The amortized cost and fair value of investment debt securities by contractual maturity at March 31, 2015 are shown below. Expected maturities will differ from contractual maturities because the issuers of the securities may have the right to call or prepay obligations with or without call or prepayment penalties.

We sold two available-for-sale securities in 2015 with total proceeds of $1.6 million and realized a gross gain of $8 thousand.

We sold one available-for-sale and three held-to-maturity securities in the first quarter of 2014 with total proceeds of $2.0 million and $725 thousand, respectively, and incurred a loss of $15 thousand and a gross gain of $7 thousand, respectively. The sales of the held-to-maturity securities were due to evidence of significant deterioration in issuer creditworthiness since purchase.

Investment securities carried at $69.2 million and $74.7 million at March 31, 2015 and December 31, 2014, respectively, were pledged to the State of California: $68.4 million and $73.8 million to secure public deposits in compliance with the Local Agency Security Program at March 31, 2015 and December 31, 2014, respectively, and $852 thousand and $856 thousand to provide collateral for trust deposits at March 31, 2015 and December 31, 2014, respectively. In addition, investment securities carried at $1.1 million were pledged to collateralize an internal Wealth Management and Trust Services (“WMTS”) checking account at both March 31, 2015 and December 31, 2014.

Other-Than-Temporarily Impaired Debt Securities

We have evaluated the credit of our investment securities and their issuer and/or insurers. Based on our evaluation, Management has determined that no investment security in our investment portfolio is other-than-temporarily impaired as of March 31, 2015. We do not have the intent, and it is more likely than not that we will not have to sell securities temporarily impaired at March 31, 2015 before recovery of the cost basis.

As of March 31, 2015, there were six investment positions that had been in a continuous loss position for more than twelve months. These securities consisted of a government-sponsored agency debenture, obligations of U.S. state and political subdivisions, and CMOs. We have evaluated each of the bonds and believe that the decline in fair value is primarily driven by factors other than credit. It is probable that we will be able to collect all amounts due according to the contractual terms and no other-than-temporary impairment exists on these securities. The CMOs issued by FNMA and FHLMC are supported by the U.S. Federal Government to protect us from credit losses. Additionally, the obligations of state and political subdivisions were deemed creditworthy based on our review of the issuers' recent financial information and their insurers, if any. Based upon our assessment of the credit fundamentals and the credit enhancements, we concluded that these securities were not other-than-temporarily impaired at March 31, 2015.

Six investment securities in our portfolio were in a temporary loss position for less than twelve months as of March 31, 2015. They consisted of a U.S. Agency CMO, obligations of U.S. state and political subdivisions, a corporate bond and privately issued CMOs. We determine that the strengths of GNMA through the U.S. Federal Government guarantee is sufficient to protect us from credit losses. Other temporarily impaired securities are deemed creditworthy after internal analysis. Additionally, all are rated as investment grade by at least one major rating agency. As a result of this impairment analysis, we concluded that these securities were not other-than-temporarily impaired at March 31, 2015.

Non-Marketable Securities

As a member of the FHLB, we are required to maintain a minimum investment in the FHLB capital stock determined by the Board of Directors of the FHLB. The minimum investment requirements can increase in the event we increase our total asset size or borrowings with the FHLB. Shares cannot be purchased or sold except between the FHLB and its members at its $100 per share par value. We held $8.2 million of FHLB stock recorded at cost in other assets on the consolidated statements of condition at both March 31, 2015 and December 31, 2014. The carrying amounts of these investments are reasonable estimates of fair value because the securities are restricted to member banks and they do not have a readily determinable market value. Management does not believe that the FHLB stock is other-than-temporarily-impaired, as we expect to be able to redeem this stock at cost. On April 29, 2015, the FHLB distributed a cash dividend for the first quarter of 2015 at an annualized dividend rate of 7.67%.

As a member bank of Visa U.S.A., we hold 16,939 shares of Visa Inc. Class B common stock with a carrying value of zero, which is equal to our cost basis. These shares are restricted from resale until their conversion into Class A (voting) shares upon the termination of Visa Inc.'s covered litigation escrow account. As a result of the restriction, these shares are not considered available-for-sale and are not carried at fair value. On January 28, 2015, Visa's Board of Directors approved a 4-for-1 split of Visa's Class A common stock. As Class B holders, the conversion rate was adjusted to 1.6483 when converting this Class B common stock to Class A common stock, the value would be $1.8 million at both March 31, 2015 and December 31, 2014. The conversion rate is subject to further reduction upon the final settlement of the covered litigation against Visa Inc. and its member banks. See Note 8 herein.

We invest in low income housing tax credit funds as a limited partner, which totaled $2.8 million and $1.8 million recorded in other assets as of March 31, 2015 and December 31, 2014, respectively. In the first three months of 2015, we recognized $72 thousand of low income housing tax credits and other tax benefits, net of $56 thousand of amortization expense of low income housing tax credit investment, as a component of income tax benefit. As of March 31, 2015, our unfunded commitments for these low income housing tax credit funds totaled $2.2 million. We did not recognize any impairment losses on these low income housing tax credit investments during the first three months of 2015, or the year ended December 31, 2014.
