Exhibit 1

foreign Interest rate (annualized) 2%
time to maturity in days 92

The assumption for the calculation of hedging updates and forward contract valuations are given in the table above. Moreover, the formula for put delta is given below
E-qt*(N (d1)-1)
(Jorian, 2009)
The d1 in the above formula will be calculated in the diagram below

The put option’s delta calculations are available in the excel file, where we can see that all the values of beta are negative, which indicates that these are put option’s delta. Using these values’ further calculations are made for forward contract in order to calculate appropriate hedging procedure.

On the other hand, we can see that there is a portion, which is still uncovered. Whenever we update the time to maturity and spot prices, the delta is recalculated and this is how the portfolio is aligned. The result of the change held in delta and the portion which is uncovered in the overall process is given below:


Net proceeds from forwards 1,960,673
Proceeds from uncovered' 7,243,181
