Nevertheless, there is included in Exhibit 20 hereto supplemental selected financial data based upon the consolidated financial statements of the registrant and Landmark. Such data has been restated for the dates and periods indicated to give effect to the acquisition using the pooling of interests method of accounting for business combinations. Such financial information is supplemental and does not include all the information and footnotes required by generally accepted accounting principles for complete financial statements and should be read in conjunction with the audited consolidated financial statements included in the registrant's 1995 Annual Report on Form 10-K. Moreover, such information may not necessarily reflect the results of operations or the financial position of the registrant that would have actually resulted had the acquisition occurred as of the date and for the periods indicated or be indicative of future results of operations of the registrant.
