A leveraged buyout (LBO) is a financial transaction in which a company is purchased with a combination of equity and debt, such that the company's cash flow is the collateral used to secure and repay the borrowed money. The use of debt, which has a lower cost of capital than equity, serves to reduce the overall cost of financing the acquisition. The cost of debt is lower because interest payments reduce corporate income tax liability, whereas dividend payments do not. This reduced cost of financing allows greater gains to accrue to the equity, and, as a result, the debt serves as a lever to increase the returns to the equity.
The term LBO is usually employed when a financial sponsor acquires a company. However, many corporate transactions are partially funded by bank debt, thus effectively also representing an LBO. LBOs can have many different forms such as management buyout (MBO), management buy-in (MBI), secondary buyout and tertiary buyout, among others, and can occur in growth situations, restructuring situations, and insolvencies. LBOs mostly occur in private companies, but can also be employed with public companies (in a so-called PtP transaction – Public to Private).
As financial sponsors increase their returns by employing a very high leverage (i.e., a high ratio of debt to equity), they have an incentive to employ as much debt as possible to finance an acquisition. This has, in many cases, led to situations in which companies were "over-leveraged", meaning that they did not generate sufficient cash flows to service their debt, which in turn led to insolvency or to debt-to-equity swaps in which the equity owners lose control over the business to the lenders.
LBOs have become attractive as they usually represent a win-win situation for the financial sponsor and the banks: the financial sponsor can increase the rate of returns on his equity by employing the leverage; banks can make substantially higher margins when supporting the financing of LBOs as compared to usual corporate lending, because the interest chargeable is that much higher. Banks can increase their likelihood of being repaid by obtaining collateral or security.
The amount of debt that banks are willing to provide to support an LBO varies greatly and depends, among other things, on:
