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):

Item 2.05. Costs Associated with Exit or Disposal Activities.

On June 16, 2016, Synaptics Incorporated (the “Company”) implemented a reduction in force program that will eliminate approximately 160 employee positions and reduce headcount globally by approximately 9%. The Company will also implement a space consolidation program affecting certain of its locations. These programs represent cost-cutting measures to align the Company’s cost structure consistent with its revenue levels.

The Company currently expects the reduction in force charges, consisting primarily of severance and other one-time benefits, to be in the range of $10.0 to $11.0 million; and the space consolidation, consisting primarily of lease cancellation charges and related costs, to be in the range of $3.0 to $4.0 million. The costs associated with the reduction in force and the space consolidation actions will be paid predominantly in cash. The Company anticipates that these charges will be recognized in the Company’s fourth fiscal quarter of 2016, as well as in fiscal 2017.

Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

(e) To align with the Company’s cost-cutting measures, including the reduction in force described in Item 2.05 above: Richard Bergman, the Company’s President, Chief Executive Officer and a member of its Board of Directors, requested a voluntary and temporary base salary reduction for the Company’s fiscal year ending June 24, 2017 of 20%; and each of Company’s other current “named executive officers” (Wajid Ali, Senior Vice President and Chief Financial Officer; Kevin Barber, Senior Vice President & General Manager, Smart Display Division; Scott Deutsch, Senior Vice President of Worldwide Sales; and Huibert Verhoeven, Senior Vice President & General Manager of the Human Interface Systems Division) requested a voluntary and temporary base salary reduction for the Company’s fiscal year ending June 24, 2017 of 10%. The temporary reduction will not affect the calculation of other benefits accruing to such officers to the extent such benefits are based on the officers’ base salary.

Item 8.01. Other Events.

To date, during its fourth quarter ending June 25, 2016, the Company has repurchased 1,045,841 shares at an average price of $64.14 per share, bringing its total share repurchase for fiscal 2016 to 2,714,554 shares, or approximately 7.2% of the shares outstanding at the beginning of fiscal 2016.
