It might be a good idea to get in touch with the person that your company 401K administrator is getting their information from at the investment firm that handles your companies "account", there might be some goodies in there that are not plain to see. Most employees don't know enough to care about it, so maybe there's more there than you know. Can't hurt to ask. Yeah, we know, "I'll never get that old".
