[1] As of both February 29, 2020 and November 30, 2019, we had investments in five unconsolidated joint ventures, 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 underlying property and related project assets and is non-recourse to us. All of the outstanding secured debt at February 29, 2020 is scheduled to mature in February 2021. However, the loan agreement provides for a one-year extension beyond this date. None of our other unconsolidated joint ventures had outstanding debt at February 29, 2020 or November 30, 2019.
