Deferred revenue is in respect of the upfront fee and development milestones payments received from collaboration agreements in advance of services performed by the Group (Note 2).

On implementation of IFRS16, previously recognized deferred rent balances were reclassified to right-of-use assets (see Note 13). As at December 31, 2019, the remaining deferred rent balances represent lease incentives granted on certain short-term leasehold property agreements which terminated during the year ended December 31, 2020.
