Summit Global Management employs a value investment approach that seeks to achieve consistent long-term returns while minimizing risk. The firm specializes in investments in global hydrocommerce and other industries that are directly impacted by water. Summit builds portfolios one company at a time and invests in undervalued securities that are identified through the analysis of fundamental, company-specific information. The firm looks for companies in which the market price of their securities is appreciably less than the intrinsic value of the operation as a whole. Summit determines the company's intrinsic value through proprietary research, advanced analytical tools, direct management communication and an extensive network of contacts.


A Cabrini education starts with this premise: students have the potential to do something extraordinary with their lives, and Cabrini surrounds them with opportunities to tap their potential to the fullest. Cabrini is a coeducational Catholic college near Philadelphia where students from a variety of backgrounds come together in a close-knit learning community offering challenging academics and a foundation in values. In both the residential undergraduate program and in graduate studies programs, Cabrini provides an education of the heart, asking students to explore moral and ethical questions, while preparing them for rewarding careers and lives of responsible citizenship. In all programs, classes are small, faculty are accessible, and learning connects classroom theory to real-world practice through internships, fieldwork, independent research projects, programs abroad, and other experiences. And all programs reflect a mission that flows from Cabrini’s Catholic heritage: to provide an education that prepares students not just for career success, but for lives of dignity and purpose as well.
