And don't miss Stephen Gandel on Equifax's continuing woes: "In similar corporate scandals, outside firms have led the investigation. Instead, Equifax's is being conducted by members of the board, although they have hired a separate law firm. Worse, two of the three board members leading the investigation were also on the board's technology committee, which had the express responsibility of reviewing and monitoring the company's data-security efforts. Clearing executives of wrongdoing will also clear the board and in particular its technology committee."
