Whether the potential acquisition is a natural gas plant, pipeline, terminal, refinery, or other hydrocarbon facility – the approach is similar. It is necessary to: 1) scrutinize the asset’s historical financial and operating performance; 2) examine the existing supply and off-take contracts in place; 3) evaluate the asset’s present physical condition; 4) review the asset’s performance relative to the competitors; 5) analyze both positive and negative acquisition consequences; 6) understand and model the market; 7) develop a financial performance model; and 8) conclude a range of values for the asset.
