These payments are contingent upon the occurrence of certain future events and, given the nature of these events, it is unclear when, if ever, the Company may be required to pay such amounts. Further, the timing of any future payment is not reasonably estimable. As of September 30, 2019, the maximum amount that may be payable in the future under the Company’s current collaborative agreements is $80.0 million. Manufacturing Commitments In 2018, the Company executed a commercial agreement with one of its manufacturers for future production of antibody through calendar 2025. In May 2019, the agreement was amended to reduce the number of committed antibody batches for an agreed-upon exit fee, which was recorded as research and development expense in the first quarter of 2019. After further negotiations, the Company’s noncancelable commitment for future production is approximately €5 million at September 30, 2019.
