The shock of these announcements probably moved companies toward
greater conservatism in their use of derivatives. Additionally, the surprise
losses strengthened the hand of those calling for fuller disclosure. SFAS 133
(“Accounting for Derivative and Similar Instruments and Hedging Activities”)
now requires all derivatives to be recorded as either assets or liabilities
at fair value. As the values change, the resulting gains or losses may be recognized
immediately or deferred, depending on whether the derivative qualifies
for classification as a hedge.
