When China Noah replaces the Chinese wood supplier with Indonesian supplier, the prices of CNY 62.6/m2 came with the rough estimation of 8% cheaper than the current Chinese prices. China Noah started traded with Indonesian company in 2010 with the evaluation of 30% Indonesian sourcing of the total 17.2 million square meters of flooring. The price which was quoted for wood per square meter is IDR 84,090 i.e. 62.6 in Chinese yuan per square meter. Return on sales for 2010 a) If the exchange rate is to be change as per the forecast i.e. 1 CNY = IDR, the return on sales is figured at 14.9% b) If China Noah were to use the currency forward, the 2010 forward rate is IDR 1450 = 1 CNY, where return on sales is 14.6%. c) If the change in exchange rate remains constant, IDR 1344 = 1 CNY, the forecast return on sales to be figured at 13.5% These return on sales forecast with the change in the exchange rate of IDR and CNY helps the company to secure the normal profit within the time frame mentioned.
