Subject : Company Performance for 3rd Quarter 2005 To : President The Stock Exchange of Thailand Rayong Purifier Public Company Limited and its subsidiaries would like to clarify the 25.74 % or 43.65 Million Baht decrease in the Company's Net Profit after Tax in 3rd Quarter 2005 (3Q05) compared to 3rd Quarter2004 (3Q04). The key factors that caused the decrease of Net Profit from 169.61 Million Baht in 3Q04 to 125.96 Million Baht in 3Q05 can be summarized as follows:- 1. Decrease in Gross Profit In 3Q05, the company has 248 Million Baht of Gross Profit, decreased 98 Million Baht or 28% compared to 346 Million Baht in the same period of 2004. The decrease is due to the change of accounting books keeping which result from the acquisition of transportaion company as an affiliated company in 2005. Therefore, the Transportation Cost has to be recorded as Cost of Goods Sold, instead of Selling and Administration Expenditure. Furthermore, the abrogation of the controlled diesel price policy in July 2005 has invited high competition in pricing and caused the marketing margin to decline. Moreover, the world oil price fluctuation during this quarter also hurt the marketing margin. However,the company managed to maximize the gross profit by swithching the production mode to maximize export volume which generated higher margin. 2. Increase of Sale Revenue and Service On the other hand, the rise of world oil price, $72/BBL of Means of Platts Singapore average in 3Q05, which increased $22/BBL or 54% compared to $50/BBL average in 3Q04 cause the rise to the Sales Revenue in 3Q05 to 4,114 Million Baht from 2,599 Million Baht in 3Q04, increased by 1,515 Million Baht or 58%. The total sales consists of 37 Million Liters of export volume, which increased 19 Million Liters or 106% compared to the same period of 2004 3. Decrease of Selling and Administration Expenditure There was 41 Million Baht or 34% decrease in the Selling and Administration Expenditure in 3Q05, from 122 Million Baht in 3Q04 to 81 Million Baht in 3Q05. This is a result of 32 Million Baht of transportation cost changed to be recorded as Cost of Goods Sold, as described in topic 1 above. In additional, the merger with SCT group, from January 2005, also reduces consolidated Selling and Administration Cost. As a result, the companys net profit has decreased by 25.74% or 43.65 Million Baht in 3Q05 compared to 3Q04. Please be so informed.
