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 March 31, 2019, the weighted-average remaining lease term on these leases is approximately seven years and the weighted-average discount rate used to measure the lease liabilities is approximately 3.5%.

Our operating lease expense for the three months ended March 31, 2019 and 2018, was $7.3 million and $8.1 million, respectively. Charges related to our operating leases that are variable and therefore not included in the measurement of the lease liabilities were $2.2 million for the three months ended March 31, 2019.

We made lease payments of $9.9 million during the three months ended March 31, 2019. Our future undiscounted cash flows related to our operating leases and the reconciliation to the operating lease liability as of March 31, 2019, are as follows:
