Both of these investments were acquired when book value was equal to fair value of identifiable net assets acquired. Both of these investments were accounted using the initial value method.

Separate net income totals for 2017, not including investment income for any company, were as follows: Mace Co. $ 420,000 Lance Co. 224,000 Curle Co. 168,000 Following are the 2018 financial statements for these three companies.

In each of these years, Lance held 20% of the inventory it bought from Curle and then sold that inventory to outsiders in the following year. An effective income tax rate of 45% was applicable to all companies. Mace Co. Lance Co. Curle Co.
