                 File Nos. 33-34001 and 811-06068
Dear Mr. Oh:

         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 statements filed on Form N-1A of AB Government STIF
Portfolio ("Government STIF"), a series of AB Fixed-Income Shares, Inc., and AB
Exchange Reserves ("Exchange Reserves", and together with Government STIF, the
"Funds"), as provided orally to Anna C. Weigand of this office on April 22,
2016. The Staff's comments and our responses are discussed below. As provided by
the Staff, the comments below are based on the Exchange Reserves registration
statement, unless otherwise noted, and apply also to the Government STIF
registration statement unless the comments indicate otherwise.

General
-------

Comment 1:  Please ensure that the facing sheet of the Fund's next
            post-effective amendment includes: (1) the approximate date of the
            proposed public offering and (2) the title of the securities being
            registered and appropriate related disclosure.

Response:   The facing sheet of the Fund's next post-effective amendment will
            include the approximate date of the proposed public offering and the
            title of the securities being registered and appropriate related
            disclosure.

Comment 2:  Please update the series and class identifiers on EDGAR to
            appropriately reflect the Fund's name change. In the case of
            Government STIF, please also add class identifiers for the new
            classes.

Response:   The series and class identifiers, and class identifiers for new
            classes as applicable, will be updated and added on EDGAR.

Comment 3:  With respect to Government STIF, please provide the exchange ticker
            symbols for each new class of the Fund on the cover of the
            Prospectus and Statement of Additional Information ("SAI"). Please
            also include all missing information in the Prospectus prior to the
            effective date of the filing.

Response:   The Prospectus and SAI will be revised to include ticker symbols for
            the classes that will be offered initially and applicable missing
            information. We note that Class A, Class C, Advisor Class, Class R,
            Class K, Class I, Class Z and Class 1 will be included in the Fund's
            next post-effective amendment to its registration statement, but
            will not be offered initially and will not have ticker symbols as a
            result. A version of the Prospectus containing Class AB and
            Institutional Class, which will be offered initially, will be filed
            under Rule 497.

Comment 4:  We note that the facing page for Exchange Reserves indicates a
            request that the filing go automatically effective 60 days after
            filing. However, the bracketed date of the Prospectus reflects a
            delayed effective date in July 2016. Please note that the filing
            will be considered deficient if current financial information is not
            added to the Prospectus before the July date. For example, the
            Prospectus should incorporate financial highlights for the year
            ended April 30, 2016, the SAI should incorporate by reference the
            April 30, 2016 financial statements, and applicable SAI disclosures
            should reflect information as of the most recent fiscal period.

Response:   The Prospectus will be revised in response to this comment.

Prospectus
----------

Summary Information
-------------------

Comment 5a: Fees and Expenses of the Fund: Please define the term "AB Mutual
            Funds" as used in the narrative introduction paragraph.
            Alternatively, this term can be defined in the cross-referenced
            section on page 11 of the Prospectus.

Response:   The Prospectus will be revised in response to this comment.

Comment 5b: Fees and Expenses of the Fund: We note that page 11 of the
            Prospectus states: "Your investment will, however, be subject to a
            sales charge upon exchange of your Class A shares for the Class A
            shares of other AB Mutual Funds with sales charges." We note that
            there is no line item for such sales charge in the fee table. Please
            add a footnote stating the sales charge that may be imposed upon
            exchange into the Class A shares of other AB Mutual Funds.

Response:   The Prospectus will be revised to disclose in a footnote that a
            sales charge of up to 4.25% may be imposed upon an exchange of Class
            A shares for the Class A shares of other AB Mutual Funds with sales
            charges.

Comment 6:  Principal Strategies: In the first sentence of the third paragraph
            in the section "Principal Strategies" please insert the phrase "plus
            borrowings for investment purposes" in between the words "assets"
            and "in U.S. Government securities". This change should also apply
            to the first sentence of the third paragraph under the section
            "Investment Objective, Policies and Restrictions" in the SAI and the
            second paragraph under the section "Investment Objective, Policies
            and Restrictions--Fund Policies" in the SAI. The requested change is
            consistent with the Names Rule.

Response:   We do not believe that the technical definition of "assets" used in
            Rule 35d-1, which includes "borrowings for investment purposes"
            needs, or is required, to be disclosed in the 80% policy and will
            not revise the Prospectus in response to this comment.

Comment 7a: Bar Chart: With respect to Exchange Reserves, we note that the
            introductory sentence to the bar chart states that the annual
            returns in the bar chart for Class A shares do not reflect sales
            loads. Please add disclosure stating that if sales loads were
            reflected, returns shown would be lower.

