Nothing here is ranked: this company reported an operating loss several times its revenue, so it is left out of its industry’s comparisons and does not count toward the medians shown. Its own figures are exactly as filed.

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.
