         Re:   AllianceBernstein Corporate Shares - AllianceBernstein
               Tax-Aware Real Return Income Shares
               Post-Effective Amendment No. 9
               File Nos. 333-112207 and 811-21497

Dear Ms. Stirling:

      This letter responds to comments of the staff (the "Staff") of the
Securities and Exchange Commission (the "SEC") to the post-effective amendments
to the registration statement filed on Form N-1A of AllianceBernstein Corporate
Shares on behalf of its series, AllianceBernstein Tax-Aware Real Return Income
Shares (the "Fund"), as provided orally to Young Seo of this office on March 24,
2011. The Staff's comments and our responses are discussed below.

Prospectus
----------

Comment 1   Fees and Expenses of the Fund: Please confirm that the Fund pays no
            acquired fund fees and expenses.

Response:   The Fund has not commenced operations.

Comment 2   Principal Strategies: The first sentence of the second paragraph
            states that "[t]he Fund pursues its objective by investing
            principally in municipal securities that pay interest exempt from
            federal taxation." A disclosure similar to the one in the Statement
            of Additional Information should be included in the Principal
            Strategies section of the Prospectus also. The first sentence in the
            "Alternative Minimum Tax" section under "Information About the Fund
            and Its Investments" of the SAI states that "[a]s a matter of
            fundamental policy, the Fund invests, under normal circumstances, at
            least 80% of its net assets in municipal securities that pay
            interest that is exempt from federal income tax."

Response:   The disclosure in the SAI has been deleted. The Fund does not have a
            policy to invest 80% of its assets in municipal securities.

Comment 3   Principal Strategies: The first sentence of the fifth paragraph
            states that the Fund may make significant use of derivatives. As
            reflected in the Staff letter to ICI regarding derivatives (the "ICI
            Letter"), disclosure of the Fund's use of derivatives should include
            the extent of the Fund's use of derivatives. Furthermore, as
            explained in the ICI Letter, the disclosure should provide an
            explanation of the purpose of the use of derivatives. The second
            sentence of the fifth paragraph states that "[t]o provide inflation
            protection, the Fund will enter into various kinds of inflation swap
            agreements." If there are any other purposes for which derivatives
            are used, other than the one currently disclosed, those purposes
            should also be disclosed.

Response:   We believe the disclosure appropriately describes the Fund's use of
            derivatives and have not revised the disclosure in response to this
            comment.

Comment 4   Principal Strategies: In the sixth paragraph, the last bullet point
            ("derivatives, such as options, futures, forwards and swaps") may be
            deleted since the Fund's use of derivatives has already been
            discussed in the preceding paragraph.

Response:   We have revised the disclosure in response to this comment.

Comment 5   Principal Strategies: The first sentence of the last paragraph
            states that "[t]he Fund may make short sales of securities or
            maintain a short position". Any short sale expenses should be
            disclosed in the fee table under the heading "Other Expenses".

Response:   The Fund has not commenced operations and does not have short sale
            expenses to disclose in the Fee Table.

Comment 6   Principal Risks - Credit Risk: The last sentence states that
            "[i]nvestments 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." Please include a disclosure that
            these fixed-income securities are commonly known as "junk bonds" and
            that they are considered "speculative".

Response:   We have revised the disclosure in response to this comment to note
            that the fixed-income securities are commonly known as "junk bonds"
            but we have not described them as speculative. We believe that
            disclosing the risks of these fixed-income securities is appropriate
            and that the use of the term "speculative" does not impart any
            additional information necessary for investor understanding of these
            securities' risks.

Comment 7   Principal Risks - Derivatives Risk: Disclosure regarding derivatives
            risk should be tailored to the specific purpose for which the Fund
            intends to use derivatives for.

Response:   We have revised the disclosure in response to this comment.

Comment 8   Purchase and Sale of Fund Shares: The second sentence of the first
            paragraph states that "[s]hares of the Fund are offered exclusively
            through registered investment advisers approved by the Adviser." The
            second paragraph, however, states that "[y]ou may sell (redeem) your
            shares through your broker-dealer". Please confirm whether the
            disclosure regarding redemption should also state "registered
            investment advisers" in lieu of "broker-dealer".

Response:   We have revised the disclosure in response to this comment.

Comment 9   Additional Information About the Fund's Risks and Investments -
            Derivatives: Disclosure regarding derivatives should be tailored to
            the Fund's anticipated use of derivatives.

Response:   We believe that the disclosure appropriately describes derivatives
            in which the Fund may invest and have not revised the disclosure in
            response to this comment.

Comment 10  Additional Information About the Fund's Risks and Investments -
            Investments In Below Investment Grade Fixed-Income Securities:
            Please include a disclosure that these fixed-income securities are
            considered "speculative".

Response:   We do not believe that the addition of the word "speculative" is
            necessary for investor understanding of the risks of investments in
            below-investment grade securities as disclosed in the Prospectus and
            have not revised the disclosure in response to this comment.

Comment 11  Management of the Fund - Investment Adviser: A statement that the
            Adviser is responsible for all expenses should be included, as
            required to be included in the SAI.

Response:   Item 10(a)(iii) requires disclosure about the aggregate fee payable
            to the investment adviser. It does not require disclosure about who
            pays fund expenses or the allocation of those expenses. In addition,
            disclosure about the Adviser's responsibility for the Fund's
            expenses is included in the introduction to the Fee Table in the
            Summary Information at the beginning of the Prospectus. We have not
            revised the disclosure in response to this comment.

