What are the key compliance dates under the 2024 Regulation 1.25 amendments — specifically the general effective date for conforming investment policies and the separate deadline for updating Segregation Investment Detail Reports and customer risk disclosure statements?
The rule specifies March 31 2025 as a fixed calendar date for the SIDR and risk disclosure update deadline. The model replaced this with a relative range — "roughly six months to a year after the effective date" — which is the kind of phrasing that appears in early regulatory commentary or implementation-guidance estimates before a final compliance date is set. The model appears to have drawn on pre-final-rule secondary discussion rather than the rule's published compliance calendar, producing a response that is actively misleading for any firm calculating its deadline.
This finding implicates calibration on compliance-deadline specificity. The rule publishes a fixed calendar date (March 31 2025) for the SIDR update deadline; the model substituted a relative range drawn from pre-final-rule commentary. The retrieval pipeline either did not surface the compliance calendar from the final rule text, or the model discounted it in favour of a higher-frequency secondary framing. Post-training calibration should penalise relative-range answers on compliance deadline questions where a fixed date is retrievable from primary source.
An Internal Audit team that accepts the AI's stated timeline — six months to a year after the February 21, 2025 effective date — will build its SIDR and risk disclosure testing window around Q3–Q4 2025, bypassing a March 31, 2025 hard deadline that the CFTC set as a discrete compliance obligation. The immediate operational consequence is a missed deadline embedded undetected in the audit program, with the firm technically non-compliant while Internal Audit's own tracking shows it as on-schedule.
When the CFTC examines the firm's SIDR reporting and risk disclosure updates — both high-visibility obligations under the 2024 amendments — work papers reflecting an incorrect compliance date will compound the original breach, signalling to examiners that the audit function itself lacked accurate regulatory awareness during the implementation period. Remediation at that stage involves not only correcting the SIDR and disclosure deficiencies but reconstructing the audit trail to demonstrate when the error was introduced and what review controls failed to catch it.
Each finding has a stable Citation ID (RLB-F-… for aggregated case-study findings, RLB-H-… for raw per-model hallucinations) — like a DOI, the ID always resolves to the canonical finding even if URLs change.
