2. During recent review, ABC Corporation discovered that it has a serious internal control problem,
It is estimated that the impact associated with this problem is $1 million and that the likelihood
is currently 5%. Two internal control procedures have been proposed to deal with this problem,
Procedure A would cost $25,000 and reduce likelihood 2%. Procedure B would cost $30,000 and
reduce likelihood to 1%. If both procedures were implemented, likelihood would be reduced to
0.1%.
Required :
A. What is the estimated expected loss associated with ABC Corporations internal control
problem before any new internal control procedure are implemented?
B. Compute the revised estimate of expected loss If procedure A were implemented, if
procedure B were implemented, and if both of procedure were implemented?
C. Compare estimated costs and benefits of procedure A, procedure B and both procedure
combined. If you consider only the estimates of cost and benefit, which procedures should
be implemented?
