Subsequent Events	15. Subsequent Events Interest Rate Swap On February 18, 2020, the Company entered into a float-to-fixed interest rate swap, with a notional amount of $50,000 to reduce the variability of London Inter-bank Offered Rate (“LIBOR”) based interest payments on a portion of variable rate debt outstanding on the Company’s 2019 Credit Facility, as disclosed in Note 5 to the consolidated financial statements, by swapping variable rate payments into fixed rate payments. Currently, borrowings under the 2019 Credit Facility bear interest based on a variable interest rate at either the Base Rate or LIBOR Rate (as defined in the Fourth Amended and Restated Credit Agreement). The interest rate swap will be settled monthly and will expire in March 2023. Authorization For Common Share Repurchase On February 24, 2020, the Board of Directors of Stoneridge, Inc. authorized the repurchase of $50.0 million of the Company’s outstanding Common Shares over the next 18 months. The repurchases may be made from time to time in either open market transactions or in privately negotiated transactions. Repurchases may also be made under Rule 10b5-1 plans, which permit Common Shares to be repurchased through pre-determined criteria. The timing, volume and nature of common share repurchases will be at the discretion of management, dependent on market conditions, other priorities of cash investment, applicable securities laws and other factors. This Common Share repurchase program authorization does not obligate the Company to acquire any particular amount of its Common Shares, and it may be suspended or discontinued at any time. Accelerated Share Repurchase Program Early Termination On February 25, 2020, Citibank N.A. notified the Company that it terminated early its commitment pursuant the accelerated share repurchase agreement and would deliver to the Company 364,604 Common Shares on February 27, 2020 based on the volume weighted-average price of our Common Shares during the term set forth in the accelerated share repurchase agreement. Citibank N.A.’s notice of early termination and the subsequent delivery Common Shares represents the final settlement of the Company’s share repurchase program pursuant to accelerated share repurchase agreement.
