Alden Company uses a three-variance analysis for factory overhead variances. Practical capacity is defined as 28 setups and 28,000 machine hours to manufacture 5,600 units for the year. Selected data for 2019 follow: Budgeted fixed factory overhead: Setup cost Other Total factory overhead cost incurred Variable factory overhead rate: Per setup Per machine hour Total standard machine hours allowed for the units manufactured Machine hours actually worked Actual total number of setups Actual number of units produced during the year Standard number of setups for units produced during the year $ 95,200 150,000 $245,200 $498,000 $ 450 $ 8.00 23,000 hours 26,000 hours 24 4,600 23 Required: 1. Compute: (a) the total overhead spending varlance, (b) the overhead efficiency varlance, and (c) the total overhead flexible-budget varlance for 2019. Label each variance as favorable (F) or unfavorable (U). 2. Assume that the company Includes all setup costs as variable factory overhead. The budgeted total fixed overhead, therefore, is $150,000, and the standard variable overhead rate per setup is $3,850. What Is: (a) the total overhead spending variance. (b) the overhead efficiency varlance, and (c) the total overhead flexible-budget variance for the year? Label each variance as favorable (F) or unfavorable (U). 3. Assume that the company uses only machine hours as the activity measure to apply both variable and fixed overhead, and that it Includes all setup costs as variable factory overhead. What is (a) the Total Overhead Spending Varlance, (b) the Overhead Efficiency Variance, and (c) total Overhead Flexible-Budget Variance for the year? Indicate whether each variance is favorable (F) or unfavorable (U).
