Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements: In March 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-07, Compensation – Retirement Benefits (Topic 715). ASU 2017-07 improves the presentation of net periodic pension cost and net periodic postretirement benefit cost. Public business entities should apply the amendments in ASU 2017-07 for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years (i.e., January 1, 2018), early application is permitted. The Company does not expect the adoption of this standard to have a material effect on the Company’s consolidated financial position and results of operations. In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 350). ASU 2017-04 simplifies the test for goodwill impairment. Public business entities should apply the amendments in ASU 2017-04 for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years (i.e., January 1, 2020), early application is permitted. The Company does not expect the adoption of this standard to have a material effect on the Company’s consolidated financial position and results of operations. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230). ASU 2016-18 modifies the presentation of Restricted Cash on the Statement of Cash Flows. Public business entities should apply the amendments in ASU 2016-18 for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years (i.e., January 1, 2018), early application is permitted. The Company has not yet determined the effect of the adoption of this standard on the Company’s consolidated financial position and results of operations. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). ASU 2016-02 requires that a lessee recognize the assets and liabilities that arise from operating leases. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. Public business entities should apply the amendments in ASU 2016-02 for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years (i.e., January 1, 2019), early application is permitted. The Company is in the process of evaluating this pronouncement but has not yet determined the effect of the adoption of this standard on the Company’s consolidated financial position and results of operations. In August 2015, the FASB issued ASU 2015-14, which defers the effective date of ASU 2014-09, Revenue from Contracts with Customers (Topic 606) by one year. As a result, the ASU is now effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, which for the Company is the first quarter of 2018. Earlier application is permitted for fiscal years beginning after December 15, 2016, including interim reporting periods within those years, which for the Company is the first quarter of 2017. The Company is in the process of evaluating this pronouncement but does not expect the adoption of this standard to have a material effect on the Company’s consolidated financial position and results of operations. We will adopt the requirements of the new standard on January 1, 2018 and anticipate using the modified retrospective transition method. Under the modified retrospective method, we will recognize the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of retained earnings. The comparative information will not be restated and will continue to be reported under the accounting standards in effect for those periods. Presented below is the status of the process we have utilized for the adoption of the new standard and the significant implementation matters addressed: We established a team to assess all potential impacts of this standard. We are reviewing our current accounting policies and practices to identify potential differences that would result from the application of this standard. We are determining key factors to recognize revenue as prescribed by the new standard that may be applicable to each of our business segments. Customers and contracts from each business segment are being identified. Evaluation of the contract provisions and the comparison of historical accounting policies and practices to the requirements of the new standard (including the related qualitative disclosures regarding the potential impact of the effects of the accounting policies we expect to apply and a comparison to our current revenue recognition policies), is in process. We expect to complete this process prior to the filing of, and make disclosures in, our Annual Report on Form 10-K for the year ended December 31, 2017. Based on our evaluation so far, we believe there will be no significant changes required to our business processes, systems and controls to effectively report revenue recognition under the new standard. Adoption of the new standard is not expected to materially change the timing or amount of revenue recognized in our Consolidated Financial Statements.
