9. Leases

We have various non-cancelable lease agreements for certain of our offices with original lease periods expiring between 2019 and 2029. Our lease terms may include options to extend or terminate the lease when it is reasonably certain we will exercise that option. Certain of the arrangements have free rent periods or escalating rent payment provisions. Leases with an initial term of twelve months or less are not recorded on the consolidated balance sheets. We recognize rent expense on a straight-line basis over the lease term. Additionally, we sublease certain operating leases to third parties primarily as a result of moving to a centralized corporate office in Santa Monica, California in 2018.

Lease Cost

The components of lease cost were as follows:

Lease Term and Discount Rate

The weighted-average remaining lease term (in years) and discount rate related to the operating leases were as follows:

As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the lease commencement date to determine the present value of lease payments.

Maturity of Lease Liabilities

The present value of our operating lease liabilities as of September 30, 2019 were as follows:

As of September 30, 2019, we have additional operating leases for facilities that have not yet commenced with lease obligations of $14.2 million. These operating leases will commence between 2019 and 2021 with lease terms of greater than one years to five years. This table does not include lease payments that were not fixed at commencement or modification.

In 2018, we exited various operating leases prior to the end of the contractual lease term, primarily as a result of moving to a centralized corporate office located in Santa Monica, California. The charges, recorded as general and administrative expenses, primarily included the present value of our remaining lease obligation on the cease use dates that occurred during the period, net of estimated sublease income. As of December 31, 2018, we exited all properties associated with this event. On January 1, 2019, under the transition provisions of ASU 2016-02 (Topic 842), we adjusted the initial measurement of the lease asset related to the lease exit properties by $32.1 million which represents the carrying amount of the associated lease exit liability as of December 31, 2018. Changes to our estimated sublease income, including actual contracted sublease income, may result in impairment of the right-of-use asset in the period determined.

Prior to January 1, 2019, we had several lease agreements where we were deemed the owner under build-to-suit lease accounting. The value of the leased property and corresponding financing obligations was included in property and equipment, net and other liabilities, respectively, on our consolidated balance sheets as of December 31, 2018. Net assets capitalized under build-to-suit leases were $48.4 million as of December 31, 2018. As part of the adoption of Topic 842, we derecognized those assets and liabilities and recorded the difference as an adjustment to accumulated deficit at January 1, 2019. These leases are included within the right-of-use asset and lease liability balances on our consolidated balance sheet as of September 30, 2019.

Other Information

Cash payments included in the measurement of our operating lease liabilities were $16.2 million and $49.4 million for the three and nine months ended September 30, 2019, respectively.

Lease liabilities arising from obtaining operating lease right-of-use assets was $13.3 million for the nine months ended September 30, 2019, respectively.
