Zizig Company Limited (ZCL) is a listed company involved in agriculture. Its current land and processing plant are too small to meet the growing demand that it anticipates to have once it gets a permit for the construction of a new dam. It therefore seeks to expand its operations and is wary of a discount rate it can use as a hurdle rate in its decision making. To estimate this rate, they have been advised to consider estimating the weighted average cost of capital as a basis for identifying this hurdle rate. The following information is available. The current capital structure is shown below:

Debt, 9% coupon, K1,000 par K20,000,000

Preferred stock, 8% dividend,K50 K10,000,000

Common stock, K1 par K2,000,000

Retained earnings K68,000,000

TOTAL K100,000,000

New K1,000 par bonds can be sold at par with a 10% coupon. New K25 par Preferred stock may be sold at par with a k2.50 dividend per share. Dividends on the common stock have grown at a rate of 8% which is expected to continue. Next years dividend is expected to be K2.00 per share and the companys common stock whose beta coefficient is 1.5, currently sells over-the counter at K20.00 per share. The risk free rate is 6% and the return on the market portfolio is 15%. The company is in the 35% tax bracket.
