    Willis Group Reports Fourth Quarter and Full Year 2004 Results

    NEW YORK--(BUSINESS WIRE)--Feb. 9, 2005--Willis Group Holdings
Limited (NYSE:WSH), the global insurance broker, today reports results
for the quarter and year ended December 31, 2004.
    "Despite a declining rate environment and extraordinary challenges
facing the global insurance industry, we were able to continue growing
in 2004 and expanded revenues on an underlying basis by 4 percent for
the year," commented Joe Plumeri, Chairman and Chief Executive
Officer. "The recent addition of great new talent and clients to our
already strong platform makes us more enthusiastic than ever about the
future."

    Fourth Quarter and Year Ended December 31, 2004 Review

    The results for the fourth quarter of 2004 were affected by a
decline in volume and profit-related contingent commissions, following
the Company's decision to discontinue all agreements covering such
income. These contingent commissions declined $14 million pre tax,
compared to the fourth quarter of 2003.
    Consequently, net income for the quarter ended December 31, 2004
was $108 million, or $0.65 per diluted share, compared with $118
million, or $0.69 per diluted share, a year ago. Excluding non-cash
compensation for performance-based stock options and net gain on
disposal of operations, adjusted net income decreased 13 percent to
$104 million for the quarter ended December 31, 2004 from $119 million
in the same period last year, while adjusted net income per diluted
share fell 10 percent to $0.63 for the fourth quarter of 2004 from
$0.70 a year ago. Foreign currency translation decreased fourth
quarter 2004 reported earnings by $0.01 per diluted share compared to
a year ago.
    Net income for the year ended December 31, 2004 was $427 million,
or $2.54 per diluted share, compared to $414 million, or $2.45 per
diluted share, a year ago. Excluding non-cash compensation for
performance-based stock options, a related one-time tax benefit
arising from a change in UK tax legislation in 2003, net gain on
disposal of operations and a subordinated debt redemption premium,
adjusted net income for the year ended December 31, 2004 increased 13
percent to $437 million from $386 million in 2003, while adjusted net
income per diluted share rose 14 percent to $2.60 from $2.28 in 2003.
There was no net impact of foreign currency translation on reported
earnings for the year ended December 31, 2004 compared to a year ago.
    Total reported revenues for the quarter ended December 31, 2004
increased 2 percent to $588 million, from $577 million for the same
period last year. The effect of foreign currency translation reduced
reported revenues 4 percent and net acquisitions added 6 percent.
Included in total reported revenues for the fourth quarter were volume
and profit-based contingent commissions of $25 million compared with
$39 million in the comparable quarter last year. Excluding contingent
commissions, organic revenue growth was 3 percent in the fourth
quarter, comprised of approximately 7 percent net new business growth
and a negative 4 percent impact from declining insurance premium
rates.
    The adjusted operating margin was 28.1 percent for the fourth
quarter of 2004 compared with 33.6 percent for the same period last
year. The decline in contingent commissions accounted for
approximately 2 percent of the reduction in adjusted operating margin;
the remainder was attributed to higher expenses related to legal,
investigative and regulatory compliance, and incremental salaries and
benefits expense for recruiting and retention.
    Total reported revenues for the year ended December 31, 2004
increased 10 percent to $2,275 million, up from $2,076 million for the
corresponding period in 2003. The effect of foreign currency
translation increased reported revenues 2 percent and net acquisitions
added 4 percent. Included in total reported revenues for 2004 were
volume and profit-based contingent commissions of $71 million in 2004
compared to $70 million in 2003. Excluding contingent commissions,
organic revenue growth was 4 percent, comprised of approximately 6
percent net new business growth and a negative 2 percent impact from
declining insurance premium rates. The adjusted operating margin was
29.3 percent for the year ended December 2004, compared with 30.3
percent the previous year.
    "Even though we are in a transition as we continue to build for
the future, we have good momentum heading into 2005," commented Joe
Plumeri, Chairman and Chief Executive Officer. "We are in a good
position and will do all we can to make it better. Everything we have
done or are doing is designed to make sure we have the best people and
the best processes to attract and look after our growing list of
clients."

