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

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
