Meaning
Tax risks arise when a company issues stock options with an exercise price below the fair market value of the underlying shares. Such section 409a exposure creates immediate tax liabilities and penalties for the option holder rather than the company itself. Founders must document their valuation methods to prove they avoided this outcome.
Valuation Standard
Maintaining a current appraisal of the company stock is the primary defense against internal revenue service audits. Any section 409a exposure is usually the result of using an outdated valuation or an informal pricing method. It represents a failure of financial diligence.
Financial Impact
Holders of mispriced options face a twenty percent federal penalty on top of ordinary income taxes on the spread between price and value. This section 409a exposure can create high costs for an employee if the paper gains are high but the stock is not yet liquid. The company must report these discrepancies, which can damage the trust of the workforce.
To avoid this, boards commission independent reports every twelve months or after any significant change in the business model. This expense is a standard cost of operating a venture backed entity.
Liability Risk
Founders often discover this problem during a sale when the buyer’s counsel reviews the option grants. Minimizing section 409a exposure is a requirement for a smooth acquisition.
