Contractual Settlement and Income The Custodian may, as a matter of bookkeeping convenience, credit the Account with the proceeds from the sale, redemption or other disposition of Securities or interest, dividends or other distributions payable on Securities prior to its actual receipt of final payment therefor. All such credits shall be conditional until the Custodian’s actual receipt of final payment and may be reversed by the Custodian to the extent that final payment is not received. Payment with respect to a transaction will not be “final” until the Custodian shall have received immediately available funds that under applicable local law, rule or practice are irreversible and not subject to any security interest, levy or other encumbrance, and that are specifically applicable to such transaction.
