Answer:
This type of income is known as non-operating income in the financial statements
Step-by-step explanation:
Non-operating income, as the world implies, is the income that a firm earns from activities that are not related to its main economic activity. An example would be a mall, whose main activity is the rental and management of commercial real estate, earning some income from short-term investments in the secondary market. This interest would be reported as non-operating income, and would be treated as such for financial, accounting, and tax purposes.
