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 months ended June 30, 2018 and 2017 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, 2018, 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, 2018:

Obligations of US Government-sponsored enterprises

At June 30, 2018, the one security in the Company’s portfolio of AFS US Government sponsored enterprises was in an unrealized loss position. Aggregate unrealized losses represented 0.1% of the amortized cost of securities in unrealized loss positions.The Federal National Mortgage Association (“FNMA”) and Federal Home Loan Mortgage Corporation (“FHLMC”) guarantee the contractual cash flows of all of the Company’s US Government-sponsored enterprises. The security is investment grade rated and there were no material underlying credit downgrades during the quarter. The Security is performing.

US Government-sponsored enterprises

At June 30, 2018, 495 out of the total 777 securities in the Company’s portfolios of AFS US Government-sponsored enterprises were in unrealized loss positions. Aggregate unrealized losses represented 3.2% 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

At June 30, 2018, 120 out of the total 200 securities in the Company’s portfolios of AFS US Government agency securities were in unrealized loss positions. Aggregate unrealized losses represented 3.2% 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

At June 30, 2018, ten of the total 26 securities in the Company’s portfolio of AFS private-label mortgage-backed securities were in unrealized loss positions. Aggregate unrealized losses represented 3.3% of the amortized cost of securities in unrealized loss positions. Based upon the foregoing considerations, and 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

At June 30, 2018, 119 of the total 262 securities in the Company’s portfolio of AFS municipal bonds and obligations were in unrealized loss positions. Aggregate unrealized losses represented 3.3% 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

At June 30, 2018, nine out of the total 17 securities in the Company’s portfolio of AFS corporate bonds were in an unrealized loss position. The aggregate unrealized loss represents 1.8% 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.

Visa Class B Common Shares

The Company was a member of the Visa USA payment network and was issued Class B shares in connection with the Visa Reorganization and the Visa Inc. initial public offering in March 2008. The Visa Class B shares are transferable only under limited circumstances until they can be converted into shares of the publicly traded class of Visa stock. This conversion cannot happen until the settlement of certain litigation, which is indemnified by Visa members. Since its initial public offering, Visa has funded a litigation reserve based upon a change in the conversion ratio of Visa Class B shares into Visa Class A shares. At its discretion, Visa may continue to increase the conversion rate in connection with any settlements in excess of amounts then in escrow for that purpose and reduce the conversion rate to the extent it adds any funds to the escrow in the future. Based on the existing transfer restriction and the uncertainty of the litigation, the Company has recorded its Visa Class B shares on its statements of condition at zero value for all reporting periods since 2008. At June 30, 2018, the Company owned 11,623 of Visa Class B shares with a then current conversion ratio to Visa Class A shares of 1.6298 (or 18,943 Visa Class A shares). Upon termination of the existing transfer restriction and settlement of the litigation, and to the extent the Company continues to own such Visa Class B shares in the future, the Company expects to record its Visa Class B shares at fair value.
