Commitments and ContingenciesLease and Other Commitments The Company entered into various non-cancelable operating lease agreements for its facilities with remaining lease terms from less than one year to slightly over nine years. See Note 5 to these unaudited condensed consolidated financial statements for additional detail on the Company's operating and finance lease commitments. In the three and nine months ended September 30, 2020, the Company entered into several non-cancelable vendor agreements with terms up to three years for a total purchase commitment of $28.1 million and $51.0 million, respectively. Legal Matters On December 1, 2016, the Company filed a patent infringement lawsuit against Telesign Corporation (Telesign) in the United States District Court, Northern District of California, alleging infringement of United States Patent No. 8,306,021 (021), United States Patent No. 8,837,465 (465), United States Patent No. 8,755,376 (376), United States Patent No. 8,736,051 (051), United States Patent No. 8,737,962 (962), United States Patent No. 9,270,833 (833), and United States Patent No. 9,226,217 (217). Telesign filed a motion to dismiss the complaint on January 25, 2017. In two orders, issued on March 31, 2017 and April 17, 2017, the court granted Telesigns motion to dismiss with respect to the 962, 833, 051 and 217 patents, but denied Telesigns motion to dismiss as to the 021, 465 and 376 patents. On August 23, 2017, Telesign petitioned the U.S. Patent and Trademark Office (U.S. PTO) for inter partes review of the 021, 465, and 376 patents. On March 9, 2018, the U.S. PTO denied Telesigns petition for inter partes review of the 021 patent and granted Telesigns petitions for inter partes review of the 465 and 376 patents. On March 6, 2019, the U.S. PTO found all challenged claims of the 465 and 376 patents unpatentable. The Company appealed the decisions to the United States Court of Appeals for the Federal Circuit who, on June 10, 2020, affirmed the U.S. PTO's rulings. The district court litigation had been stayed pending resolution of the inter partes reviews (and appeals from them). The appeals are now concluded and the district court has reopened the case and set trial on the 021 Patent for July 2021. The Company is seeking a judgment of infringement, a judgment of willful infringement, monetary and injunctive relief, enhanced damages, and an award of costs and expenses against Telesign. In addition to the litigation discussed above, from time to time, the Company may be subject to legal actions and claims in the ordinary course of business. The Company has received, and may in the future continue to receive, claims from third parties asserting, among other things, infringement of their intellectual property rights. Future litigation may be necessary to defend the Company, its partners and its customers by determining the scope, enforceability and validity of third-party proprietary rights, or to establish our proprietary rights. The results of any current or future litigation cannot be predicted with certainty, and regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources, and other factors. Legal fees and other costs related to litigation and other legal proceedings are expensed as incurred and are included in general and administrative expenses in the accompanying condensed consolidated statements of operations. Indemnification Agreements The Company has signed indemnification agreements with all of its board members and executive officers. The agreements indemnify the board members and executive officers from claims and expenses on actions brought against the individuals separately or jointly with the Company for certain indemnifiable events. Indemnifiable events generally mean any event or occurrence related to the fact that the board member or the executive officer was or is acting in his or her capacity as a board member or an executive officer for the Company or was or is acting or representing the interests of the Company. In the ordinary course of business and in connection with our financing and business combinations transactions, the Company enters into contractual arrangements under which it agrees to provide indemnification of varying scope and terms to business partners, customers and other parties with respect to certain matters, including, but not limited to, losses arising out of the breach of such agreements, intellectual property infringement claims made by third parties and other liabilities relating to or arising from the Companys various products, or its acts or omissions. In these circumstances, payment may be conditional on the other party making a claim pursuant to the procedures specified in the particular contract. Further, the Companys obligations under these agreements may be limited in terms of time and/or amount, and in some instances, the Company may have recourse against third parties for certain payments. The terms of such obligations may vary. As of September 30, 2020 and December 31, 2019, no amounts were accrued related to any outstanding indemnification agreements.Other TaxesThe Company conducts operations in many tax jurisdictions within and outside the United States. In many of these jurisdictions, non-income-based taxes, such as sales, use, telecommunications and other local taxes are assessed on the Companys operations. Prior to March 2017, the Company had not billed nor collected these taxes from its customers and, in accordance with U.S. GAAP, recorded a provision for its tax exposure in these jurisdictions when it was both probable that a liability had been incurred and the amount of the exposure could be reasonably estimated. These estimates included several key assumptions including, but not limited to, the taxability of the Companys services, the jurisdictions in which its management believes it had nexus, and the sourcing of revenues to those jurisdictions. Starting in March 2017, the Company began collecting these taxes from customers in certain jurisdictions and since then has expanded to collect taxes in most jurisdictions where the Company operates. The Company is also in discussions with certain jurisdictions regarding its prior sales and other taxes, if any, that it may owe. In the event any of these jurisdictions disagrees with managements assumptions and analysis, the assessment of the Company's tax exposure could differ materially from management's current estimates. For example, one jurisdiction has assessed the Company for $38.8 million in taxes, including interest and penalties, which exceeded the $11.5 million the Company had accrued for the period covered by this assessment. The Company believes that this assessment is incorrect and has disputed it, paid the full amount as required by law, and is seeking a refund or settlement. The payment made in excess of the accrued amount is reflected as a deposit in the Company's accompanying condensed consolidated balance sheet. If a reasonable settlement cannot be reached in the near future, the Company will challenge the jurisdictions assessment in court. However, litigation is uncertain and a ruling against the Company may adversely affect its financial position and results of operation. As of September 30, 2020 and December 31, 2019, the liability recorded for these taxes was $25.3 million and $27.0 million, respectively.
