Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Goodwill Goodwill represents the premium paid for acquired companies above the fair value of the assets acquired and liabilities assumed, including separately identifiable intangible assets. At March 31, 2020 and December 31, 2019, the net carrying value of goodwill was $327 million. Goodwill is not amortized but is assessed for impairment on an annual basis, or more often if events or circumstances indicate there may be impairment, referred to as a triggering event. Upon the occurrence of a triggering event, accounting guidance allows for an assessment of qualitative factors to determine whether it is more likely than not, or a greater than 50% likelihood, that the fair value of the entity is less than its carrying amount, including goodwill. When it is more likely than not that impairment has occurred, management is required to perform a quantitative analysis and, if necessary, adjust the carrying amount of goodwill by recording a goodwill impairment loss. During the first quarter of 2020, as a result of market concerns about the potential impact of COVID-19, United’s stock price declined such that it traded below book value for the latter part of the quarter. As a result of this triggering event, management has qualitatively assessed and concluded that there is not a greater than 50% likelihood that United’s fair value is less than its carrying amount as of March 31, 2020, given the short duration of change in macroeconomic conditions and excess of value as of the latest annual test performed as of September 30, 2019. Management will continue to monitor and assess the impact of the pandemic on the Company’s value.
