Insights

Securities compliance analyst

Routine Form 4 via DRIP; neutral for valuation.

The transactions are automated dividend reinvestments, coded J, which are exempt under Rule 16a-11. This indicates shares were purchased through a plan rather than discretionary open-market buys.

Two reinvestments occurred at $65.17 and $63.75, modestly increasing beneficial ownership. Such filings typically do not alter the investment thesis.
