FAIR VALUES – NONRECURRING

As a result of the sharp decline of the forward price curve during 2015, as well as the decision to sell or exit non-core operations. Occidental recognized approximately $6.5 billion in pre-tax impairment charges related to proved oil and gas properties. Internationally, Occidental recognized $4.7 billion in pre-tax impairment charges related to $1.8 billion in charges in Oman, $1.3 billion in Iraq and Libya, $1 billion in Qatar, and $550 million in Colombia and Bolivia.  Domestically, Occidental recognized approximately $763 million pre-tax impairment charges related to the sale of the Williston assets, $460 million pre-tax impairment charges for assets in the Piceance Basin as well as a $554 million pre-tax impairment charges related to proved oil and gas properties in South Texas.

The impairment tests, including the fair value estimation, incorporated a number of assumptions involving expectations of future cash flows.  These assumptions included estimates of future product prices, which Occidental based on forward price curves and, where applicable, contractual prices, estimates of oil and gas reserves, estimates of future expected operating and development costs and a risk adjusted discount rate of 8-20 percent.  These properties were impacted by persistently worldwide low oil and natural gas prices and changing management’s development plans.  Occidental used the income approach to measure the fair value of these properties, using inputs categorized as Level 3 in the fair value hierarchy.

In the fourth quarter 2015, Occidental recognized approximately $814 million in pre-tax impairment charges for a Midstream CO2 treatment plant related to recurring CO2 shortfalls and unpaid penalty fees.

In 2015, Occidental recognized approximately $121 million pre-tax charges related to the impairments of Chemical assets.
