On June 28, 2011, the Company notified Branch Banking and Trust Company that it was exercising its right to early terminate the Credit Agreement which was scheduled to mature on September 19, 2012. The termination was effective on July 1, 2011. The Company did not incur any prepayment penalties in connection with the early termination of the Credit Agreement.

Community Development District ("CDD") bonds financed the construction of infrastructure improvements at several of the Company's projects. The principal and interest payments on the bonds are paid by assessments on, or from sales proceeds of, the properties benefited by the improvements financed by the bonds. The Company has recorded a liability for CDD debt that is associated with platted property, which is the point at which the assessments become fixed or determinable. Additionally, the Company has recorded a liability for the balance of the CDD debt that is associated with unplatted property if it is probable and reasonably estimable that the Company will ultimately be responsible for repaying either as the property is sold by the Company or when assessed to the Company by the CDD. Accordingly, the Company has recorded debt of $30.2 million and $29.4 million related to CDD debt as of December 31, 2011 and December 31, 2010, respectively. Total outstanding CDD debt was $56.8 million at December 31, 2011 and $57.7 million at December 31, 2010.

In connection with the sale of the Company's office building portfolio in 2007, the Company has approximately $29.3 million of defeased debt. The Company purchased treasury securities sufficient to satisfy the scheduled interest and principal payments contractually due under the mortgage debt agreement. These securities were placed into a collateral account for the sole purpose of funding the principal and interest payments as they become due. The indebtedness remains on the Company's Consolidated Balance Sheets at December 31, 2011 and 2010 since the transaction was not considered to be an extinguishment of debt.
