Montgomery Asset Management LLC of San Francisco plans to close one of its funds to new investors by June 30.
The Montgomery Global Long-Short Fund is being closed to maintain a "steady inflow of assets" and to avoid its being flooded with new money, a spokesman said.
"Closing the fund doesn't mean we're going to be closing it forever," he added.
The fund was begun Jan. 1, 1998, and has about $100 million of assets under management, the spokesman said. It is one of 19 no-load Montgomery Funds, which have a total of about $4.5 billion of assets under management.
Montgomery Asset Management is a unit of Commerzbank Group, a $350 billion-asset banking company based in Frankfurt. The firm manages about $9 billion of assets.
