In this paper, we extend the "static model" in Milevsky and Salisbury (2006) by considering a more realistic situation that VA could lapse during the guaranteed period if the annuitant dies earlier. And if this happens, remaining annuity payments discontinue, whereas a death benefit will be offered to maintain the minimum withdrawal guarantee.

本文的研究基础建立在Milevsky and Salisbury (2006)的静态模型上，并且加以考虑变额年金被保险人在保证期间内死亡的情况；若变额年金被保险人於保证期间内死亡，其死亡给付必须能够维持原GMWB承诺之权益。

Therefore, in this article,we first discussed the compound negative binomial, it able to simultaneously fitthe claim size and the claim number. At the same time, we studied the sum of themutually independent compound negative binomial and the sum of the mutuallyindependent compound negative binomial with discount factor and the sum of themaximal compound negative binomial; Next, for the claim data to be better fitted, this article has establishedthe superposition distributed model about the weighted average of the discreterandom and has discussed the estimation method of the parameters of thesuperposition distribution; Once more, we in detail elaborated the NCD which based on the claim numberand the NCD which based on the claim size and the claim number. Besides, weestablished an applied NCD model which also based on the claim size and the claimnumber; At last, we introduced the rewards and punishment coefficient of automobiletravel region into the applied NCD model, availably consummated the present NCD.

因此，本文首先讨论了能拟合索赔额大小和索赔次数的复合负二项分布，并对相互独立的复合负二项分布的和、带有折现因子的相互独立的复合负二项分布的和以及最大复合负二项分布进行了研究；其次，为了更好地拟合索赔数据，本文建立了离散随机变量加权平均的叠加分布模型，并讨论了其中的权数的估计方法；再次，本文详细阐述了基于索赔次数的无赔款优待系统、考虑索赔次数和索赔额大小的无赔款优待系统以及应用型的同时考虑索赔次数和索赔大小的无赔款优待系统；最后，本文在无赔款优待系统中引入了汽车行驶区域奖惩系数，对现行的无赔款优待系统进行了完善。

Derivatives also create a daisy-chain risk that is akin to the risk run by insurers or reinsurers that lay off much of their business with others. In both cases, huge receivables from many counterparties tend to build up over time.(At Gen Re Securities, we still have $6.5 billion of receivables, though we've been in a liquidation mode for nearly a year.) A participant may see himself as prudent, believing his large credit exposures to be diversified and therefore not dangerous. Under certain circumstances, though, an exogenous event that causes the receivable from Company A to go bad will also affect those from Companies B through Z. History teaches us that a crisis often causes problems to correlate in a manner undreamed of in more tranquil times.

衍生性金融商品交易也有可能造成骨牌效应的风险，这是因为许多保险业及再保业者习惯将风险分散给其它保险公司，在这类的情况下，钜额的应收款项将随着交易对象的日趋复杂而持续累积，(以通用再保证券来说，虽然已经经过将近一年的清算期，目前仍有高达65亿美元的应收款项流通在外)，交易的一方或许对于自己相当有信心，认为其钜额的信用风险已经经过适度的分散，因此不会发生任何危险，只有等到某种特殊状况下，一个外部事件导致 A 公司的应收帐款发生问题，从而影响 B 公司，乃至于一路到 Z 公司，历史教训告诉我们危机的发生往往是我们在太平盛世时所梦想不到一连串问题串连所导致的。

The need to meet this demand can then throw the company into a liquidity crisis that may, in some cases, trigger still more downgrades. It all becomes a spiral that can lead to a corporate meltdown.
