Marketing, Clients and Competition Our industrial services are marketed principally by personnel based at our service locations. We believe that these service locations are situated to facilitate timely responses to client needs with on-call expertise, which is an important feature of selling and providing our services. The capacity and capability scope of our discrete and integrated services also allows us to benefit from the procurement trends of many of our clients who are seeking to reduce the number of contractors and vendors in their facilities, as well as to outsource more of such services.
