INCOME TAXES
 
Our effective tax rate for the
six
-month periods ended
June 30, 2019
and
July 1, 2018
was
20.8%
and
3.4%,
respectively. The increase in our effective tax rate for the current period compared to the prior period was primarily due to the reversal of the valuation allowance on our U.S. deferred tax assets as of
December 31, 2018.
 
Our effective tax rate for the
six
months ended
June 30, 2019
was lower than the U.S. federal statutory rate primarily due to tax benefits relating to the exercise of stock options during the period.
 
As of
December 31, 2018,
we have domestic net operating loss (“NOL”) carryforwards of
$63,388,
which expire
2019
thru
2035,
and domestic tax credits of
$1,817,
which expire
2028
thru
2037,
available to reduce future taxable income. Management has concluded it is more likely than
not
that these domestic NOL and credit carryforwards will be fully utilized.
 
As of
June 30, 2019,
for certain past operations in the U.K., we continue to report a valuation allowance for NOL carryforwards of approximately
$10,000,
nearly all of which can be carried forward indefinitely. Utilization of the net operating losses
may
be limited due to the change in the past U.K. operation and cannot currently be used to reduce taxable income at our other U.K. subsidiary, Accutronics Ltd.
 
As of
June 30, 2019,
we have
not
recognized a valuation allowance against our other foreign deferred tax assets, as realization is considered to be more likely than
not.
 
As of
June 30, 2019,
the Company maintains its assertion that all foreign earnings will be indefinitely reinvested in those operations.
 
There were
no
unrecognized tax benefits related to uncertain tax positions at
June 30, 2019
and
December 31, 2018.
 
As a result of our operations, we file income tax returns in various jurisdictions including U.S. federal, U.S. state and foreign jurisdictions. We are routinely subject to examination by taxing authorities in these various jurisdictions. Our U.S. tax matters for the years
2000
through
2018
remain subject to examination by the Internal Revenue Service (“IRS”) due to our net operating loss carryforwards. Our U.S. tax matters for the years
2000
through
2018
remain subject to examination by various state and local tax jurisdictions due to our net operating loss carryforwards. Our tax matters for the years
2010
through
2018
remain subject to examination by the respective foreign tax jurisdiction authorities.
