Methodology

Offering announcements are company press releases that Quantisnow classifies as a public offering (launch, pricing or closing). Prospectus supplements cover Forms 424B2, 424B3 and 424B5. Shelf registrations cover S-3, S-3ASR, S-3MEF and F-3ASR. IPO registrations cover S-1 and F-1.

Counts are distinct Quantisnow wire items, bucketed by the calendar month (UTC) in which Quantisnow first received them. Each item carries one event category assigned by our parsers at ingest; an item is never counted in two categories.

Figures are recomputed daily from the Quantisnow event database. The current month is marked as month to date until it closes; the previous month is recomputed daily through the following month to pick up late filings, then stays fixed.

Definitions for every column are in the JSON download.
