The group's principal activity is to develop and manufacture generic and brand pharmaceutical products. The group operates through two segments: generic segment and brand segment. The generic segment manufactures generic pharmaceutical products that are therapeutically equivalent to a brand name product. These products are marketed to pharmaceutical wholesalers and distributors, drug store chains, group purchasing organizations, institutions and governmental agencies. The brand segment manufactures branded pharmaceutical products that are generally patent protected products marketed directly to health care professionals by a single provider.
