Development/Redevelopment On January 24, 2018, the Company entered into a lease agreement with an affiliate of Leidos Holdings, Inc. for a build-to-suit project with approximately 276,000 net rentable square feet of Class A office space at the Company's 17Fifty Presidents Street development project located in Reston, Virginia. Concurrently with the execution of the lease, the Company commenced development of the project and expects the building to be completed and available for occupancy during the second quarter of 2020. On January 31, 2018, the Company partially placed in-service its Signature at Reston development project comprised of 508 apartment units and retail space aggregating approximately 518,000 square feet located in Reston, Virginia. This project was completed and fully placed in-service on June 7, 2018. On February 23, 2018, the Company entered into a lease agreement with Fannie Mae to lease approximately 850,000 net rentable square feet of Class A office space at the Company's Reston Gateway development project located in Reston, Virginia. The initial phase of the project will consist of two Class A office buildings aggregating approximately 1.1 million net rentable square feet. On August 31, 2018, the Company commenced development of the project. On June 20, 2018, the Company partially placed in-service its Proto Kendall Square development project comprised of 280 apartment units and retail space aggregating approximately 167,000 square feet located in Cambridge, Massachusetts. This project was completed and fully placed in-service on September 1, 2018. On August 7, 2018, the Company entered into an agreement with a third party to (1) share certain pre-development costs during the pre-lease period and (2) to form a joint venture to thereafter own and develop a leasehold interest in 343 Madison Avenue located in New York City, which will support a Class A office tower with approximately 850,000 net rentable square feet. The Company will serve as development manager of the project and will own a 55% interest in the joint venture. In 2016, the Company was selected by the Metropolitan Transportation Authority ("MTA") as the developer of the project and will enter into a pre-lease agreement and a 99-year ground lease with the MTA for the site. There can be no assurances that the transaction will be completed on the terms currently contemplated, or at all. On November 9, 2018, the Company completed and fully placed in-service 191 Spring Street, a Class A office redevelopment project with approximately 171,000 square feet located in Lexington, Massachusetts. On December 1, 2018, a consolidated entity in which the Company has a 95% interest completed and fully placed in-service Salesforce Tower, a Class A office project with approximately 1,421,000 net rentable square feet located in San Francisco, California (See Notes 10 and 19). Ground Lease On November 29, 2018, the Company executed a 65-year ground lease for land totaling approximately 5.6 acres at Platform 16 located in San Jose, California, which will support approximately 1.1 million square feet of commercial office space. The ground lease provides the Company with the right to purchase the land during a 12-month period commencing in the 13th month following the rent commencement date at a purchase price of approximately $134.8 million. The Company made a deposit totaling $15.0 million, which deposit may only be credited against the purchase price of the land. The Company’s option to purchase the land is considered a bargain purchase option and as a result, the Company has concluded that the lease should be accounted for as a capital lease. At the inception of the ground lease only a portion of the land was available for lease from the lessor (See Note 19). As a result, the Company recorded an approximately $12.4 million capital lease asset and liability, which is reflected within Real Estate (Land Held for Future Development) and Other Liabilities on the Company’s Consolidated Balance Sheets, reflecting the portion of the land available for lease from the lessor under the ground lease. Capital lease assets and liabilities are accounted for at the lower of fair market value or the present value of future minimum lease payments. The capital lease is for land only. Therefore, the Company will not depreciate the capital lease asset because land is assumed to have an indefinite life. As of November 29, 2018, future minimum lease payments related to the recognized portion of the capital lease are as follows (in thousands):
Period from November 29, 2018 through December 31, 2018 | $ | 1,385 |
2019 | 427 |
2020 | 11,132 |
Total expected minimum lease payments | 12,944 |
Interest portion | (547 | )
Present value of expected net minimum lease payments | $ | 12,397 |
