Washington's business community was shocked on March 21 with the announcement that Carleton M. Stewart was out as chairman of American security after just four years in the position, following a long career with Citicorp of New York. After reaching an apparent impasse with the board of directors on his management stye (aloof and cold but very competent was the consensus) Stewart departed and was replaced immediately by Moody, American Security's president for more than seven years. Moody has promised to make his bank more community-oriented after a period under Stewart when ASB emphasized international business, national corporate lending and vast expansion of D.C. retail banking. Among recent developments under Stewart, ASC organized an insurance brokerage subsidiary; won approval for an Edge Act bank in Miami and made plans for a new trust business in Florida; expanded loan production offices to Cincinnati and Birmingham and increased its D.C. offices to 35 (the most of any bank here).
