Goodwill, impaired, method for fair value determination |
the television reporting unit fair value exceeded its carrying value by 48%, resulting in no impairment charge in 2018. The discount rate used in the fair value calculation of the television reporting unit was increased from prior year and expected cash flows of a component of the reporting unit were decreased from prior year to account for risk within the forecasts of the reporting unit. If that discount rate were to increase by 1%, the fair value of the television reporting unit would decrease by 6%. If the long term projected growth rate were to decrease by 0.5%, the fair value of the television reporting unit would decrease by 1%.
