STOCK BASED COMPENSATION [Abstract] |
STOCK BASED COMPENSATION | NOTE 7 – STOCK BASED COMPENSATION ﻿ Stock Based Compensation – The Company utilizes three types of equity awards: restricted stock awards (“RSAs”), restricted stock units (“RSUs”) and performance based restricted stock units (“PSUs”) see Note 2 – Summary of Significant Accounting Policies. The Company adopted ASU 2016-09 – Compensation - Stock Compensation (Topic 718) on September 1, 2017, see Note 1 – Company Overview and Basis of Presentation for more information on the implementation. The Company adopted the 2013 Equity Incentive Award Plan (the "2013 Plan") for the benefit of its eligible employees, consultants and non-employee directors on January 22, 2013. The 2013 Plan provides for awards covering up to (1) 600,000 shares of common stock plus (2) the number of shares that remained available for issuance as of January 22, 2013 under three equity participation plans previously maintained by the Company. The number of shares reserved for issuance under the 2013 Plan increases during the term of the plan by the number of shares relating to awards outstanding under the 2013 Plan or any of the prior plans that expire, or are forfeited, terminated, canceled or repurchased, or are settled in cash in lieu of shares. However, in no event will more than an aggregate of 951,741 shares of the Company’s common stock be issued under the 2013 Plan.

﻿ At the vesting dates for restricted stock awards to employees, the Company repurchases a portion of the shares that have vested at the prior day's closing price per share, with the funds used to pay the employees' minimum statutory tax withholding requirements related to the vesting of restricted stock awards. The Company expects to continue this practice going forward.
