bank's loan losses rise by 3.2% of assets to 4% next year. (We assume that other items on the income statement in Table 1-3 are unaffected.) The result will be a pre-tax net operating loss of 2.6% of assets (0.6 - 3.2 = -2.6). Assuming a tax rate of 30%, this would result in an after-tax loss of about 1.8% of assets. 税后1.8%是怎么算出来的？

第三种和第四种怎么结束债券了？

One measure of the performance of a bank is return on equity (ROE). Tables 1-2 and 1-3 show that the DLC's before-tax ROE is 0.6/5 or 12%. If this is considered unsatisfactory, one way DLC might consider improving its ROE is by buying back its shares and replacing them with deposits so that equity financing is lower and ROE is higher. For example, if it moved to the balance sheet 请问DLC 啥意思？

老师您好，为什么不是除以P的平方呢？

老师我可不可以这样理解，这题不用adjusted R^2 的原因：因为R^2是用来解释independent and dependent之间的关系的，因此，若想用adjusted R^2就必须说'keeping other independent variable unchanged'.
