What Happened

Context
These entries reflect a structural conversion of Class B to Class A shares and internal fund/member distributions rather than market trading. For retail investors, conversions and in‑kind distributions by a fund generally do not signal a market sale by the fund manager; they represent reclassification and redistribution within the fund and its members. Because this is a 10% institutional holder, the filing documents fund mechanics more than executive sentiment.
