The Public Company Accounting Oversight Board (PCAOB) issued its 2019 annual inspection reports on Feb. 2 for the seven largest U.S. audit firms, including each of the Big Four, BDO, Grant Thornton, and RSM.
For the third year in a row, the best performance out of the Big Four came from Deloitte, with only 10.3 percent of its inspected audits having significant audit deficiencies. The firm was at 11.5 percent for 2018 after a Big Four-best 20 percent a year prior.
