The tables above provide information about securities that have been in an unrealized loss position for less than twelve consecutive months and securities that have been in an unrealized loss position for twelve consecutive months or more. Management evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. Impairment is considered to be other-than-temporary if the Company (1) intends to sell the security, (2) more likely than not will be required to sell the security before recovering its cost, or (3) does not expect to recover the security’s entire amortized cost basis. Presently, the Company does not intend to sell any of these securities, does not expect to be required to sell these securities, and expects to recover the entire amortized cost of all the securities.

At March 31, 2018, there were eighty out of eighty-five U.S. agency and mortgage-backed securities, fifty-six out of eighty obligations of states and political subdivisions, and one corporate debt security in an unrealized loss position. One hundred percent of the Company’s investment portfolio is considered investment grade. The weighted-average re-pricing term of the portfolio was 5.0 years at March 31, 2018. At December 31, 2017, there were sixty-eight out of eighty-two U.S. agency and mortgage-backed securities and thirty-nine out of eighty obligations of states and political subdivisions in an unrealized loss position. One hundred percent of the Company’s investment portfolio was considered investment grade at December 31, 2017. The weighted-average re-pricing term of the portfolio was 4.7 years at December 31, 2017. The unrealized losses at March 31, 2018 in the U.S. agency and mortgage-backed securities portfolio, the obligations of states and political subdivisions portfolio, and the corporate debt securities portfolio were related to changes in market interest rates and not credit concerns of the issuers.

The amortized cost and fair value of securities at March 31, 2018 by contractual maturity are shown below (in thousands). Expected maturities of mortgage-backed securities will differ from contractual maturities because borrowers may have the right to prepay obligations with or without call or prepayment penalties.

Federal Home Loan Bank, Federal Reserve Bank and Community Bankers’ Bank stock are generally viewed as long-term investments and as restricted securities, which are carried at cost, because there is a minimal market for the stock. Therefore, when evaluating restricted securities for impairment, their value is based on the ultimate recoverability of the par value rather than by recognizing temporary declines in value. The Company does not consider these investments to be other-than-temporarily impaired at March 31, 2018, and no impairment has been recognized.

The composition of restricted securities at March 31, 2018 and December 31, 2017 was as follows (in thousands):



	March 31, 2018		December 31, 2017
Federal Home Loan Bank stock	$	665	$	645
