The more firms get from obligation as opposed to issuing stocks, the more it can diminish the aggregate cost of capital in light of the fact that the enthusiasm from obligation is duty deductible which will help reduce the aggregate cost of capital. In any case, no firm can get from obligation everlastingly in light of the fact that, at one point in time, extra obligation financing will make the aggregate cost of capital increment rather than decline. So firms will get in view of their own enhanced capital structure to limit the aggregate cost of capital however much as could reasonably be expected. Also, in light of this upgraded capital structure, there is a point of confinement to how much a firm can keep getting from obligation.
