Yes, they are nuisance fees to discourage short term trading and to minimize fund costs. If you hold these funds for the long term, those folks who trade more often will pay more fees into the fund which helps you. Anyway it's a lot better than paying a ~5% load and hopefully the fee % will eventually decrease or disappear altogether.
VEIEX:
The fund assesses a 0.5% fee ($5 per $1,000 invested) on purchases and redemptions. The fee is paid directly to the fund and therefore is not a load.
VFWIX:
The fund assesses a 0.25% fee ($2.50 per $1,000 invested) on purchases. The fund charges a 2% fee ($20 per $1,000 invested) on shares redeemed within two months of purchase. The fee is paid directly to the fund and therefore is not a load.
