Additionally, the new guidance requires cash flows related to excess tax benefits from stock-based compensation to be recognized with other income tax cash flows in operating activities, rather than separately as a financing activity.

Effective January 1, 2017, the Company adopted ASU 2017-04, Simplifying the Test for Goodwill Impairment, which was issued by the FASB. The guidance in the ASU simplifies certain aspects of the goodwill impairment test, including the elimination of the requirement to perform a qualitative assessment of the likelihood of a goodwill impairment for reporting units with a negative carrying value. All of the Company’s goodwill is included in the Registry Services reporting unit which has a negative carrying value. As a result, the Company will no longer be required to perform the qualitative assessment.

The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard will become effective for the Company on January 1, 2018. The FASB also issued several amendments to the standard, including clarification on accounting for licenses of intellectual property and identifying performance obligations. The Company’s evaluation of the new revenue guidance is substantially complete. The Company does not currently expect the adoption of the new revenue standard to have a material impact on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases. The guidance introduces a lessee model that requires most leases to be reported on the balance sheet. This ASU will become effective for the Company on January 1, 2019 and requires the modified retrospective transition method. The Company is currently evaluating the impact of this ASU on its consolidated financial statements and related disclosures.
