Investments

The investment portfolio consists primarily of U.S. Government sponsored entity and agency securities collateralized by residential mortgage obligations, private label residential mortgage backed securities (PLRMBS), and obligations of states and political subdivisions securities, all of which are classified available-for-sale. As of March 31, 2013, $92,484,000 of these securities were held as collateral for borrowing arrangements, public funds, and for other purposes.

The fair value of the available-for-sale investment portfolio reflected a net unrealized gain of $10,007,000 at March 31, 2013 compared to an unrealized gain of $12,891,000 at December 31, 2012.

We periodically evaluate each investment security for other-than-temporary impairment, relying primarily on industry analyst reports, observation of market conditions and interest rate fluctuations. Under ASC 320-10, the portion of the impairment that is attributable to a shortage in the present value of expected future cash flows relative to the amortized cost should be recorded as a current period charge to earnings. The discount rate in this analysis is the original yield expected at time of purchase.

As of March 31, 2013, the Company performed an analysis of the investment portfolio to determine whether any of the investments held in the portfolio had an other-than-temporary impairment (OTTI). Management evaluated all available-for-sale investment securities with an unrealized loss at March 31, 2013 and identified those that had an unrealized loss for at least a consecutive 12 month period, which had an unrealized loss at March 31, 2013 greater than 10% of the recorded book value on that date, or which had an unrealized loss of more than $10,000. Management also analyzed any securities that may have been downgraded by credit rating agencies. Management retained the services of a third party in March 2013 to provide independent valuation and OTTI analysis on certain private label residential mortgage backed securities (PLRMBS).

For those bonds that met the evaluation criteria, management obtained and reviewed the most recently published national credit ratings for those bonds. For those bonds that were municipal debt securities with an investment grade rating by the rating agencies, management also evaluated the financial condition of the municipality and any applicable municipal bond insurance provider and concluded that no credit related impairment existed.

The evaluation for PLRMBS includes estimating projected cash flows that the Company is likely to collect based on an assessment of all available information about the applicable security on an individual basis, the structure of the security, and certain assumptions, such as the remaining payment terms for the security, prepayment speeds, default rates, loss severity on the collateral supporting the security based on underlying loan-level borrower and loan characteristics, expected housing price changes, and interest rate assumptions, to determine whether the Company will recover the entire amortized cost basis of the security. In performing a detailed cash flow analysis, the Company identified the best estimate of the cash flows expected to be collected. If this estimate results in a present value of expected cash flows (discounted at the security’s original yield) that is less than the amortized cost basis of the security, an OTTI is considered to have occurred.

To assess whether it expects to recover the entire amortized cost basis of its PLRMBS, the Company performed a cash flow analysis for all of its PLRMBS as of March 31, 2013. In performing the cash flow analysis for each security, the Company uses a third-party model. The model considers borrower characteristics and the particular attributes of the loans underlying the Company’s securities, in conjunction with assumptions about future changes in home prices and other assumptions, to project prepayments, default rates, and loss severities.

The month-by-month projections of future loan performance are allocated to the various security classes in each securitization structure in accordance with the structure’s prescribed cash flow and loss allocation rules. When the credit enhancement for the senior securities in a securitization is derived from the presence of subordinated securities, losses are allocated first to the subordinated securities until their principal balance is reduced to zero. The projected cash flows are based on a number of assumptions and expectations, and the results of these models can vary significantly with changes in assumptions and expectations. The scenario of cash flows determined based on the model approach described above reflects a best-estimate scenario.

At each quarter end, the Company compares the present value of the cash flows expected to be collected on its PLRMBS to the amortized cost basis of the securities to determine whether a credit loss exists.

The unrealized losses associated with PLRMBS are primarily driven by projected collateral losses, credit spreads, and changes in interest rates. The Company assesses for credit impairment using a discounted cash flow model. The key assumptions include default rates, severities, discount rates and prepayment rates. Losses are estimated by forecasting the performance of the underlying mortgage loans for each security. The forecasted loan performance is used to project cash flows to the various tranches in the structure. Based upon management’s assessment of the expected credit losses of these securities given the performance of the underlying collateral compared with our credit enhancement (which occurs as a result of credit loss protection provided by subordinated tranches), the Company expects to recover the entire amortized cost basis of these securities, with the exception of certain securities for which OTTI was previously recorded.

U.S. Government Agencies

At March 31, 2013, the Company held five U.S. Government agency securities, of which two were in a loss position for less than 12 months and none were in a loss position nor had been in a loss position for 12 months or more. The unrealized losses on the Company's investments in direct obligations of U.S. government agencies were caused by interest rate changes. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized costs of the investment. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company has the ability and intent to hold those investments until a recovery of fair value, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at March 31, 2013.

Obligations of States and Political Subdivisions

At March 31, 2013, the Company held 193 obligations of states and political subdivision securities of which 36 were in a loss position for less than 12 months and none were in a loss position nor had been in a loss position for 12 months or more. The unrealized losses on the Company’s investments in obligations of states and political subdivision securities were caused by interest rate changes. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell, and it is more likely than not that it will not be required to sell those investments until a recovery of fair value, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at March 31, 2013.

U.S. Government Sponsored Entities and Agencies Collateralized by Residential Mortgage Obligations

At March 31, 2013, the Company held 179 U.S. Government sponsored entity and agency securities collateralized by residential mortgage obligations of which 33 were in a loss position for less than 12 months and 20 have been in a loss position for more than 12 months. The unrealized losses on the Company’s investments in U.S. Government sponsored entities and agencies collateralized by residential mortgage obligations were caused by interest rate changes. The contractual cash flows of those investments are guaranteed by an agency or sponsored entity of the U.S. Government. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost of the Company’s investment. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell, and it is more likely than not that it will not be required to sell those investments until a recovery of fair value, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at March 31, 2013.

Private Label Residential Mortgage Backed Securities

At March 31, 2013, the Company had a total of 22 PLRMBS with a remaining principal balance of $5,707,000 and a net unrealized gain of approximately $550,000. Four of these securities account for $68,000 of unrealized loss at March 31, 2013 offset by 18 of these securities with gains totaling $618,000. Seven of these PLRMBS with a remaining principal balance of $4,370,000 had credit ratings below investment grade. The Company continues to perform extensive analyses on these securities. No credit related OTTI charges related to PLRMBS were recorded during the three month period ended March 31, 2013.
