1 Pursuant to Instruction 4 to Item 2.01 of Form SD, because the U.S. federal government has levied a payment obligation at the entity level rather than on a particular project, Occidental Petroleum Corporation has disclosed the entity-level payment and has not excluded amounts attributable to particular business segments or projects (each as defined in Form SD) unrelated to the commercial development of oil, natural gas or minerals.
