Answer:
c. convert the dollars to rupees in the spot market today and convert rupees to dollars in one year at today's forward rate.
Step-by-step explanation:
In the given case, Thornton requires to buy foreign currency i.e Nepalese rupees. So today, it needs to sell it's own currency i.e USD at current spot rate and purchase 5 million Nepalese rupees in return.
Now, since it will be in receipt of Nepalese rupees after one year and since US Dollar being a stronger currency, it is exposed to risk in case of US Dollar further strengthens over the period, the proceeds upon conversion would be lesser, resulting into a loss.
To hedge it's position against such a risk of currency fluctuation, Thornton would enter into a one year forward contract wherein it'll sell Nepalese rupees received after one year at a predetermined forward rate today and thereby limit it's loss.
