New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	New Accounting Guidance Recently Adopted Accounting Standards In February 2016, the Financial Accounting Standards Board ("FASB") issued guidance that required lessees to put most leases on their balance sheets but recognize expenses on their income statements in a manner similar to today’s accounting. The guidance also eliminates today’s real estate-specific provisions and changes the guidance on sale-leaseback transactions, initial direct costs and lease executory costs for all entities. Lease classification will determine how to recognize lease-related revenue and expense. The Company adopted the new lease standard at January 1, 2019 using a simplified transition option that allows for a cumulative-effect adjustment in the period of adoption and therefore did not restate prior periods. The Company also elected to adopt the package of practical expedients which allows for existing operating leases to continue to be classified as operating leases under the new guidance without reassessing whether the contracts contain a lease under the new guidance or whether classification of the operating lease would be different under the new standard. The Company did not elect the use-of-hindsight practical expedient but did adopt the practical expedient pertaining to land easements which provides the option not to reassess whether land easements not previously accounted for as leases under prior leasing guidance would be leases under the new guidance. All of our leases at the adoption date were operating leases. As a result of the adoption of the new standard, the Company recognized operating lease liabilities of $51.2 million based on the present value of the remaining minimum rental payments and corresponding right-of-use assets of $51.1 million. Adoption of the new guidance did not impact retained earnings. Due to the adoption of the guidance using the retrospective cumulative-effect adjustment method, there are no changes to the Company's previously reported results prior to January 1, 2019. Lease expense is not expected to change materially as a result of adoption of the new guidance. The Company changed its disclosures related to leasing beginning in 2019, refer to Note 10. In August 2017, the FASB issued guidance that amends the hedge accounting rules to better portray the economic results of risk management activities in the financial statements and also to make targeted improvements to simplify the application of hedge accounting guidance. The guidance was adopted by the Company in the first quarter of 2019 and adoption did not have a material impact on our consolidated financial statements. In February 2018, the FASB issued guidance on the reclassification of certain tax effects from accumulated other comprehensive income. The guidance requires the Company to disclose a description of the Company’s accounting policy for releasing income tax effects from accumulated other comprehensive income and whether the Company elects to reclassify the stranded income tax effects from the Tax Cuts and Jobs Act, along with information about other income tax effects that are reclassified. The Company elected to early adopt this guidance during the fourth quarter of fiscal 2018. The Company had $20.2 million of net stranded income tax effects out of accumulated other comprehensive income and into retained earnings with no impact to total shareholders' equity or net income. Recently Issued Accounting Standards The Company considers the applicability and impact of all Accounting Standards Updates ("ASUs") issued by the FASB. The Company determined that all ASUs not yet adopted to be either not applicable or are expected to have minimal impact on the Company's consolidated financial statements.
