More Wells Fargo customers may have been affected by a scandal over phony accounts than previously believed, the third-largest U.S. lender said in a regulatory filing on Wednesday.
Wells Fargo had previously estimated that up to 2.1 million customers may have had checking and credit-card accounts opened in their names without authorization over a period of several years.
As part of an expanded review of affected customers, Wells said in its annual 10-K filing that there could be "an increase in the identified number of potentially impacted customers."
Wells initially disclosed the number of affected customers as part of a $185 million settlement in September, leading to multiple government probes, lawsuits and an internal review, and hurting Wells Fargo's reputation.
Thousands of employees were fired over customer abuses, which stemmed from aggressive sales targets implemented by managers. Wells's then-CEO John Stumpf abruptly left the bank because of the scandal.
