Within this time horizon, all of the surplus and premiums less claims collected are reinvested in either zero coupon bonds or the stock market; which believed to follow similar movement to the share prices of AMP Limited (AMP). However at any time when the funds go insolvent, then all future cash flows are cancelled. This report aims to provide the essential information regarding this innovative flood insurance policy, which include: * The premium charged for the flood insurance product every year. * The amount of the capital needed to be contributed by the shareholders in the beginning of this policy. * Make selection for the most favourable investment policy between stocks or zero coupon bonds, with the surplus of premiums over claims. Furthermore, this report will also present the integral information on the * Profit and Loss Distribution of this policy at the end of the third year * Expected Value and Variance of the Profit or Loss * Probability of Loss * Expected Value of Loss, if a loss occurs ("Excepted Shortfall") DETERMINATION OF PREMIUM AND CAPITAL In order to calculate the level of premium and capital, it is essential to firstly, consider the amount of expected amount of aggregate claim. I. Estimation of claim Since this insurance policy provides cover for flood risks, the aggregate claim amount is assumed to follow a "compound Poisson" model. The total amount of aggregate claim in year t can be expressed as: Where N(t) ...read more.

Reasoning for expected aggregate claim Denote the number of claims by N(t) and the loss distribution for the ith claim by X(i,t) for i = 1,2,3,...,N(t). The number of claims that occurs takes the values N(t) = n(t). Moreover the total claim payments (aggregate loss) is denoted by S. The aggregate loss is the sum of all claim amounts that occur during the policy year. Accordingly S = X(1,t) + X(2,t) + X(3,t) + ... + X(N(t)) = The expected claims cost will be the expected value of the aggregate claims such that E[S] = To evaluate this probability, conditional probability is utilised. This means the different number of possible claims that will occur and the probability that these numbers of claims occur, so the expected aggregate loss is E[S] = With the losses being independent of the number of claims and each loss X(i,t) has the same probability density �x (x) then = E[X| N(t) = n(t)] = [xi] �x (x) dx = E[Xi] = n E[X] Therefore E[S] = n E[X] Pr[N(t) = n(t)] = E[n(t)] E[X] Since the average number of claims are 4.5, thus E[n(t)] = 4.5 and E[X] = 20000 ?E[S] = Expected aggregate claim = 4.5 ? 20000 = $90 0008 ?

However, positive assets are rounded off to the nearest 10,000s for the purpose of the evaluation of profit or loss distribution. Excel function for column A(3): if(stock(3)+ZCB(3)-AC>=0, stock(3)+ZCB(3)-AC,0) These groups are tabulated and tallied before the distribution graph is plotted, Refer to graph 2. The variant of the profit or loss distribution can be calculated using the variant formula. Var[X] = E[(X - E[X])2] To do this by excel, one extra column is created for the calculation of (X - E[X])2(1/7000) where 1/7000 is the probability for each value of x. In this case x is the value of profits and E[X] is the average of the profits. The sum of this column will give the variance of the profits, which equals to 6,319,587,035.

    Prisons simply do not eliminate crime and criminal behavior.

Prisons do very little to improve offenders unlawful habits. When they are released, a good percentage of them commit another offence, are re-arrested and convicted.
