Fair Value Disclosures [Abstract] |
Fair Value Disclosures [Text Block] | Fair Value Disclosures Financial Instruments The table below provides, as of the dates indicated, a summary of assets (liabilities) related to our financial instruments, measured at fair value on a recurring basis (amounts in thousands):
|  |  | Fair value
Financial Instrument | Fair value hierarchy |  | July 31, 2015 |  | October 31, 2014
Marketable Securities | Level 2 |  | $ | 10,008 |  |  | $ | 12,026 |
Residential Mortgage Loans Held for Sale | Level 2 |  | $ | 127,405 |  |  | $ | 101,944 |
Forward Loan Commitments — Residential Mortgage Loans Held for Sale | Level 2 |  | $ | 516 |  |  | $ | (341 | )
Interest Rate Lock Commitments (“IRLCs”) | Level 2 |  | $ | (858 | ) |  | $ | (108 | )
Forward Loan Commitments — IRLCs | Level 2 |  | $ | 858 |  |  | $ | 108 |
At July 31, 2015 and October 31, 2014, the carrying value of cash and cash equivalents and restricted cash approximated fair value. Marketable Securities The fair value of our marketable securities approximates the amortized cost basis as of July 31, 2015 and October 31, 2014. The estimated fair values of marketable securities are based on quoted prices provided by brokers. The remaining contractual maturity of marketable securities as of July 31, 2015 was four months. Mortgage Loans Held for Sale The table below provides, as of the dates indicated, the aggregate unpaid principal and fair value of mortgage loans held for sale (amounts in thousands):
| Aggregate unpaid principal balance |  | Fair value |  | Excess
At July 31, 2015 | $ | 126,642 |  |  | $ | 127,405 |  |  | $ | 763 |
At October 31, 2014 | $ | 100,463 |  |  | $ | 101,944 |  |  | $ | 1,481 |
At the end of the reporting period, we determine the fair value of our mortgage loans held for sale and the forward loan commitments we have entered into as a hedge against the interest rate risk of our mortgage loans using the market approach to determine fair value. The evaluation is based on the current market pricing of mortgage loans with similar terms and values as of the reporting date and the application of such pricing to the mortgage loan portfolio. We recognize the difference between the fair value and the unpaid principal balance of mortgage loans held for sale as a gain or loss. In addition, we recognize the fair value of our forward loan commitments as a gain or loss. These gains and losses are included in “Other income – net” in our Condensed Consolidated Statements of Operations and Comprehensive Income. Interest income on mortgage loans held for sale is calculated based upon the stated interest rate of each loan and is included in “Other income – net.” IRLCs represent individual borrower agreements that commit us to lend at a specified price for a specified period as long as there is no violation of any condition established in the commitment contract. These commitments have varying degrees of interest rate risk. We utilize best efforts forward loan commitments (“Forward Commitments”) to hedge the interest rate risk of the IRLCs and residential mortgage loans held for sale. Forward Commitments represent contracts with third-party investors for the future delivery of loans whereby we agree to make delivery at a specified future date at a specified price. The IRLCs and Forward Commitments are considered derivative financial instruments under ASC 815, “Derivatives and Hedging,” which requires derivative financial instruments to be recorded at fair value. We estimate the fair value of such commitments based on the estimated fair value of the underlying mortgage loan and, in the case of IRLCs, the probability that the mortgage loan will fund within the terms of the IRLC. The fair values of IRLCs and forward loan commitments are included in either “Receivables, prepaid expenses and other assets” or “Accrued expenses” in our Condensed Consolidated Balance Sheets, as appropriate. To manage the risk of non-performance of investors regarding the Forward Commitments, we assess the credit worthiness of the investors on a periodic basis. Inventory We recognize inventory impairment charges based on the difference in the carrying value of the inventory and its fair value at the time of the evaluation. The fair value of the aforementioned inventory was determined using Level 3 criteria. Estimated fair value is primarily determined by discounting the estimated future cash flow of each community. See Note 1, “Significant Accounting Policies – Inventory” in our Annual Report on Form 10-K for the year ended October 31, 2014, for additional information regarding our methodology for determining fair value. As further discussed in Note 1 in our Annual Report on Form 10-K for the year ended October 31, 2014, determining the fair value of a community’s inventory involves a number of variables, many of which are interrelated. If we had used a different input for any of the various unobservable inputs used in our impairment analysis, the results of the analysis might have been different, absent any other changes. The table below summarizes, for the periods indicated, the ranges of certain quantitative unobservable inputs utilized in determining the fair value of impaired operating communities:
