A high-profile former member of the Public Company Accounting Oversight Board has provided a frank glimpse into the bureaucratic clashes over Auditing Standard No. 5โ€”including revelations that the Securities and Exchange Commission fought aggressively to gut AS5โ€™s main provisions.

In an exclusive interview with Compliance Week, Kayla Gillan says the SEC โ€œpushed, pushed, pushed, and really tried very hard to get something different than what [the PCAOB] ended up producing.โ€ The Commission lobbied so hard to eliminate the central requirement that auditors examine a companyโ€™s internal controlsโ€”a provision the PCAOB ultimately retainedโ€”that Gillan feared the PCAOBโ€™s role under Sarbanes-Oxley might be undermined.
