We lease buildings, motor vehicles and office equipment under operating leases. We expense rental charges for operating leases on a straight-line basis over the lease term taking into account rent concessions or holidays. Rent expenses under operating leases for the years ended June 30, 2016, 2015 and 2014 were approximately $17.4 million, $17.0 million and $16.5 million, respectively. At June 30, 2016 we had the following future minimum lease payments under non-cancelable operating leases (in thousands):
