Cost and Expense Highlights
Operating costs and expenses were $29.5 million and $58.8 million for the three and the six months ended June 30, 2012, respectively, representing increases of $5.9 million and $13.4 million over the respective periods of 2011. These increases reflect incremental operating costs and expenses attributable to higher throughput levels and our recently acquired assets serving HFC’s El Dorado and Cheyenne refineries as well as year-over-year increases in depreciation expense, maintenance service and payroll costs and professional fees.
Interest expense was $11.3 million and $21.7 million for the three and the six months ended June 30, 2012, respectively, representing increases of $2.6 million and $4.5 million over the respective periods of 2011 due to higher year-over-year debt levels. Also, we recognized a loss of $0.4 million and $3.0 million for the three and six months ended June 30, 2012, respectively, on the early extinguishment of our $185 million 6.25% senior notes.
