Can you help me with this problem?

Consumer Insurance, Inc. sells extended warranties on appliances that provide coverage after the manufacturers' warranties expire. An analyst for the company forecasts that the company will have to pay warranty claims of $5 million per year for three years, with the first costs expected to occur four years from today.
