A digest covering ISBI’s financial audit as of and for the year ended June 30, 2023, was previously released on January 18, 2024. This report contains four findings. The financial audit report contained no findings. SYNOPSIS • (23-2) The Illinois State Board of Investment had not implemented adequate internal controls over documenting the reviews of its service providers. FINDINGS, CONCLUSIONS, AND RECOMMENDATIONS LACK OF ADEQUATE CONTROLS OVER THE REVIEW OF INTERNAL CONTROLS FOR SERVICE PROVIDERS The Illinois State Board of Investment (ISBI) had not implemented adequate internal controls over documenting the reviews of its service providers. During our examination, we noted that ISBI did not maintain documentation of its independent internal control review of the System and Organization Control (SOC) reports for four of four (100%) service providers. (Finding 2, page 9) We recommended ISBI implement controls to conduct formal reviews of the SOC reports of its service providers and to ensure these reviews are formally documented. Further, we recommended the reviews document deviations noted in the service providers’ SOC reports to determine the impact to ISBI’s internal control environment, and we recommended these reviews should include the subservice providers to determine their impact to ISBI’s internal controls, and the Complementary User Entity Controls (CUECs) as they relate to ISBI’s internal controls. ISBI agreed with our recommendations. OTHER FINDINGS The remaining findings pertain to failure to implement controls related to cybersecurity programs and practices, inadequate computer security controls, and insufficient controls over monthly reconciliations. We will review ISBI’s progress towards the implementation of our recommendations in our next State compliance examination. AUDITOR’S OPINION The financial audit report was previously released.
