Employee Benefit Plans [Abstract] |
Employee Benefit Plans | 8. Employee Benefit Plans ﻿ The Company has certain defined contribution profit sharing and 401(k) plans covering substantially all of its employees in the United States and Europe. The Company provides matching contributions to the Company’s 401(k) plan. Company contributions are generally discretionary. For the years ended December 31, 2017, 2016 and 2015, expenses related to these plans amounted to $2,601, $1,601 and $1,487, respectively. ﻿ Long-Term Cash Incentive Plan ﻿ In 2009, the Company adopted the Stoneridge, Inc. Long-Term Cash Incentive Plan (the “LTCIP”) and granted awards to certain officers and key employees. Awards under the LTCIP provided recipients with the right to receive cash three years from the date of grant depending on the Company’s earnings per share performance for the defined performance period. If the participant voluntarily terminated employment or was discharged for cause, as defined in the LTCIP, the award would be forfeited. The Company granted Phantom Share awards under the LTCIP in 2013 that vested in February 2016 and were paid in March 2016 based on the Company’s earnings per share performance for each fiscal year of 2013, 2014 and 2015. As of December 31, 2017 and 2016, the Company recorded a liability of $0 for the performance based awards granted under the LTCIP. There were no performance based awards granted under the LTCIP during the years ended December 31, 2017, 2016 or 2015. ﻿
