Today, interest on cash increased to 0.35% p.a. for VIAC vested benefits (0.6% p.a. for VIAC 3a). They have yet to update their webpage, though.
Also, the total fees are now capped at 0.40% instead of 0.44% (this doesn’t include extra fees for certain funds).

As far as I know, VIAC only has a single foundation for vested benefits, which means you can’t have multiple accounts. finpension allows two accounts (two foundations). Combining VIAC and finpension is also possible, of course.
