Definition of 'Kicker'
1. A right, exercisable warrant, or other feature that is added to a debt instrument to make it more desirable to potential investors by giving the debt holder the potential option to purchase shares in the issuer. The kicker may or may not actually be usable; often a certain breakpoint must be reached (such as a stock price above a certain level) before the kicker has any real value.
2. In real estate, an added expense that must be paid on a mortgage in order to get a loan approved. An example would be an equity stake in receipts of a retail or rental property.
Investopedia explains 'Kicker'
1. Kickers are essentially features that are added to "get the deal done", as they are exclusively for the benefit of lenders and used to add to their expected return on investment (ROI). A company that adds a kicker (for example, a rights offering) to a bond issue is only doing so because it will help get the entire issue into the hands of investors.
2. Real estate kickers can be shady practices, even illegal in some jurisdictions.
