AMOUNT OF BENEFIT

  There are two distinct methods of ascertaining how much any given benefit should be. These are described as being defined benefits or money purchase benefits. Some schemes may provide a mixture of the two types of benefit but it is convenient to consider them separately. Both methods entail the involvement of actuaries.

1. Defined Benefits

  Here the benefits are fixed or more usually ascertainable. The calculations of benefits is usually by reference to salary to which a fraction (for example 1/100, 1/80, 1/60) for each year is applied. Usually it is applied to the final salary although some schemes apply to an average of career earnings.

  Somehow these benefits have to be funded. So long as the scheme is continuing, effectively the employer is bearing the cost and investment risk. What is required to fund the benefits is worked out by an actuary. He will work out the likelihood of how many people will leave service or die before retirement date and how much the benefits for them will cost and the likely time when those benefits will come into payment.

  Since the benefits are based on length of service and salary the actuary will have to make assumptions as to what those are likely to be. For example he will take current salaries and make assumptions about salary inflation. He will also have to allow for people being promoted to better paid positions but over the average of any reasonably sized scheme the seniority distribution of people is likely to remain about the same. He also has to make assumptions about when these benefits will come into payment and that involves assumptions about how long people will serve. Finally, he needs to make assumptions about what annuity rates will be available to purchase pension at the time. These are all based on complex formulae which are largely related to yields on long-term gilts.

  That enables the actuary to work out what is likely to need to be invested and when. He then has to work back to determine what has to be put in now and over the period in order to achieve that sum and to spread that evenly over a period of years. In doing that of course the funds are invested and therefore he has to make assumptions about investment yields on that money between being put in and being eventually needed. Indeed he has to make assumptions about the return on the initial investment and also what is known as the re-investment rate for the re-investment of the income on the original investment. The Pensions Act 1995 requires trustees of a pension scheme to meet the minimum funding requirement and to have schedules of contributions for that purpose. This helps to reduce over-creative use of assumptions.

  Having worked out what the necessary contributions are these are then expressed as a percentage of salaries and that percentage rate is known as the funding rate. At any given time that funding rate may produce a surplus or a deficit. No-one can know exactly, and the surplus or deficit may vary depending upon what assumptions are used. Assumptions are therefore very critical. If the assumptions are wrong, the whole thing is wrong. Assumptions are vitally important, particularly in final salary schemes. By seemingly minor adjustments of a fraction of a percent, millions of pounds can appear or disappear. With assumptions to be made about salary inflation, general inflation, investment rates, re-investment rates etc., scope for statistical prestidigitation is very wide indeed. When you receive an actuarial report almost certainly the assumptions will be the vital part. Over the life of a scheme variations and or errors in assumptions can be evened out. When pension rights are to be valued, future income is being capitalised now and the assumptions must be right.

  They can also be paid to a separate individual arrangement known as a free standing additional voluntary contribution scheme, which is a bit like a personal pension.

2. Money purchase

  In a pure money purchase scheme there is no promise as to the amount of the benefits which will be received. Usually there is a fixed rate of contributions from employer and employee and whatever these build up will be the amount to be applied to the benefits at the end of the day. Some of the contributions may be applied to life assurance benefits. The investment risk is with the members, not the employer who is not underwriting a global fund.

  Some money purchase schemes do not even have a prescribed contribution rate. They are purely discretionary. They are sometimes known as "top-hat" schemes.

  Eventually an actuary works out what benefits the accumulated sum will buy.

  For a variety of reasons (including perceived cost control, escaping the full rigours of the Pensions Act) these have increased greatly recently and you will encounter them more.

3. Additional Voluntary Contributions

  Under the Pension Schemes Act 1993 a member has a statutory right to pay additional voluntary contributions. They usually provide money purchase benefits, going into a separate fund. The separate fund can mean they are forgotten about when benefits are being quoted.
