# F70LB Life Insurance Mathematics B

Course co-ordinator(s): Dr Larry O’Brien (Malaysia), Ian Sharpe (Edinburgh).

Aims:

This course aims:

• to introduce some more advanced topics in life insurance mathematics, and complete the material covered in Subject CT5

Summary:

• Thiele’s differential equation
• Markov multiple-state models
• risk reserves
• insurances written on multiple lives
• the features of disability and long-term care insurance and pension contracts
• heterogeneity and selection
• single-figure indices
• profit testing conventional insurance contracts

Pre-requisite course(s): F70LA Life Insurance Mathematics A .

Location: Edinburgh, Malaysia.

Semester: 2.

Learning Outcomes: Subject Mastery

At the end of studying this course the students should be able to do or understand the following:

• derive Thiele’s differential equation for standard insurance benefits, and solve it numerically using an Euler scheme
• define Markov life-history models in terms of states, transitions and transition intensities
• state and prove Kolmogorov’s forward equations, state Thiele’s differential equations, and use an Euler scheme to solve both numerically, for a general Markov multiple-state model
• calculate risk reserves for simple homogeneous life insurance portfolios
• define models for the joint life histories of two individuals; (a) as a multiple-state model; and (b) in terms of random future lifetimes
• calculate expected present values, premiums and policy values for the following types of joint-life policies: first-death and second-death assurances and annuities, reversionary annuities, and contingent assurances
• describe the main features of disability insurance, long-term care insurance and defined-benefit pension schemes
• understand possible sources of heterogeneity, its effect on the analysis of insurance data, and its possible impact on insurance business
• construct single figure indices to summarise mortality and other experiences, and understand the strengths and weakness of each
• calculate the profit vector, profit signature, net present value, profit margin, discounted payback period, and internal rate of return for conventional policies
• describe the effect on the profit vector of changes in the premium, valuation, and experience bases
• describe the operation of the unit price and the charging structure for unit-linked policies
• calculate the unit fund, sterling fund, sterling reserve, and measures of profit for unit-linked policies

• Formulae and Tables for Actuarial Examinations
• Introduction to Survival Models, Volumes 2 and 3 Hardy, Macdonald, Waters and McCutcheon.
