Verification log

A figure on this site is only worth citing if it can be checked, so it is checked — automatically, daily, and the results are published here rather than kept. Nothing on this page is written by hand.

What runs

Daily re-derivation. Each morning ten published funds are drawn at random (seeded by the date), their latest N-PORT filing is fetched again from SEC EDGAR, every published figure is recomputed from scratch, and the result is compared with what the site shows. A mismatch is listed below with the fields that moved. A mismatch is not always a fault: when a fund has filed a newer period since the site was built, the audit sees the new filing and reports the difference until the next data refresh.

Before every update. Three checks run and publication stops if any fails: data (every figure within its possible bounds, part never larger than whole, files consistent with one another); overlap (all 275 published pair overlaps recomputed by a second, separately written program that reads the filings itself, including the securities-lending collateral flag); and country (the country split of forty funds, the twenty-five largest and fifteen drawn at random each run, re-derived from the archived filings by a separate parser and compared with the published tables, plus the pooled quarter for the United States, Japan and Korea).

When a rule turns out to be wrong the fix is applied across the site, dated on the methodology page, and written up: see the collateral correction of 2026-09-14.
