8. McKnight Handcraft is a manufacturer of picture frames for large retailers. Every picture frame passes through two departments: the assembly department and the finishing department. This problem focuses on the assembly department. The process-costing system at McKnight has a single direct-cost category (direct materials) and a single indirect-cost category (conversion costs). Direct materials are added when the assembly department process is 10% complete. Conversion costs are added evenly during the assembly department's process McKnight uses the weighted-average method of process costing. Consider the following data for the assembly department in April 2014: Physical Unit (Frames) Conversion Direct Materials Costs WIP, April 1 Started during April 2014 Completed during April 2014 WIP, April 30 Total Costs added during April 2014 $1,530 $156 60 510 450 120 $17,850 $11,544 Degree of completion: direct materials, 100%; conversion costs, 40% Degree of completion: direct materials, 100%; conversion costs, 15% a Required: Summarize the total assembly department costs for April 2014, and assign them to units completed (and transferred out) and to units in ending work in process. 9.
