The communication below will be sent on or about May 10, 2017 to certain employees of the company:
With our Annual Meeting approaching on May 23, 2017, I’m writing to remind you to review our 2017 proxy statement, vote your shares, and encourage those who you supervise to do the same. As you may know, voting among employee shareowners has historically been low. But it is critical to our continued success that our employees participate in the governance process, and make their voices heard.
As usual, there are truly important matters up for consideration. In addition to the election of four members of our Board of Directors and several routine items, we will also be voting on a shareowner proposal from the Office of Comptroller of the City of New York. Listed as Proposal 5 in the proxy statement, the Comptroller’s proposal asks us to prepare a report on political contributions that we view as unnecessary and potentially harmful. I’m encouraging employee shareowners to vote “AGAINST” Proposal 5 because:

• | We already prepare all legally required reports on political contributions

• | Your board already oversees all political activities

• | Extra reports create extra costs

• | Disclosure could expose your company to competitive harm

We welcome everyone to join us in person at the Annual Meeting, but the most convenient way for employee shareowners to vote is to do so in advance by returning their proxy card, voting online at alliantenergy.com/eproxy, or over the phone at 1-866-883-3382.
