Final answer:
A tune-up of a company vehicle (option B) is not a capital expenditure as it is considered revenue expenditure, while the other options present investments in long-term assets and are thus capital expenditures.
Step-by-step explanation:
Among the options presented, the one that is not a capital expenditure is B) A tune-up of a company vehicle. Capital expenditures (CAPEX) are investments in assets that will provide benefit over a long period of time. They usually involve significant sums of money and include costs related to the acquisition or improvement of long-term assets such as equipment, buildings, and vehicles.
On the other hand, a tune-up is considered a revenue expenditure, as it pertains to the regular maintenance required to keep assets in working condition and does not extend the life or enhance the value of the asset in a way that would classify it as a capital expenditure. Some points to be noted regarding investment expenditure include spending on new durable equipment and software, nonresidential and residential structures, and changes in inventories. Firms typically invest in such assets during times of economic growth to increase capacity and facilitate future profit generation.
