Interest Rate FluctuationTSMC’s exposure to interest rate risks derives primarily from short-term borrowing and long-term debt obligations incurred in the normal course of business. In order to limit its exposure to interest rate risks, TSMC finances its funding needs primarily through internal generation of cash and the issuance of long-term, fixed-rate debt. On the asset side, TSMC places its cash on hand mainly in very short time deposits. Furthermore, the primary objective of TSMC’s cash investments in fixed income securities is to preserve principal in highly liquid markets.In order to maintain the Company’s liquidity profile, the majority of fixed income securities are at the short end of the yield curve.
