At 31 December 2006, UBS was obligated under a number of non-cancellable operating leases for premises and equipment used primarily for banking purposes. The significant premises leases usually include renewal options and escalation clauses in line with general office rental market conditions as well as rent adjustments based on price indices. However, the lease agreements do not contain contingent rent payment clauses and purchase options.

Operating lease contracts include non-cancellable long-term leases of office buildings in most UBS locations. At 31 December 2006, the minimum lease commitments for sixteen office locations each exceeded CHF 100 million. Non-cancellable minimum lease commitments for four office locations in New Jersey, London, Zurich and New York each exceeded CHF 500 million.
