4. Debt and Equity Securities

The Company’s investments in equity securities that have readily determinable fair values and all investments in debt securities are classified in one of the following three categories and accounted for accordingly: (1) trading securities, (2) securities available for sale and (3) securities held-to-maturity.

The Company did not hold any trading securities or securities held-to-maturity during the three month periods ended March 31, 2014 and December 31, 2013. Securities available for sale are recorded at fair value.

The following table summarizes the Company’s portfolio of securities available for sale at March 31, 2014:

OTTI losses on impaired securities must be fully recognized in earnings if an investor has the intent to sell the debt security or if it is more likely than not that the investor will be required to sell the debt security before recovery of its amortized cost. However, even if an investor does not expect to sell a debt security, the investor must evaluate the expected cash flows to be received and determine if a credit loss has occurred. In the event that a credit loss has occurred, only the amount of impairment associated with the credit loss is recognized in earnings in the Consolidated Statements of Income. Amounts relating to factors other than credit losses are recorded in accumulated other comprehensive income (“AOCI”) within Stockholders’ Equity.

The Company reviewed each investment that had an unrealized loss at March 31, 2014. An unrealized loss exists when the current fair value of an investment is less than its amortized cost basis. Unrealized losses on available for sale securities, that are deemed to be temporary, are recorded in AOCI, net of tax.  Unrealized losses that are considered to be other-than-temporary are split between credit related and noncredit related impairments, with the credit related impairment being recorded as a charge against earnings and the noncredit related impairment being recorded in AOCI, net of tax.

The Company evaluates its pooled trust preferred securities, included in the table above in the row labeled “Other”, using an impairment model through an independent third party, which includes evaluating the financial condition of each counterparty. For single issuer trust preferred securities, the Company evaluates the issuer’s financial condition. The Company evaluates its mortgage-backed securities by reviewing the characteristics of the securities, including delinquency and foreclosure levels, projected losses at various loss severity levels and credit enhancement and coverage. In addition, private issue CMOs are evaluated using an impairment model through an independent third party. When an OTTI is identified, the portion of the impairment that is credit related is determined by management by using the following methods: (1) for trust preferred securities, the credit related impairment is determined by using a discounted cash flow model from an independent third party, with the difference between the present value of the projected cash flows and the amortized cost basis of the security recorded as a credit related loss against earnings; (2) for mortgage-backed securities, credit related impairment is determined for each security by estimating losses based on a set of assumptions, which includes delinquency and foreclosure levels, projected losses at various loss severity levels, credit enhancement and coverage and (3) for private issue CMOs, through an impairment model from an independent third party and then recording those estimated losses as a credit related loss against earnings.

Corporate:

The unrealized losses in Corporate securities at March 31, 2014 consist of losses on six Corporate securities. The unrealized losses were caused by movements in interest rates. It is not anticipated that these securities would be settled at a price that is less than the amortized cost of the Company’s investment. Each of these securities is performing according to its terms and, in the opinion of management, will continue to perform according to its terms. The Company does not have the intent to sell these securities and it is more likely than not the Company will not be required to sell the securities before recovery of the securities’ amortized cost basis. This conclusion is based upon considering the Company’s cash and working capital requirements and contractual and regulatory obligations, none of which the Company believes would cause the sale of the securities. Therefore, the Company did not consider these investments to be other-than-temporarily impaired at March 31, 2014.

Municipal Securities:

The unrealized losses in Municipal securities at March 31, 2014, consist of losses on 24 municipal securities. The unrealized losses were caused by movements in interest rates. It is not anticipated that these securities would be settled at a price that is less than the amortized cost of the Company’s investment. Each of these securities is performing according to its terms and, in the opinion of management, will continue to perform according to its terms. The Company does not have the intent to sell these securities and it is more likely than not the Company will not be required to sell the securities before recovery of the securities amortized cost basis. This conclusion is based upon considering the Company’s cash and working capital requirements and contractual and regulatory obligations, none of which the Company believes would cause the sale of the securities. Therefore, the Company did not consider these investments to be other-than-temporarily impaired at March 31, 2014.

Other Securities:

The unrealized losses in Other Securities at March 31, 2014, consist of losses on one single issuer trust preferred security and two pooled trust preferred securities. The unrealized losses on such securities were caused by market interest volatility, a significant widening of credit spreads across markets for these securities and illiquidity and uncertainty in the financial markets. These securities are currently rated below investment grade. The pooled trust preferred securities do not have collateral that is subordinate to the classes the Company owns. The Company’s management evaluates these securities using an impairment model, through an independent third party, that is applied to debt securities. In estimating OTTI losses, management considers: (1) the length of time and the extent to which the fair value has been less than amortized cost; (2) the current interest rate environment; (3) the financial condition and near-term prospects of the issuer, if applicable; and (4) the intent and ability of the Company to retain its investment in the security for a period of time sufficient to allow for any anticipated recovery in fair value. Additionally, management reviews the financial condition of each individual issuer within the pooled trust preferred securities. All of the issuers of the underlying collateral of the pooled trust preferred securities we reviewed are banks.

