ABC公司正在考虑改变它的资本结构，有关资料如下：
(1)公司目前债务的账面价值1 000万元，利息率为5%，债务的市场价值与账面价值相同；普通股4 000万股，每股价格1元，所有者权益账面金额4 000万元(与市价相同)；每年的息税前利润为500万元。该公司的所得税率为15%。
(2)公司将保持现有的资产规模和资产息税前利润率，每年将全部税后净利分派给股东，因此预计未来增长率为零。
(3)为了提高企业价值，该公司拟改变资本结构，举借新的债务，替换旧的债务并回购部分普通股。可供选择的资本结构调整方案有两个：①举借新债务的总额为2000万元，预计利息率为6%；②举借新债务的总额为3 000万元，预计利息率7%。
(4)假设当前资本市场上无风险利率为4%，市场风险溢价为5%。
要求：
(1)计算该公司目前的权益成本和贝他系数(计算结果均保留小数点后4位)。
(2)计算该公司无负债的贝他系数和无负债的权益成本(提示：根据账面价值的权重调整贝他系数，下同)。
(3)计算两种资本结构调整方案的权益贝他系数、权益成本和实体价值(实体价值计算结果保留整数，以万元为单位)。
(4)判断企业应否调整资本结构并说明依据，如果需要调整应选择哪一个方案

阅读下面短文,按要求完成短文后的题目。

     Maybe Snoopy is the coolest dog in the world; maybe Snoopy is one of the greatest kids on two

legs. He is a happy-go-luck(逍遥自在的)dog everyone loves.

     Snoopy is the pet of Charlie Brown, whose name Snoopy could never remember. For Snoopy, his

master is just "that round-headed kid" who brings him his meals.

     Snoopy never speaks, but he can make himself understood by using facial expressions(面部表情)

and thought balloons(思想泡泡).

    ①In Snoopy's little head, he is everything but a dog. Since 1960s, Snoopy has been standing on two

legs instead of four and doing independent thinking. Here are two perfect examples to prove this point.

    Charlie once told Snoopy, "Look, Snoopy, that boy throws a branch, then his dog will run to pick it

and bring the branch back." Hearing this, Snoopy picked up a branch and threw it.

    At another time, Charlie read his newspaper to Snoopy, "It says that there will be a dog-show. Will

you think about it?" Snoopy thought, "How can I? I don't even have a dog!"

1、What does Snoopy think of his master?
