At meetings held on February 67, 2018, the Board of Directors
approved the following changes to the Portfolios
principal strategies, which do not require stockholder approval and
will take effect on or about May 1, 2018.

The Principal Strategies section will be replaced with the following:

The Portfolio invests in a portfolio of equity and fixedincome securities
that is designed as a solution for investors
who seek a moderate tilt toward equity returns but also want the risk
diversification offered by fixedincome securities and the broad
diversification of their equity risk across styles, capitalization ranges
and geographic regions. Under normal circumstances, the Portfolio will
invest at least 25% of its total assets in equity securities and at least
25% of its total assets in fixedincome securities with a goal of
providing moderate upside potential without excessive volatility. The
Portfolio also seeks exposure to real assets by investing in real
estaterelated equity  securities including real estate investment trusts, or
REITs, natural resource equity securities and inflationsensitive equity
securities. The Portfolio pursues a global strategy, typically investing in
securities of issuers located in the United States and in other countries
throughout the world, including emerging market countries.

The Adviser expects that the Portfolio will normally invest a greater
percentage of its total assets in equity securities
than in fixedincome securities, and will generally invest in equity
securities both directly and through underlying
investment companies advised by the Adviser Underlying Portfolios. A
significant portion of the Portfolios assets are expected to be invested
directly in U.S. largecap equity securities, primarily common stocks, in
accordance with the Advisers U.S. Strategic Equities investment
strategy U.S. Strategic Equities. Under U.S. Strategic Equities,
portfolio managers of the Adviser that specialize in various investment
disciplines identify highconviction largecap equity securities based on
their fundamental investment research for potential investment by the
Portfolio. These securities are then assessed in terms of both this
fundamental research and quantitative analysis in creating the equity
portion of the Portfolios portfolio. In applying the quantitative analysis,
the Adviser considers a number of metrics that historically have
provided some indication of favorable future returns, including metrics
related to valuation, quality, investor behavior and corporate behavior.

In addition, the Portfolio seeks to achieve exposure to international
largecap equity securities through investments in the International
Strategic Equities Portfolio of Bernstein Fund, Inc. Bernstein
International Strategic Equities Portfolio and the International
Portfolio of Sanford C. Bernstein Fund, Inc. SCB International
Portfolio, each a registered investment company advised by the
Adviser. The Portfolio also invests in other Underlying Portfolios to
efficiently gain exposure to certain other types of equity securities,
including small and midcap and emerging market equity securities. The
Adviser selects an Underlying Portfolio based on the segment of the
equity market to which the Underlying Portfolio provides exposure, its
investment philosophy, and how it complements and diversifies the
Portfolios overall portfolio.

Bernstein International Strategic Equities Portfolio and SCB
International Portfolio focus on investing in nonU.S.
largecap and midcap equity securities. Bernstein International Strategic
Equities Portfolio follows a strategy similar to U.S. Strategic Equities,
but in the international context. In managing SCB International
Portfolio, the Adviser selects stocks by drawing on the capabilities of
its separate investment teams specializing in different investment
disciplines, including value, growth, stability and others.

In selecting fixedincome investments, the Adviser may draw on the
capabilities of separate investment teams that
specialize in different areas that are generally defined by the maturity
of the debt securities and/or their ratings, and
which may include subspecialties such as inflationindexed securities.
These fixedincome teams draw on the
resources and expertise of the Advisers internal fixedincome research
staff, which includes over 50 dedicated fixed income research analysts
and economists. The Portfolios fixedincome securities will primarily be
investment grade
debt securities, but are expected to include lowerrated securities junk
bonds and preferred stock.

The Portfolio expects to enter into derivative transactions, such as
options, futures contracts, forwards and swaps.
Derivatives may provide a more efficient and economical exposure to
market segments than direct investments, and
may also be a more efficient way to alter the Portfolios exposure. The
Portfolio may, for example, use credit default, interest rate and total
return swaps to establish exposure to the fixedincome markets or
particular fixedincome securities and, as noted below, may use
currency derivatives to hedge foreign currency exposure.

Fluctuations in currency exchange rates can have a dramatic impact on
the returns of foreign securities. The Adviser
may employ currency hedging strategies in the Portfolio or the
Underlying Portfolios, including the use of currencyrelated derivatives,
to seek to reduce currency risk in the Portfolio or the Underlying
Portfolios, but it is not required to do so. The Adviser will generally
employ currency hedging strategies more frequently in the fixedincome
portion of the Portfolio than in the equity portion.

The following risk factor will be added in the section Principal Risks:

 Investment in Other Investment Companies Risk: As with other
investments, investments in other
investment companies are subject to market and selection risk. In
addition, Contractholders invested in the
Portfolio bear both their proportionate share of expenses in the
Portfolio including management fees and,
indirectly, the expenses of the investment companies to the extent these
expenses are not waived or
reimbursed by the Adviser.

The following risk factor will replace Real Estate Risk in the section
Principal Risks
:
 Real Assets Risk: The Portfolios investments in securities linked to
real assets involve significant risks,
including financial, operating, and competitive risks. Investments in
securities linked to real assets expose the
Portfolio to adverse macroeconomic conditions, such as a rise in
interest rates or a downturn in the economy
in which the asset is located. The Portfolios investments in real estate
securities have many of the same risks
as direct ownership of real estate, including the risk that the value of
real estate could decline due to a variety
of factors that affect the real estate market generally. Investments in
REITs may have additional risks. REITs
are dependent on the capability of their managers, may have limited
diversification, and could be
significantly affected by changes in tax laws.
