James Jones is employed in the accounting department of Smith Company. He was sent to Los Angeles on a business trip and had total expenses of $400. Because the trip extended over Saturday, he decided to "pad" his expense account by an extra $150. He felt this was OK since weekends are his own personal time. What would you recommend to James? Is this a legitimate business expense for Smith Company? What controls could Smith Company use to reduce the risk of this type of fraud?
