Overcollateralization
Definition
Overcollateralization is the amount by which pledged collateral exceeds the outstanding debt it supports. In private credit and asset-backed structures, it is usually expressed as a percentage cushion above investor principal.
Why it matters
Overcollateralization is one of the first-loss cushions protecting lenders from collateral deterioration. A deal with 27.5% overcollateralization can absorb more losses than a similarly priced deal with no collateral cushion, all else equal. The quality, liquidity, and verification of the collateral still matter.
Common misconceptions
- •Overcollateralization is not the same as guaranteed recovery.
- •The percentage is only as good as collateral valuation and verification.
- •A high cushion can disappear quickly if collateral is concentrated or marks are stale.
Technical details
Simple calculation
Overcollateralization = (collateral value - note principal) / note principal.
Example: $1.275M collateral supports $1.0M notes. OC = 27.5%.
Minimum OC thresholds can restrict reinvestment or trigger protective actions when breached.
