Exactly one year ago, you bought a certain item on a forward basis with delivery $3$ years later. When the contract was concluded, the product was priced according to the futures at SEK $428\mathrm{.}32$ at the end of the term. The price was then calculated on the basis of an annual interest rate of $5\mathrm{.}50\%$ plus a cost of storage. The storage cost is expressed as a percentage of the spot price for the day the item is stocked and applies for the entire time period with a fee of $9\mathrm{.}30\%$ for $3$ years, $6\mathrm{.}20\%$ for $2$ years and $3\mathrm{.}10\%$ for $1$ year. Suppose the spot price for the commodity is $$375\mathrm{.}00$ today and the storage cost is calculated in the same way as a year ago, but the annual interest rate is now $6\mathrm{.}00\%.$ How much risk$-$free profit can you secure at the end of the term?
