(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.
