Retirement Benefits [Abstract] |
Employee Benefits | Employee Benefits Defined Contribution Plan - 401(k) - We sponsor a defined contribution plan (the "Plan”). Eligible employees may make contributions in accordance with the Plan and IRS guidelines. In addition to the traditional 401(k), eligible employees are given the option of making an after-tax contribution to a Roth 401(k) or a combination of both. The Plan provides for automatic enrollment and for an automatic increase to the deferral percentage at January 1st of each year and each year thereafter. Eligible employees are automatically enrolled in the Plan at a 6% deferral rate and currently contributing employees deferral rates will be increased to 6% unless their current rate is above 6% or the employee elects to decline the automatic enrollment or increase. Effective October 1, 2013, the Plan was amended such that the Company contributed 3% of eligible payroll to the Plan for each employee and matched 100% up to 6% of employee contributions of eligible compensation. We contributed and continue to contribute in the form of cash and direct the investment to shares of AAON stock. Employees are 100% vested in salary deferral contributions and vest 20% per year at the end of years two through six of employment in employer matching contributions. The additional 3% Company contribution, a Safe-Harbor contribution, vested over two years. Effective January 1, 2016, the Plan was amended such that the Company matches 175% up to 6% of employee contributions of eligible compensation. The Company no longer contributes 3% of eligible payroll to the Plan for each employee. The Company ceased paying administrative expenses for the Plan at which time administrative expenses are paid for by Plan participants. Additionally, Plan participant forfeitures are used to reduce the cost of the Company contributions. For the years ended December 31, 2017, 2016 and 2015 we made contributions of $6.1 million, $5.9 million and $9.0 million, respectively. Administrative expenses were approximately $0, $40.0 thousand, and $0.1 million for the years ended 2017, 2016 and 2015, respectively. Profit Sharing Bonus Plan - We maintain a discretionary profit sharing bonus plan under which approximately 10% of pre-tax profit is paid to eligible employees on a quarterly basis in order to reward employee productivity. Eligible employees are regular full-time employees who are actively employed and working on the first and last days of the calendar quarter and who were employed full-time for at least three full months prior to the beginning of the calendar quarter. Profit sharing expense was $8.4 million, $9.0 million and $8.0 million for the years ended December 31, 2017, 2016 and 2015, respectively.