Response:   The introductory sentence will be revised to remove the reference to
            sales loads, as sales loads are not imposed on purchases of Class A
            shares of the Fund.

Comment 7b: Bar Chart and Performance Information: Please provide the entire
            introductory narrative required by Item 4(b)(2)(i) of Form N-1A
            relating to comparison to a broad measure of market performance.

Response:   The Staff has stated that a money market fund need not compare its
            performance to a broad-based securities market index (see Letter to
            Craig S. Tyle, Esq., General Counsel, Investment Company Institute,
            from Barry D. Miller, Associate Director, Division of Investment
            Management, Securities and Exchange Commission (October 2, 1998)).
            The Prospectus will not be revised in response to this comment.

Comment 7c: Bar Chart and Performance Information: Please include in the
            performance table the returns of an appropriate broad-based
            securities market index as provided in Item 4(b)(2)(iii).

Response:   Please see response to Comment 7b.

Comment 7d: Bar Chart and Performance Information: Please remove the reference
            to "after taxes" in the second paragraph in the section "Bar Chart
            and Performance Information".

Response:   The Prospectus will be revised in response to this comment.

Investing in the Portfolio
--------------------------

Comment 8:  With respect to Government STIF, in the section "How to Buy
            Shares--Other Purchase Information" the prospectus states,
            "[p]urchase of the Portfolio's shares will be made only in full
            shares." Please disclose what happens to any amounts received in
            purchases, exchanges or reinvestments of dividends that are in
            excess of the full share amount. If the Fund keeps these excess
            amounts, please explain the legal basis for doing so.

Response:   The Prospectus will be revised to remove the disclosure quoted in
            Comment 8. Purchases of the Portfolio's shares may be made in full
            or fractional shares.

Comment 9:  The section "How to Sell or Redeem Shares--By Telephone" states that
            "[r]edemption requests by electronic funds transfer or check may not
            exceed $100,000 per Fund account per day." Please briefly disclose
            how a shareholder could redeem more than $100,000 in this situation
            when restricted to a $100,000 redemption by telephone.

Response:   A shareholder may redeem more than $100,000 per Fund account per day
            if the shareholder provides a signed letter of instruction or a
            redemption authorization form, accompanied by a signature guarantee
            from a bank, a member firm of a national stock exchange or another
            eligible guarantor institution. This process is described under
            "Investing in the Fund--How to Sell or Redeem Shares--Selling Shares
            Directly to the Fund by Mail". The Prospectus will not be revised in
            response to this comment.

Comment 10: Please clearly disclose whether the adopted policies and procedures
            on frequent purchases and redemptions of Fund shares apply to the
            Fund or if they do not apply to money market funds. If they do not
            apply to the Fund, please make this clear in the disclosure.

Response:   The policies on frequent purchases and redemptions of fund shares
            apply to money market funds, such as the Fund. Consequently, a short
            form description of the policies has been included in the Prospectus
            and a more detailed description has been included in the SAI. The
            Prospectus will not be revised in response to this comment.

SAI
---

Comment 11: Fundamental and Non-Fundamental Investment Policies: Please provide
            additional disclosure relating to the Investment Company Act of 1940
            and applicable laws that describes the limitations on the Fund's
            investments in greater detail.

Response:   The Fund believes the disclosure appropriately reflects the Fund's
            fundamental and non-fundamental investment policies as approved by
            the Fund's Board of Directors/Trustees and the SAI will not be
            revised in response to this comment.

Comment 12: Please reconcile the detailed disclosure on "Frequent Purchases and
            Sales of Fund Shares" in the SAI with the short disclosure on this
            topic in the Prospectus.

Response:   Please see response to Comment 10. The SAI will not be revised in
            response to this Comment.

Comment 13: Please confirm that the taxation section is accurate and current.

Response:   The taxation section is accurate and current as of the date hereof.

Comment 14: Please revise the Proxy Voting Policy Statement attached as Appendix
            A to provide more details on the actual policies used by the Adviser
            in accordance with the requirements of Item 17(f) of Form N-1A.

Response:   Item 17(f) of Form N-1A requires that a fund "describe the policies
            and procedures that the fund uses to determine how to vote proxies
            relating to portfolio securities . . . " The item permits (but does
            not require) a fund to satisfy this requirement by including a copy
            of the policies. We note that this requirement applies also to
            shareholder reports. We believe the description provided in the SAI
            meets the requirements of Item 17(f) of Form N-1A.

            form of Edgar correspondence prior to the effective date of the
            filing.

the Fund is responsible for the adequacy and accuracy of the disclosures in its
filing; (ii) Staff comments or changes to disclosure in response to Staff
