[1] Other assets at February 28, 2025 and November 30, 2024 included $38.5 million and $38.2 million, respectively, of contract assets for estimated future renewal commissions.

[2] As of both February 28, 2025 and November 30, 2024, the unconsolidated joint venture in California that delivered homes in the three months ended February 28, 2025 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 will be reduced to $55.2 million on August 31, 2025, and then 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 February 28, 2025 or November 30, 2024

[3] Cash and cash equivalents includes restricted cash of $1.3 million at both February 28, 2025 and November 30, 2024
