New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
New Accounting Pronouncements And Changes In Accounting Principles [Text Block]	Adoption of New Accounting Pronouncements On April 1, 2019, we adopted ASU 2016-02, “Leases (Topic 842)” along with related updates, which require a lessee to recognize all leases with terms greater than 12 months on their balance sheet as a liability for its lease obligation, measured at the present value of lease payments not yet paid, and a corresponding asset representing its right to use the underlying asset over the lease term. The new leasing standard does not significantly change a lessee’s recognition, measurement and presentation of expenses and cash flows. Additionally, Topic 842 aligns key aspects of lessor accounting with the new revenue recognition guidance in Topic 606 (see ASU 2014-09 on the previous page) and expands disclosure of key information about leasing arrangements in an attempt to help financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases. We have determined portions of the vehicle rental contracts that convey the right to control the use of identified assets are within the scope of the accounting guidance contained in the new leasing standard. As we disclosed in our discussion of ASU 2014-09, the Company’s rental related revenues are accounted for under the revenue accounting standard Topic 606. Topic 842 maintains the dual model for lease accounting, requiring leases to be classified as either operating or finance, with lease classification determined in a manner similar to existing lease guidance. The basic principle is that leases of all types convey the right to direct the use and obtain substantially all the economic benefits of an identified asset, meaning they create an asset and liability for lessees. Lessees classify leases as either finance leases (comparable to current capital leases) or operating leases (comparable to current operating leases). Costs for a finance lease are split between amortization and interest expense, with operating leases reporting a single lease expense. Topic 842 substantially changed the accounting for sale-leasebacks going forward, where we are to assess if the contract qualifies as a sale under ASC 606. We have determined that our equipment sale-leasebacks do not qualify as a sale, as the buyer-lessors do not obtain control of the assets in our ongoing sale-leaseback arrangements. As a result, we expect future sale-leasebacks to be accounted for as a financial liability and the leased assets will be capitalized at cost. As all existing sale-leasebacks have been accounted for as a sale, we did not reassess any existing sale-leaseback transactions. We adopted the new leasing standard using the Effective Date Approach, which allows entities to only apply the new lease standard in the year of adoption. We elected the available practical expedients for existing or expired contracts of lessees and lessors wherein the Company is not required to reassess whether such contracts contain leases, the lease classification or the initial direct costs. Additionally, we elected as accounting policies to not recognize right of use assets or lease liabilities for short-term leases (i.e. those with a term of 12 months or less) and to combine lease and non-lease components in the contract for both lessee and lessor arrangements. Adoption of this standard resulted in most of our operating lease commitments being recognized as operating lease liabilities and right-of-use assets. Please see Note 8, Leases, of the Notes to Consolidated Financial Statements. In March 2017, the FASB issued ASU 2017-08, Receivables – Nonrefundable Fees and Other Cost (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities. These amendments shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in an interim period. If an entity early adopts in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes the interim period. The amendments should be applied on a modified retrospective basis, with a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The adoption of the standard did not have a material impact on our consolidated financial statements. Recent Accounting Pronouncements In June 2016, FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments. This standard requires the measurement and recognition of expected credit losses held at amortized cost. This new standard requires the use of forward-looking information to estimate credit losses and requires credit losses for available for sale debt securities to be recorded through an allowance for credit losses rather than a reduction in the amortized cost basis. This update is effective for public companies for annual reporting periods beginning after December 15, 2019. We are currently evaluating the impact of this standard on our consolidated financial statements. In August 2018, the FASB adopted ASU 2018-12, Targeted Improvements to the Accounting for Long-Duration Contracts (“ASU 2018-12”). The amendments in this update require insurance companies to annually review and update the assumptions used for measuring the liability under long-duration contracts, such as life insurance, disability income, and annuities. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 31, 2020. We are currently in the process of evaluating the impact of the adoption of this amendment on our financial statements; however, the adoption of ASU 2018-12 will impact the statements of operations because the effect of any update to the assumptions we used at the inception of the contracts will be recorded in net income. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which modifies the disclosures on fair value measurements by removing the requirement to disclose the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy and the policy for the timing of such transfers. ASU 2018-13 expands the disclosure requirements for Level 3 fair value measurements, primarily focused on changes in unrealized gains and losses included in other comprehensive income. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We are currently evaluating the impact of this update on our disclosures in the Notes to Consolidated Financial Statements. In August 2018, the FASB issued ASU 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General Subtopic 715-20 - Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans (“ASU 2018-14”), which amends ASC 715 to add, remove, and clarify disclosure requirements related to defined benefit pension and other postretirement plans. ASU 2018-14 is effective for fiscal years ending after December 15, 2020. We are currently evaluating the impact of this standard on our consolidated financial statements. From time to time, new accounting pronouncements are issued by the FASB or the SEC that are adopted by us as of the specified effective date. Unless otherwise discussed, these ASUs entail technical corrections to existing guidance or affect guidance related to specialized industries or entities and therefore will have minimal, if any, impact on our financial position or results of operations upon adoption.
