Project ID
File Attachment

On November 4, 2011, we issued our quality control report of Clifton Gunderson LLP's report attestation engagement pertaining to the Enterprise Services Center's (ESC) description of its system and the suitability of the controls' design and operating effectiveness.  Clifton Gunderson found that in all material respects, for the period of October 1, 2010 to June 30, 2011: 1) ESC's description of its controls fairly presents ESC's system that was designed and implemented throughout that period; 2) the controls were suitably designed to provide reasonable assurance that the controls' objectives would be achieved if the controls operated effectively throughout that period and user entities applied the complementary user controls contemplated in the design of ESC's controls throughout that period; and 3) the controls tested, which together with the complementary user entities' controls, if operating effectively, were those necessary to provide reasonable assurance that the control objectives were achieved, operated effectively throughout that period.  Our quality control review disclosed no instances in which Clifton Gunderson did not comply, in all material respects, with generally accepted government auditing standards.
