Auditors who adhere to the professional auditing standards are viewed as conducting a quality audit. A lack of adherence to the professional auditing standards heightens the risk that the auditor will provide an unqualified audit opinion on financial statements that are materially misstated. This lesson is highlighted in the 20042006 audits of Thornton Precision Components, Limited (TPC) performed by Ernst & Young, LLP UK (E&Y UK). TPC became a wholly owned U.K. subsidiary of Symmetry Medical, Inc. in 2003. Symmetry became a public company in 2004 and was listed on a U.S. stock exchange. Its consolidated financial statements included TPCs financial data. Beginning in 2003, Ernst & Young, LLP (E&Y US) became Symmetrys audit firm. In connection with the 20042006 audits of Symmetry, E&Y US engaged E&Y UK to perform audits of TPC, using PCAOB auditing standards. During the 20042006 audits, E&Y US relied on E&Y UKs audits to issue unqualified audit opinions for Symmetry. From 1999 through September 2007, TPCs management participated in multiple schemes to increase TPCs revenues, net income, and other performance indicators. These schemes included booking fictitious revenues, understating costs of goods sold, creating fictitious inventories, and improperly capitalizing certain expenses. The fraud at TPC was not discovered by the auditors but only came to light in 2007 when a TPC employee alerted Symmetrys CEO to the fraud. In 2008, Symmetry restated its financial statements, which included, among other items, significant reductions in Symmetrys net income. In 2012, the SEC concluded that E&Y UK (a firm registered with the PCAOB) had conducted its audits in such a way that the audits did not adhere to the relevant professional auditing standards. Deficiencies in E&Y UKs 20042006 audits of TPC included a failure to perform appropriate procedures to audit the accounts receivable balances; adequately review top-side journal entries; properly audit inventory; and a failure to plan, staff, and supervise the audits. During the audit, the audit partner and manager did not appropriately question managements representations, did not fully document the results of testing, did not appropriately consider the risks of misstatements due to fraud, and did not exercise due professional care and professional skepticism. The SEC prohibited both the audit manager and partner of TPC from auditing U.S. public companies for two years.
