ALLIANCEBERNSTEIN VPS REAL ESTATE INVESTMENT PORTFOLIO
--------------------------------------------------------------------------------

INVESTMENT OBJECTIVE
The Portfolio's investment objective is total return from long-term growth of
capital and income.

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:

----------------------
After 1 Year    $  127
After 3 Years   $  397
After 5 Years   $  686
After 10 Years  $1,511
----------------------

PORTFOLIO TURNOVER
The Portfolio pays transactions 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 94% of the average value of its
portfolio.

PRINCIPAL STRATEGIES
Under normal circumstances, the Portfolio invests at least 80% of its net
assets in the equity securities of real estate investment trusts, or REITs, and
other real estate industry companies, such as real estate operating companies,
or REOCs. The Portfolio invests in real estate companies that the Adviser
believes have strong property fundamentals and management teams. The Portfolio
seeks to invest in real estate companies whose underlying portfolios are
diversified geographically and by property type.

The Portfolio's investment policies emphasize investment in companies
determined by the Adviser to be undervalued relative to their peers, using a
fundamental value approach. In selecting real estate equity securities, the
Adviser's research and investment process seeks to identify those companies
where the magnitude and growth of cash flow streams have not been appropriately
reflected in the price of the security. These securities may trade at a more
attractive valuation than others that may have similar overall fundamentals.
The Adviser's fundamental research efforts are focused on forecasting the
short- and long-term normalized cash generation capability of real estate
companies by isolating supply and demand for property types in local markets,
determining the replacement value of properties, assessing future development
opportunities, and normalizing capital structures of real estate companies.

The Portfolio may invest in mortgage-backed securities, which are securities
that directly or indirectly represent participations in, or are collateralized
by and payable from, mortgage loans secured by real property. These securities
include mortgage pass-through certificates, real estate mortgage investment
conduit certificates, or REMICs, and collateralized mortgage obligations, or
CMOs. The Portfolio also may invest in short-term investment grade debt
securities and other fixed-income securities.

The Portfolio invests in equity securities that include common stock, shares of
beneficial interests of REITs and securities with common stock characteristics,
such as preferred stock or convertible securities ("real estate equity
securities"). The Portfolio may invest in foreign securities and enter into
forward commitments and standby commitment agreements. The Portfolio may enter
into derivatives transactions, including options, futures, forwards and swap
agreements.

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.

.  INDUSTRY/SECTOR RISK: Investments in a particular industry or group of
   related industries may have more risk because market or economic factors
   affecting that industry could have a significant effect on the value of the
   Portfolio's investments.

.  INTEREST RATE RISK: Changes in interest rates will affect the value of
   investments in fixed-income securities. When interest rates rise, the value
   of investments in fixed-income securities tend to 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.

.  CREDIT RISK: An issuer or guarantor of a fixed-income security, or the
   counterparty to a derivatives or other contract, may be unable or unwilling
   to make timely payments of interest or principal, or to otherwise honor its
   obligations. The issuer or guarantor may default causing a loss of the full
   principal amount of a security. The degree of risk for a particular security
   may be reflected in its credit rating. There is the possibility that 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.

.  REAL ESTATE RISK: The Portfolio's investments in the real estate market 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.

.  PREPAYMENT RISK: The value of mortgage-related or asset-backed securities
   may be particularly sensitive to changes in prevailing interest rates. Early
   payments of principal on some mortgage-related securities may occur during
   periods of falling mortgage interest rates and expose the Portfolio to a
   lower rate of return upon reinvestment of principal. Early payments
   associated with mortgage-related securities cause these securities to
   experience significantly greater price and yield volatility than is
   experienced by traditional fixed-income securities. During periods of rising
   interest rates, a reduction in prepayments may increase the effective life
   of mortgage-related securities, subjecting them to greater risk of decline
   in market value in response to rising interest rates. If the life of a
   mortgage-related security is inaccurately predicted, the Portfolio may not
   be able to realize the rate of return it expected.

.  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.

.  FOREIGN (NON-U.S.) RISK: Investment 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.

.  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.

You may obtain updated performance information on the Portfolio's website at
www.AllianceBernstein.com (click on "Pricing & Performance").

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.

ADDITIONAL INFORMATION ABOUT THE PORTFOLIO'S RISKS AND INVESTMENTS
--------------------------------------------------------------------------------

This section of the Prospectus provides additional information about the
Portfolio's investment practices and risks. Most of these investment practices
are discretionary, which means that the Adviser may or may not decide to use
them. This Prospectus does not describe all of the Portfolio's investment
practices and additional descriptions of the Portfolio's strategies,
investments, and risks can be found in the Fund's Statement of Additional
Information ("SAI").

DERIVATIVES
The Portfolio may, but is not required to, use derivatives for risk management
purposes or as part of its investment strategies. Derivatives are financial
contracts whose value depends on, or is derived from, the value of an
underlying asset, reference rate or index. The Portfolio may use derivatives to
earn income and enhance returns, to hedge or adjust the risk profile of a
portfolio, to replace more traditional direct investments and to obtain
exposure to otherwise inaccessible markets.

There are four principal types of derivatives, including options, futures,
forwards and swaps, which are described below. Derivatives may be
(i) standardized, exchange-traded contracts or (ii) customized, privately
negotiated contracts. Exchange-traded derivatives tend to be more liquid and
subject to less credit risk than those that are privately negotiated.

The Portfolio's use of derivatives may involve risks that are different from,
or possibly greater than, the risks associated with investing directly in
securities or other more traditional instruments. These risks include the risk
that the value of a derivative instrument may not correlate perfectly, or at
all, with the value of the assets, reference rates, or indices that they are
designed to track. Other risks include: the possible absence of a liquid
secondary market for a particular instrument and possible exchange-imposed
price fluctuation limits, either of which may make it difficult or impossible
to close out a position when desired; and the risk that the counterparty will
not perform its obligations. Certain derivatives may have a leverage component
and involve leverage risk. Adverse changes in the value or level of the
underlying asset, note or index can result in a loss substantially greater than
the Portfolio's investment (in some cases, the potential loss is unlimited).

The Portfolio's investments in derivatives may include, but are not limited to,
the following:

.  FORWARD CONTRACTS. A forward contract is a customized, privately negotiated
   agreement for one party to buy, and the other party to sell, a specific
   quantity of an underlying commodity or other tangible asset for an agreed
   upon price at a future date. A forward contract is either settled by
   physical delivery of the commodity or tangible asset to an agreed-upon
   location at a future date, rolled forward into a new forward contract or, in
   the case of a non-deliverable forward, by a cash payment at maturity. The
   Portfolio's investments in forward contracts may include the following:

 - Forward Currency Exchange Contracts. The Portfolio may purchase or sell
   forward currency exchange contracts for hedging purposes to minimize the
   risk from adverse changes in the relationship between the U.S. Dollar and
   other currencies or for non-hedging purposes as a means of making direct
   investments in foreign currencies, as described below under "Currency
   Transactions". The Portfolio, for example, may enter into a forward contract
   as a transaction hedge (to "lock in" the U.S. Dollar price of a non-U.S.
   Dollar security), as a position hedge (to protect the value of securities
   the Portfolio owns that are denominated in a foreign currency against
   substantial changes in the value of the foreign currency) or as a
   cross-hedge (to protect the value of securities the Portfolio owns that are
   denominated in a foreign currency against substantial changes in the value
   of that foreign currency by entering into a forward contract for a different
   foreign currency that is expected to change in the same direction as the
   currency in which the securities are denominated).

