“Not reported” means the company did not tag this figure in its filing, not that the value is zero. Rankings are hidden where fewer than 5 classified peers reported the metric, and compare against a broad industry code rather than close competitors.

Insider activity
Trades reported by officers, directors and 10% shareholders on SEC Form 4. None of the last 23 reported transactions were open-market purchases — grants, option exercises and sales make up the majority of insider filings at most companies.

A dash under price or value means none was reported, which is normal for grants and gifts — it does not mean the shares were free. Option exercises and awards are compensation arriving on a schedule, not a judgement about the stock.

A dash means the figure was not tagged in that year’s filing. It does not mean zero. Figures reflect the most recent filing covering each period, so restated years show their restated values.
n/c marks per-share figures that are not comparable. Companies report each year as their filings stated it, and an annual report restates only its two prior years — so after a stock split, older years remain on the pre-split share count. Totals above are unaffected.
