Wells Fargo & Co. agreed to pay $480 million to settle a class-action lawsuit in which investors accused the bank of securities fraud related to its fake-account scandal. The settlement resolves the main class-action suit brought by shareholders targeting the bank's allegedly deficient disclosures related to its sales practices. It had previously set aside reserves for the settlement, according to a regulatory filing Friday. Wells Fargo said in a statement that it denies the allegations in the suit.
