Individual IPR&D projects and goodwill are tested for impairment on an annual basis in the fourth quarter, and in between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of each technology or our reporting unit below its carrying value. The impairment assessments resulted in the following activity during the years ended March 31, 2025 and 2024:

The Company's IPR&D projects, consistent with others in our industry, have risks and uncertainties associated with the timely and successful completion of the development and commercialization of product candidates, including our ability to confirm safety and efficacy based on data from clinical trials, our ability to obtain necessary regulatory approvals and our ability to successfully complete these tasks within budgeted costs. It is not permitted to market a human therapeutic without obtaining regulatory approvals, and such approvals require the completion of clinical trials that demonstrate that a product candidate is safe and effective. In addition, the availability and extent of coverage and reimbursement from third-party payers, including government healthcare programs and private insurance plans as well as competitive product launches, affect the revenues a product can generate. Consequently, the eventual realized values, if any, of acquired IPR&D projects may vary from their estimated fair values.
