Even if the price of oil or natural gas declines, the business of KMP is not directly affected because it is paid to transport the commodity (energy transfer volume). Furthermore, it has a lot of throughput contracts with its clients. This means that KMP and its clients have contracts that established a minimum amount of the commodity that KMP ought to deliver. Whether or not the clients actually take delivery, they still have to pay KMP the agreed upon price for the delivery. This essentially puts a floor on their revenues.
