Patel and Sons Inc. uses a standard cost system to apply factory overhead costs to units produced. Practical capacity for the plant is defined as 52,200 machine hours per year, which represents 26,100 units of output. Annual budgeted fixed factory overhead costs are $261,000 and the budgeted variable factory overhead cost rate is $2.70 per unit. Factory overhead costs are applied on the basis of standard machine hours allowed for units produced. Budgeted and actual output for the year was 19,700 units, which took 41,200 machine hours. Actual fixed factory overhead costs for the year amounted to $253,800 while the actual variable overhead cost per unit was $2.60. Based on the information provided above, provide an appropriate end-of-year closing entry for each of the following two independent situations: (a) the net factory overhead cost variance is closed entirely to Cost of Goods Sold (CSG), and (b) the net factory overhead variance is allocated among WIP Inventory, Finished Goods Inventory, and CGS using the following percentages: 30%, 20%, and 50%, respectively.
