all SEC 10-K Item 1C
Earliest sighting first · deep chronology in Litigation Timeline
The Charles Schwab Corporation's 10-K Item 1C cybersecurity disclosure describes the company's general cybersecurity risk management framework, governance structure led by a CISO reporting to the Chief Technology, Operations and Data Officer, and notes that prior cybersecurity events have not been material to the company's strategy, results of operations, or financial condition. No specific breach incident is disclosed.
About this clustering
DisclosureLens links filings into incidents through layered matchers: deterministic rules (same source document, multistate filings of one breach, tight-window same-victim pairs), a weighted-similarity scorer for cross-source candidates, and an operator review queue for everything uncertain. Each link records its own method and confidence — shown per filing in the timeline below. The system defaults to NOT merging when uncertain, because a false merge (collapsing two unrelated breaches) is more harmful than a false split (showing related filings separately); uncertain pairs route to human review instead of auto-merging. Filing summaries shown in the timeline are AI-generated extracts — verify each against its linked source.
