Item 4.01.                Change in Registrant’s Certifying Accountant.

As previously disclosed by GFI Group Inc. (the “Company”) on its Form 8-K filed February 27, 2012, on February 21, 2012, the Audit Committee of the Board of Directors of the Company engaged PricewaterhouseCoopers LLP (“PwC”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2012.  In connection with the engagement of PwC, on February 23, 2012, the Company informed Deloitte and Touche LLP (“D&T”) that it would be dismissed as the Company’s independent registered public accounting firm effective upon the filing of the Company’s Form 10-K for the 2011 fiscal year.

This Form 8-K/A amends the Form 8-K filed by the Company on February 27, 2012 to confirm that, upon D&T’s delivery of its Report of Independent Registered Accounting Firm dated March 15, 2012 in connection with the Company’s filing of its Annual Report on Form 10-K, D&T concluded the 2011 fiscal year audit for the Company and completed its engagement.

The reports of D&T on the Company’s consolidated financial statements for the past two fiscal years ended December 31, 2011 and 2010 contained no adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principle.

During the two most recent fiscal years and through March 15, 2012, there have been (i) no disagreements with D&T on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which  disagreements if not resolved to the satisfaction of D&T would have caused them to make reference thereto in their reports on the consolidated financial statements for such years and (ii) no reportable events (as defined in S-K 304(a)(1)(v)).

The Company has provided D&T a copy of the above disclosures and has requested that D&T furnish it with a letter addressed to the SEC stating whether or not it agrees with the above statements. A copy of such letter, dated March 20, 2012, is filed as Exhibit 16 to this Form 8-K/A.
