The weighted average yield on investment securities available-for-sale is based on amortized cost; therefore, it does not give effect to changes in fair value.

Securities not due on a single contractual maturity date, such as mortgage-backed securities and collateralized mortgage obligations, are classified in the period of final contractual maturity. The expected maturities of collateralized mortgage obligations, mortgage-backed securities and certain other securities may differ from their contractual maturities because they may be subject to prepayments or may be called by the issuer.

There were no securities sold during the quarters ended March 31, 2012 and 2011.

 

The following tables present the Corporation's fair value and gross unrealized losses of investment securities available-for-sale, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position.

Management evaluates investment securities for other-than-temporary (“OTTI”) declines in fair value on a quarterly basis. Once a decline in value is determined to be other-than-temporary, the value of a debt security is reduced and a corresponding charge to earnings is recognized for anticipated credit losses. Also, for equity securities that are considered other-than-temporarily impaired, the excess of the security's carrying value over its fair value at the evaluation date is accounted for as a loss in the results of operations. The OTTI analysis requires management to consider various factors, which include, but are not limited to: (1) the length of time and the extent to which fair value has been less than the amortized cost basis, (2) the financial condition of the issuer or issuers, (3) actual collateral attributes, (4) the payment structure of the debt security and the likelihood of the issuer being able to make payments, (5) any rating changes by a rating agency, (6) adverse conditions specifically related to the security, industry, or a geographic area, and (7) management's intent to sell the debt security or whether it is more likely than not that the Corporation would be required to sell the debt security before a forecasted recovery occurs.

At March 31, 2012, management performed its quarterly analysis of all debt securities in an unrealized loss position. Based on the analyses performed, management concluded that no individual debt security was other-than-temporarily impaired as of such date. At March 31, 2012, the Corporation did not have the intent to sell debt securities in an unrealized loss position and it is not more likely than not that the Corporation will have to sell the investment securities prior to recovery of their amortized cost basis. Also, management evaluated the Corporation's portfolio of equity securities at March 31, 2012. No other-than-temporary impairment losses on equity securities were recorded during the quarters ended March 31, 2012 and 2011. Management has the intent and ability to hold the investments in equity securities that are at a loss position at March 31, 2012, for a reasonable period of time for a forecasted recovery of fair value up to (or beyond) the cost of these investments.

The unrealized losses associated with “Collateralized mortgage obligations – private label” (“private-label CMO”) are primarily related to securities backed by residential mortgages. In addition to verifying the credit ratings for the private-label CMOs, management analyzed the underlying mortgage loan collateral for these bonds. Various statistics or metrics were reviewed for each private-label CMO, including among others, the weighted average loan-to-value, FICO score, and delinquency and foreclosure rates of the underlying assets in the securities. At March 31, 2012, there were no “sub-prime” securities in the Corporation's private-label CMOs portfolios. For private-label CMOs with unrealized losses at March 31, 2012, credit impairment was assessed using a cash flow model that estimates the cash flows on the underlying mortgages, using the security-specific collateral and transaction structure. The model estimates cash flows from the underlying mortgage loans and distributes those cash flows to various tranches of securities, considering the transaction structure and any subordination and credit enhancements that exist in that structure. The cash flow model incorporates actual cash flows through the current period and then projects the expected cash flows using a number of assumptions, including default rates, loss severity and prepayment rates. Management's assessment also considered tests using more stressful parameters. Based on the assessments, management concluded that the tranches of the private-label CMOs held by the Corporation were not other-than-temporarily impaired at March 31, 2012, thus management expects to recover the amortized cost basis of the securities.

The following table states the name of issuers, and the aggregate amortized cost and fair value of the securities of such issuer (includes available-for-sale and held-to-maturity securities), in which the aggregate amortized cost of such securities exceeds 10% of stockholders' equity. This information excludes securities backed by the full faith and credit of the U.S. Government. Investments in obligations issued by a state of the U.S. and its political subdivisions and agencies, which are payable and secured by the same source of revenue or taxing authority, other than the U.S. Government, are considered securities of a single issuer.

Securities not due on a single contractual maturity date, such as collateralized mortgage obligations, are classified in the period of final contractual maturity. The expected maturities of collateralized mortgage obligations and certain other securities may differ from their contractual maturities because they may be subject to prepayments or may be called by the issuer.

As indicated in Note 5 to these consolidated financial statements, management evaluates investment securities for OTTI declines in fair value on a quarterly basis.

The “Obligations of Puerto Rico, States and political subdivisions” classified as held-to-maturity at March 31, 2012 are primarily associated with securities issued by municipalities of Puerto Rico and are generally not rated by a credit rating agency. The Corporation performs periodic credit quality reviews on these issuers. The decline in fair value at March 31, 2012 was attributable to changes in interest rates and not credit quality, thus no other-than-temporary decline in value was necessary to be recorded in these held-to-maturity securities at March 31, 2012. At March 31, 2012, the Corporation does not have the intent to sell securities held-to-maturity and it is not more likely than not that the Corporation will have to sell these investment securities prior to recovery of their amortized cost basis.
