Beginning January 1, 2021, as permitted by new regulations adopted by the Securities and Exchange Commission, the Portfolio’s annual and semi-annual shareholder reports will no longer be sent by mail, unless you specifically request paper copies of the reports. Instead, the reports will be made available on a website, and you will be notified by mail each time a report is posted and provided with a website address to access the report.

If you already elected to receive shareholder reports electronically, you will not be affected by this change and you need not take any action. You may elect to receive shareholder reports and other communications from the Portfolio electronically at any time by contacting your financial intermediary (such as a broker-dealer or bank) or, if you are a direct investor, by calling the Portfolio at (212) 486-5800.

You may elect to receive all future reports in paper form free of charge. If you invest through a financial intermediary, you can contact your financial intermediary to request that you continue to receive paper copies of your shareholder reports; if you invest directly with the Portfolio, you can call the Portfolio at (212) 486-5800. Your election to receive reports in paper form will apply to all funds held in your account with your financial intermediary or, if you invest directly, to all AB Mutual Funds you hold.

INVESTMENT OBJECTIVE:

The Portfolio’s investment objective is to provide safety of principal and a moderate rate of income that is subject to taxes.

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 as reflected in the Examples would be:

	Short Duration Plus Class
After 1 Year	$	57
After 3 Years	$	179
After 5 Years	$	313
After 10 Years	$	701

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 and may result in higher taxes when Portfolio shares are held in a taxable account.

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 39% of the average value of its portfolio.

PRINCIPAL STRATEGIES:

The Portfolio invests at least 80% of its total assets in securities rated A or better by national rating agencies (or, if unrated, determined by AllianceBernstein L.P., the Portfolio’s investment manager (the “Manager”), to be of comparable quality) and comparably rated commercial paper and notes. Many types of securities may be purchased by the Portfolio, including corporate bonds, notes, U.S. government and agency securities, asset-backed securities, mortgage-related securities, inflation-protected securities, bank loan debt and preferred stock, as well as others. The Portfolio may also invest up to 20% of its total assets in fixed-income foreign securities in developed or emerging-market countries.

The Portfolio may use derivatives, such as options, futures contracts, forward contracts and swaps.

The Portfolio may invest up to 20% of its total assets in fixed-income securities rated BB or B by national rating agencies, which are not investment-grade (commonly known as “junk bonds”).

In managing the Portfolio, the Manager may use interest rate forecasting to estimate an appropriate level of interest rate risk at a given time.

The Portfolio seeks to maintain an effective duration of one to three years under normal market conditions. Duration is a measure that relates the expected price volatility of a security to changes in interest rates. The duration of a debt security is the weighted average term to maturity, expressed in years, of the present value of all future cash flows, including coupon payments and principal repayments.

Within the range described above, the Manager may moderately shorten the average duration of the Portfolio when it expects interest rates to rise and moderately lengthen average duration when it anticipates that interest rates will fall.

The Manager selects securities for purchase or sale based on its assessment of the securities’ risk and return characteristics as well as the securities’ impact on the overall risk and return characteristics of the Portfolio. In making this assessment, the Manager takes into account various factors including the credit quality and sensitivity to interest rates of the securities under consideration and of the Portfolio’s other holdings.

The Portfolio may enter into foreign currency transactions on a spot (i.e., cash) basis or through the use of derivatives transactions, such as forward currency exchange contracts, currency futures and options thereon, and options on currencies. An appropriate hedge of currency exposure resulting from the Portfolio’s securities positions may not be available or cost effective, or the Manager may determine not to hedge the positions, possibly even under market conditions where doing so could benefit the Portfolio.

PRINCIPAL RISKS:

The share price of the Portfolio will fluctuate and you may lose money. There is no guarantee that the Portfolio will achieve its investment objective.

• Interest Rate Risk: This is the risk that changes in interest rates will affect the value of the Portfolio’s investments in fixed-income debt securities such as bonds and notes. When interest rates rise, the value of the Portfolio’s existing investments tends to

S-2

fall and this decrease in value may not be offset by higher income from new investments. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations. A general rise in interest rates may cause investors to move out of fixed-income securities on a large scale, which could adversely affect the price and liquidity of fixed-income securities and could also result in increased redemptions from a portfolio that invests largely in fixed-income securities.

• Credit Risk: This is the risk that the issuer or the guarantor of a debt security, or the counterparty to a derivatives or other contract, will be unable or unwilling to make timely principal and/or interest payments, or to otherwise honor its obligations. The issuer or guarantor may default, potentially causing a loss of the full principal amount of a security and accrued interest. The degree of risk for a particular security may be reflected in its credit rating. The credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations, making credit risk greater for medium-quality and lower-rated debt securities. Lower-rated debt securities and similar unrated securities (commonly known as “junk bonds”) have speculative elements or are predominantly speculative credit risks. At times when credit risk is perceived to be greater, credit “spreads” (i.e., the difference between the yields on lower quality securities and the yields on higher quality securities) may get larger or “widen”. As a result, the values of the lower quality securities may go down more and they may become harder to sell.

