# Considerations for Creating Activity-Based Currencies with Mixed-Expiration Subcurrencies

Here are some considerations for currencies that use the Activity With Mixed Subcurrencies expiration model.

- The currencies don't support negative balances. This restriction exists because negative balances are evaluated at the parent currency level, whereas this model relies only on subtypes for point transactions.
- The currencies use aggregate ledgers for tracing. See [Track Redemptions and Associated Accruals with Traceability](https://help.salesforce.com/s/articleView?id=xcloud.loyalty_activity_mixed_expiration_track_redemptions_traceability.htm&release=264.0.0&type=5 "Trace consumed points to their originating source by using traceability loyalty ledger records. Traceability records map target debit ledgers to source Loyalty Aggregated Point Expiration Ledger records. If a single debit ledger consumes points from multiple aggregate ledgers, Loyalty Management creates a dedicated traceability record for each aggregate ledger from which points are consumed.").

Note The currencies don't support ledger tracing.

- You can't reinstate points for subcurrencies that use the fixed-duration expiration model.