    Balance Sheet

    At December 31, 2004, total long-term debt was $450 million and
total stockholders' equity was approximately $1.4 billion. The
capitalization ratio (total long-term debt to total long-term debt and
stockholders' equity) was 24 percent at year-end December 31, 2004.

    Share Buybacks and Acquisitions

    For the year ended December 31, 2004, the Company repurchased 9.3
million shares for $339 million under the Company's $500 million
authorization. Buyback activity in the fourth quarter was modest at
0.3 million shares for $12 million. There was approximately $222
million of immediately available cash at December 31, 2004, providing
significant financial flexibility to support the cash needs of the
Company.
    In 2004, the Company completed 10 acquisitions with annual
revenues of approximately $155 million, including the acquisitions of
Coyle Hamilton, the Republic of Ireland's largest privately owned
insurance broker, and Opus and Jeffries which strengthened our middle
market and large account capabilities in the United Kingdom.

    Taxes

    Excluding the effects on taxation of amortization of intangibles,
disposals of operations, performance-based stock options and the
one-time tax benefit in 2003 that arose from a change in UK
legislation, the underlying tax rate for 2004 was 33 percent, compared
to 34 percent for 2003.

    Conference Call

    The Company will discuss financial results and outlook on a
conference call scheduled for 8:00 a.m. Eastern Time, February 10,
2005. This call is being webcast and can be accessed at

Note 1: Non-Cash Compensation - Performance Options

As of December 31, 2004, the Company had recognized 100 percent of
the $270 million non-cash compensation charge for performance-based
stock options granted to management as part of the 1998 leveraged
buyout arrangement for meeting or exceeding 2001 and 2002 targets.

Note 2: Income tax expense

Following a change to UK legislation regarding the taxation of
employee stock options, a one-time tax benefit of $37 million was
recognized in the third quarter of 2003.

                              (unaudited)

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.

Organic revenue growth

Organic revenue growth excludes the impact of foreign currency
translation and acquisitions and disposals from reported revenues. We
use organic 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 and adjusted net income

Because the non-cash compensation charge for performance-based
stock options was based on our stock price at the end of each quarter
until December 31, 2002, changes in our stock price increased the
volatility of our reported operating income and reported net income.
The net gain or loss on disposal of operations, together with the
non-recurring subordinated debt redemption premium in 2004 and
one-time tax benefit relating to employee stock options in 2003, also
impact the volatility of our reported results. We believe that
excluding these items from the following non-GAAP measures, along with
the GAAP measures, provides a more complete and consistent comparative
analysis of our results of operations.

Adjusted Operating Income:

Adjusted operating income is defined as operating income excluding
non-cash compensation for performance-based stock options and net gain
or loss on disposal of operations. Operating income is the most
directly comparable GAAP measure, and the following table reconciles
adjusted operating income to operating income for the quarters and
years ended December 31, 2004 and 2003:

Adjusted Net Income:

Adjusted net income is defined as net income excluding non-cash
compensation for performance-based stock options, net gain or loss on
disposal of operations and the non-recurring subordinated debt
redemption premium in 2004 and the one-time tax benefit relating to
employee stock options in 2003. Net income is the most directly
comparable GAAP measure, and the following table reconciles adjusted
net income to net income for the quarters and years ended December 31,
2004 and 2003:

Organic revenue growth and volume and profit-based contingent
commissions:

Organic revenue growth is defined as revenue growth excluding the
impact of foreign currency translation and acquisitions and disposals.
The percentage change in reported revenues is the most directly
comparable GAAP measure, and the following table reconciles this
change to organic revenue growth by business unit for the year ended
December 31, 2004.

The table also discloses organic revenue growth excluding volume
and profit-based contingent commissions which are summarized in the
second table. Following our announcement in October 2004 that we were
abolishing volume and profit-based contingent commissions, we believe
that separate disclosure of these revenues will enhance investors'
understanding of our performance in 2004.
