Analyst also collected the cash flow information about PZ company in the following table:
The CFF includes cash paid for interest of 1260 and the CFO includes taxes of 1850 in 2018, please calculate the ratio of operating cash flow before interest and taxes to operating income for PZ for 2018 is closet to:
选项：
A.2.29
B.2.25
C.2.34
解释：
C is correct.
考点：operating cash flow before interest and taxes
解析：
Operating cash flow before interest and taxes=CFO+支付利息的现金+支付税的现金，这一题比较特殊，因为题目中说interest是属于financing activity的，不属于CFO，所以它没有在CFO中扣除。既然它没有在CFO中扣除，那也就不需要加回了.只需要加回tax即可，
Operating cash flow before interest and taxes=8850+1850=10700
将其除以EBTI得到：10700/4579=2.34
不是除以Operating Income吗？为什么除以EBIT?
