Commitments and Contingencies

5. Commitments and Contingencies

Preclinical Studies and Clinical Trials: The Company enters into contractual agreements with contract research organizations in connection with preclinical and toxicology studies and clinical trials. Amounts due under these agreements are invoiced to the Company on predetermined schedules during the course of the studies and clinical trials and are not refundable regardless of the outcome. The Company has a contractual obligation related to the expected future costs to be incurred to complete the ongoing preclinical studies and clinical trials. The remaining commitments, which have cancellation provisions, total $1.8 million at October 31, 2020.

Contingencies: From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of business activities. The Company accrues a liability for such matters when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. There were no contingent liabilities requiring accrual at October 31, 2020.

As a result of the terms of grant income received in prior years, upon successful regulatory approval and following the first commercial sale of certain DME products, the Company will be required to pay royalty fees of up to $1.0 million within 90 days of the first commercial sale of the product subject to certain fee caps and follow on payments depending upon commercial success and type of product. Given the stage of development of the current pipeline of products it is not possible to predict with certainty the amount or timing of any such liability.
