AMG Announces a Strategic Partnership with Hong Kong-based Value Partners Group Limited

BOSTON--(Business Wire)--
Affiliated Managers Group, Inc. (NYSE: AMG), a diversified asset management
company, has acquired a five percent stake in Value Partners Group Limited from
a group of senior management owners, including its Chairman and Chief Investment
Officer Cheah Cheng Hye, who is also a co-founder of the firm. In connection
with the investment, AMG and Value Partners have agreed to work together on
joint product development and strategic distribution opportunities, which
extends AMG`s global presence into the Asian marketplace.

Founded in 1993, Value Partners, which is listed on the Hong Kong Stock
Exchange, is one of the largest independent boutique asset management firms in
Asia, with approximately US$4.6 billion in assets under management as of
September 30, 2009. The firm is well known for its disciplined, value-based
investment approach, focusing on under-followed, under-researched stocks. Value
Partners follows a traditional Graham and Dodd value investing approach, placing
a strong emphasis on intensive research and bottom-up stock picking. One of the
pioneers of value investing in Asia, Mr. Cheah was named one of the 25 Most
Influential People in Asset Management in Asia by AsianInvestor in May 2009.
Value Partners has a strong and experienced senior investment team whose
coverage of Asian equities is regarded as one of the most comprehensive in the
industry. The firm, which employs 78 people, including 22 investment
professionals, manages a wide range of investment products for institutions,
individuals and corporate investors.

In addition to its long history of outstanding investment performance in its
core value strategies, Value Partners continues to identify opportunities to
further expand the scope of its business as well as the range of its product
offerings. Most recently, Value Partners entered into a joint venture agreement
with Ping An Insurance (Group) of China, which is also an equity investor in the
firm, to launch exchange-traded funds to meet rapidly growing customer demand in
China, Hong Kong and other Southeast Asian markets.

"Our investment in Value Partners marks our entry into the Greater China region,
and we are very pleased to partner with one of the largest and most respected
independent boutique asset management firms. With an outstanding reputation for
delivering superior returns for its clients, Value Partners has generated
impressive growth since its inception through a disciplined, deep value
investment strategy, as well as key business decisions that have expanded the
breadth and scale of its product offerings," stated Sean M. Healey, AMG`s
President and Chief Executive Officer. "We have identified a number of synergies
in product development and distribution, and will work together to develop
strategic initiatives that enhance our respective businesses. We are very
excited to partner with Mr. Cheah and his team, and we look forward to a strong
and growing partnership."

"We are impressed by AMG`s partnership approach, as well as their expertise in
product distribution and development on a global scale," stated Mr. Cheah.
"Given its partnerships with a number of the industry`s leading boutique
investment management firms, including highly regarded value managers, we see a
broad range of exciting opportunities to leverage both our core competencies and
complementary product offerings on a number of joint initiatives."

As part of its global distribution platform, AMG expects to open a sales and
marketing office in Hong Kong in 2010. In addition to its U.S. distribution
capabilities, AMG currently has dedicated sales and marketing offices in London,
serving investors in Europe and the Middle East, as well as Sydney, serving
institutional investors in Australia and New Zealand.
