Green Co. constructed a machine at a total cost of $57.00 million. Construction was completed at the end of 2014 and the machine was placed in service at the beginning of 2015. 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 $3.00 million. At the beginning of 2018, Green decided to change to the straight-line method.

Required: 1. Ignoring income taxes, what journal entry(s) should Green record relating to the machine for 2018?

2. Suppose Green has been using the straight-line method and switches to the sum-of-the-years-digits method. Ignoring income taxes, what journal entry(s) should Green record relating to the machine for 2018?