Comment 12  Management of the Fund - Portfolio Managers: As required under Item
            10(a)(2) of Form N-1A, a disclosure regarding the following should
            be included in the description of the portfolio managers: a brief
            description of the person's role on the team (e.g., lead member),
            including a description of any limitations on the person's role and
            the relationship between the person's role and the roles of other
            persons who have responsibility for the day-to-day management of the
            Fund's portfolio.

Response:   The disclosure lists the members of the portfolio management team
            with the most significant responsibility for day-to-day management
            of the Fund's portfolio and describes those individuals as being
            jointly and primarily responsible for the Fund's portfolio. There is
            no difference in their roles so that additional disclosure about
            limitations or relationships is not relevant. We have not revised
            the disclosure in response to this comment.

Comment 13  Appendix B - Hypothetical Investment and Expense Information: The
            third paragraph states that "[t]he chart does not reflect the fees,
            including the "wrap fee," paid by you to your sponsoring investment
            adviser" and "[t]he chart also does not reflect the sub-advisory fee
            paid by your sponsoring investment adviser to AllianceBernstein
            L.P." This disclosure does not make it clear who the "sponsoring
            investment adviser" is. Also, it is not clear which expenses are
            included in the calculation of hypothetical expenses if the
            hypothetical expenses do not include management fee.

Response:   The Hypothetical Investment and Expense Information is included as
            an Appendix to the Prospectus because it is required as a condition
            of a settlement agreement between the Adviser and the Office of the
            New York Attorney General dated September 1, 2004. It is not
            required by Form N-1A and we are surprised that the Staff is now
            commenting on it, particularly since this same disclosure has
            appeared in prospectuses, which have been reviewed by the Staff, for
            AllianceBernstein funds offered in wrap fee programs for several
            years. In any case, we believe the first paragraph of introduction
            to the investment and expense information describes who the
            sponsoring investment adviser is. We believe that it is also clear
            that the information includes a hypothetical annual expense ratio
            notwithstanding that the Adviser has agreed irrevocably to waive all
            fees and pay or reimburse all expenses, except extraordinary
            expenses. We have not revised the disclosure in response to this
            comment.

Comment 14  Appendix B - Hypothetical Investment and Expense Information: The
            last sentence of the second paragraph states that "[t]he annual
            expense ratio is hypothetical because AllianceBernstein L.P. has
            agreed irrevocably to waive all fees and pay or reimburse all
            expenses, except extraordinary expenses, incurred by the Fund." The
            use of the word, "irrevocably", appears to imply that the waiver
            will be in place for perpetuity, when one would think that the
            Adviser is agreeing to pay expenses only through the term of the
            current investment advisory contract. Please clarify what is meant
            by "irrevocably".

Response:   We reiterate our response to Comment 13 regarding the Staff's
            comments on Appendix B. "Irrevocably" in this context means that the
            Adviser has contractually agreed to waive all fees and reimburse
            expenses as long as the Investment Advisory Agreement is in effect.

Comment 15  Back Cover: The back cover page states that "[t]he Fund's SAI,
            the independent registered public accounting firm's report and
            financial statements in the Fund's most recent annual report to
            shareholders are incorporated by reference into (and are legally
            part of) this Prospectus." Under Rule 411(a) and General Instruction
            D.1.(b) of Form N-1A, the only information permitted to be
            incorporated into the Prospectus by reference are financial
            highlights information and the SAI.

Response:   We have revised the disclosure in response to this comment.

SAI

Comment 16  Information About the Fund and Its Investments: The first sentence
            under "Alternative Minimum Tax" section states that "[a]s a matter
            of fundamental policy, the Fund invests, under normal circumstances,
            at least 80% of its net assets in municipal securities that pay
            interest that is exempt from federal income tax." Since this is a
            fundamental policy, a disclosure that it may not be changed without
            a shareholder vote should be included. Please include this
            disclosure or, alternatively, move this section to the "Fundamental
            Investment Policies" section.

Response:   As noted above in response to Comment 2, this disclosure has been
            deleted.

Comment 17  Management of the Fund - The Adviser: The seventh paragraph states
            that the Adviser is responsible for certain expenses incurred by the
            Fund and the eight paragraph states that the Fund has assumed the
            obligation for payment of certain of its other expenses. Please
            provide disclosure regarding any exclusions to which expenses the
            Adviser is going to pay. For example, since the Fund may short
            securities, a disclosure should be provided regarding whether the
            Adviser is responsible for the short-sale expenses. If the Adviser
            is not responsible for those expenses, they should be included in
            the fee table.

Response:   We believe that the disclosure clearly describes expense that are
            paid by the Adviser and the expenses paid by the Fund. We have not
            revised the disclosure in response to this comment.

Part C

Comment 18  Exhibits:  Please file the amended Advisory Agreement.

Response:   We will file the amended Advisory Agreement with the 485(b) filing.

                                     * * *

      We hereby acknowledge that (i) the Fund is responsible for the adequacy
and accuracy of the disclosures in the filing; (ii) Staff comments or changes to
disclosure in response to Staff comments in the filing reviewed by the Staff do

(iii) the Fund may not assert Staff comments as a defense in any proceedings
initiated by the SEC or any person under the federal securities laws of the
United States.
