Schedule of Annual Maturities of Long-Term Debt

The following schedule of annual maturities of the principal amount of total debt assumes we use available capacity under our revolving credit agreement to refinance unsecured floating rate term loans and fixed rate notes due in 2016 through 2018. Based on this refinancing assumption, all of the obligations other than the VIE unsecured floating rate term loan due prior to 2019 are reflected as maturities for 2019 and beyond.
