Modigliani-Miller Propositions 2
WACC is unaffected by capital structure
Modigliani-Miller with taxes
Debt financing creates a tax shield that increases company value
Cost of capital minimized and value of the firm is maximized at 100% debt
Cost of financial distress (MM)
1) Legal and administrative fees from bankruptcy
2) Loss of trust, foregone investment opportunities
3) Agency costs of debt: managers represent equity owners
Static trade-off theory
A firm’s optimal capital structure is the proportion of debt at which the value of the tax shield from additional borrowing just offsets the increase in costs of financial distress.
Agency cost
1) Monitoring cost
2) Bonding cost
3) Residual losses
Pecking Order Theory
Managers want to send the least amount of negative signal. And prefer the following sources of capital in order:
1) Retained earnings
2) Debt
3) New equity
Observed capital structure is the result of the manager’s choices over time.
