Other securities. At December 31, 2012, there were four pooled trust preferred securities with an estimated fair value of $393,000 and unrealized losses of $1.2 million in a continuous unrealized loss position for twelve months or more. These unrealized losses were primarily due to the long-term nature of the pooled trust preferred securities, a lack of demand or inactive market for these securities, and concerns regarding the financial institutions that have issued the underlying trust preferred securities.

The December 31, 2012, cash flow analysis for three of these securities showed it is probable the Company will receive all contracted principal and related interest projected. The cash flow analysis used in making this determination was based on anticipated default and recovery rates, amounts of prepayments, and the resulting cash flows were discounted based on the yield anticipated at the time the securities were purchased. Other inputs include the actual collateral attributes, which include credit ratings and other performance indicators of the underlying financial institutions, including profitability, capital ratios, and asset quality. Assumptions for these three securities included prepayments by banks of $15 billion or more in assets of all fixed rate securities during 2013; adjustable rate securities are expected to prepay based on spreads. For banks of less than $15 billion in assets, the only material prepayments are assumed to be those by issuers with strong capital positions and with relatively high fixed rates. No recoveries are assumed for issuers currently in default; recoveries of 29% to 44% on currently deferred issuers within the next two years; no net new deferrals for the next two years; and annual defaults of 36 basis points (with 10% recoveries, lagged two years) thereafter.

One of these three securities continues to receive cash interest payments in full and our cash flow analysis indicates that these payments are likely to continue. Because the Company does not intend to sell this security and it is not more-likely-than-not that the Company will be required to sell the security prior to recovery of its amortized cost basis, which may be maturity, the Company does not consider this investment to be other-than-temporarily impaired at December 31, 2012.

For the other two of these three securities, the Company is receiving principal-in-kind (PIK), in lieu of cash interest. These securities allow, under the terms of the issue, for issuers to defer interest for up to five consecutive years. After five years, if not cured, the securities are considered to be in default and the trustee may demand payment in full of principal and accrued interest. Issuers are also considered to be in default in the event of the failure of the issuer or a subsidiary. Both deferred and defaulted issuers are considered non-performing, and the trustee calculates, on a quarterly or semi-annual basis, certain coverage tests prior to the payment of cash interest to owners of the various tranches of the securities. The tests must show that performing collateral is sufficient to meet requirements for senior tranches, both in terms of cash flow and collateral value, before cash interest can be paid to subordinate tranches. If the tests are not met, available cash flow is diverted to pay down the principal balance of senior tranches until the coverage tests are met, before cash interest payments to subordinate tranches may resume. The Company is receiving PIK for these two securities due to failure of the required coverage tests described above at senior tranche levels of these securities. The risk to holders of a tranche of a security in PIK status is that the pool’s total cash flow will not be sufficient to repay all principal and accrued interest related to the investment. The impact of payment of PIK to subordinate tranches is to strengthen the position of senior tranches, by reducing the senior tranches’ principal balances relative to available collateral and cash flow, while increasing principal balances, decreasing cash flow, and increasing credit risk to the tranches receiving PIK. For our securities in receipt of PIK, the principal balance is increasing, cash flow has stopped, and, as a result, credit risk is increasing. The Company expects these securities to remain in PIK status for a period of four to five years. Despite these facts, because the Company does not intend to sell these two securities and it is not more-likely-than-not that the Company will be required to sell these two securities prior to recovery of their amortized cost bases, which may be maturity, the Company does not consider these investments to be other-than-temporarily impaired at December 31, 2012.

At December 31, 2008, analysis of the fourth pooled trust preferred security indicated other-than-temporary impairment (OTTI) and the Company performed further analysis to determine the portion of the loss that was related to credit conditions of the underlying issuers. The credit loss was calculated by comparing expected discounted cash flows based on performance indicators of the underlying assets in the security to the carrying value of the investment. The discounted cash flow was based on anticipated default and recovery rates, and resulting projected cash flows were discounted based on the yield anticipated at the time the security was purchased. Based on this analysis, the Company recorded an impairment charge of $375,000 for the credit portion of the unrealized loss for this trust preferred security. This loss established a new, lower amortized cost basis of $125,000 for this security, and reduced non-interest income for the second quarter and the twelve months ended June 30, 2009. At December 31, 2012, cash flow analyses showed it is probable the Company will receive all of the remaining cost basis and related interest projected for the security. The cash flow analysis used in making this determination was based similar inputs and factors as those described above. Assumptions for this security included prepayments by banks of $15 billion or more in assets of all fixed rate securities during 2013; adjustable rate securities are expected to prepay based on spreads. For banks of less than $15 billion in assets, the only material prepayments are assumed to be those with relatively high fixed rates. No recoveries are assumed for issuers currently in default; recoveries of 49% on currently deferred issuers within the next two years; no net new deferrals for the next two years; and annual defaults of 36 basis points (with 10% recoveries, lagged two years) thereafter. This security is in PIK status due to similar criteria and factors as those described above, with similar impact to the Company. This security is projected to remain in PIK status for a period of two years. Because the Company does not intend to sell this security and it is not more-likely-than-not the Company will be required to sell this security before recovery of its new, lower amortized cost basis, which may be maturity, the Company does not consider the remainder of the investment in this security to be other-than-temporarily impaired at December 31, 2012.

The Company does not believe any other individual unrealized loss as of December 31, 2012, represents OTTI. However, given the continued disruption in the financial markets, the Company may be required to recognize OTTI losses in future periods with respect to its available for sale investment securities portfolio. The amount and timing of any additional OTTI will depend on the decline in the underlying cash flows of the securities. Should the impairment of any of these securities become other-than-temporary, the cost basis of the investment will be reduced and the resulting loss recognized in the period the other-than-temporary impairment is identified.

Credit losses recognized on investments. As described above, some of the Company’s investments in trust preferred securities have experienced fair value deterioration due to credit losses, but are not otherwise other-than-temporarily impaired. During fiscal 2009, the Company adopted ASC 820, formerly FASB Staff Position 157-4, “Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly.” The following table provides information about the trust preferred security for which only a credit loss was recognized in income and other losses are recorded in other comprehensive income (loss) for the six-month periods ended December 31, 2012 and 2011.
