问题如下：
A company has 1 million shares outstanding and earnings are £2 million. The company decides to use £10 million in idle cash to repurchase shares in the open market. The company’s shares are trading at £50 per share. If the company uses the entire £10 million of idle cash to repurchase shares at the market price, the company’s earnings per share will be closest to:
选项：
A.£2.00.
B.£2.30.
C.£2.50.
解释：
C is correct.
At the current market price, the company can repurchase 200,000 shares (£10 million/£50 = 200,000 shares). The company would have 800,000 shares outstanding after the repurchase (1 million shares − 200,000 shares = 800,000 shares).
EPS before the buyback is £2.00 (£2 million/1 million shares = £2.00). Total earnings after the buyback are the same because the company uses idle (nonearning) cash to purchase the shares, but the number of shares outstanding is reduced to 800,000. EPS increases to £2.50 (£2 million/ 800,000 shares = £2.50).
老师好， 如果这题用EPS repurchase 后= (NI收购前- repurchase price )/ (shares before repo - shares repurchased) 该怎么做？ NI收购前 是否为$million ? 谢谢。
