On Thursday, Wells Fargo revealed that an independent review of the company's records found that an additional 1.4 million potentially unauthorized accounts were created as the bank's employees scrambled to meet lofty sales goals. The bank had conducted an internal review of its accounts after revealing the fake account scandal last year. The new, external estimate covered a wider window of time than the bank's review and increases the initial tally by 67 percent; nearly 3.5 million unauthorized accounts are now thought to have been opened between 2009 and 2016.
