幺点

We want to emphasize three points:(1) While we expect our super-cat business to produce satisfactory results over, say, a decade, we're sure it will produce absolutely terrible results in at least an occasional year;(2) Our expectations can be based on little more than subjective judgments - for this kind of insurance, historical loss data are of very limited value to us as we decide what rates to charge today; and (3) Though we expect to write significant quantities of super-cat business, we will do so only at prices we believe to be commensurate with risk.

我们有三点必须要强调(1)我们预期霹雳猫的业务长期来讲，假设以 10 年为期，应该可以获得令人满意的结果，当然我们也知道在这其中的某些年度成绩可能会很惨(2)我们这样的预期并非是基于客观的判断，对于这样的保险业务，历史的资料对于我们在做订价决策时并没有太大的参考价值(3)虽然我们准备签下大量的霹雳猫保单，但有一个很重要的前提那就是价格必须要能够与所承担的风险相当，所以若我们的竞争对手变得乐观积极，那幺我们的量就会马上减少，事实上过去几年市场价格有点低的离谱，这使得大部分的参与者都被用担架抬离场。

The zero-coupon or PIK bond possesses one additional attraction for the promoter and investment banker, which is that the time elapsing between folly and failure can be stretched out. This is no small benefit. If the period before all costs must be faced is long, promoters can create a string of foolish deals - and take in lots of fees - before any chickens come home to roost from their earlier ventures.

此外零息与 PIK 债券还有一项特点使得支持者与银行家更愿意推行，就是东窗事发的时间可以再延长，这点可是相当的重要，如果交易所衍生的后果要很长一段时间才会浮现，那幺支持者就可以在这段期间做更多的交易，从中赚取更多的手续费，直到事件东窗事发之前。
