Questions 17 to 20 are based on the following conversation between Dr. Smith and his student. You have 20 seconds to read Questions 17 to 20.W: Dr. Smith, there is now the question of being able to patent the new species of animals created by means of genetic engineering. What do you find so objectionable about thatM: The US patent office has recently decided that any animal on this planet can be patented! With the exception of man, that is. Well, what does this mean, exactly. It means that if you put a gene into an animal, you can claim that animal as your invention. Of course this is totally absurd. The patent office has, therefore, reduced the whole biological kingdom to the status of a commodity -a manufactured good, like an electric toaster or a car.In fact, they said living things are to be considered manufactured processes and compositions of matter.W: Well, I would agree with you that the idea is rather absurd. But, from a practical point of view.., surely you must agree that if millions of dollars have been spent developing a particular variety of rabbit by a company or university...well, surely they are entitled to protect their investment in a legal way.M: They are not entitled to take the common inheritance of this planet and turn it into private property. Horse, cows, sheep and goats.., even mice, have been here for millions of years. They are no one’s property. The idea of patenting them strains the bounds of rational thought.And this trend will have dramatic implications for farmers. If this patenting goes ahead, and spreads in Europe, it’ll mean that farmers will have to buy patented animals from chemical companies.., and pay royalties on their young.And every time farmers want to sell their animal, they will have to pay patent royalties. This is not only absurd, it’s thrilling.W: I think you’re right in this matter. Thanks. What has the US patent office recently said can be patented().

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
