Investments [Abstract] |
Investments | Note 10 – Investments Although the Company currently has the intent and the ability to hold the securities in its investment portfolio to maturity, the securities are all marketable and are classified as “available for sale” to allow maximum flexibility with regard to interest rate risk and liquidity management. Pursuant to FASB’s guidance on accounting for debt and equity securities, available for sale securities are carried on the Company’s financial statements at their estimated fair market values, with monthly tax-effected “mark-to-market” adjustments made vis-à-vis accumulated other comprehensive income in shareholders’ equity. The Company’s available-for-sale investment securities totaled $399 million at March 31, 2013, and $380 million at December 31, 2012. Amortized Cost And Estimated Fair Value The amortized cost and estimated fair value of investment securities available-for-sale are as follows (dollars in thousands, unaudited):
