Note 3 - Securities
 
Securities are classified into held-to-maturity and available-for-sale categories.  Held-to-maturity (HTM) securities are those that CTBI has the positive intent and ability to hold to maturity and are reported at amortized cost.  Available-for-sale (AFS) securities are those that CTBI may decide to sell if needed for liquidity, asset-liability management or other reasons.  Available-for-sale securities are reported at fair value, with unrealized gains or losses included as a separate component of equity, net of tax.

The amortized cost and fair value of securities at March 31, 2012 are summarized as follows:

There were no pre-tax gains or losses as of March 31, 2012 or 2011.

The amortized cost of securities pledged as collateral, to secure public deposits and for other purposes, was $188.2 million at March 31, 2012 and $198.6 million at December 31, 2011.

The amortized cost of securities sold under agreements to repurchase amounted to $239.7 million at March 31, 2012 and $217.2 million at December 31, 2011.
 
Certain investments in debt and marketable equity securities are reported in the financial statements at amounts less than their historical costs.  CTBI evaluates its investment portfolio on a quarterly basis for impairment.  The analysis performed as of March 31, 2012 indicates that all impairment is considered temporary, market driven, and not credit-related. The percentage of total investments with unrealized losses as of March 31, 2012 was 20.2% compared to 4.8% as of December 31, 2011.  The following tables provide the amortized cost, gross unrealized losses, and fair market value, aggregated by investment category and length of time the individual securities have been in a continuous unrealized loss position as of March 31, 2012 that are not deemed to be other-than-temporarily impaired.
