[1] We expect to refinance the current maturities of our debt obligations at or prior to their maturity. Long-term and current maturities of debt reflect the classification of such obligations at March 31, 2015, after taking into consideration the long-term refinancing of Senior Notes X and Commercial Paper Notes using proceeds from our senior notes offering in May 2015 (see Note 17).
