Allen imports furniture from China. He travels to his suppliers’ businesses three times a year to inspect how the furniture is made, the conditions at the factory, and how much workers are paid. When he is satisfied that the supplier meets his standards for humanitarian treatment of workers and ethical work practices, he places an order for furniture to be made by the company. The suppliers usually require part of the payment upfront or proof that payment will be made on delivery. Because Allen has been in business for many years, and has used the same bank for his business for the entire time he has been in business, he works out an agreement with his banker that the bank will advance him funds for a short-term at prime interest rate plus two percent. What kind of transaction did Allen enter into with the bank?
