Investment Securities | (2) Investment Securities The amortized cost and estimated fair value by type of investment security at December 31, 2013 are as follows:
The amortized cost and estimated fair value of investment securities at December 31, 2013, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to prepay obligations with or without prepayment penalties.
The amortized cost and estimated fair value by type of investment security at December 31, 2012 are as follows:
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 and because securities issued by others that are collateralized by residential mortgage-backed securities issued by Fannie Mae and Freddie Mac are rated consistently as AAA rated securities. The amortized cost and fair value of available for sale investment securities pledged to qualify for fiduciary powers, to secure public monies as required by law, repurchase agreements and short-term fixed borrowings was $2,250,755,000 and $2,264,525,000, respectively, at December 31, 2013. Proceeds from the sale and call of securities available-for-sale were $178,123,000, $1,382,231,000 and $1,102,849,000 during 2013, 2012 and 2011, respectively, which amounts included $177,623,000, $1,338,723,000 and $1,095,815,000 of mortgage-backed securities. Gross gains of $9,601,000, $38,447,000 and $17,318,000 and gross losses of $0, $1,000 and $33,000 were realized on the sales in 2013, 2012 and 2011, respectively. Gross unrealized losses on investment securities and the fair value of the related securities, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, at December 31, 2013 were as follows:
Gross unrealized losses on investment securities and the fair value of the related securities, aggregated by investment category and length of time that individual securities have been in a continuous loss position, at December 31, 2012 were as follows:
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. The contractual cash obligations of the securities issued by Ginnie Mae are fully guaranteed by the U.S. Government. The contractual cash obligations of the 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 and because securities issued by others that are collateralized by residential mortgage-backed securities issued by Fannie Mae and Freddie Mac are rated consistently as AAA rated securities. 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. An impairment charge of $1,374,000 ($893,100, after tax), was recorded in 2013 on the non-agency residential mortgage backed securities. Impairment charges of $1,039,000 ($675,000, after tax) and $977,000 ($635,000, after tax) were recorded in 2012 and 2011, respectively on the non-agency residential mortgage backed securities. The impairment charges represent 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.
