YTM = 15.5%Before-tcost of = 15.5%Market value of equity = 1 million shares outstanng + 1 million newly issueshares= 2 million shares $8 = $16 millionTotmarket capitalization = $2.156 million + $16 million = $18.156 millionLeverebeta = 2.27 {1 + [(1 − 0.23)(2.156/16)]} = 2.27 (1.1038) = 2.5055Cost of equity = 0.0525 + 2.5055 (0.07) = 0.2279 or 22.79%weight = $2.156/$18.156 = 0.1187Equity weight = $16/$18.156 = 0.8813TagOn’s M= [(0.1187)(0.155)(1 − 0.23)] + [(0.8813)(0.2279)]= 0.01417 + 0.20083= 0.2150 or 21.50% 我的步骤都是对的 但是发现计算器按出来结果错了 导致后面的结果错了 主要是关于百分号的地方在计算Re的时候，应该是5.25%+βe*7% βe=2.5056我是这么按的 2.5056-- x -- 7 -- % -- + -- 5.25 -- % -- = 最后结果是0.1846 我发现主要问题出在算加法这部分 2.5056*7%这里都是正确的，算出来时0.1754 但是如果我直接用0.1754+5.25然后再按%，最后结果就不对了，就算我加上括号0.1754 -- + -- ( -- 5.25 -- % -- ) 这样算下来还是0.1846 我应该怎么按才对呢？
