Each assumption is important, but should not be viewed in isolation.
It is the effect of the package of assumptions that is important.
Some of the assumptions are inter-related too. For example, high
levels of salary increase alone would increase costs substantially,
but may be accompanied by high investment returns and high interest
rates, which means relatively high annuity rates. These accompanying
factors would tend to reduce costs. Conversely, low inflation, low
investment returns and low maturity rates increase costs.
-
These assumptions will be reviewed regularly by the scheme actuary,
generally every three years.
-
Use of assumptions enable pensions to be funded in advance, and
there are a number of ways of approaching this:-
- Controlled funding, which enables an 'average' cost to be charged
for each scheme member, rather than the actual cost for accumulating
that member's projected benefit. In general, this reduces the costs
for the employer. It is only appropriate for group occupational
schemes, rather than individual account schemes like Executive Pension
Plans and Additional Voluntary Contributions.
- Deposit Administration, where contributions are invested to produce
a yield rather like a deposit account, and possibly bonuses similar
to a with profits contract.
- Deferred annuity basis, either guaranteed or with profits, providing
a guaranteed amount of future pension or a fixed contribution over
the period
