Other Commitments, Indemnifications and Contingencies

From time to time, the Company receives inquiries from various state and municipal taxing agencies with respect to the remittance of sales, use, telecommunications, excise, and income taxes. Several jurisdictions currently are conducting tax audits of the Company's records. The Company collects from its customers or has accrued for taxes that it believes are required to be remitted. The amounts that have been remitted have historically been within the accruals established by the Company. The Company adjusts its accrual when facts relating to specific exposures warrant such adjustment.

During the first nine months of fiscal 2019, the Company determined that additional sales taxes were probable of being assessed and estimable in multiple states as a result of preliminary findings from current sales and use tax audits. As a result, the Company estimated an incremental sales tax liability of $6.5 million, which was recorded as general and administrative expense in the consolidated statements of operations during the first nine months of fiscal 2019.

Legal Proceedings

The Company from time to time may be involved in a variety of claims, lawsuits, investigations and other proceedings, including patent infringement claims, employment litigation, regulatory compliance matters and contractual disputes, that can arise in the normal course of the Company's operations.

On November 30, 2018, the Company was named as a defendant in Rainey Circuit LLC v. 8x8 Inc., by way of a Complaint filed by Plaintiff Rainey Circuit LLC in the District of Delaware (Civil Action No. Case 1:18-cv-01903-MN, the Complaint). The Complaint alleges that the Company infringes U.S. Patent No. 8,131,824 with regards to alleged activities concerning the Company's sales or or uses of a multimedia messaging system as allegedly implemented in connection with the Company’s Virtual Office application. Given the early stage of this lawsuit, it is not possible as of the date of this filing to provide an estimated amount of any loss or range of loss that may occur.

Litigation is inherently unpredictable and subject to significant uncertainties, and there can be no assurances that favorable final outcomes will be obtained. The above-referenced lawsuit and future litigation could be costly to defend, could impose significant burdens on employees and cause the diversion of management's attention, and could upon resolution have a material adverse effect on the Company's business, results of operations, financial condition and cash flows.
