Treasury OIG should confirm if the transactions noted as unsupported expenditures within Aggregate Reporting less than $50,000 can be supported. If support is not provided, Treasury OIG should recoup the funds or request that Bergen County management provide support for replacement expenses, not previously charged, that were eligible during the CRF period of performance. Further, based on Bergen County's responsiveness to Treasury OIG's requests and its ability to provide sufficient documentation and/or replace unsupported transactions charged to the CRF with valid expenditures, we recommend Treasury OIG determine the feasibility of conducting an audit for the Aggregate Reporting less than $50,000 payment type.
