Auditor's Report

An auditor's report is a written opinion, issued by an independent accountant, stating whether a company's financial statements are presented fairly and in accordance with the applicable accounting standards.

What Is an Auditor's Report?

An auditor's report is the formal document that an independent auditor issues at the end of an audit. It sits alongside a company's financial statements, such as the balance sheet, income statement, and cash flow statement, and tells readers how much confidence they can place in those numbers. The report does not describe the company's performance or prospects. Its purpose is to state the auditor's professional opinion on whether the financial statements are reliable and free of material misstatement.

How It Works

An auditor examines the company's records, tests its internal controls, and checks a sample of transactions and balances against supporting evidence. When the work is complete, the auditor reaches one of several conclusions and states it in the report. The most common is an unmodified, or "clean," opinion, which means the statements are presented fairly in all material respects. Other outcomes include a qualified opinion, which points to a specific problem, an adverse opinion, which says the statements are not fairly presented, and a disclaimer of opinion, which means the auditor could not gather enough evidence to form a view at all.

Standard reports typically include an opinion section, a basis for the opinion, a description of the auditor's responsibilities, and management's responsibilities for the financial statements. In many cases they also include "key audit matters," which are the areas the auditor found most significant during the engagement, such as complex estimates or revenue recognition.

Why It Matters to Investors

Investors rely on the auditor's report as an independent check on management's own reporting. A clean opinion gives reasonable assurance that the figures used in ratios such as the price-to-earnings ratio or debt-to-equity ratio are reliable. A modified opinion, or the presence of a "going concern" paragraph warning that the company may not be able to continue operating, is a signal that deserves close reading. Such language often appears in the notes or risk sections of annual filings, and it can affect how a company's stock is valued.

Limitations

An audit provides reasonable assurance, not a guarantee. Auditors work on a sample basis and rely on information provided by management, so fraud or errors can sometimes go undetected. The report also says nothing about whether a stock is a good investment. Readers should treat it as one input among many, alongside the financial statements, footnotes, and the company's own management discussion.
