Company X currently has a capital structure that consists of 40% equity, 20% preferred equity, and 40% of debt. The risk-free rate is 3% and the market risk premium is 8%. The company's equity beta is 1.1. The dividend yield for the preferred equity is 6%. The corporate tax rate is 21%, and the cost of borrowing for company X is 5%. What is the WACC for company X

14.58%

Explanation:

WACC = weight of equity x cost of equity + weight of debt x cost of debt x (1 - tax rate) + weight of preferred equity x dividend yield

According to the capital asset price model: Expected rate of return = risk free + beta x (market rate of return - risk free rate of return)

r= 3% + 1.1 x 8 = 11.8

equity = 0.4 x 11.8% = 4.72

d = 0.4 x 5 x (1 -0.21) = 1.58

p = 0.2 x 6 =  1.2

11.8 + 1.58 + 1.2 =

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
