All 35 lines
From the debt note in the 10-K's XBRL (0000352541-26-000007), as the company tags it: by issue, by year, by currency or by kind. Lines from two ways of cutting the same debt can overlap, so they are not added up. Fixed or floating is read from the line's own name only; "not stated" when it says neither.
Left: the debt lines on the balance sheet (XBRL). Right: the principal due each year, from the debt note's maturity schedule; it can differ a little from the balance sheet, which shows the debt net of discounts and fees. Leases are not counted.
When LNT has to repay the principal of its long-term debt, from the debt note of the 10-K filed Feb 20, 2026 (balance sheet of Dec 31, 2025). Fiscal years are counted from that date.
