Securities Maturity Distribution: The following table summarizes the maturity distribution of the amortized cost and estimated fair value of securities available for sale as of June 30, 2016. Actual maturities may differ from the final maturities noted below because issuers may have the right to prepay or call certain securities. In the case of MBS, actual maturities may also differ from expected maturities due to the amortizing nature of the underlying mortgage collateral, and the fact that borrowers have the right to prepay.
|  | Amortized |  | Estimated
Securities Available for Sale |  | Cost |  | Fair Value
Due one year or less | $ | 167 | $ | 168
Due after one year through five years |  | 5,592 |  | 5,732
Due after five years through ten years |  | 13,889 |  | 14,762
Due after ten years |  | 495,534 |  | 511,928
Total | $ | 515,182 | $ | 532,590
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 OTTI. For the three and six months ended June 30, 2016 and 2015, the Company did not have any OTTI losses recognized in earnings (before taxes). Upon initial impairment of a security, total OTTI losses represent the excess of the amortized cost over the fair value. For subsequent impairments of the same security, total OTTI losses represent additional credit losses and or declines in fair value subsequent to the previously recorded OTTI losses, if applicable. Unrealized OTTI losses recognized in accumulated other comprehensive income ("OCI") represent the non-credit component of OTTI losses on debt securities. Net impairment losses recognized in earnings represent the credit component of OTTI losses on debt securities. As of June 30, 2016, the Company held four private label MBS (debt securities) with a total amortized cost (i.e. carrying value) of $48 for which OTTI losses have previously been recognized in pre-tax earnings dating back to the fourth quarter of 2008. For all of these securities, the Company previously recognized credit losses in excess of the unrealized losses currently in accumulated OCI, creating an unrealized gain of $135, net of tax, as included in accumulated OCI as of June 30, 2016, compared with a net unrealized gain of $462, net of tax, at December 31, 2015. The OTTI losses previously recognized in earnings represented management's best estimate of credit losses inherent in the securities based on discounted, bond-specific future cash flow projections using assumptions about cash flows associated with the pools of mortgage loans underlying each security. In estimating those cash flows the Company takes a variety of factors into consideration including, but not limited to, loan level credit characteristics, current delinquency and non-performing loan rates, current levels of subordination and credit support, recent default rates and future constant default rate estimates, original and current loan to collateral value ratios, recent collateral loss severities and future collateral loss severity estimates, recent and historical conditional prepayment rates and future conditional prepayment rate assumptions, and other estimates of future collateral performance. Despite elevated levels of delinquencies, defaults and losses in the underlying residential mortgage loan collateral, given credit enhancements resulting from the structures of the individual securities, the Company expects that as of June 30, 2016, it will recover the amortized cost basis of its private label MBS as depicted in the continuously unrealized loss table below and has therefore concluded that such securities were not OTTI as of that date. Nevertheless, given recent market conditions, it is possible that adverse changes in repayment performance and fair value could occur in future periods that would change the Company's current best estimates. The following table displays the beginning balance of OTTI related to historical credit losses on debt securities held by the Company at the beginning of the current reporting period, as well as changes in credit losses recognized in pre-tax earnings for the three and six months ending June 30, 2016, and 2015.

As of June 30, 2016, based on a review of the remaining securities in the securities portfolio, the Company concluded that it expects to recover its amortized cost basis for such securities. This conclusion was based on the issuers' continued satisfaction of the securities obligations in accordance with their contractual terms and the expectation that they will continue to do so through the maturity of the security, the expectation that the Company will receive the entire amount of future contractual cash flows, as well as the evaluation of the fundamentals of the issuers' financial condition and other objective evidence. Accordingly, the Company concluded that any declines in the values of those securities were temporary and that any additional OTTI charges were not appropriate at June 30, 2016. The following table summarizes the fair value of securities with continuous unrealized losses for less than 12 months and those that have been in a continuous unrealized loss position for 12 months or longer as of June 30, 2016 and December 31, 2015. All securities referenced are debt securities.

