and in prior years, the Company performed analyses to determine if there were changes in ownership, as defined by Section
382
of the Internal Revenue Code that would limit its ability to utilize certain net operating loss and tax credit carry forwards. The Company determined that it experienced ownership changes, as defined by Section
382,
in connection with certain common stock offerings in
July 2011,
February 2013,
June 2013,
June 2015,
February 2017,
June 2017
and
October 2017.
As a result, the utilization of the Company's federal tax net operating loss carry forwards generated prior to the ownership changes are limited. As of
December 31, 2017,
the Company has net operating loss carry forwards for U.S. federal and state tax purposes of approximately
$89.0
million, before excluding net operating losses that have been limited as a result of Section
382
limitations. The annual limitation due to Section
382
for net operating loss carry forward utilization is approximately
$4.2
million per year for approximately
$90
million in net operating loss carry forwards existing at the ownership change occurring in
July 2011,
approximately
$1.4
million per year for approximately
$34
million of additional net operating losses occurring from
July 2011
to the ownership change that occurred in
February 2013,
approximately
$1.5
million per year for approximately
$4
million of additional net operating losses occurring from
February 2013
to the ownership change that occurred in
June 2013,
approximately
$1.6
million per year for approximately
$40
million of additional net operating losses occurring from
June 2013
to the ownership change that occurred in
June 2015,
approximately
$0.3
million per year for approximately
$35
million of additional net operating losses occurring from
June 2015
to the ownership change that occurred in
February 2017,
approximately
$0.3
million per year for approximately
$7
million of additional net operating losses occurring from
February 2017
to the ownership change that occurred in
June 2017
and approximately
$0.8
million per year for approximately
$5
million of additional net operating losses occurring from
June 2017
to the ownership change that occurred in
October 2017.
The utilization of these net operating loss carry forwards
may
be further limited if the Company experiences future ownership changes as defined in Section
382
of the Internal Revenue Code.
