Modigliani- Miller (M-M) proposition 1: The worth of the steady is identical despite of if it investments itself with liability or equity. The weighted mean cost of capital: ra is constant. But, when D/E ratio is advised too tall, both equity-holders and debt-holders shall activate requiring higher comes back so that cost of capital of steady shall rise. Hence, There lives the optimal, pricing minimizing worth of D/E ratio. The market worth of the steady is granted by: Equity + Debt = E + D = V. The target of executives is maximization of firm's worth i.e. of its share cost (no bureau problems). Debt investment is lower than equity investment (rd < re), because equity is many dodgy than debt. According to traditional theory whether the steady alternates accountability for equity, it shall decrease its pricing of capital so expanding firm's value. Assumptions of M-M includes flawless and frictionless markets, none transaction charges, no default risk, none taxation, both companies and investors can scrounge at identical rd concern rate.

Example
Consider two firms: one has none liability while else is leveraged (i.e. has debts). They are equal in every else respect. In specific they possess identical mark of functioning profits: X. Let A possess thousand portions dealt at 1 euro and B possess handed out 500 (1 euro) portions and 500 euro of debt. (Myers 187-221)

If not, arbitrageurs shall possess money-making systems at their disposal. (Baker 1-32)

Firm B is overvalued with esteem to A. An driver owning 1% of B can: sell his portions of B for the market worth of 400; borrow 300 (i.e. 1% of liability of B) at rd = 12% buy 1% of A for the worth of 667. (Myers 187-221)
He otherwise owns 1% of unleveraged steady but has the liability identical to 1% of that of B. His risk is unchanged. Before he had the anticipated arrive back of 64 (=0.16*400). Now he still possess the come back of 64 (he anticipates to obtain 100 = 0.15*667 but he has towards yield 36 as interests). But: before he had bought into 400 of his cash, now alone 367=667-300
Hence it is money-making to deal B ( overvalued shares) and purchase A ( undervalued ones). The cost of A increases and that of B falls. The list displays the likely site of equilibrium: ra is same as it should be since, via hypothesis, A and B possess identical level ...