.  FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS. A futures contract is an
   agreement that obligates the buyer to buy and the seller to sell a specified
   quantity of an underlying asset (or settle for cash the value of a contract
   based on an underlying asset, rate or index) at a specific price on the
   contract maturity date. Options on futures contracts are options that call
   for the delivery of futures contracts upon exercise. The Portfolio may
   purchase or sell futures contracts and options thereon to hedge against
   changes in interest rates, securities (through index futures or options) or
   currencies. The Portfolio may also purchase or sell futures contracts for
   foreign currencies or options thereon for non-hedging purposes as a means of
   making direct investments in foreign currencies, as described below under
   "Currency Transactions".

.  OPTIONS. An option is an agreement that, for a premium payment or fee, gives
   the option holder (the buyer) the right but not the obligation to buy (a
   "call option") or sell (a "put option") the underlying asset (or settle for
   cash an amount based on an underlying asset, rate or index) at a specified
   price (the exercise price) during a period of time or on a specified date.
   Investments in options are considered speculative. The Portfolio may lose
   the premium paid for them if the price of the underlying security or other
   asset decreased or remained the same (in the case of a call option) or
   increased or remained the same (in the case of a put option). If a put or
   call option purchased by the Portfolio were permitted to expire without
   being sold or exercised, its premium would represent a loss to the
   Portfolio. The Portfolio's investments in options include the following:

 - Options on Foreign Currencies. The Portfolio may invest in options on
   foreign currencies that are privately negotiated or traded on U.S. or
   foreign exchanges for hedging purposes to protect against declines in the
   U.S. Dollar value of foreign currency denominated securities held by the
   Portfolio and against increases in the U.S. Dollar cost of securities to be
   acquired. The purchase of an option on

8



   a foreign currency may constitute an effective hedge against fluctuations in
   exchange rates, although if rates move adversely, the Portfolio may forfeit
   the entire amount of the premium plus related transaction costs. The
   Portfolio may also invest in options on foreign currencies for non-hedging
   purposes as a means of making direct investments in foreign currencies, as
   described below under "Currency Transactions".

.  SWAP TRANSACTIONS. A swap is a customized, privately negotiated agreement
   that obligates two parties to exchange a series of cash flows at specified
   intervals (payment dates) based upon, or calculated by, reference to changes
   in specified prices or rates (interest rates in the case of interest rate
   swaps, currency exchange rates in the case of currency swaps) for a
   specified amount of an underlying asset (the "notional" principal amount).
   Except for currency swaps, the notional principal amount is used solely to
   calculate the payment stream, but is not exchanged. Swaps are entered into
   on a net basis (i.e., the two payment streams are netted out, with the
   Portfolio receiving or paying, as the case may be, only the net amount of
   the two payments). The Portfolio's investments in swap transactions include
   the following:

 - Credit Default Swap Agreements. The "buyer" in a credit default swap
   contract is obligated to pay the "seller" a periodic stream of payments over
   the term of the contract in return for a contingent payment upon the
   occurrence of a credit event with respect to an underlying reference
   obligation. Generally, a credit event means bankruptcy, failure to pay,
   obligation acceleration or modified restructuring. The Portfolio may be
   either the buyer or seller in the transaction. If the Portfolio is a seller,
   the Portfolio receives a fixed rate of income throughout the term of the
   contract, which typically is between one month and five years, provided that
   no credit event occurs. If a credit event occurs, the Portfolio typically
   must pay the contingent payment to the buyer, which is typically the "par
   value" (full notional value) of the reference obligation. The contingent
   payment may be a cash payment or by physical delivery of the reference
   obligation in return for payment of the face amount of the obligation. The
   value of the reference obligation received by the Portfolio coupled with the
   periodic payments previously received may be less than the full notional
   value it pays to the buyer, resulting in a loss of value to the Portfolio.
   If the Portfolio is a buyer and no credit event occurs, the Portfolio will
   lose its periodic stream of payments over the term of the contract. However,
   if a credit event occurs, the buyer typically receives full notional value
   for a reference obligation that may have little or no value.

   Credit default swaps may involve greater risks than if the Portfolio had
   invested in the reference obligation directly. Credit default swaps are
   subject to general market risk, liquidity risk and credit risk.

.  OTHER DERIVATIVES AND STRATEGIES.

 - Currency Transactions. The Portfolio may invest in non-U.S. Dollar
   securities on a currency hedged or unhedged basis. The Adviser may actively
   manage the Portfolio's currency exposures and may seek investment
   opportunities by taking long or short positions in currencies through the
   use of currency-related derivatives, including forward currency exchange
   contracts, futures and options on futures, swaps and options. The Adviser
   may enter into transactions for investment opportunities when it anticipates
   that a foreign currency will appreciate or depreciate in value but
   securities denominated in that currency are not held by the Portfolio and do
   not present attractive investment opportunities. Such transactions may also
   be used when the Adviser believes that it may be more efficient than a
   direct investment in a foreign currency-denominated security. The Portfolio
   may also conduct currency exchange contracts on a spot basis (i.e., for cash
   at the spot rate prevailing in the currency exchange market for buying or
   selling currencies).

 - Synthetic Foreign Equity Securities. The Portfolio may invest in different
   types of derivatives generally referred to as synthetic foreign equity
   securities. These securities may include international warrants or local
   access products. International warrants are financial instruments issued by
   banks or other financial institutions, which may or may not be traded on a
   foreign exchange. International warrants are a form of derivative security
   that may give holders the right to buy or sell an underlying security or a
   basket of securities representing an index from or to the issuer of the
   warrant for a particular price or may entitle holders to receive a cash
   payment relating to the value of the underlying security or index, in each
   case upon exercise by the Portfolio. Local access products are similar to
   options in that they are exercisable by the holder for an underlying
   security or a cash payment based upon the value of that security, but are
   generally exercisable over a longer term than typical options. These types
   of instruments may be American style, which means that they can be exercised
   at any time on or before the expiration date of the international warrant,
   or European style, which means that they may be exercised only on the
   expiration date.

