Our investment securities consist of certificates of deposit, corporate bonds and federal tax-exempt state and municipal government debt. All investment securities are considered available-for-sale and are “investment grade”, carried at fair value, and there have been no gains or losses on their disposal.

The scheduled maturities of the debt securities are between 2013 and 2040 and are all callable within one year.
