Goodwill is allocated to each identified reporting unit, which is defined as an operating segment or one level below the operating segment (referred to as a component of the entity). Management has determined that the Company’s hospital operations segment meets the criteria to be classified as a single reporting unit. At September 30, 2017, the Company had approximately $6.1 billion of goodwill recorded, all of which resides at its hospital operations reporting unit.

Goodwill is evaluated for impairment at the same time every year and when an event occurs or circumstances change that, more likely than not, reduce the fair value of the reporting unit below its carrying value. There is a two-step method for determining goodwill impairment. Step one is to compare the fair value of the reporting unit with the unit’s carrying amount, including goodwill. If this test indicates the fair value is less than the carrying value, then step two is required to compare the implied fair value of the reporting unit’s goodwill utilizing a hypothetical purchase price allocation with the carrying value of the reporting unit’s goodwill. The Company performed its last annual goodwill evaluation during the fourth quarter of 2016. No impairment was indicated by this evaluation. The next annual goodwill evaluation will be performed during the fourth quarter of 2017, or sooner if the Company identifies certain indicators of impairment.

While no impairment was indicated by the fourth quarter of 2016 evaluation, the reduction in the Company’s fair value and the resulting goodwill impairment charge recorded during 2016 reduced the excess of fair value calculated in the step two analysis over the carrying value of the Company’s hospital operations reporting unit to an amount less than 1% of the Company’s carrying value. This minimal amount in the excess fair value over carrying value of the hospital operations reporting unit increases the risk that future declines in fair value could result in goodwill impairment. The determination of fair value in the Company’s goodwill impairment analysis is based on an estimate of fair value for each reporting unit utilizing known and estimated inputs at the evaluation date. Some of those inputs include, but are not limited to, the most recent price of the Company’s common stock or fair value of long-term debt, estimates of future revenue and expense growth, estimated market multiples, expected capital expenditures, income tax rates, and costs of invested capital. Future estimates of fair value could be adversely affected if the actual outcome of one or more of these assumptions changes materially in the future, including further decline in the Company’s stock price or fair value of long-term debt, lower than expected hospital volumes, or increased operating costs. Such changes impacting the calculation of fair value could result in a material impairment charge in the future.

The Company estimates the fair value of the related reporting units using both a discounted cash flow model as well as a market multiple model. The cash flow forecasts are adjusted by an appropriate discount rate based on the Company’s estimate of a market participant’s weighted-average cost of capital. These models are both based on the Company’s best estimate of future revenues and operating costs and are reconciled to the Company’s consolidated market capitalization, with consideration of the amount a potential acquirer would be required to pay, in the form of a control premium, in order to gain sufficient ownership to set policies, direct operations and control management decisions.
