Certain banking facilities are leased under arrangements expiring at various dates through the year 2054. We account for these leases on a straight-line basis due to escalation clauses. All leases are accounted for as operating leases, except for one capital lease. Rental expense for premises amounted to $4.0 million, $4.1 million and $3.9 million in 2017, 2016 and 2015. Included in the rental expense for premises are leases entered into with two S&T directors, which totaled $0.2 million in 2017, and $0.3 million in 2016 and 2015. Minimum annual rental and renewal option payments for each of the following five years and thereafter are approximately:
