Note 6 - Investment Securities

 

The Company classifies debt and equity securities into one of three categories:  held-to maturity, available-for-sale, or trading.  Such securities are reassessed for appropriate classification at each reporting date.  Securities classified as “held-to-maturity” are carried at amortized cost for financial statement reporting, while securities classified as “available-for-sale” and “trading” are carried at their fair value.  Unrealized holding gains and losses are included in net income for those securities classified as “trading”, while unrealized holding gains and losses related to those securities classified as “available-for-sale” are excluded from net income and reported net of tax as other comprehensive income (loss) and accumulated other comprehensive income (loss) until realized, or in the case of losses, when deemed other than temporary.

Residential mortgage-backed securities are securities issued by Freddie Mac, Fannie Mae, Ginnie Mae or non-government entities.  Investments in residential mortgage-backed securities issued by Ginnie Mae are fully guaranteed by the U.S. Government.  Investments in mortgage-backed securities issued by Freddie Mac and Fannie Mae are not fully guaranteed by the U.S. Government, however, the Company believes that the quality of the bonds is similar to other AAA rated bonds with limited credit risk, particularly given the placement of Fannie Mae and Freddie Mac into conservatorship by the federal government in early September 2008.

The unrealized losses on investments in residential mortgage-backed securities are primarily caused by changes in market interest rates.  Residential mortgage-backed securities are primarily securities issued by Freddie Mac, Fannie Mae and Ginnie Mae.  Investments in mortgage-backed securities issued by Ginnie Mae are fully guaranteed by the U.S. Government.  Investments in mortgage-backed securities issued by Freddie Mac and Fannie Mae are not fully guaranteed by the U.S. Government; however, the Company believes the quality of the bonds is similar to other AAA rated bonds with limited credit risk, particularly given the placement of Fannie Mae and Freddie Mac into conservatorship by the federal government in early September 2008.  The decrease in fair value on residential mortgage-backed securities issued by Freddie Mac, Fannie Mae and Ginnie Mae is due to market interest rates.  The Company has no intent to sell and will more than likely not be required to sell before a market price recovery or maturity of the securities; therefore, it is the conclusion of the Company that the investments in residential mortgage-backed securities issued by Freddie Mac, Fannie Mae and Ginnie Mae are not considered other-than-temporarily impaired.  In addition, the Company has a small investment in non-agency residential mortgage-backed securities that have strong credit backgrounds and include additional credit enhancements to protect the Company from losses arising from high foreclosure rates.  These securities have additional market volatility beyond economically induced interest rate events.  It is the conclusion of the Company that the investments in non-agency residential mortgage-backed securities are other-than-temporarily impaired due to both credit and other than credit issues.  Impairment charges of $239,000 ($155,350, after tax) and $647,000 ($420,550, after tax) were recorded for the three and nine months ended September 30, 2012. Impairment charges of $286,000 ($185,900, after tax) and $701,000 ($455,650, after tax) were recorded for the three and nine months ended September 30, 2011. The impairment charge represents the credit related impairment on the securities.

 

The unrealized losses on investments in other securities are caused by fluctuations in market interest rates.  The underlying cash obligations of the securities are guaranteed by the entity underwriting the debt instrument.  It is the belief of the Company that the entity issuing the debt will honor its interest payment schedule, as well as the full debt at maturity.  The securities are purchased by the Company for their economic value.  The decrease in fair value is primarily due to market interest rates and not other factors, and because the Company has no intent to sell and will more than likely not be required to sell before a market price recovery or maturity of the securities, it is the conclusion of the Company that the investments are not considered other-than-temporarily impaired.
