Finding Number: 2025-002 Finding Title: Cash Collateralization (Repeat Finding 2024-004) Planned Corrective Action: Management acknowledges the finding regarding cash collateralization. As of September 30, 2025, the Coalition's cash deposits were pledged and collateralized. After year-end, management became aware that two affiliated financial institutions participating in the deposit sweep program had inadvertently assigned the same certificate numbers during the nightly sweep process. Consequently, a portion of the Coalition's deposits may have been swept into the same financial institution, resulting in balances that may have temporarily exceeded applicable FDIC insurance limits. Although this condition resulted from the financial institutions' sweep process rather than the Coalition's cash management practices, management recognizes its responsibility to monitor deposit coverage and ensure compliance. To address this finding, the Coalition will implement the following corrective actions: 1. Meet with representatives from both participating banks to discuss the issue and formally notify them of the audit finding. 2. Request written confirmation that the nightly sweep process has been reviewed and modified to prevent deposits from being placed with the same institution through duplicate certificate assignments or other system errors. This may happen from time-to-time but IntraFi corrects those deposits and reallocates them, It will be reviewed weekly to make sure they did reallocate those funds. 3. Communication with certain representatives within the financial institution will be contacted by NUHIC and will need to request that dollars are required to be transferred to IntraFi to remain in compliance of your audit before 2:30pm everyday. 4. Obtain and review periodic reports from the financial institutions identifying the banks holding swept deposits and the amount of funds placed with each institution. 5. Establish a weekly review process to monitor cash balances, FDIC insurance coverage, and collateralization to identify any exceptions on a timely basis. 6. Maintain documentation of all reviews, bank communications, and corrective actions as part of the Coalition's internal control procedures. 7. If the financial institutions cannot provide adequate assurance that deposits will remain fully insured or properly collateralized, the Coalition will evaluate alternative cash management options, including other insured cash sweep providers or collateralized deposit arrangements. Management believes these corrective actions will strengthen oversight of the Coalition's cash management process and reduce the risk of future noncompliance with FDIC insurance requirements.
