You review the energy consumption in your workplace and have found that the lighting system is not energy efficient enough. After looking at different solutions, you have come to the conclusion that an investment in motion sensors and low-energy lamps suits the company best. According to your calculations, the investment would mean savings of SEK 10,000 in the first year and thereafter the savings are expected to decrease by 2% per year. The size of the savings is calculated at the end of each year from installation and installation takes place immediately. How much is the company willing to pay for the lighting system today if it is assumed that its lifespan is 3 years and that the risk-free interest rate will be 5.54% the first year, 7.23% the second year and 6.70% the last the year? Round off your answer to the nearest integer.
