ORGANIZATION OF THE PARENT COMPANY AND THE OPERATING PARTNERSHIP | 1. ORGANIZATION OF THE PARENT COMPANY AND THE OPERATING PARTNERSHIP Brandywine Realty Trust (the “Parent Company”) is a self-administered and self-managed real estate investment trust (“REIT”) engaged in the acquisition, development, redevelopment, ownership, management, and operation of a portfolio of office and mixed-use properties. The Parent Company owns its assets and conducts its operations through Brandywine Operating Partnership, L.P. (the “Operating Partnership”) and subsidiaries of the Operating Partnership. The Parent Company is the sole general partner of the Operating Partnership and, as of September 30, 2024, owned a 99.7% interest in the Operating Partnership. The Parent Company’s common shares of beneficial interest (“common shares”) are publicly traded on the New York Stock Exchange under the ticker symbol “BDN.” The Parent Company, the Operating Partnership, and their consolidated subsidiaries are collectively referred to as the “Company.” As of September 30, 2024, the Company owned and consolidated 67 properties that contained an aggregate of approximately 12.5 million net rentable square feet (collectively, the “Properties”). The Company’s core portfolio of operating properties (the “Core Properties”) exclude properties under development or redevelopment properties, recently completed - not stabilized properties, and properties held for sale. The Properties were comprised of the following as of September 30, 2024:
| Number of Properties |  | Rentable Square Feet
Office properties | 60 |  |  | 11,252,377 |
Mixed-use properties | 4 |  |  | 924,450 |
Core Properties | 64 |  |  | 12,176,827 |
Development/redevelopment properties | 2 |  |  | 144,685 |
Recently completed - not stabilized properties (a) | 1 |  |  | 168,294 |
The Properties | 67 |  |  | 12,489,806 |
(a)The Company reclassifies a Property from “development/redevelopment property” to “recently completed – not-stabilized property” after the date that the development or redevelopment of the Property is placed in service and prior to the time that the Property reaches at least 90% occupy. At such time as the Property reaches at least 90% occupancy, the Company reclassifies the Property as a “Core Property.” In addition to the Properties, as of September 30, 2024, the Company owned 130.6 acres of land held for development. The Company also held a leasehold interest in one land parcel totaling 0.8 acres, acquired through a prepaid 99-year ground lease, and held options to purchase approximately 5.1 additional acres of undeveloped land. As of September 30, 2024, the total potential development that this inventory of land could support under current zoning and entitlements, including the parcels under option, amounted to an estimated 11.9 million net rentable square feet. As of September 30, 2024, the Company also owned economic interests in thirteen unconsolidated real estate ventures (see Note 4“Investment in Unconsolidated Real Estate Ventures,” for further information). The Properties and the properties owned by the unconsolidated real estate ventures are primarily located in or near Philadelphia, Pennsylvania; Austin, Texas; Metropolitan Washington, D.C.; Southern New Jersey; and Wilmington, Delaware. The Company conducts its third-party real estate management services business primarily through wholly-owned management company subsidiaries. As of September 30, 2024, the management company subsidiaries were managing properties containing an aggregate of approximately 20.4 million net rentable square feet, of which approximately 12.5 million net rentable square feet relate to Properties owned by the Company and approximately 7.9 million net rentable square feet relate to properties owned by the unconsolidated real estate ventures. Unless otherwise indicated, all references in this Form 10-Q to square feet and net rentable square feet represent net rentable area.
