(6)  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, other than quoted market prices included within Level 1, 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:

The majority of the Company's Level 2 financial assets and liabilities are debt instruments with quoted market prices that are not considered to be traded on "active markets," as defined in GAAP. Accordingly, the debt instruments are reported in the foregoing table as Level 2 fair value.

Pursuant to an indemnification agreement, GCI Liberty has agreed to indemnify LI LLC for certain payments made to a holder of LI LLC’s 1.75% Exchangeable Debentures due 2046 (the “1.75% Exchangeable Debentures”). An indemnity asset in the amount of $281 million was recorded upon completion of the GCI Liberty Split-Off. In June 2018, Qurate Retail repurchased 417,759 of the 1.75% Exchangeable Debentures for approximately $457 million, including accrued interest, and GCI Liberty made a payment under the indemnification agreement to Qurate Retail in the amount of $133 million.

The remaining indemnification asset due to LI LLC pertains to the holder’s ability to exercise its exchange right according to the terms of the 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 1.75% Exchangeable Debentures at the time the exchange occurs.  The indemnification asset recorded in the consolidated balance sheets as of December 31, 2018 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 December 31, 2018, a holder of the 1.75% Exchangeable Debentures does not have the ability to exchange and, accordingly, such indemnification asset is included as a long-term asset in our consolidated balance sheets. Additionally, as of December 31, 2018, 332,241 of the 1.75% Exchangeable Debentures remain outstanding.
