What is a vesting schedule and cliff?

Vesting is a legal process where an employee earns the right to keep employer-provided assets over time. In the US and UK, this is standard for startup equity to align founder and employee interests with company growth. Without vesting, an individual could receive a large equity grant and resign the next day while keeping a significant portion of the company.

The schedule dictates the specific increments of time required to earn these rights. While stock options are the most common application, vesting can also apply to employer contributions in 401(k) plans in the US or pension schemes in the EU. It serves as a golden handcuff, incentivizing talent to stay through critical growth phases.

The cliff is a probationary period for equity. It ensures that employees who leave shortly after joining do not walk away with a piece of the cap table. A standard one-year cliff means that if an employee leaves at month eleven, they receive zero shares. If they stay for twelve months, they suddenly vest a large chunk - usually 25 percent of the total grant.

In India and the EU, cliff periods are strictly enforced in ESOP schemes to maintain stability. From a company perspective, it protects against bad hires, while for employees, it represents the first major milestone in their compensation package.

• Typical length is 12 months from the start date
• No shares are earned if termination occurs before the cliff
• Prevents cap table dilution from short-term turnover
• Usually triggers a lump-sum vest of the first year's portion
• Applies to both founders and early employees

The most common structure is a four-year linear vest with a one-year cliff. This means 25 percent vests at the one-year mark, followed by equal monthly installments for the remaining 36 months. However, some large tech firms use back-loaded schedules to maximize retention in later years.

A back-loaded schedule might vest 5 percent in the first year, 15 percent in the second, and 40 percent in each of the final two years. This significantly reduces the early value for the employee and makes leaving more expensive the longer they stay.

Acceleration refers to a scenario where the vesting process speeds up, often due to a major corporate event. Single-trigger acceleration occurs if the company is acquired, allowing employees to vest some or all remaining shares immediately. This is less common and often reserved for top executives.

Double-trigger acceleration is the industry standard. It requires two events: the company must be acquired, and the employee must be terminated without cause by the new owner. This protects the employee from being fired immediately after an acquisition while ensuring the acquiring company can retain talent.

• Single-trigger: Vests upon acquisition only
• Double-trigger: Vests upon acquisition plus termination
• Protects employees during mergers and buyouts
• Negotiable for senior management roles
• Prevents loss of equity due to corporate restructuring

Taxation is triggered at different points depending on the region. In the US, the 83(b) election allows employees to pay taxes on the fair market value of restricted stock at the time of the grant rather than when it vests, potentially saving significant money if the stock value rises.

In India, the difference between the Exercise Price and the Fair Market Value is taxed as a perquisite when shares are exercised. UK employees often look for EMI schemes which offer tax advantages for smaller companies. Always consult a tax professional to understand the liability created by a vesting event.
