Context

• This appears to be a routine settlement of vested performance awards with a sell-to-cover for taxes rather than an open-market sell reflecting a directional view. The M-coded entries reflect conversion/exercise of award units into common shares; the F-coded sale is the customary tax withholding mechanism. These kinds of filings are common when time-based or performance-based awards vest.
