This report is aimed at explaining and understanding the process of assets lifecycle costing and application of Terotechnology in evaluation of long-term investment in capital assets. Every business organisation invests major part of their capital in long-term capital assets, which helps in revenue generation for a longer period of time. Before making such an investment in the long-term capital assets, the costs and revenues associated with such investment must be analysed and evaluated to make a conscious investment decision. In this report a detail analysis has been done on the investment evaluation process with reference to the Terotechnology. Lastly the report concludes with some recommendation for improvement in the investment evaluation and appraisal process.
