Our vision is to be the most innovative, respected and responsible leader in our markets - delivering performance that makes a difference. Our "advancing the core" corporate strategy is to extend our leadership in performance materials by investing for growth in our core businesses, driving application innovation with our customers, and generating strong cash flows through efficiency and optimization. Our products are generally based on technical expertise and innovation in one or more of our four core competencies: making and handling very fine particles; modifying the surfaces of very fine particles to alter their functionality; designing particles to impart specific properties to a formulation; and combining particles with other ingredients to deliver a formulated performance intermediate or composite. We focus on creating particles, and formulations of those particles, with the composition, morphology, and surface functionalities to deliver the requisite performance to support our customers' existing and emerging applications.
Through June 28, 2019, our business was organized into four reportable segments: Reinforcement Materials; Performance Chemicals; Purification Solutions; and Specialty Fluids. We divested our Specialty Fluids business as of June 28, 2019 and since that time have been organized into the three remaining segments. We routinely evaluate our portfolio in light of our growth strategy and will continue to evaluate strategic options for our Purification Solutions segment. Our business segments are discussed in more detail later in this section.
