An Authorized Participant who places a purchase order is responsible for crediting its Authorized Participant Unallocated Account with the required Bullion deposit amount by the second business day in London or Zurich, as applicable, following the purchase order date. Upon receipt of the Bullion deposit amount, the Custodian, after receiving appropriate instructions from the Authorized Participant and the Trustee, will transfer on the second business day following the purchase order date the Bullion deposit amount from the Authorized Participant Unallocated Account to the Trust Unallocated Account and the Trustee will direct DTC to credit the number of Baskets ordered to the Authorized Participant’s DTC account. The expense and risk of delivery, ownership and safekeeping of Bullion until such Bullion has been received by the Trust shall be borne solely by the Authorized Participant. If Bullion is to be delivered other than as described above, the Sponsor is authorized to establish such procedures and to appoint such custodians and establish such custody accounts in addition to those described in this prospectus, as the Sponsor determines to be desirable.

The first paragraph under the subheading “— Redemption Procedures – Delivery of redemption distribution” on page 57 is amended and restated in its entirety to read as follows:

The redemption distribution due from the Trust will be delivered to the Authorized Participant on the second business day following the redemption order date if, by 10:00 AM New York time on such second business day, the Trustee’s DTC account has been credited with the Baskets to be redeemed. If a loco swap or physical transfer is necessary to effect a loco London or loco Zurich redemption, the redemption distribution due from the Trust will be delivered to the Authorized Participant on or before the fifth business day following such a loco London or loco Zurich redemption order date if, by 10:00 AM New York time on the second business day after the loco London or loco Zurich redemption order date, the Trustee’s DTC account has been credited with the Baskets to be redeemed. In the event that, by 10:00 AM New York time on the second business day following the order date of a redemption order, the Trustee’s DTC account has not been credited with the total number of Shares corresponding to the total number of Baskets to be redeemed pursuant to such redemption order, the Trustee shall send to the Authorized Participant and the Custodian via fax or electronic mail message notice of such fact and the Authorized Participant shall have two business days
