Quarterly Financial Information (Unaudited)

NOTE 13. Quarterly Financial Information (Unaudited)

The following table sets forth our unaudited consolidated statements of income data for each of the quarters in the two-year period ended December 31, 2013. The unaudited quarterly consolidated statements of income data set forth below have been prepared on the same basis as the audited consolidated financial statements included elsewhere in this Annual Report on Form 10-K and, in the opinion of management, reflect all necessary adjustments, which consist only of normal recurring adjustments, necessary for a fair presentation of such data. Our historical results are not necessarily indicative of the results for the full year or any other period. This data should be read together with our consolidated financial statements and the related notes included elsewhere in this Annual Report on Form 10-K.
