New Accounting Pronouncements Or Change In Accounting Principle [Line Items] |  |  |
New Accounting Pronouncement or Change in Accounting Principle, Description | In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses rather than incurred losses to estimate credit losses on certain types of financial instruments, including trade receivables. This may result in the earlier recognition of allowances for losses. The ASU is effective for public entities for fiscal years beginning after December 15, 2019, with early adoption permitted. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, which provided additional implementation guidance on the previously issued ASU. Management has not yet completed its assessment of the impact of the new standard on the Company’s Consolidated Financial Statements. Currently, the Company believes that the most notable impact of this ASU will relate to its processes around the assessment of the adequacy of its allowance for doubtful accounts on trade accounts receivable and the recognition of credit losses. In August 2018, the FASB issued ASU No. 2018-14, Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans, which amends ASC 715 to add, remove and clarify disclosure requirements related to defined benefit pension and other postretirement plans. The ASU is effective for public entities for fiscal years beginning after December 15, 2020, with early adoption permitted. Management has not yet completed its assessment of the impact of the new standard on the Company’s Consolidated Financial Statements. |  |

New Accounting Pronouncements Or Change In Accounting Principle [Line Items] |  |  |
New Accounting Pronouncement or Change in Accounting Principle, Description | In February 2016, the FASB issued Accounting Standards Update (ASU) 2016-02, Leases, which is intended to improve financial reporting about leasing transactions. The update requires a lessee to record on its balance sheet the assets and liabilities for the rights and obligations created by lease terms of more than 12 months. The update is effective for fiscal years beginning after December 15, 2018. A modified retrospective transition approach is required for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company elected to utilize a practical expedient in its method of adoption of the standard and adopted the guidance as of January 1, 2019. Under this expedient, which is a “current-period adjustment method,” the Company applied ASC 842 as of January 2019 and recognized operating lease liabilities of $11.7 million and right of use assets of $9.4 million for all leases with lease terms of more than 12 months. There was no impact to retained earnings as of that date. In addition, the Company adopted the guidance by electing the following practical expedients: (1) the Company did not reassess whether any expired or existing contracts contained leases, (2) the Company did not reassess the lease classification for any expired or existing leases, and (3) the Company excluded variable payments from the lease contract consideration and recorded those as incurred. The Company’s future commitments under lease obligations and additional disclosures are summarized in Note 12. |  |
