Some example of Capital Expenditures include new production equipment for a manufacturing company, a new commercial HVAC system in an office building, and the purchase of a neighboring warehouse. These are all examples of Capital Expenditures because as these assets have real value, plus are expected to last more than a year.
New assets purchased by a company are not always considered a Capital Expenditure. For example, building maintenance supplies and parts for an entire office building might also have a significant cost, but these supplies do not usually benefit the company for more than a year, and would be expected to record these expenses as maintenance expense.
