ACCT7107 Lecture 7 Tutorial Questions 8-34 Flexible-budget variances, review of Chapters 7 and 8. Michael Roberts is a cost accountant and business analyst for Darby Design Company (DDC), which manufactures expensive brass doorknobs. DDC uses two direct cost categories: direct materials and direct manufacturing labor. Roberts feels that manufacturing overhead is most closely related to material usage. Therefore, DDC allocates manufacturing overhead to production based upon pounds of materials used. At the beginning of 2017, DDC budgeted annual production of 410,000 doorknobs and adopted the following standards for each doorknob: Input Cost/Doorknob Direct materials (brass) 0.3 lb. @\$9/lb. \$ 2.70 Direct manufacturing labor 1.2 hours @\$16/hour 19.20 Manufacturing overhead: Variable \$4/lb. 0.3 lb. 1.20 Fixed \$14/lb. 0.3 lb. 4.20 Standard cost per doorknob \$27.30 Actual results for April 2017 were as follows: Production 32,000 doorknobs Direct materials purchased 12,900 lb. at \$10/lb. Direct materials used 9,000 lbs. Direct manufacturing labor 29,600 hours for \$621,600 Variable manufacturing overhead \$ 64,900 Fixed manufacturing overhead \$160,000 Required: 1. For the month of April, compute the following variances, indicating whether each is favorable (F) or unfavorable (U): a. Direct materials price variance (based on purchases) b. Direct materials efficiency variance c. Direct manufacturing labor price variance d. Direct manufacturing labor efficiency variance e. Variable manufacturing overhead spending variance f. Variable manufacturing overhead efficiency variance g. Production-volume variance h. Fixed manufacturing overhead spending variance 2. Can Roberts use any of the variances to help explain any of the other variances? Give examples.
