The long-time CEO of Wells Fargo agreed on Tuesday to forfeit $41 million (NZ$56.3m) in performance pay three weeks after the bank acknowledged that for at least five years thousands of low-level employees allegedly set up sham accounts to meet sales quotas.
The San Francisco-based bank has repeatedly apologized for the scheme and said it had fired 5,300 employees for bad behavior and put in place more stringent internal controls.
But that hasn't been enough for lawmakers who have been pushing for the company's top leaders to give back the millions in bonuses they earned while the misconduct was occurring.
The independent directors of the Wells Fargo board announced Tuesday that they were launching an investigation into the Wells Fargo's retail business.
"We are deeply concerned by these matters, and we are committed to ensuring that all aspects of the Company's business are conducted with integrity, transparency, and oversight," Stephen Sanger, the lead independent director, said in a statement.