• Duration Risk: The duration of a fixed-income security may be shorter than or equal to full maturity of the fixed-income security. Fixed-income securities with longer durations have more interest rate risk and will decrease in price as interest rates rise. Securities that have final maturities longer than their durations may be affected by increased credit spreads to a far greater degree than their durations would suggest, because they are exposed to credit risk until final maturity.

• Inflation Risk: This is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the value of the Portfolio’s assets can decline as can the value of the Portfolio’s distributions. This risk is significantly greater for fixed-income securities with longer maturities.

• Inflation-Protected Securities Risk: The terms of inflation-protected securities provide for the coupon and/or maturity value to be adjusted based on changes in an inflation index. Decreases in the inflation rate or in investors’ expectations about inflation could cause these securities to underperform non-inflation-adjusted securities on a total-return basis. In addition, there can be no assurance that the relevant inflation index will accurately measure the rate of inflation, in which case the securities may not work as intended. These securities may be more difficult to trade or dispose of than other types of securities.

• Foreign (Non-U.S.) Securities Risk: Investments in foreign securities entail significant risks in addition to those customarily associated with investing in U.S. securities. These risks include risks related to adverse market, economic, political and regulatory factors and social instability, all of which could disrupt the financial markets in which the Portfolio invests and adversely affect the value of the Portfolio’s assets.

• Emerging Markets Securities Risk: The risks of investing in foreign (non-U.S.) securities are heightened with respect to issuers in emerging-market countries because the markets are less developed and less liquid and there may be a greater amount of economic, political and social uncertainty, and these risks are even more pronounced in “frontier” markets, which are investable markets with lower total market capitalization and liquidity than the more developed emerging markets. In addition, the value of the Portfolio’s investments may decline because of factors such as unfavorable or unsuccessful government actions and reduction of government or central bank support.

• Derivatives Risk: The Portfolio may use derivatives as direct investments to earn income, enhance return and broaden portfolio diversification, which entail greater risk than if used solely for hedging purposes. In addition to other risks such as the credit risk of the counterparty, derivatives involve the risk that changes in the value of the derivative may not correlate with relevant assets, rates or indices. Derivatives may be difficult to price or unwind, and small changes may produce disproportionate losses for the Portfolio. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. Assets required to be set aside or posted to cover or secure derivatives positions may themselves go down in value, and these collateral and other requirements may limit investment flexibility. Some derivatives involve leverage, which can make the Portfolio more volatile and can compound other risks. Derivatives, especially over-the-counter derivatives, are also subject to counterparty risk. Use of derivatives may have different tax consequences for the Portfolio than an investment in the underlying asset or index, and such differences may affect the amount, timing and character of income distributed to shareholders. The U.S. government and certain foreign governments have adopted regulations governing derivatives markets, including mandatory clearing of certain derivatives and may impose additional regulations governing margin, reporting and registration requirements. The ultimate impact of the regulations remains unclear. Additional regulation may make derivatives more costly, limit their availability or utility, otherwise adversely affect their performance, or disrupt markets.

• Mortgage-Related and Asset-Related Securities Risk: Mortgage- and asset-related securities represent interests in “pools” of mortgages or other assets, including consumer loans or receivables held in trust. Mortgage- and asset-related securities are subject to credit, interest rate, prepayment and extension risks. These securities also are subject to risk of default on the underlying

S-3

mortgage or asset, particularly during periods of economic downturn. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain mortgage-related securities.

• Prepayment and Extension Risk: Prepayment risk is the risk that a loan, bond or other security might be called or otherwise converted, prepaid or redeemed before maturity. If this happens, particularly during a time of declining interest rates or credit spreads, the Portfolio will not benefit from the rise in market price that normally accompanies a decline in interest rates, and may not be able to invest the proceeds in securities providing as much income, resulting in a lower yield to the Portfolio. Conversely, extension risk is the risk that as interest rates rise or spreads widen, payments of securities may occur more slowly than anticipated by the market. If this happens, the values of these securities may go down because their interest rates are lower than current market rates and they remain outstanding longer than anticipated.

• Subordination Risk: The Portfolio may invest in securities that are subordinated to more senior securities of an issuer, or which represent interests in pools of such subordinated securities. Subordinated securities will be disproportionately affected by a default or even a perceived decline in creditworthiness of the issuer. Subordinated securities are more likely to suffer a credit loss than non-subordinated securities of the same issuer, any loss incurred by the subordinated securities is likely to be proportionately greater, and any recovery of interest or principal may take more time.

• Management Risk: The Portfolio is subject to management risk because it is an actively managed investment portfolio. The Manager will apply its investment techniques and risk analyses in making investment decisions for the Portfolio, but these techniques, analyses and decisions may not work as intended or may not produce the desired results, and may, during certain periods, result in increased volatility for the Portfolio or cause the value of the Portfolio’s shares to go down. In some cases, derivatives and other investment techniques may be unavailable, or the Manager may determine not to use them, possibly even under market conditions where their use could benefit the Portfolio. 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. In addition, the Manager may change the Portfolio’s investment strategies or policies from time to time. Those changes may not lead to the results intended by the Manager and could have an adverse effect on the value or performance of the Portfolio.

