In connection with Olenik v. Lodzinski et al. (described below), Earthstone’s majority shareholder was also named in the lawsuit. The Company is currently in negotiations with its insurance carrier around an allocation of litigation costs above its deductible for all the parties named in the lawsuit. Once the allocation is agreed upon, cost will be assigned to each party affected. As of December 31, 2019, the Company has not recorded a receivable for prospective insurance settlement proceeds. Charges associated with this legal action are included in Transaction costs in the Consolidated Statements of Operations. Any proceeds received from the Company’s insurance carrier will be recorded as a reduction of Transactions costs in the period received.
