The guidance in ASU 2016-02 (as subsequently amended by ASU 2018-01, ASU 2018-10, ASU 2018-11 and ASU 2018-20) requires that a lessee recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. We have adopted this standard using the modified retrospective approach. Refer to Note 11, Leases, for more information regarding our leases and the adoption of the new standard.
