The document discusses different types of audits: - Statutory audits are legally required reviews of a company's or government's financial records to determine if they provide an accurate representation of their financial position. - Non-statutory audits are voluntary and terms are agreed upon between the auditor and proprietor. - Internal audits are independent reviews conducted within an organization to evaluate risk management, controls, and governance processes. - Special audits are specifically requested to detect potential errors, irregularities, or fraud.