   Other types of synthetic foreign equity securities in which the Portfolio
   may invest include covered warrants and low exercise price warrants. Covered
   warrants entitle the holder to purchase from the issuer, typically a
   financial institution, upon exercise, common stock of an international
   company or receive a cash payment (generally in U.S. Dollars). The issuer of
   the covered warrants usually owns the underlying security or has a
   mechanism, such as owning equity warrants on the underlying securities,
   through which it can obtain the underlying securities. The cash payment is
   calculated according to a predetermined formula, which is generally based on
   the difference between the value of the underlying security on the date of
   exercise and the strike price. Low exercise price warrants are warrants with
   an exercise price that is very low relative to the market price of the
   underlying instrument at the time of issue (e.g., one cent or less). The

                                                                             9



   buyer of a low exercise price warrant effectively pays the full value of the
   underlying common stock at the outset. In the case of any exercise of
   warrants, there may be a time delay between the time a holder of warrants
   gives instructions to exercise and the time the price of the common stock
   relating to exercise or the settlement date is determined, during which time
   the price of the underlying security could change significantly. In
   addition, the exercise or settlement date of the warrants may be affected by
   certain market disruption events, such as difficulties relating to the
   exchange of a local currency into U.S. Dollars, the imposition of capital
   controls by a local jurisdiction or changes in the laws relating to foreign
   investments. These events could lead to a change in the exercise date or
   settlement currency of the warrants, or postponement of the settlement date.
   In some cases, if the market disruption events continue for a certain period
   of time, the warrants may become worthless resulting in a total loss of the
   purchase price of the warrants.

   The Portfolio will acquire synthetic foreign equity securities issued by
   entities deemed to be creditworthy by the Adviser, which will monitor the
   creditworthiness of the issuers on an ongoing basis. Investments in these
   instruments involve the risk that the issuer of the instrument may default
   on its obligation to deliver the underlying security or cash in lieu
   thereof. These instruments may also be subject to liquidity risk because
   there may be a limited secondary market for trading the warrants. They are
   also subject, like other investments in foreign securities, to foreign
   (non-U.S.) risk and currency risk.

CONVERTIBLE SECURITIES
Prior to conversion, convertible securities have the same general
characteristics as non-convertible debt securities which generally provide a
stable stream of income with generally higher yields than those of equity
securities of the same or similar issuers. The price of a convertible security
will normally vary with changes in the price of the underlying equity security,
although the higher yield tends to make the convertible security less volatile
than the underlying equity security. As with debt securities, the market value
of convertible securities tends to decrease as interest rates rise and increase
as interest rates decline. While convertible securities generally offer lower
interest or dividend yields than non-convertible debt securities of similar
quality, they offer investors the potential to benefit from increases in the
market prices of the underlying common stock. Convertible debt securities that
are rated Baa3 or lower by Moody's or BBB- or lower by S&P or Fitch and
comparable unrated securities may share some or all of the risks of debt
securities with those ratings.

FORWARD COMMITMENTS
Forward commitments for the purchase or sale of securities may include
purchases on a when-issued basis or purchases or sales on a delayed delivery
basis. In some cases, a forward commitment may be conditioned upon the
occurrence of a subsequent event, such as approval and consummation of a
merger, corporate reorganization or debt restructuring or approval of a
proposed financing by appropriate authorities (i.e., a "when, as and if issued"
trade).

The Portfolio may invest in TBA-mortgage-backed securities. A TBA or "To Be
Announced" trade represents a contract for the purchase or sale of
mortgage-backed securities to be delivered at a future agreed-upon date;
however, the specific mortgage pool numbers or the number of pools that will be
delivered to fulfill the trade obligation or terms of the contract are unknown
at the time of the trade. Mortgage pools (including fixed rate or variable rate
mortgages) guaranteed by the Government National Mortgage Association, or GNMA,
the Federal National Mortgage Association, or FNMA, or the Federal Home Loan
Mortgage Corporation, or FHLMC, are subsequently allocated to the TBA
transactions.

When forward commitments with respect to fixed-income securities are
negotiated, the price, which is generally expressed in yield terms, is fixed at
the time the commitment is made, but payment for and delivery of the securities
take place at a later date. Securities purchased or sold under a forward
commitment are subject to market fluctuation and no interest or dividends
accrue to the purchaser prior to the settlement date. There is the risk of loss
if the value of either a purchased security declines before the settlement date
or the security sold increases before the settlement date. The use of forward
commitments helps the Portfolio to protect against anticipated changes in
interest rates and prices.

ILLIQUID SECURITIES
Under current Commission guidelines, the Portfolio limits its investments in
illiquid securities to 15% of its net assets. The term "illiquid securities"
for this purpose means securities that cannot be disposed of within seven days
in the ordinary course of business at approximately the amount the Portfolio
has valued the securities. The Portfolio invests in illiquid securities and it
may not be able to sell such securities and may not be able to realize their
full value upon sale. Restricted securities (securities subject to legal or
contractual restrictions on resale) may be illiquid. Some restricted securities
(such as securities issued pursuant to Rule 144A under the Securities Act of
1933 (the "Securities Act") or certain commercial paper) may be treated as
liquid, although they may be less liquid than registered securities traded on
established secondary markets.

INVESTMENT IN OTHER INVESTMENT COMPANIES
The Portfolio may invest in other investment companies as permitted by the
Investment Company Act of 1940, as amended (the "1940 Act") or the rules and
regulations thereunder. If the Portfolio acquires shares in investment
companies, shareholders would bear, indirectly, the expenses of such investment
companies (which may include management and advisory fees), which are in
addition to the Portfolio's expenses. The Portfolio may also invest in exchange
traded funds subject to the restrictions and limitations of the 1940 Act.

LOANS OF PORTFOLIO SECURITIES
For the purposes of achieving income, the Portfolio may make secured loans of
portfolio securities to brokers, dealers and financial institutions, provided a
number of conditions are sat-

10



isfied, including that the loan is fully collateralized. Securities lending
involves the possible loss of rights in the collateral or delay in the recovery
of collateral if the borrower fails to return the securities loaned or becomes
insolvent. When the Portfolio lends securities, its investment performance will
continue to reflect changes in the value of the securities loaned, and the
Portfolio will also receive a fee or interest on the collateral. The Portfolio
may pay reasonable finders', administrative, and custodial fees in connection
with a loan.

MORTGAGE-BACKED SECURITIES
Mortgage-backed securities may be issued by the U.S. Government or one of its
sponsored entities or may be issued by private organizations. Interest and
principal payments (including prepayments) on the mortgages underlying
mortgage-backed securities are passed through to the holders of the securities.
As a result of the pass-through of prepayments of principal on the underlying
securities, mortgage-backed securities are often subject to more rapid
prepayment of principal than their stated maturity would indicate. Prepayments
occur when the mortgagor on a mortgage prepays the remaining principal before
the mortgage's scheduled maturity date. Because the prepayment characteristics
of the underlying mortgages vary, it is impossible to predict accurately the
realized yield or average life of a particular issue of pass-through
certificates. Prepayments are important because of their effect on the yield
and price of the mortgage-backed securities. During periods of declining
interest rates, prepayments can be expected to accelerate and a portfolio that
invests in these securities would be required to reinvest the proceeds at the
lower interest rates then available. Conversely, during periods of rising
interest rates, a reduction in prepayments may increase the effective maturity
of the securities, subjecting them to a greater risk of decline in market value
in response to rising interest rates. In addition, prepayments of mortgages
underlying securities purchased at a premium could result in capital losses.

Mortgage-backed securities include mortgage pass-through certificates and
multiple-class pass-through securities, such as REMIC pass-through
certificates, CMOs and stripped mortgage-backed securities, or SMBS, and other
types of mortgage-backed securities that may be available in the future.

