Accounting Policies [Abstract] |
Basis of Accounting, Policy [Policy Text Block] | Basis of Presentation These condensed Consolidated Financial Statements contain unaudited information as of June 30, 2013 and for the three- and six-month periods ended June 30, 2013 and 2012. The unaudited interim financial statements have been prepared pursuant to the rules and regulations for reporting on Form 10-Q. Accordingly, certain disclosures required by accounting principles generally accepted in the United States of America for annual financial statements are not included herein. In management’s opinion, these unaudited financial statements reflect all adjustments (which include only normal recurring adjustments) necessary for a fair presentation of the information when read in conjunction with our 2012 audited Consolidated Financial Statements and the related notes thereto. The financial information as of December 31, 2012 is derived from our 2012 Annual Report on Form 10-K. The interim condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and the notes thereto included in our 2012 Annual Report on Form 10-K. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for the full year.
Reclassification, Policy [Policy Text Block] | Reclassifications Certain reclassifications of amounts previously reported have been made to the accompanying consolidated financial statements to maintain consistency and comparability between periods presented. These reclassifications had no impact on previously reported net income.
