Payables and Accruals [Abstract] |
Supplementary Balance Sheet Detail | Supplementary Balance Sheet Detail Supplier Finance Program (“SFP”) Obligations GrafTech Mexico S.A. De C.V. (“GrafTech Mexico”) participates in an electronic vendor voucher payment program supported by the Mexican Government through one of its national banks, whereby suppliers can factor their invoices through a financial intermediary. This program gives GrafTech Mexico’s suppliers the option to settle trade receivables by obtaining payment from the financial intermediary prior to the invoice due date for a discounted amount. GrafTech Mexico’s responsibility is limited to making payment on the terms originally negotiated with its supplier, regardless of whether the supplier elects to receive early payment. The range of payment terms GrafTech Mexico negotiates with its suppliers is consistent, irrespective of whether a supplier participates in the program. As of September 30, 2023, $7.4 million of SFP obligations were included in accounts payable on the Condensed Consolidated Balance Sheets and upon settlement, are reflected as cash flow from operating activities in the Condensed Consolidated Statements of Cash Flows. GrafTech Mexico did not have a SFP obligation as of December 31, 2022.
