Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation | Note 1B - Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in conformity with the instructions of the Securities and Exchange Commission (SEC) to Form 10-Q and SEC Regulation S-X, Article 10, Rule 10-01 for interim financial statements. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America (GAAP) for complete financial statements. In our opinion, the accompanying unaudited consolidated financial statements contain all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation. The results of operations and other data for the three and six months ended June 30, 2015 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2015. The unaudited consolidated financial statements presented herein should be read in conjunction with the audited consolidated financial statements and related notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2014.
Reclassifications | Reclassifications Within the Other income (expense) section of the unaudited Consolidated Statements of Operations for the three and six months ended June 30, 2014, we reclassified Interest income from Other, net to a separate line item to conform to the current year presentation. Certain insignificant amounts in the unaudited Consolidated Statements of Cash Flows for the six months ended June 30, 2014 have been reclassified to conform to the current year presentation. These reclassifications had no impact on our consolidated cash flows from operating, investing or financing activities.
Use of Estimates and Assumptions | Use of Estimates and Assumptions The preparation of financial statements in conformity with GAAP requires that management make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, the reported amounts of revenues and expenses during the reporting period and the related disclosures in the accompanying notes. Such estimates and assumptions include, but are not limited to, those that relate to fair value measurements, the provision for potential losses that may arise from litigation proceedings, and representation and warranty and other indemnification obligations. In developing estimates and assumptions, management uses all available information; however, actual results could materially differ from those estimates and assumptions.
Income Tax, Policy [Policy Text Block] | Income Taxes In accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 270, Interim Financial Reporting, and ASC 740-270, Income Taxes — Interim Reporting, at the end of each interim period, we are required to determine the best estimate of our annual effective tax rate and then apply that rate to “ordinary” income or loss (pretax income or loss excluding unusual or infrequently occurring discrete items) in providing for income taxes on an interim period. However, in certain circumstances where we are unable to make a reliable estimate of the annual effective tax rate, ASC 740-270 allows the actual effective tax rate for the interim period to be used in the interim period. For the second quarter ended June 30, 2015, we calculated our effective rate for the six months ended June 30, 2015 and applied that rate to the interim period results because we were unable to reasonably estimate our annual effective rate since small changes in estimated “ordinary” income would result in significant changes in the estimated annual effective tax rate. We determined the historical method would not provide a reliable estimate for the fiscal three and six months ended June 30, 2015.
Recently Issued Accounting Standards | Recently Issued Accounting Standards Business Combinations: Pushdown Accounting - Amendments to SEC Paragraphs Pursuant to Staff Accounting Bulletin No. 115 (ASU 2015-08) In May 2015, the FASB issued Accounting Standards Update (ASU) 2015-08, which removes references to the SEC’s Staff Accounting Bulletin (SAB) Topic 5.J on pushdown accounting from ASC 805-50, thereby conforming the FASB’s guidance on pushdown accounting with the SEC’s guidance on this topic. The SEC’s issuance of SAB No. 115 had superseded the guidance in SAB Topic 5.J in connection with the FASB’s November 2014 release of ASU 2014-17. ASU 2015-08 became effective for us upon issuance. Our adoption of ASU 2015-08 on May 11, 2015 did not have a material impact on our consolidated financial condition or results of operations.
