Volume Growth - We believe waste volumes are driven by population growth, household formation and new business formation. Volume growth through increases in our customer base and service offerings is the most capital efficient method to grow our business. We seek to obtain long-term contracts for collecting solid waste under residential collection contracts with municipalities, exclusive franchise agreements, and small-container commercial and large-container industrial contracts. By obtaining such long-term agreements, we can grow our contracted revenue base at the same rate as the underlying economic growth in these markets. In addition, by securing a base of long-term recurring revenue, we are better able to protect our market position from competition. We work to increase volumes while ensuring that prices charged for services provide an appropriate return on our capital investment.
