consideration of changes in existing prices provided by contractual arrangements, but not on
escalations based upon future conditions.
In 2004, Shell amended its Annual Report on Form 20-F/A for the calendar year 2003
financial statements following an agreement with the SEC reached on August 24, 2004, with
respect to the amount of proved reserves. The SEC had charged that 4.47 billion barrels of oil
equivalent (boe), or approximately 23 percent of previously reported proved reserves, did not
meet the standard set by law. Shell also reduced its reserves replacement ratio (RRR) — the rate
at which production was replaced by new oil discoveries. According to the SEC Complaint,
Shell’s overstatement of proved reserves, and its delay in correcting the overstatement, resulted
from (1) its desire to create and maintain the appearance of a strong RRR, a key performance
indicator in the oil and gas industry, (2) the failure of its internal reserves estimation and
reporting guidelines to conform to applicable regulations, and (3) the lack of effective internal
controls over the reserves estimation and reporting process.
Reduction of RRR
In a series of announcements between January 9 and May 24, 2004, Shell
disclosed that it had recategorized 4.47 billion boe, or approximately 23
percent, of the proved reserves it reported as of year-end 2002, because they
were not proved reserves as defined in Commission Rule 4-10 of Regulation S-X. This
recategorization reduced the standard measure of future cash flows by approximately $6.6 billion
as reported in Shell’s original 2002 Form 20-F, Supplemental Information under SFAS 69.
On July 2, 2004, Shell filed an amended 2002 Form 20-F reflecting the restatement of its
proved reserves and standard measure of future cash flows for the years 1999 to 2002 as follows:
