Single-trigger RSUs vest on service alone and work for public companies because employees can immediately sell shares to cover the tax withholding. For private companies that creates a problem: employees receive shares they cannot sell but owe income tax on the full value, forcing them to find cash elsewhere. Double-trigger vesting solves this by adding a liquidity event requirement so shares are not delivered until employees can sell to cover their taxes, which is why virtually all late-stage Silicon Valley startups with significant 409A valuations use it.
Standard single-trigger RSUs vest based solely on continued service, with shares delivered at each vesting date. For public companies, this works because employees can immediately sell shares to cover the tax withholding obligation. For private companies, single-trigger vesting creates a significant problem: employees receive shares they cannot sell but owe income tax on the full fair market value. This forces employees to find cash from other sources to pay a tax bill on illiquid shares. Double-trigger vesting solves this by adding a liquidity event requirement, ensuring that shares are not delivered until employees have the ability to sell shares to cover their tax obligations. Gurpreet Bal notes that virtually all late-stage Silicon Valley startups with significant 409A valuations use double-trigger RSUs rather than single-trigger.
Double-trigger RSUs raise 409A challenges because settlement depends on a future liquidity event that may extend past the short-term deferral period, so the agreement must specify settlement timing with precision. The most common compliant structure requires settlement within a fixed period after the liquidity event, with that event defined to match a permissible 409A distribution event such as a change in control or an IPO under the short-term deferral rule. I advise companies to work with tax counsel to draft agreements that clearly specify settlement timing and triggers, since 409A errors can mean a 20% additional tax penalty plus interest for affected employees.
Double-trigger RSUs present significant Section 409A compliance challenges because the settlement date depends on the occurrence of a future event (the liquidity event) that may extend beyond the short-term deferral period. To comply with Section 409A, the RSU agreement must specify the settlement timing with precision. The most common compliant structure requires settlement within a fixed period after the liquidity event, with the liquidity event defined to correspond to a permissible 409A distribution event such as a change in control under Treasury Regulation 1.409A-3(i)(5) or an IPO under the short-term deferral rule. Gurpreet S. Bal advises companies to work with tax counsel to draft RSU agreements that clearly specify settlement timing and distribution triggers consistent with 409A requirements, as errors in 409A compliance can result in a 20% additional tax penalty plus interest for affected employees.
When the IPO or other qualifying liquidity event occurs, all RSUs that have met the service condition settle according to the agreement. Common approaches include immediate settlement on the event, settlement on a fixed date afterward such as the first trading day after lock-up expiration, or settlement in installments over a defined period. The timing affects both employee tax planning and the post-IPO stock price, since a large volume of shares hitting the market at once can create downward pressure. I advise companies to consider staggered settlement schedules that balance employee liquidity with market impact.
When the IPO or other qualifying liquidity event occurs, all RSUs that have satisfied the service condition will settle according to the terms of the RSU agreement. Common settlement approaches include immediate settlement upon the qualifying event, settlement on a fixed date following the event (such as the first trading day after the lock-up period expires), or settlement in installments over a defined period. The choice of settlement timing affects both employee tax planning and the company's post-IPO stock price, as a large volume of shares flooding the market simultaneously can create downward price pressure. Gurpreet Bal advises companies to consider staggered settlement schedules that balance employee liquidity needs with market impact considerations.
Under ASC 718 the liquidity event is treated as a performance condition, so expense is not recognized until the event is considered probable, which for most pre-IPO companies is not until the S-1 is filed or the company is otherwise clearly committed to an IPO. Once probability is established, the company must recognize a cumulative catch-up expense for all previously unvested RSUs, then recognize the remaining expense over the remaining service period. This catch-up can be substantial and can materially affect the S-1 financials, so I advise companies to model it early in IPO planning to avoid surprises.
Under ASC 718, the liquidity event in a double-trigger RSU is considered a performance condition. Stock-based compensation expense is not recognized until the liquidity event is considered probable. For most pre-IPO companies, the liquidity event is not considered probable until the company has filed its S-1 registration statement or is otherwise clearly committed to an IPO. When probability is established, the company must recognize a cumulative catch-up expense for all previously unvested RSUs, followed by ongoing recognition of remaining expense over the remaining service period. This catch-up expense can be substantial for companies with large RSU programs and can materially affect the financial statements included in the S-1. Gurpreet S. Bal advises companies to model the ASC 718 catch-up expense early in the IPO planning process to avoid surprises in the registration statement financials.
Double-trigger RSUs are standard and expected. What is often underappreciated is the importance of staggering the settlement schedule after the liquidity event. Delivering a large volume of shares to employees all at once — the moment the lock-up expires or the IPO closes — sends a signal to the market that insiders are ready to exit. That signal moves price downward. Staggering settlement over a defined period after the liquidity event is not just a tax and market mechanics consideration — it is a price signal. It communicates that the people closest to the company believe the stock is worth holding. Gurpreet's view is that getting the stagger right is one of the underrated decisions in IPO planning, and one that is worth discussing explicitly with counsel before the RSU agreements are finalized.
