In general, goodwill is not amortized per SFAS 142. There is a provision whereby goodwill must be tested for impairment each year and an adjustment will be made if goodwill has been impaired. There is an option for private companies to amortize goodwill over 10 years to avoid the hassle of impairment testing. For more info see: https://www.accountingcoach.com/blog/amortize-goodwill
