This Current Report on Form 8-K is filed by CBRE Group, Inc., a Delaware corporation (which we may refer to as “we”, “us”, “our” or the “Company”), in connection with the matters described herein:

(b), (c), (d), (e)

On May 15, 2012, the Company, CBRE, Inc. and Brett White, our chief executive officer, entered into a Transition Agreement in connection with Mr. White’s desire to retire on December 31, 2012. At our Board meeting on November 8, 2012, Mr. White reported that the planned leadership transition had been successfully completed over a month ahead of schedule. As a result, Mr. White requested that his retirement date be accelerated to midnight November 30, 2012 to allow Robert E. Sulentic, president of the Company, to assume the position of chief executive officer as of December 1, 2012. Our Board agreed and entered in to the record a resolution acknowledging Mr. White’s many years of service including almost eight years as our chief executive officer. All other terms in the Transition Agreement continue unchanged and in full force and effect. Mr. White will remain on our board of directors and as a member of its executive and acquisition committees.

The board of directors has appointed Mr. Sulentic to become our chief executive officer, effective December 1, 2012, consistent with the board’s intention previously disclosed in our current report on Form 8-K filed with the Securities and Exchange Commission on May 9, 2012. Also effective December 1, 2012, the board will be expanded to a size of 11 members and the board has elected Mr. Sulentic to fill this new vacancy. Information about Mr. Sulentic is incorporated by reference herein from our annual report on Form 10-K for the year ended December 31, 2011.
