1	Borrowings are shown as short-term due to our intent to repay within twelve months.The effective interest rate reflects the margin added to LIBOR for LIBOR-based borrowings. We also pay fees for unused borrowing capacity and standby letters of credit.
2	The 10.125% notes due 2015 are classified as long-term debt (not current maturities) as of June 30, 2015 due to our intent and ability to refinance these notes at maturity using our line of credit.
3	As of June 30, 2015, we had initiated prepayment; as such, this debt is classified as current maturities of long-term debt.
4	Non-publicly traded debt.
5	The unamortized deferred gain was realized upon the August 2011 settlement of interest rate swaps as discussed in Note 6.
6	The debt balances as of December 31, 2014 and June 30, 2014 have been adjusted to reflect our early adoption of ASU 2015-03 and related election as disclosed in Note 17.
