Impairment:

The investment portfolio contained ninety-three securities with $51.1 million of temporarily impaired fair value and $820 thousand in unrealized losses at September 30, 2017. The total unrealized loss position has improved from a $1.6 million unrealized loss at year-end 2016.

For securities with an unrealized loss, Management applies a systematic methodology in order to perform an assessment of the potential for other-than-temporary impairment. In the case of debt securities, investments considered for other-than-temporary impairment: (1) had a specified maturity or repricing date; (2) were generally expected to be redeemed at par, and (3) were expected to achieve a recovery in market value within a reasonable period of time. In addition, the Bank considers whether it intends to sell these securities or whether it will be forced to sell these securities before the earlier of amortized cost recovery or maturity. Equity securities are assessed for other-than-temporary impairment based on the length of time of impairment, dollar amount of the impairment and general market and financial conditions relating to specific issues. The impairment identified on debt and equity securities and subject to assessment at September 30, 2017, was deemed to be temporary and required no further adjustments to the financial statements, unless otherwise noted.

The following table reflects temporary impairment in the investment portfolio (excluding restricted stock), aggregated by investment category, length of time that individual securities have been in a continuous unrealized loss position and the number of securities in each category as of September 30, 2017 and December 31, 2016:

The unrealized loss in the municipal bond portfolio decreased to $193 thousand from $571 thousand at December 31, 2016 as market prices improved during the quarter. There are twenty securities in this portfolio with an unrealized loss and the loss in this portfolio is deemed to be non-credit related and no other-than-temporary impairment charges have been recorded.

The trust preferred portfolio contains five securities with a fair value of $4.6 million and an unrealized loss of $187 thousand. The trust-preferred securities held by the Bank are single entity issues, not pooled trust preferred securities. Therefore, the impairment review of these securities is based only on the issuer and the security cannot be impaired by the performance of other issuers as if it was a pooled trust-preferred bond. All of the Bank’s trust preferred securities are single issue, variable rate notes with long maturities (2027 – 2028). None of these bonds have suspended or missed a dividend payment. At September 30, 2017, the Bank believes it will be able to collect all interest and principal due on these bonds and no other-than-temporary-impairment charges were recorded.

The PLMBS sector is showing an unrealized gain of $76 thousand at quarter end. This is primarily a result of the cumulative OTTI charges recorded on this portfolio. Due to the nature of these bonds, they are evaluated closely. These bonds were all rated AAA at time of purchase, but have since experienced rating declines. Some have experienced increased delinquencies and defaults, while others have seen the credit support increase as the bonds paid-down. The Bank monitors the performance of the PLMBS investments on a regular basis and reviews delinquencies, default rates, credit support levels and various cash flow stress test scenarios. In determining the credit related loss, Management considers all principal past due 60 days or more as a loss. If additional principal moves beyond 60 days past due, it will also be considered a loss. The Bank has recorded $595 thousand of cumulative impairment charges on this portfolio. Management continues to monitor these securities and it is possible that additional write-downs may occur if current loss trends continue.

The following table represents the cumulative credit losses on debt securities recognized in earnings for:

The Bank held $456 thousand of restricted stock at September 30, 2017. Except for $30 thousand, this investment represents stock in FHLB Pittsburgh. The Bank is required to hold this stock to be a member of FHLB and it is carried at cost of $100 per share. The level of FHLB stock held is determined by FHLB and is comprised of a minimum membership amount plus a variable activity amount. FHLB stock is evaluated for impairment primarily based on an assessment of the ultimate recoverability of its cost. As a government sponsored entity, FHLB has the ability to raise funding through the U.S. Treasury that can be used to support its operations. There is not a public market for FHLB stock and the benefits of FHLB membership (e.g., liquidity and low cost funding) add value to the stock beyond purely financial measures. Management intends to remain a member of the FHLB and believes that it will be able to fully recover the cost basis of this investment.
