Percy Byron, CFA, is an equity analyst with a UK-based investment firm. One firm Byron follows is NinMount PLC, a UK-based company. On 31 December 2018, NinMount paid ￡320 million to purchase a 50 percent stake in Boswell Company. The excess of the purchase price over the fair value of Boswell's net assets was attributable to previously unrecorded licenses. These licenses were estimated to have an economic life of six years. The fair value of Boswell's assets and liabilities other than licenses was equal to their recorded book values. NinMount and Boswell both use the pound sterling as their reporting currency and prepare their financial statements in accordance with IFRS.Byron is concerned whether the investment should affect his “buy” rating on NinMount common stock. He knows NinMount could choose one of several accounting methods to report the results of its investment, but NinMount has not announced which method it will use. Byron forecasts that both companies' 2019 financial results (excluding any merger accounting adjustments) will be identical to those of 2018.NinMount's and Boswell's condensed income statements for the year ended 31 December 2018, and condensed balance sheets at 31 December 2018, are presented in Exhibits 1 and 2, respectively.
