Disclosure Of Compensation Related Costs Sharebased Payments [Abstract] |
Stock-Based Compensation | Note (13)—Stock-Based Compensation: The Company granted shares of common stock and restricted stock units as a part of its initial public offering and compensation arrangements for the benefit of employees, executive officers, and directors. Restricted stock unit grants are subject to time-based vesting. The total number of restricted stock units granted represents the maximum number of restricted stock units eligible to vest based upon the service conditions set forth in the grant agreements. Following the initial public offering, participants in the EBI Plans were given the option to elect conversion of their outstanding cash-settled EBI Units to stock-settled EBI Units. The following table summarizes information about vested and unvested restricted stock units outstanding at June 30, 2017:

Employee Stock Purchase Plan: In 2016, the Company adopted an employee stock purchase plan (“ESPP”) under which employees, through payroll deductions, are able to purchase shares of Company common stock. The purchase price was 85% with respect to the first offering period, and is 95% with respect to the current offering period, of the lower of the market price on the first or last day of the offering period. The maximum number of shares issuable during any offering period is 200,000 shares, and a participant may not purchase more than 725 shares during any offering period (and, in any event, no more than $25,000 worth of common stock in any calendar year). There were not any shares issued under the ESPP during the three or six months ended June 30, 2017. As of June 30, 2017 and December 31, 2016, there were 2,479,623 shares available for issuance under the ESPP.
