The subsidiaries of Duke Energy that conducted this business were contributed to us in March 2000 immediately prior to the combination of these subsidiaries with the North American midstream natural gas business of Phillips Petroleum Company. For periods prior to the March 31, 2000 combination, Duke Energy Field Services, LLC and these former subsidiaries of Duke Energy collectively are referred to as the "Predecessor Company." (2) Interest expense on a historical basis was primarily from intercompany debt. In addition, the historical advance accounts from the parent companies were non-interest bearing. As a result the historical capital structure is not indicative of the current capital structure. For purposes of calculating the ratios of earnings to fixed charges: (1) "earnings" means income before extraordinary changes plus income taxes and fixed charges, and (2) "fixed charges" include interest on indebtedness, amortization of deferred financing costs, and that portion of lease expense that is deemed to be representative of an interest factor. The ratio includes amounts from our company, all of our majority-owned subsidiaries and our proportionate share of distributed amounts from 50% owned investments accounted for using the equity method.
