Premium, Inc. uses a standard cost system and provides the following information. (Click the icon to view the information.) Premium allocates manufacturing overhead to production based on standard direct labor hours. Premium reported the following actual results for 2018: actual number of units produced, 1,000; actual variable overhead, $5,000; actual fixed overhead, $3,500; actual direct labor hours, 1,900. Read the requirements. Requirement 1. Compute the variable overhead cost and efficiency variances and fixed overhead cost and volume variances. Begin with the variable overhead cost and efficiency variances. Select the required formulas, compute the variable overhead cost and efficiency variances, and identify whether each variance is favorable (F) or unfavorable (U). (Abbreviations used: AC = actual cost; AQ = actual quantity; FOH = fixed overhead; SC = standard cost; SQ = standard quantity; VOH = variable overhead.) Formula Variance VOH cost variance VOH efficiency variance Data Table .X 1 $ 2,200 $ 3,300 Static budget variable overhead Static budget fixed overhead Static budget direct labor hours Static budget number of units 1,100 hours 550 units Standard direct labor hours 2 hours per unit Print Done Now compute the fixed overhead cost and volume variances. Select the required formulas, compute the fixed overhead cost and volume variances, and identify whether each variance is favorable (F) or unfavorable (U). (Abbreviations used: AC = actual cost; AQ = actual quantity; FOH = fixed overhead; SC = standard cost; SQ = standard quantity.) Formula Variance FOH cost variance = FOH volume variance Il Il Requirement 2. Explain why the variances are favorable or unfavorable. The variable overhead cost variance is because the actual cost per direct labor hour was than the standard cost per direct labor hour. The variable overhead efficiency variance is because management used direct labor hours than standard and variable overhead is applied (incurred) based on direct labor. The fixed overhead volume variance is because total fixed overhead cost allocated to units was than the total budgeted fixed overhead cost
