​ Deferred revenue Collaborative Arrangement The Company recorded deferred license fee revenue in connection with a Clinical Research and Co-Promotion Agreement with Health Tech Connex Inc. (“HTC”) (the “Co-Promotion Agreement”), as more fully described in the 2021 10-K. Deferred revenue as of both September 30, 2022 and December 31, 2021 included approximately $200 thousand of license fees not yet recognized under the Co-Promotion Agreement. License fee revenue recognized is included in other revenue in the unaudited condensed consolidated statements of operations and comprehensive loss. On January 31, 2022, the Company notified HTC of its material breaches under the Co-Promotion Agreement which HTC failed to cure under the terms of the Co-Promotion Agreement. As such it is the Company’s position that this exclusivity right is no longer in effect. The Company and HTC have been discussing opportunities to work together moving forward. Noncash Consideration in Acquisition Deferred revenue as of December 31, 2021 included approximately $100 thousand for the fair value of the remaining 16 PoNS devices to be transferred that had been included as noncash consideration in the Company’s acquisition of Heuro Canada, Inc. (“Heuro”). During the nine months ended September 30, 2022, the remaining 16 PoNS devices were transferred and the remaining $100 thousand of deferred revenue was recognized in Product Sales in the unaudited condensed consolidated statements of operations and comprehensive loss. During the nine months ended September 30, 2021, there were four PoNS devices transferred which resulted in the recognition of $30 thousand of deferred revenue in Product Sales in the unaudited condensed consolidated statements of operations and comprehensive loss.
