Springtime Paints makes quality paint in one production department. Production begins with the blending of various chemicals, which are added at the beginning of the process, and ends with the canning of the paint. Canning occurs when the mixture reaches the 90 percent stage of completion. The gallon cans are then transferred to the Shipping Department for crating and shipment. Labor and overhead are added continuously throughout the process. Factory overhead is applied at the rate of $3 per direct labor hour.

Prior to May, when a change in the process was implemented, work in process inventories were insignificant. The change in process enables more production but results in large amounts of work in process. The company has always used the weighted average method to determine equivalent production and unit costs. Now production management is considering changing from the weighted average method to the first-in, first-out method.
