Suppose Royalty Pharma's portfolio consists of equally-weighted royalty interests in 40 approved and marketed biopharmaceutical products. Assume each royalty stream has an annualized expected return of 6.5%, and return standard deviation of 20%.

a) If the correlation amongst projects is 10%, then what is the annualized expected return of the portfolio. (Note: Your answers should be numbers in percentage form. Do not enter '%'.)

b) Still assuming that the correlation amongst projects is 10%, what is the return standard deviation of the portfolio. (Note: Your answers should be numbers in percentage form. Do not enter '%'.) THE ANSWER FOR THIS ONE IS 7%

c) If the distribution of portfolio returns is given by a normal distribution, then what is the probability that Royalty Pharma's equity holders suffer a loss greater than 10%? Assume an approximately even mixture of debt and equity: $4.2 billion and $4.0 billion, respectively. In addition, for simplicity, assume the yield on Royalty Pharma's debt is 0%. (Note: Your answer should be a number in percentage form. Do not enter '%'.)

d) What is the probability that Royalty Pharma's equity holders suffer a loss greater than 10% if the correlation amongst projects turns out to be 40%, instead of 10%?

Can you please indicate the answers to the correlating letter?
