IAI Actuarial Core Principles · Actuarial Mathematics for Modelling · Gross random future loss

A whole life policy was issued at age x with sum assured Rs 200,000 and level annual premium Rs 2,500 payable in advance. Some years later the life, now aged x+t, is still alive. Valuation values are A_x = 0.45, A_{x+t} = 0.50 and ä_{x+t} = 13.0. What is the expected future loss at that time, given survival?

The expected future loss is Rs 67,500. At duration t the benefit value uses age x+t: 200,000 × 0.50 = 100,000, less the premium value 2,500 × 13.0 = 32,500. The issue-age assurance value of 0.45 must not be used.

Explanation

The future loss at duration t must use the values at age x+t. E[Lt] = 200,000 × 0.50 - 2,500 × 13.0 = 100,000 - 32,500 = 67,500. Using A_x = 0.45 gives 57,500, which is the wrong age. Using ä - 1 gives 70,000, which wrongly drops the premium due now.
