Stock Option Plans
 
At
December

the Company had
two
equity incentive plans. The
2005
Equity Incentive Plan
(“2005
Equity Plan”) was terminated with respect to new grants in
March
2015,
but remains in effect for grants issued prior to that time. The
2015
Equity Incentive Plan
(“2015
Equity Plan”) was approved by the Company’s Board of Directors on
January
19,
2015
and by the Company’s stockholders on
March
18,
2015.
The
2015
Equity Plan authorizes for issuance as stock options, restricted stock, stock appreciation rights, restricted stock units and performance awards, an aggregate of
5,000,000
new shares of common stock to employees, directors, advisors or consultants. At
December
31,
2016,
there were options outstanding covering
2,477,502

During the quarter ended

the Company incurred non-cash share-based compensation expense of
$307,324
resulting from the modification of stock options in accordance with a Separation Agreement and General Release related to the
June
30,
2016
departure of the Company’s prior chief executive officer (“CEO”). As per the agreement, all unvested options became fully vested on
December
31,
2016
 and shall remain exercisable for a period of
24
months following the
December
31,
2016
separation date as defined in the agreement. The expense is measured as the excess of the fair value of the modified awards over the fair value of the original awards immediately before its terms are modified as per ASC

Amended and Restated

The Company declared a dividend for the quarter ended
December
31,
2015,
which reflects a dividend yield assumption based on the expected annual yield, but the dividend was discontinued prior to the quarter ended
December
31,
2016.
Expected volatility is based on the historical volatility of the Company’s common stock over the period commensurate with the expected life of the options. The risk-free interest rate is based on rates published by the Federal Reserve Board. The expected life is based on observed and expected time to post-vesting exercise. The expected forfeiture rate is based on past experience and employee retention data. Forfeitures are estimated at the time of the grant and revised in subsequent periods if actual forfeitures differ from those estimates or if the Company updates its estimated forfeiture rate. Such amounts will be recorded as a cumulative adjustment in the period in which the estimate is changed.
 
Since the Company has an NOL carryforward as of
December
31,
2016,
no
excess tax benefit for the tax deductions related to share-based awards was recognized for the
three
months ended
December
31,
2016
and
2015.
As of
December
31,
2016,
there was approximately
$900,000
of total unrecognized compensation cost related to non-vested share-based employee compensation arrangements. The cost is expected to be recognized over a weighted-average period of
2.2
years.
