Promark Global Advisors is New Brand Identity of GM Asset Management

NEW YORK - In recognition of its growing client diversification, General Motors
Asset Management (GMAM) has changed its brand identity to Promark Global
Advisors, Inc. (Promark).

New York-based Promark manages over US$130 billion of assets,

managing investments for employee benefit funds for more than 60 years. The
Promark group includes Promark Investment Advisors, Inc., an SEC-registered
investment adviser, and Promark Trust Bank, N.A., an OCC-chartered bank.

“GM remains our largest client and we expect the company to continue to
be a vital part of our business,” said Nancy Everett, CEO of Promark Global
Advisors. “The experience gained through this relationship enables us to
bring a unique perspective and commitment to managing the plan assets of
other firms, a fact we are highlighting with the new brand.”

Promark is focused on managing pension plans using asset and liability
management solutions and developing customized investment programs for each
client, as well as providing investment management for specific mandates,
most notably alternative investments such as real estate and absolute-return
strategies.
