Regular Corp. has four divisions. One of them, Weeble Products, was acquired on January 1, 2016, for $60,000,000, and recorded goodwill of $6,000,000 as a result of that purchase. At December 31, 2017, Weeble Products had a fair value (including goodwill) of $37,000,000. and the book value of the company's net assets (without goodwill) was $44,000,000. The fair value of Weeble's net assets (without goodwill) at December 31, 2017 was $33,000,000. What amount of loss on impairment of goodwill should Regular record in 2017?

The answer is $2,000,000. I want to know how to calculate.
