[1] As of November 30, 2019 and 2018, we had investments in five and six unconsolidated joint ventures, respectively, one of which had a construction loan agreement with a third-party lender to finance its land development activities. The outstanding debt is secured by the corresponding underlying property and related project assets and is non-recourse to us. All of the outstanding secured debt at November 30, 2019 is scheduled to mature in February 2020. However, the loan agreement provides for two-12 month extensions beyond this date. None of our other unconsolidated joint ventures had outstanding debt at November 30, 2019 or 2018.
