Operating cash earnings for the fourth quarter, or net income excluding goodwill amortization, a non-cash charge for performance-based stock options and non-recurring items, rose 172% to $49 million, or $0.30 per diluted share, compared to $18 million, or $0.15 per diluted share, in the corresponding period a year ago. Operating cash earnings for the year rose 172% to $147 million, or $0.99 per diluted share, compared with $54 million, or $0.45 per diluted share, a year ago. Organic revenue growth, excluding the effects of foreign exchange, acquisitions and disposals, was 14% for the quarter ended December 31, 2001. Reported revenues increased 11% in the fourth quarter to $387 million. EBITDA margin, or revenues less general and administrative expenses to total revenues, rose to 30% for the fourth quarter from 20% last year. Joe Plumeri, Chairman and Chief Executive Officer said, "Our performance confirms Willis' status as a premier global broker and client advocate. Despite challenging market conditions -

marked by reduced capacity, tighter underwriting terms and significant premium rate increases - Willis continues to negotiate this environment successfully on behalf of our clients. In turn, we are benefiting from heightened demand for brokerage and other risk management services." Organic revenue growth, excluding the effects of foreign exchange, acquisitions and disposals, was 12% for the year ended December 31, 2001, up from 8% in 2000. Controllable expenses on that same basis, or general and administrative expenses less incentives, were flat compared to 2000. Reported revenues were $1.4 billion, up 9% from a year ago, while reported general and administrative expenses declined 1% to $1.1 billion. EBITDA margin rose to 26% for the full year compared to 19% in 2000. At December 31, 2001, total long-term debt was $787 million, down 36% from $1.2 billion, including preference shares, a year ago. In addition to using most of the proceeds from the June 12, 2001 initial public offering to repay all the $273 million preference shares outstanding, Willis has made substantial long-term debt repayments from its operating cash flow. The next mandatory debt payment is not due until November 2005. Joe Plumeri commented, "Our significant earnings, strong cash flow and proceeds from the initial public offering have allowed us to reduce our long-term debt and preference shares by more than $400 million, which yields an annual after tax savings of more than $30 million. Willis continues to have tremendous financial flexibility." Willis recently completed three transactions consistent with its acquisition strategy. The company acquired Goldman Insurance Services of San Francisco, California on December 31, 2001. As of year end, Willis increased its majority interest in subsidiary Willis Italia. And, as of January 1, 2002, Willis acquired a majority ownership of associate, Jaspers Wuppesahl Industrie Assekuranz GmbH & Co KG (renamed Willis GmbH), Germany's third largest broker. Reported net income for the quarter ended December 31, 2001 was $27 million, or $0.16 per diluted share, compared with $5 million, or $0.04 per diluted share, for the same quarter last year. Reported net income included a non-cash charge for performance stock options of $13 million ($11 million, after tax). It also included a $5 million loss on disposal, including a goodwill writeoff related to the restructure of Willis Italia during the quarter, as we disposed of part of the business and increased our ownership of this subsidiary to 66.7% from 50.1%. The 2001 non-cash charge for performance stock options was $158 million ($132 million, after tax). As previously disclosed, this charge recognizes performance-based options granted to management by the Board of Directors as part of the 1998 buyout arrangement with KKR, for meeting or exceeding 2001 and 2002 targets. The cumulative charge represents approximately 68% of the total estimated charge based on the 2001 year-end stock price. The remaining performance stock option charge will be calculated according to the vesting schedule and any change in the stock price during 2002, and will be recognized quarterly through 2004. Joe Plumeri concluded, "Willis' operating results for 2001 clearly demonstrate that we can grow revenues while managing expenses, thereby expanding margins and improving profitability. We are building a great company. We are the only pure global insurance broker, have a clear vision, and are successfully building a sales culture to execute our growth strategy in all market conditions."
