The announcement follows September's settlement between the Securities and Exchange Commission and the oilfield services firm Weatherford International, which the SEC fined $140 million for fraudulently lowering its year-end tax provisions.
The SEC said that Ernst & Young, one of the global "big four" accounting firms, had failed to detect the fraud for more than four years.
Craig Fronckiewicz, the Ernst & Young partner who coordinated the audits, and Sarah Adams, a former tax partner who was part of the audit team, both agreed to suspensions from handling the accounting of SEC-regulated firms to settle charges of having ignored "significant red flags" during the Weatherford audits and reviews, the SEC said in a statement.
"The audit team was aware of post-closing adjustments that Weatherford was making to significantly lower its year-end provision for income taxes each year, but it relied on Weatherford's unsubstantiated explanations instead of performing the required audit procedures to scrutinise the company's accounting," the SEC said in a statement.
Ernst & Young, which reached the settlement without admitting or denying the SEC's allegations, will pay $10.8 million in disgorgement and pre-judgment interest and a penalty of $1 million.
