Details
The SEC index was refreshed through October 8, 2026. Exact duplicate
rows are removed; distinct entries sharing an AAER number are retained.
Source-backed corrections retain November 16, 1999 for AAER-1209 and restore
AAER-1470 dated October 23, 2001. Historical entries missing from the current
index are preserved, including three intentionally omitted numbers with
missing dates. The malformed historical identifier AAER-x2218 is replaced
by AAER-2218. Raw snapshots, historical supplements, and the correction table
with release links are maintained in data-raw; see also
the refresh investigation.
Index dates have not all been checked against the underlying releases.
