PART THREE Valuation of Securities Several factors influence a bond's risk premium. The financial condition of the borrower as measured by some of the ratios we studied in Chapter 3 ( e.gr, profitability ratios, debt ratios, interest coverage ratios) is related to the likelihood that a corporation will fail to make payments on its bonds, called default risk or credit risk. As the chapter opener explained, Aston Martin paid a much higher risk premium on its bonds than did Apple because Aston Martin's finan. cial condition was tenuous, whereas Apple's finances were rock solid. Different bonds issued by the same company may have different risk premiums as well. In its 2019 bond sale, Apple issued several different bonds that varied in terms of maturity and other features, and based on those characteristics the risk premiums on the bonds ranged from

to

above the Treasury rate at the time, Finally, when interest rates in the economy change, bond prices move in the op. posite direction, a phenomenon called interest rate risk. Some bonds are more sensitive to interest rate risk and therefore pay higher risk premiums to compen. sate investors for that risk.

Two mutually exclusive projects offer the following cash flows at years 0, and 1: Project 0 1 X–240 580 Y–10,060 11,010 Calculate an incremental IRR (crossover) of doing project Y and, on that basis, decide which project is preferable if the appropriate hurdle rate for each project is 8%. Group of answer choices incremental IRR = 6.21% so that project X should be done incremental IRR = 6.21% so that project Y should be done incremental IRR = 5.03% so that project X should be done incremental IRR = 6.52% so that project Y should be done incremental IRR = 6.52% so that project X should be done

If the following argument is an instance of one of the "famous" argument forms (either a famous deductively valid form or a famous invalid form), name the form and indicate whether the form is deductively valid or invalid; if the argument is not an instance of one of the "famous" forms, simply write "unnamed form." If the argument is invalid, provide a good counterexample to prove that it is invalid. Canada does not directly control the governments of countries other than itself. But Canada directly controls the governments of countries other than itself if Canada is a neo-colonial power. Hence, Canada is not a neo-colonial power.
