[1] Other assets at August 31, 2025 and November 30, 2024 included $38.4 million and $38.2 million, respectively, of contract assets for estimated future renewal commissions.

[2] As of both August 31, 2025 and November 30, 2024, the unconsolidated joint venture in California that delivered homes in the three-month and nine-month periods ended August 31, 2025 and 2024 had borrowings outstanding under a term loan with a third-party lender to finance its land acquisition, development and construction activities. In January 2025, the loan agreement was amended, increasing the aggregate commitment to $60.0 million from $55.0 million, and providing an eight-month loan extension option to replace the two previous six-month extension options. Pursuant to the amendment, the aggregate commitment was reduced to $55.2 million on August 31, 2025, and will be reduced to $40.0 million on February 28, 2026. This term loan is scheduled to mature on April 19, 2026, unless extended or terminated pursuant to its applicable terms. If the term loan is extended, the aggregate commitment would be reduced to $28.0 million effective April 19, 2026. Borrowings under the term loan are secured by the underlying property and related project assets. None of our other unconsolidated joint ventures had outstanding debt at August 31, 2025 or November 30, 2024

[3] Cash and cash equivalents included restricted cash of $.8 million at August 31, 2025 and $1.3 million at November 30, 2024
