September 2013 Investor Presentation Appendix 39

September 2013 Investor Presentation Gross margin is a financial measure that is not calculated in accordance with generally accepted accounting principles (GAAP). Gross margin, as used by Great Plains Energy, is defined as operating revenues less fuel, purchased power and transmission of electricity by others. The Company’s expense for fuel, purchased power and transmission of electricity by others, offset by wholesale sales margin, is subject to recovery through cost adjustment mechanisms, except for KCP&L’s Missouri retail operations. As a result, operating revenues increase or decrease in relation to a significant portion of these expenses. Management believes that gross margin provides a more meaningful basis for evaluating the Electric Utility segment’s operations across periods than operating revenues because gross margin excludes the revenue effect of fluctuations in these expenses. Gross margin is used internally to measure performance against budget and in reports for management and the Board of Directors. The Company’s definition of gross margin may differ from similar terms used by other companies. A reconciliation to GAAP operating revenues is provided in the table above.

September 2013 Investor Presentation Credit Metric Reconciliation to GAAP 1 Last twelve months (LTM) as of June 30, 2013 41 Funds from operations (FFO) to adjusted debt is a financial measure that is not calculated in accordance with generally accepted accounting principles (GAAP). FFO to adjusted debt, as used by Great Plains Energy, is defined in accordance with Standard & Poor’s methodology used for calculating FFO to debt. The numerator of the ratio is defined as net cash from operating activities (GAAP) plus non-GAAP adjustments related to operating leases, hybrid securities, post-retirement benefit obligations, capitalized interest, power purchase agreements, asset retirement obligations, changes in working capital and decommissioning fund contributions. The denominator of the ratio is defined as the sum of debt balances (GAAP) plus non-GAAP adjustments related to some of the same items adjusted for in the numerator and other adjustments related to securitized receivables and accrued interest. Management believes that FFO to adjusted debt provides a meaningful way to better understand the Company’s credit profile. FFO to adjusted debt is used internally to help evaluate the possibility of a change in the Company’s credit rating. 2010 2011 2012 LTM1 Funds from operations Net cash from operating activities 552.1$ 443.0$ 663.8$ 673.9$ Adjustments to reconcile net cash from operating activities to FFO: Operating leases 8.7 11.1 10.8 11.6 Intermediate hybrids reported as debt 28.8 28.8 7.2 Intermediate hybrids reported as equity (0.8) (0.8) (0.8) (0.8) Post-retirement benefit obligations 24.4 65.3 25.7 25.7 Capitalized interest (28.5) (5.8) (5.3) (7.2) Power purchase agreements 8.3 1.6 7.8 8.4 Asset retirement obligations (7.0) (6.6) (4.8) (4.8) Reclassification of working-capital changes 95.1 (0.8) 5.0 31.4 US decommissioning fund contributions (3.7) (3.4) (3.3) (3.3) Total adjustments 125.3 89.4 42.3 61.0 Funds from operations 677.4$ 532.4$ 706.1$ 734.9$ Adjusted Debt Notes payable 9.5$ 22.0$ 12.0$ 6.0$ Collateralized note payable 95.0 95.0 174.0 175.0 Commercial paper 263.5 267.0 530.1 385.0 Current maturities of long-term debt 485.7 801.4 263.1 257.1 Long-term Debt 2,942.7 2,742.3 2,756.8 3,165.9 Total debt 3,796.4 3,927.7 3,736.0 3,989.0 Adjustments to reconcile total debt to adjusted debt: Trade receivables sold or securitized Operating leases 142.5 127.2 127.4 133.9 Intermediate hybrids reported as debt (287.5) (287.5) Intermediate hybrids reported as equity 19.5 19.5 19.5 19.5 Post-retirement benefit obligations 280.5 303.1 364.2 364.2 Accrued interest not included in reported debt 75.4 76.9 41.5 62.0 Power purchase agreements 19.6 105.8 129.5 134.1 Asset retirement obligations 41.1 40.4 37.1 37.1 Total adjustments 291.1 385.4 719.2 750.8 Adjusted Debt 4,087.5$ 4,313.1$ 4,455.2$ 4,739.8$ FFO / Adjusted Debt 16.6% 12.3% 15.8% 15.5% Funds from Operations (FFO) / Adjusted Debt

FFO interest coverage, as used by Great Plains Energy, is defined in accordance with Standard & Poor’s methodology used for calculating FFO interest coverage. The numerator of the ratio is defined as net cash from operating activities (GAAP) plus non-GAAP adjustments related to operating leases, hybrid securities, post-retirement benefit obligations, capitalized interest, power purchase agreements, asset retirement obligations, changes in working capital and decommissioning fund contributions plus adjusted interest expense (non-GAAP). The denominator of the ratio, adjusted interest expense, is defined as interest charges (GAAP) plus non-GAAP adjustments related to some of the same items adjusted for in the numerator and other adjustments needed to match Standard & Poor’s calculation. Management believes that FFO interest coverage provides a meaningful way to better understand the Company’s credit profile.