Guaranteed Mortgage Pass-Through Securities. The Portfolio may invest in
guaranteed mortgage pass-through securities, which represent participation
interests in pools of residential mortgage loans and are issued by U.S.
governmental or private lenders and guaranteed by the U.S. Government or one of
its agencies or instrumentalities, including but not limited to GNMA, FNMA and
FHLMC.

Multiple-Class Pass-Through Securities and Collateralized Mortgage Obligations.
Mortgage-backed securities also include CMOs and REMIC pass-through or
participation certificates that may be issued by, among others, U.S. Government
agencies and instrumentalities as well as private lenders. CMOs and REMICs are
issued in multiple classes and the principal of and interest on the mortgage
assets may be allocated among the several classes of CMOs or REMICs in various
ways. Each class of CMOs or REMICs, often referred to as a "tranche," is issued
at a specific adjustable or fixed interest rate and must be fully retired no
later than its final distribution date. Generally, interest is paid or accrued
on all classes of CMOs or REMICs on a monthly basis. The Portfolio will not
invest in the lowest tranche of CMOs and REMICs.

Typically, CMOs are collateralized by GNMA or FHLMC certificates but also may
be collateralized by other mortgage assets such as whole loans or private
mortgage pass-through securities. Debt service on CMOs is provided from
payments of principal and interest on collateral of mortgage assets and any
reinvestment income.

A REMIC is a CMO that qualifies for special tax treatment under the Internal
Revenue Code of 1986, as amended, or the Code, and invests in certain mortgages
primarily secured by interests in real property and other permitted
investments. Investors may purchase "regular" and "residual" interest shares of
beneficial interest in REMIC trusts, although the Portfolio does not intend to
invest in residual interests.

REAL ESTATE INVESTMENT TRUSTS (REITS)
REITs are pooled investment vehicles that invest primarily in income producing
real estate or real estate related loans or interests. REITs are generally
classified as equity REITs, mortgage REITs or a combination of equity and
mortgage REITs. Equity REITs invest the majority of their assets directly in
real property and derive income primarily from the collection of rents. Equity
REITs can also realize capital gains by selling properties that have
appreciated in value. Mortgage REITs invest the majority of their assets in
real estate mortgages and derive income from the collection of interest
payments. Similar to investment companies such as the Portfolio, REITs are not
taxed on income distributed to shareholders provided they comply with several
requirements of the Code. The Portfolio will indirectly bear its proportionate
share of expenses incurred by REITs in which it invests in addition to the
expenses incurred directly by the Portfolio.

ADDITIONAL RISK CONSIDERATIONS FOR REAL ESTATE INVESTMENTS
Although the Portfolio does not invest directly in real estate, it invests
primarily in securities of real estate companies and has a policy of
concentration of its investments in the real estate industry. Therefore, an
investment in the Portfolio is subject to certain risks associated with the
direct ownership of real estate and with the real estate industry in general.
These risks include, among others: possible declines in the value of real
estate; risks related to general and local economic conditions, including
increases in the rate of inflation; possible lack of availability of mortgage
funds; overbuilding; extended vacancies of properties; increases in
competition, property taxes and operating expenses; changes in zoning laws;
costs resulting from the clean-up of, and liability to third parties for
damages resulting from, environmental problems; casualty or condemnation
losses; uninsured damages from floods, earthquakes or other natural disasters;
limitations on and variations in rents; and changes in interest rates. To the
extent that assets underlying the Portfolio's investments are concentrated
geographically, by property type or in certain other respects, the Portfolio
may be

                                                                             11



subject to certain of the foregoing risks to a greater extent. These risks may
be greater for investments in non-U.S. real estate companies.

REITs. Investing in REITs involves certain unique risks in addition to those
risks associated with investing in the real estate industry in general. Equity
REITs may be affected by changes in the value of the underlying property owned
by the REITs, while mortgage REITs may be affected by the quality of any credit
extended. REITs are dependent upon management skills, are not diversified, and
are subject to heavy cash flow dependency, default by borrowers and
self-liquidation.

Investing in REITs involves risks similar to those associated with investing in
small capitalization companies. REITs may have limited financial resources, may
trade less frequently and in a limited volume and may be subject to more abrupt
or erratic price movements than larger company securities. Historically, small
capitalization stocks, such as REITs, have had more price volatility than
larger capitalization stocks.

REPURCHASE AGREEMENTS AND BUY/SELL BACK TRANSACTIONS
The Portfolio may enter into repurchase agreements in which the Portfolio
purchases a security from a bank or broker-dealer, which agrees to repurchase
the security from the Portfolio at an agreed-upon future date, normally a day
or a few days later. The purchase and repurchase obligations are transacted
under one agreement. The resale price is greater than the purchase price,
reflecting an agreed-upon interest rate for the period the buyer's money is
invested in the security. Such agreements permit the Portfolio to keep all of
its assets at work while retaining "overnight" flexibility in pursuit of
investments of a longer-term nature. If the bank or broker-dealer defaults on
its repurchase obligation, the Portfolio would suffer a loss to the extent that
the proceeds from the sale of the security were less than the repurchase price.

The Portfolio may enter into buy/sell back transactions, which are similar to
repurchase agreements. In this type of transaction, the Portfolio enters a
trade to buy securities at one price and simultaneously enters a trade to sell
the same securities at another price on a specified date. Similar to a
repurchase agreement, the repurchase price is higher than the sale price and
reflects current interest rates. Unlike a repurchase agreement, however, the
buy/sell back transaction is considered two separate transactions.

RIGHTS AND WARRANTS
Rights and warrants are option securities permitting their holders to subscribe
for other securities. Rights are similar to warrants except that they have a
substantially shorter duration. Rights and warrants do not carry with them
dividend or voting rights with respect to the underlying securities, or any
rights in the assets of the issuer. As a result, an investment in rights and
warrants may be considered more speculative than certain other types of
investments. In addition, the value of a right or a warrant does not
necessarily change with the value of the underlying securities, and a right or
a warrant ceases to have value if it is not exercised prior to its expiration
date.

SHORT SALES
The Portfolio may make short sales as a part of overall portfolio management or
to offset a potential decline in the value of a security. A short sale involves
the sale of a security that the Portfolio does not own, or if the Portfolio
owns the security, is not to be delivered upon consummation of the sale. When
the Portfolio makes a short sale of a security that it does not own, it must
borrow from a broker-dealer the security sold short and deliver the security to
the broker-dealer upon conclusion of the short sale.

If the price of the security sold short increases between the time of the short
sale and the time the Portfolio replaces the borrowed security, the Portfolio
will incur a loss; conversely, if the price declines, the Portfolio will
realize a short-term capital gain. Although the Portfolio's gain is limited to
the price at which it sold the security short, its potential loss is
theoretically unlimited.

STANDBY COMMITMENT AGREEMENTS
Standby commitment agreements are similar to put options that commit the
Portfolio, for a stated period of time, to purchase a stated amount of a
security that may be issued and sold to the Portfolio at the option of the
issuer. The price and coupon of the security are fixed at the time of the
commitment. At the time of entering into the agreement, the Portfolio is paid a
commitment fee regardless of whether the security ultimately is issued. The
Portfolio will enter into such agreements only for the purpose of investing in
the security underlying the commitment at a yield and price considered
advantageous to the Portfolio and unavailable on a firm commitment basis.

