Share-based Payment Arrangement [Abstract]
STOCK BASED COMPENSATION	NOTE 6 – STOCK BASED COMPENSATION We use the fair value method to account for stock-based compensation. We recorded $954,434 and $1,021,787 in compensation expense in the six months ended June 30, 2021 and 2020, respectively, related to options issued under our 2013 equity incentive plan. This includes expense related to options issued in prior years for which the requisite service period for those options includes the current period as well as options issued in the current period. The fair value of these instruments was calculated using the Black-Scholes option pricing model. There is $6,183,249 of remaining expense related to unvested options to be recognized in the future over a weighted average remaining period of approximately 2.5 years. The total intrinsic value of outstanding options at June 30, 2021 was $44,669,554. In addition to the grants to independent Directors described in Note 5 – Stockholders’ Equity, we also recorded $399,672 and $413,369 in compensation expense related to restricted stock awards that vest over time in the six months ended June 30, 2021, and 2020, respectively. There is $2,588,851 of remaining expense related to unvested restricted stock awards to be recognized in the future over a weighted average period of 3.4 years. A total of 42,374 shares related to restricted stock awards that vested in the six months ended June 30, 2020 and were issued during that same period.
