MATH 472/567: Actuarial Theory II/Topics in Actuarial Theory I Homework #3: Spring 2011 Assigned February 2, due February 9 1. Suppose: (i) Mortality follows the Illustrative Life Table. (ii) i = 0.06 (iii) Deaths are uniformly distributed within each year of age. Calculate: 5000 9 . 3 V 1 45: 20 . (189.67) 2. Re-do Problem 1, except calculate: 5000 9 . 3 V (12) 1 45: 20 . You may use anything that you calculated in Problem 1 along with the α ( m ), β ( m ) handout. (164.83) 3. (a) Using the following formula for h + s V for h = 0, 1, . .. and 0 < s < 1: h + s V = v 1 - s b h +1 × 1 - s q x + h + s + v 1 - s h +1 V × 1 - s p x + h + s , show that assuming a constant force of mortality between integer ages (refer to Table 3.6.1 of the text) results in h + s V equaling: v 1 - s [ b h +1 - p 1 - s x + h ( b h +1 - h +1 V )]. (b) Now consider a general fully discrete life insurance on (x), where: (i) The death benefit for the 11th year is 10. (ii) The terminal benefit reserve for the 11th year is 43. (iii) δ = 0.06 (iv) q x +10 = 0.10 Calculate the benefit reserve at time 10.5 assuming a constant force of mortality between integer ages. (40.09) ————THERE ARE MORE PROBLEMS ON THE BACK ————

Unformatted text preview: 1 4. Consider a fully discrete 5-year endowment insurance of 5000 on (40): (i) The annual level benefit premium is 843.07. (ii) Mortality follows the Illustrative Life Table. (iii) i = 0.06. Calculate: var [ 3 L | K (40) = 3 , 4 ,... ]. (3872.01) 5. For a fully discrete 3-year term insurance of 1000 on (x) with annual level benefit premiums: (i) i = 0.10 (ii) The mortality rates and terminal benefit reserves are given by: h q x + h h +1 V 0.3 95.833 1 0.4 120.833 2 0.5 (a) Determine the annual level benefit premium. (333.71) (b) Calculate L assuming (x) dies: (1) in the first year, (2) in the second year, (3) in the third year, and (4) after the third year. (575.38, 189.36, -161.57,-912.88) (c) Calculate var [ L ] using: (1) var [ L ] = E [ L 2 ]-E [ L ] 2 and (2) the Hattendorf Theorem. Round your final answers to the nearest integer. (289,844) 2...
