In Class #7.1 Direct materials and manufacturing labour variances, solving unknowns All given items are designated by an asterisk. Flexible Budget Actual Costs (Budgeted Input Incurred Qty.

Flexible budget – Efficiency variance = \$40,000 – \$2,000 = \$38,000 Actual DMLH = \$38,000 ÷ Budgeted price of \$20/hour = 1,900 hours 3. \$38,000 + Price variance, \$1,900 = \$39,900, the actual direct manuf. labour cost Actual rate = Actual cost ÷ Actual hours = \$39,900 ÷ 1,900 hours = \$21/hour 4. Standard qty. of direct materials = 4,000 units × 3 kg/unit = 12,000 kg 5. Flexible budget + Dir. matls. effcy. var. = \$60,000 + \$2,500 = \$62,500 Actual quantity of dir. matls. used = \$62,500 ÷ Budgeted price per kg = \$62,500 ÷ \$5/lb = 12,500 kg 6. Actual cost of direct materials, \$68,250 – Price variance, \$3,250 = \$65,000 Actual qty. of direct materials purchased = \$65,000 ÷ Budgeted price, \$5/kg = 13,000 kg 7. Actual direct materials price = \$68,250 ÷ 13,000 kg = \$5.25 per kg In Class #7.2 Direct-materials variances, long-term agreement with supplier Required 1 Assume that Metalmoulder’s standard materials input per machining system is 198 kilograms of metal. Compute the direct materials price variance and direct materials efficiency variance for each month of the January to May 2013 period.

The unfavourable materials price variances in March and April imply that Metalmoulder paid more than \$144 per kilogram above the 2,400 kilogram contract amount. Contract Actual Price Amount for Cost for Quantity of per Kilogram Total Actual 2,400 kg: Purchases Purchases of Purchases Month Costs Incurred 2,400  \$144 Above 2,400 kg Above 2,400 kg Above 2,400 kg (1) (2) (3) (4) = (2) – (3) (5) (6) = (4) ÷ (5) March \$530,712 \$345,600 \$185,112 1,110 \$166.77 April 474,317 345,600 128,717 688 187.09 The percentage price increases for the additional purchases above 2,400 kilograms are: Actual Price Standard Price % Increase March \$166.77 \$144 15.8 April 187.09 144 29.9 With a long-term agreement that has a fixed purchase-price clause for a set minimum quantity, no price variance will arise when the purchase amount is below the minimum quantity (assuming the budgeted price per unit is the contract price per unit). A price variance will occur only when the purchased amount exceeds the set minimum quantity. A price variance signals that the purchased amount exceeds this set minimum quantity (2,400 kilograms per month). It is likely that the supplier will charge a higher price (above \$144) for purchases above the 2,400 base. If a lower price were charged, the purchaser might apply pressure to renegotiate the contract purchase price for the base amount. If the purchasing officer is able to negotiate only a small price increase for additional purchases above the base amount, the purchasing performance may well be “favourable” despite the materials price variance being labelled “unfavourable.” Metalmoulder may see the advantage of a long-term contract in factors other than purchase price (for example, a higher quality of materials, a lower required level of inventories because of more frequent deliveries, and a guaranteed availability of materials). In general, the existence of a long-term agreement reduces the importance of materials price variances when evaluating the month-to-month performance of a purchasing officer. In Class #7.3 Direct materials rate, efficiency, mix and yield variances Required 1 Calculate the total direct materials price and efficiency variances for November 2013. Solution Exhibit 7-3A presents the total rate variance (\$3,100F), the total efficiency variance (\$2,760U), and the total flexible-budget variance (\$340F).

Solution Exhibit 7-3B presents the total direct materials yield and mix variances for Greenwood Inc. for November 2013. The total direct materials yield variance can also be computed as the sum of the direct materials yield variances for each input: Direct  Budgeted total  Budgeted Budgeted  Actual total quantity of all  materials  quantity of all direct materials  direct price of yield variance      materials direct for each direct materials inputs allowed for  input mix materials  inputs used actual output  input  achieved  percentage inputs   Tolman = (310,000 – 300,000)  0.15  \$0.32 = 10,000  0.15  \$0.32 = \$ 480 U Golden Delicious = (310,000 – 300,000)  0.60  \$0.28 = 10,000  0.60  \$0.28 = 1,680 U Ribston = (310,000 – 300,000)  0.25  \$0.24 = 10,000  0.25  \$0.24 = 600 U Total direct materials yield variance \$2,760 U The total direct materials mix variance can also be computed as the sum of the direct materials mix variances for each input: Direct  Budgeted  Actual total Budgeted  Actual  materials  direct  quantity of price of  direct materials  mix variance  input mix  materials  all direct  direct for each  input mix  materials materials  percentage  input  percentage  inputs use d inputs Tolman = (0.20 – 0.15)  310,000  \$0.32 = 0.05  310,000  \$0.32 = \$4,960 U Golden Delicious = (0.50 – 0.60)  310,000 x \$0.28 = –0.10  310,000  \$0.28 = 8,680 F Ribston = (0.30 – 0.25)  310,000  \$0.24 = 0.05  310,000  \$0.24 = 3,720 U Total direct materials mix variance = \$ 0 U Required 3 Comment on your results in requirements 1 and 2. Greenwood paid less for Tolman and Ribston apples and, so, had a favourable direct materials rate variance of \$3,100. It also had an unfavourable efficiency variance of \$2,760. Greenwood would need to evaluate if these were unrelated events or if the lower price resulted from the purchase of apples of poorer quality that affected efficiency. The net effect in this case from a cost standpoint was favourable—the savin
