U.S. Bancorp, the nation's largest regional lender, is giving board members more power to cancel bonuses if top executives aren't attentive enough to risks.

The new policies apply to restricted stock units and certain stock options that reward executive officers for their performance, the Minneapolis-based lender said Wednesday in a regulatory filing. Decisions on rescinding some or all of an executive's unvested awards will rest with the board's compensation and human resources committee.
