Wells Fargo’s board said on Monday that it would claw back an additional $75 million in compensation from the two executives on whom it pinned most of the blame for the company’s scandal over fraudulent accounts: the bank’s former chief executive, John G. Stumpf, and its former head of community banking, Carrie L. Tolstedt.

The clawbacks — or forced return of pay and stock grants — are the largest in banking history and among the largest in corporate America. A four-person committee of Wells Fargo’s directors investigated the extensive fraud.

Wells Fargo’s board said in a report issued on Monday that Mr. Stumpf had turned a blind eye to the fraudulent accounts being created under his nose and that Ms. Tolstedt, who ran the branch system, had focused obsessively on sales targets and withheld information from her boss and the board.

Wells Fargo’s misdeeds, which came to light in September, have at least temporarily become a more widely recognized symbol of the bank than its signature stagecoach. Bankers across Wells Fargo’s giant branch system were tacitly encouraged to meet their sales goals by committing fraud; opening unwanted or unneeded accounts in customers’ names; and, sometimes, moving money into and out of the sham accounts.
