Our operating leases that have commenced have terms that expire beginning 2027 through 2036 and consist of office space and research and development laboratories, including our corporate headquarters. Certain of these lease agreements contain clauses for renewal at our option. As we were not reasonably certain to exercise any of these renewal options at commencement of the associated leases, no such options were recognized as part of our right-of-use (ROU) assets or operating lease liabilities.
