Fair Value Disclosures [Abstract] |
Fair Value Disclosures [Text Block] | Fair Value Disclosures Fair Value Disclosures The Company uses ASC 820, “Fair Value Measurements and Disclosures” (“ASC 820”), to measure the fair value of certain assets and liabilities. ASC 820 provides a framework for measuring fair value in accordance with GAAP, establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value and requires certain disclosures about fair value measurements. The fair value hierarchy is summarized below:
Level 1: |  | Fair value determined based on quoted prices in active markets for identical assets or liabilities.
Level 2: |  | Fair value determined using significant observable inputs, generally either quoted prices in active markets for similar assets or liabilities or quoted prices in markets that are not active.
Level 3: |  | Fair value determined using significant unobservable inputs, such as pricing models, discounted cash flows, or similar techniques.
Financial Instruments The table below provides, as of the date indicated, a summary of assets (liabilities) related to the Company’s financial instruments, measured at fair value on a recurring basis (amounts in thousands):
|  |  | Fair value
Financial Instrument | Fair value hierarchy |  | January 31, 2013 |  | October 31, 2012
Corporate Securities | Level 2 |  | $ | 246,487 |  |  | $ | 260,772 |
Certificates of Deposit | Level 2 |  | $ | 148,105 |  |  | $ | 148,112 |
Short-Term Tax-Exempt Bond Fund | Level 1 |  | $ | 30,227 |  |  | $ | 30,184 |
Residential Mortgage Loans Held for Sale | Level 2 |  | $ | 49,400 |  |  | $ | 86,386 |
Forward Loan Commitments—Residential Mortgage Loans Held for Sale | Level 2 |  | $ | 649 |  |  | $ | (102 | )
Interest Rate Lock Commitments (“IRLCs”) | Level 2 |  | $ | (1,345 | ) |  | $ | (202 | )
Forward Loan Commitments—IRLCs | Level 2 |  | $ | 1,345 |  |  | $ | 202 |
At January 31, 2013 and October 31, 2012, the carrying value of cash and cash equivalents and restricted cash approximated fair value. Mortgage Loans Held for Sale The table below provides, as of the date 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 January 31, 2013 | $ | 49,304 |  |  | $ | 49,400 |  |  | $ | 96 |
At October 31, 2012 | $ | 84,986 |  |  | $ | 86,386 |  |  | $ | 1,400 |
At the end of the reporting period, the Company determines the fair value of its mortgage loans held for sale and the forward loan commitments it has entered into as a hedge against the interest rate risk of its 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 by applying such pricing to the mortgage loan portfolio. The Company recognizes the difference between the fair value and the unpaid principal balance of mortgage loans held for sale as a gain or loss. In addition, the Company recognizes the fair value of its forward loan commitments as a gain or loss. These gains and losses are included in other income - net. 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 the Company 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. The Company utilizes 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 the Company agrees 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. The Company estimates 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. To manage the risk of non-performance of investors regarding the Forward Commitments, the Company assesses the credit worthiness of the investors on a periodic basis. Marketable Securities The table below provides, as of the date indicated, the amortized cost, gross unrealized holding gains, gross unrealized holding losses and fair value of marketable securities (amounts in thousands):
| January 31, 2013 |  | October 31, 2012
Amortized cost | $ | 424,387 |  |  | $ | 438,755 |
Gross unrealized holding gains | 552 |  |  | 451 |
Gross unrealized holding losses | (120 | ) |  | (138 | )
Fair value | $ | 424,819 |  |  | $ | 439,068 |
The estimated fair values of corporate securities and certificates of deposit are based on quoted prices provided by brokers. The remaining contractual maturities of marketable securities as of January 31, 2013 ranged from 1 month to 23 months. Inventory The Company recognizes 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 the Company's Annual Report on Form 10-K for additional information regarding the Company’s methodology on determining fair value. As further discussed in Note 1 in the Company's Annual Report on Form 10-K, determining the fair value of a community's inventory involves a number of variables, many of which are interrelated. If the Company used a different input for any of the various unobservable inputs used in its impairment analysis, the results of the analysis may 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 communities:
| Selling price per unit (in thousands) |  | Sales pace per year (in units) |  | Discount rate

Investments in Distressed Loans and REO Gibraltar’s distressed loans were recorded at estimated fair value at inception based on the acquisition price as determined by Level 3 inputs and was based on the estimated future cash flows to be generated by the loans discounted at the rates used to value the loans at the acquisition dates. The table below provides, as of the date indicated, the carrying amount and estimated fair value of distressed loans (amounts in thousands):
| January 31, 2013 |  | October 31, 2012
Carrying amount | $ | 42,832 |  |  | $ | 37,169 |
Estimated fair value | $ | 44,065 |  |  | $ | 38,109 |
Gibraltar's REO was recorded at estimated fair value at the time it was acquired through foreclosure or deed in lieu actions using Level 3 inputs. The valuation techniques used to estimate fair value are third-party appraisals, broker opinions of value, or internal valuation methodologies (which may include discounted cash flows, capitalization rate analysis or comparable transactional analysis). Unobservable inputs used in estimating the fair value of REO assets are based upon the best information available under the circumstances and take into consideration the financial condition and operating results of the asset, local market conditions, the availability of capital, interest and inflation rates and other factors deemed appropriate by management. Debt The table below provides, as of the date indicated, the book value and estimated fair value of the Company’s debt (amounts in thousands):
