We are an integrated global provider of specialty catalysts, materials and chemicals, and services that enable environmental improvements, enhance consumer products, and improve personal safety. Our value-added products seek to address global demand trends that are often either the subject of significant environmental and safety regulations or are driven by consumer preferences for environmentally friendlier alternative products, which we believe positions us to grow sales in excess of gross domestic product growth rates and provides us with high-margin growth opportunities. Specifically, our products and solutions help companies produce vehicles with improved fuel efficiency and cleaner emissions. Our materials are critical ingredients in consumer products that make teeth brighter and skin softer. We produce highly engineered materials that make highways and airports safer for drivers and pilots. Because our products are predominantly inorganic and carbon-free, we believe we contribute to improving the sustainability of our planet.
