Last week, a story by Steven Mufson and Juliet Eilperin declared that Koch Industries was “the biggest lease owner in Canada’s oil sands.” This claim was made in the headline and opening paragraph. After receiving some push-back, the pair wrote a follow-up claiming that Koch is only “one of the region’s largest,” citing figures showing that other companies had larger confirmed holdings and unnamed industry sources who believe Koch’s holdings are greater than the 1.1 million acres reported. In other words, the reporters no longer stood by the claim made in the headline and lead. Moreover, when Phil Kerpen checked the official records, he found that a Canadian company’s holdings exceed all estimates of Koch holdings and may be more than double those owned by Koch. If the numbers Kerpen compiled are correct, Koch is not the largest lease owner, even if it owns more than the 1.1 million acres confirmed in story.
