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.

Six-year record

Ownership flow

14 institutions tracked — 6 added, 7 reduced, 1 opened a new position, 1 sold out. Active managers added 7,550,285 shares while index money cut 516,497.

NORGES BANK holds a position with no prior filing to compare against, so its change is unknown rather than zero — and it is left out of the totals above.

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.

Capital returned

What the company actually paid out and bought back, as reported — the record behind any yield figure.
