Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies: The accompanying unaudited condensed consolidated financial statements have been prepared on the basis of accounting principles generally accepted in the U.S. (“U.S. GAAP”). The preparation of financial statements in conformity with these accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant estimates include acquisition purchase price allocations, the fair value of goodwill, the realization of deferred tax assets, fair value of stock based compensation, liabilities for pension and postretirement benefits, and the estimate for the allowance for doubtful accounts. Actual results may ultimately differ from those estimates. Certain combinations have been made related to federal and state income taxes and to the segment reporting within revenue categories in the condensed consolidated financial statements and the notes to conform to the respective 2013 presentation. The condensed consolidated financial statements as of September 30, 2013 and for the three and nine months ended September 30, 2013 and 2012, in the opinion of management, include all adjustments, consisting of normal recurring accruals, to present fairly the Company’s financial position, results of operations and cash flows. The operating results for the three and nine months ended September 30, 2013 are not necessarily indicative of the results to be expected for the full year. The condensed consolidated financial statements and related notes for the three and nine months ended September 30, 2013 have been prepared on the same basis as and should be read in conjunction with the annual report on Form 10-K for the year ended December 31, 2012. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the rules of the Securities and Exchange Commission (“SEC”). The Company believes the disclosures made are adequate to keep the information presented from being misleading. Recent Accounting Pronouncements In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (“ASU No. 2013-02”). Under ASU No. 2013-02, an entity is required to provide information about the amounts reclassified out of accumulated other comprehensive income by component, either on the face of the financial statement where net income is presented or in the notes thereto. ASU No. 2013-02 is effective prospectively for reporting periods beginning after December 15, 2012. ASU 2013-02 was adopted by the Company on January 1, 2013. The Company elected to present the information as a separate disclosure in the notes to the condensed consolidated financial statements. Refer to Note 9 for further discussion. In February 2013, the FASB issued ASU No. 2013-04, Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date (“ASU No. 2013-04”). Under ASU No. 2013-04, an entity is required to measure and disclose the amounts and nature of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date. ASU No. 2013-04 is effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2013. Early adoption is permitted. The Company has elected not to early adopt this standard. The adoption of ASU 2013-04 will not have a material impact on the Company’s condensed consolidated financial statements as the long-term debt resulting from joint and several liability arrangements has been measured on a gross basis and disclosed in Note 8. Other obligations resulting from joint and several liability arrangements, such as contingencies, retirement benefits and income taxes, are excluded from the scope of this ASU. In March 2013, the FASB issued ASU No. 2013-05, Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity (“ASU No. 2013-05”). Under ASU No. 2013-05, an entity is required to release any related cumulative translation adjustment into net income upon cessation to have a controlling financial interest in a subsidiary or group of assets within a foreign entity. ASU 2013-05 is effective prospectively for fiscal years, and interim reporting periods within those years, beginning after December 15, 2013. Early adoption is permitted. The Company has elected not to early adopt this standard. The adoption of ASU 2013-05 is not expected to have a material impact on the Company’s condensed consolidated financial statements. In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU No. 2013-11”). Under ASU No. 2013-11, an unrecognized tax benefit should be presented as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, with the exception that these unrecognized tax benefits are not available at the reporting date to settle any additional income taxes that would result from the disallowance of a tax position or the tax law. An additional exception applies when the tax law does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, then the unrecognized tax benefit should be presented as a liability and should not be combined with deferred tax assets. ASU No. 2013-11 is effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2013. Early adoption is permitted. The Company has elected not to early adopt this standard. The Company is currently assessing the potential impact of ASU No. 2013-11 on its financial statements.
