If my fund is NOT on the list, what happens?
1. All Vanguard is DRIP eligable. If its not on your banks list is because they havent updated the list. Call the bank to confirm. They can only set up a DRIP in your account after you own the fund.
2. The thresholds are not a "rule", per say. They are a calculation based on the current dividend and unit price.
ie, i own 10 units. The January Dividend was $0.10 per unit. Thus I get $1.00 in divedends a couple weeks after the dividend date. If im not in DRIP, it shows up Feb 15 as $1.00 cash in my account and I need to spend $9.95 to reinvest it. Boo!
If im in DRIP and the unit price is $0.98, my DRIP gives me one more unit and I then own 11. It also gives me $0.02 cash. Yeah!
However, if the unit price is $1.09, then my dividend does have enough to buy another unit and i get $1.00 cash. Boo! I should have bought 11 units in December.
Clear as mud?
Dont forget some funds have quarterly distributions that are much smaller per unit than funds that have annual distributions.
AFAIK, you are responsible to figure these limits out before you get into ETFs. This is why couch potato doesn't advocate ETFs for small accounts.
