First American Bank, N.A., of Washington has announced the formation of two new operating divisions and the appointment of executive vice presidents to head them.

The new groups are the domestic banking group and the international and support services group, and their executive vice presidents are Robert S. Cherouny and Richard D. Barrett, respectively. In addition, George E. Flather Jr. was named executive vice president in charge of the trust division. All three will report to senior bank management through a senior executive vice president, a new position that will be filled by C. Jackson Richie Jr.

"This reorganization recognizes that we have expanded our operations over the past five years, and in so doing, have created a need for expanded top management," said Francis G. Addison III, chairman and chief executive officer of First American. "This new organizational structure will give us a better fix on our deposit and loan services, trust clients and internal support divisions so that we can more efficiently serve our growing customer base."

Cherouny has been with the bank since 1969. He was most recently senior vice president for loan administration. In his new position he will oversee the bank's retail, commercial and national banking divisions, real estate, business development and marketing.

Barrett has been with First American since 1970, most recently as director of the international division. He will continue to be responsible for that division and also will supervise the support services group, which consists of the planning and accounting, data processing, funds managment and operations division.

Flather has head the bank's trust department since 1970. He will retain that assignment and also will oversee the personal and corporate trust divisions.
