A researcher has determined that a two-factor model is appropriate to determine the return on a share. The factors are the percentage change in GNP and an interest rate. GNP market return is expected to be 12.9 percent and interest market return is expected to be 8.1 percent. The share has a beta of 1.2 on the GNP and 0.8 on the interest rate. If the risk-free rate is 11 percent, calculate the required rate of return on the share.
