LEASES.

All of our leases are operating leases and primarily consist of real estate leases for corporate offices, data centers, and other facilities. As of June 30, 2019, the weighted-average remaining lease term on our leases is approximately 7.0 years and the weighted-average discount rate used to measure the lease liabilities is 3.5%.

Operating lease expense for the three months ended June 30, 2019 and 2018, was $8.5 million and $6.5 million, respectively. Operating lease expense for the six months ended June 30, 2019 and 2018, was $15.8 million and $14.7 million, respectively.
