What are Critical Audit Matters (CAMs)?

Written by Admin | February 13, 2026

If you’ve ever skimmed through an auditor’s report for a public company, you might have stumbled upon a section labeled "Critical Audit Matters" (CAMs). At first glance, it sounds like alarm bells should be ringing. But before you worry that something has gone wrong, it’s important to understand what this term actually means.

CAMs aren't necessarily signs of trouble. Instead, they highlight the complex, high-judgment areas of a business's finances—the parts that require the most brainpower to get right. Whether you run a public corporation or a private entity eyeing future growth, understanding these audit risks is a strategic move. It helps you prepare for mergers, attract investment, and simply understand where your financial reporting risks lie.

Let’s break down the basics of CAMs and why they matter to your bottom line.

What exactly are CAMs?

The Public Company Accounting Oversight Board (PCAOB) introduced these requirements under Auditing Standard (AS) 3101. In plain English, a Critical Audit Matter is any issue arising from the audit of financial statements that meets three specific criteria:

  1. It has been communicated to the audit committee.
  2. It relates to accounts or disclosures that are material to the financial statements.
  3. It involved especially challenging, subjective, or complex auditor judgment.

Think of CAMs as the "hard parts" of the audit. They highlight areas where the numbers weren't just black and white, but required estimates, assumptions, or sophisticated accounting treatments.

Crucially, CAMs are not errors, red flags, or signs of wrongdoing. They don't mean the financial statements are incorrect. They simply provide transparency, showing investors and stakeholders which areas of the financial report required significant professional judgment to verify.

Common examples of CAMs

While the guidance doesn't give a strict list of what must be a CAM, certain areas of accounting frequently pop up because they naturally involve more estimation and complexity.

Auditors must identify the CAM, explain why they selected it, and back it up with relevant financial data. Common issues include:

  • Revenue recognition: Deciding exactly when income is officially "earned" can be complex in long-term contracts.
  • Business combinations: Mergers and acquisitions often involve complicated accounting for assets and liabilities.
  • Goodwill and intangible asset valuation: Putting a price tag on a brand name or reputation involves significant estimation.
  • Tax positions: navigating uncertain tax positions or complex calculations.
  • Allowances and reserves: Any accounting that relies heavily on management’s judgment calls.

Do private companies need to worry about CAMs?

Technically, CAMs are a requirement for public company audits, not private ones. Public auditors began reporting these in 2019 to give shareholders more insight than the traditional pass/fail audit opinion.

However, just because you’re private doesn’t mean you should ignore the concept.

The underlying risks that create CAMs—like complex revenue models or hard-to-value assets—exist in private companies too. Your auditor is likely already evaluating these risks, even if they aren't slapping a "CAM" label on them in the final report.

Under standards set by the American Institute of Certified Public Accountants (AICPA), auditors still communicate significant risks and judgment-heavy areas to private business owners. You might hear about them in planning meetings or find them in management letters as recommendations for better internal controls.

Why private businesses should care

Understanding CAMs is particularly vital if you have ambitious plans for your business. If you are considering:

  • Going public (IPO)
  • Merging with a public company
  • Attracting sophisticated outside investors

...then CAM-type issues will almost certainly come up. Sophisticated investors and public partners will want to know about your high-judgment financial areas. Being proactive about these risks shows you have a handle on your financial strategy.

Turning insight into strategy

Ultimately, CAMs serve as a roadmap. They point out the twists and turns in your financial reporting where processes might need extra attention. This is especially true during periods of economic uncertainty or major business transactions.
