HollyFrontier Corporation owns and operates five complex refineries with an annual average crude oil capacity of approximately 443,000 barrels per day. Our refineries are complex refineries, which means that they can process heavier, less expensive types of crude oil and still produce a high percentage of gasoline, diesel fuel and other high value refined products. Each of our refineries has direct pipeline connections to major crude oil trading hubs within the United States, providing direct access to a wide variety of domestic and Canadian crudes, and also has access to regional, trucked crudes from local producers. Our subsidiaries manufacture and market lubricants and specialty products and commodity and modified asphalt products. We focus our marketing efforts throughout the mid-continent, southwestern and Rocky Mountain regions, which we believe are among the most attractive refined product markets in the United States.
