(Q1) -15 points total Sennheiser is considering a project that will cost $100 million and will generate expected free cash flows of $40 million per year for three years. The interest rate is 12 percent. After discussions with the marketing department, you learn that there is a 20 percent chance of high demand, with future free cash flows of $60 million per year. There is a 50 percent chance of average demand, with free cash flows of $50 million per year. If demand is low due to new Covid variants (a 30 percent chance), free cash flows will be only $10 million per year. Suppose this project has an investment timing option, and it can be delayed for a year. After one year you will know whether or not the demand will be low due to new Covid variants. The cost will still be $100 million at the end of the year, and the cash flows for the scenarios will still last three years. However, you will know the level of demand, and will implement the project only if it adds value to the company. What is the expected NPV of this project with the investment timing option? What is the incremental value of the investment timing option? (To receive full credit, show the calculations below) High 20,60= Average 50,50= Low 30,10= Expected NPV with investment delay = Incremental value of investment timing option: Should you: (a) implement project now; (b) wait 1 year; or (c) forego project altogether (choose one)?

Homework (Ch 15) Which of the following statements correctly describe discouraged workers? (If none of the choices apply, leave all of the checkboxes blank.) Check all that apply. They are dissatisfied with their current jobs and are considering quitting. They are full-time workers who would like to work only part-time. They have not looked for a job in 4 weeks (or longer), but they would like a job and are available for work. They are counted as part of the labor force by the Bureau of Labor Statistics.

15. A electric utility wants to build a new coal fired power plant in an urban setting. The regulatory agency has determined that in order for the plant to be permitted it must limit its emissions to prevent the ground level SO$_2$ concentration from exceeding 0.015 g/m$^3$ at the site fence line 0.5 km directly downwind (y = 0) from the stack. What is the maximum SO$_2$ discharge rate (g/s) the plant can emit? Use the following: Effective stack height = 50 m Wind speed = 1 m/s Stability Class C, using Martin's equation: $s_y = 104.0X^{0.894}$ and $s_z = 61.0X^{0.911}$ where the dispersion coefficient is in meters and the X distance is in km $x = \left(\frac{Q}{\pi s_y s_z u}\right) \exp\left(-\frac{1}{2}\left(\frac{y}{s_y}\right)^2\right) \exp\left(-\frac{1}{2}\left(\frac{H}{s_z}\right)^2\right)$
