Receivables of $126,000 are included in other current assets as at March 31, 2021. This relates to royalty payments receivable under a December 2005 Asset Purchase Agreement, or APA, whereby Xcyte Therapies, Inc., or Xcyte (a business acquired by the Company in March 2006), sold certain assets and intellectual property to ThermoFisher Scientific Company, or TSC (formerly Invitrogen Corporation), through the APA and other related agreements. The assets and technology were not part of the Company’s product development plan following the transaction between Xcyte and Cyclacel in March 2006. Accordingly, the company presented the $126,000 as other income during the three months ended March 31, 2021.
