FINDINGS, CONCLUSIONS, AND RECOMMENDATIONS INADEQUATE INTERNAL CONTROLS RELATED TO REVIEW OF FINANCIAL STATEMENTS The Office of the Treasurer (Office) had inadequate internal controls over the College Savings Program financial statement preparation and review process. During preparation of the financial statements, the Office did not verify completeness of the reports obtained from the service provider that were used to report the cash and cash equivalents, fixed income assets, or the mutual funds balances in the financial statements. This led to the following variances in the Statement of Net Position and in the Note 2 disclosure: • Cash and Cash Equivalents were understated by $98,872,583. • Fixed Income Assets were understated by $294,402,432. • Mutual Fund Assets were overstated by $110,633,350. The Office obtained updated financial information while addressing the variances noted above. The following variances remained after the financial statements were first updated: • Cash and Cash Equivalents were overstated by $148,894,384. • Fixed Income Assets were understated by $241,541,251. • Mutual Fund Assets were overstated by $110,633,350. The Office ultimately corrected the financial statements for all material errors described above. (Finding 1, pages 164-165) We recommended the Office improve controls over the financial statement preparation and review process by verifying completeness from the service providers used to report asset balances in the financial statements. The Office accepted the recommendation and stated it will examine the review and documentation procedures of Program Manager support used in preparation of the financial statements for improvement.
