[1] Net income (loss) from continuing operations represents loss before discontinued operations.

[2] The Bank of America Portfolio net loss includes interest expense of $2,849 and $7,092 for the three and six months ended June 30, 2013 from a defeased mortgage acquired as part of the Joint Venture’s acquisition. The pool of treasury securities pledged as collateral for the mortgage loan generate sufficient cash flows to cover the debt service requirements, but do not generate income to offset the interest expense. The defeased mortgage and corresponding pool of pledged treasury securities were sold in May 2013 for a loss of $4,535.
