Note 13 - Commitments
The Company leases equipment, office and laboratory space under several non-cancellable operating leases that expire between September 2017 and June 2028. 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 clinical laboratory operations and certain research operations. 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 $1,752, $1,704, and $1,623 (net of real estate tax abatement received of $61 for years 2016 and 2015) during fiscal years 2017, 2016 and 2015, respectively. Total rent expense incurred by the Company during fiscal 2017, 2016 and 2015 for all its facilities was approximately $4,658, $4,572 and $4,504, respectively.
