Final answer:
The 'Appendix' is not a required section in an annual report, unlike the 'Introduction', 'Financial Statements', and 'Management Discussion and Analysis', which are standard and essential parts of the report.
Step-by-step explanation:
The section that is not required in an annual report is the Appendix. While the introduction, financial statements, and management discussion and analysis (MD&A) are standard sections of an annual report, the appendix is optional. The introduction typically provides a general overview of the company's operations and performance. The financial statements are essential and include the income statement, balance sheet, statement of cash flows, and statement of shareholders' equity, which communicate the financial health of the company. The MD&A offers management's perspective on the financial results and trends. An appendix, however, is supplementary and may include additional data or information that the company wishes to share but is not a mandatory component of the report.
