Ladies and Gentlemen:

We have acted as counsel for AB Bond Fund, Inc., a Maryland corporation (the "Company"), in connection with the registration under the Securities Act of 1933, as amended (the "Securities Act"), of an indefinite number of shares of Advisor Class Common Stock (the "Class") of the AB Performance Fee Series – International Bond Portfolio, a portfolio of the Company (the "Portfolio"), par value per share $.0001 per share (the "Shares").  The Company is registered under the Investment Company Act of 1940, as amended, as an open-end management investment company.

As counsel for the Company, we have participated in the preparation of the Post-Effective Amendment to the Company's Registration Statement on Form N-1A to be filed with the Securities and Exchange Commission (the "Commission") to become effective on March 14, 2017, pursuant to paragraph (b) of Rule 485 under the Securities Act (as so amended, the "Registration Statement") in which this letter is included as Exhibit (i).  We have examined the Charter and By-laws of the Company and applicable amendments and supplements thereto and have relied upon such corporate records of the Company and such other documents and certificates as to factual matters as we have deemed to be necessary to render the opinion expressed herein.

Based on such examination, we are of the opinion that the Shares to be offered for sale pursuant to the Registration Statement are, to the extent of the number of Shares of the Class of the Portfolio authorized to be issued by the Company in its Charter, duly authorized, and, when sold, issued and paid for as contemplated by the Registration Statement, will have been validly issued and will be fully paid and non-assessable under the laws of the State of Maryland.

Members of this firm are admitted to the bars of the State of New York and the District of Columbia.

We hereby consent to the filing of this opinion with the Commission as an exhibit to the Registration Statement and to the reference to our firm under the caption "General Information--Counsel" in Part B thereof.

Very truly yours,
