[1] As of November 30, 2017 and 2016, two and one of our unconsolidated joint ventures, respectively, 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 November 30, 2017, $19.8 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 November 30, 2017 or 2016.
