|Goodwill and Intangible Assets Disclosure [Abstract]|
Note 7: Goodwill
Goodwill is not amortized, rather it is evaluated for impairment on July 1 annually or when indicators of a potential impairment are present. The annual evaluation for impairment of goodwill is based on valuation models that incorporate assumptions and internal projections of expected future cash flows and operating plans. We believe such assumptions are also comparable to those that would be used by other marketplace participants. There was no goodwill impairment during fiscal 2018.
The entire disclosure for goodwill.
