NATURAL GAS LIQUIDS
Natural gas liquid prices reflect closing prices at Mont Belvieu, Texas. For propane, this location reflects storage in the Louis Dreyfus system. For ethane, butane, isobutane and natural gasoline, this location reflects storage in the Enterprise system.

Ethane: 95% minimum purity, 0.3546 desnity
Propane: 0.5077 density
Butane: 0.5844 density
Isobutane: 0.5631 density
Natural gasoline: 0.664 density, 0.1% maximum sulfur content, 81 degrees API gravity, 12-14 RVP

OLEFINS
Ethylene prices reflect closing prices in three defined storage and transmission systems : Equistar at Mont Belvieu, Williams at Mont Belvieu, and Petrologistics at Choctaw (Louisiana).

Ethylene: 99% minimum purity
Refinery grade propylene: 65% minimum purity (contained in propane stream)
Polymer grade propylene: 99.5% minimum purity
Chemical grade propylene: 94% minimum purity

RESINS
Resin prices reflect closing prices on a railcar basis in the Houston area. Resins are generic prime, which is the same quality as branded prime but without supplier branding. +/- reasonable and producers accepted variance to maintain their prime certification.
