Medical Schemes, discrimination and the CPA

Posted on by

The Consumer Protection Act (CPA) protects consumers from abuse by enforcing fair practices, improved disclosure and added minimum warranties etc,

It’s a good piece of legislation, even if at times some aspects of it may result in greater costs than benefits.

TimesLive has a story about the alleged noncompliance of medical schemes with the CPA.

Some of the issues may have merit, but this struck me as particularly troubling:

According to the act, it is unfair when a consumer is discriminated against on the grounds of age.

Our constitution explicitly allows discrimination on actuarially sound rating factors that have both a statistical and causal link. This is how insurance is South Africa still uses underwriting to select homogenous groups of risks and to limit anti-selection by policyholders. If widespread anti-selection were to occur, then life insurance would not be viable.

Medical Schemes in South Africa have only very limited underwriting options in order to provide as many citizens as possible with fair health coverage. “Late joiners” are charged a premium since they haven’t contributed to the societal risk pool since they were most healthy and therefore haven’t paid “their fair share”. This has to do with a specifically identified risk rather than general discrimination based on age. These restrictions are important to maintain the solvency and viability of medical schemes.

Some schemes prevent women who fall pregnant within nine months of joining the scheme from claiming for the pregnancy even though they pay full premiums

This point is more tricky, but it does again reflect a misunderstanding. “Full premiums” on an actuarial sound basis have probably not been paid, since the fair premium for a member who joins just to get pregnancy benefits and hasn’t contributed at other times would be much higher than the premium that is charged. This one is a little more grey and while I feel the rules are entirely fair, they may not be viewed that way by a particular judge on a particular day.

Some schemes require that members give three months’ notice when terminating their membership, whereas the act deems 20 business days to be reasonable

This might reflect the desire to not have members leave a scheme immediately after having utilized the maximum benefit available to them before joining another scheme. I don’t know how much of this behavior would ever happen, so this might also ultimately be changed.

Many schemes don’t enforce the allowed waiting periods for members joining. If some of these other changes were to be made, I would expect these provisions would be more regularly used. Of course, that is another of the problems cited with medical schemes arising from the CPA.

All in all, we may see some changes, but by and large these comments reflect a lack of appreciation for the actuarial realities of managing a health scheme with community rating.

Gaining new insight into insurer profitability through New Business Margin on Revenue

The Value of New Business written by an insurers is a good measure of the value created through sales activity over a certain period. It’s not the easiest number to interpret in terms of profitability though.

New Business Margin, which is the Value of New Business (VNB) as a percentage of the Present Value of New Business Premiums (PVNBP) is a common measure of profitability of that news business.

But it’s a flawed measure, especially when it comes to comparing product lines and insurers or even to understand the change in profitability from one period to the next. It uses and unequal yardstick to measure business.

New Business Margin on Revenue (NBMR) provides a significantly improved measure of profitability that can be used to compare margins across products, across insurers and across time. Further, it leads easily to a component analysis of the margin, adding additional insights to shareholders, brokers and regulators.

If you haven’t read my introductory post on New Business Margin on Revenue, it would be worthwhile doing so now – this post is going to illustrate the sort of results it provides in a practical, numerical example.

Example 1 considers how NBMR clarifies distortions from a change in mix of business.

Example 2 shows how more complex dynamics can be understood through a component analysis of NBMR. The spreadsheet showing the underlying calcs is attached at the end of this post. Continue reading →

New thoughts on renewal rates for Embedded Values

Embedded Values (EVs) are widely used to measure value for life insurers. In the context of long-term contracts such as individual life, it reflects the value embedded in prudent regulatory provisions (or “actuarial reserves”).

For short-term business (group risk, health insurance, health administration, general insurance etc.) it is something different since these lines don’t have long-term prudent provisions. In these cases it reflects the present value of future profits expected to be earned out of the existing business.

The inclusion of these short term types of business within EV is widespread. It seemingly increases consistency between different types of contracts since we are considering the long-term expected profitability in all cases. More on this apparent consistency in a moment.

What do we include in the EV and VIF?

EV is not a complete economic measure of the value of an insurer, since it ignores future profits arising from future new business. This is by design. An Appraisal Value incorporates the Value of Future New Business (VFNB) as well, although there is always subjectivity over how many years of future new business should be included. (More on this in a separate post.)

Existing Business vs Future Business

The idea of “existing business” and “future new business” is clear in the individual life context. It’s existing business if you have a contract, and future new business if not. Premium increases and slight benefit modifications can usually be accommodated within the existing contract and so should ideally be included in the Value of In Force (VIF) based on the expected probabilities of these changes.

