the reserves, Occidental refers to currently available information, including
relevant past experience, available technology, regulations in effect, the
timing of remediation and cost-sharing arrangements. The environmental reserves
are based on management's estimate of the most likely cost to be incurred and
are reviewed periodically and adjusted as additional or new information becomes
available. For the years ended December 31, 2002 and 2001, Occidental has not
accrued any reimbursements or recoveries as assets. Recoveries and
reimbursements are recorded in income when receipt is probable. Environmental
reserves are recorded on a discounted basis only when a reserve is initially
established and the aggregate amount of the estimated costs for a specific site
and the timing of cash payments are reliably determinable. The reserve
methodology for a specific site is not modified once it has been established.
At sites involving multiple parties, Occidental provides environmental
reserves based upon its expected share of liability. When other parties are
jointly liable, the financial viability of the parties, the degree of their
commitment to participate and the consequences to Occidental of their failure to
participate are evaluated when estimating the company's ultimate share of
liability. Occidental believes that it will not be required to assume a share of
liability of other potentially responsible parties with whom it is alleged to be
jointly liable in an amount that would have a material effect on Occidental's
consolidated financial position or liquidity or results of operations.

Most cost sharing arrangements with other parties fall into one of the
following three categories:
Category 1: Comprehensive Environmental Response, Compensation and
Liability Act (CERCLA) or state-equivalent sites wherein Occidental and other
alleged potentially responsible parties share the cost of remediation in
accordance with negotiated or prescribed allocations;
Category 2: Oil and gas joint ventures wherein each joint venture partner
pays its proportionate share of remedial cost; and
Category 3: Contractual arrangements typically relating to purchases and
sales of property wherein the parties to the transaction agree to methods of
allocating the costs of environmental remediation.
In all three of these categories, Occidental records as a reserve its
expected net cost of remedial activities, as adjusted by recognition for any
non-performing parties.
In addition to the costs of investigating and implementing remedial
measures, which often take in excess of ten years at CERCLA sites, Occidental's
reserves include management's estimates of the cost of operation and maintenance
of remedial systems. To the extent that the remedial systems are modified over
time in response to significant changes in site-specific data, laws,
regulations, technologies or engineering estimates, Occidental reviews and
changes the reserves accordingly on a site-specific basis.
