cost of equity in the NPV base calculation. Question Five was generally well answered with most candidates being able to make a reasonable attempt at the NPV calculations and draw basic conclusions from the results. However‚ few were able either to calculate appropriate PIs based on rationed cash flows‚ or to “stand back” from the NPV and PI results and use these to help identify the best overall combination of projects. In the sections below that explain how the marking scheme was applied‚ where the

A 2.50 mole sample of NOCl was placed in a 1.50-L container at 400oC. When equilibrium has established‚ it was found that 28% NOCl has dissociated according to the reaction: 2NOCl(g) ⇄ 2NO(g) + Cl2(g) Calculate the equilibrium constant Kc (0.0356) 5.

Chapter 5 to calculate the yields of domestic bonds and Eurobonds. The main difference between the two is that domestic bonds pay interest semiannually‚ whereas Eurobonds pay annually. Due to this difference in the frequency of compounding‚ the student must be careful to compare the APYs of domestic and Eurobonds when trying to find the lower-cost alternative. Exhibit S-5-1 provides information concerning five Johnson & Johnson debt issues. Answers to Questions: 1. Calculate the APY for
