Leveraged Buyouts

Here is a short Tutorial about leveraged buyouts (LBO)

An LBO firm (such as Carlyle, the Apollo Group) is acting along the following line:
1. Identify a firm that is inefficiently managed (call it target)
2. Obtain a bridge loan from a bank (say $10 billion)
3. Use the loan to purchase the stock of the target in addition to $0.200 billion of its own equity
4. Once the LBO firm owns 100% of the target's equity, it makes it borrow A LOT (say $9.8 billion)
5. The LBO firm makes target pay it a dividend of $10 billion
6. The LBO firm repays the bank
Final result:
The LBO firm invested $200 million in a highly leveraged target.
If target does well, the LBO firm is bound to double or triple its money. This is usually carried out by selling the levered company to a third party or by selling it in a public stock issuance. If the opposite is true, the target will go bankrupt and the LBO is not likely to recoup its $200 million investment.

Where else can the process fail?
By the time the takeover deal is finalized, the bank may withdraw the bridge loan leaving the LBO firm in hot waters.
