Summary of Significant Accounting Policies Summary of Significant Accounting Policies
The changes below were made to the Company's significant accounting policies previously disclosed in Note 3, Summary of Significant Accounting Policies, in its Annual Report on Form 10-K, filed on February 25, 2022, for the year ended December 31, 2021.
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 March 31, 2022, $14,059 of the cash and cash equivalents balance was in excess of Federal Deposit Insurance Corporation limits. As of March 31, 2022, and December 31, 2021, the Company had restricted cash balances of $6,251 and $6,251, respectively. The March 31, 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."
The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the condensed consolidated balance sheets that sum to the total of the same amounts shown in the condensed consolidated statements of cash flows:
(In thousands) March 31,
December 31,
Cash and cash equivalents $ 14,559  $ 32,756 
Restricted cash 6,251  6,251 
Total cash, cash equivalents, and restricted cash shown in the statement of cash flows $ 20,810  $ 39,007 
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
The Company’s management has reviewed and considered all recent accounting pronouncements and believe there are none that could potentially have a material impact on the Company’s condensed consolidated financial condition, results of operations, or disclosures.
