As a result of the Company's net loss in 1998, Anadarko's earnings did not
cover fixed charges by $90 million and did not cover combined fixed charges
and preferred stock dividends by $101 million.
These ratios were computed by dividing earnings by either fixed charges or
combined fixed charges and preferred stock dividends. For this purpose,
earnings include income before income taxes and fixed charges. Fixed
charges include interest and amortization of debt expenses and the
estimated interest component of rentals. Preferred stock dividends are
adjusted to reflect the amount of pretax earnings required for payment.
