The Alliant Energy 401(k) holds $1.41bn. Of the $614m we could identify from the plan’s own filing, every dollar sits in a fund that publishes no record of how it voted your shares — collective trusts, which unlike a mutual fund file no Form N-PX and leave no public trace of a single vote.

Why there is nothing to show
A mutual fund has to file Form N-PX every year listing every vote it cast on your behalf. A collective investment trust does not. It is a bank-run vehicle sold only inside retirement plans, it is cheaper, and it is now where most 401(k) default money sits — including most target-date funds, which is where savers who never chose anything are put.
So the shares bought with Alliant Energy employees’ retirement savings are voted every proxy season — on executive pay, on board seats, on climate and workforce proposals — and there is no public document anywhere recording how. This is not an oversight by Alliant Energy; it is what the disclosure rules currently require, which is to say: nothing.
What you can do
Check whether your plan offers any registered fund as an alternative — those publish their records, and you can read them here. If it does not, the menu itself is the thing that has to change, and that is a decision made by the plan’s fiduciary committee, not by you alone.
