Weighted-average method, spoilage, equivalent units. (CMA, adapted) Consider the following data for November 2017 from MacLean Manufacturing Company, which makes silk pennants and uses a process-costing system. All direct materials are added at the beginning of the process and conversion costs are added evenly during the process. Spoilage is detected upon inspection at the completion of the process. Spoiled units are disposed of at zero net disposal value MacLean Manufacturing Company uses the weighted-average method of process costing

Compute equivalent units for direct materials and conversion costs.

Equivalent Units: Materials =  10630  

Equivalent Units :   Conversion  =    9525

The weighted average method equivalent unit production implies that the units completed and the ending inventory completed plus any spoilage normal or abnormal is taken is accounted for.

The weighted average method EUP can also be determined by adding the beginning units and units started

The normal and abnormal spoilage are taken 100 % because all the spoilage is evident once the goods are completed.
