On an ongoing basis, the Company evaluates its estimates and judgments including those related to contingent value rights, the allowance for doubtful accounts, valuation of goodwill and intangible assets, recoverability and useful lives of tangible and intangible long-lived assets, accruals for players club card incentives and for potential liabilities related to any lawsuits or claims brought against the Company, fair value of financial instruments, stock compensation and valuation allowances for deferred tax assets. The Company bases its estimates and judgments on historical experience and other relevant factors impacting the carrying value of assets and liabilities. Actual results may differ from these estimates.</span></div>

CY2020	us-gaap	Concentration Risk Credit Risk ConcentrationRiskCreditRisk	Concentrations of Credit RiskThe Company’s financial instruments which potentially expose the Company to concentrations of credit risk consisted of cash and cash equivalents and trade receivables. The Company maintains cash with financial institutions in excess of federally insured limits, however, management believes the credit risk is mitigated by the quality of the institutions holding such deposits. For the years ended December 31, 2020, 2019 and 2018, gaming revenue from the State of Rhode Island accounted for 30%, 46% and 56% of total revenues, respectively. Based on the Master Video Lottery Terminal Contract (the “Contract”) with the State of Rhode Island and historical experience, the Company’s management believes any credit risk related to amounts owed to the Company by the State of Rhode Island to be minimal.
