                            AMG REPORTS FINANCIAL AND
                    OPERATING RESULTS FOR FIRST QUARTER 2002

               COMPANY REPORTS CASH EPS FOR FIRST QUARTER OF $1.08

BOSTON, MA, APRIL 24, 2002 - Affiliated Managers Group, Inc. (NYSE: AMG) today
reported its financial and operating results for the quarter ended March 31,
2002.

Cash earnings per share ("Cash EPS") for the first quarter of 2002 were $1.08.
(Cash EPS is the Company's reported EPS figure plus the non-cash charges on a
per share basis for depreciation and amortization and deferred taxes related to
intangible assets which arise from the use of the purchase method of accounting.
The Company considers Cash EPS to be the most meaningful measure of its
financial performance.) Diluted earnings per share for the first quarter of 2002
were $0.63, and net income for the first quarter was $14.5 million. Cash Net
Income (net income plus the non-cash charges for depreciation and amortization
and deferred taxes related to intangible assets) was $24.7 million. These
operating results reflect changes in the accounting for intangible assets as a
result of the implementation of Financial Accounting Standard No. 142 in the
first quarter of 2002, and therefore are not directly comparable to operating
results for the first quarter of 2001. For the first quarter of 2002, revenue
was $119.3 million, compared to $100.5 million for the first quarter of 2001.
EBITDA for the first quarter of 2002 was $35.4 million, compared to $31.3
million for the same period of 2001.

The aggregate net client cash flows from directly managed assets for the first
quarter were approximately $225 million, while outflows of overlay assets were
approximately $444 million. These aggregate net client cash flows for the
quarter resulted in a net increase of approximately $2.0 million to AMG's
annualized EBITDA. The aggregate assets under management of AMG's affiliated
investment management firms at March 31, 2002 were $81.4 billion.

"We are pleased with our Affiliates' results, particularly in the face of
continued volatility in the equity markets," stated William J. Nutt, Chairman
and Chief Executive Officer. "The breadth and diversity among our Affiliates'
approximately 150 investment products has provided stability to AMG's earnings
and, with our EBITDA generated almost evenly in the high net worth, mutual fund
and institutional distribution channels, we are well positioned for continued
growth. In addition, AMG continues to benefit from our balanced exposure to
value and growth equity investment styles."

"Especially notable were the results of the small- and mid-cap products of our
value-oriented Affiliates, such as Tweedy, Browne, Systematic and Skyline, who
had strong performance and solid cash flows for the quarter," stated Sean M.
Healey, President and Chief Operating Officer. "Our Affiliate Development team
continues to identify opportunities for Affiliates to expand their product
offerings and broaden their distribution. In addition to the successful launch
of our multi-Affiliate diversified portfolios, we are working with a number of
Affiliates on new collective distribution initiatives. Finally, we are pleased
with our progress toward executing investments in additional growing, high
quality mid-sized investment management firms."

AMG is an asset management company with equity investments in a diverse group of
mid-sized investment management firms. AMG's strategy is to generate growth
through the internal growth of its existing Affiliates, as well as through
investments in new Affiliates. AMG's innovative transaction structure allows
individual members of each Affiliate's management team to retain or receive
significant direct equity ownership in their firm while maintaining operating
autonomy. In addition, AMG provides centralized assistance to its Affiliates in
strategic matters, marketing, distribution, product development and operations.
