Selected Quarterly Financial Information (unaudited)

Note 18: Selected Quarterly Financial Information (unaudited)

The following table sets forth the historical unaudited quarterly financial data for the periods indicated. The information for each of these periods has been prepared on the same basis as the audited consolidated financial statements and, in our opinion, reflects all adjustments necessary to present fairly our financial results. Operating results for previous periods do not necessarily indicate results that may be achieved in any future period.
