An expression reputed to have been coined by investor Warren Buffett,referring to a situation in which high-ranking insiders use their own money to buy stock in the company they are running.Most often,it refers to a lender aversion to 100 percent financing,even if the property is worth well more than the loan,because the lender wants the owner or developer to “have some skin in the game”and some equity to lose if the deal goes bad.
