JBG Legacy Funds, other third parties and the WHI Impact Pool. Substantially all our assets are held by, and our operations are conducted through, JBG SMITH LP.
We were organized for the purpose of receiving, via the spin-off on July 17, 2017, substantially all the assets and liabilities of Vornado's Washington, D.C. segment. On July 18, 2017, we acquired the management business and certain assets and liabilities of JBG.
We have elected to be taxed as a REIT under sections 856-860 of the Code. Under those sections, a REIT which distributes at least 90% of its REIT taxable income as dividends to its shareholders each year and which meets certain other conditions will not be taxed on that portion of its taxable income which is distributed to its shareholders. We currently adhere and intend to continue to adhere to these requirements and to maintain our REIT status in future periods.
As a REIT, we can reduce our taxable income by distributing all or a portion of such taxable income to shareholders. Future distributions will be declared and paid at the discretion of the Board of Trustees and will depend upon cash generated by operating activities, our financial condition, capital requirements, annual dividend requirements under the REIT provisions of the Code, and such other factors as our Board of Trustees deems relevant.
We also participate in the activities conducted by our subsidiary entities that have elected to be treated as TRSs under the Code. As such, we are subject to federal, state, and local taxes on the income from these activities. Income taxes attributable to our TRSs are accounted for under the asset and liability method. Under the asset and liability method, deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements, which will result in taxable or deductible amounts in the future.
We aggregate our operating segments into three reportable segments (multifamily, commercial and third-party asset management and real estate services) based on the economic characteristics and nature of our assets and services.
We compete with many property owners and developers. Our success depends upon, among other factors, trends affecting national and local economies, the financial condition and operating results of current and prospective tenants, the availability and cost of capital, interest rates, construction and renovation costs, taxes, governmental regulations and legislation, population trends, zoning laws, and our ability to lease, sublease or sell our assets at profitable levels. Our success is also subject to our ability to refinance existing debt on acceptable terms as it comes due.

We continue to implement our comprehensive plan to reposition our holdings in the National Landing submarket in Northern Virginia by executing a broad array of Placemaking strategies. Our Placemaking includes the delivery of new multifamily and office developments, locally sourced amenity retail, and thoughtful improvements to the streetscape, sidewalks, parks and other outdoor gathering spaces. In keeping with our dedication to Placemaking, each new project is intended to contribute to authentic and distinct neighborhoods by creating a vibrant street environment with robust retail offerings and other amenities, including improved public spaces. To that end, we saw the delivery of two Placemaking projects, Water Park and Surreal, this year. Additionally, the digital infrastructure investments we are making, including our ownership of CBRS wireless spectrum in National Landing and our agreements with AT&T, Cisco and Federated Wireless, are advancing our efforts to make National Landing among the first 5G-operable submarkets in the nation.
During the second quarter of 2023, we completed the construction of two new office buildings for Amazon on Metropolitan Park in National Landing, totaling 2.1 million square feet, inclusive of approximately 50,000 square feet of street-level retail with new shops and restaurants, and Amazon took occupancy of its new headquarters in June 2023. We are the developer, property manager and retail leasing agent for Amazon's new headquarters at National Landing. As of December
