Modigliani and Miller's (M&M's )Propositions states that
capital structure i.e the level of equity and debt in the company
doesn't affect the total value of the company .Whether the company
is leveraged or un- leveraged the value of the company doesn't get
affected .
Some assumptions of this theory are
So M&M'S
I Proposition was that capital structure doesn't affect the value of the company . The priority is same for both equity and debt holders.The reasoning behind this is value of the firm is dependent on the present value of future cash flows of the firm so capital structure couldn't affect it .
VL = Vu
Where ,
VL = Value of leveraged firm (debt + Equity )
VU = Value of unleveraged firm (only equity )
II Proposition was that the leverage was directly proportional to cost of equity , and with rise in leverage the default probability will also rise and equityholders should be compensated with higher cost of equity as they assume more risk .
rE= rA + D/E ( rA- rD )
where rE = Cost of levered equity
rA = Cost of unlevered equity
rD = Cost of debt
D/E = Debt-to-equity ratio
Now using first proposition we can say that Value of unleveraged firm is equal value of leveraged firm
So if Unlevered Firm was equal $100 Million
The New Leveraged Firm will also Equal $100 Million
Now Using Second Proposition we can find the increased required return for the leveraged equity
rE= rA + D/E ( rA- rD )
So here
D/E =1:1
ra =10%
rd = 6%
Now Using this is equation we get
rE = 10 + 1(10-6)
rE = 14%
So after using leverage the cost of equity has risen from 10% to 14%
