Auditing involves systematically obtaining and evaluating evidence regarding financial statements to determine how well they correspond to established criteria. Auditors are accountants who provide assurance by evaluating financial reports and issuing audit reports. There are different types of audits including financial, compliance, and internal audits. Auditors must comply with auditing standards and issue either unqualified opinions or modified opinions depending on if the financial statements are fairly presented. The objective is for auditors to form an opinion on whether financial statements are prepared according to the financial reporting framework.
