Question

Weighted-average method. Porter 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 Porter 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.

Porter uses the weighted-average method of process costing. Consider the following data for the Assembly Department in April 2009:

Summarize total Assembly Department costs for April 2009, and assign total costs to units completed (and transferred out) and to units in ending work in process.

Answer 1

Weighted-average method.

 

Solution Exhibit 17-35A shows equivalent units of work done to date of:

 

Direct materials                       625 equivalent units

Conversion costs                     525 equivalent units

 

That direct materials are added when the Assembly Department process is 10% complete. Both the beginning and ending work in process are more than 10% complete and hence are 100% complete with respect to direct materials. 

 

Solution Exhibit 17-35B summarizes the total Assembly Department costs for April 2009, calculates cost per equivalent unit of work done to date for direct materials and conversion costs, and assigns these costs to units completed (and transferred out), and to units in ending work in process using the weighted-average method.
