问题 问答题

某公司2002年年初的股东权益总额为600万元(含优先股100万元,10万股),年资本保值增值率为160%(无客观因素影响所有者权益),2005年年初的负债总额400万元,股东权益是负债总额的3倍,年资本积累率50%,2005年年末的资产负债率40%,负债的年均利率为5%。2005年该公司的固定成本总额170万元,实现净利润308.2万元,所得税率33%。优先股股利为8.2万元,2005年末的股份总数为610万股,2005年的经营现金净流量为616.4万元,成本费用总额为500万元,2005年发放的普通股现金股利为150万元,2005年末的普通股市价为5元/股。

要求:

(1)计算2002年年末的股东权益总额;

(2)计算2005年年初的股东权益总额、年初的资产负债率;

(3)计算2005年年末的股东权益总额、负债总额、产权比率。

(4)计算2005年EBIT、总资产报酬率、净资产报酬率、已获利息倍数、3年资本平均增长率;

(5)计算2006年的DOL、DFL、DCL;

(6)计算2005年的成本费用利润率、盈余现金保障倍数、每股收益、每股股利、每股净资产;

(7)计算2005年末的市盈率。

答案

参考答案:

(1) 2002年年末的股东权益总额=600×160%=960(万元)

(2) 2005年年初的股东权益总额=400×3=1200(万元)

年初的资产负债率=400/(400+1200)×100%=25%

(3) 2005年年末的股东权益总额=1200+1200×50%=1800(万元)

负债总额=1800/(1-40%)×40%=1200(万元)

产权比率=1200/1800×100%=66.67%

(4) 2005年利息=5%×(400+1200)/2=40(万元)

EBIT=308.2/(1-33%)+40=500(万元)

总资产报酬率=500/[(1600+3000)/2]×100%=21.74%

净资产报酣率=308.2/[(1200+1800)/2]=20.55%

已获利息倍数=500/40=12.5

三年资本平均增长率=-1=23.31%

 (5) DOL=(500+170)/500=1.34

DFL=500/[500-40-8.2/(1-33%)]=1.12

DCL=1.34×1.12=1.50

(6) 成本费用利润率=利润总额/成本费用总额×100%

=[308.2/(1-33%)]/500×100%=92%

盈余现金保障倍数=经营现金净流量/净利润

=616.4/308.2=2

每股收益=(净利润-优先股股利)/(年末股份总数-年末优先股数)

=(308.2-8.2)/(610-10)=0.5(元/股)

每股股利=普通股现金股利总额/年末普通股总数

=150/(610-10)=0.25(元/股)

每股净资产=(年末股东权益-年末优先股权益)/年末普通股总数

=(1800-100)/(610-10)=2.83(元/股)

(7) 2005年末的市盈率=普通股每股市价/普通股每股收益=5/0.5=10

If phone calls and web pages can be beamed through the air to portable devices, then why not electrical power, too It is a question many consumers and device manufacturers have been asking themselves for some time. But to seasoned observers of the electronics industry, the promise of wireless recharging sounds depressingly familiar. In 2004 Splashpower, a British technology firm, was citing “very p” interest from consumer-electronics firms for its wireless charging pad. Based on the principle of electromagnetic induction (EMI) that Faraday had discovered in the 19th century, the company’s “Splashpad” contained a coil that generated a magnetic field when a current flowed through it. When a mobile device containing a corresponding coil was brought near the pad, the process was reversed as the magnetic field generated a current in the second coil, charging the device’ s battery without the use of wires. Unfortunately, although Faraday’s principles of electromagnetic induction have stood the test of time, Splashpower has not — it was declared bankrupt last year without having launched a single product.

Thanks to its simplicity .and measurability, electromagnetic induction is still the technology of choice among many of the remaining companies in the wireless-charging arena. But, as Splashpower found, turning the theory into profitable practice is not straightforward. But lately there have been some promising developments.

The first is the formation in December 2008 of the Wireless Power Consortium, a body dedicated to establishing a common standard for inductive wireless charging, and thus promoting its adoption. The new consortium’s members include big consumer-electronics firms, such as Philips and Sanyo, as well as Texas Instruments, a chipmaker.

Fierce competition between manufacturers of mobile devices is also accelerating the introduction of wireless charging. The star of this year’s Consumer Electronics Show held in Las Vegas was the Pre, a smart-phone from Palm. The Pre has an optional charging pad, called the Touchstone, which uses electromagnetic induction to charge the device wirelessly.

As wireless-charging equipment based on electromagnetic induction heads towards the market, a number of alternative technologies are also being developed. PowerBeam, a start-up based in Silicon Valley, uses lasers to beam power from one place to another.

It now seems to be a matter of when, rather than if, wireless charging enters the mainstream. And if those in the field do find themselves languishing in the disillusionment, they could take some encouragement from Faraday himself. He observed that “nothing is too wonderful to be true if it be consistent with the laws of nature.” Not even a wirelessly rechargeable iPhone.

What’s the final goal of the Wireless Power Consortium()

A.To turn the Faraday’s theory into profitable practice

B.To find ways for the consumer-electronics industry

C. To integrate consumer-electronics firms and chipmakers

D. To promote a common standard for inductive wireless charging
