Could not find a ticker for this position, may be a filing error
A holding company whose chief asset is a large ownership stake in Charter Communications, the cable and broadband operator serving millions of American homes under the Spectrum brand. It began in 2014 when media mogul John Malone spun communications assets out of his Liberty Media empire. In 2025 it spun off its Alaska telecom GCI and agreed to be absorbed by Charter in an all-stock deal, folding back into the business it was built around.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 5 years: -514.1K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
