Unformatted text preview: must be equal to the value
of Firm L. In summary, firm value is independent of the debt policy.
Consider an alternative investment strategy where we consider investing only in 1 percent of L’s equity.
Alternatively, we could have borrowed 1% of firm L's debt, DL, in the bank and purchased 1 percent of
The investment in 1% of Firm L's equity yields 1% of the profits after interest payment in return.
Similarly, borrowing 1% of L's debt requires payment of 1% of the interest, whereas investing in 1% of U
yields 1% of the profits.
Investment Return 1% of Firm L's equity 1% · EL = 1% · (VL - DL) 1% · (Profits - Interest) Borrow 1% of Firm L's debt and
purchase 1% of Firm U
- Borrow 1% of L's debt
- 1% of U's equity -1% · DL
1% · EU = 1% · VU -1% · Interest
1% · Profits = 1% (VU - DL) = 1% · (Profits - Interest) It follows from the comparison that both investments return 1% of the profits after interest payment.
Again, as the profits are assumed to be identical, the value of the two investments must be equal. Setting
the value of investing 1% in Firm L's equity equal to the value of borrowing 1% of L's debt and investing
in 1% of U's equity, yields that the value of Firm U and L must be equal
- 1% · (VL - DL) = 1% · (VU - DL) VL = VU The insight from the two examples above can be summarized by MM's proposition I:
Miller and Modigliani's Proposition I...
