Stock-based Compensation [Abstract]
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-Based Compensation Stock-based compensation expense for all stock-based compensation awards granted after July 1, 2006 is based on the grant-date fair value estimate in accordance with the provisions of the FASB issued guidance. The Company recognizes these compensation costs on a straight-line basis over the requisite service period of the award. Valuations are based on highly subjective assumptions about the future, including stock price volatility and exercise patterns. The fair value of share-based payment awards was estimated using the Black-Scholes option pricing model. Expected volatilities are based on the historical volatility of the Company's stock. The Company uses historical data to estimate option exercise and employee terminations. The expected term of options granted represents the period of time that options granted are expected to be outstanding. The risk-free rate for periods within the expected life of the option is based on the U.S. Treasury yield curve in effect at the time of the grant.
