Net deferred tax asset	$	4,970	$	8,760

The Corporation has reported net deferred tax assets of $4.970 million at December 31, 2017. The income tax expense for 2017 was impacted by the adjustment of deferred tax assets and liabilities related to the reduction in the U.S. federal statutory income tax rate to 21% under the Tax Cuts and Jobs Act, which was enacted on December 22, 2017. As a result of the new law, and additional expense of $2.025 million was recorded in 2017. A valuation allowance is provided against deferred tax assets when it is more likely than not that some or all of the deferred tax asset will not be realized. The Corporation, as of December 31, 2017 had a net operating loss and tax credit carryforwards for tax purposes of approximately $7.5 million, and $1.7 million, respectively. The Corporation evaluated the future benefits from these carryforwards as of December 31, 2017 and determined that it was “more likely than not” that they would be utilized prior to expiration. The net operating loss carryforwards expire twenty years from the date they originated. These carryforwards, if not utilized, will begin to expire in the year 2023. A portion of the NOL and credit carryforwards are subject to the limitations for utilization as set forth in Section 382 of the Internal Revenue Code. The annual limitation is $1.537 million for the NOL and the equivalent value of tax credits, which is approximately $.476 million. These limitations for use were established in conjunction with the recapitalization of the Corporation in December 2004. The Corporation will continue to evaluate the future benefits from these carryforwards in order to determine if any adjustment to the deferred tax asset is warranted.
