Change in inventory methods
Response to the following problem:
Irwin, Inc., constructed a machine at a total cost of $35 million. Construction was completed at the end of 2012 and the machine was placed in service at the beginning of 2013. The machine was being depreciated over a 10-year life using the sum-of-the-years'-digits method. The residual value is expected to be $2 million. At the beginning of 2016, Irwin decided to change to the straight-line method.
Ignoring income taxes, what journal entry(s) should Irwin record relating to the machine for 2016?
