Deferring to our Manufacturer (speculator), the manufacturer would be best served purchasing a put option so as to ensure the sums remitted at the point in time of delivery are sufficient so as to cover incurred costs while delivering a guaranteed return essential to long-term planning and secondary funding. At the point in time the contract matures, any additional return earned as a result of exercising the option becomes "gravy" because the cost associated with its acquisition would have been included in the original delivery contract with the buyer.
