As a not-for-profit service provider, we exist solely for the benefit of our customers: our member companies, the persons entitled to benefits, and policyholders. We strive at all times to act as a sympathetic, helpful partner, offer a competent, practical service and thus create tangible added value. That is what we are here for.
