LEASES

In 2011, we entered into leases of certain tractors under operating leases which expired in 2015. Rental expense for these leases was included in rent and purchased transportation expense within the Consolidated Statements of Income. At December 31, 2015, we had no future lease payments under non-cancelable revenue equipment operating leases.

Rental expense under these non-cancelable revenue equipment operating leases for the years ended December 31, 2015, 2014, and 2013 was as follows (in thousands):



2015	$	584
2014	1,565
2013	1,593
