Monitoring of TVA Fiscal Year 2015 Financial Statement Audit

The Inspector General Act of 1978, as amended, requires federal inspectors general, including the Tennessee Valley Authority (TVA) OIG to review the work of nonfederal auditors to assure their work complies with Government Auditing Standards (GAS) as set forth by the Comptroller General of the United States. We reviewed the work of Ernst & Young LLP (EY) in relation to its audit of TVA's fiscal year 2015 financial statements and internal control over financial reporting. Our review, as differentiated from an audit in accordance with GAS, was not intended to enable us to express, and we do not express, an opinion on TVA's financial statements or the effectiveness of TVA's internal control over financial reporting. EY is responsible for the auditor's reports dated November 20, 2015, and the conclusions expressed in those reports. However, our review of EY's work disclosed no instances where they did not comply, in all material respects, with GAS.
