Manny Fold owns a factory that specializes in making titanium valves for high performance engines on a just in time basis. Thus, Manny produces what he sells in a particular month. There are no inventories of finished goods or work in process. However, Manny does require that an inventory of direct raw materials equal to 10% of next month’s production requirement be available at the end of each month. To build his business and gain new customers Manny has extended generous credit terms to his customers. While Manny is confident about the fundamentals of his business, he is concerned about the possible cash flow implications.
