New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements In January 2017, the FASB issued ASU 2017-04, "Goodwill and Other , Simplifying the Test for Goodwill Impairment" which simplifies the accounting for goodwill impairment. The new guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance will remain largely unchanged. This guidance is effective for annual periods beginning after December 15, 2019, and interim periods thereafter; however early adoption is permitted for any impairment tests performed after January 1, 2017. This guidance will only impact the Consolidated Financial Statements if there is a future impairment of goodwill. In February 2016, the FASB issued ASU 2016-02, "Leases," which replaces the current lease accounting standard. The update will require, among other items, lessees to recognize the assets and liabilities that arise from most leases on the balance sheet. This guidance is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods. The ASU must be adopted using a modified retrospective approach and early adoption is permitted. The Company is currently evaluating the impact of this update on its consolidated financial statements and disclosures. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers," which eliminates the transaction-and industry-specific revenue recognition guidance under current GAAP and replaces it with a principles-based approach for determining revenue recognition. The new guidance requires revenue recognition when control of the goods or services transfers to the customer, replacing the existing guidance which requires revenue recognition when the risks and rewards transfer to the customer. ASU 2014-09 (and related updates) is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods, with early adoption permitted for annual periods beginning after December 15, 2016. The Company intends to adopt this standard beginning August 1, 2018. Entities have the option of using either a full retrospective or a modified retrospective approach for the adoption of the standard. The Company is currently assessing the new guidance and whether to adopt using a full retrospective or a modified retrospective approach. Management is conducting surveys of its various business units and analyzing contracts and agreements during fiscal 2017 to ensure that all components of the new guidance are appropriately considered for the impact on its consolidated financial statements and disclosures upon adoption.
