Accounting Policies [Abstract]
Fair Value of Financial Instruments	The fair values of cash and cash equivalents, receivables and payables was approximately the same as their presented carrying values because of the short maturities of these instruments. The fair value of long-term debt is provided in Note 8, and the fair values of derivative financial instruments are provided in Note 11.
Net Loss Attributable to Company Per Share	Companies with unvested participating securities are required to utilize a two-class method for the computation of net income attributable to Company per share. The two-class method requires a portion of net income attributable to Company to be allocated to participating securities, which are unvested awards of share-based payments with non-forfeitable rights to receive dividends or dividend equivalents, if declared. Net income (loss) attributable to Company allocated to participating securities was immaterial for each of the three and six months ended June 30, 2019 and 2018.
Recently Adopted and Issued Accounting Standards	Recently Adopted Accounting Standards In August 2017, the FASB issued Accounting Standard Update No. 2017-12 “Derivatives and Hedging – Targeted Improvements to Accounting for Hedging Activities” (ASU 2017-12). This update improves the financial reporting of hedging relationships and simplifies the application of the hedge accounting guidance. ASU 2017-12 is effective for fiscal periods beginning after December 15, 2018, and for interim periods within those fiscal years. The Company adopted this update on January 1, 2019, with no material impact. In March 2016, the FASB issued ASC Topic 842, “Leases” (ASC Topic 842), which supersedes the lease requirements in ASC Topic No. 840 “Leases” and most industry-specific guidance. This update increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. ASC Topic 842 is effective for fiscal years beginning after December 15, 2018, and for interim periods within those fiscal years. The Company adopted ASU Topic 842 on January 1, 2019. Refer to Note 7, Leases, for the impact of this adoption on the Company’s financial statements. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which allows for a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the U.S. Tax Cuts and Jobs Act (the “Tax Act”). The Company adopted ASU Topic 2018-02 on January 1, 2019 and elected not to reclassify stranded tax effects caused by tax reform from AOCI to retained earnings. Recently Issued Accounting Standards In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (ASC Topic 326): Measurement of Credit Losses on Financial Instruments. This update improves financial reporting by requiring earlier recognition of credit losses on financing receivables and other financial assets in scope. ASU 2016-13 is effective for fiscal periods beginning after December 15, 2019, including interim periods within those fiscal years. The Company is currently evaluating the effect of adopting this standard.
