In early 2013, Yahoo reports that AT&T has a market beta of:	0.66
and that its closing stock price at the end of 2012 was:	$33.71
AT&T's statutory tax rate is:	37%

1.Assume the market premium equals: 5.0%and that the risk-free rate equals: 2.5%.Estimate AT&T's cost of equity capital using the CAPM model. (Round to one decimal place.)

2.Footnote 9 of AT&T's 10-K reports that the market value of its debt approximately $81.31 billion. Calculate the company's intrinsic value of debt and equity.

intrinsic value of debt = ?

intrinsic value of equity = ?

3.Assume that AT&T's after tax cost of debt is 3.25%. Using this information and your rounded answers from above and from part (b), estimate AT&T's weighted average cost of capital. (Do not round until your final answer. Round to one decimal place.)

WACC = ?
