For example for one of Vanguard's funds it stated:
FTSE Developed World ex-U.K. Equity Index Fund - Accumulation (FPC9.GB) has declared a GBP 6.167605000 per share final distribution. Group 2 units will have an equalisation rate of 3.285574000 applied
This does not seem to be the same as a 'dividend' - so what is it? What terms can I search / investigate for to understand it? I didn't seem to have much luck with "share distribution".
