To quote the old Ragu commercial, it's in there. Here's an example:
We'll use $10,000 invested in the I fund and EFA etf to show that dividends are in the I fund and the expense ratio is considerably lower than at the ETF.
On Dec 29 2006 (the last business day of the year) the I fund was at $22.22. Investing $10,000 buys us 450.045 shares. At the end of 2007 each share is worth $24.76, so our stake is worth $11,143.11. We had a nice year with an 11.4% return.
The EFA ended 2006 with a value of $73.22, our $10,000 buys 136.575 shares, to those playing along at home, I realize you can't buy a partial share of an ETF, but didn't want to consider that when focusing on dividends and admin costs. The EFA pays a single annual dividend, $2 in 2007, paid on Dec 21, this buys us an extra 3.476 shares. Thus, we end the year with 140.051 shares which each have a value of $78.50. Our EFA infestment is worth a total of 10993.99. Still a nice return of 9.9% for the year. The difference comes from the ETF at a premium to NAV at the beginning of the year (NAV was 72.95 so you were paying extra vs an open ended fund), but at a discount at the end of the year (NAV was 78.92). On a NAV basis, there's an extra 1% so the return was 10.9%, the difference being attributatble to about 30 bp of extra management fees, and the single dividend payment that occured was reinvested at a relatively high NAV rather than as payments occured.
