Global Asset Management Inc., Wayne, has filed a preliminary prospectus with the Securities and Exchange Commission for its plan to raise $200 million in an initial public stock offering.

The stock would be listed on the American Stock Exchange. Global Asset plans to acquire an alternative asset-management business, though "we do not have any specific business" in mind, according to the filing.

J. Paul Bagley, chairman of Fortune Management Inc., would serve as chairman, and Hamilton Lane founder Leslie A. Brun, a Fortune director, would serve as chief executive officer.

Brun is a board member and investor at Philadelphia Media Holdings L.L.C., which owns The Inquirer. Hamilton Lane provides private-equity asset-management services.
