Context
This was a derivative award tied to deferred stock units (DSUs), not an open-market purchase or sale. Dividend-equivalent rights simply track dividends on DSUs and convert to the economic equivalent of shares as they vest — they do not necessarily indicate the insider bought or sold company stock for personal investment reasons.
