Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

SeaChange International, Inc. (the “Company”) approved a plan to implement cost-saving actions, primarily through a reduction in force, that are anticipated to result in annualized cost savings of approximately $11 million after the actions are complete. The reduction in force has been implemented immediately within the U.S. and, to comply with non-U.S. legal requirements, will be implemented on an international basis over the next several fiscal quarters. The Company anticipates the actions will result in restructuring and severance charges of approximately $1.3 million in the fourth quarter and possible additional charges in future quarters as the non-U.S. actions are implemented. These reductions reflect the Company’s ability to streamline its activities now that its next generation software products have been brought to market and are being deployed around the globe.

A copy of a press release describing the above-referenced matters is attached hereto as Exhibit 99.1 and the information contained therein, including in the forward-looking statement disclaimer at the end of the press release, is incorporated by reference into this Item 2.05 of this Current Report on Form 8-K.

Any statements contained in this Current Report on Form 8-K that do not describe historical facts, including without limitation statements regarding the impact of cost savings actions including anticipated cost savings, the timing to implement the cost saving actions, and the amount and timing of restructuring and severance charges, are neither promises nor guarantees and may constitute forward-looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995. Any such forward-looking statements contained herein are based on current assumptions and expectations, but are subject to a number of risks and uncertainties that may cause actual results to differ materially from expectations. Information on factors that could cause actual results to differ from those anticipated is detailed in various publicly available documents made by the Company from time to time with the Securities and Exchange Commission, including but not limited to, those appearing under the caption “Risk Factors” in the Company’s Annual Report on Form 10-K filed on April 4, 2014. Any forward-looking statements should be considered in light of those factors. The Company cautions readers not to place undue reliance on any such forward-looking statements, which speak as of the date they are made. The Company disclaims any obligation to publicly update or revise any such statements to reflect any change in Company expectations or events, conditions or circumstances on which any such statements may be based, or that may affect the likelihood that actual results may differ from those set forth in the forward-looking statements.
