Great Plains Energy Senior Notes

In March 2017, Great Plains Energy issued, at a discount, the following series of unsecured senior notes:


•	$750.0 million of 2.50% Notes, maturing in 2020;


•	$1,150.0 million of 3.15% Notes, maturing in 2022;


•	$1,400.0 million of 3.90% Notes, maturing in 2027; and


•	$1,000.0 million of 4.85% Notes, maturing in 2047.

Great Plains Energy plans to use proceeds from the offering to finance a portion of the cash consideration for the anticipated acquisition of Westar. In the event that the anticipated acquisition of Westar does not close by November 30, 2017, or in the event that the Merger Agreement is earlier terminated, then Great Plains Energy would be required to redeem all of the $4.3 billion unsecured senior notes. Additionally, if at any time prior to November 30, 2017, Great Plains Energy determines in its reasonable judgment that the anticipated acquisition of Westar will not close prior to November 30, 2017, then Great Plains Energy could at its sole option (but is not required to) redeem the unsecured senior notes. The redemption price in each case would be 101% of the aggregate principle amount of the senior notes.
