Hi, I need to calculate the Weighted Average Cost of Capital for Apple's Inc.. Please if you can help as soon as possible I would greatly appreciate it.

a.Calculate the WACC

i.Determine the market capitalization of the firms common equity and preferred equity, if any.

ii.Determine the firms capital structure based on the market value of the firms equity and debt. The market value of the firms debt can be obtained from the Morningstar website, listed in the Cost of Debt section above.

iii.Calculate the WACC. As you recall, the formula for WACC is r_WACC = E (E + D) r_E + D (E + D) r_D (1 - T_C).
