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 $ 65 95 $160 *Based on capacity of 301,500 direct-labor hours per month. The following information is available for the month of October. Variable overhead costs were $3,900,000. Fixed overhead costs were $6,075,000. 57,300 switches were produced, although 60,300 switches were scheduled to be produced. 278,000 direct-labor hours were worked at a total cost of $4,125,000. 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).)
