Stock Options: Design and Vesting

Overview

• What you’ll learn: How stock options are structured, the standard vesting schedule, tax implications, and how to communicate option value to employees who don’t think in financial instruments.

Introduction

The Grand Historian observes: The stock option is a peculiar gift — one that is worth nothing at the moment it is given, potentially worth a great deal at a moment years in the future, and dependent for its value entirely on events the recipient can influence but not control. As incentive designs go, this is either brilliant or cruel, depending on which company you joined in which year. Hu Baiyi is not sentimental about this: options are a bet. The company bets that it will grow. The employee bets their retained time on the same outcome. Design the bet clearly, or don’t offer it.

Core Design Elements

• Exercise price (strike price): The price at which the option holder can purchase shares. Typically set at the company’s current fair market value at the time of grant. If the company is worth ¥1,000 per share today, options are granted at ¥1,000. An employee exercising options when the company is worth ¥3,000 per share realizes a ¥2,000 per share gain.
• Grant size: Number of options granted. Varies by role — see Lesson 7 for allocation guidelines by level. Expressed as a percentage of fully diluted shares or as an absolute number.
• Vesting schedule: The standard in the industry is a four-year vesting schedule with a one-year cliff. This means: zero options vest for the first twelve months (the cliff), then 25% vest on the one-year anniversary, and the remaining 75% vest in equal monthly increments over the following 36 months. The cliff protects the company from granting equity to employees who leave within the first year.
• Expiry date: Options typically expire 10 years from the grant date, or 90 days after employment termination. The 90-day post-termination window is a deliberate pressure valve — it forces former employees to make an economic decision quickly rather than holding options indefinitely.

Tax Treatment

Tax treatment varies by jurisdiction and option type. In most regimes, the gain realized at exercise (market price minus exercise price) is treated as employment income, subject to full income tax rates. This is why employees are sometimes reluctant to exercise even profitable options — they face an immediate tax bill on paper gains before they can sell shares. Phantom share arrangements often have simpler tax treatment since the payment is simply a cash bonus.

Communicating Value to Employees

The practical challenge: most employees have never been taught to value an option. “You are receiving 500 options at ¥1,000 exercise price” means nothing to someone who has never bought a stock. The communication framework that works: convert to scenarios. “If the company doubles in value in four years, your 500 options would be worth approximately ¥500,000 before tax. If it triples, approximately ¥1,000,000. This assumes you are still employed at the four-year mark.” Concrete numbers, multiple scenarios, honest about the conditions. Do not use Black-Scholes in employee communications.

Key Takeaways

• Exercise price = fair market value at grant date. Gains occur when company value rises above this level.
• Standard vesting: 4-year total, 1-year cliff, then monthly over 36 months.
• Options expire 10 years from grant date or 90 days after termination.
• Communicate value through concrete scenarios, not financial formulas.
