Share-based compensation programs, such as stock options and restricted stock, are integral components of employee and executive incentive structures. Their proper accounting and disclosure directly influence reported net income, equity, and the perceived cost of human capital.
Types of Share-Based Payment Arrangements
Share-based compensation arrangements can take various forms, including:
Stock options: Employees receive the right to purchase shares at a set exercise price during a specified period.
Restricted stock awards/units: Shares are granted subject to vesting conditions, such as continued employment or performance targets.
Employee stock purchase plans (ESPPs): Employees may purchase shares, often at a discount, via payroll deductions.
Each arrangement may have different vesting, performance, and service conditions that affect their accounting treatment.
Recognition and Measurement
Under US GAAP (ASC 718) and IFRS (IFRS 2):Share-based compensation cost is recognized as an expense over the vesting period, with a corresponding increase to equity (additional paid-in capital).
Grant-date fair value: The total compensation cost is measured at the grant date using an option-pricing model (e.g., Black-Scholes) for options, or market price for restricted stock.
Service/vesting period: Expense is recognized ratably (or as earned, if performance-based) over the requisite service period.

Option-Pricing Models and Fair Value Estimation
Estimating the fair value of options at the grant date typically involves models that consider:
Stock price at grant
Exercise price
Expected volatility
Risk-free interest rate
Expected dividend yield
Expected term until exercise
Assumptions must be disclosed, as they can significantly affect the reported expense.
Vesting Conditions and Modifications
Service conditions: Require continued employment for vesting.
Performance conditions: Vesting depends on achieving specified business targets.
Market conditions: Vesting depends on reaching share price or market index targets.
Forfeitures due to failure to meet vesting conditions are generally estimated at grant and updated for actual experience.
If terms are modified (e.g., exercise price reduced), incremental fair value is recognized as additional compensation cost.
Exercise, Forfeiture, and Expiry
Upon exercise of options, cash received is added to equity, and the amount in APIC—stock options is reclassified to common stock/APIC.
Forfeitures result in reversal of previously recognized compensation cost for unvested awards.
Expired options with no exercise result in reclassification within equity, with no income statement effect.
Disclosure Requirements
Both ASC 718 and IFRS 2 require comprehensive disclosure, including:
Description of plans and award terms
Number of shares, options, or units outstanding, granted, vested, exercised, or forfeited
Assumptions and methods for estimating fair value
Total share-based compensation expense recognized and effect on net income
Relevant Accounting Standards
