Accounting for Stock-Based Compensation

The stock-based compensation cost related to share-based liability awards is based on the fair value as of the measurement date. The compensation cost for equity instruments is measured based on the grant-date fair value at the date of issuance. Compensation cost is recognized over the periods that an employee provides service in exchange for the award. See Note 15 for further information.

We use the Monte Carlo valuation model to determine the fair value of all cash-settled awards where stock price is a factor in determining the vesting, as well as for cash or stock settled performance awards where there exists a similar stock price based market condition (we refer to these awards as “Market Condition Awards”). The Monte Carlo valuation model incorporates multiple input variables, including expected life, volatility, risk-free rate of return and dividend yield for each award to estimate the probability that a vesting condition will be achieved. In determining these assumptions for the Monte Carlo valuations, we consider historic and observable market data.

Depending on certain characteristics of the awards granted under the various compensation programs noted above, they are accounted for as either liabilities or equity instruments.

In 2013 and 2012, we used the Monte Carlo valuation model in determining the grant date fair value of performance-based stock options issued to executives and non-executives. Prior to 2012, we used the Black-Scholes valuation model in determining the grant date fair value of all stock options issued to executives, non-executives and non-employee directors.

We elected to apply the short-cut method in accounting for the windfall tax benefits under the accounting standard regarding share-based payment.
