There were nine and twenty-six available-for-sale securities with unrealized losses as of June 30, 2014 and December 31, 2013, respectively, that have been in a loss position for less than twelve months. There was one security with unrealized losses as of June 30, 2014 and no securities as of December 31, 2013 that have been in an unrealized loss position for more than twelve months. The contractual terms of the investments in a loss position do not permit the issuer to settle the securities at a price less than the amortized cost of the investment. Because the Company does not intend to sell, nor is it required to sell these investments until a market price recovery or maturity, these investments are not considered other-than-temporarily impaired.

At June 30, 2014, $50.7 million in securities, or 24%, of the investment portfolio was pledged for deposits and borrowings, as compared to $46.8 million, or 19%, at December 31, 2013. We held no securities of any single issuer (other than government sponsored entities) that exceeded 10% of our shareholders’ equity at June 30, 2014 and December 31, 2013.

The amortized cost and fair values of debt securities at June 30, 2014, are distributed by contractual maturity as shown below. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. Although preferred stock has no stated maturity, it is aggregated in the calculation of weighted average yields presented below in the category of investments that mature in ten years or more.
