Fair values are based on quoted market prices or dealer quotes. If a quoted market price or dealer quote is not available, fair value is estimated using quoted market prices for similar securities.

In June 2014, the Company sold $375,000 of municipal bonds from a single issuer. The Company took this action under the provisions of ASC 320-10-25-6(a), which allow for the sale of held-to-maturity securities where there is “evidence of a significant deterioration in the issuer’s creditworthiness.” The resulting income statement impact was not material.

As of December 31, 2014, the Company held 264 investment securities of which 7 were in an unrealized loss position for less than twelve months. Six securities were in an unrealized loss position for twelve months or more. Management periodically evaluates each investment security for other-than-temporary impairment relying primarily on industry analyst reports and observations of market conditions and interest rate fluctuations. Management believes it will be able to collect all amounts due according to the contractual terms of the underlying investment securities.

Securities of Government Agency and Government Sponsored Entities – The unrealized losses on the Company's investments in securities of government agency and government sponsored entities were $3,000 at December 31, 2014 and $0 at December 31, 2013. The unrealized loss was caused by interest rate fluctuations. Repayment of these investments is guaranteed by an agency or government sponsored entity of the U.S. government. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost of the Company's investment. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell the securities and it is more likely than not that the Company will not have to sell the securities before recovery of their cost basis, the Company does not consider these investments to be other-than-temporarily impaired at December 31, 2014.

Mortgage Backed Securities - The unrealized losses on the Company's investment in mortgage-backed securities were $657,000 at December 31, 2014 and $7.6 million at December 31, 2013. The unrealized losses were caused by interest rate fluctuations. The contractual cash flows of these investments are guaranteed by an agency or government sponsored entity of the U.S. government. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost of the Company's investment. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell the securities and it is more likely than not that the Company will not have to sell the securities before recovery of their cost basis, the Company does not consider these investments to be other-than-temporarily impaired at December 31, 2014 or 2013.

Obligations of States and Political Subdivisions - The continuing financial problems being experienced by certain municipalities, along with the financial stresses exhibited by some of the large monoline bond insurers have increased the overall risk associated with bank-qualified municipal bonds. As of December 31, 2014, over ninety-seven percent of the Company’s bank-qualified municipal bond portfolio is rated at either the issue or the issuer level, and all of these ratings are “investment grade.” The Company monitors the status of the three percent of the portfolio that is not rated and at the current time does not believe any of them to be exhibiting financial problems that could result in a loss in any individual security.

The unrealized losses on the Company’s investment in obligation of states and political subdivision were $10,000 at December 31, 2014 and $627,000 at December 31, 2013. Management believes that any unrealized losses on the Company's investments in obligations of states and political subdivisions were caused by interest rate fluctuations. The contractual terms of these investments do not permit the issuer to settle the securities at a price less than the amortized cost of the investment. Because the Company did not intend to sell the securities and it is more likely than not that the Company would not have to sell the securities before recovery of their cost basis, the Company did not consider these investments to be other-than-temporarily impaired at December 31, 2014 and December 31, 2013.

Corporate Securities - The Company did not hold any corporate securities at December 31, 2014. The unrealized losses on the Company’s investment in corporate securities at December 31, 2013 were $147,000. Changes in the prices of corporate securities are primarily influenced by: (1) changes in market interest rates; (2) changes in perceived credit risk in the general economy or in particular industries; (3) changes in the perceived credit risk of a particular company; and (4) day to day trading supply, demand and liquidity.

Proceeds from sales and calls of securities were as follows:

Pledged Securities

As of December 31, 2014, securities carried at $178.8 million were pledged to secure public deposits, Federal Home Loan Bank (“FHLB”) borrowings, and other government agency deposits as required by law. This amount was $334.8 million at December 31, 2013.

The decrease in pledged securities in 2014 was due to the Company’s use of a $165 million standby Letter of Credit (“LC”) issued by the Federal Home Loan Bank as collateral for Public Deposits. The LC was issued December 4, 2014, and matures December 2, 2016, with a maintenance fee of 10 basis points per annum.
