At the date of acquisition of the stock, Devon's total net assets had a fair value of $3,500,000 and a book value of $3,100,000. The undervalued assets have a remaining useful life of 5 years. Assume Devon, Inc. earned $100,000 and paid $50,000 of dividends. All of the goodwill was related to a Patent that was worthless at the end of the year. How much would Manav write off to Equity Method Investments because of the worthless Patent?
