The Company has determined that it is unlikely that CEN Ukraine will have the ability to recover from the effects of the war in the foreseeable future. Subsequent to December 31, 2021, the Company authorized the issuance of 416,667 shares of its common stock upon conversion of the principal amount due under a note to a person.
