The same page in Stella's book Pretax Income=(EBIT - INT):

DFL = EBIT / Pretax Income

and

DFL = %delta in Pretax Income / %delta inEBIT

how can they be the the same by inversing the Numerator and denomerator from two equation, just w/o a %delta?
 
I'm pretty sure DFL = % change in EPS/ % Change in Ebit. Regardless, it measures how much EPS grows with a change in EBIT, based upon the assumption of more debt. More profit flows through to the shareholders.

I.e. Consider a company with an EBIT of $100, last year, that is tax exempt with 10 shares outstanding. If EBIT increases to $200 under a no debt situation EPS increases
by $10 or 100%. I.e.
EPS = 100/10 = 10
EPS' = 200/20 = 20

Now consider a Debt situation. If the company issues bonds and has to pay $50 in the form of interest each, they may have issued half as many shares or have only 5 outsatnding. If in this case EBIT increases from 100 to 200 dollars
EPS = 100-50/5 = 10
EPS' = 200-50/5 = 30

This indicates that the company is more levered and more profit flows through to shareholders.

my concern is why they are equivalent, by reverse the num and denom, people can check Stella's study guide 11-94, or Stella's Lecture Note 11-48
 
It's mathematically correct, and I don't have the time nor the patience to rehash the appendix. Also, there is no reversal of the denominator, it's a percentage change, which is not equatible to EBIT/EBIT-I (which is EBIT/Pre Tax Income) = (%-Change EPS/%-change EBIT) and if you can't get that I would go over that chapter with a fine toothed comb.
 
Hi,

It goes this way.............

Assume Pretax Incomes Old & New to be Po & P1 respectively.
Similarly EBIT Old & New to be Eo & E1.

DFL = %Change in Pre-Tax Income / %Change in EBIT
= [(P1 - Po)/Po] / [(E1 - Eo)/Eo]
= Eo/Po [Since (P1 - Po) = (E1 - Eo)]

See the following example for clarifications.

Capital structure: Equity = 50,000 & Debt = 50,000 @ 10%


ITEM , Year 1 & Year 2

EBIT , 100,000 & 150,000

Interest Expense , (5,000) & (5,000)

Profit before Tax , 85,000 & 135,000

Tax @ 40 % , 34,000 & 54,000

Net Profit after tax , 51,000 & 81,000


Notice that since absolute change in Profit before Tax & EBIt is the same here (because Debt Capital is not changed, thus no change in Interest expense) the DFL formula can further be converted to EBIT/Profit before Tax.

DFL = % cahnge in Pretax income / % change in EBIT
= 58.824 / 50.00
= 1.1765

Again, DLF = EBIT / Pretax income
= 100,000 / 85,000
= 1.1765


Hope this helps.
