第6题

在分析期初,Bird公司总资产为20亿美元,其中10亿美元为经营性资产,余下10亿美元为现金。公司无负债,有1000万股发行在外的股份。公司的经营方针是:始终保持无负债,并且每年年初将其净利润的2/3(=0.666)作为净投资(资本投资+营运资本的净增加-折旧)。分析师预测,公司每年经营资产回报率(净利润/年初经营性资产)为9%。

a)使用分析师的预测,今年Bird公司“股权自由现金流”是多少?假设公司所持有的现金不产生利息。(四舍五入至百万美元,并以百万美元为单位)

b)Bird公司的当前股票价格是150美元。假设公司股票的要求回报率为10%,计算Bird公司股票的理论价格。公司的股票定价是溢价还是折价?

c)Bird公司的管理人员考虑在今年用10亿美元现金开展一项新业务。如果新业务的年度经营资产回报率(净利润/年初经营性资产)为12%,且新业务每年所产生的净利润的一半作为对新业务的净投资。假设新业务风险与现有业务的风险相同,公司股票的理论价格是多少?

d)Animal公司在检查了Bird公司的现金之后,对Bird公司股票的估价为每股250美元,并计划用25亿美元现金收购Bird公司。Bird公司也因此暂停了新业务,并接受收购计划。结果Animal公司的股票价格从提出收购计划之前的500美元涨至800美元。两家公司在收购之前的情况如表1所示。Animal公司的股东从收购中获得的总利润将是多少?(四舍五入至百万美元,并以百万美元为单位)

e)现在假设Animal公司通过股权置换方式对Bird公司进行收购,Animal公司1股换Bird公司2股,置换后Animal公司的股价升至800美元。Animal公司股东获得的总利润是多少?(四舍五入至百万美元,并以百万美元为单位)

f)通过获取股份来收购一家公司时,即便收购价格相同,是采用现金购买还是用换股的方式来完成收购,收购方和被收购方的股东获得的利润都可能会产生变化。请说明在哪些情形下采用换股的方式能让收购方公司的股东获得更大的利润。

第7题

In Ethiopia there are nine national parks,two of which include the mountain groups of the Simien and
the Bale,while the others lie in the Rift Valley towards Kenya.The unforeseeable wild landscapes are surely the main attraction of these parks,where many of the animal species are protected,and some of them are endemic to the area.The proximity of Ethiopia to the Equator and the variety of its habitats make it one of the richest countries in Africa in wild bird life.

Passage Two

Questions 26 to 30 are based on the following passage.

Scientists have established that influenza viruses taken from man can cause the disease in animals. In addition,man can catch the disease from animals. In fact,a great number of wild birds seem to carry the virus without showing any evidence of illness. Some scientists conclude that a large family of influenza viruses may have evolved in the bird kingdom,a group that has been on the earth 100 million years and is able to carry the virus without contracting the disease. These are even convincing evidence to show that virus strains are transmitted from place to place and from continent to continent by migrating birds.

It is known that two influenza viruses can recombine when both are present in an animal at the same time. The result of such recombinations is a great variety of strains constraining different H and N spikes. This raises the possibility that a human influenza virus can recombine with an influenza virus form. a lower animal to produce an entirely new spike.

Research is underway to determine if that is the way that major new strains come into being. Another possibility is that two animal influenza strains may recombine in a pig,for example,to produce a new strain which is transmitted to man.

According to the passage,scientists have discovered that influenza viruses______.

A. cause ill health in wild birds

B. do not always cause symptoms in birds

C. are rarely present in wild birds

D. change when transferred from animals to man
