Willis Group Holdings Limited c/o Willis Group Limited 51 Lime Street London EC3M 7DQ, England August 24, 2009 VIA EDGAR - --------- Mr. Jeffrey Riedler Assistant Director Division of Corporate Finance United States Securities and Exchange Commission 100 F Street, NE Washington, D.C. 20549-3628 Re: Willis Group Holdings Limited Annual Report on Form 10-K for the fiscal year ended December 31, 2008 Definitive Proxy Statement filed March 13, 2009 File No. 001-16503 Dear Mr. Riedler, Below are the responses of Willis Group Holdings Limited (the "Company") to the comments of the staff of the Division of Corporate Finance (the "Staff") of the Securities and Exchange Commission ("SEC") set forth in that certain letter dated August 10, 2009 relating to the above mentioned Annual Report and Definitive Proxy Statement (the "Comment Letter"). For your convenience, the numbered paragraphs of this letter correspond to the numbered paragraphs of the Comment Letter. Capitalized terms not otherwise defined shall have the meaning ascribed to such term in the Company's 2009 Definitive Proxy Statement. Definitive Proxy Statement - -------------------------- Executive Compensation Components - --------------------------------- Annual Incentive Compensation, page 22 - -------------------------------------- 1. Comment: We note your response to comment 1 and reissue the comment. Although you have provided non-financial objectives for your executive officers on a collective basis you have not disclosed the individual objectives used to determine your executive officers' bonus payments for each executive officer, respectively. To the extent this information is known, please provide us with draft disclosure for your 2010 proxy statement which provides the following on an individual basis: 1o The performance objectives; o Confirmation that you will discuss the achievement of the objectives; and o A discussion of how the level of achievement will affect the actual bonuses to be paid. To the extent that the objectives are quantified, the discussion in your proxy statement should also be quantified. Response: Because it is not possible to predict the identities of the Company's 2009 named executive officers ("NEOs") which will affect the disclosure, for purposes of responding to the Staff's comment, the Company has assumed that the 2009 NEOs will be the same as the 2008 NEOs. The Company has omitted disclosure with respect to Mr. M.F. Crowley, who is no longer employed by the Company, and Mr. Joseph J. Plumeri, the Chairman and Chief Executive Officer, who does not participate in the annual incentive pool (the "AIP"). Mr. Plumeri's compensation is based upon the terms set forth in his employment agreement which is described in the Company's 2009 Definitive Proxy Statement under the section entitled "Compensation Tables--Chairman and Chief Executive Officer's Employment Agreement." As discussed with the Staff, because the 2008 incentive awards under the AIP were not allocated based on personal objectives and the 2009 incentive awards have not been determined at this time, the below disclosure is intended to serve as a general outline of how the Company expects to comply with the Staff's comment in its 2010 Definitive Proxy Statement. In its 2010 Definitive Proxy Statement, the Company will make all necessary changes to reflect the personal objectives used by the Compensation Committee to determine the 2009 incentive awards, including quantification of such objectives to the extent required (e.g., not subject to confidential treatment or other applicable exception). The Company confirms that in its 2010 Definitive Proxy Statement, it will discuss the achievement of the objectives by each NEO as well as how the level of achievement of the objectives by the NEO will affect the actual incentive bonus paid to him. Proposed Disclosure - ------------------- "In addition to the EBIT and revenue financial targets, [insert percentage] of the overall AIP pool for the Company's Executive Officers (other than the Chairman and Chief Executive Officer) is allocated based upon the Executive Officers' performance against non-financial objectives. In the case of the NEOs, these objectives included the following: Peter Hearn: o Achieving organic commissions growth; o Realizing benefits from the Company's Shaping our Future and Right Sizing Willis initiatives; o Implementing and communicating the new compensation program for the Associates in the Reinsurance business; and 2 o Providing sufficient feedback to Associates within the Reinsurance business. Grahame J. Millwater: o Developing and executing the Company's strategic plan for 2009, which includes revenue growth and the Company's Shaping our Future and Right Sizing Willis initiatives; o Supporting business leaders to realize financial targets and benefits from the Company's Shaping Our Future initiative; o Maintaining and growing the Company's client base; o Enhancing marketing and communications; and o Providing sufficient feedback to Associates.