There is no guarantee that a security subject to a standby commitment will be
issued. In addition, the value of the security, if issued, on the delivery date
may be more or less than its purchase price. Since the issuance of the security
is at the option of the issuer, the Portfolio will bear the risk of capital
loss in the event that the value of the security declines and may not benefit
from an appreciation in the value of the security during the commitment period
if the issuer decides not to issue and sell the security to the Portfolio.

FOREIGN (NON-U.S.) SECURITIES
Investing in foreign securities involves special risks and considerations not
typically associated with investing in U.S. securities. The securities markets
of many foreign countries are relatively small, with the majority of market
capitalization and trading volume concentrated in a limited number of companies
representing a small number of industries. The Portfolio's investments in
foreign securities may experience greater price volatility and significantly
lower liquidity than a portfolio invested solely in securities of U.S.
companies. These markets may be subject to greater influence by adverse events
generally affecting the market, and by large investors trading significant
blocks of securities, than is usual in the United States.

Securities registration, custody, and settlement may in some instances be
subject to delays and legal and administrative uncertainties. Foreign
investment in the securities markets of certain foreign countries is restricted
or controlled to varying

12



degrees. These restrictions or controls may at times limit or preclude
investment in certain securities and may increase the cost and expenses of the
Portfolio. In addition, the repatriation of investment income, capital or the
proceeds of sales of securities from certain countries is controlled under
regulations, including in some cases the need for certain advance government
notification or authority, and if a deterioration occurs in a country's balance
of payments, the country could impose temporary restrictions on foreign capital
remittances.

The Portfolio also could be adversely affected by delays in, or a refusal to
grant, any required governmental approval for repatriation, as well as by the
application to it of other restrictions on investment. Investing in local
markets may require the Portfolio to adopt special procedures or seek local
governmental approvals or other actions, any of which may involve additional
costs to the Portfolio. These factors may affect the liquidity of the
Portfolio's investments in any country and the Adviser will monitor the effect
of any such factor or factors on the Portfolio's investments. Transaction
costs, including brokerage commissions for transactions both on and off the
securities exchanges, in many foreign countries are generally higher than in
the U.S.

Issuers of securities in foreign jurisdictions are generally not subject to the
same degree of regulation as are U.S. issuers with respect to such matters as
insider trading rules, restrictions on market manipulation, shareholder proxy
requirements, and timely disclosure of information. The reporting, accounting,
and auditing standards of foreign countries may differ, in some cases
significantly, from U.S. standards in important respects, and less information
may be available to investors in foreign securities than to investors in U.S.
securities. Substantially less information is publicly available about certain
non-U.S. issuers than is available about most U.S. issuers.

The economies of individual foreign countries may differ favorably or
unfavorably from the U.S. economy in such respects as growth of gross domestic
product or gross national product, rate of inflation, capital reinvestment,
resource self-sufficiency, and balance of payments position. Nationalization,
expropriation or confiscatory taxation, currency blockage, political changes,
government regulation, political or social instability, revolutions, wars or
diplomatic developments could affect adversely the economy of a foreign
country. In the event of nationalization, expropriation, or other confiscation,
the Portfolio could lose its entire investment in securities in the country
involved. In addition, laws in foreign countries governing business
organizations, bankruptcy and insolvency may provide less protection to
security holders such as the Portfolio than that provided by U.S. laws.

FOREIGN (NON-U.S.) CURRENCIES
The Portfolio invests some portion of its assets in securities denominated in,
and receives revenues in, foreign currencies and, will be adversely affected by
reductions in the value of those currencies relative to the U.S. Dollar.
Foreign currency exchange rates may fluctuate significantly. They are
determined by supply and demand in the foreign exchange markets, the relative
merits of investments in different countries, actual or perceived changes in
interest rates, and other complex factors. Currency exchange rates also can be
affected unpredictably by intervention (or the failure to intervene) by U.S. or
foreign governments or central banks or by currency controls or political
developments. In light of these risks, the Portfolio may engage in certain
currency hedging transactions, as described above, which involve certain
special risks. The Portfolio may also invest directly in foreign currencies for
non-hedging purposes directly on a spot basis (i.e., cash) or through
derivative transactions, such as forward currency exchange contracts, futures
and options thereon, swaps and options as described above. These investments
will be subject to the same risks. In addition, currency exchange rates may
fluctuate significantly over short periods of time, causing the Portfolio's net
asset value, or NAV, to fluctuate.

FIXED-INCOME SECURITIES
The value of the Portfolio's investments in fixed-income securities will change
as the general level of interest rates fluctuates. During periods of falling
interest rates, the values of these securities will generally rise. Conversely,
during periods of rising interest rates, the values of these securities will
generally decline. Changes in interest rates have a greater effect on
fixed-income securities with longer maturities and durations than those with
shorter maturities and durations.

FUTURE DEVELOPMENTS
The Portfolio may take advantage of other investment practices that are not
currently contemplated for use by the Portfolio, or are not available but may
yet be developed, to the extent such investment practices are consistent with
the Portfolio's investment objective and legally permissible for the Portfolio.
Such investment practices, if they arise, may involve risks that are different
from or exceed those involved in the practices described above.

CHANGES IN INVESTMENT OBJECTIVES AND POLICIES
The ALLIANCEBERNSTEIN(R) VARIABLE PRODUCTS SERIES (VPS) FUND'S (the "Fund")
Board of Directors (the "Board") may change the Portfolio's investment
objective without shareholder approval. The Portfolio will provide shareholders
with 60 days' prior written notice of any change to the Portfolio's investment
objective. Unless otherwise noted, all other investment policies of the
Portfolio may be changed without shareholder approval.

TEMPORARY DEFENSIVE POSITION
For temporary defensive purposes to attempt to respond to adverse market,
economic, political or other conditions, the Portfolio may invest in certain
types of short-term, liquid, investment grade or high quality debt securities.
While the Portfolio is investing for temporary defensive purposes, it may not
meet its investment objectives.

PORTFOLIO HOLDINGS
The Portfolio's SAI includes a description of the policies and procedures that
apply to disclosure of the Portfolio's portfolio holdings.

                                                                             13



INVESTING IN THE PORTFOLIO
--------------------------------------------------------------------------------

HOW TO BUY AND SELL SHARES
The Portfolio offers its shares through the separate accounts of life insurance
companies (the "Insurers"). You may only purchase and sell shares through these
separate accounts. See the prospectus of the separate account of the
participating insurance company for information on the purchase and sale of the
Portfolio's shares. AllianceBernstein Investments, Inc. ("ABI") may from time
to time receive payments from Insurers in connection with the sale of the
Portfolio's shares through the Insurer's separate accounts.

The purchase or sale of the Portfolio's shares is priced at the next determined
NAV after the order is received in proper form.

The Insurers maintain omnibus account arrangements with the Fund in respect of
the Portfolio and place aggregate purchase, redemption and exchange orders for
shares of the Portfolio corresponding to orders placed by the Insurer's
customers ("Contractholders") who have purchased contracts from the Insurers,
in each case, in accordance with the terms and conditions of the relevant
contract. Omnibus account arrangements maintained by the Insurers are discussed
below under "Limitations on Ability to Detect and Curtail Excessive Trading
Practices."

