The Greenriver Manufacturing Company manufactures two products: Raft and Float. At December 31, 2014, Greenriver used the FIFO inventory method. Effective January 1, 2015, Greenriver changed to the LIFO inventory method. The retroactive effect of this change is not determinable, and as a result, the ending inventory for 2014 for which the FIFO method was used is also the beginning inventory for 2015 for the LIFO method. Any layers added during 2015 should be costed by reference to the first acquisitions of 2015. The information below was available from Greenriver inventory records for the two most recent years: Compute the effect on net income for the year ended December 31, 2015, resulting from the change from the FIFO to the LIFO inventory method.
