Debt Instruments [Abstract]
DEBT	DEBT In connection with the acquisition of San Antonio Center in January 2015, we assumed a mortgage loan with a face amount of $18.7 million and a fair value of $19.3 million. The mortgage loan bears interest at 5.27% and matures on January 1, 2016. On March 16, 2015, we issued $200.0 million aggregate principal amount of 4.50% senior unsecured notes due December 1, 2044. The notes were offered at 105.38% of the principal amount with a yield to maturity of 4.18%.

Our net proceeds from the March note offering after issuance premium, underwriting fees and other costs were $208.6 million.

At June 30, 2015, the outstanding balance was $106.5 million. Our revolving credit facility, term loan and certain notes require us to comply with various financial covenants, including the maintenance of minimum shareholders’ equity and debt coverage ratios and a maximum ratio of debt to net worth.
