Accounting Policies [Abstract]

Cash and Cash Equivalents and Concentration

Cash and Cash Equivalents and Concentration

The Company considers highly liquid investments with maturities of three months or less at the date of acquisition as cash equivalents in the accompanying condensed consolidated financial statements. The Company has not experienced any losses related to these balances; however, as of June 30, 2022, $11,322 of the cash and cash equivalents balance was in excess of Federal Deposit Insurance Corporation limits. The Company had restricted cash balances of $6,251 for each of the periods ended June 30, 2022, and December 31, 2021. The June 30, 2022, and December 31, 2021, balances both include $6,000 and $250, which represent collateral for two irrevocable standby letters of credit. See "Note 8 - Long-Term Debt, Net of Debt Discount and Financing Fees."

Share-Based Compensation

Stock-Based Compensation

The Company measures stock options granted to employees and directors at a premium price based on market conditions, such as the trading price of the Company’s common stock, using a Monte Carlo Simulation in estimating the fair value at grant date. The determination of the fair value is affected by the Company's stock price, as well as assumptions regarding several subjective variables. These variables include, but are not limited to, the Company’s expected stock price volatility over the term of the awards. The Company determines the expected life of each award giving consideration to the contractual terms, vesting schedules, and post-vesting forfeitures. The Company uses the risk-free interest rate on the implied yield currently available on U.S. Treasury issues with an equivalent remaining term approximately equal to the expected life of the award. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods in the Company’s consolidated statements of operations. The expense has been reduced for forfeitures as they occur.

The Company recognizes expense for all stock-based compensation awards, including stock options, restricted stock units ("RSUs"), and performance stock units ("PSUs") granted to employees eligible for retirement, as defined within the award notice and allowing for continued vesting post-retirement, over the retirement notice period and continuously updates its estimate of expense over the notice period each reporting period if a retirement notice has not been provided.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In November 2021, the Financial Accounting Standards ("FASB") amended ASC 832, Government Assistance (issued under Accounting Standards Update ("ASU") 2021-10, "Disclosures by Business Entities about Government Assistance"). This amendment requires annual disclosures about transaction with a government that are accounted for by applying a grant or contribution accounting model by analogy, including, (1) the types of transactions; (2) the financial statement line items affected by the transaction, and; (3) significant terms and conditions associated with the transactions. The Company adopted the guidance on January 1, 2022, the adoption of ASU 2021-10 is not expected to have a material impact on the the Company's condensed consolidated financial condition, results of operations or disclosures.

Fair Value Measurement

Fair value is defined as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy defines a three-level valuation hierarchy for classification and disclosure of fair value measurements as follows:

Level 1 – Quoted prices in active markets for identical assets or liabilities.

Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

There has been no movement between Level 1 and Level 2 or between Level 2 and Level 3 from December 31, 2021 to June 30, 2022. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.
