Debt Disclosure [Abstract] |
Debt | The Company had outstanding non-recourse secured mortgages and notes payable of $1,043,934 and $1,415,961 as of June 30, 2013 and December 31, 2012, respectively. Interest rates, including imputed rates on mortgages and notes payable, ranged from 3.6% to 8.5% at June 30, 2013 and December 31, 2012 and the mortgages and notes payables mature between 2013 and 2027 as of June 30, 2013. The weighted-average interest rate at June 30, 2013 and December 31, 2012 was 5.4% and 5.6%, respectively. In June 2013, the Company issued $250,000 aggregate principal amount of 4.25% Senior Notes due 2023 (“Senior Notes”) at an issuance price of 99.026% of the principal amount. The Senior Notes are unsecured, pay interest semi-annually in arrears and mature in June 2023. The Company may redeem the notes at its option at any time prior to maturity in whole or in part by paying the principal amount of the notes being redeemed plus a premium. The Company issued these Senior Notes at an initial discount of $2,435 which will be recognized as additional interest expense over the term of the Senior Notes. The Senior Notes are rated Baa2 and BBB- by Moody’s Investors Service, Inc. (“Moody’s”) and Standard & Poor’s Rating Services (“S&P”), respectively. On February 12, 2013, the Company refinanced its $300,000 secured revolving credit facility with a $300,000 unsecured revolving credit facility with KeyBank National Association (“KeyBank”), as agent. The unsecured revolving credit facility matures in February 2017 but can be extended until February 2018 at the Company’s option. The unsecured revolving credit facility bore interest at LIBOR plus 1.50% to 2.05% based on the Company’s leverage ratio, as defined therein. Since the Company has obtained an investment-grade unsecured debt rating from both Moody’s and S&P, the interest rate under the unsecured revolving credit facility ranges from LIBOR plus 0.95% to 1.725% (1.15% as of June 30, 2013) depending on the Company's unsecured debt rating. In addition, the Company increased its availability under the unsecured revolving credit facility from $300,000 to $400,000. At June 30, 2013, the unsecured revolving credit facility had no amounts outstanding, outstanding letters of credit of $7,644 and availability of $392,356, subject to covenant compliance. In connection with the refinancing discussed above, the Company also procured a five-year $250,000 unsecured term loan facility from KeyBank, as agent. The unsecured term loan matures in February 2018, required regular payments of interest only at interest rates ranging from LIBOR plus 1.45% to 2.00% dependent on the Company's leverage ratio, as defined therein and can be prepaid without penalty. Since the Company has obtained an investment-grade unsecured debt rating from both Moody’s and S&P, the interest rate under the unsecured term loan ranges from LIBOR plus 1.10% to 2.10% (1.35% as of June 30, 2013) depending on the Company’s unsecured debt rating. As of June 30, 2013, the Company entered into an interest-rate swap agreement to fix LIBOR at 0.73% through February 2018 on the $64,000 of outstanding LIBOR-based borrowings. During 2012, the Company procured a $255,000 secured term loan from Wells Fargo Bank, National Association (“Wells Fargo”), as agent. The term loan matures in January 2019. The term loan required regular payments of interest only at interest rates ranging from LIBOR plus 2.00% to 2.85% dependent on the Company's leverage ratio, as defined therein. Since the Company has obtained an investment-grade unsecured debt rating from both Moody’s and S&P, the interest rate under the secured term loan ranges from LIBOR plus 1.50% to 2.25% (1.75% as of June 30, 2013) depending on the Company's unsecured debt rating. The Company may prepay any outstanding borrowings under the term loan facility at a premium through January 12, 2016 and at par thereafter. During 2012, the Company entered into interest-rate swap agreements to fix LIBOR at a weighted-average rate of 1.42% through January 2019 on the $255,000 of outstanding LIBOR-based borrowings. The term loan was initially secured by ownership interest pledges by certain subsidiaries that collectively owned a borrowing base of properties. In February 2013, the Company amended the term loan to release the collateral as security. The unsecured revolving credit facility and the unsecured term loans are subject to financial covenants, which the Company was in compliance with at June 30, 2013. The Company had $25,000 and $35,551 secured term loans with KeyBank, which were satisfied in January 2012 and the Company recognized debt satisfaction charges of $1,578 as a result of the satisfaction. During 2010, the Company issued $115,000 aggregate principal amount of 6.00% Convertible Guaranteed Notes due 2030. The notes pay interest semi-annually in arrears and mature in January 2030. The holders of the notes may require the Company to repurchase their notes in January 2017, January 2020 and January 2025 for cash equal to 100% of the notes to be repurchased, plus any accrued and unpaid interest. The Company may not redeem any notes prior to January 2017, except to preserve its REIT status. The notes have a current conversion rate of 146.2412 common shares per one thousand principal amount of the notes, representing a conversion price of approximately $6.84 per common share. The conversion rate is subject to adjustment under certain circumstances, including increases in the Company's dividend rate above a certain threshold and the issuance of stock dividends. The notes are convertible by the holders under certain circumstances for cash, common shares or a combination of cash and common shares at the Company's election. The notes are convertible prior to the close of business on the second business day immediately preceding the stated maturity date, at any time beginning in January 2029 and also upon the occurrence of specified events. During the six months ended June 30, 2013, $42,750 aggregate principal amount of the notes were converted for 6,167,111 common shares and aggregate cash payments of $2,663, plus accrued and unpaid interest resulting in aggregate debt satisfaction charges of $10,633. During 2007, the Company issued an aggregate $450,000 of its 5.45% Exchangeable Guaranteed Notes due 2027. The Company prepaid $387,850 of the notes prior to 2012 and the remaining $62,150 of notes were repurchased by the Company and satisfied in January 2012 pursuant to a holder repurchase option. This resulted in debt satisfaction charges of $44. Below is a summary of additional disclosures related to the 6.00% Convertible Guaranteed Notes due 2030.
