# Bad debt socialization: how a lending loss reaches suppliers

Bad debt is borrowing that cannot be recovered from repayment or available collateral. Socialization allocates that shortfall across a defined set of participants. Morpho Vault V2 documents a share-price mechanism: when an adapter reports lower asset value and the vault recognizes it, the same shares can represent fewer assets.

## Key facts

- **Recognition:** A loss can exist before it is reflected in a particular accounting view. ([Handling Bad Debt: Morpho Vault V2](https://docs.morpho.org/curate/tutorials-v2/bad-debt/))
- **Share value:** Lower total assets can reduce assets redeemable per share. ([Handling Bad Debt: Morpho Vault V2](https://docs.morpho.org/curate/tutorials-v2/bad-debt/))
- **Version caveat:** The cited V2 guide identifies a V1.1 adapter loss-reporting limitation. ([Handling Bad Debt: Morpho Vault V2](https://docs.morpho.org/curate/tutorials-v2/bad-debt/))

## An unchanged share count can hold less value

Imagine a simplified vault with 1,000 assets and 1,000 shares. A recognized loss of 100, with no deposits, fees or other changes, leaves 900 assets. Ignoring virtual-share and rounding adjustments, 100 shares now correspond to 90 assets rather than 100.

No user share needs to be burned to make that loss real. The actual conversion follows the deployed contract’s arithmetic.

## Distinguish economic loss from its display

The V2 documentation uses adapters’ reported real asset values to update the vault. It also warns that a V1.1 vault allocation through the named legacy adapter may not pass its losses into the V2 share price. An apparently unchanged price can therefore require investigation of the underlying allocation.

## Identify who bears this loss

A market, vault and broader protocol are different boundaries. Determine which loans caused the loss and which holders share exposure through that market or vault. Management fees can continue during loss periods in the documented V2 design. A write-down is not a promise of later reimbursement.

## Questions

### If my receipt-token count stayed the same, did I avoid the loss?

Not necessarily. The amount of underlying assets represented by each receipt can fall.
