Chapter 4 Mini Case 2 Ratios and Financial Planning at S & S Air

Chris Gumede was recently hired by S&S Air to assist the company with itsfinancial planning and to evaluate the company’s performance. Chris graduatedfrom university five years ago with a finance degree.S&S Air was founded 10 years ago by friends Mark and Thandi. Thecompany has manufactured and sold light aeroplanes over this period and thecompany’s products have received high reviews for safety and reliability. Thecompany has a niche market in that it sells primarily to individuals who own andfly their own aeroplanes. The company has two models, the Birdie which sells forR2 530 000 and the Eagle which sells for R5 780 000.While the company manufactures aircraft, its operations are different fromcommercial aircraft companies. S&S Air builds aircraft to order. By usingprefabricated parts, the company is able to complete the manufacture of anaeroplane in only five weeks. The company also receives a deposit on each order,as well as another partial payment before the order is complete. In contrast, acommercial aeroplane may take one and a half to two years to manufacture oncethe order is placed.Mark and Thandi have provided the following financial statements. Chris hasgathered the industry ratios for the light aeroplane manufacturing industry.

Questions

1. Calculate the following ratios for S&S Air: current ratio, quick ratio, cashratio, total asset turnover, inventory days, receivables days, total debt ratio,debt-equity ratio, equity multiplier, times interest earned, cash coverage,profit margin, return on assets and return on equity.

2. Mark and Todd agree that a ratio analysis can provide a measure of thecompany’s performance. They have chosen Boeing as an aspirantcompany. Would you choose Boeing? Why or why not?

3. Compare the performance of S&S Air to the industry. For each ratio,comment on why it might be viewed as positive or negative relative to theindustry. Suppose you create an inventory ratio calculated by inventorydivided by current liabilities. How do you think S&S Air’s ratio wouldcompare to the industry average.

4. Calculate the internal growth rate and sustainable growth rate for S&S Air.What do these numbers mean?

5. S&S Air is planning for a growth rate of 20 per cent next year. CalculateEFN assuming the company operated at full capacity in 2008.

6. Although most assets can be increased as a percentage of sales, net non-current assets often must be increased in specific amounts since it isusually impossible or impractical to buy part of a new plant or machine.So, assume S&S Air cannot increase net non-current assets as a percentageof sales. Instead, whenever the company needs to purchase newmanufacturing equipment, it must purchase in the amount of R30 000 000. Calculate the new EFN with this assumption. What doesthis imply about capacity utilization for the company next year?

Consider a population that consists of the 70 students enrolled in a statistics course at a large university. If the university registrar were to compile the grade point averages (GPAs) of all 70 students in the course and compute their average, the result would be a mean GPA of 2.98. Note that this average is unknown to anyone; to collect the GPA information would violate the confidentiality of the students’ academic records.

Suppose that the professor who teaches the course wants to know the mean GPA of the students enrolled in her course. She selects a sample of students who are in attendance on the third day of class. The GPAs of the students in the sample are:

1) The instructor uses the sample average as an estimate of the mean GPA of her students. The absolute value of the error in the instructor’s estimate is:

a) 0.52

b) 0.62

c) 0.86

d) 0.80

The portion of this error that is due to errors in data acquisition, nonresponse bias, and selection bias is referred to as 2) non sampling error/sampling error. This type of error is 3) more/less serious than 4) non sampling error/sampling error because taking a larger sample 5) will diminish/will not diminish its size or possibility of occurrence.

Suppose students in the university’s honors program are on a field trip on the third day of class. This may have introduced an 6) error in data acquisition/selection bias/a non response error/sampling error . Correcting this error will 7) sometimes/always/never bring the sample closer to the true mean GPA.

Suppose that the instructor incorrectly recorded the value 3.74 in the data and that the correct value is 3.47. This contribution to the error was caused by 8) error in data acquisition/selection bias/a non response error/sampling error. Given the instructor’s sample, correcting this error would bring the sample mean 9) Closer to the true mean GPA/Farther from the true mean GPA/To the exact value of the true mean GPA.

Suppose a student who was selected for the sample declines to disclose her GPA. This may have introduced 10) error in data acquisition/selection bias/a non response error/sampling error. Correcting this error will 11) sometimes/always/never bring the sample closer to the true mean GPA.

The professor suspects that her sample is flawed. She assigns each of the students in the class an ID number from 1 to 70 and uses Excel to select a simple random sample of ID numbers. The professor meets with the students in the sample. Each student signs a release that gives the registrar permission to use the student’s GPA to compute the sample average. The professor assures the students that the registrar will provide her with the average and not the GPAs of individual students.

The GPAs of the students in the new sample (from their academic records held by the registrar) are:

12) The professor uses the new sample average provided by the registrar as an estimate of the mean GPA of the students in the course. The absolute value of the error in her estimate is:

a) 0.42

b) 0.26

c) 0.01

d) 0.55

This error is 13) non sampling error/sampling error , and the only way to reduce its expected size is to 14) increase/decrease the sample size.
