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. Leslie is a Certified Public Accountant (CPA), Certified Internal Auditor (CIA), and a Certified Employee Benefits Specialist (CEBS), as awarded by the International Foundation of Employee Benefit Plans. Before joining TRA, she was an Audit Manager for LarsonAllen, a regional public accounting firm.
