To: EisnerAmper LLP Date: October 29, 2026 Subject: Response to Management Letter Commend for the Fiscal Year Ended 6/30/2025 Thank you for your management letter dated 10/12/2026 and for your valuable insights and recommendations regarding our financial processes and controls. Areas of improvement identified by the audit team are acknowledged. CUCS is committed to addressing the points raised. For each recommendation we have taken corrective actions as outlined below. Response to comment#1: CUCS experienced delays in producing final audit schedules due to staffing transitions, including the unanticipated resignation of the Chief Financial Officer (CFO) and other key executive members. While various members of the fiscal team are responsible for preparing audit schedules, the CFO has historically overseen the initiation and finalization of the financial statements and served as the primary liaison with EisnerAmper during the audit process. We appreciate the opportunity to respond to the internal control deficiencies identified during your audit for fiscal year 2025. We acknowledge your finding that our current internal control processes may not consistently detect and correct material misstatements in a timely manner. This concern has been noted and taken seriously by management. Corrective Actions: Staffing and Leadership Stabilization • A Part-time Chief Financial Officer Consultant has been hired to provide leadership, oversight, and stability within the Finance Department while CUCS continues to recruit for a permanent CFO. • Internal resources are being strengthened to reduce reliance on external accounting services. Process and Calendar Improvements • An annual financial reporting and audit preparation calendar has been developed and implemented to improve planning and accountability for deliverables. • Key deadlines for closing entries, reconciliations are now documented and monitored quarterly. • Enhance our review procedures by implementing an additional layer of financial oversight. All required financial reports and key reconciliation’s will be conducted monthly. Capacity Building and Training • Cross-training of finance staff is underway to reduce dependency on single individuals and improve team resilience. Monitoring and Follow-Up • Regular updates to the Executive Team and Audit Committee. Response to comment#2: We acknowledge the auditor’s observation regarding the presence of former employees remaining listed as authorized signers on CUCS bank accounts. We agree that maintaining accurate and up-to-date signer authorizations is critical to safeguarding the organization’s financial assets. In response to this finding, CUCS has taken the following corrective actions: Immediate Review and Removal of Former Employees All bank accounts have been reviewed, and individuals who are no longer employed by CUCS have been removed from signer authority. This process was completed promptly upon identification of the issue. Ongoing Monitoring and Annual Review We are instituting an annual review of all authorized bank signers to ensure that records are current and appropriately reflect active personnel with approval authority. This review will be documented and conducted under the direction of the new part-time CFO consultant. CUCS is committed to maintaining effective internal controls over its financial operations, and we appreciate the auditor’s recommendation in helping us strengthen this process.
