If I keep the policy for another five years, the estimated cash value increases to $62,417, giving a yield of 3.9% for the next 5 years, based on the projected bonus for the next 5 years. I have decided not to take the risk of a further reduction in bonus, which will reduce the yield below 3.9%.
By surrendering the policy, I can invest the money in other investments. As the share prices are quite low, there is a good chance of earning a better high rate of return from other investments.
