This does describe what I'm seeing - that an extra "income" dividend is paid at the end of the year, and that it doesn't vary by share class (since all the expenses have been paid already out of the usual monthly dividends).
What puzzles me about that M* statement (which likely reflects reality, at least in part), is that I don't see anything in the prospectus about the fund being an ersatz managed payout fund and that I can't get the financials to match.
Specifically, the fund's net investment income per share comes out to less than the total monthly income dividends (per share) paid out, let alone the total income dividends (including the year end "bonus"). How does it do this without return of capital?
This is based on the
prospectus' Financial Highlights. (That's a 38MB file; just in case you've got thoughts of actually checking up on me :-) ) Wait for it to load so that it jumps to Financial Highlights, then scroll a few pages, past prospectus p. 87, to p. 89 where you'll find the data for PIMCO Income Fund.
It shows for the year ending 3/31/1
5 that the fund distributed 74c as income (for PONDX, i.e. Class D). This matches the sum of the monthly income dividends between April 2014 and March 201
5 plus the bonus dividend on 12/29/14 of 10.6c, give or take rounding to the nearest penny.
But that same line in the prospectus says that the net income per share for the same period was only 49c. Where did that other 2
5c/share come from? The prospectus says there was no return of capital.
I honestly don't have a clue; I don't usually try to dissect financials this finely. There's more going on; can't really comment more on it without understanding it better. Homework for another day, perhaps.
