Description of New Accounting Pronouncements Not yet Adopted [Text Block]

Recently Issued Accounting Guidance

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842).  The ASU is the result of a project between the FASB and the International Accounting Standards Board to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements.  Upon adoption of the ASU, the Company will recognize lease assets and liabilities for its operating leases which are not currently reported on its consolidated balance sheets.  The ASU is effective for the Company for interim and annual periods beginning on or after January 1, 2019, with the ability to early adopt.  The Company is currently evaluating the effect of the ASU on its lease contracts.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.  The ASU replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates.  The ASU is effective for the Company for interim and annual periods beginning on or after January 1, 2020, with the ability to early adopt for interim and annual periods beginning on or after January 1, 2019.  The Company is currently evaluating the effect of the ASU on its financial assets measured at amortized cost.

New Accounting Pronouncements and Changes in Accounting Principles [Text Block]

Recently Adopted Accounting Guidance

In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606).  The ASU is the result of a convergence project between the FASB and the International Accounting Standards Board to clarify the principles for recognizing revenue and to develop a common revenue standard for GAAP and International Financial Reporting Standards.  The ASU removes inconsistencies and weaknesses in revenue requirements; provides a more robust framework for addressing revenue issues; improves comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets; provides more useful information to users of financial statements through expanded disclosure requirements; and simplifies the preparation of financial statements by reducing the number of requirements to which an entity must refer.  The Company retrospectively adopted the ASU on January 1, 2018.  The adoption of the ASU did not have a material impact on the Company's results of operations.  See Note 2 and "Changes in Accounting Policies" below.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.  The ASU enhances the reporting model for financial instruments by addressing certain aspects, including requiring equity investments to be measured at fair value with changes in fair value recognized in net income; simplifying the impairment assessment of equity investments without readily determinable fair values; eliminating the requirement to disclose the method and significant assumptions used to estimate the disclosed fair value of financial instruments measured at amortized cost; and requiring the use of the exit price notion for fair value measurements of financial instruments for disclosure purposes.  The Company adopted the ASU on January 1, 2018.  The Company recognized a cumulative-effect adjustment to January 1, 2018 retained earnings (accumulated deficit) of $1,801 for the cumulative change in fair value of available-for-sale equity investments previously recognized in other comprehensive income.  The adoption of the ASU did not have a material impact on the Company's results of operations.

In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.  The ASU amends the income statement presentation requirements of net periodic benefit cost of defined benefit pension and other postretirement plans.  The Company retrospectively adopted the ASU on January 1, 2018.  The adoption of the ASU did not have a material impact on the Company's results of operations.  See "Changes in Accounting Policies" below.
