There are many differnet sources from which individuals can derive a pension income
We are mainly concerned with company pension plans in this section
Fundamentally company pensions divide into two different types:
There can also be all kinds of mixed and hybrid systems
Typically occupationl pension schemes are funded as the benefits accrue
Some schemes (notably the UK state pension scheme) is unfunded and benefits are paid from taxation and national insurance contributions as they are paid
DC schemes are often effectively terminally funded as the pension pot builds up over a lifetime and then buys an annuity in one lump sum at retirement
In the main actuaries work out how much money you need to invest as benefits accrue in occupational pension schemes to pay the benefits as they fall due.
So we mainly deal with Defined Benefit, Occupational Schemes
This is what this chapter is about
What Benefits do they provide
In the coursework you will perform a full pension scheme valuation
When your coursework is complete you will be able to test the impact on scheme funding of different types of benefit.
You will also be able to consider how much risk each type of benefit exposes the pension scheme funding to.
Try the following exercises:
To save money the company decides to halve the death in service benefit to 2 times salary. Assess how much this reduces the cost of the scheme.
Given that most members will also receive a basic state pension, the company decides to reduce the salary for pensionable service by £8,000 per member. Calculate how much money this will save the scheme.
To save money and encourage workers to stay in the firm for longer the company decides to increase the normal retirement age from 65 to 68. Assess how much money this saves.
In order to make the company more attractive as an employer - it decides to offer spouse's pensions for employee's who have died. Assess the cost of this for death in service and also for death of pensioners and deferreds.
You are a medium sized employer in the UK and you wish to improve your pension scheme to try and attract and retain key staff. However you have quite a limited budget which which to fund additional benefits. Discuss the type of changes you may make and give indicative costs of these changes.
You currently sponsor a UK pension scheme and for legacy reasons there is a spouse's pension for male employees but not for female employees. Equality legislation requires you to change this so that both male and female employees are treated the same. Discuss the financial and practical implications.
You are building a Monte Carlo MDM model for a pension scheme and for a given year the forces of decrement are 0.1% for death, 3% for early retirement and 10% for leaving to deferred. The first three numbers that your random number generator produces from the $U[0,1]$ distribution are 0.4,0.01 and 0.1. Calculate what decrement happens and when.
