Travel & Entertainment – 2014 Audit Summary
AGA-EEI Internal Audit - Power Of Visual And Interactive Analysis
1. T&E is a mandatory annual audit to address high inherent fraud and reputational risk
2. By applying our employee model to T&E data during the 2014 Audit, we provided risk
assurance over XXXK transactions, and noted only XX transactions with an immaterial
impact (<0.5% of total value) that may require analysis by the business
3. In 2015, similar IA assurance will be provided using 80% fewer resources
4. Accounts Payable began using the tool on a monthly basis to provide monitoring and
oversight of T&E expenses to determine if company-wide or targeted messaging is needed to
change employee behavior
