Abstentions and limits

Abstention conditions

Known limitations

  • Preview capability: useful but incomplete eval or SME coverage; human review required.
  • Do not use for a full monthly cash forecast, hedge cash-settlement model, debt-service or fixed-charge test, legal covenant interpretation, borrowing-base determination, facility sizing, or a probability-of-default or probability-of-breach conclusion.
