Theory of interest rates

  • Interest and discount rates, and rate conversions

  • Simple and compound interest, discounting a single payment

  • Force of interest varying with time

  • Real and money rates: allowing for inflation

  • Cashflow models of financial instruments and insurance contracts

  • Level annuities and accumulations: annual, pthly and continuous

  • Deferred, increasing and varying annuities

  • Present and accumulated values of general cashflow streams

Term structure, duration and immunisation

  • Term structure of interest rates and its determinants

  • Spot rates and forward rates, discrete and continuous

  • Par yield and yield to maturity

  • Duration and convexity of a cashflow sequence

  • Redington's conditions and immunisation of liabilities

Equation of value and its applications

  • The equation of value: certain and uncertain payments

  • Loan schedules, capital and interest components, APR

  • Bond pricing and yields with income tax and capital gains tax

  • Running yield, redemption yield and index-linked bonds

  • Optional redemption dates: bounds on present value

  • Valuing ordinary shares and property with growing income

  • Project appraisal: NPV, IRR and payback periods

Life contingencies: contracts and life tables

  • Assurance and annuity contract types and their cashflows

  • With-profits, unit-linked and accumulating with-profits contracts

  • Life table functions and select mortality

  • Survival and death probabilities, deferred and select forms

  • Assurance and annuity factors, including continuous and pthly forms

  • Relationships between assurance and annuity functions

Means, variances and multiple life functions

  • Expected present value and variance of benefit payments

  • Premium and benefit payment patterns in EPV formulae

  • Expected accumulations under assurance and annuity contracts

  • Joint life and last survivor functions

  • Two-life functions dependent on a fixed term as well as age

Multiple state and multiple decrement models

  • Multiple-state Markov models: forces and probabilities of transition

  • Health insurance premium and benefit structures

  • EPVs of cashflows contingent on multiple transitions

  • Multiple decrement tables and their construction

  • Dependent probabilities and forces of transition

Premiums and reserves

  • The gross future loss random variable

  • Gross premiums by the equivalence principle, with expenses

  • Prospective and retrospective reserves and their equivalence

  • Recursive relationships between successive reserves

  • Net premiums and net premium valuation

  • Death strain at risk and mortality profit

Profit testing and cashflow projection

  • Projecting expected cashflows with multiple decrements

  • Profit vector, profit signature, NPV and profit margin

  • Using a profit test to price a contract

  • Unit-linked contracts: unit and non-unit fund projections

  • Zeroising negative cashflows with non-unit reserves

  • Reserves within a profit test and their effect on profit