For securities with unrealized losses, the following information was considered in determining that the impairments were not other-than-temporary: Mortgage-backed securities issued by U.S. Government-sponsored enterprises: As of June 30, 2016, the total unrealized losses on these securities amounted to $397, compared with $2,155 at December 31, 2015. All of these securities were credit rated "AA+" by the major credit rating agencies. Company management believes these securities have minimal credit risk, as these Government-sponsored enterprises play a vital role in the nation's financial markets. Management's analysis indicates that the unrealized losses at June 30, 2016 were attributed to changes in current market yields and pricing spreads for similar securities since the date the underlying securities were purchased, and does not consider these securities to be OTTI at June 30, 2016. Mortgage-backed securities issued by U.S. Government agencies: As of June 30, 2016, the total unrealized losses on these securities amounted to $97, compared with $547 at December 31, 2015. All of these securities were credit rated "AA+" by the major credit rating agencies. Management's analysis indicates that these securities bear little or no credit risk because they are backed by the full faith and credit of the United States. The Company attributes the unrealized losses at June 30, 2016 to changes in current market yields and pricing spreads for similar securities since the date the underlying securities were purchased, and does not consider these securities to be OTTI at June 30, 2016. Private label mortgage-backed securities: As of June 30, 2016, the total unrealized losses on the Bank's private label MBS amounted to $19, compared with $11 at December 31, 2015. The Company attributes the unrealized losses at June 30, 2016 to the current illiquid market for non-agency MBS, risk-related market pricing discounts for non-agency MBS and credit rating downgrades on certain private label MBS owned by the Company. Based upon the foregoing considerations and the expectation that the Company will receive all of the future contractual cash flows related to amortized cost on these securities, the Company does not consider there to be any additional OTTI with respect to these securities at June 30, 2016. Obligations of states of the U.S. and political subdivisions thereof: As of June 30, 2016, the total unrealized losses on the Bank's municipal securities amounted to $91, compared with $328 at December 31, 2015. The Bank's municipal securities primarily consist of general obligation bonds and to a lesser extent, revenue bonds. General obligation bonds carry less risk, as they are supported by the full faith, credit and taxing authority of the issuing government and in the cases of school districts, are additionally supported by state aid. Revenue bonds are generally backed by municipal revenue streams generated through user fees or lease payments associated with specific municipal projects that have been financed. Municipal bonds are frequently supported with insurance, which guarantees that, in the event the issuer experiences financial problems, the insurer will step in and assume payment of both principal and interest. Historically, insurance support has strengthened an issuer's underlying credit rating to "AAA" or "AA" status. Starting in 2008, many of the insurance companies providing municipal bond insurance experienced financial difficulties and, accordingly, were downgraded by at least one of the major credit rating agencies. Consequently, a portion of the Bank's municipal bond portfolio was downgraded by at least one of the major credit rating agencies. Notwithstanding the credit rating downgrades, at June 30, 2016, the Bank's municipal bond portfolio did not contain any below investment grade securities as reported by major credit rating agencies. In addition, at June 30, 2016, all municipal bond issuers were current on contractually obligated interest and principal payments. The Company attributes the unrealized losses in municipal bonds at June 30, 2016 to changes in current market yields and pricing spreads for similar securities since the date the underlying securities were purchased and, to a lesser extent, changes in credit ratings on certain securities. The Company also attributes the unrealized losses to ongoing media attention and market concerns about municipal budget deficits and the prolonged recovery from the national economic recession and the impact it might have on the future financial stability of municipalities throughout the country. Notwithstanding the foregoing considerations, the Company does not consider these municipal securities to be other-than-temporarily impaired at June 30, 2016. At June 30, 2016, the Company had no intent to sell nor believed it is more-likely-than-not that it would be required to sell any of its impaired securities as identified and discussed immediately above, and therefore did not consider these securities to be other than temporarily impaired as of that date.

Visa Class B Common Shares: The Bank 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 that 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, 2016, the Bank owned 11,623 of Visa Class B shares with a then current conversion ratio to Visa Class A shares of 1.648 (or 19,158 Visa Class A shares). Upon termination of the existing transfer restriction and settlement of the litigation, and to the extent that the Bank continues to own such Visa Class B shares in the future, the Company expects to record its Visa Class A shares at fair value.
