请问altman，zscore要背过吗

老师好，能不能再讲一下反向签约和提前结算这一块，我没太听懂

A、B都属于non-operating G/L里的unusual or infrequent items吗？

求助下为啥我在计算年金题目的时候，即使使用了2nd-CLR TVM进行数据清除，并且正负号还有为0的选项都输入了，但是计算结果还是错的。我只能选择2nd-Reset 才能完全恢复。请问这种情况只能用Reset功能吗？考试时候还可以怎么快速清除之前的数据？

视频1小时34分钟的这道题能否再讲下，谢谢。

15 An independent audit report is most likely to provide:A absolute assurance about the accuracy of the financial statements.B reasonable assurance that the financial statements are fairly presented.C a qualified opinion with respect to the transparency of the financial statements.C选项错误的原因是什么？是因为qualified opinion不是指财报的透明度要求对吧？

brokerage fee是什么呢，如何产生的

23 Which statement is most accurate? A common size income statement:A restates each line item of the income statement as a percentage of net income. B allows an analyst to conduct cross-sectional analysis by removing the effectof company size.C standardizes each line item of the income statement but fails to help an analyst identify differences in companies’ strategies老师能解释一下C选项为什么同比利润表可以识别公司的不同战略吗？

麻烦老师能给再详细讲讲这句话的含义吗？
