Legal Proceedings and Claims	Legal Proceedings and Claims In the ordinary course of business, the Company is or may be involved in various legal or regulatory proceedings, claims or purported class actions related to alleged infringement of third-party patents and other intellectual property rights, commercial, corporate and securities, labor and employment, wage and hour and other claims. The Company has been, and may in the future be put on notice or sued by third-parties for alleged infringement of their proprietary rights, including patent infringement. In December 2018, the Company was named as a nominal defendant and certain of its current and former directors were named as defendants in a purported shareholder derivative action in the Delaware Court of Chancery. The complaint alleged that excessive compensation was paid to such directors for their service, included claims of breach of fiduciary duty and unjust enrichment, and sought restitution and disgorgement of a portion of the directors' compensation. Subsequently, three similar shareholder derivative actions were filed in the Delaware Court of Chancery. The cases were consolidated under the caption In re Salesforce.com, Inc. Derivative Litigation. The parties agreed to settle the consolidated action, and the Delaware Court of Chancery approved the settlement in December 2019. No appeals were filed and the deadline to file an appeal has passed. Tableau Litigation In July and August 2017, two substantially similar securities class action complaints were filed against Tableau and two of its now former executive officers. The first complaint was filed in the U.S. District for the Southern District of New York (the “Scheufele Action”). The second complaint was filed in the U.S. District Court for the Western District of Washington and was voluntarily dismissed on October 17, 2017. In December 2017, the lead plaintiff in the Scheufele Action filed an amended complaint, which alleged that between February 5, 2015 and February 4, 2016, Tableau and certain of its executive officers violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 (the "Exchange Act") and Rule 10b-5 promulgated thereunder, in connection with statements regarding Tableau’s business and operations by allegedly failing to disclose that product launches and software upgrades by competitors were negatively impacting Tableau’s competitive position and profitability. The amended complaint sought unspecified damages, interest, attorneys’ fees and other costs. In February 2018, the lead plaintiff filed a second amended complaint (the "SAC"), which contains substantially similar allegations as the amended complaint, and added as defendants two of Tableau’s now former executive officers and directors. Defendants filed a motion to dismiss the SAC in March 2018, which was denied in February 2019. Defendants filed an answer to the SAC in March 2019, and subsequently amended their answer in April 2019. On January 15, 2020, the court granted lead plaintiff’s motion for certification. The parties have completed fact discovery and engaged in expert discovery. The court has not yet set a trial date. In August 2018, Tableau was named as a nominal defendant in a purported shareholder derivative action in the United States District Court for the District of Delaware, allegedly on behalf of and for the benefit of Tableau, against certain of its now former directors and officers. The derivative action arises out of many of the factual allegations at issue in the Scheufele Action, and generally alleges that the individual defendants breached fiduciary duties owed to Tableau. The complaint seeks unspecified damages and equitable relief, attorneys' fees, costs and expenses. The case is currently stayed. In general, the resolution of a legal matter could prevent the Company from offering its service to others, could be material to the Company’s financial condition or cash flows, or both, or could otherwise adversely affect the Company’s operating results. The Company makes 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, estimated settlements, legal rulings, advice of legal counsel and other information and events pertaining to a particular matter. The outcomes of legal proceedings and other contingencies are, however, inherently unpredictable and subject to significant uncertainties. As a result, the Company is not able to reasonably estimate the amount or range of possible losses in excess of any amounts accrued, including losses that could arise as a result of application of non-monetary remedies, with respect to the contingencies it faces, and the Company’s estimates may not prove to be accurate. In management’s opinion, resolution of all current matters is not expected to have a material adverse impact on the Company’s consolidated results of operations, cash flows or financial position. However, depending on the nature and timing of any such dispute or other contingency, an unfavorable resolution of a matter could materially affect the Company’s current or future results of operations or cash flows, or both, in a particular quarter.
