What changed?
Source-backed comparisonsNo differences were found in the comparable fields and periods reviewed. This does not establish that the business was unchanged.
Coverage and interpretation
0 adjacent monthly snapshot pairs reviewed; archive through Sep 2026. 1 comparable leadership filing pairs through Jul 15, 2026.
Changes reflect reported values and selected leadership records. Snapshot months are not event or valuation dates. Missing months and incomparable values are excluded. AUM changes are not investment returns or organic growth; filing differences do not establish hires, departures, acquisitions or their effective dates.
Growth and background
History through Sep 2026Reported regulatory AUM change was Unavailable in 2025, the last full calendar year. The average annual change over the preceding five years (2020–2024) was Unavailable.
Snapshot changes, not investment returns or organic growth. YTD is not annualized.
Calculation and source values
Annual growth = (December AUM ÷ prior December AUM − 1) × 100. The benchmark is the arithmetic mean of the five years before 2025. The difference is in percentage points (pp). YTD compares the latest source month with the preceding December. Source months are not valuation dates.
Only exact months with comparable reported regulatory AUM qualify. A missing or flagged value, a definition change, or zero starting AUM makes that comparison unavailable.
