Wells Fargo, the nation's fourth-largest bank, agreed Friday to pay a $3 billion fine to settle a civil lawsuit and resolve a criminal prosecution filed by the Justice Department over its fake account scandal.

Under pressure to meet sales quotas, bank employees opened millions of savings and checking accounts in the names of actual customers, without their knowledge or consent. Since the fraud became public in 2016, the bank has faced a torrent of lawsuits. The scheme lasted more than a decade, Justice Department officials said, and was carried out by thousands of Wells Fargo employees.

As part of the settlement, Wells Fargo admitted that employees were pressured to sell large volumes of new products to existing customers as a way of generating more business, often with little regard for a customer's actual needs. Bank employees began calling the practice "gaming," and it included opening accounts without a customer's knowledge, issuing credit and debit cards, and moving money from existing accounts to the fraudulently opened ones.
