On
December 22, 2017,
the Tax Cuts and Jobs Act (“
Act”) was signed into law. Among other changes is a permanent reduction in the federal corporate income tax rate from
35%
to
21%
effective
January 1, 2018. 
As a result of the reduction in the corporate income tax rate, the Company revalued its net deferred tax asset at
December 31, 2017.
This results in a reduction in the value of the Company’s net deferred tax asset of approximately
$10.9
million, which was fully offset by the change in valuation allowance.
 
On
December 22, 2017,
the SEC staff issued Staff Accounting Bulletin
No.
118
(SAB
118
) to the accounting for certain income tax effects of the Act. The Company has computed reasonable estimates related t
o the income tax effects of the Act. The Company has considered tax law changes effective
2018.
The Company is reporting the estimates as a provisional amount in its financial statements for which the accounting under ASC 
740
is completed. Primarily due to the lack state issued guidance, the Company will finalize the calculation in
2018.
The Company does
not
expect tax reform legislation to have a significant impact on the results of operations.
 
A valuation allowance has been recorded for the entire amou
nt of the Company’s deferred tax assets as a result of uncertainties regarding the realization of the deferred tax assets. The change in the valuation allowance totaled
$0.3
million,
$7.4
million and 
$4.0
million for the years ended
December 
31,
2017,
2016,
and
2015,
respectively, principally due to increases in the valuation allowance associated with increased net operating losses. The
2017
change is primarily due to the change in the valuation allowance caused by tax effects of the current year net operating loss (“NOL”),
$10.7
million, which is offset by the
$10.9
 million tax charge related to remeasurement of the deferred tax assets.
 
As of
December
 
31,
2017,
the Company had NOL carryforwards for federal, state and Australian income tax reporting purposes of approximately
$91.9
 million,
$56.4[JS1]
  million, and
$6.5
million, respectively. As of
December 
31,
2017,
the Company also had Federal and California research and development tax credit carryforwards of approximately
$0.8
 million and
$0.7
million, respectively. The Federal NOL and tax credit carryforwards will expire at various dates beginning in
2025
through
2037.
The California NOL carryforwards will expire at various dates beginning in
2028
 through
2037.
The California research and development tax credit carryforwards are carried forward indefinitely. Subject to continuity of ownership requirements, Australian NOL are carried forward indefinitely.
 
Pursuant to Internal Revenue Code Sections
382
and
383,
annual use of the Company
’s NOL and tax credit carryforwards
may
be limited in the event a cumulative change in ownership of more than
50%
occurs within a
three
-year period. The Company has
not
completed a study to assess whether an ownership change has occurred or whether there have been multiple ownership changes since the Company’s formation, primarily due to the complexity and cost associated with such a study; and the possibility that there
may
be additional ownership changes in the future. If the Company has experienced an ownership change, the utilization of the NOL or tax credit carryforwards to offset future taxable income and taxes, respectively, would be subject to an annual limitation. Any limitation
may
effectively eliminate of all or a portion of the NOL or tax credit carryforwards before utilization.
 
The Company maintains a full valuation allowance for its deferred tax assets due to it
s historical losses and uncertainties surrounding its ability to generate future taxable income to realize these assets. Due to the existence of the valuation allowance, future changes in any unrecognized tax benefits and recognizable deferred tax benefits after the completion of an ownership change analysis is
not
expected to impact its effective tax rate.

will remain open for examination by the federal, state and foreign tax authorities for
three
and

years, respectively, from the date of utilization of any net operating loss or tax credits. The Company is
not
currently subject to income tax examinations by any authority.
