Securities Impairment: As a part of the Company’s ongoing security monitoring process, the Company identifies securities in an unrealized loss position that could potentially be other-than-temporarily impaired. For the three and six months ended June 30, 2019 and 2018 the Company did not record any other-than-temporary impairment (“OTTI”) losses.

The Company expects to recover its amortized cost basis on all securities in its AFS portfolio. Furthermore, the Company does not intend to sell nor does it anticipate that it will be required to sell any of its securities in an unrealized loss position as of June 30, 2019, prior to this recovery. The Company’s ability and intent to hold these securities until recovery is supported by the Company’s strong capital and liquidity positions as well as its historically low portfolio turnover.

The following summarizes, by investment security type, the basis for the conclusion that securities in an unrealized loss position were not other-than-temporarily impaired at June 30, 2019:

US Government-sponsored enterprises

249 out of the total 752 securities in the Company’s portfolios of AFS US Government-sponsored enterprises were in unrealized loss positions. Aggregate unrealized losses represented 2.0% of the amortized cost of securities in unrealized loss positions. The FNMA and FHLMC guarantee the contractual cash flows of all of the Company’s US Government-sponsored enterprises. The securities are investment grade rated and there were no material underlying credit downgrades during the quarter. All securities are performing.

US Government agency

57 out of the total 196 securities in the Company’s portfolios of AFS US Government agency securities were in unrealized loss positions. Aggregate unrealized losses represented 1.3% of the amortized cost of securities in unrealized loss positions. The Government National Mortgage Association (“GNMA”) guarantees the contractual cash flows of all of the Company’s US Government agency securities. The securities are investment grade rated and there were no material underlying credit downgrades during the quarter. All securities are performing.

Private label

Seven of the total 20 securities in the Company’s portfolio of AFS private label mortgage-backed securities were in unrealized loss positions. Aggregate unrealized losses represented 1.1% of the amortized cost of securities in unrealized loss positions. Based upon the expectation that the Company will receive all of the future contractual cash flows related to the amortized cost on these securities, the Company does not consider there to be any additional other-than-temporary impairment with respect to these securities.

Obligations of states and political subdivisions thereof

20 of the total 239 securities in the Company’s portfolio of AFS municipal bonds and obligations were in unrealized loss positions. Aggregate unrealized losses represented 2.5% of the amortized cost of securities in unrealized loss positions. The Company continually monitors the municipal bond sector of the market carefully and periodically evaluates the appropriate level of exposure to the market. At this time, the Company feels the bonds in this portfolio carry minimal risk of default and the Company is appropriately compensated for the risk. There were no material underlying credit downgrades during the quarter. All securities are performing.

Corporate bonds

Five out of the total 27 securities in the Company’s portfolio of AFS corporate bonds were in an unrealized loss position. The aggregate unrealized loss represents 2.1% of the amortized cost of bonds in unrealized loss positions. The Company reviews the financial strength of all of these bonds and has concluded that the amortized cost remains supported by the expected future cash flows of these securities.
