Fair Value of Debt Instruments As of June 30, 2026 and December 31, 2025, the fair value of BNSF’s debt, excluding finance leases, was $21.3 billion and $22.1 billion, respectively, while the book value as of June 30, 2026 and December 31, 2025, which also excludes finance leases, was $23.5 billion and $24.0 billion, respectively. The fair value of BNSF’s debt is primarily based on market value price models using observable market-based data for the same or similar issues, or on the estimated rates that would be offered to BNSF for debt of the same remaining maturities (Level 2 inputs).
