Treasury OIG should follow-up with Oklahoma's management to confirm if the $35,499,181 noted as unsupported expenditures within the Grants greater than or equal to $50,000, Transfers greater than or equal to $50,000, Direct Payments greater than or equal to $50,000, Aggregate Reporting less than $50,000, and Aggregate Payments to Individuals payment types can be supported. If support is not provided, Treasury OIG should recoup the funds or request Oklahoma management to provide support for replacement expenses, not previously charged to CRF, that were incurred during the period of performance. In addition, Treasury OIG should request Oklahoma management to provide support for replacement expenses, not previously charged, that were eligible during the CRF period of performance for the $75,926 of ineligible costs charged to the Transfers greater than or equal to $50,000 and Direct Payments greater than or equal to $50,000 payment types. If support is not provided, Treasury OIG should recoup the funds. Based on Oklahoma's responsiveness to Treasury OIG's requests and its ability to provide sufficient documentation and/or replace unsupported and ineligible transactions charged to CRF with valid expenditures, Treasury OIG should determine the feasibility of conducting an audit for the Grants greater than or equal to $50,000, Transfers greater than or equal to $50,000, Direct Payments greater than or equal to $50,000, Aggregate Reporting less than $50,000, and Aggregate Payments to Individuals payment types. Treasury OIG should follow-up with Treasury's Office of Capital Access to ensure that management decision letters are issued on the findings identified by the auditor in the Single Audit report. Treasury OIG should obtain and review Oklahoma's FY 2022 Single Audit report, as this was not available to Castro during our desk review planning procedures. Treasury OIG should follow-up with Oklahoma and request management to perform an analysis over all grants-reporting portal balances to determine if there were other instances, separate from those identified by Castro, of subscription costs that extended past the expenditure deadline of September 30, 2022.
