)计算债券成本=1500*10%*5*(1-33%)/4000*(1-1%)
=502.5/3960
=12.69%
2)计算优先股成本=股息年率/(1-融资费率)×100%
=12%/(1-2%)=12.24%
3)计算普通股成本=2000*12%/2000*(1-4%)+4%=16.5%
4)计算综合资本成本
筹资比例:债券4000/(4000+500+2000)=61.54%
优先股500/6500=7.69%
普通股2000/6500=30.77%
综合资本成本=12.69%*61.54%+12.24%*7.69%+16.5%*30.77%
=7.8%+0.94%+5.08%=14.54%
