SEC filing timeliness
What is in it
One row per filing: the company, the form, the period end, the date it reached EDGAR, and the number of days between them. Both dates are EDGAR’s own, so nothing here depends on a figure this site worked out.
What it shows
Amendments arrive months after the statements they correct. A 10-Q lands about six weeks after the quarter it reports; a 10-Q/A takes around six months, four to five times as long. Anyone treating filed data as final within a quarter is working with figures a meaningful share of which will later move.
By form
| Form | Filings | Mean days | Median days |
|---|---|---|---|
| 10-Q | 137,099 | 40.6 | 38 |
| 10-K | 44,220 | 70.7 | 61 |
| 10-Q/A | 1,762 | 186.6 | 137 |
| 10-K/A | 1,469 | 208.5 | 149 |
