DD plc is a vegetarian food manufacturing company, operating in the UK and some parts of the Europe. Currently, some of their productions such as smoothies and non-diary milk have been outsourced due to lack of available resources. However, strategic managers of DD plc are looking to invest in a project producing smoothies or non-diary milk. They have called new business proposals and have finally, chosen two projects using managers' discretion to make final decision. Initial investment required for project A (smoothies) is 158,000 and for project B (non-diary milk) is 155,000. The discount rate required is at 15%. The net cash flows for two projects can be summarized as below:
