In respect of the group's commitment to significant property leases, there are no contingent rentals payable, or restrictions on dividends, debt or further leasing imposed by these lease arrangements. Wherever possible, the group ensures that it has the benefit of security of tenure where this is required by operational and accommodation strategies. Escalation of rents is via rent reviews at agreed intervals.

The company had no operating lease commitments at 31 March 2017 or 31 March 2016.
