Net Operating Income		$ 2,587,370

Total operating assets at the end of the year are $20,700,000. The total operating assets at the end of last year was $19,800,000.

The company tracks its internal business process performance and reports the following data for this year:

Inspection time	0.6 days
Wait time (from order to start of production)	14.5 days
Process time	3.7 days
Move time	1.7 days
Queue time	4.3 days

Budgeted information for Northern Illinois is based on the following information:

           

Sales – Units	1,300,000
Sales Price	$12 per unit
Direct materials	$1.50 per unit
Direct labor	$3.60 per unit
Variable OH	$1.50 per unit
Variable S & A	$1.60 per unit
Fixed OH	$750,000
Fixed S & A	$1,125,000

The following standard cost card is for the variable manufacturing for one unit of production:

	Std Quantity	Std Price	Std Cost
Direct materials	2.00 lbs	0.75 per pound	1.50
Direct labor	0.20 hrs	18.00 per hour	3.60
Variable OH		1.50 per unit	1.50

During the year, the company purchased and used 2,772,000 pounds of material. The company worked 302,810 hours at a rate of $18 per hour.

The company’s minimum return is 10%.

This assignment requires several items to be completed using an Excel spreadsheet. Please prepare the items in the order given with the number of the requirement or your Excel spreadsheet.

1. Determine the ROI and RI for last year.

2. Determine last year’s throughput time, MCE, and delivery cycle time.

Please complete in excel.

Answer 1

1. Determine the ROI and RI for last year

Calculation of ROI (Return of Investment):

ROI = 2,587,370 / 1,98,00,000

= 13%

Calculation of RI (Residual Income):

RI = Operating Income - (Minimum required return * Operating Assets)

= 2,587,370 / (10% * 1,98,00,000)

= 607,370

B)

Determine last year’s throughput time, MCE, and delivery cycle time:

Calculation of Throughput time:

The throughput time of a product formula is calculated by adding the four steps of the manufacturing process: process time, inspection time, move time, and Queue time.

Throughput time = 3.7 days + 0.6 days + 1.7 days + 4.3 days

= 10.3 days

Calculation of MCE (Manufacturing cycle Efficiency):

Value added time as a percentage of throughput time is called manufacturing cycle efficiency.

Value Added Time = Process time

MCE = 3.7 days / 10.3 days = 36%

Calculation of Delivery Cycle time:

The amount of time from when an order is received from a customer to when the completed order is shipped is called delivery cycle time.

Delivery Cycle time = Wait time + Throughput time

= 14.5 days + 10.3 days

= 24.8 days
