OxyChem's Evaluated Receipt Settlement (ERS) program eliminates paperwork and simplifies the billing
and payment process.

• With ERS, our customers no longer receive invoices. Payments are made for quantities shipped
  and received in the customer's receiving process – at a prearranged contract price.
• Payments can be submitted electronically through the banking industry's Automated Clearing
  House (ACH) and automatically applied to your OxyChem account.
• ERS significantly reduces billing and payment discrepancies.