ABI may refuse any order to purchase shares. The Portfolio reserves the right
to suspend the sale of its shares to the public in response to conditions in
the securities markets or for other reasons.

PAYMENTS TO FINANCIAL INTERMEDIARIES
Financial intermediaries, such as the Insurers, market and sell shares of the
Portfolio and typically receive compensation for selling shares of the
Portfolio. This compensation is paid from various sources.

  Insurers or your financial intermediary receive compensation from ABI and/or
  the Adviser in several ways from various sources, which include some or all
  of the following:

  - defrayal of costs for educational seminars and training;

  - additional distribution support; and

  - payments related to providing Contractholder recordkeeping and/or
    administrative services.

ABI and/or the Adviser may pay Insurers or other financial intermediaries to
perform record-keeping and administrative services in connection with the
Portfolio. Such payments will generally not exceed 0.35% of the average daily
net assets of the Portfolio attributable to the Insurer.

OTHER PAYMENTS FOR EDUCATIONAL SUPPORT AND DISTRIBUTION ASSISTANCE
In addition to the fees described above, ABI, at its expense, currently
provides additional payments to the Insurers that sell shares of the Portfolio.
These sums include payments to reimburse directly or indirectly the costs
incurred by the Insurers and their employees in connection with educational
seminars and training efforts about the Portfolio for the Insurers' employees
and/or their clients and potential clients. The costs and expenses associated
with these efforts may include travel, lodging, entertainment and meals.

For 2010, ABI's additional payments to these firms for educational support and
distribution assistance related to the Portfolios are expected to be
approximately $400,000. In 2009, ABI paid additional payments of approximately
$400,000 for the Portfolios.

  IF ONE MUTUAL FUND SPONSOR THAT OFFERS SHARES TO SEPARATE ACCOUNTS OF AN
  INSURER MAKES GREATER DISTRIBUTION ASSISTANCE PAYMENTS THAN ANOTHER, THE
  INSURER MAY HAVE AN INCENTIVE TO RECOMMEND OR OFFER THE SHARES OF FUNDS OF
  ONE FUND SPONSOR OVER ANOTHER.

  PLEASE SPEAK WITH YOUR FINANCIAL INTERMEDIARY TO LEARN MORE ABOUT THE TOTAL
  AMOUNTS PAID TO YOUR FINANCIAL INTERMEDIARY BY THE ADVISER, ABI AND BY OTHER
  MUTUAL FUND SPONSORS THAT OFFER SHARES TO INSURERS THAT MAY BE RECOMMENDED TO
  YOU. YOU SHOULD ALSO CONSULT DISCLOSURES MADE BY YOUR FINANCIAL INTERMEDIARY
  AT THE TIME OF PURCHASE.

As of the date of this Prospectus, ABI anticipates that the Insurers or their
affiliates that will receive additional payments for educational support
include:

  AXA Advisors
  AIG SunAmerica
  Genworth Financial
  Lincoln Financial Distributors
  Merrill Lynch
  Pacific Life Insurance Co.
  Prudential
  RiverSource Distributors
  SunLife Financial
  Transamerica Capital

Although the Portfolio may use brokers and dealers who sell shares of the
Portfolio to effect portfolio transactions, the Portfolio does not consider the
sale of AllianceBernstein Mutual Fund shares as a factor when selecting brokers
or dealers to effect portfolio transactions.

FREQUENT PURCHASES AND REDEMPTIONS OF PORTFOLIO SHARES
The Fund's Board of Directors (the "Board") has adopted policies and procedures
designed to detect and deter frequent purchases and redemptions of Portfolio
shares or excessive or short-term trading that may disadvantage long-term
Contractholders. These policies are described below. There is no guarantee that

14



the Portfolio will be able to detect excessive or short-term trading and to
identify Contractholders engaged in such practices, particularly with respect
to transactions in omnibus accounts. Contractholders should be aware that
application of these policies may have adverse consequences, as described
below, and avoid frequent trading in Portfolio shares through purchases, sales
and exchanges of shares. The Portfolio reserves the right to restrict, reject,
or cancel, without any prior notice, any purchase or exchange order for any
reason, including any purchase or exchange order accepted by any Insurer or a
Contractholder's financial intermediary.

RISKS ASSOCIATED WITH EXCESSIVE OR SHORT-TERM TRADING GENERALLY. While the Fund
will try to prevent market timing by utilizing the procedures described below,
these procedures may not be successful in identifying or stopping excessive or
short-term trading in all circumstances. By realizing profits through
short-term trading, Contractholders that engage in rapid purchases and sales or
exchanges of the Portfolio's shares dilute the value of shares held by
long-term Contractholders. Volatility resulting from excessive purchases and
sales or exchanges of shares of the Portfolio, especially involving large
dollar amounts, may disrupt efficient portfolio management. In particular, the
Portfolio may have difficulty implementing its long-term investment strategies
if it is forced to maintain a higher level of its assets in cash to accommodate
significant short-term trading activity. Excessive purchases and sales or
exchanges of shares of the Portfolio may force the Portfolio to sell portfolio
securities at inopportune times to raise cash to accommodate short-term trading
activity. In addition, the Portfolio may incur increased expenses if one or
more Contractholders engage in excessive or short-term trading. For example,
the Portfolio may be forced to liquidate investments as a result of short-term
trading and incur increased brokerage costs without attaining any investment
advantage. Similarly, the Portfolio may bear increased administrative costs due
to asset level and investment volatility that accompanies patterns of
short-term trading activity. All of these factors may adversely affect the
Portfolio's performance.

Investments in foreign securities may be particularly susceptible to short-term
trading strategies. This is because foreign securities are typically traded on
markets that close well before the time the Portfolio calculates its NAV at
4:00 p.m., Eastern Time, which gives rise to the possibility that developments
may have occurred in the interim that would affect the value of these
securities. The time zone differences among international stock markets can
allow a Contractholder engaging in a short-term trading strategy to exploit
differences in share prices that are based on closing prices of foreign
securities established some time before the Portfolio calculates its own share
price (referred to as "time zone arbitrage"). The Portfolio has procedures,
referred to as fair value pricing, designed to adjust closing market prices of
foreign securities to reflect what is believed to be fair value of those
securities at the time the Portfolio calculates its NAV. While there is no
assurance, the Portfolio expects that the use of fair value pricing, in
addition to the short-term trading policies discussed below, will significantly
reduce a Contractholder's ability to engage in time zone arbitrage to the
detriment of other Contractholders.

Contractholders engaging in a short-term trading strategy may also target a
Portfolio that does not invest primarily in foreign securities. If the
Portfolio invests in securities that are, among other things, thinly traded,
traded infrequently, or relatively illiquid, it has the risk that the current
market price for the securities may not accurately reflect current market
values. Contractholders may seek to engage in short-term trading to take
advantage of these pricing differences (referred to as "price arbitrage"). The
Portfolio may be adversely affected by price arbitrage.

