INCOME TAXES

Annually, we file U.S. Federal, state and foreign income tax returns.  All U.S. Federal and most state loss carryforwards remain subject to adjustment in the event of an income tax examination.
Income tax expense from continuing operations was zero for both the three months ended March 31, 2017 and 2016. We maintain a full valuation allowance on our net deferred tax assets, having concluded that we are not more likely than not going to realize the benefit of our deferred tax assets, including our net operating loss carryforwards.
