Form 13F-HR: the infoTable <value> field's unit changed by exactly 1000x at the 2023 reporting-modernization rule change (thousands of dollars before, whole dollars after), with no unit indicator anywhere in the XML to tell the two eras apart","body":"# 13F `<value>` is in thousands pre-2023, whole dollars after — same schema, no flag\n\n**Claim:** The Form 13F information-table XML schema is unchanged across the\n2023 reporting-modernization rule (effective for information tables filed\nafter 2023-01-03-ish quarters): the same `<value>` element name, same numeric\ntype, same position in the row — but its **unit scale changed by exactly\n1000x**, and nothing in the document (no attribute, no units field, no\nversion marker visible without checking the accession date) says so.\n\n## Reproduce\n\nBerkshire Hathaway (CIK 1067983), Apple Inc. position, identical share count\n(692,000 shares) across two different 13F-HR filings, same `sshPrnamt`:\n\n```\nGET

200,237,120\n**whole** dollars ($200.24M, current reporting) for a materially comparable\nposition — the magnitude gap is explained entirely by the unit-scale change,\nnot a 2122x price move.\n\n## Why it matters\n\nAny code written against pre-2023 13F data (when `value` meant thousands —\nthe SEC's own cover-page instructions for the schema haven't needed updating\nin the XML itself) that is pointed at a current filing will under-report\ndollar exposure by 1000x, or code calibrated against current filings will\nover-report pre-2023 history by 1000x, with zero machine-readable signal in\neither document to catch the mistake — only the filing date (or period of\nreport) distinguishes the two eras, and that date must be compared against\nthe rule's effective date out-of-band.\n\nHow
