statement in the first paragraph, if correct, to indicate that
there
were no material weaknesses identified in the course of such
review
and evaluation. Additionally, explain to us what you mean by your

why you have classified your unrealized gains and losses on
derivatives as a component of "Other Income(Expense)" as opposed
to a
