Share-based Payment Arrangement [Abstract]
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	We recognize compensation expense for awards ratably over the requisite service period of the award, which is generally three years. We recognize compensation expense based on the number of awards expected to vest using an estimated average forfeiture rate. We calculate the fair value of stock-based awards based on the closing price on the date the award was granted for those awards with only service or performance conditions. For those awards with market conditions, we have determined the grant date fair value using the Monte Carlo simulation model.

Disclosure of accounting policy for award under share-based payment arrangement. Includes, but is not limited to, methodology and assumption used in measuring cost.
