The $17,937,000 decrease in the Corporation’s net deferred tax asset was due a combination of a decrease in deferred tax assets and an increase in deferred tax liabilities. The largest deferred tax asset decrease was associated with the impact of the Tax Cuts and Jobs Act ("TCJA"). Signed into law on December 22, 2017, the TCJA makes permanent a reduction in the federal corporate income tax rate from 35 percent to 21 percent. Under ASC 740, the Corporation is required to adjust its net deferred tax asset at December 31, 2017 to the enacted tax rate of 21 percent. As of December 31, 2017, the Corporation has substantially completed its accounting for the tax effects of enactment of the TCJA. Tax adjustments resulted in a decrease to the net deferred tax asset of $5,120,000. The Corporation continues to analyze certain aspects of the TCJA and further refinements are possible, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. However, the Corporation does not expect these adjustments to materially impact our financial statements.

Other decreases not related to the TCJA were associated with federal and state net operating loss carryforwards and other employee benefits of $2,323,000 and $2,080,000, respectively. Increases in deferred tax liabilities associated with the accounting for acquisitions and accounting for unrealized gains on available for sale securities further decreased the net deferred tax asset by $4,106,000 and $4,273,000, respectively.

As of December 31, 2017, the Corporation has approximately $45,196,000 of state NOL carryforwards available to offset future state taxable income, which will expire beginning in 2020. These NOL carryforwards along with normal timing differences between book and tax result in total state deferred tax assets of $7,400,000. Management believes it is more likely than not that the benefit from certain of these state NOL carryforwards and certain other state deferred tax assets will not be fully realized. In recognition of this risk, the Corporation has recorded a valuation allowance of $6,966,000 against its state deferred tax assets.

The Corporation has additional paid-in capital that is considered restricted resulting from the acquisitions of CFS and Ameriana of approximately $13,393,000 and $11,883,000, respectively. CFS and Ameriana qualified as banks under provisions of the Internal Revenue Code which permitted them to deduct from taxable income an allowance for bad debts which differed from the provision for losses charged to income. No provision for income taxes had been provided. If in the future this portion of additional paid-in capital is distributed, or the Corporation no longer qualifies as a bank for income tax purposes, income taxes may be imposed at the then applicable tax rates. The unrecorded deferred tax liability at December 31, 2017, would have been approximately $5,308,000.

The Corporation or one of its subsidiaries files income tax returns in the U.S. federal jurisdiction and various state jurisdictions. The Corporation is generally no longer subject to U.S. federal, state and local income tax examinations by tax authorities for tax years before 2014.
