Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	10. Commitments and Contingencies Litigation The Company is involved in various legal matters that arise in the ordinary course of its business. Some of these legal matters purport or may be determined to be class and/or representative actions, or seek substantial damages, or penalties. The Company has accrued amounts in connection with certain legal matters, including with respect to certain of the matters described below. There can be no assurance, however, that these accruals will be sufficient to cover such matters or other legal matters or that such matters or other legal matters will not materially or adversely affect the Company’s business, financial position, or results of operations. Employment Matters The Company has also been involved in various litigation, including purported class or representative actions with respect to matters arising under the California Labor Code and Private Attorneys General Act. The Company has retained outside counsel to represent it in these matters and is vigorously defending its interests. Legal Matters Related to Take 5 On April 1, 2018, the Company acquired certain assets and assumed liabilities of Take 5 Media Group (“Take 5”). In June 2019, as a result of a review of internal allegations related to inconsistency of data provided by Take 5 to its clients, the Company commenced an investigation into Take 5’s operations. In July 2019, as a result of the Company’s investigation, the Company determined that revenue during the fiscal year ended December 31, 2018 attributable to the Take 5 business had been recognized for services that were not performed on behalf of clients of Take 5 and that inaccurate reports were made to Take 5 clients about those services (referred to as the “Take 5 Matter”). As a result of these findings, in July 2019, the Company terminated all operations of Take 5, including the use of its associated trade names and the offering of its services to its clients and offered refunds to Take 5 clients of collected revenues attributable to Take 5 since the Company’s acquisition of Take 5. USAO and FBI Voluntary Disclosure and Investigation Related to Take 5 The Company voluntarily disclosed to the United States Attorney’s Office and the Federal Bureau of Investigation certain misconduct occurring at Take 5, a line of business that the Company closed in July 2019. The Company intends to cooperate in this and any other governmental investigations that may arise in connection with the Take 5 Matter. At this time, the Company cannot predict the ultimate outcome of any investigation related to the Take 5 Matter and is unable to estimate the potential impact such an investigation may have on the Company. Arbitration Proceedings Related to Take 5 In August 2019, as a result of the Take 5 Matter, the Company provided a written indemnification claim notice to the sellers of Take 5 (the “Take 5 Sellers”) seeking monetary damages (including interest, fees and costs) based on allegations of breach of the asset purchase agreement (the “Take 5 APA”), as well as fraud. In September 2019, the Take 5 Sellers initiated arbitration proceedings against the Company, alleging breach of the Take 5 APA as a result of the Company’s decision to terminate the operations of the Take 5 business, and seeking monetary damages equal to all unpaid earn-out payments under the Take 5 APA (plus interest, fees and costs). ). In 2020, the Take 5 sellers amended their statement of claim to allege defamation, relating to statements the Company made to customers in connection with terminating the operations of the Take 5 business, and seeking monetary damages for the alleged injury to their reputation. The Company filed its response to the Take 5 Sellers’ claims, and asserted indemnification, fraud and other claims against the Take 5 Sellers as counterclaims and cross-claims in the arbitration proceedings. The Company is currently unable to estimate the potential impact related to these arbitration proceedings, but the Company has retained outside counsel to represent the Company in these matters and intends to vigorously pursue the Company’s interests. Other Legal Matters Related to Take 5 The Take 5 Matter may result in additional litigation against the Company, including lawsuits from clients, or governmental investigations, which may expose the Company to potential liability in excess of the amounts being offered by the Company as refunds to Take 5 clients. The Company is currently unable to determine the amount of any potential liability, costs or expenses (above the amounts already being offered as refunds) that may result from any lawsuits or investigations associated with the Take 5 Matter or determine whether any such issues will have any future material adverse effect on the Company’s financial position, liquidity, or results of operations. Although the Company has insurance covering certain liabilities, the Company cannot assure that the insurance will be sufficient to cover any potential liability or expenses associated with the Take 5 Matter. Surety Bonds In the ordinary course of business, the Company is required to provide financial commitments in the form of surety bonds to third parties as a guarantee of its performance on and its compliance with certain obligations, including workers’ compensation insurance. If the Company were to fail to perform or comply with these obligations, any draws upon surety bonds issued on its behalf would then trigger the Company’s payment obligation to the surety bond issuer. The Company has outstanding surety bonds issued for its benefit of $7.5 million and $0.5 million as of March 31, 2021 and December 31, 2020, respectively.	17.
