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.
