Belltone Company made the following expenditures related to its 10-year-old manufacturing facility:

1. The heating system was replaced at a cost of $235,000. The cost of the old system was not known. The company accounts for improvements as reductions of accumulated depreciation.
2. A new wing was added at a cost of $840,000. The new wing substantially increases the productive capacity of the plant.
3. Annual building maintenance was performed at a cost of $21,500.
4. All of the equipment on the assembly line in the plant was rearranged at a cost of $54,000. The rearrangement clearly increases the productive capacity of the plant.
