For purposes of the maturity table, mortgage-backed securities, which are

not

due at a single maturity date, have been allocated over maturity groupings based on the weighted-average contractual maturities of underlying collateral. The mortgage-backed securities generally mature earlier than their weighted-average contractual maturities because of principal prepayments.

The following table reflects gross unrealized losses and fair value, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, as of

September 30, 2017

and

December 31, 2016.

Management evaluates securities for other-than-temporary impairment

less frequently than quarterly, and more frequently when economic or market concerns warrant such evaluation. Consideration is given to: (i) the length of time and the extent to which fair value has been less than cost, (ii) the financial condition and near-term prospects of the issuer, (iii) whether the Company intends to sell securities, and (iv) whether it is more likely than

not

that the Company will be required to sell the securities before recovery of their amortized cost bases.

As of

September

30,

2017,

debt securities had been in a loss position for more than

months, and

debt securities had been in a loss position for less than

months. As of

December 31, 2016,

debt securities had been in a loss position for more than

months, and

130

debt securities had been in a loss position for less than

months. As of both

September 30, 2017

and

December 31, 2016,

the losses for all securities were considered to be a direct result of the effect that the prevailing interest rate environment had on the value of debt securities and were

not

related to the creditworthiness of the issuers. Further, the Company has the current intent and ability to retain its investments in the issuers for a period of time that management believes to be sufficient to allow for any anticipated recovery in fair value. Therefore, the Company did

not

recognize any other-than-temporary impairments as of

September 30,

2017

and

December 31, 2016.

Investment securities available-for-sale with a carrying value of

$87.1

million and

$87.7

million as of

September 30,

2017

and

December 31, 2016,

respectively, were pledged to secure public deposits and for other purposes.
