Final answer:
Advertising, administrative salaries, sale commissions, insurance, and interest are examples of operating expenses, which are costs incurred in the day-to-day operations of a business, including an insurance company.
Step-by-step explanation:
Advertising, administrative salaries, sale commissions, insurance, and interest are all examples of operating expenses. Operating expenses are the costs associated with running a business day-to-day. They include everything from advertising to draw in customers, to administrative costs such as salaries for office staff, to sales commissions paid to incentivize salespeople. These costs also factor in insurance premiums to protect the business, as well as interest payments on any loans the company may have. In the context of an insurance company, operating expenses would be the costs involved in administering accounts and processing insurance claims, on top of the payment of claims themselves. These expenses are key considerations for insurance companies, as the insurance premiums coming in and claims payments going out typically overshadow the funds earned by investing money or managing administrative costs.
