Insights

Compliance Analyst

Restatement documents quantitative errors and four concrete root causes; remediation and disclosure completed.

The filing lists a corrected 13F Information Table with 269 entries and aggregate market value of $786,393,853, and it explicitly names two other included managers.

Remediation appears to be internal reconciliation and reporting via an amendment; subsequent filings or disclosures may show implementation details and validation steps.

Data Controls Specialist

Errors stem from spreadsheet logic, rounding rule non‑implementation, and account omissions; these are common control failures.

The filing cites an XLOOKUP vs SUMIF misuse, Excel scientific‑notation conversion, and missed market‑making accounts across multiple quarters, which imply systemic data‑aggregation risk.

Recommended follow‑up items in filings would include validation of automated reconciliations and proof of corrected procedures; timing and verification steps are not included in the excerpt.

During an internal review of StoneX Group Inc.'s Section 13(f) reporting practices we discovered the quarterly filings from Q4 2021 through Q1 2025 under-reported the total number of securities, shares and market values. The errors involved all Other Reporting Managers: StoneX Advisors Inc., StoneX Financial Inc., and Trust Advisory Group, Ltd. The review identified four main causes: 1. Missing Market Making Accounts; Between Q4 2021 and Q4 2024, three market making accounts were inadvertently excluded from the Firm's filings. 2. Formula Error in Excel; From Q1 2022 to Q4 2022, the Firm mistakenly used "XLOOKUP" functionality instead of "SUMIF" in Excel causing only the first instance of a CUSIP to be counted. 3. Failure to Implement Rule Change; SEC Rule 87 FR 38943 requiring all dollar values to be rounded to the nearest dollar, rather than to the nearest one thousand dollars, was not properly implemented from Q4 2022 to Q1 2025. 4. Excel Scientific Notation Error; Between Q4 2021 and Q1 2025, CUSIPs with an "E" were inadvertently converted into scientific notation in Excel. This led to the misidentification of certain reportable securities.
