Insights

Securities Analyst

TL;DR Routine director equity accrual converted to shares; transaction appears non-material and does not indicate insider selling.

The reported per-share amount is $147.17 and beneficial ownership after the event is 25,772.524 shares (direct). This type of entry typically reflects settlement of deferred compensation rather than open-market trading and, based on the reported size, is unlikely to be material to Owens Corning's capital structure.
