Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"), which will create a single, comprehensive revenue recognition model for recognizing revenue from contracts with customers. The standard is effective for interim and annual reporting periods beginning after December 15, 2017 and may be adopted either retrospectively or on a modified retrospective basis. The core principle of the new standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. ASU 2014-09 defines a five-step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than are required under existing guidance, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation, among others. The Company has established a cross-functional implementation team to evaluate and implement the new standard related to the recognition of revenue from contracts with customers. The Company primarily sells goods and recognizes revenue at point of sale or delivery and this will not change under the new standard. We are completing an analysis of revenue streams at each of the business units and are evaluating the impact the new standard may have on revenue recognition. In addition, the Company is evaluating recently issued guidance on practical expedients as part of the transition decision. The Company plans to use the modified retrospective adoption method and does not believe there will be a material impact to the Company’s consolidated revenues upon adoption. The Company will continue to evaluate the impacts of the pending adoption of ASU 2014-09 and the preliminary assessments are subject to change. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory ("ASU 2015-11"), which modifies existing requirements regarding measuring first-in, first-out and average cost inventory at the lower of cost or market. Under existing standards, the market amount requires consideration of replacement cost, net realizable value (“NRV”), and NRV less an approximately normal profit margin. ASU 2015-11 replaces market with NRV, defined as estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This eliminates the need to determine and consider replacement cost or NRV less an approximately normal profit margin when measuring inventory. The Company adopted ASU 2015-11 on January 1, 2017 and it did not have a material impact to the Company's condensed consolidated financial statements for the six months ended June 30, 2017 and it will not have a material impact on the annual consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) ("ASU 2016-02"), which requires an entity to recognize a right-of-use asset and a lease liability on the balance sheet for all leases, including operating leases, with a term greater than twelve months. Expanded disclosures with additional qualitative and quantitative information will also be required. This guidance is effective for interim and annual reporting periods beginning after December 15, 2018 and early adoption is permitted. The new standard must be adopted using a modified retrospective transition. The Company is currently evaluating the impact of ASU 2016-02 on its condensed consolidated financial statements and related disclosures. As disclosed in the leased properties footnote in the 2016 Annual Report on Form 10-K, the future minimum payments under noncancelable operating leases are approximately $865.0 million and the Company does believe the adoption of this standard will have a significant impact on the consolidated balance sheets. In March 2016, the FASB issued ASU 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09") that changes the accounting for certain aspects of share-based compensation to employees including forfeitures, employer tax withholding, and the financial statement presentation of excess tax benefits or expense. ASU 2016-09 also clarifies the statement of cash flows presentation for certain components of share-based compensation, which prospectively reclassifies cash flows from excess tax benefits of share-based compensation currently disclosed in financing activities to operating activities in the period of adoption. The guidance will increase income tax expense volatility, as well as the Company's cash flows from operations. In addition, the Company did not elect to change shares withheld for employment income tax purposes, or the current methodology of estimating forfeitures upon adoption. The Company adopted ASU 2016-09 on January 1, 2017 on a prospective basis. The adoption of ASU 2016-09 did not have a material impact to the Company's condensed consolidated financial statements for the six months ended June 30, 2017 and it is not expected to have a material impact on the annual consolidated financial statements or related disclosures. In March 2017, the FASB issued ASU 2017-07, Compensation-Retirement Benefits (Topic 715) ("ASU 2017-07"), which requires an entity to report the service cost component of net periodic benefit cost in the same line item as other compensation costs (selling, administrative and other expenses), and the remaining components in non-operating expense in the consolidated statement of income and comprehensive income. This standard is effective for interim and annual reporting periods beginning after December 15, 2017 and early adoption is permitted. The Company will adopt ASU 2017-07 on January 1, 2018 and it is not expected to have a material impact on the Company’s consolidated financial statements or related disclosures.
