FAIR VALUE MEASUREMENTS.
16. FAIR VALUE MEASUREMENTS.

The fair value hierarchy prioritizes the inputs used in valuation techniques into three levels, as follows:


Level 1 – Observable inputs – unadjusted quoted prices in active markets for identical assets and liabilities;
     

Level 2 – Observable inputs other than quoted prices included in Level 1 that are observable for the asset or liability through corroboration with market data; and
     

Level 3 – Unobservable inputs – includes amounts derived from valuation models where one or more significant inputs are unobservable. For fair value measurements using significant unobservable inputs, a description of the inputs and the information used to develop the inputs is required along with a reconciliation of Level 3 values from the prior reporting period.

Pooled separate accounts – Pooled separate accounts invest primarily in domestic and international stocks, commercial paper or single mutual funds. The net asset value is used as a practical expedient to determine fair value for these accounts. Each pooled separate account provides for redemptions by the Retirement Plan at reported net asset values per share, with little to no advance notice requirement, therefore these funds are classified within Level 2 of the valuation hierarchy.


Long-Lived Assets Held-for-Sale – The Company recorded its long-lived assets associated with its property and equipment held-for-sale at fair value at December 31, 2020 and 2019 of $48,548,000 and $70,400,000, respectively. The fair values of these assets are based on observable values for the assets through corroboration with market data and are designated as Level 3 inputs.


Warrants issued to Senior Noteholders – The Company’s warrants issued December 22, 2019, were valued using the Black-Scholes Valuation Model and adjusted for quarterly. On August 5, 2020, these warrants were exercised in full and prior to exercise, the Company adjusted their fair value using the following assumptions (fair value dollars in thousands):

    Fair Value  
12/22/19   $ 1.00       178.0 %     0.08 %         0.10     $ 8,474  

The assumptions used and related fair value for these warrants as of December 31, 2019 were as follows (fair value dollars in thousands):

Warrants issued in Equity Offering – The Company issued pre-funded warrants and other warrants with exercise prices of $0.001 and $9.757, respectively. The Company valued these warrants upon issuance using the Binomial valuation methodology. On November 16, 2020, the pre-funded warrants were exercised, and as a result, were revalued immediately prior to their exercise. Further, the other warrants were amended on November 24, 2020, resulting in equity accounting, and accordingly were revalued immediately prior to their amendment. The assumptions used were as follows (fair value dollars in thousands):


Warrant Type   Valuation Date   Exercise
Price
    Volatility     Risk Free

    Fair Value

Pre-funded   11/16/2020   $ 0.01       97.0 %     0.40 %     4.95     $ 21,916  
Other   11/24/2020   $ 9.76       135.0 %     0.13 %     1.45     $ 31,231  

The fair values of the warrants are based on unobservable inputs and are designated as Level 3 inputs. The changes in the Company’s fair value of its Level 3 inputs with respect to its warrants were as follows (in thousands):
