In January 2017, the FASB issued guidance simplifying the accounting for goodwill impairment by removing Step 2 of the goodwill impairment test. Under current guidance, Step 2 of the goodwill impairment test requires entities to calculate the implied fair value of goodwill in the same manner as the amount of goodwill recognized in a business combination by assigning the fair value of a reporting unit to all of the assets and liabilities of the reporting unit. The carrying value in excess of the implied fair value is recognized as goodwill impairment. Under the new standard, goodwill impairment is recognized based on Step 1 of the current guidance, which calculates the carrying value in excess of the reporting unit’s fair value. The new standard is effective beginning in January 2020, with early adoption permitted. The Company does not believe the adoption of this guidance will have a material impact on the consolidated financial statements. In June 2016, the FASB issued guidance that introduces a new methodology for accounting for credit losses on financial instruments. The guidance establishes a new forward-looking "expected loss model" that requires entities to estimate current expected credit losses on accounts receivable and financial instruments by using all practical and relevant information. The guidance will be effective for the Company on January 1, 2020. Adoption of the standard will be applied using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the effective date. The Company does not believe the adoption of this guidance will have a material impact on the consolidated financial statements. In February 2016, the FASB issued guidance related to leases to increase transparency and comparability among organizations by requiring the recognition of right-of-use assets and lease liabilities on the balance sheet, while maintaining consistency with historical accounting for the recognition of expense on their income statements. Most prominent among the changes in the guidance is the recognition of right-of-use assets and lease liabilities by lessees for those leases classified as operating leases. Additional disclosures are required to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The Company adopted the updated guidance as of January 1, 2019 using a modified retrospective transition method with a cumulative-effect adjustment as of the adoption date, as permitted by the guidance. Comparative periods are not adjusted. See Note 2 of these consolidated financial statements for further details.
