Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies | Commitments and Contingencies Legal Matters In the ordinary course of business, the Company may be subject to various legal proceedings and claims including alleged infringement of third-party patents and other intellectual property rights. The Company reviews the status of each matter and records a provision for a liability when it is considered both probable that a liability has been incurred and that the amount of the loss can be reasonably estimated. Legal fees incurred in connection with loss contingencies are recognized as incurred when the legal services are provided, and therefore are not recognized as a part of a loss contingency accrual. These provisions are reviewed quarterly and adjusted as additional information becomes available. We are not presently a party to any legal proceedings that in the opinion of our management would have a material adverse effect on our business, financial condition, operating results or cash flows. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors. Other Contingencies The Company is subject to audit in various jurisdictions, and such jurisdictions may assess additional income and sales tax liabilities against us. Although we believe our tax estimates are reasonable, the final outcome of tax audits and any related litigation could be materially different from our historical income and sales tax provisions and accruals. Developments in an audit or litigation could have a material effect on our operating results or cash flows in the period or periods for which that development occurs, as well as for prior and subsequent periods. Other Commitments The Company has contractual obligations for third-party technology used in the Company's solutions and for other services the Company purchases as part of normal operations. In certain cases, these arrangements require a minimum annual purchase commitment. As of October 31, 2017, the remaining aggregate minimum purchase commitment under these arrangements was approximately $17.5 million through fiscal year 2020.
