We are one of the leading cement producers in the Philippines, based on installed annual capacity as of December 31, 2015, according to the Cement Manufacturers Association of the Philippines. We produce and market cement and cement products, such as ready-mix concrete and clinker, in the Philippines through direct sales using our extensive marine and land distribution network. Our cement manufacturing subsidiaries have been operating in the Philippines for over 17 years, and have well established brands, such as APO, Island and Rizal, each of which has a multi-decade history in the Philippines. Our brand recognition and customer-centric direct sales approach have helped us develop a long-term customer base.
We offer a broad product mix and work closely with other CEMEX companies to develop and introduce innovative products to the Philippine market. We offer bag cement and bulk cement, with bag cement accounting for over 80% of our cement sales in the year ended December 31, 2015, but with demand for bulk cement increasing as the number of infrastructure projects in the Philippines grows. In 2013, we began producing and selling ready-mix concrete, which allows us to provide customers with a variety of specially designed concrete mixes to meet the challenges of modern construction. Sales of cement and cement products accounted for 99.4% of our combined net sales before eliminations resulting from combinations for fiscal 2015.
