OIG-CA-25-016 - Recommendation 4-1

Treasury OIG determine the feasibility of performing additional follow-up with Arizona to determine if there were other instances of unsupported balances within the remaining untested balance of Substantially Dedicated Payroll costs. Castro further recommends that Treasury OIG follow-up with Arizona's management to confirm if the $18,133,411 noted as unsupported expenditures within the Aggregate Payments to Individuals payment type can be supported. If support is not provided, Treasury OIG should recoup the funds or request Arizona's management to provide support for replacement expenses, not previously charged, that were eligible during the CRF period of performance. Further, based on Arizona management's responsiveness to Treasury OIG's requests and management's ability to provide sufficient documentation and/or replace unsupported transactions charged to CRF with valid expenditures, Castro recommends Treasury OIG determine the feasibility of conducting an audit for the Aggregate Payments to Individuals payment type.
