There were twenty three and six securities with unrealized losses as of September 30, 2013 and December 31, 2012, respectively, that have been in a loss position for less than twelve months. There were no securities with unrealized losses as of September 30, 2013 and December 31, 2012 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 September 30, 2013, $45.8 million in securities, or 20%, of the investment portfolio was pledged, as compared to $42.7 million, or 20%, at December 31, 2012. We held no securities of any single issuer (other than government sponsored entities) that exceeded 10% of our shareholders’ equity at September 30, 2013 December 31, 2012.

The amortized cost and fair values of debt securities at September 30, 2013, are distributed by contractual maturity as shown below. Expected maturities may differ from contractual maturities because borrowers 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.

For the periods ending September 30, 2013 and December 31, 2012, we held Federal Home Loan Bank of Seattle (“FHLB”) stock with a book value approximately equal to its market value in the amount of $1.9 and $2.0 million, respectively. The Company evaluated its investment in FHLB stock for other-than-temporary impairment as of September 30, 2013, consistent with its accounting policy. Based on the Company’s evaluation of the underlying investment, including the fact that the FHLB of Seattle recently began redeeming stock at par, the long-term nature of the investment, the liquidity position of the FHLB of Seattle, and the Company’s intent and ability to hold the investment for a period of time sufficient to recover the par value, the Company did not recognize an other-than-temporary impairment loss.
