The Department of the Air Force requested a Statements on Standards for Attestation Engagements No. 18 (SSAE 18) examination of the Defense Enterprise Accounting and Management System (DEAMS) as of June 30, 2023. We contracted with the independent public accounting firm of Ernst & Young LLP (EY) to perform the SSAE 18 examination of DEAMS. The objective of EY’s attestation examination is to issue an opinion on the Department of the Air Force’s description of DEAMS and the suitability of the design of controls to achieve the related control objectives as of June 30, 2023. The objective of our oversight project is to provide contract oversight of EY’s attestation examination and determine whether EY complied with applicable attestation and generally accepted government auditing standards.
