Contract entitlements

What you are entitled to under each tier: allocation limits, contract classes, governance visibility, SLA, and the PRB minimum rule as a subscription control (minimum reserve you must maintain to stay entitled). How debits and accruals settle is covered under execution fees & settlement. Participation fees on each card are for tier comparison only; your active platform charges are summarized in the participation section above.
