Your nephew, Sidney Short, has recently started work at High Five Marketing Inc. Sidney is majoring in marketing and is working with one of the production teams. You are with the finance and accounting department. During one of your regular coffee breaks together Sidney asks about the use of estimates when determining the company's net income. He says that he knows future revenues and expenses are estimates but does not understand why events that have already occurred cannot be measured accurately. He says he remembers from his introductory accounting course that there are accounting rules that cover how things must be accounted for, so he wants to know how net income that is in accordance with IFRS can be anything other than exact. Required Prepare the explanation you would give Sidney. Include an explanation of why estimates are necessary and how they these estimates are arrived at in organizations. As well, give two examples of where estimates are made in calculating revenue or expenses for an organization that follows IFRS. Note this is NOT an assessment opportunity. You do not need to quote any standards.
