ITEM 5. OTHER EVENTS - ------ ------------ On June 16, 2000, Occidental Petroleum Corporation announced that it is exploring options to sell or otherwise exit several of its chemical intermediate businesses, including its Niagara Falls chemical intermediate facility. These businesses have combined annual sales of approximately $430 million. This process is expected to be completed by the end of the year. This will continue Occidental's program of focusing its chemical division on its core chlor-alkali and vinyls businesses. OxyChem's performance chemicals businesses, including silicates, pool and chrome chemicals, will not be affected by this strategic decision. Proceeds from the asset sales will be applied to Occidental's previously announced debt-reduction program. An after-tax charge of $80 million will be taken in the second quarter as a result of this decision. The after-tax charge reflects costs in connection with the disposition of the Niagara Falls chemical intermediate facility, including, among other things, the write down to realizable value of the assets, employee severance and decommissioning.
