The decrease in effective tax rate from
2015
to
2016
was primarily the result of higher utilization of tax credits in
2016.
Bancorp invests in certain partnerships that yield federal income tax credits. The tax benefit of these investments exceeds the amortization expense associated with them, resulting in a positive impact on income. The increase in the effective tax rate from
2014
to
2015
was the result of lower nontaxable income from municipal securities.
 
The effects of temporary differences that gave rise to significant portions of deferred tax assets and deferred tax liabilities follows:

A valuation allowance is recognized for a deferred tax asset if, based on the weight of available evidence, it is more-likely-than-not that some portion of the entire deferred tax asset will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projection for future taxable income over the periods which the temporary differences resulting in the remaining deferred tax assets are deductible, management believes it is more-likely-than-not that Bancorp will realize the benefits of these deductible differences, net of the valuation allowance, at
December
31,
2016.
 
Realization of deferred tax assets associated with the investment in tax credit partnerships is dependent upon generating sufficient taxable capital gain income prior to their expiration. A valuation allowance to reflect management’s estimate of the temporary deductible differences that
may
expire prior to their utilization has been recorded as of
December
31,
2016
and
2015.
 
US GAAP provides guidance on financial statement recognition and measurement of tax positions taken, or expected to be taken, in tax returns. As
December
31,
2016
and
2015,
the gross amount of unrecognized tax benefits, including penalties and interest, was
$40
thousand. If recognized, tax benefits would reduce tax expense and accordingly, increase net income. The amount of unrecognized tax benefits
may
increase or decrease in the future for various reasons including adding amounts for current year tax positions, expiration of open income tax returns due to statutes of limitation, changes in management’s judgment about the level of uncertainty, status of examination, litigation and legislative activity and addition or elimination of uncertain tax positions. Federal and state income tax returns are subject to examination for the years after
2011.
 
A reconciliation of the amount of unrecognized tax benefits follows:
