New Accounting Standards and Accounting Policy	2. New Accounting Standards and Accounting Policy In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-04, “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” which simplified the testing of goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measured a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. ASU 2017-04 is effective for public companies for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. We are currently evaluating the effects that the adoption of ASU 2017-04 will have on our consolidated financial statements. In February 2018, the FASB issued ASU No. 2018-02, “Income Statement — Reporting Comprehensive Income (Topic 220) — Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” ASU 2018-02 allows for a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the enactment of the U.S. Tax Cuts and Jobs Act (“the Act”). The update also requires entities to disclose whether or not they elected to reclassify the tax effects related to the Act as well as their accounting policy for releasing income tax effects from accumulated other comprehensive income. ASU 2018-02 is effective for financial statements issued for annual periods beginning after December 15, 2018, and interim periods within those annual periods, with early adoption permitted. We did not adopt the optional guidance of this accounting standard update as the potential impact on our consolidated financial statements is not material. Adoption of New Lease Accounting Standard In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASC 842”), which requires lessees to recognize right-of-use (“ROU”) assets and lease liabilities, initially measured at present value of the lease payments, on its balance sheet for leases and classified as either financing or operating leases. The new lease standard is effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We adopted ASC 842 on January 1, 2019, using the modified retrospective method, and we elected the package of practical expedients provided in ASC 842. In accordance with ASC 842, we did not restate comparative periods and instead reported comparative periods under ASC 840, “Leases.” We recorded operating lease ROU assets of $33.7 million as part of “Other assets” and corresponding lease obligations of $4.9 million and $32.3 million as part of “Accrued expenses and other current liabilities” and “Other long-term liabilities,” respectively, on our consolidated balance sheet upon adoption of ASC 842 on January 1, 2019. There was no material impact to our consolidated statement of operations and no cumulative effect adjustment to our retained earnings upon adoption of ASC 842. See Note 5 below for more information. Lease Accounting Policy ROU assets represent our right to use an underlying asset during the reasonably certain lease term and lease liabilities represent our obligation to make lease payments arising from the lease. We recognize ROU lease assets and lease liabilities at lease commencement on our consolidated balance sheet based on the present value of lease payments over the lease term using a discount rate determined based on our incremental borrowing rate since the rate implicit in each lease is not readily determinable. We elected the package of practical expedients, which permits us to not reassess (1) whether any expired or existing contracts are or contain leases, (2) the lease classification of any expired or existing leases, and (3) any initial direct costs for any existing leases as of the effective date. We elected the practical expedient to account for each separate lease component of a contract and its associated non-lease components as a single lease component. We also elected the hindsight practical expedient, which allows us to use hindsight in determining the lease term. We do not record an ROU asset and corresponding lease liability for leases with an initial term of 12 months or less (“short-term leases”). The terms in our leases may include options to extend or terminate the lease when it is reasonably certain that we will exercise those options. Judgment is required in our assessment as to whether renewal or termination options are reasonably certain to be exercised and factors such as contractual terms compared to current market rates, the importance of the facility and location to the Company’s operations, among others, are considered. Lease payments are made in accordance with the lease terms and lease expense, including short-term lease expense, is recognized on a straight-line basis over the lease term.

New Accounting Standards and Accounting Policy

2. New Accounting Standards and Accounting Policy

In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-04, “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” which simplified the testing of goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measured a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. ASU 2017-04 is effective for public companies for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. We are currently evaluating the effects that the adoption of ASU 2017-04 will have on our consolidated financial statements.

In February 2018, the FASB issued ASU No. 2018-02, “Income Statement — Reporting Comprehensive Income (Topic 220) — Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” ASU 2018-02 allows for a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the enactment of the U.S. Tax Cuts and Jobs Act (“the Act”). The update also requires entities to disclose whether or not they elected to reclassify the tax effects related to the Act as well as their accounting policy for releasing income tax effects from accumulated other comprehensive income. ASU 2018-02 is effective for financial statements issued for annual periods beginning after December 15, 2018, and interim periods within those annual periods, with early adoption permitted. We did not adopt the optional guidance of this accounting standard update as the potential impact on our consolidated financial statements is not material.

Adoption of New Lease Accounting Standard

In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASC 842”), which requires lessees to recognize right-of-use (“ROU”) assets and lease liabilities, initially measured at present value of the lease payments, on its balance sheet for leases and classified as either financing or operating leases. The new lease standard is effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We adopted ASC 842 on January 1, 2019, using the modified retrospective method, and we elected the package of practical expedients provided in ASC 842. In accordance with ASC 842, we did not restate comparative periods and instead reported comparative periods under ASC 840, “Leases.” We recorded operating lease ROU assets of $33.7 million as part of “Other assets” and corresponding lease obligations of $4.9 million and $32.3 million as part of “Accrued expenses and other current liabilities” and “Other long-term liabilities,” respectively, on our consolidated balance sheet upon adoption of ASC 842 on January 1, 2019. There was no material impact to our consolidated statement of operations and no cumulative effect adjustment to our retained earnings upon adoption of ASC 842. See Note 5 below for more information.

Lease Accounting Policy

ROU assets represent our right to use an underlying asset during the reasonably certain lease term and lease liabilities represent our obligation to make lease payments arising from the lease. We recognize ROU lease assets and lease liabilities at lease commencement on our consolidated balance sheet based on the present value of lease payments over the lease term using a discount rate determined based on our incremental borrowing rate since the rate implicit in each lease is not readily determinable. We elected the package of practical expedients, which permits us to not reassess (1) whether any expired or existing contracts are or contain leases, (2) the lease classification of any expired or existing leases, and (3) any initial direct costs for any existing leases as of the effective date. We elected the practical expedient to account for each separate lease component of a contract and its associated non-lease components as a single lease component.
