QUESTION 1 (16 MARKS) You had been recently promoted to Senior Auditor of the audit firm Jose Rizal and Associates and was asked to consider the following independent situations:

A. Leanna David is part of the audit team for the current audit of Jupiter Pty Ltd (Jupiter). After 2 weeks at the client, he has advised you that he has been offered a job at Jupiter as soon as the current audit is finished.

B. One of your major clients, Just Squeeze Juice Pty Ltd, has talked to you about a consulting engagement next year for you to do a complete review of the adequacy of the entity's quality controls over the production of its fruit juices. However, the managing director has indicated that some of the Board are concerned about you taking up too much of their staff's time asking unnecessary questions. Therefore, he has suggested that your chances of getting the engagement will be significantly improved if you keep your questions of staff to a minimum during the current audit.

C. You have audited Avatar Pty Ltd, a stable engineering firm, for several years. At the start of this year, the finance director, Michelle Cruz, retired after 10 years with company and was replaced by Sherlon Dizon, a long-time friend of the audit manager Karlo Arcilla, who was best man at Sherlon's recent marriage
