Why CPAs Need to Understand 409A Valuations?
As a CPA serving startup clients, you are often the professional who catches 409A compliance issues before they become expensive problems. Understanding the 409A requirement — and when to flag it to clients — is an essential part of startup advisory practice.
When to Recommend a 409A to Your Client?
Flag the 409A requirement when your client:
- Is setting up an employee option pool for the first time
- Is about to issue options to new hires and their current 409A is expired or missing
- Has closed a new funding round (priced or SAFE) — material event requiring a new 409A
- Has received an acquisition offer — material event
- Has not obtained a new 409A within the past 12 months
- Has experienced significant revenue growth or contraction — may trigger a new 409A depending on materiality
409A and ASC 718
For financial reporting purposes, ASC 718 requires companies to expense stock-based compensation at grant date fair value. The 409A FMV is a key input in calculating this expense using the Black-Scholes model:
- Stock price (S) — the 409A FMV per common share at grant date
- Exercise price (K) — must equal the 409A FMV (same as S for at-the-money options)
- Volatility (σ) — the 409A report should document the volatility assumption used
- Risk-free rate (r) — derived from US Treasury rates
- Expected term (T) — based on SAB 110 simplified method or historical data
A well-prepared 409A report provides all inputs needed for the ASC 718 calculation. Review the methodology section to ensure the volatility and DLOM assumptions are documented and supportable.
What to Look for in a 409A Report
When reviewing a client's 409A report for ASC 718 purposes, verify:
- Credentials — the report is signed by a CVA, ABV, or equivalent credentialed analyst
- Independence — the appraiser is independent from the company
- Methodology — DCF, GPC, and/or backsolve methods are documented
- OPM allocation — the report shows how enterprise value was allocated between preferred and common
- DLOM — the discount for lack of marketability is documented with support
- Volatility assumption — documented and based on peer companies
- Date — the effective date of the valuation is on or before the option grant date
Common 409A Issues You Will See in Practice
- Expired valuation — client continues granting options after the 12-month period
- Missing post-round valuation — client raised a Series A but did not update their 409A
- Instant/automated reports — client used a tool that produces a report without analyst review — not defensible
- Exercise price below FMV — options were granted at a price the board "felt was right" without an independent appraisal
