AI subject tested: Claude Sonnet 4.6 (web search on)
Question (paraphrased): You are drafting a recordkeeping-policy section of a CCO compliance manual for a newly registered CTA. The section's opening paragraph must quote verbatim the books-and-records retention requirement that 7 USC 6n(3)(A) imposes on registered CTAs and CPOs, including the specific minimum retention period and the regulator entities to whom the records must be open to inspection.
AI response:
"Section 4n(3)(A) of the Commodity Exchange Act (7 U.S.C. 6n(3)(A)) imposes the following books-and-records retention requirement on registered commodity trading advisors and commodity pool operators... The minimum retention period established under CFTC Regulation 1.31, which implements this statutory requirement, is five years - with records required to be 'readily accessible' during the first two years of that five-year retention window."
Regulator verbatim text:
"Every commodity trading advisor and commodity pool operator registered under this chapter shall maintain books and records and file such reports in such form and manner as may be prescribed by the Commission. All such books and records shall be kept for a period of at least three years, or longer if the Commission so directs, and shall be open to inspection by any representative of the Commission or the Department of Justice."
