CY2012	us-gaap	Share Based Compensation Arrangement By Share Based Payment Award Fair Value Assumptions Method Used ShareBasedCompensationArrangementByShareBasedPaymentAwardFairValueAssumptionsMethodUsed	We estimate the fair value of each option on the grant date using a Black-Scholes option-pricing model, which requires us to make predictive assumptions regarding future stock price volatility, employee exercise behavior, and dividend yield. We estimate our future stock price volatility using the historical volatility over the expected term of the option, excluding time periods of volatility we believe a marketplace participant would exclude in estimating our stock price volatility. We also have considered, but did not use, implied volatility in our estimate, because trading activity in options on our stock, especially those with tenors of greater than 6 months, is insufficient to provide a reliable measure of expected volatility. Our expected term represents the period of time that options granted are expected to be outstanding based on historical data to estimate option exercises and employee terminations within the valuation model. Separate groups of employees have similar historical exercise behavior and therefore were aggregated into a single pool for valuation purposes. The weighted-average expected term for all employee groups is presented in the table above. The risk-free interest rate for periods during the expected term of the options is based on the U.S. Treasury zero-coupon yield curve in effect at the time of grant.

Certain restricted stock and restricted stock unit awards require the employee to deposit personally owned shares (on a one-for-one basis) during the restricted period. Restricted stock and restricted stock units generally vest and become unrestricted four years after the date of grant. Participants are entitled to dividends on such awarded shares and units, but only receive those amounts if the shares or units vest. The sale or transfer of these shares and units is restricted during the vesting period. Participants holding restricted stock, but not restricted stock units, are entitled to vote on matters submitted to holders of common stock for a vote.
