Receivables [Abstract]
Receivables	Receivables Receivables of $152.7 million at November 30, 2015 and $125.5 million at November 30, 2014 primarily included amounts due from utility companies and municipalities; escrow deposits to be refunded; and estimated minimum probable recoveries of water intrusion-related repair costs, as described in Note 15. Commitments and Contingencies. Receivables from utility companies and municipalities typically relate to infrastructure improvements we make with respect to our communities. We are generally reimbursed for the cost of such improvements when they are accepted by the utility company or municipality, or after certain events occur, depending on the terms of the applicable agreements. These events may include, but are not limited to, the connection of utilities or the issuance of bonds by the respective municipalities. Each receivable is evaluated for collectibility at least quarterly, and allowances for potential losses are established or maintained on applicable receivables when collection becomes doubtful, taking into account historical experience, prevailing economic conditions and other relevant factors. Receivables were net of allowances for doubtful accounts of $12.2 million in 2015 and $15.3 million in 2014.

Commitments and Contingencies. Receivables from utility companies and municipalities typically relate to infrastructure improvements we make with respect to our communities. We are generally reimbursed for the cost of such improvements when they are accepted by the utility company or municipality, or after certain events occur, depending on the terms of the applicable agreements. These events may include, but are not limited to, the connection of utilities or the issuance of bonds by the respective municipalities.

Each receivable is evaluated for collectibility at least quarterly, and allowances for potential losses are established or maintained on applicable receivables when collection becomes doubtful, taking into account historical experience, prevailing economic conditions and other relevant factors. Receivables were net of allowances for doubtful accounts of $12.2 million in 2015 and $15.3 million in 2014.
