December
31,
2016
was
$1.95
as reported by the NASDAQ Capital Market. The aggregate intrinsic value of stock options outstanding at
December
31,
2016
and
2015
was
$0.7
million and
$0,
respectively. The aggregate intrinsic value of restricted stock units outstanding at
December
31,
2016
and
2015
was
$0.3
million and
$0.7
million, respectively.

 Upon the departure of our CEO in
June
2015,
a nominal amount of previously recognized stock-based compensation expense was reversed due to the forfeiture of stock option grants. As of
December
31,
2016,
the unrecorded stock-based compensation balance related to stock options and restricted stock units outstanding excluding estimated forfeitures was
$3.8
million and
$0.8
million, respectively, and will be recognized over an estimated weighted average amortization period of
2.88
years for stock options and
1.54
years for restricted stock units. The amortization period is based on the expected remaining vesting term of the options and restricted stock units.

Employee Stock Purchase Plan (“ESPP”)
 
The price paid for the Company’s common stock purchased under the ESPP is equal to
85%
of the lower of the fair market value of the Company’s common stock at the beginning of each offering period or at the end of each offering period. The compensation expense in connection with the ESPP for the
three
months ended
December
31,
2016
and
2015
was
$21,000
and
$21,300,
respectively, and approximately
$70,000
and
$55,000
for the
nine
months ended
December
31,
2016
and
2015,
respectively. During the
nine
months ended
December
31,
2016
and
2015,
there were
46,604
and
24,115
shares issued under the ESPP, respectively.
