The ISBI’s compliance examination covering the two years ended June 30, 2025, will be issued at a later date. SYNOPSIS • (25-01) ISBI did not have adequate controls in place to track and record receivables and payables related to investment activity during the period. FINDINGS, CONCLUSIONS, AND RECOMMENDATIONS UNRECONCILED DIFFERENCES INCLUDED IN PENDING INVESTMENT ACTIVITY The Illinois State Board of Investment (ISBI) did not have adequate controls in place to track and record receivables and payables related to investment activity during the period. During the audit of the financial statements for the year ended June 30, 2025, we noted that ISBI’s payables for investments purchased and receivables for investments sold, did not reconcile with the amounts reported by the asset custodian. ISBI’s reported balances included other payables and other receivables which represented internal money movements between investment funds/ managers, which are internal balances and should be eliminated for financial reporting purposes. The impact of the unreconciled differences resulted in an uncorrected misstatement in the financial statements of $99,072,159, including $98,910,967 impacting the ISBI Member System and $161,192 impacting the Illinois Power Agency Trust Fund as follows: • Overstatement of payables for investments purchased • Understatement of net increase in fair value of investments/net position In addition to the uncorrected misstatement noted above, on the recommendation of its auditors, ISBI did reclassify a trial balance account for a balance that was classified as a receivable for investments sold to a payable for investments purchased. The reclassification reduced both amounts by $27,712,272. This reclassification had no impact on net position. (Finding 1, pages 28-29) We recommended ISBI establish internal controls to ensure that all investment- related balances are properly reconciled to the records of the asset custodian and are properly recorded within the financial statements. ISBI partially accepted our recommendations. ISBI stated that it agreed the variance described in the finding was accurate but disagreed with the characterization that the variance was the result of improper controls. AUDITOR’S OPINIONS The auditors stated the financial statements of ISBI as of and for the year ended June 30, 2025, are fairly stated in all material respects. This financial audit was conducted by RSM US LLP. COURTNEY DZIERWA Division Director This report is transmitted in accordance with Section 3-14 of the Illinois State Auditing Act. FRANK J.
