Below are four independent, material and unrelated situations involving accounting changes. Each change occurs during 2020 before any adjusting or closing entries were prepared. Assume a tax rate of 40% and any tax effects are adjusted through the deferred tax asset or liability account.

Discuss and evaluate the type of accounting change, briefly describe any steps that should be taken to appropriately report the situation and complete journal entries to document the change

a. On December 31, 2011, Kevin Inc. acquired its office building at a cost of $8,000,000. It has been depreciated on a straight-line basis assuming a useful life of 40 years and no salvage value.
