the years then ended in accordance with accounting principles generally accepted in the United States of America. We relied on the work of the independent accounting firm to provide audit coverage pertaining to bank and investment accounts, debt issuances and related debt covenants. Our audit procedures in those areas were generally limited, therefore, to obtaining a sufficient basis for that reliance. Our assessment of internal controls was based on MDTA’s procedures and controls in place at the time of our fieldwork. Our tests of transactions and other auditing procedures were generally focused on the transactions occurring during our audit period of March 5, 2020 to May 31, 2025, but may include transactions before or after this period as we considered necessary to achieve our audit objectives. To accomplish our audit objectives, our audit procedures included inquiries of appropriate personnel, inspections of documents and records, tests of transactions, and to the extent practicable, observations of MDTA’s operations. Generally, transactions were selected for testing based on auditor judgment, which primarily considers risk, the timing or dollar amount of the transaction, or the significance of the transaction to the area of operation reviewed.

We also performed various data extracts of pertinent information from the State’s Central Payroll Bureau (payroll data), as well as from the contractor administering the State’s Corporate Purchasing Card Program (credit card activity). The extracts are performed as part of ongoing internal processes established by the Office of Legislative Audits and were subject to various tests to determine data reliability. We determined that the data extracted from these sources were sufficiently reliable for the purposes the data were used during this audit. We also extracted data from MDTA’s general ledger and purchasing and disbursement systems for the purpose of testing purchases and disbursements and extracted data from MDTA’s tolling customer service contractor for the purpose of testing collection efforts for electronic tolls. We performed various tests of the relevant data and determined that the data was sufficiently reliable for the purposes the data was used during the audit. Finally, we performed other auditing procedures that we considered necessary to achieve our audit objectives. The
