However, historical operational practices and accidents have created significant environmental liabilities in the industrial sector, and now require significant investments for appropriate management and resolution. A strategic approach is imperative to assure that company’s financial resources are effectively allocated, and shareholders’ interests are protected. In addition, these liabilities must be appropriately and continuously reported, which require the use of robust forecasting techniques such as Monte Carlo Simulation. The present study results demonstrate that under an optimized strategic approach, liability management costs may be reduced in approximately 50%. In addition, the financial forecast under the selected approach may support appropriate reporting of company’s liabilities.展开更多
