Research & Development Tax Credit

The Company benefits from the U.K. Small and Medium-sized Enterprise R&D Tax Credit scheme, or the SME scheme, under which it can obtain a refundable credit of up to 33.4% of eligible research and development expenses incurred by the Company in the U.K.. Eligible expenses generally include employment costs for research staff, consumables, software and certain internal overhead costs incurred as part of research projects.

The Company submitted a claim seeking to obtain tax credits for qualifying R&D expenses incurred in the years ended December 31, 2015 and 2016. In September 2019, the Company received a partial payment of $10.5 million from Her Majesty’s Revenue and Customs, the U.K.’s government tax authority. Given the claim review has not been finalized, the credit received is recorded as a deferred liability within Accounts payable, accrued expenses, and other liabilities.
