The \"F\" suffix identified filings by registered open-end management investment companies and unit investment trusts that had elected indefinite registration of securities under Section 24(f) of the Investment Company Act of 1940 and Rule 24f-2 thereunder. The submission type was discontinued in January 1998 when amendments to Rule 24f-2 made indefinite registration automatic, eliminating the need for a separate election-based form variant. The dataset includes all Form 485BXTF filings submitted to EDGAR from August 1997 until the form was discontinued in January 1998. For each accession number, a metadata file and all documents in the original EDGAR submission are included except image files. Each filing typically contains a cover page identifying the registrant and the prior post-effective amendment being redesignated, the newly designated effective date, signatures of authorized officers, and any required exhibits supporting the redesignation under Rule 485(b)(1)(iii).","updatedAt":"2026-04-16T09:04:56.443Z","earliestSampleDate":"1997-08-01","totalRecords":1,"totalSize":3591,"formTypes":["485BXTF"],"containerFormat":"ZIP","fileTypes":["TXT","JSON"],"containers":[{"downloadUrl":"https://api.sec-api.io/datasets/form-485bxtf-files/1997/1997-08.zip","key":"1997/1997-08.zip","size":3591,"records":1,"updatedAt":"2026-04-16T09:04:56.443Z"}]}
