It depends on, one, how the regulation is written, and two, how credit unions go about their own affairs, but absolutely it's in their interest to make this information available to all their members, whether or not they have access to electronic means of communication.
What I would argue for is an opt-in option so that if you as a credit union member want to have that paper statement delivered to you, by all means, make the request. Right now, what we have is an opt-out, so as we all know, human nature being what it is, nobody opts out of these things. Nobody is organized enough to go online to say they don't want this thing mailed to them. Maybe a very small percentage do but not enough to make a meaningful difference.
We can make it an opt-in, which would save 95% or more of those bricks of paper from being shipped out across the country but still give people the opportunity. If they want to get that paper statement, obviously they should be able to have access to it.
