Verint Updates Expected Timing Regarding the Completion of its Audit and Becoming Current With SEC Filings

MELVILLE, N.Y.—(BUSINESS WIRE)—Nov. 5, 2007— Verint Systems Inc. (Pink Sheets: VRNT) today announced an update to its expected timing regarding completing its audit and becoming current with its SEC filings. Previously, Verint had indicated that it was working toward being current by January 31, 2008. While Verint continues to commit all available resources towards achieving that goal, the company believes that it is likely to be delayed from that timetable as a result of its examination of accounting treatment for revenue recognition under complex contractual arrangements under AICPA Statement of Position (SOP) 97-2, Software Revenue Recognition (“SOP 97-2”). Based on currently available information, Verint believes that any revenue adjustments resulting from this examination will relate solely to the timing of revenue recognition and are not expected to impact historically reported cash balances, cash flows, the existence of Verint’s aggregate revenues or the validity of the transactions underlying the company’s revenue.

While the company has made significant progress on its previously announced internal review of certain accounting matter, in connection with the audit of the company’s financial statements for fiscal year 2006 (ended January 31, 2007) by its independent registered public accountants, the company is conducting a review of its recognition of revenue based on the application of SOP 97-2. In connection with this examination, Verint has begun performing a comprehensive review of its license and sale agreements, as well as re-performing technical calculations associated with the establishment of vendor specific objective evidence (“VSOE”). VSOE calculations involve making determinations regarding the fair value of the company’s maintenance, professional and implementation services, as well as the application of the relative fair value method to allocate revenue to each element of the company’s bundled hardware and software arrangements. If the company for accounting purposes is unable to determine the fair value of an undelivered element within a multiple element arrangement, as defined by VSOE, revenue for the entire arrangement is deferred until all elements have been delivered.

Verint currently expects that there will likely be some impact on the financial information and guidance that the company has reported in its press releases, conference calls and Form 8-Ks since April 17, 2006. Although Verint has previously cautioned that all of the financial information contained in its press releases, conference calls and Form 8-Ks since April 17, 2006 has been “preliminary, not complete, and expected to change,” Verint has concluded that its financial disclosure and guidance disclosure contained in its press releases and filings on Form 8-Ks since April 17, 2006 should no longer be relied upon. Also, until the SOP 97-2 evaluation is complete, the Company may not be in a position to provide revenue and other income statement information to investors.

Verint is continuing to examine the SOP 97-2 matters described above, as well as other revenue recognition and any other issues that may arise during the completion of the audit of open and prior periods. There can be no assurance that Verint will not discover additional accounting errors or issues or that such errors or issues, if they exist, will not be material. Because of the uncertainty regarding how long this review and the company’s audit generally will take, as well as the impact, if any, on the company’s timetable resulting from the review process of Comverse Technology, Inc. (the company’s majority shareholder), the company can not provide an updated filing date at this time.
