On July 10, 2017, the Company acquired an additional 0.2% interest in the unconsolidated joint venture that owns Colorado Center located in Santa Monica, California for approximately $2.1 million in cash. Following the acquisition, the Company owns a 50% interest in the joint venture. The Company continues to account for the joint venture under the equity method of accounting as there were no changes to the rights of the members as a result of the acquisition. On July 28, 2017, the unconsolidated joint venture obtained mortgage financing collateralized by the property totaling $550.0 million. The mortgage financing bears interest at a fixed rate of 3.56% per annum and matures on August 9, 2027. The loan requires interest-only payments during the 10-year term of the loan, with the entire principal amount due at maturity. The joint venture distributed to the partners the net proceeds from the financing totaling $502.0 million, of which the Company’s share was $251.0 million. Colorado Center is a six-building office complex that sits on a 15-acre site and contains an aggregate of approximately 1,118,000 net rentable square feet with an underground parking garage for 3,100 vehicles. On August 7, 2017, the Company entered into a joint venture with The Bernstein Companies to develop an approximately 733,000 net rentable square foot (subject to adjustment based on finalized building design) build-to-suit Class A office building and below-grade parking garage at 7750 Wisconsin Avenue in Bethesda, Maryland. The joint venture entered into a lease agreement with an affiliate of Marriott International, Inc. under which Marriott will lease 100% of the office building and garage for a term of 20 years, and the building will serve as Marriott’s new worldwide headquarters. Marriott has agreed to fund 100% of the related tenant improvement costs and leasing commissions for the office building. The Company will serve as co-development manager for the venture and expects to commence construction in 2018. The Company and The Bernstein Companies each own a 50% interest in the joint venture. For its initial contribution, The Bernstein Companies contributed land with an initial fair value of $72.0 million and cash and improvements aggregating approximately $4.9 million. The Company contributed cash and improvements aggregating approximately $20.8 million for its initial contribution, of which $11.0 million was distributed to The Bernstein Companies. In addition, the Company was required to fund $25.0 million into an escrow account to be used by the joint venture to fund future development costs. See also Note 10. On September 6, 2017, a joint venture in which the Company has a 50% interest obtained construction financing with a total commitment of $204.6 million collateralized by its Hub on Causeway development project. The construction financing bears interest at a variable rate equal to LIBOR plus 2.25% per annum and matures on September 6, 2021, with two, one-year extension options, subject to certain conditions. The Hub on Causeway is an approximately 385,000 net rentable square foot project containing retail and office space located in Boston, Massachusetts. In connection with the construction financing, the Company obtained the right to complete the construction of the garage underneath the project being developed by an affiliate of its joint venture partner and obtain funding from the garage construction lender. The Company agreed to guarantee completion of the garage to the construction lender and an affiliate of its partner agreed to reimburse the Company for the partner’s share of any payments made under the guarantee. On December 1, 2017, a joint venture in which the Company has a 50% interest commenced construction of a residential project aggregating approximately 320,000 square feet comprised of 440 residential units at its Hub on Causeway mixed-use development project located in Boston, Massachusetts.
