Average natural gas and oil revenues per unit of production for ERC's production associated with NYMEX contracts will reflect the impact of basis differentials. Average NGL revenue per unit of production will be net of transportation and fractionation fees. For production associated with basin-specific contracts, ERC will receive the contracted hedge price and typically hedges basis differentials where applicable. The basin-specific contract prices have been converted for comparability purposes to a NYMEX-equivalent price by adding to them ERC's assumed basis differentials.
