Income taxes
 
During the
nine
months ended
September 30, 2019,
the Company recorded a non-cash reversal to its valuation allowance of
$15,000
decreasing its valuation allowance against deferred tax assets to
$8.5
 million at
September 30, 2019.
The primary assets covered by this valuation allowance are net operating losses, which are approximately
$33.7
 million at
September 30, 2019.
The Company did
not
make any cash payments for income tax in the
three
and
nine
month periods ended
September 30, 2019
and
2018
due to its net operating loss.
 
The Company maintains a valuation allowance against deferred tax assets that currently exceed our deferred tax liabilities. The primary assets covered by this valuation allowance are net operating loss carry-forwards. The valuation allowance was calculated in accordance with the provisions of ASC
740,
Income Taxes
, which requires an assessment of both positive and negative evidence when measuring the need for a valuation allowance. The Company’s results over the most recent
four
-year period were heavily affected by business restructuring activities. The Company’s cumulative loss represented sufficient negative evidence to require a valuation allowance. The Company intends to maintain a valuation allowance until sufficient positive evidence exists to support its reversal, resulting in
no
deferred tax asset balance being recognized. Should the Company determine that it will
not
be able to realize all or part of its deferred tax asset in the future, an adjustment to the deferred tax asset will be charged to income in the period such determination is made.
 
As of
September 30, 2019
and
December 31, 2018,
the Company’s deferred tax asset balance is
$247,000
and
$494,000,
respectively.
 
The Company’s effective tax rate for the current and prior year
three
and
nine
month periods were effectively
0%
due to net operating loss carryforwards.
