Fortunately, there is a simple formula that can help you understand the compensation a bank should receive for organizing and managing a transaction, often referred to as “success fees”. It's called the Lehman formula and is sometimes referred to as the Lehman scale. The commission given to a financial advisor (usually an investment bank) for successfully concluding a successful transaction is known as a success fee. It matches the interests of the client and the advisor, because the price is only paid if the client achieves his goal effectively.
