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 2022 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 have 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. Our current subleases have total lease terms ranging from 11 to 96 months that will expire at various dates by fiscal year 2025.

As of October 31, 2020, we had two finance leases that had not commenced. These finance leases have immaterial aggregated undiscounted future payments and lease terms ranging from 1 to 3 years. These finance leases are expected to commence during the fourth quarter of fiscal year 2021 and as such, we did not reflect these leases on the condensed consolidated balance sheet as of October 31, 2020 and in the tables above. We did not have any operating leases that have not yet commenced as of October 31, 2020.

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. As of October 31, 2020 and 2019, we recorded $3.1 million and $2.8 million, respectively, in other long-term liabilities related to the present value of our estimated asset retirement obligation for our headquarters facility. The accretion expense, which was included in operating expenses in our condensed consolidated statements of operations, was not material for all periods presented.
