## Default

Default occurs when a borrower fails to meet the obligations of a loan agreement. In a margin account, this happens if the investor cannot meet a margin call or if the account equity becomes negative.

When a default occurs, the broker will typically liquidate all positions and take control of the remaining assets to recover the loss.
