b. Investment securities available for sale: Available-for-sale securities are defined as securities other than the ones classified as “held-to-maturity securities”, “trading securities” and “originated loans”.
Available-for-sale investment securities are subsequently remeasured at fair value. When the prices cannot be determined reliably, securities are carried at the amortised cost using the effective yield method. Unrealized gains and losses arising from changes in the fair value of securities classified as available-for-sale are recognized in the shareholders’ equity as “Marketable securities value increase fund”, unless there is a permanent decline in the fair values of such assets or they are disposed. When these securities are disposed or impaired, the related fair value differences accumulated in the shareholders’ equity are transferred to the income statement.
