Caltex Australia : Refiner Margin Update (September 2016)

27 October 2016

Caltex advises its realised lagged1Caltex Refiner Margin (CRM2), in respect of CRM sales from production for the month of September 2016.

The September unlagged CRM was US$ 10.82/bbl. This is above the prior month (August 2016: US$ 8.77/bbl) but below the prior year monthly comparative (US$ 18.05/bbl).

Regionally, the unlagged Caltex Singapore Weighted Average Margin was US$ 10.02/bbl, above the prior month (August 2016: US$ 8.42/bbl) but below the prior year (August 2015: US$ 14.48/bbl).

Lower Brent crude oil prices and higher petrol and diesel refiner margins in the last week of September drove a favourable US$ 0.12/bbl pricing lag (August unfavourable pricing lag: US($0.69)/bbl).

The September 2016 realised CRM was US$ 10.94/bbl, above August 2016 CRM of US$ 8.08/bbl but below the prior year comparative (September 2015: US$ 17.28/bbl).

Sales from production in September 2016 of 532ML were below the prior month (August 2016: 580ML), but above the prior year comparative (September 2015: 514ML).

For the nine months from 1 January 2016 to 30 September 2016, the average realised CRM was US$ 9.94/bbl (2015: US$ 16.81/bbl) with CRM sales from production totalling 4,616 ML (2015: 3,867 ML).

1. A fall in the Australian dollar crude price, particularly at the latter end of the month, produces a positive lag effect on the CRM (i.e. increases the CRM) and, conversely, in the event of a rise in the Australian dollar crude price, a negative lag effect occurs (i.e. reduces the CRM).

2. CRM represents the difference between the cost of importing a standard Caltex basket of products to eastern Australia and the cost of importing the crude oil required to make that product basket.

   The CRM is calculated in the following manner:

   Weighted Singapore product prices (for a standard Caltex basket of products)

   Less: Reference crude price (the Caltex reference crude marker is Dated Brent) Equals: Singapore Weighted Average Margin (Dated Brent basis)

   Plus: Product quality premium Crude discount

   Product freight Less: Crude premium

   Crude freight Yield Loss

   Equals: Caltex Refiner Margin

   The Caltex Refiner Margin is converted to an Australian dollar basis using the prevailing average monthly exchange rate.

   CRM is just one contributor to the replacement cost of sales operating profit (RCOP) EBIT earnings (excluding significant items). Other items contributing to the RCOP EBIT include Transport Fuels volume and margin, Lubricants and Specialties volume and margin, Non-Fuel Income and Other Margin less Operating Expenses.

3. The replacement cost of sales operating profit (RCOP) excludes the impact of the fall or rise in oil and product prices (a key external factor) and presents a clearer picture of the company's underlying business performance. It is calculated by restating the cost of sales using the replacement cost of goods sold rather than the historic cost, including the effect of contract based revenue lags.
