The Principles Corporation is a manufacturer of centrifuges. Fixed and variable manufacturing overheads are allocated to each centrifuge using budgeted assembly-hours. Budgeted assembly time is 2 hours per unit. The following table shows the budgeted amounts and actual results related to overhead for June 2017. Actual Static The Principles Corporation (June 2017) Results Budget Number of centrifuges assembled and sold 230 170 Hours of assembly time 391 Variable manufacturing overhead cost per hour of assembly time $ 30.00 Variable manufacturing overhead costs $ 12,142 Fixed manufacturing overhead costs $ 18,060 $ 16,660 Requirement 1. Prepare an analysis of all variable manufacturing overhead and fixed manufacturing overhead variances. Begin by calculating the following amounts for the variable overhead. Variable OH Actual Input Actual Costs x Flexible Allocated Incurred Budgeted Rate Budget Overhead $ 12,142 $ 11,730 $ 13,800 $ 13,800 Now complete the table below for the fixed manufacturing overhead. Fixed OH Same Budgeted Actual Costs Incurred Lump Sum Regardless of Output Level Flexible Budget Allocated Overhead 18,060 $ 16,660 $ 16,660 $ 22,540 Now complete the 4-variance analysis using the amounts you calculated above. (If no variance exists leave the dollar value blank. Label the variance as favorable (F), unfavorable (U) or never a variance (N).) 4-Variance Analysis Variable OH Spending Variance Efficiency Variance Production-Volume Variance
