⁽¹⁾  Represents transfers, valued on a market price basis, from the refinery to the airline segment for use in airline operations. We determine market price by reference to the market index for the primary delivery location, which is New York Harbor, for jet fuel from the refinery.

⁽²⁾  Represents value of products delivered under our exchange agreements, as discussed above, determined on a market price basis.

⁽³⁾  Represents sales of refined products to third parties. These sales were at or near cost; accordingly, the margin on these sales is de minimis.

⁽⁴⁾  Includes the impact of pricing arrangements between the airline and refinery segments with respect to the refinery's inventory price risk.
