For some of our offices and data centers, we have entered into non-cancelable operating lease agreements with various expiration dates through 2035. Certain lease agreements include options to renew or terminate the lease, which are not reasonably certain to be exercised and therefore are not factored into our determination of lease payments.

Total operating lease costs were $21 million and $40 million, excluding short-term lease costs, variable lease costs and sublease income, each of which were immaterial, for the three and six months ended June 30, 2020, respectively.

In addition to the amounts above, as of June 30, 2020, we have operating leases, primarily for offices, that have not yet commenced with undiscounted cash flows of $359 million. These operating leases will commence between 2020 and 2022 with lease terms of 4 to 15 years.

Other contractual commitments consist of data center and IT operations and sales and marketing activities. There were no material contractual obligations that were entered into during the six months ended June 30, 2020 that were outside the ordinary course of business.

In addition to the amounts above, the repayment of our 2022 Notes with an aggregate principal amount of $765 million is due on June 1, 2022. Refer to Note 10 for further information regarding our Notes.

As of June 30, 2020, we had letters of credit in the aggregate amount of $20 million, primarily in connection with our customer contracts and operating leases.

From time to time, we are party to litigation and other legal proceedings in the ordinary course of business. While the results of any litigation or other legal proceedings are uncertain, management does not believe the ultimate resolution of any pending legal matters is likely to have a material adverse effect on our financial position, results of operations or cash flows, except for those matters for which we have recorded a loss contingency. We accrue for loss contingencies when it is both probable that we will incur the loss and when we can reasonably estimate the amount of the loss or range of loss.

Generally, our subscription agreements require us to defend our customers for third-party intellectual property infringement and other claims. Any adverse determination related to intellectual property claims or other litigation could prevent us from offering our services and adversely affect our financial condition and results of operations.
