[1] Other assets at May 31, 2024 and November 30, 2023 included $37.8 million and $34.4 million, respectively, of contract assets for estimated future renewal commissions.

[2] As of both May 31, 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. In April 2024, the revolving line of credit was amended, increasing the aggregate commitment to $70.0 million from $62.0 million, with the amount of all advances through October 2024 not to exceed $80.0 million. Borrowings under the line of credit 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 May 31, 2024 or November 30, 2023
