New Accounting Pronouncements [Abstract]
New Accounting Pronouncements	In March 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2017-07, Retirement Benefits – Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This guidance requires entities to present the service cost component of net periodic pension cost and net periodic postretirement benefit cost in the income statement line items where they report compensation cost. Entities will present all other components of net benefit cost outside operating income, if this subtotal is presented. The rules related to the timing of when costs are recognized or how they are measured have not changed. This amendment only impacts where those costs are reflected within the income statement. In addition, only the service cost component will be eligible for capitalization in inventory and other assets. This guidance became effective January 1, 2018. The adoption of this new standard did not have a material impact on the Company’s consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, a consensus of the FASB’s Emerging Issues Task Force (the “Task Force”). The new standard requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Entities will also be required to reconcile such total to amounts on the balance sheet and disclose the nature of the restrictions. This update is effective for years beginning after December 31, 2018. The Company has restricted cash balances and anticipates that the adoption of this new standard will change the cash amounts and financing activities on its statement of cash flows on its consolidated financial statements. In February 2016, the FASB issued its final standard on accounting for leases. This standard, issued as ASU 2016-02, requires that an entity that is a lessee to recognize lease assets and lease liabilities on the balance sheet for all leases and disclose key information about leasing arrangements. This update is effective for financial statement periods beginning after December 15, 2018, with earlier application permitted. The Company has not yet determined the impact of this pronouncement on its consolidated financial statements and related disclosures, but anticipates it will be required to record additional lease liabilities and corresponding rights to use assets.
