We entered the natural gas marketing business in an effort to maximize the utilization of our portfolio of natural gas pipeline and storage assets. Our natural gas marketing activities generate revenues from the sale and delivery of natural gas obtained from (i) third party well-head purchases, (ii) regional natural gas processing plants and (iii) the open market. In general, our natural gas sales contracts utilize market-based pricing and can incorporated differentials for factors such as delivery location. We expect our natural gas marketing business to continue to expand in the future.
