Boston Properties, Inc. (NYSE: BXP), a real estate investment trust, announced today that its consolidated joint venture entity in which it has a 60% interest and that owns 767 Fifth Avenue (the General Motors Building) located in New York City, completed the refinancing of approximately $1.6 billion of indebtedness that had been secured by direct and indirect interests in 767 Fifth Avenue. The new mortgage financing has a principal amount of $2.3 billion, bears interest at a fixed interest rate of 3.43% per annum and matures on June 9, 2027. The loan requires interest-only payments during the 10-year term of the loan, with the entire principal amount being due at maturity.

In contemplation of the refinancing, on April 24, 2017, the consolidated joint venture entity terminated forward-starting interest rate swap contracts with notional amounts aggregating $450.0 million and paid approximately $14.4 million, which amount will increase the Company's interest expense over the ten-year term of the financing, resulting in an effective GAAP interest rate of approximately 3.64% per annum (including the amortization of financing costs and additional mortgage recording tax).

After extinguishing the existing indebtedness on the property, the Company intends to use a portion of its share of the net proceeds to repay the $310.0 million of borrowings outstanding under its $1.5 billion unsecured line of credit and for other working capital purposes. The extinguished debt bore interest at a weighted-average rate of approximately 5.96% per annum, an effective GAAP interest rate of approximately 3.03% per annum and was scheduled to mature on October 7, 2017. There was no prepayment penalty associated with the repayment of the prior indebtedness on the property.
