[1] In October 2016, we entered into a $725 million CMBS loan secured by the Hilton San Francisco Union Square and the Parc 55 Hotel San Francisco (“SF CMBS Loan”) and a $1.275 billion CMBS loan secured by the Hilton Hawaiian Village Waikiki Beach Resort (“HHV CMBS Loan”).

[2] Assumes the exercise of all extensions that are exercisable solely at our option. The mortgage loan for Hilton Denver City Center matures in 2042 but is callable by the lender beginning August 2022. 

[3] We are actively negotiating a one-year maturity date extension for the $12 million loan secured by the Doubletree Spokane to October 2021. The loan was not paid in full at its originally scheduled maturity date in October 2020 due to current market conditions. Failure to pay off the loan constitutes an event of default; however, we have not received, nor do we expect to receive, notice of the lenders’ intent to foreclose.

[4] In September 2020, the 2016 Term Loan was fully repaid

[5] In May 2020, we amended our credit and term loan facilities which added a LIBOR floor of 25 basis points.

[6] In September 2020, we increased our aggregate commitments under the Revolver by $75 million to $1.075 billion and extended the maturity date with respect to $901 million of the aggregate commitments for two years to December 2023, including all $75 million of the increased Revolver commitments. The maturity date for the remaining $174 million of commitments under the Revolver is December 2021.
