    "title": "A record-date holding and an event amendment must refer to the same security",

    "answer": "CC1 identifies E1R as the amended S-A event with day 10 as its record date. CC2's S-A day-10 card, six synthetic units, matches that security and date; the day-9 card and S-B's similar label do not. CC3 establishes an acknowledgment but leaves entitlement, allocation and payment unverified. Assemble the matched documents for review without treating the event notice or holding match as a completed distribution.",
