RE: Pension deficit29 Oct 2020 13:20
This mightn’t help but basically the objective is to match cash flows and ‘immunise’ the investment portfolio against inflation. So in year 28 for example the cash from investments - through dividends, coupons and redemptions - match the payouts from the plan as closely as possible. This works best with government bonds because when inflation increases the value of the bonds decrease but so does the pension liability. And vice versa. It is ‘immunised’. Importantly the assumption here is that the gov bond is risk free and the shape of the yield curve stays the same.
But with the property, corporate debt, equities - there is more to it than inflation because default risk or corporate risk is also a factor. This will have risen. So although some of the corporate debt will be worth more because yields have decreased, the rise won’t be enough to offset the rise in liabilities which will have occurred similarly from lower interest rates.
This fake example may help;
Before Covid:
Liability - 100
Assets - 100
Deficit - 0
Interest rates - 10%
Risk of default - 5%
Now
Liability - 200
Assets - 195
Deficit - 5
Interest rates - 5%
Risk of default -10%
The halving of interest rates doubles the value of the assets and liabilities all else being equal...but it’s not all equal sadly cause the cash flows of those assets are now riskier given corporate profits, commercial property tanking etc etc.
Sorry if that’s not very clear.
I don’t think the pension deficit is anywhere near as important as headcount going down by 5% or churn being low or OFCOMs review fwiw
