Quality Control Review of Single Audit on the Michigan Department of Transportation
On September 29, 2011, we issued a quality control report on a single audit performed by the Auditor General of the State of Michigan, on the Michigan Department of Transportation's (Michigan DOT) use of U.S. Department of Transportation (DOT) grants for the fiscal year ending September 30, 2010. During this period, Michigan DOT expended approximately $2.7 billion from DOT grant programs. The major DOT programs tested by the Auditor General included the 1) Highway Planning and Construction Program, 2) the Federal Transit Cluster, 3) the Federal Transit Services Cluster, 4) the Formula Grants for Other Than Urbanized Areas, and 5) the Airport Improvement Program. We determined the work of the Auditor General to be acceptable, and therefore met the requirements of generally accepted government auditing standards, the Single Audit Act, and OMB Circular A-133. We found nothing to indicate that the Auditor General's opinion on Michigan DOT's financial statements or reports on Michigan DOT's internal controls and compliance were inappropriate or unreliable.
