The company uses process costing and has provided the following information for F5.300 production in January and February: The units remaining in work in process at the end of January were approximately 60 percent complete with respect to their conversion costs. During the month of February, all of the beginning work in process units were completed and the units remaining in work in process at the end of the month were approximately 80 percent complete with respect to their conversion costs.
