Share-based Compensation Arrangement by Share-based Payment Award [Line Items]      
Award description   The Company may issue shares of common stock or grant other equity-based awards pursuant to the 2016 Equity Plan. Stock-based awards granted to date generally are time-based, vest in equal installments on each anniversary of the grant date and range over a one- to three-year period of time, and, in the case of stock options, expire 10 years from the grant date. As part of the 2016 Equity Plan, a performance equity incentive award program, known as the “Long-term incentive plan” allows participating officers of the Company to earn incentive awards of performance share/restricted stock units if certain pre-determined targets are achieved at the end of a three-year performance cycle. Stock-based compensation expense based on the grant date fair value is recognized ratably over the requisite service period for all awards and reflects forfeitures as they occur.
