What is the difference between employee stock options and restricted stock?

Stock options give the right to buy shares at a set price, while restricted stock grants actual shares subject to vesting conditions. Both are equity-based compensation with different accounting treatments.

Employee Stock Options vs Restricted Stock

Both are equity-based compensation methods, but they work differently and have different accounting treatments.

Stock Options:

Gives employee the right to buy company shares at a fixed price (exercise price)
Employee must pay to exercise the option
Only valuable if stock price rises above exercise price
Can expire worthless if stock price doesn't increase

Restricted Stock:

Actual grant of shares to employee
Employee receives shares immediately (subject to vesting)
No payment required from employee (except possibly taxes)
Has value even if stock price decreases

Key Differences

Aspect	Stock Options	Restricted Stock
What is granted	Right to buy shares	Actual shares
Employee payment	Required to exercise	Usually not required
Value if stock falls	Can become worthless	Still has some value
Vesting period	Typically 3-5 years	Typically 3-5 years
Tax treatment	Taxed at exercise	Taxed at vesting
Dilution effect	Occurs when exercised	Occurs when granted

Example Comparison:

Stock Option:
• Grant 1,000 options at $50 exercise price
• If stock rises to $70: Gain = ($70 - $50) × 1,000 = $20,000
• If stock stays at $50: Options worthless

Restricted Stock:
• Grant 500 shares worth $50 each
• Value at grant: 500 × $50 = $25,000
• Even if stock falls to $40: Still worth 500 × $40 = $20,000

Accounting Treatment

Stock Options Accounting:

Grant Date: Estimate fair value using option pricing model
Vesting Period: Recognize expense evenly over vesting period
- Dr Compensation Expense
- Cr Additional Paid-in Capital
Exercise Date: Employee pays exercise price
- Dr Cash (exercise price)
- Dr Additional Paid-in Capital
- Cr Common Stock (par value)
- Cr Additional Paid-in Capital (balance)

Restricted Stock Accounting:

Grant Date: Fair value = market price on grant date
Vesting Period: Recognize expense over vesting period
- Dr Compensation Expense
- Cr Additional Paid-in Capital - Restricted Stock
Vesting Date: Shares become unrestricted
- Dr Additional Paid-in Capital - Restricted Stock
- Cr Common Stock

Important Notes:

Both require expense recognition under IFRS 2 / ASC 718
Expense based on fair value at grant date
Vesting conditions affect whether expense is recognized
Tax treatment differs for employees and company
Both dilute earnings per share calculations
