Public Company Audit FAQs
What is a PCAOB audit and why is it required for public companies?
The Public Company Accounting Oversight Board (PCAOB) sets auditing standards for companies registered with the SEC. All SEC-registered public companies must use a PCAOB-registered auditor. PCAOB audits involve stricter independence requirements, additional quality control procedures, and more comprehensive documentation than standard GAAS audits. GreenGrowth CPAs is PCAOB registered.
What is the difference between PCAOB and CPAB audits?
PCAOB is the US standard for SEC-registered companies. CPAB (Canadian Public Accountability Board) is the equivalent Canadian body for companies listed on Canadian exchanges. GreenGrowth CPAs is registered with both, supporting public companies listed in both the US and Canada.
What SOX compliance services does GreenGrowth CPAs provide?
GreenGrowth CPAs provides SOX Section 404 readiness assessments, internal control documentation, control testing, gap analysis, and ongoing compliance support. We work with management and Boards to build control frameworks that meet regulatory standards and reduce deficiency risk.
Does GreenGrowth CPAs have experience with cannabis public companies?
Yes. GreenGrowth CPAs is one of the most experienced public company audit firms in the cannabis sector, having supported cannabis operators through US and Canadian public listings, ongoing SEC and CSE/TSX reporting requirements, and complex accounting matters specific to regulated cannabis businesses.
How long does a public company audit typically take?
A PCAOB or CPAB audit for a public company typically takes 8 to 16 weeks from kick-off to issued opinion, depending on company size, complexity, and audit history. Interim fieldwork is often performed throughout the year, with year-end fieldwork concentrated after the close. Companies with strong internal controls, clean accounting records, and recent audit history experience shorter timelines than first-year public companies or those with material complexity.
When should a private company start preparing for its first public company audit?
Companies preparing for an IPO or going-public transaction should start audit readiness work 12 to 24 months before the offering. PCAOB audits require three years of audited financials, typically prepared under elevated standards. Preparation includes internal controls documentation, accounting policy alignment with GAAP, revenue recognition under ASC 606, stock-based compensation under ASC 718, and addressing technical accounting areas that will be heavily scrutinized.
