(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's assets and liabilities measured at fair value are as follows:

​

​

The majority of the Company's Level 2 financial assets and liabilities are primarily debt instruments with quoted market prices that are not considered to be traded on "active markets," as defined in GAAP. The fair values for such instruments are derived from a typical model using observable market data as the significant inputs.

The indemnification asset relates to GCI Liberty’s agreement to indemnify Liberty Interactive LLC (“LI LLC”) and pertains to the ability of holders of LI LLC’s 1.75% exchangeable debentures due 2046 (the “1.75% Exchangeable Debentures”) to exercise their exchange right according to the terms of the debentures on or before October 5, 2023.  Such amount will equal the difference between the exchange value and par value of the 1.75% Exchangeable Debentures at the time the exchange occurs.  The indemnification asset recorded in the condensed consolidated balance sheets as of June 30, 2020 represents the fair value of the estimated exchange feature included in the 1.75% Exchangeable Debentures primarily based on market observable inputs (Level 2).  As of June 30, 2020, a holder of the 1.75% Exchangeable Debentures has the ability to exchange and, accordingly, such indemnification asset is included as a current asset in our condensed consolidated balance sheet as of that date.

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:

​

​

The Company has elected to account for its exchangeable debt using the fair value option. Changes in the fair value of the exchangeable senior debentures recognized in the condensed consolidated statement of operations are primarily due to market factors primarily driven by changes in the fair value of the underlying shares into which the debt is exchangeable. The Company isolates the portion of the unrealized gain (loss) attributable to the change in the instrument specific credit risk and recognizes such amount in other comprehensive earnings (loss).  The change in the fair value of the exchangeable senior debentures attributable to changes in the instrument specific credit risk was a loss of $90 million and a gain of $10 million for the three months ended June 30, 2020 and 2019, respectively, and a gain of $129 million and a loss of $19 million for the six months ended June 30, 2020 and 2019, respectively.  The cumulative change was a gain of $301 million as of June 30, 2020.
