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

Decrement and multiple life models

    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

    Pricing and reserving

      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
