Genesis Fund, Large Cap Value Fund, Mid Cap Growth Fund and Socially Responsive Fund will affect the Stock Split after the close of the business on December 8, 2017. For the Funds that are carrying out the Stock Split on December 8, previously posted per share distributions estimated for 2017 will be adjusted in accordance with the Stock Split ratios outlined in the table below and updated with more recent income and capital gain distributions. Please visit www.nb.com for updated capital gain estimate information. Shareholders next account statement after the Stock Split is completed will reflect the Stock Split. Reason for the Stock Split The Board approved the Stock Split in order to bring the NAVs of the classes of each Fund into better alignment with one another. The Splits are designed to reduce the variance between the NAVs in order for shares of each respective class of each respective Fund to have approximately the same NAV. This is intended to reduce marketplace confusion and bring greater uniformity to the ratio of capital gains to the NAVs across the classes of each affected fund. 8239(0318) Page 8 of 12

This undertaking lasts until 12/31/2020 and may not be terminated during its term without the consent of the Board of Trustees. The Fund has agreed that Class S will repay the Manager for fees and expenses waived or reimbursed for that class provided that repayment does not cause annual operating expense to exceed 1.10% of its average net assets. Any such repayment must be made within three years after the year in which the Manager incurred the expense. Expense Example The expense example can help you compare costs among mutual funds. The example assumes that you invested $10,000 for the periods shown, that you redeemed all of your shares at the end of those periods, that the Fund earned a hypothetical 5% total return each year, and that the Fund s expenses were those in the table.
