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.

In July 2017, as a result of the Amended Merger Agreement, Great Plains Energy determined in its reasonable judgment that the acquisition of Westar would not close prior to November 30, 2017 and exercised its special optional redemption right to redeem each series of the senior notes issued in March 2017. The redemption price was equal to 101% of the principle amount of the senior notes, including accrued and unpaid interest, for a total redemption cost of $4,400.1 million. As a result of the redemption, Great Plains Energy will record a loss on extinguishment of debt of approximately $83 million in the third quarter of 2017.
