| Net Income Per Share     | NOTE 9. Net Income Per ShareBasic netincome per share is computed by dividing net income by theweighted-average shares outstanding during the reporting period.Diluted net income per share is computed by dividing net income bythe combination of all dilutive common share equivalents, comprisedof shares issuable under the Corporation’s share-basedcompensation plans, and the weighted-average shares outstandingduring the reporting period.Dilutivecommon share equivalents include the dilutive effect ofin-the-money share-based awards, which are calculated based on theaverage share price for each period using the treasury stockmethod. Under the treasury stock method, the exercise price ofshare-based awards, the amount of compensation expense, if any, forfuture service that the Corporation has not yet recognized, and theamount of estimated tax benefits that would be recorded inadditional paid-in capital when share-based awards are exercised,are assumed to be used to repurchase common stock in the currentperiod.
