问题 单项选择题

Selected information from Caledonia, Inc.’s financial activities in the year 2006 was as follows: Net Income was $ 460000. 2300000 shares of common stock were outstanding on January 1. The average market price per share was $ 2 and the year-end stock price was $1.50. 1000 shares of 8 percent, $1000 par value preferred shares were outstanding on January 1. Dividends were paid in 2006. 10000 warrants, each of which allows the holder to purchase 100 shares of common stock at an exercise price of $1.50 per common share, were outstanding the entire year. Caledonia’s Diluted earnings per share (Diluted EPS) for 2006 was closest to:

A.

A. $0.165.

B.

B. $0.180.

C.

C. $0.149.

答案

参考答案:C

解析:Caledonia’s basic earnings per share (EPS) ((net income-preferred stock dividends)/weighted average common shares outstanding) was ((($ 460000-($ 1000×1000×0.08))/2300000=) $0.165. Using the treasury stock method, if the warrants were exercised, cash inflow would be (10000×100×$1.50=) $1500000. The number of Caledonia shares that could be purchased with the inflow, using the average share price, was ($1500000/$ 2=) 750000. The net increase in common shares outstanding would have been (1000000-750000=)250000. Diluted EPS was ($380000/(2300000+250000=) $0.149.

单项选择题 A3/A4型题
填空题

(12分)镍电池广泛应用于混合动力汽车系统,电极材料由Ni(OH)2、碳粉、氧化铁等涂覆在铝箔上制成。由于电池使用后电极材料对环境有危害。某兴趣小组对该电池电极材料进行资源回收研究,设计实验流程如下:

已知:①NiCl2易溶于水,Fe3不能氧化Ni2

②已知实验温度时的溶解度:NiC2O4>NiC2O4·H2O>NiC2O4·2H2O

③某温度下一些金属氢氧化物的Ksp及沉淀析出的理论pH如下表所示:

M(OH)nKsp开始沉淀pH沉淀完全pH
Al(OH)31.9×10-233.44.2
Fe(OH)33.8×10-382.52.9
Ni(OH)21.6×10-147.69.8
