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 September 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 September 30, 2019 and 2018, was $7.1 million and $6.3 million, respectively. Operating lease expense for the nine months ended September 30, 2019 and 2018, was $22.9 million and $20.9 million, respectively. Charges related to our operating leases that are variable, including variable common area maintenance charges and other management-related costs, and not included in the measurement of the lease liabilities, were $2.2 million for the three months ended September 30, 2019 and $7.4 million for the nine months ended September 30, 2019.
