There were no held to maturity securities in an unrealized loss position at December 31, 2012. There were no sales or transfers of held to maturity securities during 2013 and 2012.

Management evaluates securities for other-than-temporary impairment (“OTTI”) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. The investment securities portfolio is evaluated for OTTI by segregating the portfolio by type and applying the appropriate OTTI model. Investment securities classified as available for sale or held-to-maturity are generally evaluated for OTTI under ASC 320 “Investments – Debt and Equity Securities.”

In determining OTTI under the FASB ASC 320 model, management considers many factors, including: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions, and (4) whether the Company has the intent to sell the debt security or more likely than not will be required to sell the debt security before its anticipated recovery. The assessment of whether an other-than-temporary decline exists involves a high degree of subjectivity and judgment and is based on the information available to management at a point in time.

When OTTI occurs, the amount of the OTTI recognized in earnings depends on whether management intends to sell the security or it is more likely than not it will be required to sell the security before recovery of its amortized cost basis. If management intends to sell or it is more likely than not it will be required to sell the security before recovery of its amortized cost basis, the OTTI would be recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date. If management does not intend to sell the security and it is not more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis, the OTTI on debt securities would be separated into the amount representing the credit loss and the amount related to all other factors. The amount of the total OTTI related to the credit loss is determined based on the present value of cash flows expected to be collected and is recognized in earnings. The amount of the total OTTI related to other factors is recognized in other comprehensive income, net of applicable taxes. The previous amortized cost basis less the OTTI recognized in earnings becomes the new amortized cost basis of the investment.

As of June 30, 2013, the Company’s security portfolio consisted of 222 securities, 102 of which were in an unrealized loss position, and are discussed below.

U.S. government-sponsored enterprises

In the case of unrealized losses on U.S. government-sponsored enterprises, because the decline in fair value is attributable to changes in interest rates, and not credit quality, and because the Company does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery, the Company does not consider these securities to be other-than-temporarily impaired at June 30, 2013.

Mortgage-backed securities and collateralized mortgage obligations - residential

At June 30, 2013, all of the mortgage-backed securities and collateralized mortgage obligations held by the Company were issued by U.S. government-sponsored entities and agencies, primarily Ginnie Mae, Fannie Mae and Freddie Mac, institutions which the government has affirmed its commitment to support. Because the decline in fair value is attributable to changes in interest rates, and not credit quality, and because the Company does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery, the Company does not consider these securities to be other-than-temporarily impaired at June 30, 2013.

Corporate bonds

In the case of corporate bonds, the Company exposure is primarily in bonds of firms in the financial sector. All of the corporate bonds owned continue to be rated investment grade, all are current as to the payment of interest and the Company expects to collect the full amount of the principal balance at maturity. The Company actively monitors the firms and the bonds. The Company has concluded that the decline in fair value is not attributable to credit quality and because the Company does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery, the Company does not consider these securities to be other-than-temporarily impaired at June 30, 2013.

Small Business Administration (SBA) - guaranteed participation securities

At June 30, 2013, all of the SBA securities held by the Company were issued and guaranteed by U.S. Small Business Administration. Because the decline in fair value is attributable to changes in interest rates, and not credit quality, and because the Company does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery, the Company does not consider these securities to be other-than-temporarily impaired at June 30, 2013.

Mortgage-backed securities and collateralized mortgage obligations - commercial

As of June 30, 2013, all of the mortgage-backed securities and collateralized mortgage obligations held by the Company were issued by U.S. government-sponsored entities and agencies, are current as to the payment of interest and principal and the Company expects to collect the full amount of the principal and interest payments. Because the decline in fair value is attributable to changes in interest rates, and not credit quality, and because the Company does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery, the Company does not consider these securities to be other-than-temporarily impaired at June 30, 2013.

As a result of the above analysis, for the year ended June 30, 2013, the Company did not recognize any other-than-temporary impairment losses for credit or any other reason.
