For those people who are not pensions geeks, let me start by explaining what the Pension Protection Fund (PPF) is. Brought in by the Pensions Act 2004 in response to several examples of people getting to retirement and finding little or no funds left in their defined benefit (DB) pension schemes to pay them benefits, it is a quasi autonomous non-governmental (allegedly) organisation (QUANGO) charged with accepting pension schemes who have lost their sponsors and don’t have enough money to buy at least PPF level benefits from an insurance company. It is, as the PPF themselves appear to have acknowledged with several references to the schemes not yet in their clutches as the “insured” in a talk I attended last week, a statutory insurance scheme for defined benefit occupational pension schemes, paid for by statutory levies on those insured. As a scheme actuary I have always been very glad that it exists.

The number of insured schemes has dwindled since it was named the 7800 index in 2007 (with not quite 7,800 members at the time) to the 6,300 left standing today. As you can imagine, the ever smaller number of schemes whose levies are keeping the PPF ship afloat are very nervous about how that cost is going to vary in the future. They have seen how volatile the funding of their own schemes is, and seemingly always in the worst case direction, and worry that, when their numbers get small enough, funding the variations in PPF deficits could become overwhelming. Particularly as the current Government says whenever it is asked (although no one completely believes it) they will never ever bail out the PPF.

So there has been keen interest in the PPF explanations of how those levies are going to change next year.

PPF levies are in two parts. The scheme-based levy, which is a flat rate levy based on the liability of a scheme, and the normally-much-bigger-as-it-has-to-raise-around-90%-of-the-total-and-some-schemes-don’t-pay-it-if-they-are-well-funded-enough risk-based levy. The risk-based levy depends on how well funded you are, how risky your investment strategy is and the risk your sponsor will become insolvent over the next 12 months.

It is this last one, the insolvency risk, which is about to change. Dun and Bradstreet have lost the contract to work out these insolvency probabilities after eight years in favour of Experian. However, unfortunately and for reasons not divulged, the PPF has struggled to finalise exactly what they want Experian to do.

The choices are fairly fundamental:

• The model used. This will either be something called commercial Delphi (similar to the approach D&B currently use) or a more PPF-specific version which takes account of how different companies which run DB schemes are from companies which don’t. The PPF-specific version looks like it was originally the front runner but has taken longer to develop than expected.

• The number of risk levels. Currently there are 10, ie there are 10 different probabilities of insolvency you can have based on the average risk of the bucket you have landed in. One possibility still being considered at this late stage is not grouping schemes at all and basing the probability on what falls out of the as yet to be announced risk model directly. This could result in considerable uncertainty about the eventual levy. Even currently, being in bucket 10 means a levy 22 times bigger than being in bucket 1.

So reason for nervousness amongst the 6,300 perhaps? The delay will mean that it won’t be known by 1 April (an appropriate date perhaps) when data starts to be collected for the first levies under the new system next year. Insolvency risk is supposed to be based on the average insolvency probability over the 12 months to the following March, but the PPF will either have to average over a smaller number of months now or go back and adjust the “failure scores” (as the scale numbers which allocate you to a bucket are endearingly called) to the new system at a later date. Again, the decision has yet to be made.

All of this suggests an organisation where making models is much easier than making decisions. And that is in no one’s interest.

Perhaps surprisingly in the audience I was in, the greatest concern expressed was about the fact that the model the PPF uses to assess the overall risk to their future funding (and therefore used to set the total levy they are trying to collect each year) was different from either the current D&B approach, or either of the two possible future approaches, to setting failure scores, ie the levies they pay are not really based on the risk they pose to the PPF at all.

There are obviously reasons why this should be the case. Many of the risk factors to the PPF’s funding as a whole would be hard to attribute, and therefore charge, to individual sponsors. For instance the PPF’s Long-Term Risk Model runs 1,000 different economic scenarios (leading to 500,000 different scenarios in total) to assess the amount of levy required to ensure at least an 80% chance of the PPF meeting its funding objective of no longer needing levies by 2030. Plus it plays to sponsors’ basic sense of fairness that things like their credit history and items in their accounts (although perhaps not including, as now, the number of directors) should affect where they stand on the insolvency scale, rather than things that would impact more on PPF funding, like the robustness of their scheme deficit recovery plans for instance.

It is rather like the no claims discount system for car insurance. This has been shown to be an inefficient method for reallocating premiums to where the risk lies in the car driving population, and this fact has been a standard exam question staple for actuarial students for many years. However it is widely seen as fair by that car driving population and would therefore be commercial madness for any insurer to abandon.

So there we have it. The new PPF levy system. Late. Not allocating levies in accordance with risk. And coming to a pension scheme near you soon.
