[1] Other assets at February 29, 2024 and November 30, 2023 included $35.7 million and $34.4 million, respectively, of contract assets for estimated future renewal commissions.

[2] As of both February 29, 2024 and November 30, 2023, one of our unconsolidated joint ventures had borrowings outstanding under a revolving line of credit it entered into with a third-party lender in April 2022 to finance its land acquisition, development and construction activities. Borrowings under this line of credit, which has a maximum commitment of $62.0 million, are secured by the underlying property and related project assets. The line of credit is scheduled to mature on April 19, 2026, unless extended or terminated pursuant to its applicable terms. None of our other unconsolidated joint ventures had outstanding debt at February 29, 2024 or November 30, 2023
