Finding unknown amounts.

An auditor for the Internal Revenue Service is trying to reconstruct some partially destroyed records of two taxpayers. For each of the cases in the accompanying list, find the unknowns designated by the letters A through D.

Case 1
(in thousands) Case 2
Accounts receivable, 12/31 9,000 3,150
Cost of goods sold A 30,000
Accounts payable, 1/1 4,500 2,550
Accounts payable, 12/31 2,700 2,250
Finished goods inventory, 12/31 B 7,950
Gross margin 16,950 C
Work-in-process inventory, 1/1 0 1,200
Work-in-process inventory, 12/31 0 4,500
Finished goods inventory, 1/1 6,000 6,000
Direct materials used 12,000 18,000
Direct manufacturing labor 4,500 7,500
Manufacturing overhead costs 10,500 D
Purchases of direct materials 13,500 10,500
Revenues 48,000 47,700
Accounts receivable, 1/1 3,000 2,100

Question 2

Proration of overhead.

The Ride-On-Wave Company (ROW) produces a line of non-motorized boats. ROW uses a normal-costing system and allocates manufacturing overhead using direct manufacturing labor cost.

The following data are for 2014:

Budgeted manufacturing overhead cost 125,000
Budgeted direct manufacturing labor cost 250,000
Actual manufacturing overhead cost 117,000
Actual direct manufacturing labor cost 228,000

Inventory balances on December 31, 2014, were as follows:
2014 direct manufacturing
Account Ending balance labor cost in ending balance
Work in process 50,700 20,520
Finished goods 245,050 59,280
Cost of goods sold 549,250 148,200

Required:
1. Calculate the manufacturing overhead allocation rate.
2. Compute the amount of under- or overallocated manufacturing overhead.
3. Calculate the ending balances in work in process, finished goods, and cost of goods sold if under- or overallocated manufacturing overhead is as follows:
a. Written off to cost of goods sold
b. Prorated based on ending balances (before proration) in each of the three accounts
c. Prorated based on the overhead allocated in 2014 in the ending balances (before proration) in each of the three accounts
4. Which method would you choose? Justify your answer.

Answer to Question 1

Let G = given, I = inferred
Step 1: Use gross margin formula Case 1 Case 2
Revenues 48,000 G 47,700 G
Cost of goods sold A 31,050 I 30,000 G
Gross margin 16,950 G C 17,700 I

Step 2: Use schedule of cost of goods manufactured formula
Direct materials used 12,000 G 18,000 G
Direct manufacturing labor costs 4,500 G 7,500 G
Indirect manufacturing costs 10,500 G D 9,750 I
Manufacturing costs incurred 27,000 I 35,250 I
Add beginning work in process, 1/1 0 G 1,200 G
Total manufacturing costs to account for 27,000 I 36,450 I
Deduct ending work in process, 12/31 0 G 4,500 G
Cost of goods manufactured 27,000 I 31,950 I

Step 3: Use cost of goods sold formula
Beginning finished goods inventory, 1/1 6,000 G 6,000 G
Cost of goods manufactured 27,000 I 31,950 I
Cost of goods available for sale 33,000 I 37,950 I
Ending finished goods inventory, 12/31 B 1,950 I 7,950 G
Cost of goods sold 31,050 I 30,000 G
For case 1, do steps 1, 2, and 3 in order.
For case 2, do steps 1, 3, and then 2.

Answer to Question 2

=

2. Overhead allocated = 50 Actual direct manufacturing labor cost
= 50 228,000 = 114,000

Underallocated
manufacturing
overhead = Actual
manufacturing
overhead costs Allocated plant
overhead costs
= 117,000 114,000 = 3,000

Underallocated manufacturing overhead = 3,000

3a. All underallocated manufacturing overhead is written off to cost of goods sold.

Both work-in-process (WIP) and finished goods inventory remain unchanged.

Account Dec. 31, 2014
Balance
(Before Proration)
(1) Proration of 3,000
Underallocated

3b. Underallocated manufacturing overhead prorated based on ending balances:

551,200
Total 845,000 114,000 1.00 3,000 848,000

a,b,c Overhead allocated = Direct manuf. labor cost 50 = 20,520; 59,280; 148,200 50

4. Writing off all of the underallocated manufacturing overhead to Cost of Goods Sold (CGS) is usually warranted when CGS is large relative to Work-in-Process and Finished Goods Inventory and the underallocated manufacturing overhead is immaterial. Both these conditions apply in this case. ROW should write off the 3,000 underallocated manufacturing overhead to Cost of Goods Sold Account.
