Six employees at KPMG were fired after an internal probe into a leak, the accounting firm said Tuesday.
The Wall Street Journal reported that a KPMG employee received "improper advance warnings" of inspections and shared it with executives. The newspaper said the firm notified the Securities and Exchange Commission and the Public Company Accounting Oversight Board when KPMG learned about the leak.
KPMG Chairman and CEO Lynne Doughtie told the Journal that the firm has "zero tolerance for such unethical behavior."
The accounting board is tasked with auditing the performance of major firms.
Correction: This story has been corrected to reflect that the six people were fired after an internal investigation of an issue that was flagged by a KPMG employee to management. It has also been updated to reflect that regulators were brought in by management.
