Foreign Exchange VolatilityMore than half of TSMC’s capital expenditures and manufacturing costs are denominated in currencies other than NT dollars, primarily in US dollars, Japanese yen and Euros. In 2014, more than 90% of the Company’s sales were denominated in US dollars and currencies other than NT dollars. Specifically, based on TSMC’s 2014 results, every 1% depreciation of the US dollar against the NT dollar exchange rate may result in approximately 0.4 percentage point decrease in TSMC’s operating margin in NT$. (Why is this?)TSMC utilizes short-term debt denominated in foreign currencies and derivative financial instruments, including currency forward contracts and cross currency swaps, to hedge our currency exposure.
