Exercise 11-32 Overhead Variances (LO 11-5) Montoursville Control Company, which manufactures electrical switches, uses a standard-costing system. The standard production overhead costs per switch are based on direct-labor hours and are as follows: Variable overhead (5 direct-labor hours @ $13.00 per hour) Fixed overhead (5 direct-labor hours @ $19.00 per hour)* Total overhead *Based on capacity of 300,500 direct-labor hours per month. $ 65 95 $ 160 The following information is available for the month of October. Variable overhead costs were $3,660,000. Fixed overhead costs were $5,775,000. 57,100 switches were produced, although 60,100 switches were scheduled to be produced. 276,000 direct-labor hours were worked at a total cost of $3,925,000. Required: Compute the variable-overhead spending and efficiency variances and the fixed-overhead budget and volume variances for October. (Indicate the effect of each variance by selecting "Favorable" or "Unfavorable". Select "None" and enter "O" for no effect (i.e., zero variance).)
