Willis Group Reports First Quarter 2005 Results

    NEW YORK--(BUSINESS WIRE)--April 27, 2005--Willis Group Holdings
Limited (NYSE: WSH), the global insurance broker, today reports
results for the quarter ended March 31, 2005. Net income for the
quarter ended March 31, 2005 after regulatory settlements and related
expenses, severance costs and other provisions was USD72 million, or
USD0.43 per diluted share, compared with USD148 million, or USD0.87
per diluted share, a year ago. Total reported revenues rose 1 percent
to USD669 million for first quarter 2005.
    The results of the first quarter were affected by the following
significant developments:

    --  On April 8, 2005, Willis announced agreements with the New
        York Attorney General, New York Department of Insurance and
        the Minnesota Attorney General to resolve issues raised by the
        industry-wide investigation into contingent commissions. The
        Company agreed to establish reimbursement funds totaling USD51
        million, and also recorded USD9 million in legal and
        administrative expenses in relation to the settlements (USD36
        million, or USD0.21 per diluted share, after tax).

    --  The Company continues to review its expense base in light of
        an evolving business model for insurance brokerage; as of
        March 31, 2005, approximately 500 positions were identified
        and are being eliminated. Severance costs and related expenses
        were recorded in the amount of USD28 million (USD19 million,
        or USD0.11 per diluted share, after tax).

    --  Based on the quarter-end review of current legal proceedings,
        the Company increased its provision for claims by an
        additional USD20 million (USD14 million, or USD0.08 per
        diluted share, after tax).

    --  Total volume and profit-based contingent commissions relating
        to 2004 arrangements outside the United States totaled USD3
        million in the quarter ended March 31, 2005 compared with
        USD21 million a year ago. These fees were abolished in 2004
        and will continue to run off. The decline in volume and
        profit-based contingent commissions reduced organic revenue
        growth by 3 percent. Other market remuneration declined to
        USD3 million in the quarter compared with USD22 million for
        first quarter 2004. We continue to work with the insurance
        markets to restructure the existing relationships and
        anticipate recovering a portion of these fees over time. The
        decline in other market remuneration reduced organic revenue
        growth by 3 percent.

    "We have confronted and put behind us a number of issues during
the first quarter. The resulting changes we are embracing in our
business model define this transitional period in the new world of
insurance," said Joe Plumeri, Chairman and Chief Executive Officer.
"We are challenging our own conventions and assumptions in order to
reinforce our business around the world and are confident we will
emerge with a stronger more resilient model for long-term success."

    Financial Results

    Total reported revenues for the quarter ended March 31, 2005
increased 1 percent to USD669 million, from USD665 million for the
same period last year. The effect of foreign currency translation
increased reported revenues 2 percent and net acquisitions added 3
percent.
    Organic revenue growth excluding volume and profit-based
contingent commissions and other market remuneration was 2 percent in
the first quarter, comprised of approximately 4 percent in net new
business and a negative 2 percent impact from declining insurance
premium rates and other market factors.
    "We are pleased with the revenue growth this quarter, in spite of
the continued decline in insurance premium rates across most lines and
challenging market conditions," Plumeri noted. "Our recruiting efforts
continue to yield success as we add recognized professionals to the
Willis team, and together have welcomed many new clients."
    Reported operating margin was 14.1 percent. Excluding regulatory
settlements and related expenses, severance costs and other
provisions, adjusted operating margin was 30.2 percent for the first
quarter of 2005 compared with 35.5 percent for the same period last
year. The decline in adjusted operating margin was primarily
attributable to the elimination of volume and profit-based contingent
commissions, the decline in other market remuneration and incremental
hiring expenses.

    Other

    At March 31, 2005, total long-term debt was USD450 million and
total stockholders' equity was approximately USD1.5 billion. The
capitalization ratio (total long-term debt to total long-term debt and
stockholders' equity) was 23 percent at March 31, 2005. The Board of
Directors has approved a new buy back program for USD300 million; this
replaces the previous program under which USD339 million was
purchased.
    During the first quarter, the Company completed four acquisitions
with annual revenues of approximately USD14 million. On April 14,
2005, the Company completed the sale of Stewart Smith, our wholesale
unit, with total reported revenues of USD77 million in 2004. There was
approximately USD113 million of immediately available cash at March
31, 2005, providing significant financial flexibility to support the
cash needs of the Company.
    "The entire insurance industry is undergoing sweeping
transformations. This changing environment brings challenges but many
more opportunities which we face with excitement and confidence," said
Plumeri.

    Definitions of Non-GAAP Financial Measures:

    We believe that investors' understanding of the Company's
performance is enhanced by our disclosure of the following non-GAAP
financial measures. Our method of calculating these measures may
differ from those used by other companies and therefore comparability
may be limited.

    Adjusted operating income

    Our first quarter 2005 results were significantly impacted by the
charges for regulatory settlements and related expenses, severance
costs and other provisions. We believe that excluding these items from
operating income, along with the GAAP measures, provides a more
complete and consistent comparative analysis of our results of
operations.

    Organic revenue growth

    Organic revenue growth excludes the impact of foreign currency
translation and acquisitions and disposals from reported revenues. We
use organic revenue growth as a measure of business growth generated
by operations that were part of the Group at the end of the period.

    Adjusted Operating Income:

    Adjusted operating income is defined as operating income excluding
charges for regulatory settlements and related expenses, severance
costs and other provisions. Operating income is the most directly
comparable GAAP measure, and the following table reconciles adjusted
operating income to operating income for the quarters ended March 31,
2005 and 2004:

Organic revenue growth is defined as revenue growth excluding the