POLICY REGARDING SHORT-TERM TRADING. Purchases and exchanges of shares of the
Portfolio should be made for investment purposes only. The Fund seeks to
prevent patterns of excessive purchases and sales or exchanges of shares of the
Portfolio. The Fund will seek to prevent such practices to the extent they are
detected by the procedures described below. Insurers utilizing omnibus account
arrangements may not identify to the Fund, ABI or ABIS Contractholders'
transaction activity relating to shares of the Portfolio on an individual
basis. Consequently, the Fund, ABI and ABIS may not be able to detect excessive
or short-term trading in shares of the Portfolio attributable to a particular
Contractholder who effects purchase and redemption and/or exchange activity in
shares of the Portfolio through an Insurer acting in an omnibus capacity. In
seeking to prevent excessive or short-term trading in shares of the Portfolio,
including the maintenance of any transaction surveillance or account blocking
procedures, the Fund, ABI and ABIS consider the information actually available
to them at the time. The Fund reserves the right to modify this policy,
including any surveillance or account blocking procedures established from time
to time to effectuate this policy, at any time without notice.

.  TRANSACTION SURVEILLANCE PROCEDURES. The Fund, through its agents, ABI and
   AllianceBernstein Investor Services, Inc. ("ABIS"), maintains surveillance
   procedures to detect excessive or short-term trading in Portfolio shares.
   This surveillance process involves several factors, which include
   scrutinizing individual Insurer's omnibus transaction activity in Portfolio
   shares in order to seek to ascertain whether any such activity attributable
   to one or more Contractholders might constitute excessive or short-term
   trading. Insurer's omnibus transaction activity identified by these
   surveillance procedures, or as a result of any other information actually
   available at the time, will be evaluated to determine whether such activity
   might indicate excessive or short-term trading activity attributable to one
   or more Contractholders. These surveillance procedures may be modified from
   time to time, as necessary or appropriate to improve the detection of
   excessive or short-term trading or to address specific circumstances.

.  ACCOUNT BLOCKING PROCEDURES. If the Fund determines, in its sole discretion,
   that a particular transaction or pattern of transactions identified by the
   transaction surveillance procedures described above is excessive or
   short-term trading in nature, the relevant Insurer's omnibus account(s) will
   be

                                                                             15



   immediately "blocked" and no future purchase or exchange activity will be
   permitted, except to the extent the Fund, ABI or ABIS has been informed in
   writing that the terms and conditions of a particular contract may limit the
   Fund's ability to apply its short-term trading policy to Contractholder
   activity as discussed below. As a result, any Contractholder seeking to
   engage through an Insurer in purchase or exchange activity in shares of the
   Portfolio under a particular contract will be prevented from doing so.
   However, sales of Portfolio shares back to the Portfolio or redemptions will
   continue to be permitted in accordance with the terms of the Portfolio's
   current Prospectus. In the event an account is blocked, certain
   account-related privileges, such as the ability to place purchase, sale and
   exchange orders over the internet or by phone, may also be suspended. As a
   result, unless the Contractholder redeems his or her shares, the
   Contractholder effectively may be "locked" into an investment in shares of
   one or more of the Portfolio that the Contractholder did not intend to hold
   on a long-term basis or that may not be appropriate for the Contractholder's
   risk profile. To rectify this situation, a Contractholder with a "blocked"
   account may be forced to redeem Portfolio shares, which could be costly if,
   for example, these shares have declined in value. To avoid this risk, a
   Contractholder should carefully monitor the purchases, sales, and exchanges
   of Portfolio shares and avoid frequent trading in Portfolio shares. An
   Insurer's omnibus account that is blocked will generally remain blocked
   unless and until the Insurer provides evidence or assurance acceptable to
   the Fund that one or more Contractholders did not or will not in the future
   engage in excessive or short-term trading.

.  APPLICATIONS OF SURVEILLANCE PROCEDURES AND RESTRICTIONS TO OMNIBUS
   ACCOUNTS. The Portfolio applies its surveillance procedures to Insurers. As
   required by Securities and Exchange Commission ("Commission") rules, the
   Portfolio has entered into agreements with all of its financial
   intermediaries that require the financial intermediaries to provide the
   Portfolio, upon the request of the Portfolio or its agents, with individual
   account level information about their transactions. If the Portfolio detects
   excessive trading through its monitoring of omnibus accounts, including
   trading at the individual account level, Insurers will also execute
   instructions from the Portfolio to take actions to curtail the activity,
   which may include applying blocks to account to prohibit future purchases
   and exchanges of Portfolio shares.

HOW THE PORTFOLIO VALUES ITS SHARES
The Portfolio's NAV is calculated at the close of regular trading on the
Exchange (ordinarily, 4:00 p.m., Eastern Time), only on days when the Exchange
is open for business. To calculate NAV, the Portfolio's assets are valued and
totaled, liabilities are subtracted, and the balance, called net assets, is
divided by the number of shares outstanding. If the Portfolio invests in
securities that are primarily traded on foreign exchanges that trade on
weekends or other days when the Portfolio does not price its shares, the NAV of
the Portfolio's shares may change on days when shareholders will not be able to
purchase or redeem their shares in the Portfolio.

The Portfolio values its securities at their current market value determined on
the basis of market quotations or, if market quotations are not readily
available or are unreliable, at "fair value" as determined in accordance with
procedures established by and under the general supervision of the Board. When
the Portfolio uses fair value pricing, it may take into account any factors it
deems appropriate. The Portfolio may determine fair value based upon
developments related to a specific security, current valuations of foreign
stock indices (as reflected in U.S. futures markets) and/or U.S. sector or
broader stock market indices. The prices of securities used by the Portfolio to
calculate its NAV may differ from quoted or published prices for the same
securities. Fair value pricing involves subjective judgments and it is possible
that the fair value determined for a security is materially different than the
value that could be realized upon the sale of that security.

The Portfolio expects to use fair value pricing for securities primarily traded
on U.S. exchanges only under very limited circumstances, such as the early
closing of the exchange on which a security is traded or suspension of trading
in the security. The Portfolio may use fair value pricing more frequently for
securities primarily traded in foreign markets because, among other things,
most foreign markets close well before the Portfolio values its securities at
4:00 p.m., Eastern Time. The earlier close of these foreign markets gives rise
to the possibility that significant events, including broad market moves, may
have occurred in the interim. For example, the Portfolio believes that foreign
security values may be affected by events that occur after the close of foreign
securities markets. To account for this, the Portfolio may frequently value
many of its foreign equity securities using fair value prices based on third
party vendor modeling tools to the extent available.

Subject to the Board's oversight, the Board has delegated responsibility for
valuing the Portfolio's assets to the Adviser. The Adviser has established a
Valuation Committee, which operates under the policies and procedures approved
by the Board, to value the Portfolio's assets on behalf of the Portfolio. The
Valuation Committee values Portfolio assets as described above.

Your order for purchase, sale, or exchange of shares is priced at the
next-determined NAV after your order is received in proper form by the
Portfolio.

