)  Federal Income Taxes
Deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be reversed. The Corporation and the Bank file a consolidated
federal income tax return.

In accordance with ASC
740,
the Company is required to establish a
valuation allowance for deferred tax assets when it is “more likely than
not”
that a portion or the entire deferred tax asset will
not
be realized. The evaluation requires significant judgment and extensive analysis of all available positive and negative evidence, the forecast of future income, applicable tax planning strategies, and assessments of current and future economic and business conditions. The Company did
not
maintain a valuation allowance on its deferred tax assets during the years ended
December 31, 2017,
2016,
and
2015.
 
In the ordinary course of business, the Company enters into certain transactions that have tax consequences. From time to time, the Internal Revenue Service (IRS) questions and/or challenges the tax positions taken by the Company with respect to those transactions. The Comp
any believes that its tax returns were filed based upon applicable statutes, regulations, and case law in effect at the time of the transactions. The IRS, an administrative authority of a court, if presented with the transactions could disagree with the Company’s interpretation of the tax law.
 
In the
fourth
quarter of
2015
the
Company agreed to a settlement with the IRS for an audit of its tax returns filed for the
2004,
2005,
2007,
2008,
2009
and
2010
tax years. That settlement was approved by Congress’ Joint Committee on Taxation in
2016.
The Company remitted the taxes and interest required by the settlement and the audit is closed.
