Investments

The investment portfolio consists primarily of U.S. Government sponsored entity and agency securities collateralized by residential mortgage obligations, private label mortgage and asset backed securities (PLMABS), corporate debt securities, and obligations of states and political subdivisions securities. As of June 30, 2019, $72,924,000 of these securities were held as collateral for borrowing arrangements, public funds, and for other purposes.

The fair value of the available-for-sale investment portfolio reflected a net unrealized gain of $6,740,000 at June 30, 2019 compared to an unrealized loss of $6,257,000 at December 31, 2018. The unrealized gain/(loss) recorded is net of $1,993,000 and $(1,850,000) in tax liabilities (benefits) as accumulated other comprehensive income within shareholders’ equity at June 30, 2019 and December 31, 2018, respectively.

Losses recognized in 2019 and 2018 were incurred in order to reposition the investment securities portfolio based on the current rate environment. The securities which were sold at a loss were acquired when the rate environment was not as volatile. As market interest rates or risks associated with a security’s issuer continue to change and impact the actual or perceived values of investment securities, the Company may determine that selling these securities and using proceeds to purchase securities that fit with the Company’s current risk profile is appropriate and beneficial to the Company.

The provision for income taxes includes $1,038,000 and $265,000 income tax impact from the reclassification of unrealized net gains on securities to realized net gains on securities for the six months ended June 30, 2019 and 2018, respectively. The provision for income taxes includes $727,000 and $24,000 income tax impact from the reclassification of unrealized net gains on available-for-sale securities to realized net gains on available-for-sale securities for the three months ended June 30, 2019 and 2018, respectively.

The Company periodically evaluates each investment security for other-than-temporary impairment, relying primarily on industry analyst reports, observation of market conditions and interest rate fluctuations. The portion of the impairment that is attributable to a shortage in the present value of expected future cash flows relative to the amortized cost should be recorded as a current period charge to earnings. The discount rate in this analysis is the original yield expected at time of purchase.

As of June 30, 2019, the Company performed an analysis of the investment portfolio to determine whether any of the investments held in the portfolio had an other-than-temporary impairment (OTTI). The Company evaluated all individual available-for-sale investment securities with an unrealized loss at June 30, 2019 and identified those that had an unrealized loss for at least a consecutive 12 month period, which had an unrealized loss at June 30, 2019 greater than 10% of the recorded book value on that date, or which had an unrealized loss of more than $10,000. The Company also analyzed any securities that may have been downgraded by credit rating agencies.

For those investment securities that met the evaluation criteria, management obtained and reviewed the most recently published national credit ratings for those investment securities. For those bonds that were obligations of states and political subdivisions with an investment grade rating by the rating agencies, the Company also evaluated the financial condition of the municipality and any applicable municipal bond insurance provider and concluded there were no OTTI losses recorded during the six months ended June 30, 2019. There were no OTTI losses recorded during the six months ended June 30, 2018.

U.S. Government Agencies

At June 30, 2019, the Company held six U.S. Government agency securities of which none were in a loss position for less than 12 months and five had been in a loss position for 12 months or more. The unrealized losses on the Company’s investments in direct obligations of U.S. Government agencies were caused by interest rate changes. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized costs of the investment. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company has the ability and intent to hold, and it is more likely than not that it will not be required to sell, those investments until a recovery of fair value, which may be the maturity date, the Company does not consider those investments to be other-than-temporarily impaired at June 30, 2019.

Obligations of States and Political Subdivisions

At June 30, 2019, the Company held 28 obligations of states and political subdivision securities of which none were in a loss position.

U.S. Government Sponsored Entities and Agencies Collateralized by Residential Mortgage Obligations

At June 30, 2019, the Company held 126 U.S. Government sponsored entity and agency securities collateralized by residential mortgage obligations of which 21 were in a loss position for less than 12 months and 17 have been in a loss position for more than 12 months. The unrealized losses on the Company’s investments in U.S. Government sponsored entities and agencies collateralized by residential mortgage obligations were caused by interest rate changes. The contractual cash flows of those investments are guaranteed or supported by an agency or 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 has the ability to hold and does not intend to sell, and it is more likely than not that it will not be required to sell those investments until a recovery of fair value, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at June 30, 2019.

Private Label Mortgage and Asset Backed Securities

At June 30, 2019, the Company had a total of 47 Private Label Mortgage and Asset Backed Securities (PLMABS). Four of the PLMABS securities were in a loss position for less than 12 months and one has been in loss for more than 12 months at June 30, 2019. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company has the ability and intent to hold, and it is more likely than not that it will not be required to sell, those investments until a recovery of fair value, which may be the maturity date, the Company does not consider those investments to be other-than-temporarily impaired at June 30, 2019. The Company continues to monitor these securities for indications that declines in value, if any, may be other-than-temporary.

Corporate Debt Securities

At June 30, 2019, the Company held two corporate debt securities of which none were in a loss position.

The following tables provide a roll forward for the six months ended June 30, 2019 and 2018 of investment securities credit losses recorded in earnings.
