- Stock-Based Compensation; Changes in Equity
 
The Company has adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic
718
which requires all share-based payments to employees, including grants of employee stock options, to be recognized in the condensed consolidated financial statements based on their grant-date fair values.
 
The Company has applied the Black-Scholes model to value stock-based awards and issued warrants related to notes payable. That model incorporates various assumptions in the valuation of stock-based awards relating to the risk-free rate of interest to be applied, the estimated dividend yield and expected volatility of our common stock. The risk-free rate of interest is the related U.S. Treasury yield curve for periods within the expected term of the option at the time of grant. The dividend yield on our common stock is estimated to be
0%,
as the Company did
not
issue dividends during
2018
and
2017.
The expected volatility is based on historical volatility of the Company’s common stock.
 
The Company’s net loss for the
three
months ended
March 31, 2018
and
2017
includes approximately
$62,000
and
$5,000,
respectively, of compensation costs related to share based payments. As of
March 31, 2018,
there is
$302,000
of unrecognized compensation expense related to non-vested stock option grants and stock grants. We expect approximately
$110,000
of additional stock-based compensation expense to be recognized over the remainder of
2018,
$92,000
to be recognized during
2019,
and
$56,000
to be recognized during
2020.
 
On
April 10, 2009,
the Board of Directors approved for adoption, and on
June 5, 2009,
the shareholders of the Corporation approved, a
2009
Stock Incentive Plan (
“2009
Plan”). The
2009
Plan and subsequent awards categorized as inducement of employment authorized the issuance of up to
510,000
shares of stock or options to purchase stock of the Company (including cancelled shares reissued under the plan.) As of
March 31, 2018,
all underlying awards had been granted and options for
471,144
shares remain outstanding.

$37,000,
which represents the total pre-tax intrinsic value (the difference between the closing price of the Company’s common stock on the last trading day of the quarter ended
March 31, 2018
and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all the holders exercised their options on
