MORTGAGES PAYABLE

On June 1, 2017, we completed a $500,000,000 refinancing of the office portion of 731 Lexington Avenue. The interest-only loan is at LIBOR plus 0.90% and matures in June 2020, with four one-year extension options. In connection therewith, we purchased an interest rate cap with a notional amount of $500,000,000 that caps LIBOR at a rate of 6.0%. The property was previously encumbered by a $300,000,000 interest-only mortgage at LIBOR plus 0.95% which was scheduled to mature in March 2021.

The following is a summary of our outstanding mortgages payable. We may refinance our maturing debt as it comes due or choose to repay it.
