Equity-Based Compensation - We account for equity based compensation transactions with employees under the provisions of Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic No. 718, Compensation, Stock Compensation (Topic No. 718). Topic No. 718 requires the recognition of the fair value of equity-based compensation in net earnings. The fair value of common stock issued for compensation is measured at the market price on date of grant. The fair value of our equity instruments, other than common stock, is estimated using the Black-Scholes option valuation model. This model requires the input of highly subjective assumptions and elections including expected stock price volatility and the estimated life of each award. In addition, the calculation of equity-based compensation costs requires that we estimate the number of awards that will be forfeited during the vesting period. The fair value of equity-based awards granted to employees is amortized over the vesting period of the award and we elected to use the straight-line method for awards granted after the adoption of Topic No. 718.
We account for equity based transactions with non-employees under the provisions of ASC Topic No. 505-50, Equity-Based Payments to Non-Employees (Topic No. 505-50). Topic No. 505-50 establishes that equity-based payment transactions with non-employees shall be measured at the fair value of the consideration received or the fair value of the equity instruments issued, which ever is more reliably measurable. When the equity instrument is utilized for measurement the fair value of (i) common stock issued for payments to non-employees is measured at the market price on the date of grant; (ii) equity instruments, other than common stock, is estimated using the Black-Scholes option valuation model. In general, we recognize an asset or expense in the same manner as if it is to receive cash for the goods or services instead of paying with or using the equity instrument.
