Paramount Corporation acquired its 75 percent investment in Sun Corporation in January 2012, for $5,820,000 and accounts for its investment internally using the complete equity method. At the acquisition date, total book value of Sun was $3,000,000 including $1,600,000 of retained earnings, and the estimated fair value of the 25 percent noncontrolling interest was $1,580,000. The fair values of Sun's assets and liabilities were equal to their carrying values, except for the following items: Fair value less Book value
Accounts receivable $(200,000)
Inventory (250,000)
Equipment (10 years, straight-line) (800,000)
Patents (5 years, straight-line) 400,000
Deferred tax liabilities (created as a result of the nontaxable acquisition) 150,000

The receivables were collected and the inventory sold during the first three years following the acquisition. Deferred tax liabilities of $120,000 were reversed during 2012–2017. An impairment test made at the end of 2017 indicates a remaining value of $4,000,000 for the goodwill recognized as a result of the acquisition. Sun's shareholders' equity is $5,000,000 including $3,600,000 of retained earnings, at the end of 2017.
