Every entry is taken from the breach report NCH CORPORATION lodged with the Illinois Attorney General. Nothing here is estimated.

Why do the incident date and the report date differ?

Companies usually investigate before they report. The gap between the two dates shows how long that took.

What does the records-affected figure count?

It is the number the company gave the state. It can cover residents of that state only, so the national total may be higher.
