FIN343 Bank estimates that building a new branch office in the newly developed New Heaven township will yield an annual expected return of 10percent with an estimated standard deviation of 6percent. The bank's marketing department estimates that cash flows from the proposed New Heaven branch will be strongly positively correlated (with a correlation coefficient of + 0.70) with the bank's other sources of cash flow. The expected annual return from the bank's existing facilities and other assets is 8percent with a standard deviation of 5 percent. The branch will represent just 15percent of Lifetime's total assets. Will the proposed branch increase FIN343's overall rate of return? Its overall risk?
