Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Accounting | Occidental has made its disclosures in accordance with United States generally accepted accounting principles (GAAP) as they apply to interim reporting, and condensed or omitted, as permitted by the Securities and Exchange Commission’s (SEC) rules and regulations, certain information and disclosures normally included in consolidated financial statements and the notes.
Accounting and Disclosure Changes | Accounting and Disclosure Changes In January 2019, Occidental adopted the new lease standard Topic 842 - Leases (ASC 842). The new standard requires Occidental to recognize most leases, including operating leases, on the consolidated condensed balance sheet. The new rules require lessees to recognize a right-of-use asset (ROU) and lease liability for all leases with lease terms of more than 12 months. Occidental adopted the standard using the modified retrospective approach, including adopting several optional practical expedients. Occidental has developed and implemented an internal software solution to support the identification, documentation, tracking, accounting and supplemental reporting of leases under ASC 842. Continued enhancements to the software solution through 2019 are expected to ensure manual processes are streamlined while maintaining control functionality surrounding completeness in population and reporting. See Note 13, Leases.
