Final answer:
John makes a profit of $5000 and Kate incurs a loss of $5000 when comparing the spot price of silver at the delivery date with the forward price agreed upon in the contract.
Step-by-step explanation:
Profit or loss for both John and Kate can be calculated by comparing the spot price of silver at the delivery date with the forward price agreed upon in the contract.
For John, who is the counterparty to the transaction, the profit or loss can be calculated using the formula: Profit/Loss = (Spot Price - Forward Price) * Quantity.
For Kate, who goes long to buy silver, the profit or loss can be calculated using the formula: Profit/Loss = (Forward Price - Spot Price) * Quantity.
In this case, the spot price of silver on the delivery date is $1100, and the forward price agreed upon in the contract is $1000 per ounce. The quantity traded is 50 ounces.
For John: Profit/Loss = ($1100 - $1000) * 50 = $5000 profit.
For Kate: Profit/Loss = ($1000 - $1100) * 50 = $5000 loss.
