Molson Breweries USA Inc., the American distribution subsidiary of Canada's largest beer manufacturer, is moving its headquarters to Reston.

The move, scheduled for Aug. 20, will combine the company's offices in Baltimore and North Hills, N.Y. Molson plans to lease all 21,000 square feet of the top floor of One Fountain Square in the new Reston Town Center development.

A total of 45 employees, eight fewer than now work at the Baltimore and North Hills offices, will occupy the new headquarters. The job cuts are intended to eliminate duplicated efforts, said John Barnett, president and chief executive of Molson Breweries USA.

Molson Breweries USA's move is the latest in a series of deals for the developers of the Reston Town Center, which has aggressively courted local firms and out-of-state companies seeking to move to the Washington area.

The developers last September signed Rolls-Royce Inc., the U.S. branch of the British aerospace firm that had been based in Greenwich, Conn. Reston Town Center, which consists of a hotel, three office buildings, restaurants and stores, will open officially Oct. 18.

"Everything about Reston brought us here," Barnett said from his Baltimore office. "We looked at a number of sites from Atlanta to Boston. We wanted good airport services, a good environment in which our employees could both work and live, and an opportunity for the majority of our employees, especially those in New York, to have their paycheck go further."

Ken Wong, vice president and senior development officer for Reston Town Center Associates, which negotiated the lease with Molson Breweries USA, said, "This is a very significant coup for us and for the {metropolitan} marketplace because it confirms the continuing attractiveness of the Washington area for businesses."

Molson Breweries's Canadian parent is a subsidiary of Molson Companies Ltd., which last year acquired Elders IXL Ltd., Australia's largest company.

For the fiscal year ended March 31, Molson's earnings increased 35 percent, to $117.9 million from $87.1 million a year ago. Among the Canadian conglomerate's various holdings are the National Hockey League's Montreal Canadiens and the Vancouver Canadians, a minor-league baseball team in the Pacific Coast League.
