We have entered into various non-cancellable operating lease agreements for certain of our offices and data centers with lease periods expiring primarily between fiscal years 2020 and 2029. Certain of these arrangements have free or escalating rent payment provisions and optional renewal or termination clauses. Our operating leases typically include variable lease payments, which are primarily comprised of common area maintenance and utility charges for our offices and power and network connections for our data centers, that are determined based on actual consumption. Our operating lease agreements do not contain any residual value guarantees, covenants, or other restrictions.

We also entered into various finance lease arrangements to obtain servers and related equipment for our data center operations. These agreements are primarily for four years and certain of these arrangements have optional renewal or termination clauses. The leases are secured by the underlying leased servers and related equipment.

We sublease certain floors of our Redwood City, San Francisco, and London offices. These subleases have terms ranging from 31 to 55 months that will expire at various dates by fiscal year 2023.

As of October 31, 2019, we had operating leases for two of our data centers that have not yet commenced with aggregated undiscounted future payments of $17.2 million. These operating leases will commence in the later part of fiscal year 2020 and have lease terms ranging from 4 to 5 years and therefore, we did not reflect these on the condensed consolidated balance sheet as of October 31, 2019 and the tables above. We did not have any finance leases that have not yet commenced as of October 31, 2019.

We establish assets and liabilities for the present value of estimated future costs to return certain of our leased facilities to their original condition. Such assets are depreciated over the lease period into operating expense, and the recorded liabilities are accreted to the future value of the estimated restoration costs. For the nine months ended October 31, 2019, we recorded $2.8 million in other long-term liabilities related to the present value of our estimated asset retirement obligation for our headquarters facility. We did not have material asset retirement obligations as of January 31, 2019. The accretion expense, which was included in operating expenses in our condensed consolidated statements of operations, was not material for all periods presented.
