The table above excludes the estimated fair value of CSC Holding's note payable to Captive of $82,500 and $90,500 for the years ended December 31, 2025 and 2024, as it is eliminated in the Optimum Communications' consolidated financial statements (see Note 16). The carrying value of the note payable approximates fair value due to its short-term maturity (less than one year).
