Accounting Policies [Abstract]
Recent Accounting Developments	In February 2016, the Financial Accounting Standards Board (the "FASB") issued new lease accounting guidance, ASU 2016-02, Leases (also referred to as Topic 842), which we adopted on January 1, 2019. Under Topic 842, at the commencement date, lessees are required (a) to recognize a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis, and (b) to record a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842), Targeted Improvements, which gave companies the option of applying the new standard at the adoption date, rather than retrospectively to the earliest period presented in the financial statements, with recognition of a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. We chose the option to apply the new standard at the adoption date, and therefore we were not required to restate the financial statements for prior periods, nor are we required to provide the disclosures required by Topic 842 for prior periods. Upon adoption of Topic 842, we recognized an approximate $2.6 million right-of-use asset, and an approximate $3.2 million lease liability. Our previously recognized liability for lease incentives recorded under prior accounting standards was eliminated. The cumulative-effect adjustment to the opening balance of retained earnings related to our adoption of Topic 842 was inconsequential. Our adoption of Topic 842 did not impact our cash flows or have a material impact on our results of operations. We have expanded our consolidated financial statement disclosures to comply with the requirements of Topic 842. In February 2018, the FASB issued ASU 2018-02, Reclassification of Tax Effects from Accumulated Other Comprehensive Income ("ASU 2018-02"), which allows an entity to elect an option to reclassify the stranded tax effects related to the application of the Tax Cuts and Jobs Act (the "TCJA") from accumulated other comprehensive income or loss to retained earnings. ASU 2018-02 was effective January 1, 2019 and could be applied either in the period of adoption or retrospectively to all applicable periods. We did not elect to reclassify the stranded tax effects related to the application of the TCJA from accumulated other comprehensive loss to retained earnings. In January 2017, the FASB issued guidance on simplifying the test for goodwill impairment, ASU 2017-04, Simplifying the Test for Goodwill Impairment ("ASU 2017-04"). Under ASU 2017-04, goodwill impairment would be measured as the amount by which a reporting unit’s carrying value exceeds its fair value, but not in an amount in excess of the carrying value of goodwill. The new standard eliminates the requirement to determine goodwill impairment by calculating the implied fair value of goodwill by hypothetically assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. ASU 2017-04 is to be applied prospectively to impairment tests beginning January 1, 2020, with early adoption permitted. We are currently evaluating when we will adopt ASU 2017-04 and do not expect the adoption to have a material impact on our consolidated financial statements.