MANAGEMENT OF THE PORTFOLIO
--------------------------------------------------------------------------------

INVESTMENT ADVISER
The Portfolio's adviser is AllianceBernstein L.P., 1345 Avenue of the Americas,
New York, New York 10105. The Adviser is a leading international investment
adviser managing client accounts with assets as of December 31, 2009, totaling
more than $496 billion (of which over $76 billion represented assets of
investment companies). As of December 31, 2009, the Adviser managed retirement
assets for many of the largest public and private employee benefit plans
(including 42 of the nation's FORTUNE 100 companies), for public employee
retirement funds in 39 states, for investment companies, and for foundations,
endowments, banks and insurance companies worldwide. Currently, there are 35
registered investment companies managed by the Adviser, comprising 110 separate
investment portfolios, with approximately 3.5 million retail accounts.

The Adviser provides investment advisory services and order placement
facilities for the Portfolio. For these advisory services, for the fiscal year
ended December 31, 2009, the Portfolio paid the Adviser as a percentage of
average daily net assets .55%.

A discussion regarding the basis for the Board's approval of the Portfolio's
investment advisory agreement is available in the Portfolio's semi-annual
report to shareholders for the period ending June 20, 2009.

The Adviser may act as an investment adviser to other persons, firms, or
corporations, including investment companies, hedge funds, pension funds, and
other institutional investors. The Adviser may receive management fees,
including performance fees, that may be higher or lower than the advisory fees
it receives from the Portfolio. Certain other clients of the Adviser may have
investment objectives and policies similar to those of the Portfolio. The
Adviser may, from time to time, make recommendations that result in the
purchase or sale of a particular security by its other clients simultaneously
with the Portfolio. If transactions on behalf of more than one client during
the same period increase the demand for securities being purchased or the
supply of securities being sold, there may be an adverse effect on price or
quantity. It is the policy of the Adviser to allocate advisory recommendations
and the placing of orders in a manner that is deemed equitable by the Adviser
to the accounts involved, including the Portfolio. When two or more of the
clients of the Adviser (including the Portfolio) are purchasing or selling the
same security on a given day from the same broker-dealer, such transactions may
be averaged as to price.

PORTFOLIO MANAGERS
The management of, and investment decisions for, the Portfolio is made by the
Adviser's REIT Senior Investment Management Team. The REIT Senior Investment
Management Team relies heavily on the fundamental analysis and research of the
Adviser's large internal research staff. No one person is principally
responsible for making recommendations for the Portfolio's portfolio.

The following table lists the persons within the REIT Senior Investment
Management Team with the most significant responsibility for the day-to-day
management of the Portfolio's portfolio, the year that each person assumed
joint and primary responsibility for the Portfolio, and each person's principal
occupation during the past five years:

LEGAL PROCEEDINGS
On October 2, 2003, a purported class action complaint entitled Hindo et al. v.
AllianceBernstein Growth & Income Fund et al. (the "Hindo Complaint") was filed
against the Adviser; AllianceBernstein Holding L.P. ("Holding");
AllianceBernstein Corporation; AXA Financial, Inc.; the AllianceBernstein
Mutual Funds, certain officers of the Adviser ("AllianceBernstein defendants");
and certain other unaffiliated defendants, as well as unnamed Doe defendants.
The Hindo Complaint was filed in the United States District Court for the
Southern District of New York by alleged shareholders of two of the
AllianceBernstein Mutual Funds. The Hindo Complaint alleges that certain of the
Alliance defendants failed to disclose that they improperly allowed certain
hedge funds and other unidentified parties to engage in "late trading" and
"market timing" of AllianceBernstein Mutual Fund securities, violating Sections
11 and 15 of the Securities Act of 1933, Sections 10(b) and 20(a) of the
Securities and Exchange Act of 1934, and Sections 206 and 215 of the Investment
Advisers Act of 1940. Plaintiffs seek an unspecified amount of compensatory
damages and rescission of

                                                                             17



their contracts with the Adviser, including recovery of all fees paid to the
Adviser pursuant to such contracts.

Following October 2, 2003, additional lawsuits making factual allegations
generally similar to those in the Hindo Complaint were filed in various federal
and state courts against the Adviser and certain other defendants. On
September 29, 2004, plaintiffs filed consolidated amended complaints with
respect to four claim types: mutual fund shareholder claims; mutual fund
derivative claims; derivative claims brought on behalf of Holding; and claims
brought under ERISA by participants in the Profit Sharing Plan for Employees of
the Adviser. All four complaints include substantially identical factual
allegations, which appear to be based in large part on the Order of the
Commission dated December 18, 2003 as amended and restated January 15, 2004 and
the New York State Attorney General Assurance of Discontinuance dated
September 1, 2004.

On April 21, 2006, the Adviser and attorneys for the plaintiffs in the mutual
fund shareholder claims, mutual fund derivative claims, and ERISA claims
entered into a confidential memorandum of understanding containing their
agreement to settle these claims. The agreement will be documented by a
stipulation of settlement and will be submitted for court approval at a later
date. The settlement amount ($30 million), which the Adviser previously accrued
and disclosed, has been disbursed. The derivative claims brought on behalf of
Holding, in which plaintiffs seek an unspecified amount of damages, remain
pending.

It is possible that these matters and or other developments resulting from
these matters could result in increased redemptions of the affected fund's
shares or other adverse consequences to those funds. This may require those
funds to sell investments to provide for sufficient liquidity and could also
have an adverse effect on the investment performance of the Portfolio. However,
the Adviser believes that these matters are not likely to have a material
adverse effect on its ability to perform advisory services relating to those
funds or the Portfolio.

FINANCIAL HIGHLIGHTS
--------------------------------------------------------------------------------

The financial highlights table is intended to help you understand the
Portfolio's financial performance for the past 5 years. Certain information
reflects financial results for a single share of a class of the Portfolio. The
total returns in the table represent the rate that an investor would have
earned (or lost) on an investment in the Portfolio (assuming reinvestment of
all dividends and distributions). The total returns in the table do not take
into account separate account charges. If separate account charges were
included, an investor's returns would have been lower. This information has
been audited by Ernst & Young LLP, the independent registered public accounting
firm for the Portfolio, whose report, along with the Portfolio's financial
statements, are included in the Portfolio's annual report, which is available
upon request.

APPENDIX A
--------------------------------------------------------------------------------

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION
The settlement agreement between the Adviser and the New York Attorney General
requires the Fund to include the following supplemental hypothetical investment
information that provides additional information calculated and presented in a
manner different from expense information found under "Fees and Expenses of the
Portfolio" in this Prospectus about the effect of the Portfolio's expenses,
including investment advisory fees and other Portfolio costs, on the
Portfolio's returns over a 10-year period. The chart shows the estimated
expenses that would be charged on a hypothetical investment of $10,000 in
Class A shares of the Portfolio assuming a 5% return each year. Except as
otherwise indicated, the chart also assumes that the current annual expense
ratio stays the same throughout the 10-year period. The current annual expense
ratio for the Portfolio is the same as stated under "Fees and Expenses of the
Portfolio." There are additional fees and expenses associated with variable
products. These fees can include mortality and expense risk charges,
administrative charges, and other charges that can significantly affect
expenses. These fees and expenses are not reflected in the following expense
information. Your actual expenses may be higher or lower.
