Employers are increasingly taking advantage of the motivational power of granting stock options as a form of compensation to key executives and employees. A stock option gives the employee the right to buy a specific number of shares within a certain period of time at a fixed price. If the employee chooses not to buy the shares, the option can expire unused.
Employers may grant two types of stock options: nonqualified options and incentive stock options (ISOs). Nonqualified options are not included in income unless the value is readily ascertainable. This usually means that the stock has to be traded on the open market.
ISOs are more complicated tax-wise and are rarer since an employer can take no tax deduction for them. While an employee may exercise an ISO without recognizing any taxable income, certain circumstances still create a tax. All income is recognized when the stock is sold.
Finding the value of stock options can be complex. The forensic accountant must usually determine the fair market value of the stock as well as the tax implications of receiving options, exercising them and selling the underlying stock.
Some Valuation Factors To Consider
Although forensic accountants have set up mathematical formulas to measure different aspects of stock option value, the process can still be somewhat subjective. Let's look at an option's time value. In theory, the forensic accountant could calculate the present value of the difference between the option's value at its expiration date and its exercise price. But the value at expiration would be an estimate, and the discount rate used would be up to the forensic accountant. Thus, different forensic accountants would likely derive different values for these options.
Academia Meets the Stock Market
Myron Scholes and Robert Merton won the Nobel Prize for Economics for developing and expanding a ground-breaking method for pricing stock options: the Black-Scholes option-pricing formula. The formula, initially conceived by Fischer Black and Myron Scholes, was first developed and published in 1973. Robert Merton later demonstrated the broad applicability of the model and extended its theoretical framework to encompass analysis of related financial instruments. Considered a pioneering formula for the pricing of stock, the Black-Scholes option-pricing formula led to a tremendous expansion of options markets.
The method was developed at a time when most investors and analysts were relying on guesswork to price options. The problem was how to evaluate the risk associated with options when the underlying stock price changes constantly. Black and Scholes realized that the risk was reflected in the stock price itself. They then created a formula that includes the stock price, the agreed sale or "strike" price of the option, the stock's volatility, the risk-free interest rate offered with a secure bond, and the time until the option's expiration. According to the formula, the value of the call option is given by the difference between the expected share value and the expected cost if the option is exercised at maturity. Thus, the Black-Scholes option-pricing model is considered a classic example of an academic innovation that has been adopted widely in practice.
Introducing Some Precision
Despite the unreliability of certain aspects of these calculations, forensic accountants try to introduce some precision and standardization by considering the following factors:
