Seymour Liebman, executive vice president and general counsel of Canon U.S.A., will now serve as senior managing executive officer of the parent company. He had been managing executive officer.

A Canon U.S.A. spokeswoman said last week that Adachi, Liebman and other top executives are reviewed annually on their job performance. If promotions are warranted, they are discussed and announced at the Canon Inc. shareholders meeting, which took place last month.

“These appointments represent that the members not only have responsibilities in their respective regions, but also have global responsibilities,” said spokeswoman Melissa Moritz.

She said Adachi and Liebman’s responsibilities at Canon U.S.A. remain unchanged.
