an annual basis or more
frequently if indicators
of impairment arise. In
testing for impairment,
we estimate the fair
value of each operating
segment of our business
and compare the fair
values with the carrying

of an operating segment
is greater than its
carrying value, no
impairment results. We
measure impairment loss
as the amount by which
the carrying amount of
the asset or operating
segment exceeds its fair
value.
