New Accounting Pronouncements Or Change In Accounting Principle [Line Items]
New Accounting Pronouncement Or Change In Accounting Principle Description Of Prior period Information Retrospectively Adjusted	The FASB issued an accounting standard update in March 2017 to improve the presentation of net periodic pension and postretirement benefit cost. Defined benefit pension and postretirement benefit costs (“net benefit cost”) comprise several components that reflect different aspects of an employer’s financial arrangements as well as the cost of benefits provided to employees. This accounting standard update requires that an employer disaggregate the service cost component from the other components of net benefit cost, provides explicit guidance on how to present the service cost component and the other components of net benefit cost in the income statement and allows only the service cost component of net benefit cost to be eligible for capitalization. The guidance within this accounting standard update should be applied retrospectively for the presentation of the service cost component and the other components of net periodic benefit cost in the income statement and prospectively for the capitalization of the service cost component of net periodic benefit in assets. This accounting standard update is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted as of the beginning of an annual period for which financial statements (interim or annual) have not been issued or made available for issuance. During the first quarter of 2017, the Company elected to early adopt the guidance within this accounting standard update, including the use of a practical expedient which allows the Company to use amounts previously disclosed in its pension and other postretirement benefits note for the prior period as the estimation basis for applying the required retrospective presentation. Adoption of this guidance resulted in a reclassification to the Company’s Condensed Consolidated Statement of Income for the three and six months ended June 30, 2016, as previously reported cost of goods sold (“COGS”) were reduced by $0.2 and $0.3 million, respectively, and selling, general and administrative expenses (“SG&A”) were reduced by $0.4 million and $0.9 million, respectively, with a corresponding increase to other expense, net, of $0.6 million and $1.2 million, respectively.
