Flows (revenues, income, cash, distributions, repurchases) are shown for the period the issuer reported them in, which may be a quarter, a year-to-date span or a full year; “a year earlier” compares only periods of the same length. A vehicle that does not tag a figure in XBRL will not show it here even if the PDF discloses it.

No forensic read of this vehicle yet. When a filing changes something for holders — a tender offer, a repurchase cap, a NAV reset, a distribution cut — the read goes here.
