Problem - Field Corp.'s controller was preparing the year-end adjusting entries for the company's year ended December 31, 2017, when the V.P. Finance called him into her office.

"Jean-Pierre," she said, "I've been considering a couple of matters that may require different treatment this year. First, the patent we acquired In early January 2015 for 5591,000 will now likely be used until the end of 2019 and then be sold for $179,000. We previously thought that we'd use it for 10 years In total and then be able to sell it for 5118,000. We've been using straight-line amortization on the patent."

"Second, I just discovered that the property we bought on July 2, 2014 for $267,200 was charged entirely to the Land account instead of being allocated between Land ($62,200) and Building ($205,000). The building should be of use to us for a total of 20 years. At that point, it'll be sold and we should be able to realize at least 547,000 from the sale of the building."

"Please let me know how these changes should be accounted for and what effect they will have on the financial statements."
