Caltex Australia Ltd
(ASX:CTX) has posted a 61 per cent dip in net profit to $141.65 million for the first half of the year.
The oil producer says exchange rate volatility and major planned maintenance at both Lytton and Kurnell refineries negatively affected the result.
A three per cent rise in total revenue was recorded, to $9 billion for the six months to 30 June, Caltex attributing the growth to an increase in average crude prices and transport fuel sales volumes.
An interim dividend of 30 cents per share fully franked has been declared.
Caltex reported a profit of $314 million for the year to 30 December 2009.
