Quality Control Review on a Single Audit of the City of Phoenix, Arizona
This report presents the results of our self-initiated quality control review on Grant Thornton LLP’s single audit of the City of Phoenix’s (City) use of DOT grants during the City’s fiscal year ended June 30, 2014. During this period, the City expended approximately $184 million from DOT grant programs. Grant Thornton determined that the major DOT programs were the Federal Transit Cluster, the Airport Improvement Program, and the Highway Planning and Construction Cluster. We limited the scope of our QCR to the Federal Transit Cluster and the Airport Improvement Program because no Highway Planning and Construction Cluster funds were awarded directly to the City. We assigned overall rating of pass with deficiencies to Grant Thornton’s work. Therefore, Grant Thornton generally met the requirements of the Single Audit Act, OMB Circular A-133, and DOT’s major programs. We found nothing to indicate that Grant Thornton’s opinion on each of DOT’s major programs was inappropriate or unreliable.
