Earnings Per Share [Abstract]  
Common Share Data
Common Share Data:

Earnings Per Share - Consolidated basic earnings per share excludes the dilutive effect of common stock equivalents and is computed by dividing income (loss) available to common stockholders by the weighted-average number of common shares actually outstanding for the year. Diluted earnings per share are similarly calculated with the inclusion of dilutive common stock equivalents. The following table provides a reconciliation of net income (loss) and the number of shares used in basic and diluted earnings per share calculations.

__________

(a) In calculating earnings per share, pertinent accounting rules require that common shares owned by the Company's Employee Savings and Stock Ownership Plan that are as yet unallocated to participants in the plan be excluded from the calculation. Such shares are issued and outstanding and have the same voting and other rights applicable to all other common shares.
