Reading 27 官方教材 Q10：关于EGREPS的取值，讲义中注释为 "expected real growth in GDP"。 对应题目中我根据这段话：“...Stock returns over 2004 to 2006 reflect the setbacks but economists predict the country will be on a path of a 4 precent real GDP growth by 2009." ——故而用4%作为EGREPS的取值。 但是答案中用的是5%。我猜是取值于"earnings in the public company sector are expected to grow at a 5% Per year real growth rate."。我知道 expected growth in real earning per share 可以视同 real GDP growth，但为什么前面提到的经济学家预测的真实GDP增长率不能用在Ibbotson-Chen公式里？

Reading 27 官方教材 Q9：烦请解释答案中最后两句话 （1）the short term interest rate, however, overstates the long term expected inflation：首先题干中的前提"current interest rate environment"对应case情景描述的哪个部分？其次，利率怎么影响通货膨胀的？ (2）Using the short-term interest rate, estimates of the long term required return on equity will be biased upwards：若根据题干，RoE 是（短期国债，历史ERP）的函数，ROE的估值为什么会受到利率的影响？

The author of a new textbook received a $100,000 advance from the publisher this year. $40,000 of income taxes were paid on the advance when received.

C $100,000. 查看解析 上一题 下一题 正确答案A 您的答案A本题平均正确率：46% DTA & DTL难度：一般 推荐：      答案解析 For revenue received in advance, the tax base is equal to the carrying value minus any amounts that will not be taxed in the future. Since the advance has already been taxed, $100,000 will not be taxed in the future. Thus, the textbook advance liability has a tax base of $0 ($100,000 carrying value - $100,000 revenue not taxed in the future). 请问：这里涉及到tax base的公式吗？洪老师视频里没有讲到有关税基的计算，可否公式化说明
