New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Description of New Accounting Pronouncements Not yet Adopted [Text Block]	NOTE N – NEW ACCOUNTING PRONOUNCEMENTS Periodically, new accounting pronouncements are issued by the FASB or other standard setting bodies. Recently issued standards typically do not require adoption until a future effective date. Prior to their effective date, we evaluate the pronouncements to determine the potential effects of adoption on our unaudited condensed consolidated financial statements. Standards to be Implemented ASC Update No. 2016-02 In February 2016, the FASB issued ASC Update No. 2016-02, Leases (Topic 842). The purpose of Update No. 2016-02 is to increase the transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet, including those previously classified as operating leases under current U.S. GAAP, and disclosing key information about leasing arrangements. Topic 842, as amended, is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods, with early adoption permitted. We currently plan to adopt the standard using the transition method provided by ASC Update No. 2018-11, Leases (Topic 842): Targeted Improvements. Under this method, we plan to initially apply the new leasing rules on January 1, 2019, and recognize the cumulative effect of initially applying the standard as an adjustment to our opening balance of retained earnings, rather than at the earliest comparative period presented in the financial statements. We have reached conclusions on several policy elections available under Topic 842 that we plan to apply on January 1, 2019. Upon transition, we will apply the package of practical expedients and will not reassess whether any expired or existing contracts are or contain leases, the classification of any expired or existing leases, and initial direct costs for any existing leases. We will apply the transition package of practical expedients described above to our entire lease portfolio at January 1, 2019. Furthermore, we have elected not to separate lease and non-lease components for the majority of our leases. Instead, for these applicable classes of underlying assets, we will account for each separate lease component, and the non-lease components associated with that lease component, as a single lease component. While we are still in the process of determining the effect that the new standard will have on our financial position and results of operations, we expect to recognize additional assets and corresponding liabilities on our consolidated balance sheets, as a result of our operating lease portfolio as it exists at the date we adopt the new standard on January 1, 2019. Please refer to Note F - Lease and Other Purchase Obligations in our most recent Annual Report on Form 10-K for information regarding our most current lease activity. Additionally, we are in the process of implementing a new lease administration and lease accounting system, and updating our controls and procedures for maintaining and accounting for our lease portfolio under the new standard. ASC Update No. 2016-13 In June 2016, the FASB issued ASC Update No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The purpose of Update No. 2016-13 is to replace the current incurred loss impairment methodology for financial assets measured at amortized cost with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information, including forecasted information, to develop credit loss estimates. Update No. 2016-13 is effective for annual periods beginning after December 15, 2019, including interim periods within those annual periods. Early adoption is permitted for annual periods beginning after December 15, 2018. We are in the process of determining the effect that the adoption will have on our financial position and results of operations. ASC Update No. 2018-09 In July 2018, the FASB issued ASC Update No. 2018-09, Codification Improvements. The purpose of Update No. 2018-09 is to clarify, correct errors in or make minor improvements to the Codification. The amendments make the Codification easier to understand and apply by eliminating inconsistencies and providing clarifications. The transition and effective date guidance is based on the facts and circumstances of each amendment. Some of the amendments in Update No. 2018-09 do not require transition guidance and are effective upon issuance. However, many of the amendments in Update No. 2018-09 do have transition guidance with an effective date of annual periods beginning after December 15, 2018. We are in the process of determining the effect that the adoption will have on our financial position and results of operations. ASC Update No. 2018-15 In August 2018, the FASB issued ASC Update No. 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The purpose of Update No. 2018-15 is to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Update No. 2018-15 is effective for annual periods beginning after December 15, 2019, including interim periods within those annual periods. Early adoption is permitted, including adoption in any interim period. We are in the process of determining the effect that the adoption will have on our financial position and results of operations. No other new accounting pronouncements, issued or effective, in the period had or are expected to have a material impact on our unaudited condensed consolidated financial statements.
