    "The April top-20 list is not a complete current beneficial ownership register. Some entries are nominees, custodians, or reported group aggregates; they may overlap with substantial-holder rows.",
    "The historical April table contains the issuer’s original label State Sreet Corporation. Registered ownership, beneficial ownership, voting interests and investment-management interests should not be summed.",
    "Scanned Kopernik notices through 19 October were visually inspected. The earlier 21 September, 19 August, 5 August, 22 July and 12 June notices concern the same manager and are superseded by its 15 October figure.",
    "The O’Keeffe notice gives a 5 August change date but also records sales on 6 August, and describes the quoted total as after those sales. Its post-sale quantity is dated to 6 August with this internal inconsistency disclosed.",
    "The issuer’s April top-20 combines registered nominee accounts and named manager or group interests using multiple sources; it is not a pure legal-holder register and these amounts may overlap.",
    "The dated disclosures do not establish current beneficial ownership or complete global shareholder coverage. Positions can change without a new filing."
