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

(a) In calculating earnings per share, accounting standards require that common shares owned by the ORI 401(k) Savings and Profit Sharing Plan that are 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.
