[1] This debt is comprised of separate non-cross-collateralized loans each secured by a mortgage of a different hotel.

[2] We originally issued $636 million (face amount) of these notes. After redemptions in 2011 and 2012, $234 million (face amount) of these notes were outstanding at March 31, 2013. These notes were initially sold at a discount that provided an effective yield of 12.875% before transaction costs.

[3] This loan is related to our Knickerbocker development project and is fully secured by restricted cash and a mortgage. Because we were able to assume an existing loan when we purchased this hotel, we were not required to pay any local mortgage recording tax. This loan, which allows us to borrow up to $85 million, can be extended for one year subject to satisfying certain conditions.
