Becton Labs Inc. produces various chemical compounds for industrial use. One compound, called Fludex, is prepared by means of an elaborate distilling process. The company has developed standard costs for one unit of Fludex, as follows: Direct materials Direct labour Variable overhead 2.60 mL at 1.60 hours at 1.60 hours at $ $19 per millilitre $ 23.00 per hour $ 9.00 per hour During November, the following activity was recorded by the company relative to production of Fludex: a. Materials were purchased, 12,000 millilitres at a cost of $261,000. b. There was no beginning inventory of materials on hand to start the month; at the end of the month, 2,500 millilitres of material remained in the warehouse unused. c. The company employs 35 lab technicians to work on the production of Fludex. During November, each worked an average of 161 hours at an average rate of $14 per hour. d. Variable manufacturing overhead is assigned to Fludex on the basis of direct labour-hours. Variable manufacturing overhead costs during November totalled $18,100. e. Fixed overhead is also allocated on the basis of direct labour-hours. The company had budgeted $12,768 for the month but underapplied it by $613. f. During November, 3,740 good units of Fludex were produced. The normal volume for the month is 3,990 good units. The company's management is anxious to determine the efficiency of the activities surrounding the production of Fludex. The company's policy is to investigate any variance more than 2% different from the relevant standard. Required: 4. Compute the fixed overhead cost variances for November. (Indicate the effect of each variance by selecting "F" for favourable, "U" for unfavourable, and "None" for no effect (i.e., zero variance).)
