*~*~*

Mark A. Ruelle - Westar Energy, Inc. - CEO, President & Director

So these are just a handful of accomplishments of our employees as we move our business forward even as we look to merging, and it is to deliver greater value for our customers and to grow the value of your investment as shareholders. As I’m sure you all know, Westar and Great Plains Energy announced in July an amended agreement under which we plan to combine, not by being acquired by Great Plains Energy but by merging side-by-side in a stock-for-stock merger of equals. Additionally, and with the valuable advantage not present in the first agreement, this exchange will be tax-free to shareholders. I’m delighted to add that it also means a 15% increase in the common dividend for Westar’s shareholders. And we structured the transactions to specifically address the demands that regulators put on us when we merge.

The rationale for the merger remains consistent with what you heard from us before, that is geographic fit with our next-door neighbor, complementary operations including the joint operations and ownership of big power plants, similar computing platforms and regulatory diversity across 2 states. And most importantly, the ability to create operating efficiencies will help to keep our costs under control to keep electricity affordable for our customers and to assure good returns for our shareholders.

Additionally, as I mentioned, it provides for an immediate 15% increase in the dividend at closing. And thereafter, we’ll target dividend growth, higher than what we could have targeted without the merger.


We’re continuing through the process with regulators and with you as shareholders. To that end, we scheduled a special shareholder meeting next month right here, on November 21, where we’ll ask you to vote for the merger and the related proposals. You should have already received a proxy for that special meeting. And if you haven’t yet submitted your proxy for that special meeting, I encourage you to do so in advance of the November 21 meeting, and ask that you please vote for the merger. Your vote on that is really important because the way votes are counted if shareholders don’t vote, that gets counted the same as voting against the merger and effectively, against the higher dividend that comes with the merger. So if you have any questions about the meeting or the vote that’s coming up next month, please visit with me after the meeting or one of my colleagues, or contact our Investor Relations folks and they will answer any questions you might have.

Now this is one of my favorite parts of our annual meeting, we’ll do our very best to answer any questions that you might have. If I can’t answer them and there’s a good chance I won’t be able to, I’ve got a great team of colleagues here that will help me out. And we would be pleased to try to address any of your questions. If you just raise your hand, we’ll bring a microphone to so that other folks can hear your question as well. Thank you.

QUESTIONS AND ANSWERS

Shareholder: My question is in looking over the proposal for the merger that you have opinions, both Great Plains and Westar, of your accounting firms or the people you have hired — engaged to render an opinion on the tax-free exchange basis. But I also saw on both sides there was a disclaimer that maybe the IRS would rule against it. Could you set that concern at ease?

Mark A. Ruelle - Westar Energy, Inc. - CEO, President & Director

I think so. But I might lean on our General Counsel or our Controller, to clarify it. As you know, regulations are complex. So there’s a lot of times you got to put language in there that says, there might be some obscure thing that nobody has ever thought of that would be problematic. What I can tell you is, we have negotiated and structured this transaction to make it tax-free for shareholders as they exchange one share in the old company for a share in the new company in a very customary and typical fashion for tax-free exchanges. Larry, where is Larry? Larry, do you have anything to add? Larry is our General Counsel.

Larry D. Irick - Westar Energy, Inc. - VP, General Counsel & Corporate Secretary

I think you covered it correctly. I mean, folks expressing opinions like that always want to hedge for that {Larry – can you turn around so the shareholder can hear you?} Experts when they give an opinion always want to hedge based on a totally unexpected circumstance. So I think Mark is correct in saying that this transaction is structured in a very typical way and in a way where almost in all circumstances, the tax-free nature of the transaction is recognized. So I would view that as a very remote possibility.

Mark A. Ruelle - Westar Energy, Inc. - CEO, President & Director

But just in the normal course, obviously, we would encourage you to visit ….

Shareholder: If it happens it costs the shareholders. I mean, because obviously you have to pay for the higher cost — I mean, the higher sales basis versus your cost.


Larry D. Irick - Westar Energy, Inc. - VP, General Counsel & Corporate Secretary

And then that moves back to the nature of the first transaction where the...

Shareholder: Well, we already knew about that.

Larry D. Irick - Westar Energy, Inc. - VP, General Counsel & Corporate Secretary

You knew about that.

Mark A. Ruelle - Westar Energy, Inc. - CEO, President & Director

This is specifically designed to address that concern that people had with the first transaction to make it tax-free. But as Larry said, we live in a world that’s very litigious. So we would obviously encourage you to visit with your tax adviser, your accountant if you have any concerns about this. But we would not be telling you we’ve structured it to be tax-free if we didn’t have a high level of certainty that, that’s the case.

Shareholder: However, your professional opinions were rendered with that qualification.

Mark A. Ruelle - Westar Energy, Inc. - CEO, President & Director

As they always are. If you have dealt with an engineer, an accountant or a lawyer, you’ve seen those before. Just wait until you try to build a foundation sometime and see what kind of engineering qualifications you get. Thanks for your question. Are there other questions? Comments? In the back. Sorry Bruce.

We will come back to Bruce.

Shareholder: When you guys do this, it’s like 5 years. And in your merger here, how many jobs will be lost from Topeka area? And like will this building be half full or is your headquarters going to be in Kansas City? A lot of duplications, a lot of people will be getting laid off, what do you think or how are you working all that out? Just going on, probably they will be retiring a lot of people and then that’s how it’s going to justify that, I guess?

Mark A. Ruelle - Westar Energy, Inc. - CEO, President & Director

So the building won’t be half full. We’ll continue to have a Kansas operating headquarters right here downtown Topeka. And we’ve said that we will have at least 500 people in the headquarters. Today, we have between 500 and 600 people in this headquarters. You are correct that combining the two companies will mean that we can save costs and one of our largest costs is, in fact, the cost of professionals and you’re also correct that there is some duplication. But the reason we can reduce costs and reduce the level of employment without having to lay anybody off is because we have so many people in our industry that frankly, are aging baby boomers. Folks that are naturally wanting to retire anyway. So as we speak, both companies, Great Plains Energy and Westar have held open vacant positions, hundreds of vacant positions, temporarily filling them with contractors or baling wire or duct tape in anticipation of closing so that we can bring those efficiencies without having to put somebody on the street losing their job. But indeed, the combined company will have fewer employees than the sum of the parts prior to the merger. And it’s always the balance of keeping our electricity affordable and making sure that we continue to be great employers and good citizens. Thanks for your question.


Shareholder: With that said, and with you talking about the fact that Westar has made great strides in wind energy over the last 5 years, what about your future partner, Great Plains? They were the last company to spend a whole bunch of money on a coal plant. What strides have they made to go to renewable energy, particularly knowing they can’t get transmission lines through part of the state?

Mark A. Ruelle - Westar Energy, Inc. - CEO, President & Director

Yes. Their profile is very much like ours. What you said is correct. While we recently reinvested in a lot of our larger coal plants, they built one just a few years ago. But they have added a similar complement of renewable energy, almost all of it right here in Kansas. And in fact, the profile I gave, which was about 1/3 renewable and about little over half without any emissions, the new company will be very similar to that. We have just a couple hundred megawatts more renewables than they do today and we’re about the same size.

Are there any other questions? If not, thank you very much for coming today and for getting an update on your company. We thank you for your trust and your confidence and your investment. And for taking the time to be here. We also encourage you to look in your mail to make sure you see the proxy for the special meeting coming up and then please send in your vote. Thank you very much.
