EXHIBIT INDEX Exhibit No. Description - ----------- ------------------------------- 99.1 Press Release of WGHL dated February 15, 2005

                                                                    Exhibit 99.1

                      Willis Group Divests Wholesale Unit;
                  American Wholesale Buys Stewart Smith Group

    NEW YORK--(BUSINESS WIRE)--Feb. 15, 2005--Willis Group Holdings
(NYSE: WSH), the global insurance broker, and American Wholesale
Insurance Group, Inc (AmWINS), the largest independent wholesale
insurance broker in North America, announced today that AmWINS will
acquire Stewart Smith Group, Willis' U.S. wholesale unit. Terms of the
transaction were not disclosed. It is expected to close at the end of
the first quarter.
    "For several years now, we have emphasized our focus on our core
retail broking operations," said Joe Plumeri, Chairman and CEO of
Willis. "Part of this overall strategy included divesting our third
party claims administration businesses, personal finance units and
other non-core business interests. Over the last few years, we have
made a number of acquisitions around the world and have increased our
ownership in several of our affiliates which were not wholly-owned
where doing so strengthened our retail network and our specialty
businesses.
    "Today, staying true to our mission and focusing our attention and
resources on growing our retail operations, we are announcing the sale
of Stewart Smith to American Wholesale," Plumeri continued. "In
American Wholesale, we have found a dynamic company committed to this
important sector of our industry. In only three years, their team has
built one of the most respected wholesale organizations in the
country."
    Stewart Smith writes hard-to-place, unique, and specialty
coverages. Headquartered in New York, Stewart Smith has 13 branches
located in major cities across the country. Purchasing Stewart Smith,
a national wholesale insurance broker with approximately $900 million
in premium placements in 2004, will afford AmWINS greater
opportunities to develop relationships with national retail brokers
while diversifying the Charlotte-based company's product offerings,
geographic presence and distribution force. The Stewart Smith
acquisition will bring AmWINS' total premium placements to over $2.4
billion, making it the nation's second largest wholesale insurance
organization. Mark Smith, President and CEO of Stewart Smith, will
assume the role of President of the AmWINS Brokerage Division.
    "The acquisition of Stewart Smith will add even more top-tier
professional brokerage talent to the AmWINS team. Additionally, it
expands our geographic footprint in the Pacific Northwest, Midwest and
Southeast," said M. Steven DeCarlo, AmWINS President and Chief
Executive Officer. "Mark is one of the most respected leaders in the
insurance industry. His proven ability to deliver superior results
while building one of the finest wholesale insurance brokerage firms
makes him a natural to lead our largest division - AmWINS Brokerage.
In this role, Mark will oversee 30 branch offices and over 400
employees.
    "This acquisition strategically enhances our insurance brokerage
offerings to retail agents and brokers across the country. That said,
our new scale by no means replaces the importance of earning our
stripes each and every day - one account at a time," says DeCarlo.
American Wholesale has received a financing commitment for this
transaction from Credit Suisse First Boston.
