The request usually arrives as a list: for a sample of accounts, show the basis for the allocation, when it was decided, what information was considered, and who reviewed it. Policies describe what should happen; the examiner wants evidence of what did.
Quantitative evidence answers a narrow part of that request, but it is the part that is hardest to produce internally: a dated measurement of what the portfolio's characteristics actually were, with the method written down. A factor exposure report from the quarter in question, with its methodology appendix and its data date, is a contemporaneous record. A spreadsheet built the week before the examination is not.
The same logic applies to marketing. A claim that the firm "applies a disciplined factor framework" is a statement of material fact in an advertisement; under Rule 206(4)-1(a)(2) the adviser must have a reasonable basis for believing it can substantiate the statement upon demand, and Rule 204-2(a)(16) requires the records supporting performance claims to be kept. A dated measurement with the method attached is evidence for the loading it measures; it does not by itself prove that a process was followed. Every Marnello deliverable closes with its methodology appendix and document details. We are not a compliance service and this is not legal advice.
