Charles Scharf, Wells Fargo & Co.’s new CEO for the past four months, told a congressional panel Tuesday that the company has centralized its compliance work, made it independent of business units and added some 3,300 people to its compliance staff.

Scharf disappointed many members of the U.S. House Committee on Financial Services by refusing to put a timeline on bringing the bank into full compliance with five government consent orders related to various scandals, including one creating millions of fake bank accounts.
