As New York state's largest nonprofit health plan, the company remains committed to three core principles:

We exist to assure, in the communities we serve, that as many people as possible have affordable, dignified access to needed, effective health care services, including long-term care.
We recognize the need, and our responsibility, to reach out to all segments of the communities we serve, particularly the poor and aged and others who are underserved, to enhance quality of life, including health status.
We are committed to being a nonprofit health insurer.
