There has to be — just has to be — a lesson in this: Two weeks ago, 
business wires reported that former billionaire Sean Quinn had declared 
bankruptcy.
How someone who was worth $6-billion in 2008 could file for 
bankruptcy is somewhat mind-boggling. Sure, we have all heard of lotto 
winners or sports stars blowing through $5-million or $6-million on 
cars, houses and parties. But $6-billion? Come on.
Quinn, once Ireland’s richest man, was declared bankrupt after losing
 more than €1-billion ($1.3-billion) investing in Anglo Irish Bank Corp.
 The Irish Bank Resolution Corp. estimates Quinn owes the bank 
€2.9-billion. A court receiver is due to take over the Quinn’s family 
interest in Quinn Group, a business built on materials, insurance and 
real estate.
The bank’s heavy exposure to property lending, with most of its loan 
book being to builders and property developers, meant it was badly 
affected by the downturn in the Irish property market in 2008. In 
December 2008, the Irish government announced plans to inject 
€1.5-billion of capital for a 75% stake in the bank, effectively 
nationalizing it. The shares fell 99%.
Quinn had attempted to support the bank through special derivative 
contracts. As the collapse intensified, his losses multiplied. In the bankruptcy proceedings, it was alleged Quinn had sold assets worth $193-million to one of his cousins, for $1,000. 
Where do we even begin here, because there are so many lessons for investors from this sad tale?
First, as many, many people worldwide found out in 2008, real estate 
can actually decline in price. So many Baby Boom investors saw house 
prices go up in value for 40 years that everyone more or less forgot 
they could actually also decline in value. A lot. Hopefully, the 
2007-2008 real estate crash and anemic recovery is fresh enough in your 
mind that you won’t need a reminder of that anytime soon.
Second, debt can make you rich, if you borrow at the right 
time. There is nothing like paying 3% interest on an asset that has gone
 up 100%. Real estate moguls use debt like crack. But debt, like drugs, 
can also kill you. While Quinn seems to have had at least some personal 
restraint using debt, the bank he invested in did not. Having 5% equity 
(or less) and the balance in debt does not leave much room for error if 
asset prices move the wrong way. The slightest decline in value wipes 
out your entire equity. 
With the absolutely massive decline in real estate prices in Ireland 
during the crisis, Anglo Irish’s equity was more than wiped out, almost 
daily. That’s why it needed continual — and large — capital injections 
just to stay afloat before its eventual collapse.
Third, Quinn forgot one of the prime rules of true long-term 
investors — stay away from derivatives. Derivatives are a zero-sum game:
 Someone always loses. Sure, you can make lots of money, but someone on 
the other side loses the same amount.
Quinn dabbled in what’s known as “contracts for differences.” Don’t 
ask to me to explain what they are. Hopefully Quinn knew. Anyway, they 
did not work out, and as they declined in value, Quinn was on the hook 
for more and more money.
Finally, desperate investors do desperate things. The Quinn family 
says the allegations of asset transfers were “baseless and hardly 
deserving of comment.”
But there have been other allegations. Like a football team down 30 
points with two minutes left in the game, investors in trouble might try
 some crazy last-minute plays.
Make your life easier: Don’t get to Sean Quinn’s point. Stay away 
from leverage; stay away from derivatives; don’t go all-in on a sector; 
and stop throwing good money after bad investments.
