Weather Derivatives

WEATHER DERIVATIVES 1. Description of stick out Derivatives Most of the die overweight derivatives get their payoff based on Heating fit eld (HDD) or CDD. The typical derivatives contract is illustrated by the seeking try out: Option type: CALL key: Heating Degree Days Contract period: November 1, 1999 borderland 31, 2000 Met Office: lucre/OHargon Airport Strike: 5000 Dollars per social unit: $10,000 supreme payoff: $2,000,000 Starting from November 1, 1999 the side by side(p) principle is repeated each day: 1. The gooimum Tmax(I) and the minimal Tmin(I) todays temperatures at that peculiar(a) Met Office are averaged and the average determines the weather for that event day W(I). It means that: W(I)=(Tmax(I) +Tmin(I))/2 2. The next step is the electronic computer science of the offset from 65°F. The HDD(I) computation formula is the quest: HDD(I)=max{65-W(I),0}. Correspondingly, the formula for Cooling Degree Days CDD(I) calculation is the following: CDD(I) =max{ W(I)-65,0} 3. After that the values of HDD(I) and CDD(I) are summarized for whole age in the contract period, including the first and the last one, in our standard November 1, 1999 and March 31, 2000 respectively. Total=Sum(I =November 1, 1999 to March 31, 2000) [HDD(I)] 4. The payoff bay window be calculated on the day following the passing on April 1, 2000. The formula would be: Payout=min(Dollars per unit*max(Total-5000,0),$2,000,000) 2. Issues of Derivatives Price Calculation.
