Share Option: An Employee Benefit and Financial Instrument

A share option is a financial instrument offered primarily as a benefit to employees. It provides the right, but not the obligation, to buy shares in the company at a pre-determined price or at a discount to the market price. Share options can serve as an incentive to align employees’ interests with those of shareholders.

1. Non-Qualified Stock Options (NSOs)

These are options that do not qualify for special tax treatments and are subject to ordinary income tax.

2. Incentive Stock Options (ISOs)

These are qualified for favorable tax treatment and are typically offered to employees. Gains are taxed at capital gains rates if certain conditions are met.

3. Enterprise Management Incentives (EMIs)

A scheme used primarily in the UK, aimed at smaller companies to offer tax-advantaged share options.

4. Savings Related Share Options Scheme (SAYE)

A scheme allowing employees to save regularly, and at the end of the period, use the savings to buy shares at a discounted price.

Detailed Explanation

Share options typically involve a “vesting period,” which is the time an employee must wait before they can exercise the option to buy shares. Once vested, the employee can purchase shares at the exercise price, which is often lower than the market price. Upon selling these shares, any profit made is subject to income tax.

Example of Share Option Calculation

An employee is granted options to buy 100 shares at $10 each. The current market price is $30 per share.

Total profit = \( $20 \times 100 \) shares = $2,000

Black-Scholes Model

The Black-Scholes formula is often used to estimate the fair value of share options:

Where:

• \( S_0 \) = current stock price
• \( X \) = exercise price
• \( t \) = time to maturity
• \( r \) = risk-free interest rate
• \( N(d) \) = cumulative distribution function of the standard normal distribution

Importance

• Employee Motivation: Aligns the interests of employees with those of shareholders.
• Retention: Helps in retaining key talent, particularly in tech and startup companies.
• Cash Flow Management: Allows companies to offer competitive compensation without immediate cash outflow.

Applicability

• Startups: Often used as a tool to attract and retain talent.
• Large Corporations: Used to reward employees and senior management.
• SMEs: Beneficial under schemes like EMIs.

Related Terms

• Strike Price: The fixed price at which an option can be exercised.
• Vesting Period: The period during which the employee cannot exercise the options.
