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:

On July 13, 2016, the Board of Directors of pSivida Corp. (the “Company”) approved a site consolidation plan (the “Plan”) in support of the Company’s product development program under which the Company would conduct all future research and product development in a single location. Subject to an employee consultation process required by local law, the Company proposes to close its research facility in Malvern, United Kingdom and to locate all of its research and product development activities in the Company’s facility in Watertown, Massachusetts.

The Company expects the Plan will reduce pre-tax operating expenses by approximately $900,000 annually, beginning in the second quarter of its 2017 fiscal year, which ends December 31, 2016. The Plan is expected to be substantially completed in the first quarter of the Company’s 2017 fiscal year, which ends September 30, 2016, subject to local labor requirements.

The Company estimates that the implementation of the Plan will result in approximately $680,000 in total pre-tax charges, of which approximately $550,000 is expected to result in future cash outlays. Charges related to the Plan are expected to primarily consist of (i) employee severance and other termination benefits of approximately $490,000, (ii) equipment impairment charges of approximately $40,000, and (iii) accounting, legal and other costs directly related to the Plan of approximately $150,000. The Company expects the charges will be recorded primarily in the first quarter of its 2017 fiscal year, which ends September 30, 2016.

The actual charges as well as the actual reduction in annual operating expenses in connection with the Plan may vary depending upon various factors, including currency exchange rates and the outcome of the employee consultation process.

On July 15, 2016, the Company issued a press release announcing the Plan (the “Press Release”). The full text of the Press Release is attached hereto as Exhibit 99.1 and incorporated by reference herein.

The information contained in this Item 7.01, including Exhibit 99.1, is to be considered “furnished” pursuant to Item 7.01 of Form 8-K and shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that Section or Section 11 or 12(a)(2) of the Securities Act of 1933, as amended, nor shall it be deemed incorporated by reference in any filing or report with the Securities and Exchange Commission (“SEC”), whether made before or after the date hereof, regardless of any general incorporation language in such filing or report, except as shall be expressly set forth by specific reference in such filing or report.
