New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Description of New Accounting Pronouncements Not yet Adopted [Text Block]	Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (FASB) issued guidance intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. The guidance is effective for annual periods, including interim periods within those periods, beginning after December 15, 2016, with early adoption permitted. We are currently evaluating the impact that the update will have on our results of operations, financial condition and financial statement disclosures. In February 2016, the FASB issued guidance requiring lessees to recognize a right-of-use asset and a lease liability on the balance sheet for substantially all leases, with the exception of short-term leases. Leases will be classified as either financing or operating, with classification affecting the pattern of expense recognition in the statement of income. The guidance is effective for annual periods, including interim periods within those periods, beginning after December 15, 2018 with early adoption permitted. We are currently evaluating the impact that the update will have on our results of operations, financial condition and financial statement disclosures. In January 2016, the FASB issued guidance related to the classification and measurement of financial instruments. The guidance primarily impacts the accounting for equity investments other than those accounted for using the equity method of accounting, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. Additionally, the FASB clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The accounting for other financial instruments, such as loans, investments in debt securities and financial liabilities is largely unchanged. The guidance is effective for annual periods, including interim periods within those periods, beginning after December 15, 2017 with early adoption permitted. We are currently evaluating the adoption methods and the impact that the update will have on our results of operations, financial condition and financial statement disclosures. In November 2015, the FASB issued guidance which simplifies the balance sheet classification of deferred taxes. The guidance requires that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. This guidance is effective for public business entities for annual periods, and for interim periods within those periods, beginning after December 15, 2016 with early adoption permitted. While the guidance will have an impact on our balance sheet classification, we do not anticipate it will have a material impact on our results of operations, financial condition or the financial statement disclosures. In April 2015, the FASB issued guidance related to customers accounting for fees paid in a cloud computing arrangement. The guidance provides clarification on whether a cloud computing arrangement includes a software license. If an arrangement includes a software license, then the software license element is accounted for consistent with the acquisition of other such licenses. If the arrangement does not include a software license, the arrangement is accounted for as a service contract. Entities have the option of adopting the guidance retrospectively or prospectively. The guidance is effective for annual periods, including interim periods within those periods, beginning after December 15, 2015 with early adoption permitted. We are currently evaluating both the adoption method and the impact that the update will have on our results of operations, financial condition and the financial statement disclosures. In February 2015, the FASB issued guidance which changes the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. Specifically, the amendments (1) modify the evaluation of whether limited partnerships with similar legal entities are variable interest entities (VIEs) or voting interest entities, (2) eliminate the presumption that a general partner should consolidate a limited partnership, (3) affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships and (4) provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. Entities have the option of using a full or modified retrospective approach to adopt the guidance. This guidance is effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015 with early adoption permitted. We do not anticipate it will have a material impact on our results of operations, financial condition or the financial statement disclosures. In May 2014, the FASB issued guidance which outlines a single comprehensive revenue model for entities to use in accounting for revenue arising from contracts with customers. The guidance supersedes most current revenue recognition guidance, including industry-specific guidance, and requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. Entities have the option of using either a full retrospective or modified approach to adopt the guidance. In June 2015, the FASB deferred the effective date of the guidance by one year. This guidance is now effective for annual and interim reporting periods beginning after December 15, 2017, and early adoption is now permitted for annual and interim reporting periods beginning after December 15, 2016. In March and April 2016, the FASB issued further guidance that clarifies certain implementation issues related to revenue recognition, including principal versus agent considerations, the identification of performance obligations and licensing. These additional updates have the same effective date as the new revenue guidance. We are currently evaluating the adoption methods and the impact that the update will have on our results of operations, financial condition and financial statement disclosures.
