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, 2017 and December 31, 2016, and the length of time they were in continuous loss positions as of such dates are as follows (in thousands):

As noted in the table above, as of March 31, 2017, the Company had unrealized losses of $3.4 million in its investment securities portfolio. The unrealized losses associated with these investment securities are driven by changes in interest rates and are recorded as a component of equity. These investment securities will continue to be monitored as a part of our ongoing impairment analysis. Management evaluates the financial performance of the issuers on a quarterly basis to determine if it is probable that the issuers can make all contractual principal and interest payments. If a shortfall in future cash flows is identified, a credit loss will be deemed to have occurred and will be recognized as a charge to earnings and a new cost basis for the security will be established.

Because the Company currently does not intend to sell any investment securities that have an unrealized loss at March 31, 2017, and it is not more-likely-than-not that we will be required to sell these investment securities before recovery of their amortized cost bases, which may be at maturity, we do not consider these securities to be other-than-temporarily impaired at March 31, 2017.

Securities with a carrying value of $120.2 million at March 31, 2017 were pledged to collateralize public deposits, derivative positions and Federal Home Loan Bank advances.

The proceeds from sales and calls of securities and the associated gains and losses are listed below:

	Three Months Ended			Three Months Ended
	March 31, 2017			March 31, 2016
Proceeds	$	5,860		$	23,195
Gross gains		—			85
Gross losses		(6	)		(46	)

The amortized cost and fair value of securities at March 31, 2017, by contractual maturity, are shown below (in thousands). Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Securities not due at a single maturity date are shown separately.
