Kathy Lentz, Rob Snyder, and Tom Rohm were all general partners in a consulting business. Each partner owned one-third of the business. The partnership agreement stated that all three partners must approve vouchers for payments in amounts exceeding $5,000. While Tom was on vacation, Kathy and Rob decided to purchase a new computer system costing $6,800. A voucher was prepared and Rob signed both his and Tom's name. Kathy signed her name and gave the voucher to the accounts payable clerk, who wrote the check for $6,800.