• Illiquid Investments Risk: Illiquid investments risk exists when particular investments are difficult to purchase or sell, possibly preventing the Portfolio from purchasing or selling these securities at an advantageous price. Over recent years, regulatory changes have led to reduced liquidity in the marketplace, and the capacity of dealers to make markets in fixed-income securities has been outpaced by the growth in the size of the fixed-income markets. Illiquid investments risk may be magnified in a rising interest rate environment, where the value and liquidity of fixed-income securities generally go down. Illiquid securities may also be difficult to value.

• Redemption Risk: The Portfolio may experience heavy redemptions that could cause the Portfolio to liquidate its assets at inopportune times or unfavorable prices or increase or accelerate taxable gains or transaction costs and may negatively affect the Portfolio’s net asset value, or performance, which could cause the value of your investment to decline. Redemption risk is heightened during periods of overall market turmoil.

• Foreign Currency Risk: This is the risk that changes in foreign (non-U.S.) currency exchange rates may negatively affect the value of the Portfolio’s investments or reduce the returns of the Portfolio. For example, the value of the Portfolio’s investments in foreign securities and foreign currency positions may decrease if the U.S. Dollar is strong (i.e., gaining value relative to other currencies) and other currencies are weak (i.e., losing value relative to the U.S. Dollar).

• Actions by a Few Major Investors: In certain countries, volatility may be heightened by actions of a few major investors. For example, substantial increases or decreases in cash flows of mutual funds investing in these markets could significantly affect local securities prices and, therefore, share prices of the Portfolio.

• Market Risk: The Portfolio is subject to market risk, which is the risk that bond prices in general or in particular countries or sectors may decline over short or extended periods. In the past decade, financial markets in the United States, Europe and elsewhere have experienced increased volatility, decreased liquidity and heightened uncertainty. These market conditions may recur from time to time and have an adverse impact on various securities markets. Certain governments and central banks have provided significant support to financial markets, including by buying stocks and through other market interventions. Further governmental or central bank actions, including interest rate increases or decreases, could negatively affect financial markets generally, increase market volatility and reduce the value and liquidity of securities in which the Portfolio invests.

The United Kingdom (the “U.K.”) voted to withdraw from the European Union (the “EU”) in 2016. A draft withdrawal agreement containing transitional arrangements and a Political Declaration setting out the agreed negotiating parameters for a future trading relationship were published in October 2019. The outcome of negotiations in respect of the future trading relationship remains uncertain. The U.K. will leave the EU on January 31, 2020 subject to a transition period ending December 31, 2020. The European Union (Withdrawal Agreement) Act 2020, which sets out the arrangements for the U.K.’s withdrawal from the EU, became law in the U.K. on January 23, 2020. The uncertainty surrounding the effect of the U.K. ceasing to be a member

S-4

of the EU, including the uncertainty in relation to the legal and regulatory framework that will apply to the U.K. and its relationship with the remaining members of the EU (including, in relation to trade) after the end of the transitional period has caused and is likely to continue to cause increased economic volatility and market uncertainty globally.

The United States and its trading partners are periodically involved in disputes over trade, which may result in tariffs on various categories of goods imported from the other country. Trade disputes, particularly prolonged disputes, may adversely affect the economies of the United States and its trading partners, as well as the companies directly or indirectly affected by the dispute and financial markets generally, and thus may adversely affect the value of the Portfolio’s assets. In addition, policy and legislative changes in the United States and in other countries are affecting many aspects of financial regulation, and may in some instances contribute to decreased liquidity and increased volatility in the financial markets. The impact of these changes, and the practical implications for market participants, may not be fully known for some time.

Economies and financial markets throughout the world are becoming increasingly interconnected. Economic, financial or political events, trading and tariff arrangements, terrorism, natural disasters and other circumstances in one country or region could have profound impacts on global economies or markets. As a result, whether or not the Portfolio invests in securities of issuers located in or with significant exposure to countries experiencing economic and financial difficulties, the value and liquidity of the Portfolio’s investments may be negatively affected.

• Lower-rated Securities Risk: Lower-rated securities, or junk bonds/high-yield securities, are subject to greater risk of loss of principal and interest and greater market risk than higher-rated securities. The capacity of issuers of lower-rated securities to pay interest and repay principal is more likely to weaken than is that of issuers of higher-rated securities in times of deteriorating economic conditions or rising interest rates.

• Riskier than a Money-Market Fund: Although the Portfolio maintains a short overall duration, it invests in securities with longer maturities and in some cases lower quality than the assets of the type of mutual fund known as a money-market fund. The risk of a decline in the market value of the Portfolio is greater than for a money-market fund since the credit quality of the Portfolio’s securities may be lower and the effective duration of the Portfolio will be longer.
