Described below are three independent and unrelated situations involving accounting changes. Each change occurs during $2024$ before any adjusting entries or closing entries are prepared.

On December $30,2020,$ Rival Industries acquired its office building at a cost of $$10,000,000.$ It has been depreciated on a straight$-$line basis, assuming a useful life of $40$ years and no residual value. Early in $2024,$ the estimate of useful life was revised to $28$ years in total with no change in residual value.

At the beginning of $2020,$ the Hoffman Group purchased office equipment at a cost of $$330,000.$ Its useful life was estimated to be $10$ years with no residual value. The equipment has been depreciated by the straight$-$line method. On January $1,2024,$ the company changed to the double$-$declining$-$balance method.

At the beginning of $2024,$ Jantzen Specialties, which uses the straight$-$line method, changed to the double$-$declining$-$balance method for newly acquired vehicles. The change decreased current year net income by $$445,000.$
