During the third quarter of 2014, the Company sold one security from the available for sale portfolio with a total fair market value of $10.7 million. The Company had no securities that were called by their respective issuers. The Company realized a securities gain of $26,000 on the sale.

During the third quarter of 2013, the Company did not sell any securities and had no securities that were called by their respective issuers.

During the first nine months of 2014, the Company sold two securities with a total fair market value of $11.3 million and realized total net gains of $37,000. One security was from the held to maturity (HTM) portfolio, however, it was an amortizing security that had already returned more than 85% of its principal and could be sold without tainting the remaining HTM portfolio. The Company had no securities that were called by their respective issuers.

During the first nine months of 2013, the Company sold 21 securities with a total fair market value of $89.9 million. The Company also had $50.0 million of agency debentures that were called by their respective issuers. In total, the Company realized net security gains of $21,000. Of the investments sold, five were from the HTM portfolio, four of which were amortizing securities that had already returned at least 85% of their respective principal, and one of which was a corporate bond within three months of its maturity date. In all cases, these could be sold without tainting the remaining HTM portfolio.

The Company does not maintain a trading portfolio and there were no transfers of securities between the available for sale (AFS) and HTM portfolios. The Company uses the specific identification method to record security sales.

At September 30, 2014, securities with a carrying value of $666.1 million were pledged to secure public deposits and for other purposes as required or permitted by law.

In determining fair market values for its portfolio holdings, the Company receives information from a third party provider which management evaluates and corroborates using amounts from one of its securities brokers. Under the current guidance, these values are considered Level 2 inputs, based upon mathematically derived matrix pricing and observed data from similar assets. They are not Level 1 direct quotes, nor do they reflect Level 3 inputs that would be derived from internal analysis or judgment. As the Company does not manage a trading portfolio and typically only sells from its AFS portfolio in order to manage interest rate risk or credit exposure, direct quotes, or street bids, are warranted on an as-needed basis.

The following table shows the fair value and gross unrealized losses associated with the Company's investment portfolio, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position:

The Company's investment securities portfolio consists of U.S. Government agency debentures, U.S. Government sponsored agency mortgage-backed securities (MBSs), agency collateralized mortgage obligations (CMOs), corporate bonds and municipal bonds. The Company considers securities of the U.S. Government sponsored agencies and the U.S. Government MBS/CMOs to have little credit risk because their principal and interest payments are backed by an agency of the U.S. Government.

The unrealized losses in the Company's investment portfolio at September 30, 2014 were associated with two distinct types of securities. The first type, those backed by the U.S. Government or one of its agencies, included 11 debentures, 43 CMOs and 11 MBSs. Management believes that the unrealized losses on these investments were primarily caused by the movement of interest rates from the date of purchase and notes the contractual cash flows of those investments are guaranteed by an agency 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. The Company also owns nine municipal bonds that were in an unrealized loss position as of September 30, 2014. In all cases, the bonds are general obligations of either a Pennsylvania municipality or school district and are backed by the ad valorem taxing power of the entity. In all cases, the bonds carry an investment grade rating of no lower than single-A by either Moody's or Standard and Poors. The Company, however, conducts its own periodic, independent review and believes the unrealized losses in its municipal bond portfolio are the result of movements in long-term interest rates and are not reflective of any credit deterioration. The Company does not intend to sell these debt securities prior to recovery and it is more likely than not that the Company will not have to sell these debt securities prior to recovery.

The Company did not incur any OTTI credit losses during either the three or nine months ended September 30, 2014 or 2013.
