A fraudulent investment scheme. Investors are promised very high returns by the promoter. The original investors often realize these high returns because their payouts are funded by cash from new investors. New investors' cash is used to pay out the original investors. The investors' funds are usually not applied to the stated purpose. However, the reported high returns attract additional inflows of capital used to pay out subsequent investors. The scheme fails when the payouts to existing investors and/or redemption requests exceed new investor inflows.
