On August 23, 2017, BankUnited, Inc. (the "Company") filed a Current Report on Form 8-K (the "Prior Report") reporting the appointment of Mr. William S. Rubenstein, Esq. as a member of the Board of Directors (the "Board") of the Company, effective August 23, 2017.  The Prior Report stated that Mr. Rubenstein had not been appointed to serve on a Board committee at that time and the committees to which Mr. Rubenstein may be appointed at a later date had not yet been determined.  Pursuant to Instruction 2 to Item 5.02 of Form 8-K, this Form 8-K/A is being filed to disclose that Mr. Rubenstein has been appointed to serve as a member of a new Risk Committee of the Board (the "Risk Committee"), which was separated from the Audit and Risk Committee effective November 29, 2017.

The Board established the Risk Committee as a new standing committee of the Board on November 29, 2017.  The purpose of the Risk Committee is to assist the Board in overseeing the Company's risk management framework and to ensure that the Company and BankUnited, N.A., a national bank and wholly owned subsidiary of the Company (the "Bank"), have appropriate policies and procedures related to risk identification, risk governance and risk reporting and maintain a risk control infrastructure that is consistent with the complexity of their business.  In addition to Mr. Rubenstein, the Board appointed Douglas J. Pauls (Chairman), Eugene F. DeMark and Sanjiv Sobti, Ph.D. to serve as members of the Risk Committee, effective November 29, 2017.

Item 8.01
Other Events.

Before the establishment of the Risk Committee, the Risk Committee's functions were generally performed by the Board's Audit and Risk Committee.  In connection with establishing the Risk Committee, the Board renamed the Audit and Risk Committee as the Audit Committee, effective November 29, 2017.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
