Maintenance Margin

The money or securities an investor keeps in a margin account in order to be able to borrow from a brokerage for short sales or other purposes. The maintenance is kept as collateral until the brokerage calls the margin and the client pays back what is owed. FINRA requires that the maintenance kept must be at least 25% of the amount borrowed, while some brokerages require maintenances of up to 50%. See also: Restricted account.
