through 1990 average price = 1.00 12 Investor Relations Supplemental Schedules [OXY LOGO] CHLORINE - -------- OXYCHEM COMMENTARY - ------------------ o Seasonal demand was hindered by milder and wetter weather. This negatively impacted the bleach, water treatment and titanium dioxide market segments. o Pricing declined slightly in the 3rd quarter due to a slowdown in seasonal demand, increased global competition experienced by our customers, and a decline in industry operating rates. o Chlorine industry operating rates declined approximately 2% to 90% in the 3rd quarter versus 2nd quarter 2003. INFLUENCING FACTORS: - -------------------- Industry operating rates are not expected to improve in the 4th quarter. CAUSTIC - ------- OXYCHEM COMMENTARY - ------------------ o Demand for caustic soda declined marginally in the 3rd quarter due to reduced volume into the pulp and paper and refining markets. Caustic soda demand is expected to ease further throughout the 4th quarter due to seasonality. o The price increase of $50 per ton announced for July 1st was unsuccessful. Strong competitive activity and the influence of significant increases in imported caustic brought pricing under pressure and adversely impacted the implementation of the price increase. INFLUENCING FACTORS: - -------------------- The supply/demand balance for caustic soda remains fragile. Industry capacity rationalization and improvement in the U.S. manufacturing sector would provide support for future price improvement. However, elevated chlorine operating rates and increased imports could negatively impact future caustic price increases during periods of weak demand. EDC - --- OXYCHEM COMMENTARY - ------------------ o EDC values remained flat in the 3rd quarter in spite of improved VCM and PVC demand in the Far East. 13 Investor Relations Supplemental Schedules [OXY LOGO] o Unplanned and extended VCM outages in the US and Asia have weakened the EDC supply/demand balance. This is expected to continue throughout the 4th quarter. INFLUENCING FACTORS: - -------------------- PVC production in China via the calcium carbide process has negatively impacted EDC demand and diluted some of the anticipated growth in 2003. PVC/VCM - ------- OXYCHEM COMMENTARY - ------------------ o Reduced 2nd quarter customer inventories and favorable weather led to an improvement in 3rd quarter PVC sales demand. Inventories are at moderate levels going into the 4th quarter. o VCM outages in the U.S. and Asia allowed for price increases at the end of the 3rd quarter and will support price stability in the 4th quarter. o Capacities still exclude the former Borden Geismar and Addis facilities, which remain idle. There is little indication that either plant will restart in 2004. o July PVC pricing was down $.01/lb with August holding steady. The September increase of $.02/lb has been supported in the marketplace. o Demand and pricing for PVC exports improved slightly in the 3rd quarter due mostly to outages in Asia. 3rd quarter pricing ended at $650/MT. o The VCM market is tight with Pemex and Dow currently in an outage and PHH Lake Charles resuming production following their outage. OxyVinyls should benefit with increased 4th quarter sales. INFLUENCING FACTORS: - -------------------- Increased demand in both the domestic and export markets led to improved 3rd quarter margins. 4th quarter margins will be dependant on continued demand and raw material balances. 14 Investor Relations Supplemental Schedules [OXY LOGO] SUMMARY OF OPERATING STATISTICS ------------------------------- THIRD QUARTER NINE MONTHS --------------------- --------------------- CAPITAL EXPENDITURES ($MM) 2003 2002 2003 2002 -------- -------- -------- -------- Oil & Gas California $ 58 $ 57 $ 155 $ 178 Permian 72 50 187 153 Other - U.S. 11 20 37 64 Latin America 30 26 67 77 Middle East and Other 157 92 390 270 Eastern Hemisphere Chemicals 27 21 300 1 56 Corporate 5 17 15 42 -------- -------- -------- -------- TOTAL $ 360 $ 283 $ 1,151 $ 840 ======== ======== ======== ======== 1 Includes $180 for buyout of VCM plant lease and $44 for buyout of railcar leases THIRD QUARTER NINE MONTHS DEPRECIATION, DEPLETION & --------------------- --------------------- AMORTIZATION OF ASSETS ($MM) 2003 2002 2003 2002 -------- -------- -------- -------- Oil & Gas Domestic $ 158 $ 138 $ 481 $ 434 Latin America 15 9 42 27 Middle East and Other 61 52 183 153 Eastern Hemisphere Chemicals 57 44 149 139 Corporate 4 2 11 6 -------- -------- -------- -------- TOTAL $ 295 $ 245 $ 866 $ 759 ======== ======== ======== ======== 15 Investor Relations Supplemental Schedules [OXY LOGO] OCCIDENTAL PETROLEUM CORPORATE ($ millions) 30-SEP-03 31-DEC-02 ------------- ------------- CAPITALIZATION Oxy Long-Term Debt (including current maturities) $ 4,079 $ 4,203 Trust Preferred Securities 454 455 Subsidiary Preferred Stock 75 75 Others 25 26 ------------- ------------- TOTAL DEBT $ 4,633 $ 4,759 ============= ============= EQUITY $ 7,495 $ 6,318 ============= ============= Total Debt To Total Capitalization 38% 43% ============= ============= 16 Investor Relations Supplemental Schedules [OXY LOGO] Statements in this presentation that contain words such as "will" or "expect", or otherwise relate to the future, are forward-looking and involve risks and uncertainties that could significantly affect expected results.
