2. A) Describe what the realized compound yield (rcy) is, and B) Calculate it for each bond in the following cases: a) no change in reinvestment rates (rr), (reinvestment rate equal to the ytm); b) increase in the reinvestment rate, rr = 5%, and c) decrease in rr = 2%. (Hint: You may calculate the rcy in several ways, shown in the Excel le: teaching-120-xedincome-annotated-3.xlsx For example, given that the maturities are the same as the one in the Excel le, one way is to use the table starting in \"bond terms, Realized compound yields, G26\". Another, more straightforward way is the one shown in \"bond terms, U49\
