Question

Becton Labs, Inc., produces various chemical compounds for industrial use. One compound, called Fludex, is prepared using an elaborate distilling process. The company has developed standard costs for one unit of Fludex, as follows:

	Standard Quantity or Hours		Standard Price or Rate			Standard Cost
Direct materials	2.60	ounces	$	20.00	per ounce	$	52.00
Direct labor	0.60	hours	$	16.00	per hour		9.60
Variable manufacturing overhead	0.60	hours	$	4.50	per hour		2.70
Total standard cost per unit						$	64.30

During November, the following activity was recorded related to the production of Fludex:

1. Materials purchased, 13,000 ounces at a cost of $244,400.

2. There was no beginning inventory of materials; however, at the end of the month, 3,300 ounces of material remained in ending inventory.

3. The company employs 20 lab technicians to work on the production of Fludex. During November, they each worked an average of 150 hours at an average pay rate of $14.00 per hour.

4. Variable manufacturing overhead is assigned to Fludex on the basis of direct labor-hours. Variable manufacturing overhead costs during November totaled $6,500.

5. During November, the company produced 3,600 units of Fludex.

Required:

1. For direct materials:

a. Compute the price and quantity variances.

b. The materials were purchased from a new supplier who is anxious to enter into a long-term purchase contract. Would you recommend that the company sign the contract?

2. For direct labor:

a. Compute the rate and efficiency variances.

b. In the past, the 20 technicians employed in the production of Fludex consisted of 4 senior technicians and 16 assistants. During November, the company experimented with fewer senior technicians and more assistants in order to reduce labor costs. Would you recommend that the new labor mix be continued?

3. Compute the variable overhead rate and efficiency variances.

Answer 1

Req-1(A)Computation of Material Price & Quanntity Variance

Material price variance = (SP - AP) * AQ purchased ' = ($20- $18.80) * 13000 = $15600 F

Material quantity variance = (SQ - AQ Used ) * SP ' = (9360 Ounce -9700 Ounce ) * $20 = $6800U

Refrence

Standard qty of material = 3600 Units *2.60 Ounces= 9360 ounce

Actual quantity of material purchased = 13000 ounce

Actual quantity of material used = 13000 - 3300 = 9700 ounce

Standard price of material = $20 per ounce

Actual price of material = $244400 / 13000 = $18.80

Req-1(B),Yes , Company should signed a contracct because , Material Price variance shows favourable which shows that actul material proceurement price is lesser than Standard Price. Yes Company should sign the contract

Req-2(a) Labour Rate & Efficiency Variance

Direct labor rate variance = (SR - AR) * AH = ($16 - $14) *3000 Hour = $6000 F

Direct labor efficiency variance = (SH - AH) * SR = (2160- 3000) * $16= $13440 U

Refrence

Standard hours of direct labor = 3600 Unit *0.60 Hour = 2160hours

Standard rate of direct labor = $16 per hour

Actual hours of direct labor = 20 Technician *150 Hour = 3000 hours

Actual rate of direct labor = $14 per hour

Req:2(b)NO, New labor mix should not be continued because Employing more assistant rather senior technician resulted in favorable direct labor rate variance but unfavorable laor efficiency variance. Further unfavorable efficiency variance is higher than favorable rate variance,

Req-3 Variable OH Rate & Efficiency Variance

Variable overhead rate variance = (SR - AR) * AH = (4.5 - $2.167) *3000 = $7000 F

Variable overhead efficiency variance = (SH - AH) * SR = (2160 - 3000) * $4.5 = $3780 U

Refrence

Standard hours of direct labor = 3600 Unit *0.60 Hour = 2160hours

Standard rate of variable overhead= $4.5 per hour

Actual hours of direct labor = 20 Technician *150 Hour = 3000 hours

Actual rate of variable overhead = $6500 / 3000 = $2.167
