|Leases Operating [Abstract]|
Note 3. Leases
We lease certain assets under operating leases, which primarily consist of real estate leases for 32 of our 235 service center locations and automotive leases for our company cars at December 31, 2018. Certain operating leases provide for renewal options, which can vary by lease and are typically offered at their fair rental value. We have not made any residual value guarantees related to our operating leases; therefore, we have no corresponding liability recorded on our Balance Sheets.
Future minimum annual lease payments for assets under operating leases as of December 31, 2018 are as follows:
Aggregate expense under operating leases was $12.6 million, $14.1 million and $13.8 million for 2018, 2017 and 2016, respectively. Certain operating leases include rent escalation provisions, which we recognize as expense on a straight-line basis. We did not have any assets under capital leases at each of December 31, 2018 and 2017.
