Commitments and Contingencies

Facility and Computing Infrastructure-related Commitments

We have entered into non-cancelable agreements for certain of our offices and data centers with various expiration dates. Certain of our office leases are with an affiliate of our Chairman, David Duffield, who is also a significant stockholder (see Note 18). Our operating lease agreements generally provide for rental payments on a graduated basis and for options to renew, which could increase future minimum lease payments if exercised. This includes payments for office and data center square footage as well as data center power capacity for certain data centers. We generally recognize these expenses on a straight-line basis over the period in which we benefit from the lease. Total rent expense was $99 million, $82 million, and $72 million for fiscal 2019, 2018, and 2017, respectively.

In January 2014, we entered into a 95-year lease for a 6.9-acre parcel of vacant land in Pleasanton, California, under which we paid $2 million for base rent from commencement through December 31, 2020. Annual rent payments of $0.2 million plus increases based on increases in the Consumer Price Index begin on January 1, 2021 and continue through the end of the lease.

Additionally, we have entered into non-cancelable agreements with computing infrastructure vendors with various expiration dates.

As of January 31, 2019, the future minimum payments by year for our non-cancelable leases and computing infrastructure platforms are as follows (in thousands):

Legal Matters

We are a party to various legal proceedings and claims that arise in the ordinary course of business. We make a provision for a liability relating to legal matters when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular matter. In our opinion, as of January 31, 2019, there was not at least a reasonable possibility that we had incurred a material loss, or a material loss in excess of a recorded accrual, with respect to such loss contingencies.
