Our exposure to market risk results primarily from fluctuations in interest rates on our borrowings and our interest rate swap agreements, and price increases in diesel fuel. Except as described in Note 8—Derivatives and Note 9—Long-Term Debt in Part I, Item 1 of this Quarterly Report on Form 10-Q, which are incorporated herein, there have been no other material changes to our exposure to market risks from those disclosed in our Annual Report.
