[1] Excludes our term loan facilities of $620.0 million, unsecured senior notes of $592.7 million, exchangeable senior notes of $563,000, unsecured notes payable of $1.7 million, a letter of credit on a mortgage loan of $14.8 million, and net premiums on the remaining loans of $69,000. [2] The aggregate cost of these assets for Federal income tax purposes was approximately $3.3 billion at December 31, 2013. [3] As discussed in Note 3 to our Consolidated Financial Statements, we recognized impairment losses of $5.9 million in connection with two properties in the Greater Baltimore region that we determined no longer met our strategic investment criteria. [4] The estimated lives over which depreciation is recognized follow: Building and land improvements: 10-40 years; and tenant improvements: related lease terms. [5] Refer to the paragraphs below for further disclosure. [6] As discussed below, we have the ability to borrow an aggregate of an additional $180.0 million under these term loan facilities, provided that there is no default under the facilities and subject to the approval of the lenders. [7] 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 $69,000 at December 31, 2013 and $1.3 million at December 31, 2012. [8] Includes $13.9 million balance on construction loans with maximum available borrowings of $26.2 million. [9] Under construction or redevelopment at December 31, 2013. [10] Held or under pre-construction at December 31, 2013.
