[1] | As of May 31, 2018 and November 30, 2017, two of our unconsolidated joint ventures had separate construction loan agreements with different third-party lenders to finance their respective land development activities. The outstanding debt under these agreements is secured by the corresponding underlying property and related project assets and is non-recourse to us. Of this outstanding secured debt at May 31, 2018, $9.1 million is scheduled to mature in August 2018 and the remainder is scheduled to mature in February 2020. None of our other unconsolidated joint ventures had outstanding debt at May 31, 2018 or November 30, 2017.
