(4) Assets and Liabilities Measured at Fair Value

For assets and liabilities required to be reported at fair value, GAAP provides a hierarchy that prioritizes inputs to valuation techniques used to measure fair value into three broad levels. Level 1 inputs are quoted market prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 inputs are inputs, other than quoted market prices included within Level 1, that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. The Company does not have any recurring assets or liabilities measured at fair value that would be considered Level 3.

The Company’s assets and (liabilities) measured at fair value are as follows:

Pursuant to an indemnification agreement initially entered into by GCI Liberty and assumed by Liberty Broadband in connection with the Combination,  Liberty Broadband has agreed to indemnify Liberty Interactive LLC (“LI LLC”), a subsidiary of Qurate Retail, for certain payments made to holders of LI LLC’s 1.75% exchangeable debentures due 2046 (the "LI LLC 1.75% Exchangeable Debentures"). An indemnity obligation in the amount of $336.1 million was recorded upon completion of the Combination. The indemnification liability due to LI LLC pertains to the holders’ ability to exercise their exchange right according to the terms of the LI LLC 1.75% Exchangeable Debentures on or before October 5, 2023. Such amount will equal the difference between the exchange value and par value of the LI LLC 1.75% Exchangeable Debentures at the time the exchange occurs. The indemnification obligation recorded in the condensed consolidated balance sheets as of September 30, 2021 represents the fair value of the estimated exchange feature included in the LI LLC 1.75% Exchangeable Debentures primarily based on observable market data as significant inputs (Level 2). As of September 30, 2021, a holder of the LI LLC 1.75% Exchangeable Debentures has the ability to exchange and, accordingly, such indemnification obligation is included as a current liability in the Company’s condensed consolidated balance sheets.

The Company’s exchangeable senior debentures are debt instruments with quoted market value prices that are not considered to be traded on “active markets”, as defined in GAAP, and are reported in the foregoing table as Level 2 fair value.

Other Financial Instruments

Other financial instruments not measured at fair value on a recurring basis include trade receivables, trade payables, accrued and other current liabilities, current portion of debt (with the exception of the 1.75% Debentures (defined in note 7))

and long-term debt (with the exception of the 1.25% Debentures and the 2.75% Debentures (defined in note 7)). With the exception of long-term debt, the carrying amount approximates fair value due to the short maturity of these instruments as reported on our condensed consolidated balance sheets. The carrying value of our long-term debt bears interest at a variable rate and therefore is also considered to approximate fair value.

Realized and Unrealized Gains (Losses) on Financial Instruments

Realized and unrealized gains (losses) on financial instruments are comprised of changes in the fair value of the following:
