Your company must ensure the safety of its work force. Two plans are being considered for the next 10 years: 1. Install a high electrified fence around the property at a cost of $100, 00. Maintenance and electricity would then cost $5,000 per year over the 10 year life of the fence. 2. Hire security guards at a cost of $25,000 paid ate the end of each year. Because the company plans to build new headquarters with a “state of the art” security system in 10 years, the plan will be in effect only until that time. Your company’s cost of capital is 15% for average risk projects. Plan 1 is considered to be of low risk because its costs can be predicted quite accurately. Plan 2, on the other hand is a high-risk project because of the difficulty of predicting wage rates. What is the proper PV costs for the better project?
