(A)

The interest rates reflected above for the senior notes represent the range of the coupon rate of the notes outstanding. All other interest rates presented are a weighted average of the outstanding debt. Interest rate on variable-rate debt was calculated using the base rate and spreads in effect at December 31, 2016 and 2015.

(B)	Effective interest rate ranged from 3.5% to 8.1% at December 31, 2016.

Senior Notes

The Company’s various fixed-rate senior notes have interest coupon rates that averaged 4.9% and 5.2% at December 31, 2016 and 2015, respectively. Senior notes with an aggregate principal amount of $82.2 million may not be redeemed by the Company prior to maturity and will not be subject to any sinking fund requirements. The remaining senior notes may be redeemed based upon a yield maintenance calculation.

The fixed-rate senior notes were issued pursuant to indentures that contain certain covenants, including limitation on incurrence of debt, maintenance of unencumbered real estate assets and debt service coverage. The covenants also require that the cumulative dividends declared or paid from December 31, 1993, through the end of the current period cannot exceed Funds From Operations (as defined in the agreement) plus an additional $20.0 million for the same period unless required to maintain REIT status. Interest is paid semiannually in arrears. At December 31, 2016 and 2015, the Company was in compliance with all of the financial and other covenants under the indentures.

Total fees, excluding underwriting discounts, incurred by the Company for the issuance of senior notes were $2.0 million in 2015.

Senior Convertible Notes

In November 2015, the Company elected to redeem its senior convertible notes ($350.0 million aggregate principal amount outstanding at maturity), in their entirety, prior to maturity. The conversion price consisted of cash equal to the principal amount of the senior convertible notes and a premium paid in the Company’s common shares (equal to 9.0311 common shares per $1,000 principal amount of the senior convertible notes). The Company issued 3.2 million shares upon conversion of the convertible notes.

Unsecured Term Loan

The Company maintains a $400 million unsecured term loan with Wells Fargo Bank, National Association, as administrative agent, and PNC Bank, National Association, as syndication agent (the “Unsecured Term Loan”). The Unsecured Term Loan has a maturity date of April 2017, with three one-year borrower options to extend upon the Company’s request, provided certain conditions are satisfied. The Company may increase the amount of the facility provided that lenders agree to certain terms. The outstanding principal amount under this credit facility may not exceed $600 million. The Unsecured Term Loan bears interest at variable rates based on LIBOR as defined in the loan agreements plus a specified spread based on the Company’s long-term senior unsecured debt rating (1.1% at December 31, 2016). The Company is required to comply with covenants similar to those contained in the Revolving Credit Facilities. The Company was in compliance with these financial covenants at December 31, 2016 and 2015.

Secured Term Loan

The Company maintains a collateralized term loan (the “Secured Term Loan”) with a syndicate of financial institutions, for which KeyBank National Association serves as the administrative agent. The Secured Term Loan matures in April 2017, which may be extended for one year to April 2018 at the Company’s option. Borrowings under the Secured Term Loan bear interest at variable rates based on LIBOR, as defined in the loan agreement, plus a specified spread (1.35% at December 31, 2016) based on the Company’s long-term senior unsecured debt rating. The collateral for the Secured Term Loan is real estate assets, or investment interests in certain assets, that are already encumbered by first mortgage loans. The Company is required to comply with covenants similar to those contained in the Revolving Credit Facilities. The Company was in compliance with these financial covenants at December 31, 2016 and 2015.
