Operating leases include a variety of properties around the world. These properties are used as manufacturing facilities, distribution centers and sales offices. Lease expirations range from 2017 to 2026 with breaking periods specified in the lease agreements. Sublease income was $457 in 2016. Future sublease income is $500 in 2017, $487 in 2018, and $1,872 thereafter. Some of our operating leases include renewal options and escalation clauses.

In the fourth quarter of 2012, one of our foreign locations entered into a sale-leaseback transaction. As a result of this transaction, a deferred gain of approximately $4,500 was being amortized over the 6 year expected lease term. During 2015, we terminated the lease and recognized the remaining unamortized deferred gain into income. A gain of $2,108 was included in the Consolidated Statements of Earnings for the year ended December 31, 2015.
