Auditing question

Segregation of duties is an important concept in internal control. However, segregation of duties is often a challenge for smaller businesses because they do not have sufficient staff to segregate duties. Normally, the segregation of duties identified below results in either a significant deficiency or a material weakness in internal control.

For each “segregation of duties: problem identified here:

a. Identify the risk to financial reporting that is associated with the inadequacy of the segregation of duties.

b. Identify other controls that might mitigate the segregation of duties risks.

c. If a control is identified that would mitigate the risks, briefly indicate what evidence the auditor would need to gather to determine that the control is operating effectively.


1. The same individual handles cash receipts, the bank reconciliation, and customer complaints.

2. The same person prepares billings to customers and also collects cash receipts and applies them to customer accounts.

3. The person who prepares billings to customers does not handle cash, but does the monthly bank reconciliation, which, in turn, is reviewed by the controller.

4. A start-up company has very few transactions, less than $1 million in revenue each year, and has only one accounting person. The company’s transactions are not complex.

5. The company has one computer person who is responsible for running packaged software. The individual has access to the computer to update software and can also access records.

Professional University

Professional University teaches a large range of undergraduate courses. It is interested in determining the cost equation for the facilities cost as a function of student credit hours so that it an more accurately budget its facilities costs as enrollment grows. Information for the high and low cost semesters and volumes for last 5 years appears below

Semester Student Credit Hours Facilities Cost
Spring 2007 250,000 $500,000
Fall 2004 300,000 $530,000

Using the high low method, with student credit hours as the activity driver, what is the equation for facilities cost (FC) as a function of student credit hours?

Assignment 2 Supply and Demand Concepts

As an economist for ABC Plastics, your boss has asked you to respond to some questions she has regarding the company’s main product, tablet cases. A marketing research firm recently developed the following supply and demand schedules for tablet cases:

Price/Case       Quantity Demanded        Quantity Supplied

$24                     5000                                 18000

22                       6000                                  17000

20                       7000                                  16000

18                       8000                                  15000
