Debt Disclosure [Abstract] |
SHORT-TERM BORROWINGS AND SHORT-TERM BANK LINES OF CREDIT | SHORT-TERM BORROWINGS AND SHORT-TERM BANK LINES OF CREDIT Evergy's $2.5 billion master credit facility expires in 2023. Evergy, Evergy Kansas Central, Evergy Metro and Evergy Missouri West have borrowing capacity under the master credit facility with specific sublimits for each borrower. These sublimits can be unilaterally adjusted by Evergy for each borrower provided the sublimits remain within minimum and maximum sublimits as specified in the facility. A default by any borrower under the facility or one of its significant subsidiaries on other indebtedness totaling more than $100.0 million constitutes a default by that borrower under the facility. Under the terms of this facility, each of Evergy, Evergy Kansas Central, Evergy Metro and Evergy Missouri West is required to maintain a total indebtedness to total capitalization ratio, as defined in the facility, of not greater than 0.65 to 1.00 at all times. As of December 31, 2020, Evergy, Evergy Kansas Central, Evergy Metro and Evergy Missouri West were in compliance with this covenant. The following table summarizes the committed credit facilities (excluding receivable sale facilities discussed in Note 4) available to the Evergy Companies as of December 31, 2020 and 2019.
