[1] Based on the rights and privileges of Series B Preferred Stock, since the Company did not obtain shareholder approval at March 31, 2018, the then outstanding Series B Preferred Stock became redeemable at the option of OFI. Consequently, in each reporting period commencing March 31, 2018, the outstanding Series B Preferred Stock is recorded at its maximum redemption value until occurrence of redemption or conversion. These shares were cancelled as a result of the entry into the Remediation Agreement on September 24, 2018 as described below (see also Note 10).
