Fair Value Measurement
The Company complies with ASC 820 Fair Value Measurements, for its financial assets and liabilities that are re-measured and reported at fair value at each reporting period, and non-financial assets and liabilities that are re-measured and reported at fair value at least annually. In general, fair values are determined by:
Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities.
Level 2 inputs utilize data points that are observable such as quoted prices, interest rates and yield curves.
Level 3 inputs are unobservable data points for the asset or liability, and includes situations where there is little, if any, market activity for the asset or liability.
The following tables present information about the Company’s assets that are measured at fair value on a recurring basis as of December 31, 2020 and December 31, 2019 and indicates the fair value hierarchy of the valuation techniques the Company utilized to determine such fair value.

About Fair Value Disclosures

Fair value disclosures classify all assets and liabilities measured at fair value into a three-level hierarchy: Level 1 (quoted market prices), Level 2 (observable inputs like yield curves), and Level 3 (unobservable inputs requiring management estimates). The proportion of Level 3 assets directly reflects how much of the balance sheet depends on internal models rather than market evidence.

Key signals: a growing Level 3 balance relative to total fair-value assets increases valuation uncertainty and earnings volatility risk. Watch for transfers between levels — assets moving from Level 2 to Level 3 often signal deteriorating market liquidity. Unrealized gains and losses on Level 3 positions flow through earnings or other comprehensive income, so large swings deserve scrutiny. For financial institutions, examine the sensitivity disclosures that show how Level 3 valuations change under alternative assumptions. Compare the fair value of debt against its carrying amount to gauge hidden leverage.
