The Company also recorded $1.4 million in additional tax in 2018 after evaluating its deferred tax asset and determined that $1.4 million of the deferred tax credits may expire in 2019 and 2020 before they are fully utilized. As a result of the loss carry-forwards, the Company did not pay any income taxes in 2016, 2017 and 2018. There are no other material differences between reported income tax expense or benefit and the income tax expense or benefit that would result from applying the Federal and state statutory tax rates.
