(Note 1) Valuation method of financial instruments and matters related to securities and derivative transactions. Assets (1) Cash and cash equivalents, and (2) Notes and accounts receivable As all of these are settled within a short span of time, the fair value is virtually identical to the carrying value. Therefore, the carrying value is used. (3) Securities and investment securities In the case of the fair value of securities and investment securities, shares are stated at the exchange-listed price and securities are stated at the exchangelisted price or the price quoted by the correspondent financial institution. In the case of those available-for-sale securities which are settled within a short span of time, the fair value is virtually identical to the carrying value. Therefore, the carrying value is used. Liabilities (1) Notes and accounts payable, and (2) Short-term bank loans As all of these are settled within a short span of time, the fair value is virtually identical to the carrying value. Therefore, the carrying value is used. (3) Long-term debt The fair value of long-term debt is calculated as the present value by discounting the total principal and interest on the borrowings by the interest rate which would be assumed if new, similar borrowings were made.
