The audit report summarizes the auditor's findings and expresses an opinion on the company's financial statements. It should present a true and fair view of the company's affairs, be based on factual information, and contain suggestions for improvement. The audit report must include whether proper books were kept, financial statements agree with books, and statements comply with law. It concludes with the auditor's signature. A clean report means the auditor is satisfied, while a qualified report notes irregularities. Circumstances leading to qualification include improper books, non-compliance, incorrect valuations, and omitted facts. The audit certificate declares the statements' accuracy.
