Required Do Exercise4.20 using the FIFO method of process costing. Explain any difference between the cost of work completed and transferred out and cost of closing work in progress in the Assembly Department under the weighted-average method and the FIFO method.

Exercise4.20

Euro-Défense is a manufacturer of military equipment. Its Tourcoing plant manufactures the Déca-Pite missile under contract to the French government and friendly countries. All Déca-Pites go through an identical manufacturing process. Every effort is made to ensure that all Déca-Pites are identical and meet many demanding performance specifications. The product-costing system at the Tourcoing plant has a single direct-cost category (direct materials) and a single indirect-cost category (conversion costs). Each Déca-Pite passes through two departments – the Assembly Department and the Testing Department. Direct materials are added at the opening of the process in Assembly. Conversion costs are added evenly throughout the two departments. When the Assembly Department finishes work on each Déca-Pite, it is immediately transferred to Testing.
Euro-Défense uses the weighted-average method of process costing. Data for the Assembly Department for October 2022 are:

Required 1 For each cost element, calculate equivalent units of work done in October 2022 in the Assembly Department. Show physical units in the first column.
2 For each cost element, calculate cost per equivalent unit of opening work in progress and of work done in October 2022.
3 Summarise the total Assembly Department costs for October 2022 and assign these costs to units completed (and transferred out) and to units in closing work in progress using the weighted-
average method.
4 Prepare a set of summarised journal entries for all October 2022 transactions affecting Work in Progress – Assembly. Set up a T-account for Work in Progress – Assembly and post the entries to it.
