(1) Apache guaranteed and is contingently liable for certain debt. Fixed
charges, relating to the debt for which Apache was contingently liable,
have not been included in the fixed charges for any of the periods shown
above.
(2) Represents the portion of rental expense assumed to be attributable to
interest factors of related rental obligations determined at interest
rates appropriate for the period during which the rental obligations were
incurred. Approximately 32 percent to 34 percent applies for all periods
presented.
(3) The $11 million represents the total amount required to cover the
preferred interest requirements of consolidated subsidiaries of $9 million
reported on the Statement of Consolidated Operations. The Company does not
receive a tax benefit for a certain portion of preferred interest.
Consequently, an additional $2 million of pre-tax earnings is required to
cover these fixed charges.
(4) The Company does not receive a tax benefit for its preferred stock
dividends. As a result, this amount represents the pre-tax earnings that
would be required to cover preferred stock dividends of $8 million.
(5) Earnings were inadequate to cover fixed charges and combined fixed charges
and preferred stock dividends by $237 million and $240 million,
respectively, due to the $243 million write-down of the carrying value of
United States oil and gas properties.
