[1] Excludes our term loan facilities of $770.0 million, senior exchangeable notes of $230.9 million, unsecured notes payable of $1.8 million, and net premiums on the remaining loans of $1.3 million. [2] The aggregate cost of these assets for Federal income tax purposes was approximately $3.4 billion at December 31, 2012. [3] impairment losses of $46.1 million in connection with our property in Greater Philadelphia, Pennsylvania and $19.0 million, including exit costs, in connection with certain properties included in our Strategic Reallocation Plan [4] The estimated lives over which depreciation is recognized follow: Building and land improvements: 10-40 years; and tenant improvements: related lease terms. [5] Several of the fixed rate mortgages carry interest rates that were above or below market rates upon assumption and therefore were recorded at their fair value based on applicable effective interest rates. The carrying values of these loans reflect net unamortized premiums totaling $1.3 million at December 31, 2012 and $2.4 million at December 31, 2011.
