Debt

On January 5, 2018, we completed a $100,000,000 refinancing of 33-00 Northern Boulevard (Center Building), a 471,000 square foot office building in Long Island City, New York. The seven-year loan is at LIBOR plus 1.80%, which was swapped to a fixed rate of 4.14%. We realized net proceeds of approximately $37,200,000 after repayment of the existing 4.43% $59,800,000 mortgage and closing costs.
