Leases

The Company leases equipment, office and laboratory space under several non-cancellable operating leases that expire between September 2014 and May 2023. Certain leases include renewal options and rent escalation clauses. An entity owned by certain executive officers/directors of the Company owns the building that the Company leases as its main facility for laboratory operations and certain research operations. In March 2005, the Company amended and extended the lease for 12 years. In addition to the minimum annual rentals of space, the lease is subject to annual increases, based on the consumer price index. Annual increases are limited to 3% per year. Rent expense for this lease, inclusive of real estate taxes, approximated $1,623, $1,649 and $1,605 during fiscal years 2015, 2014 and 2013, respectively. Total rent expense incurred by the Company during fiscal 2015, 2014 and 2013 for all its facilities was approximately $4,504, $4,488 and $4,354, respectively.
