Management has determined that the unrealized losses at June 30, 2016 are primarily due to fluctuations in market interest rates and do not reflect credit quality deterioration of the securities. Because LCNB does not have the intent to sell the investments and it is more likely than not that LCNB will not be required to sell the investments before recovery of their amortized cost bases, which may be at maturity, LCNB does not consider these investments to be other-than-temporarily impaired.
