Commitments And Contingencies Disclosure [Abstract] |
Commitments and Contingencies | NOTE 7. COMMITMENTS AND CONTINGENCIES Litigation From time to time, the Company may be subject to various claims and legal proceedings in the ordinary course of business. If the potential loss from any claim, asserted or unasserted, or legal proceeding is considered probable and the amount is reasonably estimable, the Company will accrue a liability for the estimated loss. There were no contingent liabilities recorded as of March 31, 2022. Commitments On December 20, 2021, the Company completed a purchase of 13 acres of land in the Verona Technology Park in Verona, WI, which is planned to be the site of an approximately 140,000 square foot drug manufacturing facility and an approximately 115,000 square foot laboratory and office facility to support process development and analytical activities. Arrowhead intends to invest between $200 million and $250 million into the buildout of the facilities. As part of this acquisition, the Company also entered into a development agreement with the City of Verona to construct certain infrastructure improvements within the TIF district, and will be reimbursed by the City of Verona by future tax increment revenue generated from the developed property. The total amount of funding that City of Verona will pay as reimbursements under the TIF program for these improvements is not guaranteed and will depend on future tax revenues generated from the developed property. Technology License Commitments The Company has licensed from third parties the rights to use certain technologies for its research and development activities, as well as in any products the Company may develop using these licensed technologies. These agreements and other similar agreements often require milestone and royalty payments. Milestone payments, for example, may be required as the research and development process progresses through various stages of development, such as when clinical candidates enter or progress through clinical trials, upon a new drug application and upon certain sales level milestones. These milestone payments could amount to the mid to upper double-digit millions of dollars. During the three and six months ended March 31, 2022 and 2021, the Company did not reach any milestones. Under certain agreements, the Company may be required to make mid to high single-digit percentage royalty payments based on a percentage of sales of the relevant products.
