ASU 2018-07 more closely aligns the accounting for employee and nonemployee share-based payments. This ASU is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2018. Early adoption is permitted. We do not expect the standard to have a material impact on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” ASU 2017-04 eliminates the two-step process that required identification of potential impairment and a separate measure of the actual impairment. The annual assessment of goodwill impairment will be determined by using the difference between the carrying amount and the fair value of the reporting unit.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”, which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. The new standard establishes a right-of-use model (ROU) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The new standard is effective for us on January 1, 2019, with early adoption permitted. We expect to adopt the standard on its effective date using the modified retrospective approach. The standard provides several optional practical expedients in transition. We expect to elect the ‘package of practical expedients’, which permits us to forgo reassessment of our prior conclusions about lease identification, lease classification and initial direct costs for periods prior to the effective date. Consequently, financial information will not be updated and the disclosures required under the new standard will not be provided for dates and periods before January 1, 2019. We do not expect to elect the use-of-hindsight or land easement practical expedients, the latter not being applicable to us. We anticipate this standard will have a material effect on our financial statements. While we continue to assess the effects of adoption, we believe the most significant effects will relate to the recognition of new ROU assets and liabilities on our balance sheet for vehicle and equipment leases, and new disclosures about our leasing activities. We do not expect a significant change in our leasing activities between now and adoption. In August 2018, the SEC adopted amendments to certain disclosure requirements in Securities Act Release No. 33-10532, “Disclosure Update and Simplification”. The amendments will become effective on November 5, 2018. Among the amendments is the requirement to present the changes in shareholders’ equity in the interim financial statements (either in a separate statement or footnote) in quarterly reports on Form 10-Q. This reporting requirement will be effective for us beginning with the quarterly report for the period ended March 31, 2019.

Adoption of New Accounting Standards

On January 1, 2018, we adopted Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers (Topic 606)” and all of the related amendments.
