         Post-Effective Amendment No. 145
         File Nos. 2-29901 and 811-01716

Dear Ms. O'Neal Johnson:

      This letter provides an additional response to comments of the staff (the
"Staff") of the Securities and Exchange Commission (the "SEC") to the
post-effective amendment to the registration statement filed on Form N-1A that
includes the AllianceBernstein Emerging Markets Core Portfolio ("Emerging
Markets Core") and the AllianceBernstein Emerging Markets Growth Portfolio
("Emerging Markets Growth") (each a "Fund" and collectively the "Funds"), as
provided orally to Joanne A. Skerrett of this office on March 27, 2014. The
Staff's comment and our response are discussed below.

Prospectus
----------

Emerging Markets Core and Emerging Markets Growth
--------------------------------------------------

Comment 10: Principal Strategies: Please inform the Staff how much of each
            Fund's assets will be invested in emerging markets derivatives and
            how such derivatives will be valued for purposes of the 80% Test.

Response:   The Funds do not have a strategy to invest any particular amount of
            their assets in emerging market derivatives, although neither Fund
            has a principal investment strategy to invest in derivatives other
            than currency derivatives.

            With respect to the 80% Test, Rule 35d-1, as you are aware, requires
            an investment company with a name that suggests a particular
            investment, country or geographic region to invest at least 80% of
            its assets in the type of investment, country or region suggested by
            its name. In the adopting release for such Rule (Release No.
            IC-24828 (Jan. 17, 2001)), the SEC explained that it was not
            adopting proposed criteria suggesting that the 80% Test could only
            be satisfied by investment in securities of the type suggested by
            the fund's name. Instead, the SEC adopted an approach that allows
            investment companies the flexibility to invest in additional types
            of investments that expose a fund's assets to the economic fortunes
            and risks of the investments indicated by its name (in this case,
            emerging market securities). In this respect, the SEC gave an
            example that a fund with a name suggesting an emphasis in a certain
            country or geographic region may, in complying with the Rule, invest
            in a foreign stock index futures contract traded on a U.S.
            commodities exchange.

            The Funds may determine that it is more efficient and economical to
            invest in emerging market countries through a futures contract or
            other derivative instrument rather than by making direct investments
            in securities of emerging market countries. In the case of a futures
            contract, variation margin payments are made on a daily or other
            frequent basis, and the value of the futures contract on the books
            of the fund (the Fund's obligation to make or right to receive
            margin payments relating to prior price movements) will generally be
            quite small and does not approximate the exposure that the Fund has
            to the assets underlying the futures contract by virtue of the
            futures contract. Rather, we believe that in such a case the
            notional amount of the futures contract adjusted for changes in the
            value of the underlying assets provides a better measure of the
            Fund's exposure to such assets, as an investment in the futures
            contract is the economic equivalent of an investment in the
            underlying assets. For example, if a Fund were to buy a futures
            contract on an emerging market index with a notional amount of $1
            million, and the value of the index declined by 10% while the Fund
            held the futures contract, the Fund would effectively have $900,000
            of emerging markets exposure through that futures contract, even
            though the value of the futures contract on the books of the Fund
            may be at or near zero. We believe that it is appropriate and
            consistent with the SEC's economic exposure approach to use the
            current market value of the notional amount of the futures contract
            for compliance with the names test.

            Of course, we do not mean to suggest that the notional amount of a
            derivative instrument should always be used to measure exposure to
            the assets underlying the derivative instrument for purposes of an
            80% test under Rule 35d-1. For example, the purchase of an
            out-of-the-money call option on an emerging market security is not
            the economic equivalent of a purchase of the security, and the
            market price of such an option would generally better represent the
            Fund's emerging market exposure than the notional amount of the
            option (i.e., the value of the underlying security). Also,
            specifically as to currency derivatives, which as noted above are
            the only derivatives that the Funds may use as a principal
            investment strategy, hedging the Funds' emerging market currency
            exposure back to the U.S. dollar through derivatives would have no
            bearing on the Funds' exposure to emerging market securities, so the
            value of any such currency derivatives would generally not be
            included in the numerator for the Funds' 80% test.

                                                     * * *
