Two standard screens, computed from the XBRL in FY2025 against FY2024. Every test shows the numbers behind it — a score with its inputs hidden is a number you cannot check.
Bankruptcy-risk screen combining working capital, retained earnings, operating income, market value against liabilities, and asset turnover. Above 2.99 is the safe zone; below 1.81 is distress.

From 13F filings, which cover institutions managing over $100m and are filed up to 45 days after the quarter ends — so this is a considered position, not a live one, and it is not the whole shareholder register. These filings span 2024-Q2–2026-Q2 rather than a single quarter, because filers report on their own schedules.
What the company actually paid out and bought back, as reported — the record behind any yield figure.
Ownership percentages are a vendor aggregate, not a filing — unlike everything else on this page.
Companies filing in the same SEC industry group.
The structure map above is the Corporate Blueprint, and in the desktop it is interactive — click any entity to re-centre the map on it and walk the ownership chain. It sits alongside the screener, the scorecard and the filings lab on one desk, on your machine.
Sourced from SEC EDGAR primary filings. Figures are as reported by the company and are not investment advice. Scores are standard published screens computed from those filings; every input is shown above so you can check the arithmetic.
