Growth capital expenditures include costs related to the following: 1) acquisition capital expenditures that are necessary to transition and upgrade acquired assets to Company operating standards and to achieve strategic synergies associated with integrating newly acquired operations, which can be considered, together with acquisition purchase price, as part of the initial overall investment in an acquired business; 2) McKean Landfill rail capital expenditures, which is unique and different from landfill construction investments in the normal course of operations because the Company is investing in long-term infrastructure; and 3) development of landfill permit expansions, investment in infrastructure to increase throughput at transfer stations and recycling and other processing facilities, capital expenditures for new equipment, such as trucks, containers or compactors, to support new contracts or other organic business growth, and other development projects in support of our growth strategies. Replacement capital expenditures are defined as landfill cell construction costs not related to expansion airspace, costs for normal permit renewals, replacement costs for equipment and other capital expenditures due to age or obsolescence, and capital items not otherwise defined as growth capital expenditures.
