Bond ETFs usually make monthly dividend payments. The ETF manager receives quarterly or semiannual coupons on the underlying bonds in the ETF. What is the time delay between the coupons received and the monthly dividends?
I.e. Are coupons received in quarter x, and then distributed over 3 months in quarter x + 1 (or for semiannual bonds H1 and then distributed over 6 months in H2)? What about situations where coupons from different bonds are received at various points in the quarter, what happens then...are they paid out in the same month?
Would be extra grateful if you could cite the source for your information. Been looking for a resource or PDF that explains this stuff.
