I've written before about life settlements. Generally, I'm a
fan of
allowing the business. More recently, I argued that people don't like unseemly parts of their investments when they draw too much attention. It's really a matter of
diversification.
This brings me to the latest controversy over the company
Life Partners Holdings Inc., a seller of fractional interest in life insurance policies. The company has just reduced their return expectations touted to customers, at least partially as a result of pressure from a
WSJ story. I know, this is a shocker: They could not deliver on their promised returns!! Oh, and they're being investigated by the SEC.
Here's the idea: Think of a life insurance policy as a
negative coupon bond with an
unknown maturity. Instead of receiving coupons, you pay coupons. Instead of getting back your principle at a known future date, you get it back at a random date. The longer the person lives, the lower your return, because you pay the coupon longer, and you get paid back your principle at a later date. Variable maturity combined with negative coupons makes these bonds
much riskier than typical bonds. (Of course the upside can be huge if the insured falls short of life expectancy.)
How risky are they? How many stories have you heard of people with months to live surviving years? My understanding is that there's excellent medical evidence that the grumpier the old man, the longer he lives.
The math isn't very difficult. If you expect someone to die in three years, and they live for four, intuitively you're at least 30% worse off, right? they lived 33% longer than expected, and you had to pay another year of premium. (At least there's upside: The insured may live less than three years.)
Many factors drive life expectancies, and they are just
expectancies: Half of all people will live longer than expected.
Moreover, those that are highly likely to live less than expected probably know this, and won't sell their policies.
Life actuaries will tell you your sample needs
thousands of observed deaths to draw credible conclusions. In other words, you need
massive diversification to reduce risk. Why is that?
In contrast, diversification in the stock market takes relatively few positions. Twenty or thirty stocks in various sectors get you most of the way there. A two or three thousand stock portfolio isn't going to deviate much from "the market" or our "expectations."
In it's history, LPHI has only sold 6,400 policies to 27,000 investors. It seems unlikely many of those 27,000 investors hold even 1000 different lives. They're undiversified and unrealistic about risk and return.
Frankly, it doesn't matter if the doctor in Reno, NV who performs all their medical evaluations is any good. He could be "perfect" at calculating
expectancies, and results may be lousy for undiversified investors. (However, giving him the benefit of the doubt is worse than giving credit rating agencies the benefit of the doubt when you buy mortgage backed securities!)
Think of it this way: Suppose the SEC were investigating an equity index mutual fund. Rather than holding all 500 S&P stocks like Vanguard, it held 10 or 15. Would you be surprised at the results when the fund underperformed the index? (But your friend would still brag at the party that his IRA beat yours!)
