On July 1, 2016, Killearn Company acquired 88,000 of the outstanding shares of Shaun Company for $13 per share. This acquisition gave Killearn a 25 percent ownership of Shaun and allowed Killearn to significantly influence the investee's decisions. As of July 1, 2016, the investee had assets with a book value of $3 million and liabilities of $74,400. At the time, Shaun held equipment appraised at $364,000 above book value; it was considered to have a seven-year remaining life with no salvage value. Shaun also held a copyright with a five-year remaining life on its books that was undervalued by $972,000. Any remaining excess cost was attributable to goodwill. Depreciation and amortization are computed using the straight-line method. Killearn applies the equity method for its investment in Shaun.

Shaun's policy is to declare and pay a $1 per share cash dividend every April 1 and October 1. Shaun's income, earned evenly throughout each year, was $598,000 in 2016, $639,600 in 2017, and $692,400 in 2018.
