NOTE 9. | FAIR VALUE
The fair value hierarchy prioritizes inputs to valuation techniques used to measure fair value into three broad levels: Level 1 — Observable inputs such as unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 — Inputs other than quoted prices in active markets that are observable either directly or indirectly, including: quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active or other inputs that are observable or can be corroborated by observable market data. Level 3 — Unobservable inputs that are supported by little or no market data and require the reporting entity to develop its own assumptions. At December 31, 2020 and 2019, our financial instruments included cash, cash equivalents, restricted cash, receivables, marketable securities, investments, accounts payable, and long-term debt. The carrying value of cash, cash equivalents, restricted cash, receivables, and accounts payable approximates fair value due to the short-term nature of the instruments. The fair value of long-term debt is estimated using quoted prices for similar debt (level 2 in the fair value hierarchy). At December 31, 2020 , the estimated fair value of our long-term debt was $23,839,007 which exceeds the carrying amount of $23,057,650. As discussed within Note 8, in connection with Yellowstone's initial public offering, BOC Yellowstone purchased an aggregate 7,719,779 Private Placement Warrants at a price of $1.00 per whole warrant. Each Private Placement Warrant is exercisable for one share of Yellowstone's Class A common stock at a price of $11.50 per share, and as such meet the definition of a derivative as outlined within ASC 815, Derivatives and Hedging. The Private Placement Warrants are recorded at fair value and are classified in long-term "Investments" on the consolidated balance sheet. The fair value of the Private Placement Warrants is classified as level 3 in the fair value hierarchy as the calculation is dependent upon company specific adjustments to the observable trading price of Yellowstone's public warrants for lack of marketability and related risk of forfeiture should no business combination occur. Subsequent changes in fair value will be recorded in the income statement during the period of the change. As of December 31, 2020, our re-measurement resulted in an unrealized loss of $2,933,516 and is included within "Unrealized gain (loss) on securities" within our consolidated statement of operations. Marketable equity securities and U.S. Treasury trading securities are reported at fair values. Substantially all of the fair value is determined using observed prices of publicly traded securities, level 1 in the fair value hierarchy.
