Share-Based Payment Arrangement [Abstract]  
Stock-Based Compensation Stock-Based Compensation
The Corporation measures stock-based compensation expense at grant date, based on the fair value of the award. Forms of awards issued under shareholder-approved plans include stock options, restricted stock units based on a service condition ("restricted stock units"), restricted stock units based on both performance and service conditions ("performance stock units"), and shares issued under member stock purchase plans. Stock-based compensation expense related to stock options, restricted stock units, and performance stock units is recognized over the employees’ requisite service periods, adjusted for an estimated forfeiture rate for those shares not expected to vest. Additionally, expense related to performance stock units is periodically adjusted for the probable number of shares to be awarded based on Corporation achievement within an established target range of cumulative profitability over a multi-year period.

The following table summarizes expense associated with these plans:
