Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Accounting Policies | Accounting Policies In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments necessary for a fair statement of the results of operations and comprehensive income for the three and six months ended June 30, 2015 and 2014, the cash flows for the same six-month periods, and the financial position at June 30, 2015 and December 31, 2014, and except as otherwise discussed such adjustments consist of only those of a normal recurring nature. The interim results are not necessarily indicative of results for a full year and do not contain information included in the company’s annual consolidated financial statements and notes for the year ended December 31, 2014. Certain information and footnote disclosures, normally included in financial statements prepared in accordance with generally accepted accounting principles, have been condensed or omitted pursuant to SEC’s rules and regulations dealing with interim financial statements. However, the company believes that the disclosures made in the condensed consolidated financial statements included herein are adequate to make the information presented not misleading. It is suggested that these financial statements be read in conjunction with the financial statements and the notes thereto included in the company’s latest annual report on Form 10-K. Certain prior period amounts have been reclassified to conform to the current period presentation. All dollar amounts, except share and per share amounts, are in millions of dollars throughout the tables included in these notes unless otherwise indicated.