For each bank, our review included the following performance items of the banks:

Ratio of tangible equity to assets

Tier 1 Risk Weighted Capital

Net interest margin

Efficiency ratio for most recent two quarters

Return on average assets for most recent two quarters

Texas Ratio (ratio of non-performing assets plus assets past due over 90 days divided by tangible equity plus the reserve for loan losses)

Credit ratings (where applicable)

Capital issuances within the past year (where applicable)

Ability to complete Federal Deposit Insurance Corporation (“FDIC”) assisted acquisitions (where applicable)

Based on the review of the above factors, we concluded that:

All of the performing issuers in our pools are well capitalized banks, and do not appear likely to be closed by their regulators.

All of the performing issuers in our pools will continue as a going concern and will not default on their securities.

In order to estimate potential future defaults and deferrals, we segregated the performing underlying issuers by their Texas Ratio. We then reviewed performing issuers with Texas Ratios in excess of 50%. The Texas Ratio is a key indicator of the health of the institution and the likelihood of failure. This ratio compares the problem assets of the institution to the institution’s available capital and reserves to absorb losses that are likely to occur in these assets. There was one issuer in our pooled trust preferred securities which had a Texas Ratio in excess of 50%. We assigned a 25% default rate to this issuer. All other issuers in our pooled trust preferred securities had a Texas Ratio below 50%.  We assigned a zero percent default rate to these issuers. Our analysis also assumed that issuers currently deferring would default with no recovery, and issuers that have defaulted will have no recovery.

We had an independent third party prepare a discounted cash flow analysis for each of these pooled trust preferred securities based on the assumptions discussed above. Other significant assumptions were: (1) two issuers totaling $26.7 million will prepay in 2014; (2) two issuers totaling $21.5 million will prepay in the second quarter of 2015; (3) senior classes will not call the debt on their portions; and (4) use of the forward London Interbank Offered Rate (“LIBOR”) curve. The cash flows were discounted at the effective rate for each security.

The Company also owns a single issue security that is carried under the fair value option, where the unrealized losses are included in the Consolidated Statements of Income – Net gain (loss) from fair value adjustments.

It is not anticipated at this time that the one single issuer trust preferred security and the two pooled trust preferred securities would be settled at a price that is less than the amortized cost of the Company’s investment. Each of these securities is performing according to its terms and, in the opinion of management and based on the review performed at March 31, 2014, will continue to perform according to its terms. The Company does not have the intent to sell these securities and it is more likely than not the Company will not be required to sell the securities before recovery of the securities’ amortized cost basis. This conclusion is based upon considering the Company’s cash and working capital requirements and contractual and regulatory obligations, none of which the Company believes would cause the sale of the securities. Therefore, the Company did not consider the one single issuer trust preferred security and the two pooled trust preferred securities to be other-than-temporarily impaired at March 31, 2014.

At March 31, 2014, the Company held four trust preferred issues which had a current credit rating of at least one rating below investment grade. One of those issues are carried under the fair value option and therefore, changes in fair value are included in the Consolidated Statement of Income – Net gain (loss) from fair value adjustments.

The following table details the remaining three trust preferred issues that were evaluated to determine if they were other-than-temporarily impaired at March 31, 2014. The class the Company owns in pooled trust preferred securities does not have any excess subordination.

REMIC and CMO:

The unrealized losses in Real Estate Mortgage Investment Conduit (“REMIC”) and CMO securities at March 31, 2014 consist of 13 issues from the Federal Home Loan Mortgage Corporation (“FHLMC”), 17 issues from the Federal National Mortgage Association (“FNMA”) and six issues from Government National Mortgage Association (“GNMA”).

The unrealized losses on the REMIC and CMO securities issued by FHLMC, FNMA and GNMA were caused by movements in interest rates. It is not anticipated that these securities would be settled at a price that is less than the amortized cost of the Company’s investment. Each of these securities is performing according to its terms, and, in the opinion of management, will continue to perform according to its terms. The Company does not have the intent to sell these securities and it is more likely than not the Company will not be required to sell the securities before recovery of the securities amortized cost basis. This conclusion is based upon considering the Company’s cash and working capital requirements, and contractual and regulatory obligations, none of which the Company believes would cause the sale of the securities.  Therefore, the Company did not consider these investments to be other-than-temporarily impaired at March 31, 2014.

GNMA:

The unrealized losses in GNMA securities at March 31, 2014 consist of losses on one security. The unrealized losses were caused by movements in interest rates.

The Company does not have the intent to sell this security and it is more likely than not the Company will not be required to sell the security before recovery of the security’s amortized cost basis. This conclusion is based upon considering the Company’s cash and working capital requirements and contractual and regulatory obligations, none of which the Company believes would cause the sale of the security.

The Company does not have the intent to sell these securities and it is more likely than not the Company will not be required to sell the securities before recovery of the securities amortized cost basis. This conclusion is based upon considering the Company’s cash and working capital requirements and contractual and regulatory obligations, none of which the Company believes will cause the sale of the securities.
