[1] As of both May 31, 2020 and November 30, 2019, we had investments in five unconsolidated joint ventures. At November 30, 2019, one of our unconsolidated joint ventures had a construction loan agreement with a third-party lender to finance its land development activities. The outstanding debt was secured by the underlying property and related project assets and was non-recourse to us. All of the outstanding secured debt was repaid in April 2020. None of our unconsolidated joint ventures had outstanding debt at May 31, 2020.