In Bahrain for a few days

I’m in Bahrain for a few days kicking off an ERM implementation project. 35 degrees at 7am in Doha on the way there…

Bahrain has a population of around 1.2 million but has a well developed insurance sector. Economies of scale limit domestic growth and regional expansion faces tough competition and increased complexity. Will be interesting to see more.

A good explanation of the perceived problems of annuities

Posted on by

There is much to recommend in purchasing an annuity at retirement to manage the risks and uncertainty of longevity. It’s well known though that surprisingly few people who have the option to purchase an annuity do so.

Richard Thaler presents some of the common perception problems with annuities in this article in the NY Times. The basic message is still as it has been for decades. Individuals are reluctant to pay a large portion (often the majority) of their life savings to an insurer with the risk that they will die in a few years and “not have got their money back”. The peace of mind that should come to the policyholder turns into a matter of stress.

The bequeath motive is strong – and amplified by a lack of understanding of exactly how long we’re likely to live in retirement these days and how much money will be required. Those to whom many plan to bequeath may ultimately become the source of support when the income draw-down products are depleted with no longevity guarantee to boost the funds available.

It’s a good explanation although he doesn’t break much new ground. He also doesn’t talk about the concerns some potential policyholders have, in some countries at least, of whether the insurance company who sells the annuity will definitely be around over the next 40 years come what may.  This is more common in developing markets with weaker regulation (probably a good reason to have concerns) and less history of annuities (a cultural bias that will probably disappear over time).

Mr Thaler doesn’t propose any solutions for the insurers in boosting sales – a common “fix” is to combine a traditional pay-until-death annuity with a guaranteed minimum period or a death benefit (either for a limited term or at any point).  These adjustments reduce the “risk” of “making the wrong decision but purchasing an annuity but only living for a short period”.

There’s no free lunch.  In the same way that cash-back bonuses on short-term insurance products actually increase the average cost of insurance and reduce the risk-transfer from insured to insurer, these guarantee periods increase the cost of annuities.

New Business Margin on Revenue

A new measure of life insurance new business profitability is required.

What is New Business Margin?

Many life insurers currently calculate a measure of the profitability of new business sold over a period called “new business margin”. As defined by the CFO Forum’s MCEV Principles and confirmed in South Africa’s PGN107 covering embedded values, this is the Value of New Business (VNB) divided by the Present Value of New Business Premiums (PFNBP) calculated on a consistent basis.

This is a useful measure since it shows, on average, how much of each premium goes to shareholders as profit, after deducting operating costs, benefits paid to policyholders and a cost of the capital required to support the business.

It’s far more useful than a common previous metric of VNB / API where API is Annual Premium Income or APE Annual Premium Equivalent, since the numerator reflects a multi-year stream of profits and the denominator just a single year. It’s a more difficult number to interpret intuitively.

Of course, New Business Margin is also fatally flawed. Continue reading →

Fixed Interest is a viable asset class

Posted on by

I heard someone talking on Classic Business tonight. Pity I didn’t catch his name so I can avoid his advice in future.

He was saying that he doesn’t see the point in investing in debt instruments.  He explained that the return is low and the risk high since if the company gets into trouble, you’ll likely only get a few cents on the dollar back.

Well, he’s wrong.

Risk and asset-liability matching

Fixed Interest investments are often the only investment that makes sense when you need to match or hedge fixed liabilities.  Naively consdering expected return only and not asset-liability risks  gives naive results.

Credit risk premia more than compensate for default experience over time

It’s worth exploring risk a little further. The caller stated that if the company gets into trouble, it’s likely the bondholders will also be hurt, and will likely only get a few cents on the dollar. Well he’s wrong here too.

The historical default frequency for investment great bonds (BBB and above) has been hardly more than a few single digit percent.  The Loss Given Default (how much an investor will typically lose if the bond issuer does default) is anywhere from 35% to 80%, depending on the seniority of the instrument, which estimate you trust, how it is measured and when the estimate was made. It’s because there are so few investment grade defaults that the data is so sparse and the estimates so wide. However, it’s clear that the likely return won’t be “a few cents on the dollar”.

I’m going to hunt round for some references here so you’re not just trusting my word.

Illiquidity premia = higher returns for some

Given the illiquidity of many corporate bonds, the expected returns are even higher if you as an investors are not considered with easy liquidation of your investment. This is a “pure risk premium” that you will earn over time without expected loss.  You could purchase extremely high quality, well-collateralised debt and earn a good return above risk-free as long as you have the patience and resources to hold it for long periods or until maturity.
