Securing TRA business assets

The role of internal audit is to provide independent assurance that an organization’s risk management, governance and internal control processes are operating effectively.


The internal audit function was authorized by the TRA Board of Trustees. As a result, a charter was approved governing internal audit practices and the TRA Audit Committee.

Leslie Nagel was hired in 2009 as the TRA Internal Auditor. She is a Certified Public Accountant, a Certified Internal Auditor, and a Certified Employee Benefits Specialist as awarded by the International Foundation of Employee Benefit Plans. Before joining TRA, she was an audit manager for LarsonAllen (now CliftonLarsonAllen), a public accounting firm. She is a board member of the Association of Public Pension Fund Auditors. Leslie received a Bachelor of Arts degree in Business Administration—Accounting from Concordia College in Moorhead.
