Each report’s comparison uses the figures it filed for the same period a year earlier, for up to its newest 16 reports. A figure is left out when the filing has no matching period. The notes on each row are general guides written by hand, not a reading of that filing. Open a 10-K, 10-Q, 8-K or Form 4 for a reading of that one filing, written by code from its own fields.
