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.
