Interim Financial Information

The accompanying unaudited consolidated condensed financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for annual financial statements. Results for the period ended June 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013.

The consolidated condensed financial statements and notes thereto should be read in conjunction with the financial statements and notes for the year ended December 31, 2012 included in our Annual Report on Form 10-K.

Income taxes receivable and income taxes payable at December 31, 2012 have been revised to conform to the current year presentation.
