Rental incentives relate to the straight-lining effect of operating lease payments over the lease term. Non-current contingent consideration reduced in 2016 mainly due to the reclassification to current liabilities as payments are due in 2017. 'Other' mainly includes the long-term portion of deferred insurance income.
