Summary of Securities with Unrealized Losses and Length of Time Continuous Loss Positions

Security fair values are established by an independent pricing service as of the dates indicated. The difference between amortized cost and fair value reflects current interest rates and represents the potential gain (loss) had the portfolio been liquidated on those dates. Security gains (losses) are realized only in the event of dispositions prior to maturity or other-than-temporary impairment. Securities with unrealized losses as of March 31, 2019 and December 31, 2018, and the length of time they were in continuous loss positions as of such dates are as follows (in thousands):
