[1] Our $225 million line of credit can be extended for one year (to 2015), subject to satisfying certain conditions.

[2] These notes have $492 million in aggregate principal outstanding ($144 million and $96,000 in aggregate principal amount was redeemed in June 2011 and January 2012, respectively) and 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. When that loan is transferred to a new lender and made part of our construction loan, we expect to only pay such tax to the extent of the incremental principal amount of the construction loan.

[4] This loan can be extended for six months, subject to satisfying certain conditions.
